Soft Washing & Roof Cleaning in Concrete, WA
The deeper you go up the valley, the harder moss works. Soft washing, roof cleaning, and gutters across the upper Skagit.
Roof and Siding Care Under Upper-Valley Tree Cover
Concrete is the upper valley's landmark town - the old cement silos still standing over Highway 20, with Baker Lake and the North Cascades beyond. Homes run from early-1900s company-town houses to river cabins and getaway properties tucked into serious tree cover.
Up here the forest sets the cleaning schedule. Heavy shade and mountain rain mean roofs carry more moss than anywhere downriver, siding greens fast, and gutters fill with needles multiple times a year. Soft washing handles houses and cabins. Roof cleaning and moss and algae removal keep growth from prying at shingles. Gutter cleaning under heavy conifer cover is a regular rhythm, not a one-time fix. Pressure washing helps on decks and walkways that spend most of the year wet.
Concrete is about thirty minutes east of our Sedro-Woolley base on Highway 20, well inside the territory we cover.

"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."
"Had our gutters and roof cleaned before the rainy season started. The crew did an incredible job, cleared away all the debris, and left the property spotless. Very professional team!"
