Siding in Garverdale carries algae on the shaded walls and an irrigation band along the bottom three feet. It sits in Boise south of Ustick, between Five Mile and Maple Grove in 83704, and it is one of the city's original subdivisions, recorded 1910–1911 on one plat. At roughly 142 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. We see it most consistently on the homes along W Landmark St.
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. Being this close to Ustick means the road-facing elevation is always the one that needs the most attention.
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 Garverdale properties go from clean to visibly dirty faster than owners expect. Garverdale routes off Ustick, so getting here is not a special trip.
Garverdale is on our regular Boise route, not a special trip. We already work W Landmark St, W Halstead Dr, N Patricia Ave and N Iris Pl inside the subdivision. It routes off Ustick, which is how we keep travel out of the price. If you can tell us the nearest cross street we can usually quote without a site visit. Where a property is unusual — a lot of divided lites, difficult access, a steep lot — we would rather come and look than guess.
Most Garverdale customers book this alongside window cleaning. Partly that is price, partly sequence — washing walls after cleaning glass puts dirty water back on clean panes, and hanging lights before clearing gutters means working around your own strands in January.

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.
