Why Rochester homeowners choose Giani Exterior Services
Rochester is the largest community we serve regularly — around 33,500 people spread across 45 square miles, which makes it less one town than six distinct ones. A Victorian near the downtown common has almost nothing in common with a vinyl-sided colonial off Rochester Hill Road, and they need different approaches. We work in all of them: downtown, Gonic, East Rochester, North Rochester, the West Side and Rochester Hill.
We're a small, owner-operated business based in Nottingham, NH — not a franchise. When you call Giani Exterior Services, you're talking directly to the person who will show up and do the work. Every estimate is free, every price is transparent, and every job comes with our 100% satisfaction guarantee.

What pressure washing costs in Rochester, NH
A standard house wash runs $300–$550. Roof washing starts at $400 and varies by roof size, pitch and how far the growth has spread. Gutter cleaning for most Rochester properties runs $175–$325.
Rochester's housing stock is unusually varied, so the quote depends heavily on which part of the city you're in. Compact mill-era homes in Gonic and East Rochester often sit at the lower end. Larger newer construction off Route 11 and around Rochester Hill sits higher. Multi-family properties — common here in a way they aren't in the smaller Seacoast towns — are priced on the actual surface area being cleaned rather than by unit. We give you a written number before any work starts.
Rochester's exterior cleaning challenges
Rochester grew up around the Cocheco and Salmon Falls Rivers, and the mills those rivers powered built most of the older housing here. Two things follow from that. First, river valleys hold humidity, and humidity is what mold, mildew and algae need to take hold — north-facing walls in the older neighborhoods go green faster than almost anywhere else we work. Second, much of the 19th-century housing is wood clapboard with aging asphalt roofs, and that combination does not tolerate high pressure. Forcing water behind old clapboard causes rot you won't see for two years.
We soft wash those surfaces at low pressure with a biodegradable solution that kills growth at the root, and save high-pressure surface cleaning for concrete, walkways and driveways where it belongs. The newer subdivisions have a different problem entirely: south-facing vinyl in Rochester tends to chalk and fade from UV exposure, which is an oxidation removal job, not a washing job.
When to schedule in Rochester
Spring is the busiest season — late April through June — and it books up first. Early April is the right time to call if you want a spring slot. Fall is the quieter and often better option in Rochester: the mature maples through the older neighborhoods drop heavily, and a gutter cleaning in late October or November, once the leaves are actually down, protects your foundation and siding through the winter.
