Hillcrest went in before HOAs ran anybody's sprinklers, so every lawn off Latah or Curtis got its own system, installed and re-aimed by a different owner every decade. That is why one ranch on the block has clean glass and the house two doors down has a picture window etched white across the bottom third.
In a newer subdivision with HOA-run common landscaping, a whole row of homes shares one controller and one set of rotors, so the damage is uniform. You can quote the street. Hillcrest is the opposite. These blocks were built between roughly 1952 and 1965, long before anyone standardized a sprinkler layout, and the systems went in piecemeal over sixty years. Some lots still run brass impact heads on galvanized pipe from a 1970s retrofit. Some got a full spray-head system in the 90s. Some are still hose and a tripod sprinkler set wherever the grass looks dry. That is why we walk the property before quoting instead of pricing off the address. Two identical ranches on the same street can be twenty years apart in etching severity.
This is the part people miss on the Bench. On a two-story house only the ground floor glass gets hit, and the upstairs stays clean. A Hillcrest ranch has all of its glass sitting four to six feet off grade, so a head throwing fifteen feet from the middle of the lawn puts water on the picture window, the bedroom sliders, and the kitchen unit over the sink all at once. Then the eaves make it worse. There is only a few inches of overhang on a 3:12 roof, so nothing shields the pane and nothing rinses it either. West and south elevations take the worst of it because afternoon sun bakes the droplet dry in minutes and the mineral concentrates instead of running off. North-side glass on the same house often cleans up easily.
Plenty of Bench lots pull irrigation off a lateral rather than the house meter, and that water is a different animal. It carries suspended silt on top of dissolved mineral, so you get a gritty tan film that hides the etch underneath until we clean it. Sprinklers running on Boise city water leave a cleaner white deposit that is easier to read but no softer. Either way, the mineral only becomes permanent when it dries in place repeatedly on the same square foot of glass. The stain that shows up along the bottom rail of a picture window is not one bad summer, it is a head that has been clipping the same spot every other morning since somebody set the controller and stopped thinking about it.
Before you pay anyone, do this yourself. Wet the stained area with a spray bottle and look at it while it is soaking wet. If the haze disappears and comes back as it dries, the mineral is sitting on the surface and it will come off. If the cloudiness is still visible with water on it, the mineral has bitten into the glass and you are looking at etching, not deposit. Etching gets improved, not erased. We can usually pull it back to where the window reads clear from inside the room, but on badly pitted glass there will be a haze at a low sun angle and we will tell you that before we start, not after. Anyone promising a perfect result on stage-three etching has not looked at the window.
We start with the least aggressive thing that works: an acid-free mineral dissolver and a soft pad, worked wet, tested on one pane first. If that lifts it, we are done. If it does not, we step up to a cerium polish on the affected section, which is slower and priced accordingly. Old single-pane aluminum units get a lighter hand because that glass is thin and often already carries fabricating debris. We finish the whole window with 100% pure deionized water so nothing we use to rinse leaves a new spot. Hard water stain removal is quoted by severity after we see it, and it is included on the Monthly membership. We also handle the mineral runoff staining on brick wainscot and concrete under the same heads, using standard soft-wash methods rather than glass chemistry. Call (208) 453-6760.

Same water, different sprinklers. Hillcrest has no HOA common system dictating head placement, so your spray pattern is whatever the last owner set. A head aimed two degrees higher than your neighbor's, or one that lost its nozzle screen and started misting, is the whole difference. We usually find one or two culprit heads on a property, and the etching maps back to them exactly.
Yes, if the head that caused them is still aimed at the glass. Removal is the expensive half of the job and re-aiming is the free half. When we finish we point out which heads are hitting the house and roughly where they need to sit. Fix that and the glass stays clear for years. Skip it and you are buying this service again in two or three seasons.
Sometimes, partially. That glass is thinner than modern float and often has fabricating debris in it already, so heavy polishing carries a real risk of leaving a faint lens-like waviness. We test one pane, show you the result, and let you decide whether to run the rest. If the honest answer is that the window needs replacing rather than restoring, we say so and you owe us nothing for looking.
On a small bathroom lite with severe etching, occasionally yes. On a wide Hillcrest picture window it is almost never close, because replacement means a glass shop, a crane-free two-man set, and often a frame that no longer has a matching profile. Restoration on that size unit is a fraction of the cost. We will give you a straight comparison rather than talking you into the bigger job.
Turn the zones facing the house off for the day of service and the day after, that is all. Freshly polished glass is clean and slightly more absorbent for a short window, and you do not want a 5 a.m. cycle laying new mineral on it. If your controller is confusing, leave it and tell us which zone covers the front lawn. We will work around the schedule.
It is. On Monthly we handle spotting as part of the regular visit, which is the cheap way to do this because deposit that gets caught early never becomes etching. Quarterly and one-time jobs get stain work quoted separately by severity. No contract on either plan, every visit carries the 7-Day Rain Guarantee, and we usually have same-day or next-day slots open on the Bench.
