On Star River Ranch's acreage lots, sprinklers are not the little pop-up sprays a quarter-acre subdivision runs. They're long-throw rotors covering a half acre or more of lawn, and the tail end of that throw lands on the house. That's why the river-facing glass out here etches while the front of the same home looks fine.
Hard water damage is the least uniform thing we deal with, and Star proves it. Two homes a mile apart can have wildly different glass depending on one question: where does the sprinkler water come from? Lots pulling from a private well on the river bottom are throwing dissolved mineral straight onto the siding and glass — that's the water that etches. Lots on pressurized irrigation are throwing untreated surface water, which is siltier but generally softer, so it leaves a gritty film that scrubs off rather than a bonded mineral deposit that doesn't. Same neighborhood, same rotors, two entirely different repair jobs. Before we quote anything in Star River Ranch we ask what feeds your system, because that answer changes whether you need a cleaning or a restoration.
On a big lot, rotor heads sit far enough back that the last few feet of arc is a fine mist, not a stream — and mist is worse for glass than a direct hit. A stream runs off. Mist beads, sits, and evaporates in place, leaving every mineral behind. We find the damage concentrated in a band across the bottom third of ground-floor windows on whichever elevation faces the biggest stretch of lawn. On most Star River Ranch homes that's the back, facing the river or the community lake, because that's where the open turf is. West and south elevations take it hardest of all: afternoon sun dries the droplets before they can run, which concentrates the mineral instead of diluting it. North-facing glass on the same house is often untouched.
If your lot backs or fronts common ground — lake path, entry landscaping, shared green space — you have a second irrigation system aimed at your house that you don't control and can't reschedule. Those common-area zones tend to be older, set on longer run times, and nobody walks them looking for a head that's drifted out of alignment over a few seasons. A single misaimed rotor on common ground will etch one homeowner's windows badly while the neighbor two doors down has clean glass. We can usually tell which it is from the stain pattern: your own heads leave a repeating arc-shaped band, while a stray common-area head leaves a lopsided cone on one corner of the house. If it's the common system, that's an HOA conversation, and it's worth having before you pay to restore the same glass twice.
Here's the honest part. Wet the spot and drag a fingernail across it. If it disappears when wet and comes back dry, it's surface mineral — that comes off with a proper restoration. If you can feel texture under your nail and it still shows when wet, the mineral has already eaten into the silica and you're looking at pitting, not a deposit. Pitted glass does not return to new. We can take it from cloudy back to mostly clear, but we're not going to tell you it'll look like a fresh pane, and we'll say so before we charge you rather than after. Years of untreated overspray on a west-facing window is the case where we sometimes tell people that replacement is the better use of their money.
Restoration is quoted by severity because a two-season film and eight years of baked-on rotor mist are not the same job. Once the glass is back, we finish in 100% pure deionized water so there's no soap residue and no mineral of our own left behind. The prevention side is simple and free: walk your heads in April when the irrigation season starts and again mid-summer, and move or throttle anything that's misting the house. If you're on Monthly membership, hard water treatment is included, which matters here because the etching clock only runs from irrigation turn-on to shutoff — catching it inside one season is the whole game.

Because the back is where your lawn is. On Star River Ranch acreage lots the big rotors are aimed across the open turf toward the river or lake side, and the far edge of that spray drifts onto the house as mist. The front yard usually runs shorter throws farther from the wall, so that glass never gets hit the same way.
Depends on whether it's deposit or etch. Wet it — if the cloudiness vanishes while wet, it's sitting on top of the glass and it comes off. If you can still see it wet and feel texture with a fingernail, the mineral has pitted the surface and no amount of scrubbing brings it fully back. We'll tell you which one you have before we quote it, not after.
It matters more than anything else. Well water on the river bottom carries dissolved mineral that bonds to glass and etches. Pressurized irrigation is surface water — siltier, so it leaves a dirty film, but usually much less aggressive on the glass itself. Same sprinkler pattern, different damage. Tell us which one feeds your system when you call and we can give you a much better read over the phone.
We can restore the glass, but we can't re-aim a head we don't own. If the stain shows up as a lopsided cone on one corner rather than a repeating band across the back, that's usually a common-area rotor that drifted out of alignment. Worth raising with the HOA before paying to restore the same windows again next fall.
Late fall, after irrigation shutoff, is ideal — the damage is done for the year and nothing re-sprays the glass over winter. Early spring before turn-on is the second-best window. Mid-season restoration works too, but if the head that caused it hasn't been moved, you'll be adding new mineral over the clean glass within a couple weeks.
It's quoted by severity rather than a flat rate, because a light seasonal film and eight years of baked-on rotor mist take completely different amounts of work. On a Monthly membership it's included. Either way we look at the actual glass first and give you a firm number, and we'll tell you if a window is too far gone to be worth restoring.
