Professional house washing in Seattle and the Eastside — gently lifting green algae, black streaks, mildew, and grime off your siding without the high pressure that damages surfaces. Our soft-wash process cleans vinyl, stucco, brick, and fiber-cement the safe way.
Send your address and we'll check availability and send a quote — usually within 1–2 hours during business hours. Same-day and next-day slots open up often.
Seattle's damp, shaded climate is perfect for algae, mildew, and moss to take hold on the outside of your home. That green film and those black vertical streaks aren't just dirt — they're living growth that spreads, holds moisture against your siding, and makes even a well-kept house look tired. A garden hose won't touch it, and blasting it with high pressure can crack siding, force water behind panels, and strip paint.
If you're searching for house washing near me, soft washing, or exterior house cleaning in Seattle, cleanNow uses a low-pressure soft-wash process with the right cleaning solution to kill the growth at the root and rinse it away gently. The result is bright, even siding — and a clean that lasts far longer than a quick rinse, because the algae is actually treated, not just knocked loose.
Soft-wash the full exterior to lift green algae, black streaks, and mildew from your siding.
Clean the shaded areas where growth and grime build up most — soffits, fascia, and gutter faces.
Freshen the first thing guests see — the front entry, porch, steps, and railings around your door.
Your siding should be cleaned, not blasted. Here's the difference.
We apply a professional cleaning solution that kills algae and mildew, then rinse at low pressure. The chemistry does the work — not brute force — so nothing gets forced behind your siding.
Because the growth is treated at the root instead of just knocked off the surface, soft-washed siding stays clean far longer than a high-pressure rinse — often a year or more.
A careful process that protects your home while getting the exterior genuinely clean.
We check your siding type, note delicate areas, and protect plants, lights, and outlets before we start.
A professional cleaning solution is applied low and even, killing algae, mildew, and mold at the root.
We rinse the exterior at low pressure from top to bottom, lifting the growth away without harming the surface.
