Pressure Washing in Dover, NH

From historic homes downtown to newer neighborhoods, we soft wash Dover exteriors back to clean.

Dover mixes old mill-era homes downtown with newer neighborhoods spreading out from the Cochecho River, and both collect the same New England grime: green algae on siding, black streaks on roofs, and moss creeping across shaded driveways. Black Diamond cleans it all, at the pressure each surface can handle.

Full exterior cleaning

House washing, roof soft washing, driveway and concrete cleaning, decks and fences, and pool decks across Dover. The damp air off the river and the heavy tree cover in a lot of Dover neighborhoods make algae and mildew a regular problem, and treating the growth rather than just rinsing it is what keeps it gone longer.

Right method for the home

Older homes near downtown need the gentle soft wash touch, while newer vinyl-sided houses clean up fast. We match the approach to the house instead of blasting everything the same way.
