Soft Washing vs. Pressure Washing: Which Does Your South Riding Home Need?
What soft washing is
Soft washing is a gentle ~200 PSI (or less) method that applies an algaecide solution to kill algae, mold, and mildew, followed by a low-pressure rinse. It's ideal for siding, roofs, and other delicate surfaces.
What pressure washing is
Pressure washing uses high pressure (2,000-3,500 PSI) with a surface cleaner to blast away dirt and stains from tough concrete like driveways, walkways, and curbs.
Which does your South Riding home need?
Most homes need soft washing on siding and roof, and pressure washing on concrete. South Riding's mature tree cover means more shade and faster algae growth on siding, making soft washing especially important.
What it typically costs
Most South Riding house washes run $250-$600 depending on size and buildup. Call (571) 291-5206 for a free quote.
