Sunnyvale sits in Nampa off W Karcher Rd near Caldwell Blvd in 83651, and it is new ground: recorded 2020–2025 across 6 phases, with homes still going up. At roughly 84 acres and about 300 lots it is a mid-sized pocket. The glass problem is untreated canal water through the irrigation line: mineral-heavy, and aimed at the house by whoever set the sprinkler heads.

Two separate water supplies reach a Nampa window and both of them are hard. The first is the City of Nampa's groundwater — all of it pumped from the city's own wells, and reported as hard as about seven grains per gallon. The second, and the one that actually does the damage, is Pioneer Irrigation District and Nampa & Meridian Irrigation District — untreated surface water delivered to the sprinklers, carrying suspended silt and dissolved calcium and magnesium straight off the canal. When a head clips a pane the water sheets, evaporates fast in the valley's dry air, and leaves the silt as a gritty film and the mineral as a bonded ring. Soap moves the first around and does nothing to the second. We run 100% deionized water instead — stripped of its own minerals, it pulls the deposit into solution and dries leaving nothing behind to catch the next round.
Sunnyvale is still filling in, and glass on an active build site carries what a finished neighborhood never sees: concrete and mortar splatter, stucco slurry, drywall compound dust and cut-masonry fines. Those are alkaline and mildly abrasive — the worst combination there is, because wiping them with a soapy cloth grinds them across the pane and leaves fine scratching no later cleaning removes. There is usually label adhesive in the corners too. We soften and lift residue rather than scraping dry glass, and we check for tempered stamps before any blade goes near a pane.
Nampa sits in the middle of working Canyon County farm ground, and that is the difference between glass here and glass in Boise. Field dust is not an occasional nuisance; it is a seasonal certainty, and it arrives while the irrigation is still running. Every city in the valley gets dust. Nampa gets harvest. From the first disking in spring through the onion and sugar-beet lift in the fall, there are weeks at a time when the air carries a genuine load of field silt, and it does not settle politely — it arrives on a west wind and it arrives while your irrigation is still cycling. Dust landing on dry glass rinses off. Dust landing on a pane still damp from a sprinkler bonds into the mineral film and stops being dust at all. That is why a Nampa window cleaned in August can look untouched by the end of September, and it is an argument for timing the work to the harvest calendar rather than the human one. We would rather clean your windows in late October, after the lift, than in early September and watch it undo itself.
Traditional window cleaning puts soap on glass and then tries to remove all of it. What stays behind is invisible on the day and obvious a fortnight later, because it is tacky and it collects. Deionized water skips the problem: no surfactant goes on, so none is left. The practical result is a longer interval between cleanings and no streaking in the raking light that shows up every other method.
Pane count drives the number, not house size — a small home with forty divided lites takes longer than a large one with twelve big panes. Exterior starts at $199, gutters at $199, house washing $0.18 a square foot and pressure washing $0.20, and hard water work is per affected pane once we have tested. Nothing is on contract.
We will walk your irrigation heads with you and show you which ones are clipping glass. Mineral that never lands is mineral we never have to remove, and a customer whose windows stay clean longer calls us back. Where glass sits in an unavoidable spray pattern a sacrificial sealant is worth discussing, and we will be straight that it wears off rather than lasting forever.

The irrigation water, nearly every time — Pioneer Irrigation District and Nampa & Meridian Irrigation District delivers untreated surface water to the sprinklers, and it carries silt and dissolved mineral that treated water does not. Any head throwing onto a pane leaves both behind every cycle. The fix is part cleaning and part aim: we will show you which heads are hitting glass.

Exterior window cleaning starts at $199, priced by pane count rather than square footage, because panes are what take time. Interior is quoted the same way. Screens are a $50 add-on alongside a window service. Hard water stain removal is quoted per affected pane after we test one. No contract.
Not necessarily. Construction fines are alkaline and mildly abrasive, and the longer they sit through irrigation cycles the harder they bond. The first proper cleaning after your own build finishes is worth doing even if the lot across the street is still active.
Wherever the elevation allows, yes. Carbon-fiber water-fed poles reach most second-story glass from the ground, which keeps ladder feet off landscaping and off the roof. Where a pole will not do a clean job we ladder it properly. We do not do rope-access or high-rise work.
