Treasure Valley Marketplace sits in Nampa off N Midland Blvd near Caldwell Blvd in 83687, and it is platted 2005 on one plat — mature landscaping, original windows on most homes. About 75 acres and about 30 lots, compact enough to do several homes in one visit. Most of what you see on these windows arrives as untreated canal water through the irrigation line, and it dries into a ring rather than rinsing away.

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.
Two decades of sprinkler cycles have left most Treasure Valley Marketplace panes with a mineral history rather than mineral dirt, and only one of those comes off. A deposit that has bonded but not yet etched responds to a dedicated dissolver and mechanical work; glass that has etched has lost surface and no product restores it. We check before quoting rather than after, and where a pane is gone we say so.
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.
Twice a year suits most homes here — once after the spring dust and pollen, once at the end of the irrigation season when the mineral load is highest. Homes with glass directly in a sprinkler pattern want the more frequent end of that until the heads get adjusted. Homes whose glass is shielded can often go annually. We are not going to sell you a quarterly plan you do not need.
Floor plans in Treasure Valley Marketplace keep most glass within one or two stories, with the taller panes generally on the rear elevation. Water-fed poles do most of it, and the advantage is not only safety — rinsing at height with deionized water means the top of the pane gets the same treatment as the bottom, which is not true of a squeegee reached out from a ladder. Where the elevation will not allow a pole we set ladders properly, on levelled feet, with landscaping protected. We do not take on rope-access work.
Winter changes the soiling rather than stopping the work. It is a good time to have glass done, because nothing new is being deposited and the result holds until spring start-up. What we will not do is pretend a cleaning fixes condensation: fog on the inside is a humidity problem, and fog between the panes is a failed seal.

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.
Hold a wet finger against it. If the haze disappears where it is wet and returns as it dries, it is deposit and it can come off. If it stays visible while wet, the mineral has etched into the silica and cleaning will not remove it. We test a single pane before quoting so you are not paying to find out.
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.
