Soft washing is the only professional-grade method for removing mold, mildew, and algae from Mercer Island homes without risking damage to siding, trim, or paint. Where pressure washing uses force — often 3,000+ PSI — soft washing uses targeted cleaning solutions at under 500 PSI, killing organisms at the root and preventing regrowth for up to 18 months. It's the approach recommended by siding manufacturers, paint companies, and restoration professionals.
Velocity's Mercer Island soft-wash process starts with a surface assessment to identify materials and contamination severity. We protect your landscaping, apply our biodegradable solution evenly, allow proper dwell time based on growth levels, and rinse for a thorough, lasting clean. Every exterior surface — siding, soffits, gutters, fences, decks, and patios — can be treated in a single visit. Your Mercer Island home comes out looking fresh, and stays that way.

Why Mercer Island Residents Trust Velocity for Soft Washing
Mercer Island's moisture-heavy climate breeds mold, mildew, and algae on siding, fences, and decks. Unlike pressure washing, our soft-wash process kills organisms at the cellular level using low pressure and biodegradable solutions — safe for vinyl, cedar, stucco, and painted wood.
Kills mold & mildew at the root
Mercer Island's moisture-heavy climate breeds mold, mildew, and algae on siding, fences, and decks. Soft washing eliminates growth at the cellular level.

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.”
