Sultan sits on the Sultan River, on the way up the highway toward the trails and the passes. Yards step with the terrain. Water comes off the higher ground, crosses a lawn, and heads for the river or the ditch. Foothill buildings stay damp. The walk from the drive to the door is often slick. That is a safety wash, and it is also a place we do not want to strip the surface off.

Concrete, siding, and the mossy walk
We clean the slick film and the siding that has gone green on the timber side. Water is directed away from the crawlspace. On a slope, the runoff has to go somewhere that is not under the house.
Stone walls get a light clean if you want the face readable. We do not try to make fifty-year-old rock look new. That means blasting the face off.
The ground in Sultan
The useful projects are the ones that make a sloped lot walkable: a gravel path that stays put, a rock wall where the bank is cutting, a drain at the top of the slope so the patio is not the creek. Forest edge is close. Alders and maples lean in, and after a wind the cleanup is limbs, not a few leaves on a patio.
Lawns exist on the benches. They need seed that can take shade at the tree line and a soil that is often thin. We do not promise a golf-course surface against the timber. Native mountain plants hold the cuts better than a bark bed that just slides downhill in January. Access for machines is usually fine along the highway side and tight once you are in the trees. We look at that before we promise a wall.
How we do the work
Most of what people call pressure washing here is organic film: the black and green on the north side, the walks, the fence. The fix is the right tip, the right distance, and often a wash that kills the growth so it does not return in a month. A zero-degree tip on a soft wood deck is how you get a furred, ruined deck.
We do not drive water up under lap siding or into a vent to prove the washer is strong. High pressure is for concrete that can take it. Wood, paint, and mortar joints get a softer approach.
What we look at first
- What the surface is
- Where the water will run
- Plants and outlets we need to protect
- Whether the black is mildew that needs a treatment, not just a blast
How often
North sides and shaded patios, about once a year if you care. Sunny south walks can go longer. Exposed marine rails may want it yearly. We do not sign you up for a monthly wash of a surface that does not need it.
Treatment
A wash that kills the algae and mildew, applied and rinsed, is why the surface stays clean longer than a blast. We use it where the film is biological. We do not soak your vegetable bed in it. Plants get rinsed.
What will not come out
Rust, deep oil, and etching that is already in the concrete. We can fade some of it. We will not promise a new slab. Paint that is loose will leave with the dirt, and you will see the bare spots. We point those out first if we can.
