Siding in South Park carries algae on the shaded walls and an irrigation band along the bottom three feet. It sits in Caldwell on the streets off Moreno Dr in 83607, and it is platted 2001–2006 across 8 phases — mature landscaping, original windows on most homes. At roughly 103 acres and about 438 lots it is one of the larger communities in the city, 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 Canyon County farm dust off the dairy, seed-crop and row-crop ground that still surrounds the city on three sides, plus the harvest traffic that comes with it. Each needs different treatment, which is why one pass with a pressure wand does a poor job on all three. Across roughly 438 lots it is remarkably consistent — South Park is one job, not a hundred different ones.
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 South Park homes of this vintage we check condition before method, every time.
Caldwell is one of the few cities in the valley that runs its own irrigation district — the Caldwell Municipal Irrigation District delivers untreated surface water to yards across town, and a lot of the older grid is still on gravity rather than pressure. What reaches the glass is canal water either way. That is the honest reason we push timing as hard as we push method: doing this work at the right point in the Caldwell season is worth more than doing it more often at the wrong one. If you are on Yucaipa St or one of the streets off it, we are likely already working nearby.
Most South Park 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.
South Park is on our regular Caldwell route, not a special trip. We already work Moreno Dr, Antigua Ave, Yucaipa St and Kerby Ct inside the subdivision. We schedule by area rather than first-come, which keeps drive time down and holds prices where they are.

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.
