Collister went up before pressurized irrigation districts were standard, so no two yards here water the same way. Every sprinkler system on these blocks was retrofitted by a different owner in a different decade. That is why one ranch on Collister Drive has clear glass and the house behind it has a picture window you cannot see through.
Most of this neighborhood is 1950s through 1970s tract, built when a lawn got watered with a hose and a sprinkler you moved by hand. There is no HOA out here running a common mainline, no shared pump station, no district schedule covering every lot on the block. Underground systems went in later, one house at a time, whenever an owner decided to spend the money. That is the whole reason etch severity swings so hard from address to address. A yard piped in 1984 usually still runs brass impact heads on tall risers throwing a flat thirty-five-foot arc. A yard redone in the last ten years is on rotary nozzles with a matched precipitation rate and heads set back off the foundation. Same water, same soil, same sun, completely different glass after twenty years.
A Collister ranch has an eight-foot plate and maybe a two-foot overhang, so every window in the house sits in the strike zone of any head throwing above three feet. On a two-story you lose the ground floor and the upstairs stays clean. Here there is no upstairs to protect anything. The elevations that take the worst of it are west and southwest, and it is not because they get more water. It is because the glass is already hot when the water lands. A droplet on a shaded north pane sits and runs off. The same droplet on west glass in August flashes off in seconds and leaves everything dissolved in it concentrated in one spot. Stand back from a picture window and you can usually read the arc: heavy at the corner nearest the head, fading across the pane.
Plenty of the older lots along the canal still hold ditch rights and take water on a rotation, which means you get your turn when the rotation gives it to you. Sometimes that is two in the afternoon in August, the worst possible time for water to land on glass. Ditch water is also untreated, so along with the mineral you get silt and algae. It dries as a tan or greenish film with hard white spotting set underneath it, and that film has to come off before anyone can see what the mineral actually did. Systems drawing off city tap are a different problem: clean water, no film, but the west side of Boise runs hard, and a timer that could be moved to four in the morning almost never is. Cool glass and early water cuts the damage either way.
Here is a test you can run before we ever get there. Wet the glass and look at the spot while the water is still on it. If it disappears under the water and returns as the pane dries, the mineral is sitting on the surface and a restoration pass takes it off. If you can still see it clearly while the glass is flooded, the deposit has etched into the silica, and that is damage rather than dirt. Nothing dissolves it back out. Polishing can improve badly etched glass, but it removes material and can leave visible distortion in low sun, so on a big picture window we will usually tell you replacement beats a cosmetic fix you notice every evening. We run that test at the quote and tell you which panes are worth paying for.
Hard water work is quoted by severity rather than pane count, because two windows the same size can be twenty minutes apart in labor. A first-season film comes off fast. Fifteen years of impact-head spray on a west picture window is a different job. It is included on the Monthly membership, and Quarterly is available too, no contract either way. Worth knowing: we wash with 100% pure deionized water, and DI water is what keeps clean glass clean. It will not lift mineral that is already there, so restoration is a separate step and the DI wash follows it. The other half of the fix is the sprinkler. Deflecting a head, dropping a riser, or swapping to a low-angle nozzle is usually a twenty-dollar part, and without it you are paying us to do this again.

Almost always the sprinklers, not the water. Collister has no HOA system and no shared district mainline, so every yard on the street was piped separately and decades apart. One house is on modern rotary nozzles set back off the foundation. The next is still running 1980s brass impacts on tall risers that hit siding, glass and everything between. Twenty years of that difference shows up as etching on one house and nothing on the other.
Yes, and we do it at the quote. We flood a section of the pane and look at the spot underwater. Deposit sitting on the surface vanishes while it is wet. Mineral that has etched into the glass stays visible even flooded. If a window is in that second category we tell you straight out that restoration will not fix it, and we do not charge you to try.
You cannot pick your turn, so the fix has to be on the hardware side. Aim the heads that reach the house off the wall, drop tall risers down, and switch anything throwing at glass to a low-angle or shrub-height nozzle. If part of the yard runs off a tap-fed timer, move that zone to before sunrise. Midday water on hot glass does more damage in one season than early water does in five.
No. Mineral deposit is bonded to the glass, and pressure is just water moving fast. It does not dissolve anything. What it will do is drive water past worn window seals, chew up dried glazing putty on older sash, and strip chalked paint off aluminum frames. We use standard pressure methods on concrete and siding, never as a way to attack spotted glass.
It is quoted by severity, because the labor swing is large. A light first-season film and fifteen years of baked-on spray are not the same job. We look at the panes and give you a number before anything starts. On the Monthly membership it is included. Quarterly and one-off visits get it quoted separately. No contract on either membership, and every visit carries the 7-Day Rain Guarantee.
That depends entirely on whether the sprinkler gets fixed. Leave the head aimed at the house and you will see film again within one irrigation season and light etching within a few. Deflect it and keep the glass on a regular wash and restored panes hold for years. We tell you which heads are causing it before we leave. It is usually one or two, not the whole system.
