Soft Washing in Vancouver, WA

Soft washing is not just "pressure washing turned down." It is a completely different method. We apply a biodegradable detergent that kills algae, mildew, and mold at the root, let it dwell, and then rinse with pressure lower than your garden hose.

The chemical does the cleaning, not the blast. That matters in the Pacific Northwest, where the green and gray on your home is living organic growth. If you only blast it off, the spores are still embedded in the surface and it grows right back. Soft washing kills those spores, so the surface stays clean for a year or more instead of a few weeks.

We use both methods — the right one for the right surface. High pressure belongs on hard, porous surfaces like concrete, driveways, and pavers, where it lifts deep stains and heavy grime.

Soft washing belongs on everything that high pressure would damage: vinyl and siding, stucco, painted surfaces, wood, and roofs. High pressure on these surfaces forces water behind siding, etches paint, and strips the granules off shingles. Soft washing gets them clean without any of that.

Our climate is basically a greenhouse for algae and mildew. Eight months of rain, heavy tree cover from Douglas firs and maples, and short winter days mean siding and roofs stay damp and shaded for long stretches. North-facing walls almost never see direct sun, so they go green first.

That growth is not just cosmetic — it feeds on and slowly breaks down paint, stain, and roofing material. A scheduled soft wash removes the organic film and protects the surface underneath. That is why so many Clark County homeowners pair a house wash with roof cleaning in a single visit.

Soft washing is priced by the surface being treated:

• House wash (siding): starts at $399
• Roof soft wash: starts at $549, up to $900+ for large or heavily mossy roofs

The price moves with the size of the area, the number of stories, and how heavy the algae and moss growth is. We give a fixed, upfront quote before any work starts — see all starting prices on our pricing page.
