Yes — we serve Portsmouth and the surrounding Seacoast area. Historic downtown, Strawbery Banke, South End, North End, Little Harbour — wherever your property is, we come to you. We work with homeowners, short-term rental owners, and commercial property managers across the city.

Salt air off the Piscataqua River and the Atlantic coast is the main culprit. It carries moisture and salt particles that land on siding, roofs, and decks and accelerate biological growth — algae, mildew, and black streaks establish faster here than in inland towns. Properties near Prescott Park and the waterfront feel it most, but it affects the whole city. It's not something you can prevent — just something you need to clean regularly.

It depends on the property size, surfaces, and how much buildup we're dealing with. Portsmouth's older colonial and Victorian homes sometimes need a more careful soft-wash approach than a newer vinyl-sided property. Either way, you get a straight number upfront — no ranges, no surprises on the invoice after the job is done.

High pressure isn't — and we don't use it on older Portsmouth homes. Wood clapboard, brick, and painted trim on century-old properties can't take high pressure without damage. We soft-wash those surfaces using low pressure and biodegradable solutions that clean thoroughly without stressing the material underneath. It's actually the more effective method on older homes — the solution does the work, not the force.

Spring is the busiest window — once temps hold above 50°F. That's when you're clearing a winter's worth of road salt and the mold that built up on shaded surfaces through fall. For short-term rental owners around downtown and the waterfront, spring cleaning before the tourist season is standard. Late fall works well too — cleaning before winter means buildup isn't sitting on surfaces for months. Portsmouth books fast both windows, so don't leave it too late.

We do — and it's one of the most common calls we get in Portsmouth. The short-term rental market here is competitive. Guests look at listing photos closely, and an exterior that looks dirty or uncared for costs you bookings before anyone reads your reviews. We work around your booking calendar and get the job done efficiently. A clean exterior shows up in your listing photos and keeps your ratings where they need to be.

Yes. We use biodegradable, phosphate-free solutions that break down before reaching any waterway. For properties near the Piscataqua River, Little Harbour, or the tidal inlet areas, we follow NH environmental guidelines and plan the job so runoff stays contained. If your property sits right on the water, tell us upfront — we'll walk you through exactly how we handle it.

Once a year covers most Portsmouth properties — the coastal environment is active enough that annual cleaning keeps biological growth from establishing and salt residue from working into surfaces. Waterfront and near-harbour properties sometimes benefit from twice a year. Commercial properties on Islington Street or around Market Square with high foot traffic tend to need it more often just from the visual standpoint. We'll tell you honestly what your property actually needs — we're not trying to oversell visits.

You don't need to be home. As long as we can access the property, we'll handle everything and send before-and-after photos when we're done. A lot of Portsmouth homeowners and rental owners are at work or managing other properties when we come through — that's fine. We document the job thoroughly so you can see exactly what was done.
