When homeowners search for house washing near me, house soft washing in Seattle or siding cleaning in Bellevue, they are usually staring at the same problem: a green film creeping across the shady side of the house, black mildew streaks under the eaves, cobwebs in every corner and a home that looks years older than it is. Deep Water Pressure Washing brings that home back to life with a professional soft wash built for Pacific Northwest siding.
Unlike blasting a house with high pressure, soft washing pairs a gentle, low-pressure rinse with professional cleaning solutions that soak into the growth and kill algae, mold, mildew and lichen at the root. The result is a deeper, longer-lasting clean that protects your siding, trim, windows and paint instead of forcing water behind the boards or chipping the finish.
From the craftsman bungalows of Ballard and Fremont to the hillside homes of Queen Anne the classic houses and townhomes of Capitol Hill, and the lakeside homes of Madison Park and Washington Park, Seattle homes sit under big street trees and steady marine air. North walls rarely dry, so algae and mildew take hold fast. Our soft wash clears it from cedar, vinyl and fiber cement without harming older paint or delicate trim.
In Somerset, Bridle Trails, Lakemont and West Bellevue, homes are a major investment with large walls, tall gables and detailed trim. We wash every level safely from the ground and from ladders where needed, leaving siding, eaves and gutter faces bright without the risk of high-pressure damage.
Lakefront estates in Medina, Hunts Point and Yarrow Point, hilltop homes in Clyde Hill and West Bellevue, and the wooded properties of Mercer Island and Sammamish collect lake mist, pollen and green algae on every shaded wall. We soft wash cedar, stucco, stone and painted siding gently and protect the landscaping these homes are known for.
Education Hill, Overlake, Grass Lawn and Redmond Ridge homes live among tall evergreens that shade walls and drop needles all year. Newer townhome communities near Downtown Redmond pick up the same green film within a few seasons. A regular soft wash keeps new homes looking new and gives older homes their curb appeal back.
Across all three cities, the long damp season, heavy tree cover and pollen keep siding wet and feeding organic growth. Our house washing process is built for exactly these conditions, so your home stays cleaner for longer between visits.

Choosing who cleans your home is about more than finding someone with a pressure washer. It takes a crew that knows how each siding material reacts to water and cleaning solutions, understands what the Northwest climate does to a house, and can remove years of buildup without leaving damage behind.
That is the reputation Deep Water has built with homeowners in Seattle, Bellevue and Redmond: careful work, honest communication and results you notice from the street.
Every home gets the same care and attention to detail, whether it is a Fremont bungalow or a three-story Bellevue home.

Every home is built differently, and no two exteriors should be cleaned the same way. Too much pressure on siding, trim or painted wood leads to costly damage, which is why our house washing is centered on a low-pressure soft wash that lifts contaminants while protecting the finish.
Each season in the Puget Sound leaves something behind: spring pollen, fall leaves and needles, and winter rain that feeds algae, mildew and moss. Our process reaches beyond the surface dirt to remove the organic growth that causes stains to keep coming back.
We safely clean nearly every exterior surface, including:
Every wash is tailored to your home’s materials, sun exposure, landscaping and level of buildup, so you get the safest and most effective clean possible.
A professional house wash does far more than make your home look clean. It is preventive maintenance. In Seattle, Bellevue and Redmond, algae, mold, mildew, pollen and road grime are constantly working on your siding, trim and paint. Left alone, they cause staining, hold moisture against the house and wear finishes out early. A regular soft wash removes them before they can do real damage.
The benefits of regular house washing include:
With routine house washing, your home stays cleaner, brighter and better protected through every season in the Puget Sound.

Honest answers about keeping your home clean in the Pacific Northwest climate.
Every home is different, so the price depends on the size and height of the house, the type of siding, how much algae and mildew has built up, and how easy each side is to reach. Deep Water keeps pricing affordable and upfront with no hidden fees, and every job starts with a free, no-obligation estimate so you know exactly what you are paying before we begin.
That green film is algae, and it thrives in the Seattle area because marine air, steady rain and shade from tall trees keep siding damp for much of the year, especially on north-facing walls. Our low-pressure soft wash kills the algae at the root instead of just rinsing it off, so it takes much longer to come back.
Yes. Soft washing uses low pressure and cleaning solutions matched to each surface, so it is safe for vinyl, fiber cement, cedar, painted wood, stucco and brick. We protect outlets, light fixtures and doors, and rinse windows as we go, which avoids the stripped paint, forced-in water and broken seals that high pressure can cause.
Most homes in Seattle, Bellevue and Redmond look their best with a house wash once a year. Homes under heavy tree cover, near the water or with walls that never see sun may need it more often. We can set up a simple yearly plan so your home stays clean without you having to keep track.
No. We pre-wet and rinse your plants and lawn, use eco-friendly solutions, and control runoff during the wash. Pets and kids can head back outside once everything has been rinsed and has had a short time to dry.
Yes. Cedar and other wood siding is cleaned with a gentle soft wash and wood-safe solutions that remove algae, mildew and gray weathering without raising the grain or splintering boards. Many Ballard, Fremont and Queen Anne homes have original cedar, and we treat it with the care it needs.
Yes. Every house wash includes soffits, fascia and the outside of the gutters, where we remove cobwebs, wasp nests and the black “tiger stripes” that run down gutter faces. Interior gutter cleaning can be added to the same visit.
No. As long as we can reach an outdoor water spigot and all sides of the house, you are free to go about your day. Just close windows and doors, move fragile items off porches and decks, and we will send photos and a quick update when we are done.
