Mukilteo drops toward the ferry and the Sound. Salt reaches the lower streets, and the hills above the terminal shed water down through yards that were cut into the slope. A flat inland detail does not survive on these lots. Marine air puts a film on glass, rails, and walks that a garden hose will not move. It also comes back. Washing is maintenance on an exposed lot.

Salt film and mildew
We wash the walks, the patio, the railings, and the siding that can take it. Salt on windows is a rinse, not a high-pressure event. Painted surfaces get tested in a spot. If the paint is failing, pressure will finish it, and we stop.
Runoff toward a bluff or a storm drain is kept reasonable. We are not stripping a cleaner into the Sound for the sake of a brighter patio.
The ground in Mukilteo
Hillside runoff is the job. A patio with a view is also a patio that can send water at the house if the base and the pitch are wrong. We build the drain before the pavers, and we hold the bank with a wall that has rock or drain tile behind it, not a decorative stack sitting on the sod.
Salt-tolerant natives belong on the exposed edges. Pressure washing is how you get the marine film off a walk and a railing; it comes back, so we treat it as upkeep. Lawns on the upper, slightly flatter streets behave more like the rest of the county — clay, moss, shade from big trees — and we maintain them that way. The waterfront lots are a different trade: erosion, wind, and a view you do not want to block with a hedge.
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
Wood versus concrete
Concrete can take a stronger wash. Cedar decks, fences, and soft siding cannot. If we raise the grain, the surface holds more dirt afterward. We would rather leave it a shade less bright than furred.
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.
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.
