Most of the hard water damage we pull off glass in Caldwell Origins came from one or two sprinkler heads, not the whole system. These are current-decade builds south of Homedale Road with young landscaping and heads still aimed where the sod crew first set them. Find the head, and the glass usually comes back.
The first thing we check on a Caldwell Origins call is which water is doing the damage, because it is not always the same water. Most newer Canyon County subdivisions run pressurized irrigation off the canal system, and that is surface water: silty, some mineral, but it mostly sits on the glass instead of bonding into it. Domestic water out of the tap is a different animal, deep aquifer groundwater, genuinely hard, and that is what etches. So a house watering front turf on the pressurized system may show a dusty gray film, while the same house hand-watering new sod off a hose bib in April or October, after the district has shut the pressurized water off for the season, is putting hard aquifer water on those same panes. Two different stains, two different removals.
Caldwell Origins is new enough that most of what we find here can still be taken all the way off. Mineral damage runs in stages: loose surface deposit first, then a bonded layer, then actual pitting down into the glass. A head that has been hitting the same pane for three or four seasons is almost always still in the first two stages, and that comes off clean. A head that has been hitting the same pane for fifteen or twenty seasons, which is what we run into in the older neighborhoods closer to downtown Caldwell, has often gone past what any chemical will fix, and honest work there means telling the homeowner we can improve it but not erase it. Newer subdivisions have the advantage. That advantage goes away if the head stays aimed where it is.
Two houses a block apart in the same subdivision can carry completely different stain loads, and the usual reason is what is watering them. Your own front zone runs fixed spray heads throwing roughly eight to fifteen feet on a timer you control. HOA common landscaping, the entry monument, a greenbelt strip, the planted island at a corner, usually runs rotors instead: thirty feet or more of throw, longer cycles, and nozzles set by a landscape contractor thinking about turf coverage, not about the picture window on the house backing that strip. Lots that back or side onto common ground take real overspray from water nobody in the house controls. Interior lots ringed by other houses mostly only get their own. When we quote here we walk the lot line first for exactly that reason.
Overspray by itself does not etch glass. Overspray plus heat does. Systems on these lots usually run before dawn, so east-facing windows get hit and then sit in shade and cool air long enough to sheet off or dry fairly evenly. West and south elevations are where we do most of the real removal work. A mid-morning or evening cycle on a 95-degree July day flashes off in minutes and leaves the mineral behind, layer on layer, all summer. The other spot that takes a beating in Caldwell Origins is the side yard. Five to eight feet between houses puts a spray head almost against the wall, and every ground-floor window on that side gets soaked each cycle. Go look at those before you look at the front. They are usually worse.
Hard water does not come off with pressure. We get asked to blast it, and blasting it does nothing but drive water into the frame and jamb. Mineral removal is a chemical and mechanical job done by hand, pane by pane, followed by a full rinse in 100% pure deionized water so there is nothing left on the surface for the next cycle to bond to. One caution specific to new construction: entry sidelights, stairwell glass, and anything within a couple feet of a door or floor is tempered, and tempered glass both picks up mineral faster and takes aggressive polishing worse than standard glass because of how its surface comes out of the heat treat. We test a low corner before committing to a whole elevation. Pricing is by severity, and stain removal is included on the Monthly membership.

Look at the shape. Sprinkler damage has an edge: a fan or arc band across the lower half of the pane, heavier toward one side, with a fairly sharp outer boundary where the throw stopped. General dust and rain film is even across the whole pane with no edge. If the stain stops at a horizontal line partway up the glass, that is a spray head, and you can usually stand where the head is and see the line it draws.
Yes, and we see it in Caldwell Origins regularly. Three summers of one head firing hard aquifer water at the same west-facing pane, flash-drying in afternoon heat, does more damage than fifteen years of ordinary rain and dust. Age of the house is not the variable. Age of the sprinkler aim is. The good news is that at three or four seasons it almost always still comes off completely.
If the head is still aimed at that window, yes. We are not going to tell you otherwise. Removal resets the glass, but the same nozzle running the same arc every morning starts building the deposit again the first week. That is why we point out the specific heads before we leave. Fixing a nozzle takes about five minutes and it is the difference between a one-time job and doing this again in two years.
No. We are window cleaners, not irrigation contractors, and we are not going to start turning nozzles on a system we did not install. What we will do is show you which heads are causing which stains and roughly where the throw is landing. From there it is a quick fix for you, your landscaper, or the HOA's contractor if the water is coming off common ground.
We cannot tell you what your CCRs say, but every homeowner we have helped with this has gotten further by documenting it than by arguing about it. Take photos of the stain line on your glass and photos of the rotor mid-cycle so the arc is visible, then send both to the HOA or the landscape contractor. Most of the time it is a nozzle swap or an arc adjustment, not a fight.
It is quoted by severity, not by pane count, because two windows the same size can be twenty minutes apart in labor depending on how many seasons of buildup are on them. That is also why we would rather look at it than guess over the phone. It is included on the Monthly membership. We are locally owned, fully insured, and at 4.9 stars across 115+ Google reviews.
