Seattle pressure washing & roof cleaning
Seattle's Craftsman and Tudor housing stock plus near-constant damp means moss on the north roof slope is close to universal. We take Seattle jobs, with a focus on north-end neighborhoods and larger or commercial work.
Exterior cleaning in Seattle, WA
In Ballard, Wallingford, Green Lake, Wedgwood, Ravenna and up through Phinney Ridge, the classic 1920s–40s homes have steep roofs that grow moss on every shaded face, mossy brick and concrete walkways, and tight lots with street parking. We handle roof soft washing, house washing, walkway and step de-mossing, and storefront cleaning. Because Seattle is at the edge of our range, we prioritize north-end addresses and jobs of a decent size.
Craftsman, Tudor and box-style homes from the 1920s–40s on tight city lots. About 40 minutes from our Lake Stevens shop.

Local questions, answered
Do you actually come into Seattle?
Yes — mainly the north-end neighborhoods (Ballard, Wallingford, Green Lake, Wedgwood, Ravenna and nearby) and larger residential or commercial jobs. Send your address and the scope and we will tell you plainly whether it pencils out.
My 1930s house has moss on the roof and green all over the front steps. Can you do both?
Yes, in one visit — a low-pressure roof soft wash to kill the moss at the root, and controlled pressure washing to bring the concrete steps and walkway back.
Do you charge extra to come to Seattle?
No travel fee for Seattle — it is inside our core service area (about 40 minutes from our Lake Stevens shop). Free, itemized quotes, most back the same day.
Are you licensed and insured for work in Seattle?
Yes. Olson Landscaping Pro Wash LLC is licensed and carries general liability coverage, with a certificate of insurance available for HOA, commercial and property-management jobs in Seattle.
