Low pressure for your siding and roof. Real results you can see from the street.
Spartan Soft Wash provides soft washing in Mount Pleasant for homeowners who want a clean house without damaged siding. Between the Lowcountry humidity, salt air off the harbor and the shade from live oaks, mildew and algae grow fast here, and they come right back when they are only blasted off. Our low-pressure soft wash kills that growth at the root, so your siding, trim and roof come clean and stay clean longer, with nothing stripped, etched or forced behind the panels.
Mount Pleasant is one of the toughest places in the Lowcountry to keep a house clean. Moisture off Charleston Harbor, Shem Creek and the marshes along the Wando keeps siding damp for hours after sunrise, and the salt in that air gives algae and mildew something to hold on to. Add the deep shade from live oaks and you get the green film that shows up first on north-facing walls, under eaves and along the bottom of porches.
Roofs take the same beating. The black streaks running down so many Mount Pleasant roofs are Gloeocapsa magma, an algae that feeds on the limestone filler in asphalt shingles. Left alone, it holds moisture on the roof and shortens the life of the shingles. Spring brings a second wave: the yellow-green pollen that coats every surface in March and April and gives mildew a head start for the summer.
Appearance matters here too. Many Mount Pleasant neighborhoods have architectural standards for exterior upkeep, and a soft wash is the quickest way to bring a house back in line before an inspection, a listing or a family event. We regularly handle jobs for homeowners who have received an HOA exterior-maintenance notice, and we can schedule around your deadline.
We soft wash homes across Mount Pleasant in the 29464 and 29466 zip codes, including:
Both clean the outside of a house, but they work in opposite ways. Pressure washing relies on force. Soft washing relies on a cleaning solution that does the work, applied at about the pressure of a garden hose. Here is how they compare:
| Soft washing | Pressure washing | |
|---|---|---|
| Pressure | Low, about garden-hose level | High |
| Best for | Siding, roofs, stucco, painted wood, screens | Concrete, pavers, driveways |
| How it cleans | Solution kills mold, algae and mildew | Force strips the surface |
| Results last | Longer, because the growth is killed | Shorter on siding |
Pressure strips. Soft wash kills the growth. That is why we soft wash siding and roofs and save real pressure for concrete, where it belongs. See how we choose the right method for each surface.
Vinyl, Hardie and other fiber cement, stucco, brick and painted wood siding, along with soffits, fascia and trim. We clean the whole exterior without stripping paint or forcing water behind the panels. More about house washing.
We remove the black streaks from asphalt shingle roofs and clean metal roofs with a low-pressure treatment that kills the algae instead of scrubbing the shingles. More about roof cleaning.
Screens, frames and the ceilings above them collect pollen, cobwebs and mildew. A gentle soft wash brightens the whole space without tearing screens or bending frames.
Wood and vinyl fences go green fast in the shade. We clean them at low pressure so wood is not furred or splintered.
Amenity centers, clubhouses, common-area buildings and storefronts, with after-hours and weekend scheduling, recurring service contracts and pricing across multiple properties. More about commercial washing.
Pair it with driveway cleaning or gutter cleaning on the same visit.
Half a day. You don't need to be home.
“Spartan Softwash blew me away!! Getting a quote and appointment was seamless. Communication with them was easy. They let you know when they are on the way. You can even track their arrival with the software they use. The time they take took to protect my home and plants was like I have never seen before. They weren’t the cheapest but they were worth the extra money. Thank you for taking care of my home!!”
“Spartan did an outstanding job on my house. From start to finish, they were professional, punctual, and paid attention to every detail. They took the time to explain the process, showed up when they said they would, and the results exceeded my expectations. My home looks like new again—the siding, driveway, walkways, and other surfaces came out incredibly clean. It’s amazing what a difference a quality power washing makes. If you’re looking for a company that’s reliable, takes pride in their work, and delivers excellent results, I highly recommend Spartan. I’ll definitely be using them again in the future!”
“The team at Spartan did an amazing job pressure washing our home. Attention to detail was great and they took their time to get everything right. They keep our home looking new year-round.”
Every house is different, so the price depends on a few things:
Soft washing in Mount Pleasant starts at $350, and the final price depends mostly on the size of the house.
The easiest way to know is to check: get your exact price online in about a minute. There's no sales visit and no obligation.
For most Mount Pleasant homes we recommend a soft wash every 12 to 18 months. Shaded north sides, homes on the marsh and houses under live oaks sit at the short end of that range.
We soak plants and beds with fresh water before we start and rinse them again when we finish. We ask that pets stay inside until the surfaces have been rinsed, and you can let them back out as soon as we are done.
For siding and roofs, yes. Algae and mildew hold moisture against the surface, stain paint and shorten the life of shingles. A soft wash removes the growth at the root without the damage high pressure can cause, so you protect the finish you already paid for and the house stays clean longer between washes.
Per visit, the two usually cost about the same for the same size house. The difference is what you get: pressure washing can strip paint, etch soft wood and drive water behind siding, and the growth comes back sooner because it was never killed. Over a few years, soft washing typically costs less because you wash less often.
Yes. Roof soft washing never uses a pressure washer on the shingles. The cleaning solution is applied at low pressure, it kills the Gloeocapsa magma algae that causes black streaks, and the stains fade away with the next few rains. The granules that protect your shingles stay where they belong.
No. We need access to an outside water spigot and your windows and doors closed. Most homes take about half a day, and we send before and after photos when we are finished.
Longer than a pressure wash, because the mold, algae and mildew are killed rather than knocked loose. How long depends on shade, moisture and how close the house is to the marsh or the harbor. Roofs typically stay clean for years after a proper soft wash.
Yes. We clean common-area buildings, amenity centers, fences and multi-home properties, with after-hours and weekend scheduling so residents are not disrupted, and we can set up recurring service across multiple properties.
