The Problem
Why do the north-facing walls and the roof on your Sullivan's Island home turn green and black between Station 22 and Station 30?
Sullivan's Island sits in full Atlantic salt aerosol, and the maritime forest oak canopy that shades so many yards near Station 22, Station 26, and Station 30 traps roughly 80% humidity long after the last rain. That combination feeds some of the fastest algae and mildew growth in the Southeast. Shaded and north-facing cedar shake walls turn green first, and asphalt shingle roofs grow the black gloeocapsa streaks you can spot from Middle Street. The mistake most homeowners (and some crews) make is reaching for high pressure. On siding, shake, and a shingle roof, high pressure strips paint, splinters wood, and forces salt water behind the surface where it does real damage. The correct method is soft washing: low pressure that lets the detergent do the work.
"On Sullivan's Island the shaded, oak-canopy side of a house greens over months before the sunny side ever shows it, and I have watched crews try to blast that off cedar shake with a pressure washer. That is exactly how you strip original paint and drive salt water behind the shake. These homes need soft washing, not pressure."
The Peppers Solution
How We Get Your Sullivans Island Windows Truly Clean
- Roughly garden-hose pressure (under about 500 PSI) with biodegradable, sodium-hypochlorite-based cleaners that kill mold, algae, and mildew at the root on cedar shake, painted siding, and shingle roofs.
- Chemistry and dwell time matched to each surface, with a test spot on the century-old, original-paint homes that define the island before any full wash.
- Salt-air rinse for full Atlantic-facing properties near Fort Moultrie and the Sullivan's Island Lighthouse, so salt does not sit in the shake and hardware.
- Landscaping pre-wet and rinsed to protect the maritime forest plantings and live oaks that shade island yards.
- A post-wash walk-through, plus careful scheduling around a small community, beach access, and neighbor privacy.

What Sullivans Island Does to Your Windows
Cedar shake and century-old original paint
Many Sullivan's Island homes are 100+ years old with cedar shake and hand-hewn trim carrying original paint. High pressure splinters shake and blows paint off. Soft washing cleans the algae and mildew at low pressure without touching the finish, which is why it is the only safe method here.
Full Atlantic salt aerosol
Homes facing the beach near Fort Moultrie take constant salt spray that both accelerates mildew and settles into shake and hardware. Soft washing kills the growth at the root and pairs with a salt-air rinse so the exterior stays clean for the full 18 to 24 months instead of a few weeks.
Maritime forest oak canopy humidity
The interior of the island near Station 26 and Station 30 sits under dense live oak canopy that holds humidity and keeps shaded walls and shingle roofs damp. That is prime algae and gloeocapsa territory, and low-pressure soft washing is what actually clears a shaded roof without damaging the shingles.

Soft Washing Built for Sullivans Island
Soft washing, not pressure washing, for your Sullivan's Island house and roof
Here is the distinction that matters. Pressure washing is for hard surfaces: concrete driveways, pavers, and brick walkways. Your house exterior and your roof are a different story. Soft washing uses low pressure, roughly garden-hose strength (under about 500 PSI), paired with specialized biodegradable detergents. Those cleaners kill mold, algae, mildew, and bacteria at the root instead of blasting the surface. On Sullivan's Island, where so many homes wear cedar shake and original paint, that difference is the whole game. High pressure on siding or a roof strips finish, splinters wood, and forces salt-laden water behind the surface. Soft washing does not.
Why the island's exterior grows algae so fast
Sullivan's Island combines three things that feed growth: full Atlantic salt aerosol, roughly 80% humidity, and a dense maritime forest oak canopy that shades yards from Station 22 through Station 30. North-facing and shaded cedar shake walls turn green first. Asphalt shingle roofs grow black gloeocapsa streaks. Salt spray off the beach near Fort Moultrie and the Sullivan's Island Lighthouse accelerates all of it. A quick rinse just knocks the surface color off for a couple of weeks. Killing the spores is what keeps it gone.
The right method for every surface on the home
Soft washing is the correct approach for the surfaces high pressure would ruin: cedar and wood shake, vinyl and Hardie plank siding, stucco, painted brick, soffits and eaves, screened porches, and asphalt-shingle roofs. Those cover almost the entire exterior of a Sullivan's Island beach home. We match chemistry and dwell time to each surface, and because many of these houses are genuinely historic, we test-spot original-paint and pre-1940s homes before any full wash. Landscaping gets pre-wet and rinsed so the live oaks and maritime plantings are protected.
How long it lasts, and how easy it is to schedule
Because soft washing kills algae and mildew at the root, results last far longer, roughly 18 to 24 months on a Lowcountry home. Full Atlantic-facing Sullivan's homes sit at the more aggressive end, so we recommend a salt-air rinse in between, while oak-shaded homes near Station 26 and Station 30 track closer to the longer end. Pepper's is owner-operated and fully insured, based on Johns Island about 40 minutes away. We schedule around island events, summer beach access, and neighbor privacy, with same-day quotes and usually same-week scheduling. Reach out for a free quote on your Sullivan's Island home.

Questions
Soft Washing Questions Sullivans Island Homeowners Ask
How much does soft washing cost on Sullivan's Island?
There is no flat rate, because a few things drive the price: the size and number of stories of the home, the siding type (cedar shake and original paint on a century-old home take more care than vinyl), whether you include the roof, how complex the landscaping is around the house, and whether you add a salt-air rinse for a full Atlantic-facing property. The best way to get a real number is a free quote. We can usually give you one the same day.
How often should I have my Sullivan's Island home soft washed?
A properly soft-washed Lowcountry home stays clean roughly 18 to 24 months, because the method kills algae and mildew at the root instead of just rinsing it off. On Sullivan's Island, full Atlantic salt exposure near Fort Moultrie pushes homes toward the more frequent end, and we recommend a salt-air rinse in between. Interior homes shaded by the maritime forest oak canopy near Station 26 and Station 30 often stretch closer to the longer end of that range.
Is soft washing safe for my cedar shake, siding, and shingle roof?
Yes, and it is the only method we would use on those surfaces. Soft washing runs at roughly garden-hose pressure (under about 500 PSI), so it never strips paint, splinters cedar shake, or lifts shingles the way high pressure does. The biodegradable detergents do the cleaning, and on Sullivan's Island's original-paint and pre-1940s homes we test-spot first. High pressure is only for hard surfaces like driveways and walkways, never your house or roof.
Can you soft wash a home in full Atlantic salt spray near Fort Moultrie?
Yes. Beach-facing homes near Fort Moultrie and the Sullivan's Island Lighthouse take constant salt aerosol that both speeds up mildew and settles into the shake and hardware. Our method kills the growth at the root and pairs it with a salt-air rinse so the exterior stays clean instead of picking up salt-driven grime again within weeks. We also protect landscaping with a pre-wet and rinse.
Do you work carefully around the historic homes and small-community feel of Sullivan's Island?
We do. Many Sullivan's Island homes are 100+ years old, and we treat them with the same care we give historic downtown Charleston: gentler chemistry, test-spotting original paint and shake, and careful landscape protection. Because the island is a small community, we schedule around island events, summer beach access, and neighbor privacy. Send us the window that works and we will fit it.
