Eagleson Park sits in Boise between Orchard and Federal south of Overland in 83705, and it is a long build-out — the plats run 1910–1938 across 4 phases, so the housing stock spans a decade or more. It covers about 120 acres, large enough that we route it as its own stop. The glass problem is untreated irrigation water off the canal system: mineral-heavy, and aimed at the house by whoever set the sprinkler heads.

Ask anyone in Boise why their windows spot and the honest answer is the sprinklers. the New York Canal system and the Boise Project supplies untreated canal water to the irrigation line, and it is carrying both silt and dissolved mineral. On glass that dries into a ring you can see in low sun and feel with a fingernail. The culinary side does not help either — treated river and well water that is hard by any standard, which is why fixtures here scale even where sprinklers never reach the glass — so rinsing with a hose adds mineral rather than removing it. Pure water with no soap is the only method that takes the deposit off instead of smearing it and leaving a tacky film for the next cycle to stick to.
Plats this old came with mature trees, and that changes the soiling as much as the age of the glass does. Alongside mineral, Eagleson Park homes get sap, pollen and leaf tannin staining, plus shade that keeps north elevations damp long enough to grow something. The windows are frequently original — softer glass, early frames, putty gone hard — so we adjust method to condition rather than running a new-build process.
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.
Some jobs are not ours. Anything above three stories needs a rope-access specialist. Failed seals, broken glass and rotten frames need a glazier, not a cleaner. Etched glass needs replacing. We would rather point you at the right trade than take the booking and under-deliver.
Homes here carry tall glass packages — two-story great-room windows, stairwell glass and wide sliders, usually concentrated on the back elevation where no step ladder reaches. Upper glass comes off the ground with poles and pure water wherever it can. That keeps ladders off soft ground and out of beds — most of the damage a window cleaner does to a property is done by ladder feet, not by anything on the glass. We stop at three stories; above that you want a rope-access specialist.
Exterior service covers the glass, the frame and the exterior sill. Tracks are where irrigation silt actually accumulates — it washes down the pane, settles in the bottom track and sets up like thin grout over a season. We clear that rather than cleaning the glass above it and leaving the track packed. Screens hold the same silt in the mesh, which is why a freshly cleaned window behind a dirty screen still reads grey.

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.
