A 60-second look at our crew tackling real concrete cleaning jobs across the Lowcountry.
The Problem
Take a close look at a Charleston driveway that has not been cleaned in two years and you will see more than dirt. The gray-green fuzz along the expansion joints is algae. The black discoloration in the shaded portions is a biofilm of mildew and fungal growth that actively degrades the surface of the concrete. The orange-red streaks near flower beds are iron oxidation from the Lowcountry's red-clay subsoil leaching up through porous concrete. None of this is cosmetic. Algae and biofilm hold moisture against the concrete, accelerate freeze-thaw damage, and create surfaces so slick that falls become a liability — especially around pool decks and back patios. Oil stains from vehicles sink into the pores within 48 hours and become permanent without the right emulsifiers. Tannin stains from live oak droppings bond so tightly that most homeowners assume they will need to resurface — but the right chemistry brings the concrete back. Properly cleaned concrete in the Lowcountry needs surface-cleaner pressure of around 3,000 PSI on flat slabs, paired with the correct chemistry: degreaser pre-treatment for oil, oxalic acid for rust, sodium hypochlorite for biological growth. Anything less and the surface looks better for two months before the algae returns. The single biggest mistake homeowners make is renting a 4,000 PSI gas washer and attacking the driveway with a narrow-tip wand. The streaking pattern that produces is permanent until the concrete is professionally surface-cleaned to even out the depth of the wash.
"A professionally cleaned Charleston driveway adds an estimated 3-5% to curb-appeal-driven home valuations — it is the single cheapest pre-listing exterior upgrade available."
The Peppers Solution
Paver stairs collect moss in the joints and tannin stains from oak debris. Our surface cleaner attachment scrubbed every paver evenly without dislodging joint sand on this Charleston entryway.
Old Charleston brick holds moss like a sponge, rain rebuilds it within weeks of cleaning. Our soft-wash with low-pressure rinse cleared this entry without etching the historic mortar joints.
Oak leaves and pine straw left tannin staining baked into this Mount Pleasant paver staircase. Pre-treatment plus surface-cleaner pass lifted both the surface debris and the embedded stain.

Why Peppers
Concrete in the Charleston area takes more abuse than in almost any other climate in the country. Between year-round humidity that lets mold and algae grow continuously, red-clay subsoil that pushes iron stains up through the slab, live oak tannin drops that bond to the surface within days, and the occasional freeze-thaw cycle that expands every crack, our concrete surfaces need more help than a quick rinse.
Concrete surfaces — patios, pool decks, walkways, sidewalks, parking pads — handle pressure washing (and power washing, which is the same service performed with heated water) better than almost any other exterior material. The density and hardness of poured concrete mean we can use full-pressure surface cleaning without the risk of damage that comes with siding or roofing. For driveways specifically — the largest single piece of concrete on most properties and the most exposed to oil staining and street-side mildew — we maintain a separate driveway cleaning service with its own dedicated process for oil stain pre-treatment, curbside detail, and HOA covenant timing.
You've probably seen patios and pool decks that came out looking like a zebra — uneven strips of clean and dirty running parallel to each other. That's what happens when someone tries to clean concrete with a handheld wand. Pressure drops off rapidly with distance from the surface, so a few inches of variation produces visible striping that won't come out without a second full cleaning. The only reliable way to clean concrete evenly is a dedicated surface cleaner — a rotating spinner bar enclosed in a shroud that maintains consistent pressure across every square inch.
Every concrete cleaning we do starts with a surface cleaner pass. After that we detail edges, corners, and transitions with a wand. Then we pre-treat oil stains and tannin marks with the right chemistry before doing a final rinse. A proper concrete cleaning takes longer than most homeowners expect — that's the difference between a rushed handyman job and a real clean.
Tannin marks deserve a specific note. If your concrete pool deck or patio sits next to an IPE or other tropical hardwood deck, you've probably seen brown streaks running off the wood onto the concrete after every heavy rain. That's tannin bleed — natural oils from the hardwood. We can remove existing tannin staining as part of a concrete cleaning visit, and we coordinate with our IPE deck cleaning service to prevent it on the next round by tarping the concrete during deck washing.
If you have concrete pavers, brick pavers, or stamped concrete, high pressure is not your friend. Paver installations rely on polymeric sand packed into the joints to lock the pavers in place and prevent weed growth. Hit those joints with 3,500 PSI and the sand blows straight out — within months you'll have pavers shifting, tripping hazards developing, and weeds establishing in the open joints.
For pavers we use lower pressure combined with surfactant chemistry, and we can re-sand joints after cleaning if needed. Stamped concrete is even more delicate — high pressure will actively erode the decorative finish and strip the color seal. We treat both with the care they require.
Oil stains are the most common concrete problem in Charleston driveways, and also the most misunderstood. Pressure alone will not remove oil that has soaked into the porous top layer of concrete — you need an emulsifying degreaser that breaks down the oil and lifts it back out of the pores. We apply a commercial-grade emulsifier, let it dwell, agitate if needed, and then rinse with hot water where possible. Older oil stains often fade significantly but rarely disappear completely — that's a fact of concrete, not a limitation of the cleaning.
Rust stains from irrigation systems, fertilizer, or iron in the soil take a dedicated rust remover applied separately. Tannin stains from live oak and pecan drops need an oxalic acid treatment. We handle all three as add-ons or as part of a full concrete clean — call for pricing.

Trusted by Hundreds
Our neighbor scheduled Peppers about 6 months ago and we were very impressed with their results so we scheduled them ourselves. We got our entire house cleaned as well as power washing the driveway. The results were AMAZING! Peppers far exceeded our expectations. The house is cleaner than it has ever been.

Questions
Straight answers to the questions Charleston homeowners ask most.
Driveway pressure washing pricing depends on total square footage, surface condition, and the number of stains requiring special treatment. A single-car driveway is a quicker job than a large custom home driveway in Daniel Island or Kiawah, and heavily stained concrete takes more time and chemistry than a routine maintenance clean. Oil stain treatment, rust removal, and optional post-clean sealer are priced separately. We bundle driveway and walkway cleaning when done together for a discount, and full concrete package pricing is lower than booking each surface individually. Call 843-480-8113 or request a free quote online for exact pricing.
Honest answer: only if the stain is fresh. Oil that has set on the concrete for under 48 hours usually comes out completely with our emulsifying degreaser treatment. Once the oil has been sitting for longer than 48 hours it has penetrated deep into the pores, and we cannot completely remove it — but we can almost always make it look 100% better. We'll always be honest about what we think we can achieve on a specific stain before we start. Oil treatment is an add-on to standard driveway cleaning.
Most Charleston driveways benefit from cleaning every 12-18 months. Driveways under heavy tree canopy — especially near live oaks or pines — often need annual cleaning to prevent tannin stains and algae from becoming permanent. If you can see green discoloration in the expansion joints, it's time. Regular cleaning prevents the staining from becoming permanent and keeps the concrete from getting slippery during Charleston's wet months. Annual maintenance is significantly cheaper than letting a driveway reach the point of needing resurfacing.
We offer optional penetrating concrete sealer application as an add-on service after cleaning. A quality penetrating sealer locks in the clean look for 2-3 years, makes future maintenance cleaning much easier, and provides meaningful protection against oil, rust, and tannin staining. Sealer pricing depends on total square footage, the product selected, and coverage requirements. We only apply sealer on fully dry concrete — usually the day after the wash. Contact us for a free estimate tailored to your property.
High pressure absolutely can damage pavers — specifically by blasting the polymeric sand out of the joints that holds the installation together. That's why we never use full pressure on paver installations. We use lower-pressure surface cleaner settings combined with surfactant chemistry that kills biological growth without displacing joint sand. If we see that joint sand has already washed out from rain or previous aggressive cleaning, we can re-sand the joints after cleaning as an add-on.
Yes — rust stains from irrigation systems, leaking fertilizer, or iron-rich soil respond well to a dedicated rust-remover treatment. It's a separate application from standard pressure washing because it uses oxalic acid chemistry rather than general degreaser. Most rust stains come out completely or fade to barely visible. Deep-set rust that has been on the concrete for years may leave a faint ghost but dramatically improve. Rust treatment is priced per affected area.
On a typical warm Charleston day with sunshine and breeze, concrete is walkable within 1-2 hours of cleaning and fully dry within 4-6 hours. On humid overcast days or in shaded areas, it can take up to 24 hours to fully dry through. If you're planning to apply sealer, we schedule that for the following day to make sure the concrete is completely dry. Vehicle traffic is fine the same day — concrete does not need cure time after cleaning the way it does after being poured.
Pool decks are one of our most-requested services in Charleston — especially in Mount Pleasant, Daniel Island, and Kiawah. Pool deck cleaning is a careful job because the surfaces are often coated (Kool Deck, acrylic overlays, pebble surfaces) and the chemistry has to be matched so we don't damage the coating. We use softer pressure, surfactant-heavy chemistry, and always rinse thoroughly to avoid introducing cleaning agents to the pool itself. Pool deck pricing depends on total square footage, surface type, and condition. Call 843-480-8113 or request a free quote online for exact pricing.

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.
