Where we work

Olson Pro Wash is based in Lake Stevens — this is home. We know which streets sit under the heaviest tree cover and which lakefront roofs turn green first.

From the historic homes of Rucker Hill to the newer builds around Silver Lake, Everett's marine air and older siding keep us busy year-round.

Marysville runs from the older neighborhoods off State Avenue up to the fast-growing subdivisions in Smokey Point and Getchell — and all of it grows moss.

Arlington's mix of Old Town homes and rural acreage means big rooflines, long gutter runs and a lot of trees dropping debris.

Granite Falls is the gateway to the Mountain Loop — deep forest, a long wet season and serious moss pressure on every roof in town. We're just up the road.

Historic downtown Snohomish is full of century-old homes that can't take high pressure — and the surrounding valley is damp, shaded and moss-prone. We're just up the road.

Sitting in the Skykomish valley at the foot of the Cascades, Monroe gets the humidity, the fog and the tree debris — north-facing walls and roofs go green fast here.

Mill Creek is master-planned and appearance-conscious — most neighborhoods have covenants that require a maintained exterior, and homeowners here expect the work to look it.

Bluff-top and waterfront exposure means Mukilteo homes get salt haze, wind-driven grime and algae — and the views mean owners want them spotless.

Lynnwood's dense mix of 1960s–80s ramblers and split-levels means a lot of aging composition roofs — and almost all of them are carrying moss.

Bothell straddles two counties, with mature landscaping planted right up against the foundation on most streets — so landscape protection matters more here than almost anywhere.

Kirkland runs from Lake Washington waterfront estates to walkable retail cores in Juanita and Totem Lake — premium residential soft washing and tidy commercial frontage are the ask here.

The Sammamish Plateau is prime moss country — large newer homes under dense Douglas fir, with steep roofs and long driveways that green up in the shade.

Tucked against the Issaquah Alps, Issaquah homes have steep roofs and shaded, damp hardscapes that stay green most of the year.

Bellevue homes are held to a high standard — HOA covenants, view-lot expectations and premium finishes mean the exterior has to be spotless and the work has to be careful.

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.

Woodinville pairs large wooded estates on Hollywood Hill and English Hill with a busy warehouse-district wine and event scene — we do both.

From Education Hill and Grass Lawn to the larger homes out toward Union Hill and Novelty Hill, Redmond's mix of tree cover and tech-corridor turnover keeps exteriors in constant need of a refresh.
