Mace River Ranch went in through the mid-2000s and 2010s, and the irrigation went in with it — spray heads set close to the foundation on tract-sized lots, fed by untreated canal water. Twenty seasons later, the bottom three feet of glass on the sprinkler-facing elevations shows it.
Most of Mace River Ranch built out between the mid-2000s and the mid-2010s, so the irrigation is roughly twenty seasons old on the earliest phases and about ten on the later ones. That gap shows up on the glass. A head that has been drifting out of alignment since 2006 has laid untreated canal water on the same three feet of window every other morning from April into mid-October — call it six hundred-plus cycles on that pane. A phase that went in around 2014 with pressure-regulated bodies puts far less on the house. Two homes a few streets apart in this subdivision can sit at completely different stages of damage for that reason alone, which is why we quote hard water by severity after looking at the actual glass instead of off a phone call.
Your in-lot system runs fixed spray heads and small rotors set close to the foundation for the beds and the lawn strip. Those are the ones fanning the bottom sash, the sill and the vinyl frame. The HOA's common landscaping — the entry, the pathway strips, the pond and greenbelt edges — runs bigger rotors with a much longer throw, on a controller you have no access to. If a side yard or rear elevation faces common ground, that is the water reaching second-story glass, and it is the source homeowners never check because it isn't on their schedule. When we find mineral film on upper windows of a lot backing common area, the fix isn't your sprinkler. It's a conversation with the HOA's landscaper about arc and run time.
The damage stacks in a predictable order here. West and south elevations are worst, because they take the overspray plus afternoon sun, and heat is what turns a rinseable film into a bonded deposit — it bakes the water off before it can run down the pane. North-facing glass on the same house often comes clean with a normal deionized wash, since that water sat and evaporated slowly. Corner lots take a second hit on the street side from parkway strip heads. Patio sliders catch it low and hard, because lawn rotors aimed back toward the house throw straight across the slab and up the door. We walk every elevation before quoting, and the front of the house is rarely the one that needs the most work.
Run this before you call anyone. Wet the pane and look at it while it's wet. If the haze vanishes under water and reappears as it dries, the mineral is sitting on top of the glass and it will come off. Drag a fingernail across it — ridges or a gritty texture mean deposit, and deposit dissolves. If the glass feels perfectly smooth and the cloudiness is still visible while wet, the surface has been etched and the minerals have leached into the silica. That does not come out with soap, vinegar, a razor, or pressure at any PSI. It needs a mechanical polish with cerium oxide, it takes real time per pane, and on badly pitted tempered glass it sometimes doesn't fully return. We tell you which one you have before you pay for anything.
Hard water is quoted by severity rather than pane count, because a light film and a decade-old etch are different jobs on identical windows. We test a corner of the worst pane first so you can see the actual result before committing the whole house. Restoration is a one-time job; keeping it off is the part that saves money, and hard water treatment is included on the Monthly membership. Afterward we wash with 100% pure deionized water and no soap, so no surfactant residue is left for the next irrigation cycle to bond to. Correct the aim on the offending heads, stay on a rotation, and the glass holds. Memberships are Monthly or Quarterly, no contract, 7-Day Rain Guarantee, and we keep same-day and next-day slots open.

It's almost always irrigation, not water quality — you're both on the same pressurized canal supply. What differs is head placement, spray arc, and how long that system has been drifting out of alignment. An early-phase home with unregulated heads throwing at the house has taken roughly twice the cycles of a home whose system went in a decade later. Sun exposure on the affected elevation is the other half of it.
Yes, and it's the most-missed source in this neighborhood. Common landscaping runs larger rotors with a long throw on a controller you can't touch. If your side or rear elevation faces common ground, a pathway strip, or a pond edge, that water can reach second-story glass — which is exactly why homeowners are puzzled, since their own heads can't get that high. Worth reporting the arc to the HOA's landscaper.
On a light film, an acidic cleaner can work if you're careful. On anything older it usually lightens the top layer and convinces you the rest is permanent when it isn't. The bigger issue is runoff — acid products pit metal frames, dull stone and stucco sills, and haze screen mesh. If you try one, keep it off the frames and rinse fast.
Usually not. Most of what we see in Mace River Ranch is deposit plus light-to-moderate etch, and that polishes out. Replacement is the honest answer only when a pane is deeply pitted, typically older tempered glass that's been sprayed daily for well over a decade. We test a small area first and tell you which category you're in before you spend anything on a full restoration.
No. The polishing compound stays on the glass and gets rinsed completely. We pull the screens first and mask the vinyl sills and frames before starting, because the slurry is abrasive and vinyl scratches easily. If a frame already has mineral film baked around the weep holes, that gets cleaned separately with a method safe for vinyl, not with the glass compound.
Once the glass is restored, the job becomes prevention. Hard water treatment is included on the Monthly membership, which is what we recommend for homes with heads still aimed at the house. Quarterly is enough if the overspray is light or you've had the sprinkler arcs corrected. What you don't want is a full irrigation season untouched — that's how a rinseable film turns into an etch.
