What pressure washing costs in Dover, NH
Dover's housing stock ranges from tight-lot downtown colonials near Central Avenue to larger newer builds in neighborhoods like Garrison Road and Whittier Falls. A typical house wash runs $300–$550. Roof washing on a standard Dover colonial starts at $400 and varies by size and growth. Gutter cleaning for most Dover homes runs $175–$325. All estimates are free and prices are locked in before we start.
Dover's exterior cleaning challenges
As NH's oldest city, Dover has a significant stock of older homes — many with wood clapboard siding, older asphalt shingles, and mature trees that shade large portions of the exterior. Shaded north-facing walls and roofs accumulate mold, mildew, and algae particularly fast in Dover's humid inland climate. The Cochecho River corridor and neighborhoods near Bellamy River frequently see heavy organic growth on home exteriors. Soft washing removes this buildup safely without the high pressure that can damage older wood and roofing materials.
When to schedule in Dover
Spring is the most popular time for Dover homeowners to schedule exterior cleaning after the long NH winter. We typically have availability through late May, but April dates fill quickly. Fall is a strong second window — the leaf drop season is a natural cue to schedule gutter cleaning, and a fall soft wash removes the season's algae growth before winter locks it deeper into surfaces.
