Have the exterior cleaned a few days before your listing photos. Wash the siding first, then the driveway, walks and porch, and finish with the windows. That order keeps runoff off clean glass, and the short gap gives everything time to dry without letting new grime or pollen settle back in.
Your listing photos are the first showing, and the front of the house carries a lot of weight. A green streak under the eaves or a gray, stained driveway reads as “deferred maintenance” in a thumbnail, even when the inside is spotless.
Inside a home, a photographer can control light, angles and staging. Outside, the camera shows exactly what is there. In the Lowcountry, that often includes:
Humidity and warm weather help mildew and algae come back quickly, so a house that looked fine last fall can look streaky by listing day.
Use this table as a walk-around. Stand at the curb where the photographer will likely stand, then work around the house.
| Area | What buyers (and cameras) notice | What to keep in mind |
|---|---|---|
| Siding | Green or black streaks, dull color, dirt under eaves | Soft washing: low pressure with a cleaning solution that kills growth at the root |
| Driveway and walks | Dark tire tracks, mildew, rust and clay stains, oil spots | Concrete can take more pressure, but even, consistent passes keep it from drying with stripes |
| Windows | Water spots, salt film, pollen haze, dirty screens | Clean the glass after the siding and gutters are done |
| Gutters | Black streaks on the outside face, overflowing debris | Overflowing gutters can raise drainage questions at the inspection |
| Porch and patio | Mildew on floors, cobwebs in corners, grime on railings | Painted railings and ceilings need a gentler approach than a concrete floor |
| Fences | Gray or green boards, mildew at the base | Wood needs low pressure so the boards don’t gouge or fuzz |
You don’t need every line item. If your budget or timeline is tight, start with what shows up in the main front photo: usually the siding, the driveway and the front windows.
Siding is the largest surface in almost every exterior shot, so it has the biggest effect on the photo. Vinyl, fiber cement, stucco and painted wood should not be blasted with high pressure. It can force water behind the siding, strip paint, or etch the surface.
Soft washing uses low pressure and a cleaning solution that breaks down mildew and algae so they rinse away. The result looks even across the whole wall, which matters under a wide-angle lens, and it holds up for in-person showings weeks later.
A clean driveway frames the house. A stained one pulls the eye to the bottom of the photo.
Concrete can handle higher pressure, but technique still matters. Uneven pressure washing leaves light and dark “zebra stripes” across the slab. Those stripes are hard to see in person and easy to see in a drone shot.
Include the front walk, the steps and the porch floor. Buyers walk that path at every showing.
Windows go last for a practical reason. Washing the siding and gutters sends dirty water down the walls, and some of it lands on the glass. Clean the windows after that work is done and they stay clear for the photos.
Clean glass also helps the interior shots: more natural light, and a sharp view of the yard or the marsh. If your glass has salt film or pollen haze, window cleaning before photo day is worth it.
Gutters show up in nearly every exterior photo, and black streaks on the outside face stand out against light trim. Full gutters matter for the home inspection too, since overflow can lead to questions about drainage. If yours are packed with leaves, schedule gutter cleaning before the inspector arrives.
Fences are easy to forget until you see the backyard photos. A gray or green fence makes the whole yard look older. Wood needs a gentle approach so the boards don’t splinter or fuzz.
The goal is to have everything clean and fully dry on photo day, without leaving enough time for the house to get dirty again.
If you’re selling in spring, keep pine pollen in mind. It can coat a freshly cleaned porch in a yellow film quickly, so keep the cleaning close to the photo date.
We agree on the price before any work starts, so there are no surprises when you’re already juggling a move. You don’t need to be home for most exterior jobs, which helps if you’ve already relocated or you’re busy staging inside. If we miss a spot, we come back and fix it.
A few days before the photos is a good target. That gives siding, concrete and wood time to dry evenly. It is still close enough that new dirt or pollen has little time to build up.
High pressure can damage siding, which is why siding should be soft washed instead. Soft washing uses low pressure and a cleaning solution to remove mildew and algae. It is the safer method for vinyl, fiber cement, stucco and painted surfaces.
Start with what appears in the main front photo. For most homes that means the siding, the driveway and the front windows. Add the porch, fences and back of the house if time and budget allow.
For most exterior jobs, no. That makes it easier to schedule around a move, even if you’ve already relocated.
If your listing date is coming up, call Mount Pleasant Pressure Washing at (843) 471-0799 or request a quote online. Mention your photo date when you reach out.
If your HOA sent a letter about mildew or algae on your siding, find the compliance deadline, book a soft wash before that date, and keep before and after photos plus your receipt as proof. Green and black growth on siding is a cleaning problem, not a repair problem, and it usually clears in a single visit.
Siding growth is a routine HOA notice in the Lowcountry, and it’s rarely a sign of neglect. Warm, humid air off the marsh and the rivers keeps siding damp for long stretches, and shaded walls stay damp the longest. Algae and mildew grow wherever moisture sits, so even a well-kept home can turn green on its north side between cleanings.
That’s the good news. The less pleasant part is that these letters come with a clock. If the date passes without action, many associations move to a second notice or a formal violation. Your own HOA’s documents spell out what happens next, so treat the first letter as the easiest stage to resolve.
Before you call anyone, pull out four details from the notice:
If any of this is unclear, email the management company and ask. A short written question also creates a record that you responded promptly, which helps if you need a few extra days.
A few days of rain can push outdoor appointments back, so waiting until the final week leaves you no cushion. Call as soon as the letter arrives and tell us your deadline. Mention every item on the letter so the quote covers all of it at once.
This is also where not needing to be home matters. You don’t need to be home for most exterior jobs, so you can be at work, out of town or busy inside on cleaning day.
Green and black growth on siding is living organic material. Blasting it with high pressure removes the visible layer but often leaves roots behind, so it comes back fast. High pressure can also force water behind vinyl siding, etch soft wood, and strip paint or caulk.
The standard fix for siding is a soft wash. A soft wash uses a cleaning solution applied at low pressure, followed by a gentle rinse. The solution kills the mildew and algae rather than just knocking off the surface layer, which is why the result lasts longer than a pressure-only wash.
Hard surfaces are different. Concrete driveways, sidewalks and pool decks can handle more pressure, and that’s where pressure washing belongs.
| Surface on the letter | Typical growth | Usual method |
|---|---|---|
| Vinyl siding | Green algae, black mildew | Soft wash |
| Painted wood or fiber cement siding | Mildew, dark streaks | Soft wash |
| Brick or stucco walls | Green or black staining | Soft wash |
| Fascia, soffits and trim | Mildew, spider webs | Soft wash |
| Concrete driveway and walkways | Algae, dark staining | Pressure washing |
If you’re not sure which surfaces need what, describe the letter when you call and we’ll walk you through it.
Before you book any exterior cleaning, ask the company how they protect landscaping and control runoff. It’s a fair question, and a confident answer is a good sign.
Close your windows on cleaning day and move anything fragile off the porch.
Once the job is done, build a simple file you can send to the management company:
Save a copy of everything. If the HOA re-inspects and has a question, you’ll have it ready. If the company you hired missed a spot, call them back. When we miss a spot, we come back and fix it, so your proof photos match what the inspector sees.
Siding growth returns over time, especially on shaded walls and near trees. A regular house wash keeps you ahead of HOA inspections instead of reacting to them. A few small habits help between cleanings:
If you want a sense of timing, our post on when to pressure wash your house covers seasons and scheduling.
How fast can I get my siding cleaned after an HOA notice? It depends on the weather and the schedule at the time, so call as soon as the letter arrives and tell us your deadline. Booking early also leaves room if rain pushes the appointment.
Will pressure washing remove mildew from vinyl siding? High pressure can strip off the visible growth, but it often leaves the roots and can force water behind the panels. A soft wash uses a cleaning solution at low pressure that kills the growth, so it stays clean longer and the siding isn’t damaged.
Do I need to be home for the cleaning? No. You don’t need to be home for most exterior jobs. Take your own before photos ahead of time and your after photos once the job is done, so you have what your HOA needs.
What should I send my HOA to prove the work is done? Send before and after photos taken from the street, a copy of your receipt with the service date, and a short note referencing the original notice. Check your letter in case your HOA wants it sent a specific way, such as through a portal.
If an HOA letter just landed on your counter, we can take it from here. You’ll get upfront pricing before any work starts, you don’t need to be home, and if we miss a spot we’ll come back and fix it. Call (843) 471-0799 or request a quote online and tell us your deadline.
Orange rust stains on a driveway or sidewalk almost always come from iron. The most common source is irrigation water from a well, which can carry dissolved iron that turns orange once it dries on concrete. Fertilizer and metal furniture cause the rest. The stains return because the source keeps delivering new iron until you change it.
Rust is iron oxide. When iron-rich water dries on concrete, the iron reacts with oxygen and leaves an orange deposit. Concrete is porous, so that deposit settles into the surface rather than sitting on top.
That detail matters for cleaning. Dirt, mildew and algae sit mostly on the surface and respond well to water pressure and the right detergent. Rust has bonded into the pores of the concrete. Spraying it harder does very little, and pushing too much pressure at it can scar the surface while the stain stays put.
Irrigation that draws from a well can carry dissolved iron. Every time the sprinklers run, they mist that water across your driveway edges, sidewalk and curb.
The pattern gives it away. Irrigation rust shows up as fan-shaped or arc-shaped orange bands that line up with where the sprinkler heads throw water. It is usually heaviest closest to the head and fades toward the middle of the slab.
Many lawn fertilizers contain iron because it helps grass green up. When granules bounce off the spreader onto concrete and get wet, each one can leave a small orange speckle. A scatter of dots along the driveway edge after a lawn treatment is a common sign.
Patio chairs, grill stands, wrought-iron planters and tools left out in the rain all leave rust behind, usually in the shape of whatever caused it: rings, rectangles or chair-leg footprints.
A rust stain is a symptom. If the source is still active, the concrete will stain again no matter how well it was cleaned.
This is also why a standard wash alone disappoints on rust. The concrete comes up clean everywhere except the orange bands, which stand out even more against the brighter slab.
| What you see | Likely source | How to stop it returning |
|---|---|---|
| Orange arcs or fan shapes along the slab edges | Sprinkler overspray from well water | Adjust or redirect heads; ask an irrigation tech about iron filtration |
| Small orange dots near the lawn edge | Iron-containing fertilizer | Blow granules off hard surfaces before watering; ask your lawn service to use a deflector |
| Rings, squares or footprints | Metal furniture, planters, tools | Add feet or pads, or move metal items off the concrete |
| Streaks running down from a fixture | Rusting railing, hose bib or hardware | Repair or replace the rusting metal |
Before anyone cleans the stain, it pays to cut off the supply.
Adjust your sprinkler heads. This is the single most useful step for irrigation rust. Most rotor and spray heads can be turned or have their arc reduced so they water the lawn instead of the concrete. A nozzle with a tighter pattern helps too, and an irrigation company can handle it during a routine check.
Ask about the water itself. If your system runs on well water with noticeable iron, an irrigation or water treatment specialist can tell you whether filtration or a treatment system makes sense for your setup.
Keep fertilizer and metal off the slab. Blow stray granules back onto the lawn before the next watering, and put rubber or plastic feet under chairs and planters.
Removing rust from concrete is a chemistry job more than a pressure job. Professionals generally use cleaners made specifically for rust on masonry. These products react with iron oxide and turn it into a compound that dissolves in water, so it can be rinsed out of the pores instead of blasted.
Done well, the work usually starts with confirming the stain really is rust, since red clay, leaf tannin and some algae can look similar and each needs a different approach. Surrounding plants and surfaces are typically protected, the treatment is given time to work, and the area is rinsed at controlled pressure so the concrete surface is not damaged. Washing the whole slab afterward helps the treated area blend in.
This guide doesn’t include DIY mixing instructions for rust removers. Acid-based products can etch concrete, harm plants and react badly with other cleaners. If you try a store-bought product, follow its label exactly and test a hidden spot first. Our guide to common pressure washing mistakes covers why high pressure on its own causes more harm than good.
Once the source is under control, routine cleaning keeps the concrete looking even. Our post on how often to pressure wash your driveway covers a realistic schedule for Mount Pleasant weather. New orange marks between cleanings usually mean a sprinkler head has drifted.
Orange stains on concrete are almost always rust. The usual causes are well water from your irrigation system, iron-containing fertilizer, or metal furniture and planters. The shape of the stain usually points to the source.
Pressure alone rarely removes rust, because the iron has settled into the pores of the concrete. Rust generally needs a cleaner designed to dissolve it, followed by a controlled rinse. Turning the pressure up to force it out can scar the surface.
Adjust the sprinkler heads so they water the lawn and beds instead of the concrete, and reduce the spray arc where heads sit near hard surfaces. If your system uses well water with high iron, ask an irrigation or water treatment specialist about filtration options.
Yes, if the source is still active. A professional treatment removes the existing stain, but sprinklers, fertilizer or metal items will create new ones over time. Fixing the source is what keeps the concrete clean.

Picture a tenant pulling into your property for the first time. What do they see? Green streaks on the walls, gum ground into the sidewalk, a dingy awning, and an oil-stained parking lot.
They haven’t met you yet. But they’ve already made up their mind. Sound familiar?
Here’s the thing. For a property manager, a dirty building isn’t just an eyesore. It quietly tells tenants and customers that nobody’s paying attention. And when the outside looks neglected, people start to wonder about everything else.
The good news is that this is a fixable problem. In this article, you’ll learn what tenants actually notice, why Charleston buildings get grimy so fast, and how the right pressure washing plan keeps your property looking sharp all year. Let’s get into it.
Most people can’t explain why a building feels “off.” They just feel it.
A clean entrance says, “This place is cared for.” A grimy one says the opposite. The entry glass, the sidewalk, the sign out front, the dumpster corral around back. These are the spots that shape a first impression in seconds.
And those impressions stick around. A tenant deciding whether to renew a lease notices the little things. So does a customer choosing between your shopping center and the cleaner one down the road.
That’s the frustrating part, right? You can run a great property on the inside. But if the outside is dirty, all that hard work hides behind a layer of grime.
Look, this isn’t your fault. The Lowcountry is just tough on buildings.
Our salt air, heavy humidity, and the shade from all those beautiful live oaks create the perfect home for mold, mildew, and algae. Those dark streaks running down your walls? That’s usually algae, not dirt. And it grows back fast.
Pollen coats everything in spring. Grease builds up around dumpster pads. Tire marks and oil soak into the parking lot. It piles up week after week, and before long your building looks years older than it really is.
But here’s what matters. Because this stuff keeps coming back, a one-time cleaning only takes you so far. The buildings that stay sharp are the ones cleaned on a regular rhythm. That’s exactly the problem Mount Pleasant Pressure Washing was built to solve for busy property managers across the Charleston area.
Now, here’s a mistake that costs property owners real money. They assume every surface needs the same high-pressure blast. It doesn’t.
Too much pressure can crack stucco, strip paint, tear awning fabric, and ruin a sign. The skill isn’t spraying hard. It’s knowing when to go gentle. So we match the method to the surface, using soft washing where high pressure would do harm, and stronger pressure where it’s safe and needed.
What does that look like in real life? Here’s a quick guide for a typical commercial property.
| Surface | Common Lowcountry Problem | Right Method | Suggested Frequency |
| Building facade (stucco, brick, siding) | Algae streaks and mildew from humidity and shade | Soft washing | 1 to 2 times a year |
| Sidewalks and entryways | Gum, dirt, and slippery algae | Pressure washing | Every 3 to 6 months |
| Parking lots | Oil stains, tire marks, grime | Pressure washing | 1 to 2 times a year |
| Awnings and canopies | Salt film, mildew, faded look | Soft washing (low pressure) | 1 to 2 times a year |
| Signs and storefront glass | Salt spray, pollen, film | Soft wash and window cleaning | Quarterly |
| Dumpster pads | Grease, odor, pests | Hot-water pressure washing | Monthly to quarterly |
See the pattern? Different surfaces, different methods, different schedules. Getting this right is the difference between a building that looks clean and one that gets damaged in the name of cleaning.
Here’s something a lot of managers miss. Algae and mildew on a walkway aren’t only ugly. They’re slippery.
A slick sidewalk or entryway is a fall waiting to happen. And a fall on your property can turn into a complaint, an injury, or a liability claim. Cleaning those surfaces protects people, not just your image.
The same goes for graffiti. A tagged wall sends a message you don’t want tenants reading. Quick graffiti removal keeps your property feeling safe and looked-after.
Want to know the secret to a building that always looks ready? You stop cleaning by emergency.
Most managers wait until the grime is obvious, then scramble to book a deep clean before a big tour or inspection. It’s stressful. It’s also more expensive, because built-up algae and baked-in stains take far more work to remove.
A recurring plan flips that around. The same trusted crew shows up on a set schedule, before the buildup ever gets bad. Your property stays consistent, and you stop thinking about it. We also work around your tenants’ hours, cleaning early or after close, so we never get in the way of their customers.
That’s the relief part. With Mount Pleasant Pressure Washing handling the schedule, a clean exterior becomes one less thing on your already full plate. We take care of the storefront glass and window cleaning, the facades, the sidewalks, the parking areas, all of it. Our crew has cleaned storefronts, office parks, and multi-tenant buildings all over Mount Pleasant, so we know how to keep a busy property looking its best without slowing it down.
How often should a commercial building be pressure washed in Charleston? For most properties here, facades and sidewalks do well with a cleaning once or twice a year, while dumpster pads need it far more often. Our humidity and oak shade speed up algae growth, so coastal buildings usually need more frequent care than ones farther inland. We look at each property and suggest a rhythm that fits it.
Will pressure washing damage my building’s facade or signs? It can, if the wrong method is used. High pressure can harm stucco, paint, awnings, and signage. That’s why we soft wash those surfaces with low pressure and the right cleaning solution, then save stronger pressure for concrete and parking lots where it belongs.
Can you clean without disrupting my tenants and their customers? Yes. We schedule around your business hours, including early mornings and after close, so the work gets done without interrupting foot traffic. For multi-tenant properties, we plan the route so each storefront stays open and reachable.
Is a recurring cleaning plan really worth it? For most commercial properties, it is. Regular cleaning stops grime from baking in, which keeps each visit faster and protects your surfaces over time. It also means your building always looks ready, with no last-minute scramble before a tour or inspection.
Let’s bring it home. Your property’s exterior is the first thing tenants and customers see, and it speaks for you before you say a single word.
In a climate as tough as ours, keeping that first impression sharp takes the right method, the right schedule, and a crew that treats your property like its own. That’s the whole job. And it’s what we do, day in and day out, across Mount Pleasant and Charleston.

Salt air leaves a thin, sticky film outside your home. On windows it shows up as haze. On siding it holds dirt and mildew. On metal railings and fixtures it speeds up corrosion. The fix is regular rinsing with fresh water and gentle cleaning methods, not high pressure, which can damage the very surfaces you are trying to protect.
When wind moves across the harbor, the marsh or the tidal creeks, it carries fine droplets of salt water inland. The water evaporates and the salt stays behind. Over days and weeks, that residue builds into a dull coating on glass, siding, trim and metal.
Salt also attracts moisture from the air. On a humid Lowcountry morning, a salty surface stays damp longer than a clean one. That damp, gritty layer gives pollen, dust and mildew something to cling to, so a coastal home tends to look dirty faster than the same house would farther inland.
You will notice it most on the side of the house that faces the water or the prevailing wind. Homes closest to open water, whether a tidal creek, the river, the marsh or the harbor, usually see it first.
Salt does not damage every surface the same way. Here is what to watch for and how each surface should be cleaned.
| Surface | What salt does | Safer cleaning approach |
|---|---|---|
| Windows and glass doors | Leaves a cloudy haze and spotting that blocks the view | Hand cleaning with fresh water and proper glass tools |
| Vinyl, fiber cement and painted siding | Holds dirt, pollen and mildew; dulls the finish | Low-pressure soft washing, then a thorough rinse |
| Aluminum and steel railings | Speeds up pitting, white powdery corrosion and rust | Gentle wash and fresh-water rinse; no abrasive scrubbing |
| Light fixtures, hinges, hose bibs | Corrodes finishes and stiffens moving parts | Hand wipe and rinse; avoid blasting water into seals |
| Window and porch screens | Clogs the mesh and weakens it over time | Low-pressure rinse; never a narrow, high-pressure tip |
| Outdoor AC units | Coats the fins with residue | Gentle spray only; follow the manufacturer’s guidance or ask an HVAC technician |
It is tempting to grab a pressure washer and blast the salt away. On a coastal home, that often causes more harm than the salt does.
High pressure can force water behind siding and into window seals. It can etch glass, strip paint, and tear screen mesh. On metal railings that already have small pits from corrosion, aggressive spraying or scrubbing can open up the protective finish and expose more bare metal to the next round of salt.
Salt dissolves in water. You do not need force to remove it, you need enough fresh water and enough time on the surface to carry it off. That is why soft washing, a low-pressure method, is the usual approach for siding. A gentle wash and a complete rinse take off the salt along with the mildew and grime that grow on top of it, without the side effects of high pressure.
Salt haze on glass is the complaint homeowners notice first, because it changes the view. A few practical points:
High and hard-to-reach glass is where many homeowners stop. Ladders on sandy or uneven ground near the water are a real fall risk. If that describes your house, call us about window cleaning for your home.
Metal takes the hardest hit from salt air. Aluminum railings develop a white, chalky oxidation. Steel and iron rust, especially at welds, fasteners and anywhere paint has chipped. Exterior light fixtures, door hardware and hose bibs lose their finish faster near the water.
Regular fresh-water rinsing slows that process because it removes the salt before it has long to work. Use a soft cloth or brush, not steel wool or abrasive pads, which scratch the finish and give corrosion a new place to start. If you see bubbling paint, flaking or deep rust on a railing, have it looked at by someone who repairs metalwork. Structural railings are a safety item, not just a cosmetic one.
There is no single schedule that fits every house, because exposure depends on how close you are to open water and which way the wind usually blows. A useful rule: the closer you are to the harbor or the marsh, the more often salt needs to come off.
Many coastal homeowners rinse windows and railings themselves between professional cleanings, then schedule a full exterior wash once the film and mildew start to show. For timing your full house wash around pollen season and summer heat, see our guide on when to pressure wash your house.
You get upfront pricing, so the price is agreed before any work starts. You do not need to be home for most exterior jobs. And if we miss a spot, we come back and fix it.
You can, but it is usually the wrong tool. High pressure can push water behind siding, damage window seals, and tear screens. Salt dissolves easily in fresh water, so a low-pressure wash and a thorough rinse remove it without the risk.
The most common cause is salt or cleaning residue drying on the glass before it is fully rinsed off. Cleaning in direct sun makes it worse, because the glass dries too quickly. Rinsing well and working in the shade usually solves it.
Yes. Aluminum does not rust like steel, but salt causes it to oxidize and pit, which shows up as white, chalky spots. Rinsing with fresh water regularly and avoiding abrasive scrubbing helps protect the finish.
It can be. Wind carries salt inland, so homes away from the shoreline still collect some film, just more slowly. If your windows look dull or your railings show white spots, salt is likely part of the reason.

Before a storm, clear your gutters and downspouts, make sure water drains away from the foundation, and secure anything loose in the yard. After it passes, check that gutters are still attached and flowing, clear packed debris, and rinse wind-driven salt and grime off siding and windows before the film sets in.
Hurricane season in the Atlantic runs from June through November. In Mount Pleasant, that means half the year with the marsh, the harbor and the ocean all close enough to push rain, wind and salt air straight at your house. Most storms that reach us are tropical systems and heavy rain bands rather than direct hits, but even those can overwhelm a gutter system that wasn’t ready.
This checklist covers the outside of your home in two parts: what to do before a storm, and what to do once it has moved through.
A normal summer shower gives your gutters time to drain. A tropical system can dump rain for hours, often sideways. If the gutter is half full of leaves and pine straw, water spills over the front edge and lands right next to your foundation, your flower beds and your crawl space vents.
Clogged downspouts make it worse. Water backs up into the gutter, adds weight, and pulls on the hangers. That is how gutters start to sag or separate from the fascia board during a long storm.
If you’re not sure whether your gutters are in good shape right now, our post on the seven signs of clogged gutters walks through what to look for from the ground.
Start this early in the season, ideally in late spring, and repeat a quick check when a named storm shows up in the forecast. Do not climb a ladder once wind picks up.
Clear the gutters. Remove leaves, pine needles, seed pods and the muck that settles at the bottom. Live oaks and pines drop debris year round here, so a gutter that was clean in March may not be clean in August.
Flush the downspouts. A clear gutter does nothing if the downspout is packed. Run water through each one and watch that it exits freely at the bottom.
Check the extensions. Downspout extensions and splash blocks should send water several feet away from the house. Storm runoff is exactly what they’re for.
Look at the hangers. Loose or missing gutter hangers are easy to spot from the ground. Sections that already sag are the most likely to fail under a full load of water.
Secure the yard. Bring in or tie down patio furniture, planters, grills, trash cans and kids’ toys. Anything light enough to move in a strong gust can end up against your siding or windows.
Take photos. A few quick pictures of your siding, windows, gutters and yard give you a clear before-and-after record if you need one later.
If you’d rather not be on a ladder in July heat, book a gutter cleaning early in the season, before the forecast gets busy.
Wait until the storm has fully passed and it’s safe to be outside. Watch for downed power lines, standing water and damaged limbs that are still hanging. Leave anything structural or electrical to the right professional.
Walk the perimeter. Look for gutter sections that have pulled away, bent downspouts, and debris piled against the house.
Check gutter flow. A storm can pack gutters with leaves, twigs and grit in a single afternoon. If you see water spilling over the edge during the next rain, they need clearing again.
Clear debris from walkways and drives. Wet leaves and storm grit on concrete get slick and can leave stains if they sit.
Look for salt and grime film. Wind-driven rain near the water carries salt, sand and organic debris. When it dries, it leaves a dull, hazy film on siding and glass.
Rinse before it bakes on. Lowcountry sun and humidity after a storm help that film settle in and give mildew something to feed on. The sooner it comes off, the easier it is to remove.
| Area | Before the storm | After the storm |
|---|---|---|
| Gutters | Clear leaves, needles and sludge | Check for new debris and overflow |
| Downspouts | Flush and confirm free flow | Check for bends, clogs and loose joints |
| Extensions and splash blocks | Point water away from the foundation | Reset any that washed out or shifted |
| Gutter hangers | Tighten or replace loose ones | Look for sagging or pulled sections |
| Yard items | Bring in or tie down | Clear anything blown against the house |
| Siding | Take reference photos | Look for salt film, grime and stuck debris |
| Windows | Close and latch, take photos | Check for haze, streaks and salt spotting |
| Walkways and driveway | Clear loose debris | Remove wet leaves and grit before staining |
Salt film is the part most people miss. It doesn’t look like much at first, just a slightly cloudy window or siding that seems a shade duller. Over time it holds moisture against the surface and gives dirt and mildew something to cling to.
Siding usually needs a low-pressure wash, not a blast. High pressure on siding that has just taken a beating from wind can force water behind panels or damage weakened trim. A soft wash uses gentle pressure and the right cleaning solution to lift the film without stressing the surface.
Glass is its own job. Salt spotting and storm haze can leave windows streaky even after a few rainy days, because rain alone rarely rinses it clean. A proper window cleaning is the usual fix when the haze won’t come off on its own.
A good rhythm is one full gutter cleaning before the season starts, a quick look whenever a storm is forecast, and a post-storm check after any system that brings sustained wind or heavy rain. Homes under heavy tree cover may need more than one cleaning between June and November.
Yes. Clear gutters and open downspouts move storm water away from your foundation instead of spilling it next to the house. Do it well before the storm arrives, since ladders and high wind don’t mix.
Once the storm has passed and it’s safe outside, sooner is better. Salt and grime film settles in as it dries in the sun and humidity. Rinsing it off within a few weeks keeps it from becoming a mildew problem.
High pressure on siding is usually the wrong tool, especially right after a storm when panels or trim may be loose. A soft wash at low pressure removes salt film and grime more safely. If you see any structural damage, have that looked at first.
For most exterior jobs, no. The price is agreed upfront before any work starts, and if we miss a spot, we come back and fix it.

Wait until the pine pollen has mostly stopped falling before you wash your house, windows and screened porch. In Mount Pleasant that usually means late spring, once the yellow film stops coming back a day or two after a rain. Wash too early and fresh pollen settles on clean siding within the week.
Most spring pollen is invisible. Pine pollen is not. The Lowcountry is full of pines, and when they release, the grains drift in a yellow-green haze that coats cars, decks, screens and siding across town.
The grains are light and a little waxy. Rain moves them around more than it washes them away. A shower rinses the top layer off your siding and leaves yellow streaks and puddle rings on porches, sills and the bottom courses of siding where the water collects.
Pollen on its own is mostly a cosmetic problem. The bigger issue is what it sits next to. Lowcountry siding already carries mildew, algae and dirt on the shaded sides of the house. A season of pollen and humidity on top of that leaves the north wall greener and the whole house duller by summer.
Pollen season runs from late winter into spring, and the exact start and finish change from year to year with the weather. A warm stretch can start it early. A cold snap can drag it out.
That makes the common mistake easy to understand. The first warm weekend arrives, the house looks yellow, and you book a wash. Two weeks later the pines release another wave and the siding looks the same as before. You paid for a clean house that lasted a few days.
The better plan is to let the season run its course, then wash once and enjoy a clean exterior through summer and fall.
You don’t need a pollen forecast to judge this. Your own driveway tells you.
When two or three of these line up, it’s a good time to schedule.
Different parts of the house collect pollen in different ways. Some can wait. Some are worth a light rinse in the middle of the season.
| Surface | During pollen season | After pollen season |
|---|---|---|
| Siding and trim | Leave it, or rinse with a garden hose if it bothers you | Full soft wash to remove pollen, mildew and algae |
| Windows | Hold off on a professional cleaning | Clean glass, frames and sills once the fall stops |
| Screened porch screens | Gentle hose rinse from inside if airflow suffers | Low-pressure cleaning of screens, frames and floor |
| Porch and patio floors | Sweep or blow off as needed | Wash once, along with the rest of the exterior |
| Gutters | Check after heavy rain for overflow | Check for pollen sludge and debris |
| Outdoor furniture and cushions | Wipe down before use | Deep clean or wash covers |
Once the season ends, a soft wash is the right way to clean siding. A soft wash typically uses low pressure and a cleaning solution that breaks down the organic growth pollen tends to feed, then rinses it away. High pressure on vinyl or painted siding can force water behind the panels, chip paint and leave stripes.
Washing after the pollen also clears off the mildew and algae that built up over the winter. You get one clean that handles the whole spring, not just the yellow layer on top.
For a broader look at seasonal timing, see our guide on when to pressure wash your house.
Windows show pollen worse than anything else. A light film catches the afternoon sun and makes the glass look dirty from the inside.
It’s tempting to clean them first. Resist it. Glass is the surface that gets dirty fastest during the season, and a cleaning in the middle of it rarely lasts. Schedule professional window cleaning after the siding is done, so rinse water and runoff from the house wash don’t spot fresh glass. Sills and tracks deserve attention too, since that’s where pollen collects and turns to sludge.
A screened porch traps pollen. The mesh catches it, the floor collects it, and every breeze shakes it loose again. By late spring the screens can look yellow and block a noticeable amount of airflow.
Screens are delicate. Strong pressure stretches the mesh, pops it out of the spline and tears older screens. A careful porch cleaning usually means low pressure on the screens, a gentle wash of the frames and ceiling, and the floor last so everything that falls is rinsed away.
If the porch is unusable in the middle of the season, a gentle rinse with a garden hose from the inside out will help for a while. Save the full clean for when the pines are done.
The order matters more than the date: house wash first, then the porch, then windows. Each step sends water and debris downward or onto glass, so working top-down and finishing with windows means nothing undoes anything else.

It varies with the weather each year. Pollen generally falls from late winter into spring and tapers off in late spring. The best signal is your own property: when cars, patio furniture and puddles stay free of yellow film for several days, the heavy fall is over.
Rain moves pollen around but rarely removes it. It often leaves yellow streaks on siding and rings where water collects on porches and sills. A proper wash after the season is the only way to get it all off, along with the mildew and algae underneath.
You can rinse it with a garden hose, which is safe and helps between cleanings. High pressure on siding is risky, since it can force water behind panels and damage paint. A soft wash removes pollen and organic growth without that risk.
After. Washing the house sends water and runoff over the glass, so windows should be the last step. Doing it in that order means you only pay for clean windows once.

For most Mount Pleasant homes, soft washing is the safe way to clean siding. It uses low water pressure and a cleaning solution that kills mildew and algae at the root. High pressure belongs on concrete and other hard, flat surfaces. On vinyl, Hardie board, stucco, painted brick and tabby, it can crack, gouge or force water behind the wall.
Soft washing is a low-pressure cleaning method. In a typical soft wash, a technician applies a cleaning solution to the siding, gives it time to work, then rinses at roughly the pressure of a strong garden hose.
The solution does the cleaning. Mildew, algae and the black streaks you see on the shady side of a house are living growth. A detergent built for that job breaks them down and kills the spores, so the siding stays clean longer than it would after a plain water rinse.
Pressure washing works the other way. It relies on force. A narrow, high-pressure stream strips dirt off a surface mechanically. That is exactly what you want on a stained driveway. It is not what you want on the outside walls of your home.
Siding is built to shed rain falling from above. It is not built to hold up against a jet of water aimed at it from below or from the side.
A few things can go wrong:
If you want the longer list of ways a well-meaning wash goes sideways, see our post on common pressure washing mistakes.
Homes around Mount Pleasant use a wide mix of exterior materials, and each one reacts to water and pressure differently. Here is how each should be handled.
| Surface | Method | Why |
|---|---|---|
| Vinyl siding | Soft wash | High pressure can crack panels and push water behind the laps. |
| Hardie board (fiber cement) | Soft wash | The painted finish can be stripped or etched, and water forced into seams can cause swelling at cut edges. |
| Stucco | Soft wash | Stucco is porous and can chip or gouge. Water driven into cracks can get behind the finish. |
| Brick | Soft wash, with care on mortar | Brick is tough, but mortar joints are softer and can erode. Painted brick needs the gentlest approach. |
| Tabby | Soft wash, very gentle | Tabby is a soft mix of lime, sand and oyster shell. High pressure can wear the surface away. |
| Concrete driveways and walkways | Pressure wash | Hard, flat and durable. Force is what lifts embedded dirt and stains. |
Vinyl is a popular siding choice on newer homes. It is durable against weather but not against a pressure washer. Panels can crack, and the lap joints can let water in when sprayed from below. A soft wash removes green algae and dirt evenly and leaves the panels intact.
Fiber cement is strong, but its protection comes from the paint. Aggressive pressure can wear that paint, and water forced into seams and cut edges can lead to swelling and other moisture problems. Low pressure and the right detergent protect the finish you paid for.
Stucco looks solid, but it is porous and holds onto mildew in its texture. High pressure can chip the surface and push water into hairline cracks. A soft wash reaches into the texture with solution instead of force.
Brick can take more than most surfaces, which is why people assume it is fine to blast. The weak point is the mortar between the bricks. Too much pressure can wash out the joints over time. Painted brick needs the same care as any painted surface.
Tabby is part of Lowcountry building history, and it is soft. It should be cleaned gently, with low pressure and patience.
Soft washing is not a replacement for pressure washing. It is the right tool for a different job.
Concrete driveways, sidewalks and other hard surfaces respond well to controlled high pressure. Professionals often use a surface cleaner on flat concrete because it keeps the spray even and helps prevent stripes. For driveways and other concrete, see our pressure washing service. A whole-property clean often calls for both methods: soft wash on the house, pressure on the flatwork.
A professional soft wash is quieter and slower-looking than people expect. There is no roaring stream peeling grime off in strips.
In a typical soft wash, the solution goes on, sits long enough to work, and rinses off clean. A careful crew will also look out for plants and landscaping along the way.
With us, you don’t need to be home for most exterior jobs. You get upfront pricing, so the price is agreed before anyone starts. And if we miss a spot, we come back and fix it.
If you are deciding when to schedule, our guide on when to pressure wash your house covers timing.
You can, but it is not the safest choice. High pressure can crack vinyl panels and push water behind the laps, where it may lead to hidden moisture problems. Soft washing cleans vinyl just as well and kills the algae and mildew instead of only knocking them loose.
Yes. Low pressure protects the painted finish on fiber cement and keeps water out of the seams and cut edges. It is the method generally recommended for Hardie board and similar siding.
On siding, it usually works better. Pressure only removes what it hits, while the cleaning solution in a soft wash treats the growth itself. That tends to keep siding cleaner for longer in a humid climate.
A careful crew protects landscaping before, during and after the wash. Ask any company you hire how they handle plants and beds around the house. It is a fair question and a good sign when they have a clear answer.
If your siding is turning green or gray, a soft wash is the safest way to bring it back. See our soft washing service for details, call (843) 471-0799, or request a quote online. We are fully insured, with a certificate of insurance on request.
You rented or bought a pressure washer hoping for sparkling siding and a spotless driveway, but instead you ended up with gouged wood or peeled paint. These machines may look like oversized squirt guns, yet a few small slip-ups can turn a quick chore into a costly repair bill, leaving many homeowners turning to professional pressure washing services instead.
The good news is that the most common pressure washing mistakes are simple to avoid once you know what to watch for. Mount Pleasant Pressure Washing has seen it all, and we want to help you skip the headaches.
The most common pressure washing mistake comes down to picking the wrong tip for the job. Each pressure washer nozzle changes the angle and intensity of the spray. A narrow tip on a delicate material is a fast track to surface damage.
Here is a quick rundown of the color-coded tips and where they belong:
Always match the tip to the material. If you’re unsure, test the nozzle on a hidden spot first. Following the right pressure washing order also makes a real difference in how evenly your home cleans up.
Skipping prep work leads to pressure washing mistakes that creep up mid-project. Loose furniture, exposed outlets, open windows, and tender landscaping can all suffer when water and debris start flying.
Take a few minutes to sweep the area, cover outlets with tape, close windows tightly, and drape tarps over plants. A quick rinse of nearby foliage with a garden hose washes away any stray detergent.
One of the riskiest pressure washing mistakes is treating these machines like toys. A narrow stream of water at several thousand PSI can slice through skin, and many homeowners forget that until something goes wrong.
Before you pull the trigger, gear up with the basics:
The right protective gear is non-negotiable, and you should never climb a ladder while spraying. Kickback can knock you off balance, so reach for a telescoping extension instead.
How you hold the wand matters just as much as the tip you chose. Spraying head-on drives grime deeper into porous materials, while a slight angle lifts the dirt and pushes it away.
Standing too close concentrates the high-pressure spray onto a tiny area, and that focused force can carve lines into wood or punch through soft vinyl. Keep the wand 12 to 18 inches from the surface and move in smooth, overlapping strokes.
Never aim upward into siding, either. Doing so forces moisture behind the panels and can lead to damaged siding and hidden mold.
Not every surface around your home can handle a high-pressure spray. It’s often best to avoid pressure washing the following materials to prevent damage:
Stick to durable materials like concrete, brick, and fiber cement siding at appropriate settings. When you spot peeling paint or aging caulk, slow down and reach for a softer method.
When the trigger is not engaged, your pressure washer redirects water back through the pump in a closed loop. That water heats up fast, so idling for more than a minute or two can burn out the pump. Most consumer-grade washers lack the ceramic-lined parts to handle prolonged idling.
Avoiding pressure washing mistakes comes down to using the right gear, settings, and nozzles for approved surfaces. If you would rather skip the guesswork, Mount Pleasant Pressure Washing can estimate the time required to pressure wash your property and handle the cleaning for you.

Your home’s exterior takes a beating from dirt and grime, and, at some point, a garden hose is no longer enough to keep surfaces clean. That’s when most homeowners start looking into pressure washing services to restore curb appeal. Picking the wrong service provider can lead to damaged siding or a sloppy result you’ll have to redo.
If you want to choose a pressure washing company that treats your property like its own, you need to know what to look for. Mount Pleasant Pressure Washing has six practical tips to help you decide.
A licensed and insured pressure washing company protects you from financial liability if something goes wrong. Avoiding common pressure washing mistakes starts with hiring a contractor who has the right paperwork in place. Pressurized water can crack windows, strip paint, and even injure workers on a ladder.
Here’s what to confirm before booking a service:
A company that has been cleaning homes for years knows how different surfaces respond to water pressure. Experience and reputation often go hand in hand when you’re trusting someone with your largest investment.
Ask how long the company has served the Charleston area and which surfaces they handle most often. Vinyl siding, wood decks, and other materials all require different techniques.
A seasoned crew can explain their approach without hesitation. If the answers feel rushed or vague, keep looking.
To choose a pressure washing company with an excellent reputation, pay close attention to customer reviews and testimonials. They give you an honest look at what working with a company is actually like. Online feedback often reveals patterns that a sales pitch won’t.
Look for these signs when reading reviews:
The tools and methods a contractor uses make a huge difference in the outcome. Consumer-grade washers from a big-box store can’t deliver the same results as commercial equipment.
Proper equipment and cleaning techniques also reduce the risk of damaging delicate surfaces. Soft washing uses low pressure with specialized solutions to safely clean roofs and siding.
Pressure washing, on the other hand, relies on a higher force to clean concrete, brick, and other durable surfaces. A skilled technician knows when to switch between the two methods.
Safety practices and insurance coverage should never be afterthoughts when hiring an exterior cleaning service. Working at heights, handling chemicals, and operating high-pressure equipment all carry real risks.
A professional crew follows trained protocols to keep your property and their workers safe. If a company can’t clearly explain its safety procedures, that’s a red flag worth taking seriously.
You should also ask whether the company uses biodegradable detergents and how they manage water runoff during the job. A responsible contractor will protect your landscaping by rinsing nearby greenery and shielding sensitive areas.
Cost matters, but the lowest bid is rarely the best deal. Companies that underprice their services often cut corners to make a profit.
Transparent pricing and estimates show you exactly what you’re paying for. A reliable contractor will break down the scope of work, the surfaces they will clean, and the methods they plan to use.
Get quotes from at least three providers before you choose a pressure washing company. Pay attention to what each estimate includes rather than focusing only on the bottom line.
When you choose a pressure washing company, you’re hiring a team that can help protect your property for years to come. At Mount Pleasant Pressure Washing, we bring trained technicians and a customer-first approach to every job.
If you’ve been wondering when to pressure wash your home, our team is happy to walk you through the timing and signs to watch for. We specialize in house washing, roof cleaning, and concrete restoration tailored to the Lowcountry’s climate.
