Transform Your Building Into a Landmark People Notice

Owners and property managers searching for commercial building washing in Seattle, office building pressure washing near me or commercial soft washing in Bellevue are usually looking at the same thing: green algae on the north walls, black streaks under the rooflines, dirt and cobwebs around entries and signs, and a facade that looks older than it is.

Our commercial building washing covers office buildings, medical and professional centers, mixed-use and multi-story buildings, churches, schools, storefronts and tilt-up buildings.

Soft Washing for Roofs & Buildings

Safe for every facade

Surfaces We Clean

Complete Care for Every Wall, Window Frame and Roofline

A commercial building is made of many different materials, and each one needs the right method. Painted walls, stucco and EIFS need gentle soft washing. Concrete, brick and block can handle more. Glass, frames, signs and metal panels need careful rinsing so they dry clean.

In the Puget Sound area, rain, shade and nearby evergreens keep north and east walls damp for much of the year. That feeds the green algae, black streaks and mildew that make a building look neglected. Our process removes the growth at the root, not just the surface dirt.

We clean every exterior surface on commercial buildings, including:

Painted Walls, Stucco & EIFSSoft washing that removes algae, mildew and streaks without harming the finish.
Concrete, Brick & BlockDeep cleaning for tilt-up walls, masonry and retaining walls.
Metal Panels & SidingRemoves oxidation film, dirt and grime from metal, vinyl and fiber cement.
Entries, Canopies & AwningsCleans the spaces visitors see first, from the canopy to the door frames.
Rooflines, Parapets & GuttersRemoves black streaks, moss and buildup from upper walls and roof edges.
Window Frames & Storefront GlassRinsed clean so frames and glass match the freshly washed walls.
Signs, Columns & LightingDetail cleaning for the features that carry your brand.

Every job is planned around your building, its materials and its tenants, so you get the safest and most effective clean possible.

Benefits of Commercial Building Washing

Protect Your Investment and Impress Every Visitor

Regular commercial building washing does far more than make a property look good. In Seattle, Bellevue and Redmond, algae, mildew and grime are always working on your facade. They stain paint and stucco, shorten the life of coatings and sealants, and quietly tell visitors the building is not cared for.

The benefits of regular commercial building washing include:

A Professional First ImpressionA clean, bright building tells customers and clients your business pays attention to detail.
Attract and Keep TenantsWell-kept buildings lease faster and give tenants a reason to stay.
Protect Paint, Stucco & SealantsRemoving algae and mildew helps prevent staining, rot and early wear.
Delay Costly RepaintingWashing a facade often brings back its color and pushes repainting further out.
Healthier ExteriorsRemoves mold, mildew and grime from entries, walls and walkways people use every day.
Boost Property ValueClean, well-maintained buildings support stronger rents, sales and owner confidence.

With a simple recurring washing plan, your building stays brighter, better protected and ready to impress all year long.

FAQ

Commercial Building Washing Questions, Answered

Straight answers for building owners and property managers in the Pacific Northwest.

How much does commercial building washing cost in Seattle?

Every building is different, so the price depends on its size and height, the materials on the facade, how much algae and staining has built up, access and lift needs, and whether entries, signs or walkways are included. Deep Water keeps pricing affordable and upfront with no hidden fees, and every building starts with a free, no-obligation estimate and a clear written quote.

Is soft washing or pressure washing better for a commercial building?

Most painted walls, stucco, EIFS and siding should be soft washed with low pressure and professional cleaning solutions, which remove algae and mildew without damaging the finish. Concrete, brick and flatwork can take higher pressure. We choose the right method for every surface on your building.

Can you wash multi-story buildings?

Yes. We use lifts, extension equipment and soft washing systems to safely clean walls, trim and rooflines on multi-story buildings in Seattle, Bellevue and Redmond.

Can you work around our tenants and business hours?

Yes. We plan the work side by side, coordinate access and parking with your manager, and can schedule early mornings, evenings or weekends so business keeps running.

How often should a commercial building be washed?

Most commercial buildings in the Puget Sound area benefit from a full wash every one to two years, with entries and high-traffic areas cleaned more often. Shaded walls under trees may need it sooner. We can set up a recurring plan that fits your budget.

Why do Seattle-area buildings get green algae and black streaks?

Rain, shade and nearby evergreens keep walls damp for long periods. That moisture feeds algae, mildew and airborne grime, which show up as green film and black streaks below rooflines and windows. Soft washing removes the growth at the root so it takes much longer to return.

Are you licensed and insured for commercial buildings?

Yes. Deep Water Pressure Washing is fully licensed and insured (Lic# DEEPWWP767KO), and we are happy to provide proof of insurance to your property manager or owner before work begins.

Every service is backed by honest, upfront pricing, dependable results and a free, no-obligation estimate. Have a question we didn’t cover? Call or text 206-414-8499.
