Pressure Washing in Sammamish, WA

Between Sammamish's rain, shade from mature trees, and Pacific Northwest humidity, hard surfaces accumulate moss, algae, oil stains, and ground-in dirt faster than anywhere else in the country. DIY pressure washers often make things worse — too much pressure etches concrete, strips paint, and splinters wood. Velocity's trained technicians know exactly which pressure, angle, and solution each surface needs for a thorough, damage-free clean.

Our Sammamish process begins with eco-friendly pre-treatments that kill organic growth at the root — not just the surface. We then work through driveways, walkways, patios, siding, fences, and decks with equipment dialed to the right PSI for each material. Sensitive plantings and fixtures are protected before we start, and all debris is cleaned up before the final walkthrough.
