If your Mercer Island windows look hazy, spotted, or streaked despite regular cleaning, the culprit is likely mineral deposits from PNW hard water combined with organic residue from pollen, algae, and tree sap. DIY methods push grime around without removing the mineral layer underneath. Our professional window washing uses a proprietary formula that dissolves these deposits at the molecular level — restoring true clarity.
Velocity's Mercer Island service goes beyond glass: we clean frames, sills, and tracks, remove and hand-wash screens, and apply a protective wax barrier that actively repels dust and rain spots for months. Both sides of every window are cleaned using drip-free techniques that keep your home's interior protected. The difference is visible immediately — and lasts.

What Makes Velocity the Right Window Washing Team in Mercer Island
Our exclusive wash & wax formula is engineered for Pacific Northwest conditions. While other services leave glass exposed to immediate re-soiling, our protective film repels dust, pollen, and mineral deposits — keeping your Mercer Island windows cleaner for months, not weeks.
Hard water & mineral deposits
PNW rain mixed with Mercer Island's mineral-rich groundwater leaves spots and film on glass. Our wash & wax formula dissolves deposits and prevents new buildup.
Protective wax coating
Our proprietary formula leaves an invisible barrier that repels dust, pollen, and rain spots — keeping windows cleaner up to twice as long.
Interior & exterior
We clean both sides of every window, including tracks and screens. Our drip-free methods protect Mercer Island homeowners' floors and furnishings.
Natural light & energy savings
Clean windows let in up to 30% more natural light, reducing reliance on artificial lighting and improving your home's energy profile.
Our Window Washing Process in Mercer Island
We start with a detailed window count and inspection at your Mercer Island property, noting specialty glass and access challenges. Screens are removed and hand-washed, then our proprietary wash & wax formula is applied to every pane. Each window is squeegeed to a streak-free finish before screens are reinstalled and results reviewed with you.

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.”
