House & Siding Soft Wash in Greater Sacramento

Soft washing applies a cleaning solution at low pressure, lets it dwell, and then rinses gently. The solution — not brute force — breaks down dirt and kills the organic growth at its root. That matters: rather than just blasting the green off the surface, soft washing treats the living algae and mildew so it sheds over the following three to four weeks and stays gone far longer than a pressure rinse ever would.

High pressure cracks stucco, splinters wood, forces water behind siding, and strips paint. Manufacturers and painters both warn against it. PROSPR uses pressure low enough to be safe on the most delicate finishes, which is why soft washing is the correct method for any vertical home surface — siding, stucco, EIFS, painted wood, and trim.

Expect the result to keep improving for a few weeks after we leave. Because we are killing growth at the root, some staining continues to fade as the dead organic matter weathers off — that is the treatment working as designed, not an incomplete job.

Homes with north-facing walls that go green, stucco streaked under the eaves, or that chalky, dingy film that a hose just smears around. If your home looks dirty in the shade and you are afraid to pressure-wash it yourself, soft washing is the answer.
