Edmonds faces the Sound. Salt air reaches the patios, the wind comes off the water, and the soils change as you move up off the beach — sandier near the shore, heavier as the hills rise toward the ferry and the bowl downtown. 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 Edmonds
A yard with a view of the water is also a yard in the wind. Screens and plantings have to stand up to salt and to gusts that shred a soft shrub in one winter. Madrone, shore pine, and kinnikinnick already grow on these bluffs for a reason. We use that palette when a client wants the bank to stay put without a weekly watering schedule.
Lower down, salt film builds on pavers and railings, and a pressure-wash is maintenance, not a one-time event. Retaining work on the west-facing slopes is about holding a sandy bank, with drainage behind the wall so the hill does not load up and shove. The older neighborhoods up the hill have more conventional clay and bigger trees, so we do not treat every Edmonds lot like a beach cottage.
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.
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.
