Our House Washing Services in Portsmouth
Soft Washing for Coastal Homes
Salt air, humid summers, and shaded yards leave mold, mildew, and green algae streaks on siding across Portsmouth — from older homes near Market Square to newer builds in Atlantic Heights.
Our soft-wash system uses low-pressure detergents to clear those stains without forcing water under siding or stripping paint.
Vinyl, aluminum, fiber-cement, and wood clapboard siding
Brick, cedar shake, and stucco facades
Front doors, trim, soffits, and gutter exteriors
Outdoor furniture, garage doors, and exterior light fixtures
Whether your home is downtown, in New Castle, or near Pease, our crews travel from our Kittery base most weekdays.
Roof, Deck & Driveway Care for Portsmouth Homes
Most house washes pair well with a same-day roof or deck cleaning since the equipment is already on site. We use the right pressure and detergent for each surface:
Asphalt shingle roof soft washing — kills algae streaks without disturbing granules
Wood and composite deck restoration
Paver patios, walkways, and pool decks
Driveways, walkways, and front steps
Built for Portsmouth's Older Homes & Coastal Climate
Portsmouth's housing stock ranges from 18th-century historic homes to mid-century neighborhoods to new construction. We adjust pressure, detergents, and dwell times for each:
Historic homes near downtown: gentle dwell times, careful attention to original trim and woodwork
Coastal homes in New Castle, Rye, and Greenland: salt-residue and oxidation removal
Newer builds in Atlantic Heights: standard soft-wash refresh on a 12–24 month rhythm
Investment properties and short-term rentals: pre-season cleaning and recurring plans

A few Seacoast-specific tips help your home look its best between washes:
Schedule a soft wash every 12–24 months — coastal homes mildew faster than inland.
Wash siding in spring after the salt-air winter, or in early fall before leaves drop.
Don't pressure-wash bare wood or peeling paint — soft washing is the safer call.
Trim back shrubs and trees touching the siding to prevent green algae buildup.
House Washing Tips for Portsmouth Homeowners
FAQs About House Washing in Portsmouth
-
Coastal Portsmouth homes do well with a soft wash every 12–18 months. Salt air, humid summers, and shaded yards mildew siding faster than inland New Hampshire properties.
-
Yes. We use low-pressure detergent application rather than high-pressure water, which protects original paint, wood trim, mortar joints, and historic millwork on older downtown homes.
-
Properly soft-washed siding will not strip sound paint or caulk. We avoid pressure-washing bare wood, peeling paint, or chipping caulk and flag those areas during the quote.
-
Yes. Cedar shake and shingle need extra care so water does not get forced behind individual shakes. We use a gentle soft-wash technique that lifts mildew without disturbing the underlayment.
-
Most single-family homes are a 2–4 hour job for a two-person crew. Larger homes, multi-unit properties, or homes with heavy algae buildup may take a full day.
-
Yes. Our Seacoast routes include Kittery, Rye, New Castle, Greenland, North Hampton, and the rest of the Portsmouth area. We are based just across the bridge in Kittery.
-
Spring after the last salt-air winter, or early fall before leaf drop. We avoid washing during freeze-thaw weeks since standing water under siding can cause issues in cold weather.
-
Most house washes pair well with same-day cleaning of roofs, decks, driveways, walkways, patios, and outdoor furniture since our equipment is already on site.
