A Sunset Rim exterior collects three different things, and only one of them is dirt. It sits in Boise between Maple Grove and Milwaukee, just south of Victory in 83709, and it is a staged build-out recorded 1977–2003 across 14 phases, which puts the oldest homes here well ahead of the newest. It runs about 126 acres, with real variety in elevation and glass package, and that scale is part of the quote.

Exteriors here collect three separate things. On north and east elevations, where sun never fully dries the wall, you get algae and mildew as a green-black film. Along the bottom three feet you get mud splash and irrigation overspray staining — the same mineral that marks the glass marks the siding, and on light vinyl it reads as a permanent dingy band. Everywhere else you get decomposed granite off the foothills, plus the winter inversion that traps particulate at ground level for weeks at a time. Each needs different treatment, which is why one pass with a pressure wand does a poor job on all three. Across about 126 acres the pattern barely varies here.
House washing is a chemical process, not a force one. We apply a surfactant and sodium-hypochlorite blend at low pressure, give it dwell time to kill the growth at the root, and rinse. High pressure drives water up behind lap joints and into the wall assembly, strips the chalking layer off aging vinyl, and on stucco and manufactured stone it will take the finish off outright. Soft washing kills the algae rather than knocking the top off it, which is why it stays gone longer. We pre-wet and rinse every bed on the wash path. On Sunset Rim homes of this vintage we check condition before method, every time.
Two things drive this in Boise: untreated irrigation water off the canal system, and decomposed granite off the foothills, plus the winter inversion that traps particulate at ground level for weeks at a time. Separately each is manageable. Together they bond, and that is the condition we are actually treating on a Sunset Rim job. Sunset Rim routes off Victory, so getting here is not a special trip.
Bundling with window cleaning saves a trip charge and gets the sequence right. We will tell you honestly if you do not need the second service yet — a bundle you do not need is not a saving.
Soft washing removes organic growth and dirt. It will not fix oxidised vinyl, it will not pull efflorescence out of masonry, and it does not repaint anything. We are locally owned and fully insured, and we would rather point you to the right trade than take work we cannot finish well.

Not at soft-wash pressure. The mix is diluted, beds are pre-wet and rinsed, and we never drive water behind lap joints. We will point out anything already failing before we wash it.

$0.18/sq ft soft-wash. The final number depends on the property, and there is no contract and no membership requirement. Booking it alongside another service on the same visit is the cheapest way to do it.
Every one to two years for most homes. North-facing walls and anything shaded by a fence or neighbouring house grow back faster and may want annual attention.
The wash rinses them but it is not a window cleaning — soft-wash mix leaves residue on glass. Book them together and we do the glass after the walls, in that order.
