Alpine Pointe's custom homes between McMillan and Chinden mostly run stucco over stacked-stone wainscoting, not the vinyl lap you see on the older tract streets south of here — and that render shows every mineral streak the big-lot sprinklers throw at it.
Most of what we wash out here is a stucco field over a stone or manufactured-stone wainscot at the base, sometimes with Hardie fiber-cement trim at the gables — a step up from the vinyl siding on the tract streets closer to town. Stucco is porous. It absorbs water instead of shedding it, and a wand run at driveway-pressure PSI can drive water behind the coat, force it through hairline cracks around window returns, or blow out the sealant at trim joints. We soft-wash it: low pressure, a cleaner rated for cementitious surfaces, dwell time to break down the film, then a rinse. It's the only method that's actually safe on stucco and stone in the same pass, and it's why the price is per square foot, not per house.
Alpine Pointe's lots and irrigation zones run bigger than the tract grid to the south, so the heads throw farther — past the foundation bed and up the stucco, sometimes as high as the sill line on ground-floor windows. That water is pressurized canal irrigation, untreated and full of mineral silt, and it dries to a tan-gray streak running straight down from wherever the spray pattern hits. It's worse on walls backing up to a rotor-head zone instead of a spray head. A hose won't touch it once it's baked on for a season; soft-wash lifts it. One honest note: a chalky white crust in the stone's mortar joints, rather than a streak on the stucco itself, is usually efflorescence — mineral salts leaching from inside the stone — and it can return after a freeze-thaw cycle even after a proper wash, because the source is inside the material, not on top of it.
Walls that face north or sit shaded by a neighbor's roofline get less afternoon sun to dry them out, and on a lot with foundation planting right against the stone wainscot, that shade plus sprinkler moisture is exactly what algae and mildew need. It shows up as a green-to-black film low on the wall, worst right where the stone meets the stucco, and it spreads upward slowly over a season if it's never washed. It's cosmetic, not structural, but left long enough it does etch into a porous stucco finish and gets harder to lift. This is the elevation we check first on an Alpine Pointe estimate, because it's usually further along than the homeowner realizes — it's just on the side of the house nobody walks past.
The sun-facing elevations here fade differently than they stain. Idaho's UV load breaks down the acrylic binder in stucco coatings over years, and the pigment chalks — you'll see it as a dull, powdery haze that rubs off gray-white on your hand. That's not soil sitting on top of the wall; it's the coating itself wearing out. Soft-washing pulls off the dust, pollen, and grime layered over that chalking and the wall will look noticeably cleaner, but it won't restore the original color or stop the chalking from continuing. If a south or west wall looks faded even right after a wash, that elevation is due for a re-coat or elastomeric paint, not another cleaning — we'll tell you straight if that's what we're looking at.
Soft-wash house washing runs $0.18 a square foot and works on stucco, stone, Hardie, and vinyl alike — one method, no pressure high enough to force water behind any of them. We quote off actual square footage, so a bigger custom plan with more wall runs more than a smaller one, and we'll flag anything that's chalking or efflorescence rather than dirt before we start so you're not paying to wash something a cleaning can't fix. Memberships run Monthly or Quarterly with no contract, and the 7-Day Rain Guarantee covers a re-clean if rain marks the work within a week.

Soft-wash only. Stucco is porous, and a pressure washer run at normal driveway PSI can force water behind the coat at window returns or hairline cracks, and blow out trim sealant. We use low pressure with a cementitious-rated cleaner and dwell time instead, which lifts the film without pushing water where it doesn't belong — the same method we use on the stone wainscot and any Hardie trim.
That's algae or mildew, and it takes hold where shade and moisture overlap — usually a north-facing elevation or a wall shaded by a neighbor's roofline, right where foundation planting keeps the stone damp. It's cosmetic, not structural, but it does spread and etch into porous stucco the longer it sits. It's the first thing we check on an Alpine Pointe estimate because it's usually worse than it looks from the driveway.
Depends what it is. If it's on the stucco field itself and rubs off gray-white on your hand, that's UV chalking — the coating breaking down after years of sun, not dirt. A wash will clean the grime layered on top of it but won't restore the color or stop it from continuing; that needs a re-coat. If it's a crusty white bloom in the stone mortar joints, that's efflorescence, mineral salt leaching from inside the material, and it can come back after a freeze-thaw cycle regardless of washing.
Most Alpine Pointe homes hold up well on an annual wash, since this pocket doesn't get the constant fresh graded-lot silt that hits the active-construction edges of south Meridian. The exception is a wall that backs directly onto a rotor sprinkler zone — those streak faster and can be worth washing twice a year. Quarterly membership customers get it handled automatically with no extra call needed.
Same soft-wash pass, same low pressure, but we work the stone a little longer since mortar joints hold onto grime and mineral streaking more than a flat stucco surface does. It's all one visit and one square-footage price — we're not charging separately to treat the stone differently, we're just spending the time it actually needs.
Soft-wash house washing is $0.18 a square foot, priced off the home's actual exterior square footage, so a bigger custom plan with more wall area runs more than a smaller one. We'll give you a firm number on-site and call out anything that's chalking or efflorescence rather than surface dirt before we start, since that's not something a wash can fix.
