The Problem
Why do the shaded and north-facing walls on your Mount Pleasant home turn green while the roof grows black streaks?
It is not dirt, and no amount of rinsing will keep it gone. That green film on your siding is algae and mildew, and those dark stains running down your roof are gloeocapsa, a hardy bacteria that feeds on the limestone filler in asphalt shingles. Mount Pleasant is one of the toughest spots in the Lowcountry for both. Shem Creek and Wando River humidity, the salt aerosol that drifts up from the harbor near Patriots Point and the Ravenel Bridge, and the heavy live oak canopy over Old Village lots create shade and moisture that let spores multiply fast. North-facing and tree-shaded walls turn first. The fix is not more pressure. It is chemistry that kills the growth at the root, and that is exactly what soft washing does.
"In Mount Pleasant I can almost always tell which way a wall faces before I read the compass. The north and oak-shaded sides in Old Village and I'On green up months before the sunny sides, and that is a spore problem, not a dirt problem. Soft washing is the only thing that actually keeps it gone."

What Mount Pleasant Does to Your Windows
Creek and river humidity feeds fast mildew growth
Homes near Shem Creek, Pitt Street Bridge, and the Wando River sit in some of the most humid air in the region. That constant moisture is what mildew and algae need to spread across siding and soffits. Soft washing kills the growth at the spore level so it does not just come back after the next rain.
Roof streaks on asphalt shingles
The black stains running down Mount Pleasant roofs are gloeocapsa bacteria, and high pressure would strip granules and void your shingle warranty. Roofs need the low-pressure soft-wash method: detergent does the work, not force, so streaks clear without damaging the shingles.
Coastal siding that pressure would ruin
Hardie plank in Park West and Dunes West, painted brick in I'On, and stucco on custom homes all fail under high pressure, which can force water behind the surface and chip paint. Soft washing cleans these coastal-luxury exteriors gently and evenly, the way they were meant to be cleaned.

Soft Washing Built for Mount Pleasant
Soft washing, not pressure washing, is what your house and roof need
Here is the distinction that matters most in Mount Pleasant. Pressure washing is for hard surfaces: concrete driveways, pavers, and brick walkways that can take real force. You should never point high pressure at siding or a roof. On Hardie plank, painted brick, stucco, cedar, or asphalt shingles, high pressure chips paint, gouges the surface, and can force water behind the cladding where it causes rot and mold. Soft washing is the opposite approach. It uses low pressure, roughly what comes out of a garden hose, paired with biodegradable detergents that do the actual cleaning.
Why soft washing lasts far longer
A pressure wash rinses the surface. Soft washing kills the mold, algae, mildew, and bacteria at the root, so it takes far longer for the growth to return. On a Mount Pleasant home that difference is real: a properly soft-washed Lowcountry exterior stays clean roughly 18 to 24 months, even here where Shem Creek and Wando humidity push algae growth faster than almost anywhere in the Southeast. You are not just paying for a clean house today, you are buying a year and a half or more before you have to think about it again.
Built for Mount Pleasant's coastal-luxury homes
Mount Pleasant runs from the historic-style construction and oak canopy of Old Village and I'On to the newer Hardie plank and custom builds of Park West, Dunes West, and Brickyard Plantation. Every one of those surfaces wants a slightly different chemistry and dwell time, so we match the mix to the material rather than using one blend on everything. Painted brick and stucco get a gentler approach than plank, and heavily shaded north-facing walls get the dwell time the mildew load demands. Before we start we pre-wet and rinse the plants and beds so detergent never sits on your landscaping, and on harbor-side and Wando riverfront homes we finish with a salt-air rinse.
What soft washing costs in Mount Pleasant
There is no flat rate, because a two-story Park West Hardie-plank home is a different job than a single-story I'On brick home with heavy oak shade. Price is driven by the size and number of stories, the siding type, whether you add the roof, how complex the landscaping is, and whether the home needs a salt-air rinse. We are owner-operated and based on Johns Island, about 35 minutes out, and we give free same-day quotes with usually same-week scheduling. Every job ends with a post-wash walk-through, and the fastest way to a real number is to send us the address.
We clean windows for homes near Patriots Point, Pitt Street Bridge, Shem Creek, Ravenel Bridge, and every neighborhood in between.

Questions
Soft Washing Questions Mount Pleasant Homeowners Ask
How much does soft washing cost in Mount Pleasant?
There is no single flat price, because it depends on your home. The main factors are the square footage and number of stories, the siding type (Hardie plank, painted brick, and stucco each wash differently), whether you include the roof, how complex your landscaping is, and whether your home near the harbor or Wando needs a salt-air rinse. We give free same-day quotes, so the quickest way to an exact number is to send us your Mount Pleasant address.
How often should I soft wash my Mount Pleasant home?
A properly soft-washed home in Mount Pleasant stays clean roughly 18 to 24 months, which is far longer than a pressure rinse lasts because soft washing kills the algae and mildew at the root rather than just rinsing it off. Homes with heavy oak shade in Old Village or I'On, or those close to Shem Creek and the Wando, sit at the shorter end of that range because the humidity and shade grow spores faster.
Is soft washing safe for my roof and siding?
Yes, and it is the only method you should use on them. Soft washing runs at roughly garden-hose pressure, well under 500 PSI, so it will not chip paint, gouge Hardie plank or stucco, or force water behind your siding the way high pressure can. On an asphalt-shingle roof it clears the black gloeocapsa streaks using detergent rather than force, so it does not strip granules or risk your shingle warranty.
What is the difference between soft washing and pressure washing?
Pressure washing uses high force and is right for hard surfaces like concrete driveways, pavers, and brick walkways. Soft washing uses low pressure plus biodegradable detergents and is the correct method for everything on your house exterior: siding, soffits, screened porches, painted brick, and the roof. In Mount Pleasant we soft wash the home and roof and reserve high pressure for the flatwork. A separate service covers the driveway and hardscape.
Will soft washing hurt the plants around my Mount Pleasant home?
No. We pre-wet the plants and beds around the work area before we start and rinse them again afterward, and we use biodegradable detergents. This matters on the landscaped lots common in I'On, Park West, and Dunes West, where mature plantings sit right against the house. Protecting your landscaping is part of every soft-wash job, not an add-on.
