Pressure Washing in Lexington SC: How We Remove Red Clay Stains, Algae, and Years of Grime

We clean every hard and soft exterior surface on Lexington residential and commercial properties. Driveways, sidewalks, patios, and garage floors get pressure washed with commercial surface cleaners for streak-free results. House exteriors, roofs, gutters, and painted surfaces get our soft wash treatment -- low pressure with professional detergents that kill biological growth at the root level. Decks and fences are cleaned at pressures matched to their material -- wood, composite, vinyl, and aluminum each have different tolerance levels. We carry both cold and hot water capability. Hot water is essential for grease removal on commercial surfaces and restaurant pads.

South Lexington (Pebble Creek, Platt Springs, Cedar Crest): typical suburban lots with concrete driveways showing red clay tracking. These are our most common driveway jobs -- 45-90 minutes per property. Lake Murray corridor (Harbour Watch, Windward Point, Old Cherokee, Saluda Pointe): lakefront properties with accelerated algae growth on every surface. Decks, docks, and retaining walls need semi-annual cleaning. Highway 378 / White Knoll area: newer subdivisions with young concrete that stains more easily in the first 5 years. Old Town Lexington / downtown: smaller lots with more hardscape -- sidewalks, stoops, and brick surfaces that need careful pressure control. Pine Ridge and rural-adjacent: larger properties where driveway length adds to the scope. Many have gravel-to-concrete transitions that trap clay at the edge.

Red clay staining is the number one pressure washing challenge in Lexington. Clay tracked onto driveways, splashed onto foundations, and ground into sidewalks leaves an orange-brown discoloration that regular rain does not remove. Our process uses a pre-treatment solution that breaks the iron oxide bond before pressure washing, followed by a post-treatment rinse. Standard pressure washing alone pushes the stain deeper into porous concrete -- the chemistry matters as much as the pressure. We use oxalic acid-based treatments specifically formulated for iron oxide stains. After treatment, we surface-clean the entire area for uniform results. Red clay pre-treatment adds $50-$100 to a standard driveway job depending on severity.

Most Lexington house exteriors are vinyl siding, painted wood, or fiber cement -- all surfaces that should never see high pressure. Our soft wash system applies a sodium hypochlorite blend at under 500 PSI that kills algae, mildew, and mold at the root level. The results last 2-3x longer than pressure washing because we're killing the growth rather than just blasting it off the surface. We pre-wet all landscaping within 10 feet and post-rinse with a plant-safe neutralizer. North-facing walls in Lexington are the worst for biological growth -- some homes need the north side treated twice per year even when the rest of the house only needs annual cleaning. Two-story homes require specialized equipment and add $100-$200 to the base price.

Homes along Lake Murray deal with higher humidity and faster biological growth than inland Lexington properties. Lakefront decks accumulate green algae within 3-4 months of the last cleaning. Docks and seawalls develop slippery biofilm that is both unsightly and a safety hazard. We clean these surfaces with methods and chemicals that are safe for the waterway -- no sodium hypochlorite runoff into the lake. We use hydrogen peroxide-based cleaners for dock surfaces. Many Lake Murray homeowners schedule semi-annual cleaning (spring before boating season and fall after pollen/leaf season) to keep outdoor living spaces usable year-round. Boat ramp cleaning is available for HOAs and private ramps.

Wood decks in Lexington take a beating from UV, humidity, and biological growth. Our deck cleaning process starts with a wood-safe detergent applied at low pressure, followed by a rinse that removes the gray oxidized layer. After cleaning, we apply a wood brightener (oxalic acid) that restores the natural wood color and opens the grain for stain penetration. If the deck needs re-staining, cleaning and brightening are essential prep steps -- stain applied over dirty or gray wood won't penetrate or last. Composite decks (Trex, TimberTech) need a different approach -- we use non-bleach cleaners at moderate pressure to avoid voiding the manufacturer warranty. Most Lexington decks need cleaning annually and re-staining every 2-3 years.

Spring (March-April) is peak season -- book in February or March for April-May availability. This is when 60% of our residential work happens. Fall (September-November) is less busy and a good time for a pre-holiday property refresh before family visits. Summer works well for concrete-only jobs but soft washing is harder to schedule because heat makes chemicals flash-dry. Winter cleaning is available on dry days above 40 degrees -- concrete pressure washing works fine year-round. Emergency cleanup after storms or construction is available with short notice. We typically book 1-2 weeks out during spring peak and can often accommodate same-week scheduling in other seasons.
