Surprise Valley sits in Boise east of Broadway south of Amity in 83716, and it is a turn-of-the-2000s subdivision, recorded 1995–1999 across 6 phases. At roughly 185 acres it is one of the larger communities in the city. The glass problem is untreated irrigation water off the canal system: mineral-heavy, and aimed at the house by whoever set the sprinkler heads.

Two separate water supplies reach a Boise window and both of them are hard. The first is treated river and well water that is hard by any standard, which is why fixtures here scale even where sprinklers never reach the glass. The second, and the one that actually does the damage, is the New York Canal system and the Boise Project — 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 Surprise Valley 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.
Boise glass carries something the rest of the valley does not: foothills grit. Decomposed granite off the slope is sharp and fine, it travels on the afternoon downslope wind, and in winter the valley inversion holds everything else down at ground level with it. Two things make Boise different from the cities west of it. The first is the foothills: decomposed granite is a sharp, fine grit, and on a downslope wind it reaches glass that no farm dust ever would. It is the reason we are careful about dry-wiping anything in the Bench and foothills neighborhoods — grit plus a dry cloth is how glass gets scratched. The second is the inversion. For weeks each winter the valley lid holds particulate at ground level, and it settles as a fine grey film that is not dirt in the ordinary sense and does not rinse off in a rain. Winter is genuinely a good time to have Boise glass cleaned, because the low sun angle shows every bit of it and because pure water does not freeze on the pane at the temperatures we will work in.
There is no single right interval and anyone quoting one without seeing the property is guessing. What drives it here is sprinkler exposure more than anything else. We will tell you what we think after the first visit, and it is frequently less often than people assume.
We do not do rope access or high-rise work, we do not repair or replace windows, and we do not re-screen. We cannot remove etching, and we will tell you when that is what you have rather than selling a polish that will not change it. Reflekt has been operating since April 2025 — a shorter history than some of the companies you will be comparing us to, which is worth knowing when you choose.
Streaks are a soap problem. Surfactant residue left in the corners and along the frame line is what you see when low sun hits a window two days after a cleaning, and it is also what the next dust settles onto. Because we never introduce soap there is nothing to leave behind. The glass sheets water off rather than beading it — the RainShield finish — which is why a pure-water clean measurably outlasts a traditional wash here, and why we can work in direct sun without racing evaporation.

The irrigation water, nearly every time — the New York Canal system and the Boise Project 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.
