Soft Washing & Roof Cleaning in Whatcom County, WA
Bellingham's old blocks, Lynden's spotless streets, and Blaine's salt shore: soft washing, roof cleaning, and gutters across Whatcom.
Cleaning Whatcom Homes from the Bay to the Border
Whatcom County stretches from Bellingham Bay to the Canadian border, and each of its towns brings different washing work: Bellingham's craftsman neighborhoods under big trees, Lynden's famously well-kept homes and dairy farms, and the salt-exposed shoreline of Blaine, Birch Bay, and Semiahmoo.
The common enemy is the north-coast climate: long damp seasons that green up siding, mossy roofs under mature trees, and salt film wherever the sea reaches. Soft washing for the old and delicate, roof cleaning and moss and algae treatment county-wide, gutter cleaning that keeps pace with the trees, window cleaning for coastal glass, and pressure washing for concrete when hard surfaces need it.
Wherever you are in the county, quotes are free, written, and honest about what actually needs cleaning.

"They soft washed our roof and siding last summer and the difference was night and day. No moss, no streaks, and the team was careful with the rhododendrons. Booking them again for the fall gutter cleaning."
"Pressure washed our driveway and back patio. Came out perfect. Honest quote up front, on time, cleaned up after. Way better than the rental wand job I tried last year."
"Finally got the upstairs windows done right. They brought a water-fed pole so no ladders against the siding. Screens cleaned and tracks vacuumed too. Will definitely call them again."
"Excellent service from start to finish. They responded quickly to my quote request, arrived right on schedule, and did a meticulous job power washing our back deck. Will definitely use them again!"
"Highly recommend NorthWest Exterior Cleaning! They washed our siding and driveway, and it seriously looks like a brand new house. Fast, friendly, and very reasonably priced."
