Soft Washing in Skagit, Whatcom, Snohomish, Island & San Juan County
Soft washing safely lifts moss, algae, mildew, and grime off roofs and siding without the surface damage you get from pressure alone.
Soft Washing Specifics
Here's what falls under this service when you give us a call.
- Roof soft washing: moss, algae, lichen removal
- Siding wash: vinyl, painted wood, fiber cement, stucco
- Brick and stone exterior cleaning
- Fence cleaning (cedar, painted, vinyl)
- Composite deck cleaning
- Treatment that kills moss/algae at the root, not just on the surface
- Plant protection: pre-wet, cover, rinse
Pacific Northwest weather is hard on exteriors. Moss takes hold on north-facing roofs, algae streaks down siding, and mildew creeps into shaded corners. Pressure washing those surfaces strips the protective layer and shortens their life. Soft washing uses a low-pressure rinse paired with biodegradable cleaning solutions that kill the organisms at the root, so the surface stays clean for longer instead of regrowing in a season.
We soft-wash composition and cedar roofs, vinyl, painted wood, fiber cement, stucco, brick, and stone. We pre-wet landscaping, cover sensitive plants, and rinse everything thoroughly when we're done. The result is a clean exterior that holds its color, plus a roof that drains the way it's supposed to instead of growing a moss carpet.

"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."

Soft Washing FAQ
Quick answers to the questions we hear most about this service.
In the Pacific Northwest, most roofs benefit from a wash every 2–4 years depending on tree cover, shade, and the slope. Heavy moss buildup means it's already overdue.
We pre-wet plants, cover anything sensitive, and rinse thoroughly during and after the job. The biodegradable mix breaks down quickly and is safe around landscaping when applied carefully, which we do.
High pressure on shingles strips granules and on cedar tears up the wood fibers. Both shorten roof life and can void manufacturer warranties. Soft washing cleans without the damage.
