Bayhill's sprinklers went in with the subdivision starting in 1998, and twenty-eight years of settling heads and grown-in landscaping have quietly re-aimed a lot of them. Add the HOA's rotors around the ponds and entry waterfall, and hard water damage here varies house to house, not street to street.
Bayhill went in starting in 1998, and the irrigation went in with it: late-90s impact and early rotor heads, spaced and aimed for turf that was brand new and shrubs that came out of one-gallon pots. Twenty-eight years later that landscape is grown in. Plantings block an arc and kick the stream sideways into a wall. Heads settle, get clipped by mowers, or frost-heave a few degrees off plumb, and a rotor tilted ten degrees toward the house will put water on glass every single cycle without anyone noticing, because it runs at four in the morning. That is why hard water damage in Bayhill is a house-by-house problem instead of a street-by-street one. Two homes on the same block, same builder, same year, can be a decade apart in etching depending on which heads drifted.
Your lot's zones run on your controller, on your schedule, and you can shut a head off tomorrow. The common landscaping does not work that way — the entry, the waterfall bed, and the turf and plantings ringing the ponds and stream corridor run on the association's controller with bigger rotors, longer throw and pre-dawn start times set for coverage, not for the houses on the perimeter. If your home fronts a common-area strip or backs the pond turf, you are taking mineral spray you did not schedule and cannot reschedule. We note it on the estimate — which head, roughly where it sits, and which direction it is throwing — so you have something specific to hand the HOA instead of a general complaint about sprinklers.
Most of Nampa, Bayhill included, waters off the pressurized irrigation district rather than the tap: untreated surface water out of the canal system, carrying suspended silt on top of dissolved mineral. The silt is the abrasive and the mineral is what bonds it down, which is why irrigation spotting cuts deeper than an occasional rinse with Nampa's roughly 7-grain city water. On a Bayhill lot the pattern is predictable once you know where the turf sits. The front elevation collects it on entry sidelights and the picture window, the pond-side rear takes it across the great-room window wall, and narrow side yards get the heaviest concentration in the bottom three or four feet because the head sits close to the wall on a low arc. First floor is almost always worse than second. A spotted second-story window means a rotor is over-throwing, and that is a repair, not a cleaning problem.
Stage one is surface deposit. You can catch it with a fingernail, and it strips with an acid gel and a pad. Stage two is bonded scale that has been through a few summers — longer work, sometimes two passes, but the glass comes back clear. Stage three is etching: the mineral has pitted into the silica and there is nothing left to remove. No chemical, no pressure washer, no amount of scrubbing brings that back, and anyone who tells you otherwise will charge you and hand back the same window. Tempered glass reaches stage three fastest — patio sliders and the big fixed panels near doors — because the tempering furnace leaves a rougher surface that holds mineral. We test one corner panel and tell you what stage you actually have before we quote the house.
Hard water stain removal is quoted by severity rather than by pane count, because a stage-one window and a stage-two window on the same house are completely different amounts of labor. We test a panel, show you the result, and price from there. It is included on the Monthly membership, which is the right structure for a Bayhill home taking common-area overspray it cannot switch off — the point is keeping glass from ever reaching stage two. No contract, cancel anytime, 7-Day Rain Guarantee. Once the glass is stripped we clean it with 100% pure deionized water and no soap, so nothing we leave behind spots it again.

Almost always one misaimed head. Bayhill's systems all went in around the same time, but twenty-eight years of mowing, settling and grown-in shrubs move heads a few degrees at a time. A single rotor tilted toward a wall will hit the same glass every cycle for years while the identical house next door never gets touched. We walk the zones and tell you which head to look at.
Maybe not. Sliders and large fixed panels are tempered, and tempered glass has a rougher surface from the furnace rollers, so it grabs mineral harder and etches sooner than the annealed glass in a standard window. If the haze is still sitting on top, we strip it. If it has pitted into the glass, no product removes it, and the honest options are living with it or replacing the panel. We test a corner before quoting.
You do not have to, but if you skip it the stains are back within a season and you have paid twice. Cleaning removes the deposit; it does not touch the source. Most Bayhill fixes are small — rotate the head, drop the arc, change a nozzle, straighten one that has heaved. We flag the specific heads on the estimate so you or your irrigation guy can handle them before the next visit.
The association does, but you have to be specific or nothing happens. "Sprinklers hit my windows" gets filed. "The third rotor east of the pond path throws onto our north elevation past the twenty-foot mark" gets fixed. We record the location and throw direction on your estimate so you have something concrete to submit. We can clean the glass either way — it just comes back faster until that head gets moved.
Probably not. Bayhill's original vinyl windows are now 25 to 28 years old, right in the range where insulated glass units start losing their seal, and that haze sits between the two panes where nothing external reaches. Cleaning both faces changes nothing. The fix is a replacement insulated unit from a glass shop. We will tell you when that is what we are looking at instead of charging for a stain we cannot get to.
Late April or May, right after the pressurized system turns on. That first flush is the siltiest water of the year and it lands on glass that has sat clean all winter. Getting the existing scale off then, and fixing whatever head is doing it, gives you a full season on stripped glass instead of chasing it in September when it has baked through three months of heat.
