Window Cleaning in Roberts and Hill, Boise, Idaho

What the Water Leaves on Roberts and Hill Glass

The mineral on Roberts and Hill glass does not come from the sky. It comes from the New York Canal system and the Boise Project, which delivers untreated surface water to the sprinklers on a separate line, and it is compounded by treated river and well water that is hard by any standard, which is why fixtures here scale even where sprinklers never reach the glass. Every irrigation cycle that reaches a window deposits a little silt and a little dissolved mineral, and every evaporation concentrates what is already there. Over a season it bonds; past that it begins to etch the glass itself. This is why an ordinary wash looks fine on the day and hazy again within weeks — the deposit was never removed, only wetted. Deionized water dissolves it rather than redistributing it.

Original Glass in Roberts and Hill, Handled Accordingly

Plats this old came with mature trees, and that changes the soiling as much as the age of the glass does. Alongside mineral, Roberts and Hill 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.

Foothills Grit and the Winter Inversion

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.

Screens Are the Usual Culprit

A screen is a filter and it has been doing its job all summer. Silt dries in the weave and greys the whole view, so a perfectly clean pane behind a loaded screen still looks dirty. We would rather you added screens to the booking than paid for a window clean and felt it had not worked.

Frequency, Honestly

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.

Why There Are No Streaks, and Why It Lasts Longer

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.
