Exterior Mold & Mildew Removal for Vinyl Siding is one of the jobs we do most often in Saint Clair, MO. Typical jobs cost $250-$700, and you approve the price before we begin. For vinyl siding, that means soft wash.

Cleaning solution: A diluted sodium hypochlorite (house wash) mix with a surfactant, applied low and rinsed thoroughly.
What to know about cleaning vinyl siding
Vinyl is the most common siding in the U.S. and cleans up well, but the panels overlap. Water driven upward under the laps can soak the sheathing behind them, so siding is rinsed at a downward angle and never blasted from below.
Avoid: High pressure aimed up under the panel laps, and hot water on dark-colored vinyl, which can warp.
How often: Every 1-2 years, more often on shaded north walls.
