Driveway Pressure Washing in Sammamish
Big lots near Beaver Lake and in Inglewood often come with long driveways running out to the road under the trees. On the plateau, those driveways see frosty mornings all winter, and the shaded stretches grow moss that turns treacherous when it freezes.
Frozen moss turns the shady stretch of your driveway to ice
Moss and algae hold water on the surface, and on a cold plateau morning that water freezes into a slick film. On a long driveway, the shaded stretch under the trees is where tires lose grip and feet slip.
Full-slab surface cleaning, edge to edge
Starting at $200 We treat oil and rust spots, clean the whole slab edge to edge, detail every joint and edge, then rinse and inspect the slab. Add polymeric sanding for paver joints if you want it.
Better footing on frosty plateau mornings
With the growth stripped off, less water sits on the concrete overnight, so the shaded section of the driveway is far less slick on the mornings it freezes.
A cracked, re-poured driveway costs far more than routine washing
Left unwashed year after year, trapped water keeps working deeper into the concrete until small cracks become real damage — patchwork repair or a full re-pour costs far more than staying ahead of it with routine washing.

What's included
- Pre-treat. Oil and rust spots get a targeted stain treatment before the main wash, so it has time to break the stain down.
- Surface clean. The whole slab is cleaned edge to edge, matched to your surface, for an even finish with no streaking.
- Edge & detail work. Expansion joints, edges, and tight spots along the garage and walkway get cleaned too, not just the open slab.
- Rinse & inspect. We walk the driveway before we leave. Polymeric sanding for paver joints is available as an add-on.
Worth knowing
Pressure washing can expose problems that were already there — hairline cracks, worn sealant, or loose paver joint sand often show up more clearly once the surface is clean. We'll point out anything we notice, but we can't be responsible for damage from pre-existing wear.
Frequently Asked Questions
Part of our long driveway is gravel. Can you clean it?
We clean concrete and paved surfaces. Pressure washing doesn't help gravel, so we'd quote just the paved part.
Is fall a good time for a driveway wash here?
Early fall is a good choice on the plateau, since it clears the growth before the frosty months. Text us and we'll pick a dry stretch.
How often should I pressure wash my driveway in the Seattle area?
With how much rain and shade the Eastside gets, moss and algae come back fast. Most homeowners get the best results washing once a year, or twice if your driveway sits under trees or doesn't get much direct sun.
Is pressure washing safe for stamped concrete or pavers?
Yes — the clean is matched to the surface. Stamped concrete and pavers get a gentler clean that protects the finish and joint sand, while plain concrete can handle a more aggressive one.
