Which method does your surface actually need?
The right answer depends on the surface. Hard, durable surfaces like concrete sidewalks, parking lots, dumpster pads, and loading docks can take high-pressure washing at 2,000 to 4,000 PSI, which blasts away gum, oil, tire marks, and embedded grime. Delicate surfaces like vinyl siding, painted brick, stucco, awnings, and signage need soft washing — low pressure under 500 PSI paired with biodegradable detergents that kill mold and algae at the root without cracking finishes or forcing water behind panels.
Charleston's humid, coastal climate makes exterior cleaning a maintenance issue, not just a cosmetic one. Mildew creeps up siding, algae darkens north-facing walls, and organic growth makes walkways slick and unsafe. Left unchecked, that buildup shortens the life of paint, mortar, and concrete and quietly tells customers a business has stopped paying attention.
Our crews arrive with self-contained rigs that carry their own water, so we never tap your building supply. We protect landscaping, adjust pressure and detergent for each surface, and manage runoff responsibly. From a single storefront to an entire shopping-center exterior, we build the schedule around your operating hours.
