Pressure Washing in Rochester, NH

Homes and businesses across the Lilac City, soft washed back to clean at the right pressure.

Rochester spreads across a lot of ground, from downtown and the Gonic and East Rochester villages to newer subdivisions and commercial strips. All of it grows the same New England algae and mildew on siding, roofs, and concrete. Black Diamond cleans homes and businesses across the Lilac City with soft washing that lasts.

Residential and commercial

House washing, roof soft washing, driveway and concrete cleaning, decks and fences, and pool decks for Rochester homes, plus storefront and building washing for local businesses. Whatever the surface, we clean it at the pressure it can safely take.

Growth treated, not just rinsed

The reason a clean lasts is treating the algae and mildew at the root instead of blasting it off the surface. That is the difference between a wash that holds for years and one that greens back up by next season.
