House Washing in Vancouver, WA
Low-pressure soft washing that kills algae and mildew at the root and lifts years of green and gray grime off your siding — without blasting water behind your walls.
Why Homes in Vancouver Turn Green
If you live in Clark County, you already know the look: a north-facing wall streaked with green and a faint gray film creeping across the siding. That is algae, mildew, and airborne mold spores feeding on the constant moisture our wet season delivers from October through May.
Douglas firs and big-leaf maples drop sap, pollen, and debris onto your roof and siding, which feeds the growth further. The longer it sits, the more it etches into the surface. A good house wash does more than make the home look fresh — it removes the organic film that slowly breaks down paint, stain, and siding material.
Soft Wash, Not Pressure Wash
We do not blast your siding with high pressure. High pressure forces water behind vinyl and lap siding, which leads to hidden moisture and rot. It can also etch painted surfaces and strip the finish off softer materials.
Instead we use soft washing — a low-pressure application of biodegradable detergent that kills algae and mildew at the root. The solution does the work, and we rinse with pressure lower than your garden hose. The result lasts far longer than a high-pressure rinse that just trims the visible growth.
What We Clean on Your Home
Vinyl & fiber cement siding
The most common siding in Clark County. Soft washing restores the original color and removes the green algae and dark streaking without damaging the panels.
Stucco & brick
Low pressure is the only safe method here. We lift mildew and carbon staining out of porous stucco and brick without driving water into the wall cavity.
Exterior gutters & fascia
We wash the exterior face of your gutters and fascia boards as part of the house wash. Heavy tiger-striping can be added with gutter brightening.
Soffits & window exteriors
We rinse soffits and the exterior glass. For a fully streak-free finish inside and out, add window cleaning to your visit.
How Much Does House Washing Cost in Vancouver, WA?
A professional house wash starts at $399. That covers a standard single-family home with typical algae and mildew buildup.
What moves the price up from there:
- Home size: larger square footage means more surface area and solution.
- Stories: a two-story or split-level home requires more setup and ladder work.
- Buildup severity: homes that have not been washed in years take longer to treat and rinse.
- Add-ons: driveway, roof, or gutter cleaning bundled into one visit.
Every quote is fixed and upfront — no surprise charges after the work is done. See full pricing on our pricing page.
