A Dallas Harris Estates exterior collects three different things, and only one of them is dirt. It sits in Boise south of Overland, east of Broadway in 83716, and it is a staged build-out recorded 2010–2019 across 17 phases, which puts the oldest homes here well ahead of the newest. At roughly 125 acres it is one of the larger communities in the city — which is what the quote is built from.

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. With 17 phases recorded, the older streets show it further along than the newest ones, and we price accordingly.
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. That holds across 83716 generally, not just on this plat.
The local variable here is decomposed granite off the foothills, plus the winter inversion that traps particulate at ground level for weeks at a time. It does not act alone — it lands on glass and siding still damp from irrigation and binds into the mineral film, which is why Dallas Harris Estates properties go from clean to visibly dirty faster than owners expect. If you are on E Wolf Tree St or one of the streets off it, we are likely already working nearby.
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. Saying this plainly costs us the occasional booking and saves everybody the version where you find out on the day.
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.

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.
