Most East End houses aren't sided in anything modern. Historic district review keeps vinyl off these blocks, so what we're washing is 1905-1935 painted wood lap, cedar shingle, brick and a little original stucco, and the three things that stain it here are sprinkler overspray, shade-side algae off the river canopy, and sun-chalked paint.
Drive these blocks and you're mostly looking at painted wood: horizontal lap siding on the Craftsman bungalows and Foursquares, cedar shingle in the gable ends and dormer cheeks, and clinker or common brick on the Tudors and on porch piers all over the neighborhood. A handful of 1920s bungalows still carry original stucco. What you almost never see here is vinyl, because historic district design review keeps owners from swapping it in. So the surface we're washing has been on the house somewhere between 40 and 120 years, and that changes the job. Vinyl out in Meridian takes a soft wash and shrugs it off. Century-old paint over old-growth fir needs the pressure kept down, the mix kept mild, and someone watching the wall the whole time it's happening.
The most common thing we get called for in East End isn't general dirt, it's the band across the bottom two or three feet. Treasure Valley water is hard, and older yards here run older irrigation: fixed heads set close to the foundation, aimed at planting beds that have grown in over decades, so the spray now hits siding instead of soil. On painted wood that leaves a chalky white mineral line plus a dirt-and-splash band underneath it. On brick it's worse, because the mineral soaks into the face of the brick rather than sitting on top. A soft wash takes the organic film, the splash dirt and the algae growing in that permanently wet zone right off. The mineral scale is a separate problem and we'll say so standing there: it needs a masonry-safe descaler, and it comes back within a season unless the head gets moved or a deflector goes on.
East End's tree cover is the reason the north walls look the way they do. Silver maple, linden and elm shade the north and east elevations most of the day, the Boise River corridor holds humidity a block or two off the Greenbelt, and paint that gets no direct sun from October through April simply stays damp. What grows there is green algae: a flat green-black film on painted lap siding, always heavier in shingle courses where water sits in the shadow line under each butt edge. Most people call it mold. It's usually algae, and pressure alone does not kill it. Blasting knocks the top layer off and it's visibly back by August. The soft-wash mix kills the growth instead of just removing the color, which is the difference between a north wall that stays clean a year and one that greens up in two months.
South and west walls have the opposite problem. A century of full afternoon sun breaks down the binder in old paint and leaves chalk, the white powder that comes off on your hand. Washing removes the chalk, and homeowners are sometimes surprised the wall underneath reads flatter and more faded than the shaded side. That isn't damage from the wash; it's what the chalk was hiding. Two honest limits on houses this old. If paint is already peeling, curling or checking, a wash will carry loose flakes off with it. That wall is a paint job, not a wash, and we'll tell you before we start rather than after. And on pre-1978 paint we keep pressure low and do nothing that abrades or strips a surface. Disturbing old paint belongs to a licensed painter's scope, not ours.
House washing runs $0.18 per square foot, soft-wash, safe on every surface in this neighborhood: painted wood, cedar shingle, brick, stucco. We work top down, pre-wet and then rinse the foundation planting that most East End homes have grown in tight against the wall, cover what shouldn't get wet, and hand-detail around old wood window trim and sills instead of driving water into glazing lines. Best window here is after cottonwood fluff finishes in late June and before the fall leaf drop, so the wall goes into winter clean.

Not the way we do it. Soft washing means low pressure and a mild mix doing the work, not a pressure wand. The risk on these houses isn't the water, it's paint that was already failing. Sound paint washes fine. Paint that's peeling or checking will shed loose flakes no matter how gentle you are, and we'll walk the wall with you first and tell you which one you've got.
Almost always sprinkler overspray. Hard Treasure Valley water dries on the wall and leaves mineral scale, usually on the lowest two or three feet where a fixed head is hitting siding instead of the bed it was aimed at decades ago. The wash takes the dirt, algae and film in that zone off. The mineral itself needs a descaler, and it will return next summer unless the head is moved or capped with a deflector.
Usually algae, not mold. Under East End's maple and elm canopy, north and east walls get almost no winter sun and stay damp for months, which is exactly what algae wants. It matters because pressure alone only removes the color. The growth stays alive in the paint's surface and returns within weeks. A soft-wash mix kills it, which is why a treated north wall holds for about a year instead of two months.
No. On pre-1978 paint we keep pressure low and do nothing that abrades, sands or strips the surface, because that's what makes old paint a hazard. A soft wash rinses dirt and kills algae without taking the coating off. If a wall genuinely needs the paint removed, that's a licensed painter's job and we'll say so instead of trying to do it with water.
Late June through September. Cottonwood fluff off the Boise River runs roughly two to three weeks in late May and June, and washing before it's done just means fluff matted onto a clean wet wall. Finish after that and before the October leaf drop, so the north side goes into winter with the algae killed rather than feeding on damp leaf litter piled against the foundation.
$0.18 per square foot, soft-wash. East End's older footprints are often smaller than newer valley homes, but two-story Foursquares and steep-gabled Craftsmans add wall area fast, so square footage of siding is what we price on, not lot size. Quarterly or Monthly memberships bring the per-visit cost down with no contract. Call (208) 453-6760 and we'll give you a real number for your walls.
