Professional soft washing across the Bay Area

From moss-covered roofs in the fog belt of Daly City to algae-stained wood fences baking in South Bay heat, soft washing is the safest way to restore exterior surfaces without causing damage. NorTech connects you with background-checked, vetted local providers who handle low-pressure detergent treatment for roofs, painted siding, stucco, wood decks, fences, and fascia — all at a price you approve before any work starts. No hourly meter, no surprise invoice, just surfaces that look clean and treated to stay that way. Whether your property is on the Peninsula, in the East Bay, or in the South Bay, your provider brings the right biodegradable solutions and equipment to protect your home's exterior finish.

Every exterior surface, one trusted platform

Soft washing covers a wide range of exterior cleaning needs: asphalt shingle and tile roof treatment to eliminate algae and lichen, painted wood and fiber-cement siding cleaned without paint damage, stucco surfaces treated for mildew and biological growth, wood decks and fences restored before sealing or staining, and fascia boards cleared of grime and organic buildup. vetted pros on NorTech work on single-family homes throughout the Bay Area, multi-unit residential properties, high-end homes with delicate painted or wood finishes, rental turnovers where curb appeal matters fast, and property managers and short-term-rental hosts who need reliable exterior upkeep on a schedule.

Low pressure, eco-safe solution: cleaning siding, stucco and roofs

Soft washing swaps force for chemistry: a low-pressure rinse with an eco-safe cleaning solution that lifts algae, mildew and grime from siding, stucco walls and roofs without gouging them. You choose what is being washed (siding, stucco, roof, or house and roof), a size band, the number of stories and, for roofs, the pitch, and moss and algae treatment can be added. The price shown is built from those answers.

When to book soft washing

Black or green streaks are running down your roof shingles — a sign of algae or lichen growth that shortens shingle life if left untreated.
Your painted siding or stucco has a chalky green or gray film after a wet winter, making the whole house look weathered from the street.
A wood fence or deck has turned dark and slippery with mildew, and you want it cleaned before applying a new coat of stain or sealant.
You are listing your home or short-term rental and need the exterior to look its best fast, without risking paint damage from high-pressure washing.
Your HOA or a prospective buyer has flagged moss, algae, or biological staining on the roof or exterior surfaces during a walkthrough.
You noticed the fascia boards or eave trim are covered in grime and organic buildup after another Bay Area rainy season.

Frequently asked

Soft Washing — common questions

What you are washing, the size of the surface, the number of stories and the roof pitch if a roof is involved all feed the price, and moss and algae treatment is an optional extra. The eco-safe solution, the low-pressure wash and the rinse are included in the total you see before booking.

Yes. Every soft washing job booked through NorTech is backed by a 72-hour Satisfaction Guarantee. If treated surfaces were missed or do not meet the standard of the work agreed upon, report it within 72 hours and your provider will make it right at no additional cost. Before-and-after photos are taken on every job so the results are documented.

Pressure washing uses high water force to remove surface dirt, which can crack roof tiles, strip paint, damage wood grain, and push water behind siding. Soft washing uses low pressure combined with a biodegradable detergent solution that kills algae, mold, lichen, and mildew at the root — cleaning more thoroughly while protecting the surface itself.

Low-pressure soft washing is the method most roofing manufacturers recommend for cleaning asphalt shingles, precisely because high-pressure washing can void shingle warranties and cause granule loss. Your provider uses a detergent application that treats the biological growth causing those streaks without damaging the shingle surface.

Most soft washing visits for a standard single-family Bay Area home take two to four hours depending on the number and condition of surfaces being treated. You do not need to be home during the service, though your provider will confirm access requirements — such as gate codes or water spigot location — when they confirm the appointment.

Results vary by surface type, sun exposure, and how much moisture the area receives, but most soft washing treatments keep algae and mildew growth suppressed for one to three years. Bay Area homes in foggier microclimates or with heavy tree canopy overhead may benefit from treatment more frequently than homes in drier, sunnier locations.
