If your Sammamish home's siding looks green, streaked, or dingy despite regular maintenance, the problem isn't dirt — it's biological growth. Mold, mildew, and algae embed into surface pores where rain can't reach them and garden hoses can't dislodge them. High-pressure washing strips paint, splinters wood, and forces water behind siding. Soft washing is the professional solution: targeted chemistry at low pressure that kills growth completely and safely.
Our Sammamish soft-wash crews assess every surface before starting — siding type, contamination level, and areas needing extra protection. We pre-wet landscaping, mask fixtures where needed, and apply our biodegradable solution at low pressure. After the appropriate dwell time, surfaces are rinsed to a fresh, clean finish. The entire process is gentle enough for cedar and painted trim but effective enough to eliminate black mold and years of green buildup.

Why Sammamish Homeowners Choose Velocity for Soft Washing
Delicate surfaces like cedar siding, painted trim, and composite decking can be damaged by high-pressure washing. Our Sammamish soft-wash service uses the right chemistry — not brute force — to clean thoroughly while protecting your home's materials.
Kills mold & mildew at the root
Sammamish's moisture-heavy climate breeds mold, mildew, and algae on siding, fences, and decks. Soft washing eliminates growth at the cellular level.
Safe for all surfaces
Vinyl, cedar, stucco, painted wood, and composite — soft washing uses low pressure and cleaning solutions that won't damage delicate materials.
2–3× longer-lasting results
Because soft washing kills organisms rather than just rinsing them off, your home stays cleaner for 12–18 months versus 4–6 with pressure alone.
Eco-friendly formulas
Our solutions break down into harmless compounds within 30 minutes. Safe for your family, pets, and Sammamish's waterways.

What Our Customers Say
Real Results. Real Homeowners.
“Our driveway looked brand new — we couldn't believe the difference. The crew was professional, on time, and cleaned up after themselves. Neighbors have already asked for the number.”
“Had moss covering half our roof. Velocity removed everything without any damage to the shingles. Six months later it's still clean. Worth every penny compared to what a new roof would cost.”
“We hired them before listing our home. The soft wash made the siding look 10 years newer. Our realtor said it was the best pre-listing investment we made. Sold in four days.”
