The Peppers Journal
Guides, seasonal tips, and the hard-won lessons from 600+ Charleston homes. Keep your exterior looking sharp year round.
The Peppers Journal covers everything Lowcountry homeowners need to know about exterior cleaning, from why your driveway turns green so fast to how often you should pressure wash your Charleston house and the right way to soft wash a roof in our humidity. We write from 12+ years of cleaning more than 5,000 homes across Kiawah, Mount Pleasant, Johns Island, and the entire Tri-County area.

Topics fall into a few repeating categories: seasonal guides that walk you through what to clean before spring pollen or after hurricane season, surface-specific tutorials like our soft wash vs. pressure wash breakdown, cost guides such as how often to pressure wash a Charleston house, and comparison posts like why driveways turn green so fast and our year-round seasonal calendar.
Generic national pressure washing advice doesn't hold up in the Lowcountry. Our humidity keeps surfaces damp long enough for algae and mildew to take hold year round, salt air pits metal fixtures and etches glass along Isle of Palms and Sullivan's Island, live-oak canopy drops pollen and leaf debris that jam gutters from Mount Pleasant to James Island, and hurricane season reshapes what's growing on your roof. Every post we publish is written with those local conditions in mind.
We aim for a new post every few weeks, usually tied to a question we just answered on a driveway, a pattern we keep seeing in a neighborhood, or a seasonal shift worth flagging before it costs homeowners money. Every article here comes from real Charleston jobs, not AI-generated filler.

Most of what dulls vinyl siding is living growth, not dirt. Here is how to tell what you have, which cleaner kills it, and whether a pressure washer is safe.
SH stands for sodium hypochlorite, the bleach that does the real work in soft washing. Here is the plain English beginner's guide to mixing it, using it, and staying safe.
Moss, algae, and lichen look similar and matter very differently. Here is how to tell them apart, remove each safely, and keep growth from coming back.
Red, yellow, green, white, and black pressure washer tips explained, plus the safe PSI for siding, wood, concrete, brick, and roofs. Start wide, start low.

Orange rust, black oil, and green algae are three different problems needing three different chemicals. Here is how to tell them apart and remove each one.
Black mold on vinyl siding in Charleston usually isn't mold at all. It's algae, mildew, or artillery fungus spores that love our six months of 80% humidity. You can scrub the surface streaks off with a brush and bleach water, but the stuff growing behind the siding seams won't budge without a proper soft wash.
Most Charleston homeowners ask how often they should pressure wash their house only after the siding has already turned green. The real answer depends on how much oak canopy hangs over your roof, how close you are to the marsh, and whether you'd rather pay $400 every 18 months or $1,200 every four years to repaint. Here's the honest breakdown based on twelve years of cleaning homes from Kiawah to Wagener Terrace.
Patio cleaning in Charleston isn't just dirt. You're scrubbing oak pollen, salt haze from Folly, magnolia sap, and mildew that thrives in 70°F dew points all summer. Most homeowners crank the PSI and strip their pavers instead of killing what actually grew. Here's the chemistry-first approach that keeps outdoor spaces clean past Memorial Day.
Mildew on siding in Charleston shows up every June when dew points stay above 70°F and your north walls never dry between sunset and sunrise. The real problem isn't the humidity reading at noon; it's the film that condenses at 3 a.m. while algae spores feed on spartina pollen and salt haze. I've soft washed hundreds of Lowcountry homes, and the pattern holds from Wagener Terrace to James Island: north walls under oak canopy turn green first, then covered porches, then east-facing walls.
Pool deck cleaning in Charleston means dealing with algae, mildew, and calcium buildup by April if you skipped maintenance last fall. The surface material decides everything: travertine cracks under pressure that stamped concrete laughs off, and pavers need a completely different approach than either one. I've seen homeowners wreck $15,000 travertine decks in Kiawah trying methods that work fine on their driveway.
Every pressure washing company in Mount Pleasant claims 5-star service, but most reviews mention friendliness and price while ignoring the work that actually protects your home. Real quality happens in the 15-minute pre-wash walk, the PSI adjustments for Old Village cedar versus Carolina Park Hardie plank, and the chemical ratios that keep Shem Creek salt mist from undoing everything in four months. Here's what separates cosmetic cleaning from work that lasts.
Pressure washing solar panels voids manufacturer warranties from LG, SunPower, REC, Panasonic, Canadian Solar, and Q CELLS. It damages anti-reflective coatings, cracks cell encapsulants, and forces water past junction box seals. Use soft wash only.
