Preferred Services Group provides commercial soft washing in Charleston, SC for vinyl siding, stucco, EIFS, brick, painted surfaces, and roofs. Soft washing kills the organism at the root, providing longer-lasting results than pressure washing alone. Call (843) 478-2114.
Cleaning That's Gentle on Surfaces, Tough on Mildew
High pressure damages delicate exterior surfaces — and Charleston's humid climate means algae and mildew come back fast on roofs, EIFS, stucco, and painted siding. Soft washing solves both problems by combining low pressure (around the same as a garden hose) with biodegradable cleaning chemistry that kills mold and algae at the root.
Results last 3–5x longer than pressure washing alone, and there's no risk of etching siding, stripping paint, or driving water under stucco.
