House Washing in Matthews, NC

House washing in Matthews is mostly a vinyl-siding story — the established 90s and early-2000s subdivisions like Brightmoor, Stevens Mill, and Matthews Plantation are predominantly vinyl ranch and 2-story homes, with scattered brick in older Crews Road sections. Vinyl is one of the surfaces that high pressure damages most reliably, which is why every house wash we run in Matthews is a low-pressure soft wash under 1,000 PSI.

The issue we see most here is age. Twenty to thirty years of Piedmont humidity has built up a deep biofilm of mildew, algae, and oxidized chalking on a lot of these homes — the kind that doesn't come off with a garden hose and definitely doesn't come off with pressure alone. Sodium hypochlorite with the right surfactant package is what actually kills the organic growth at the root and rinses cleanly without streaking.
