Soft Washing & Roof Cleaning in Hamilton, WA
Low, damp, and close to the river, Hamilton grows moss like a crop. Soft washing, roof cleaning, and gutters keep pace.
Controlling Growth in the Damp Upper Skagit
Hamilton sits low along the Skagit River on Highway 20, a small upriver town where the air stays damp and the shade runs deep. For an exterior cleaner, that combination means one thing: growth. Moss on roofs, algae on siding, slick green film on every walkway.
Upriver homes benefit from a regular cleaning rhythm more than almost anywhere we work. Soft washing clears algae-heavy siding. Roof cleaning and moss and algae treatment protect shingles before growth lifts them. Gutter cleaning keeps systems flowing ahead of the heavy rains. Pressure washing de-slicks the walks and steps that get genuinely dangerous by midwinter.
We're about fifteen minutes up the highway, so Hamilton is close-to-home territory, and we're honest about what needs cleaning now versus what can wait a season.

"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."
