Norterra's paired homes sit on small HOA-maintained lots off Highway 44 near Can-Ada Road, which puts sprinkler heads closer to the foundation than they'd ever sit on an acre lot in Star. That distance is the whole story on hard water spotting here, and it's why two Star subdivisions a mile apart look nothing alike.
On a half-acre Star lot, a sprinkler head is usually far enough out that overspray breaks up before it reaches glass. Norterra doesn't have that room. The landscape strips between the foundation and the drive or walk are narrow, so the heads that water them sit within a few feet of the wall, and a fixed spray pattern that's off by even fifteen degrees puts untreated water directly on ground-floor windows every cycle. We see that as a hard band of spotting across the lower third of a pane with clean glass above it — the signature of a head shooting flat rather than a wind-carried mist. That band is the tell we look for first, because it points at one head, not at the whole system, and one head is a cheap fix for the homeowner or the HOA.
Norterra's front and common-area landscaping is HOA-maintained, which changes who can fix the cause. If the spotting is on your street-facing lower windows and the offending head is in a common bed or the strip along a shared drive, adjusting it is a management-company request, not something you or we should be twisting by hand. If the spots are on the back slider or patio glass, that's usually your own zone and you can turn the head down yourself in about a minute. We tell you which side of that line the head falls on when we quote, because there's no point paying to restore glass twice a year while the same head keeps painting it. Homeowners who get the aim corrected typically go from a hard annual restoration to a light touch-up.
Star runs on pressurized irrigation drawn from canal water, not from the treated line that feeds the house. It's fine for grass and it's loaded with dissolved calcium and silica. When it hits a warm south- or west-facing pane and flashes off in the afternoon, the water leaves and the minerals stay welded to the surface. That's why hose water rinsing never fixes it and why a squeegee pass just smears the top layer. Removing it takes a mild abrasive polish worked over the deposit until the glass reads clear again, then a full rinse. It's a slower, more physical job than a routine wash and it is priced separately for that reason — quoted by severity after we look at it, because two windows on the same wall can need very different amounts of work.
This matters more than anything else on the page. Norterra was built in Star's newest construction wave, so the irrigation systems here have been running a handful of seasons, not twenty-five. Mineral deposit sits on top of the glass at first and can be polished away completely. Left long enough, the silica works into the surface and etches it, and etched glass is permanently hazy — no product, no pressure, and no amount of scrubbing brings it back. Replacement is the only fix at that stage. Because most Norterra glass is still in the deposit stage rather than the etched stage, this is the cheap window to deal with it. We'll tell you honestly if a pane has already crossed over instead of charging you to polish something that won't improve.
Hard water stain removal is quoted by severity — a light haze on four ground-floor panes and a five-year buildup across a whole elevation are not the same job, and we won't pretend they are. On a Monthly membership it's included, which is the sensible route in Norterra because keeping spotting from accumulating is far less work than removing it once it's set. Our regular window work uses 100% pure deionized water with no soap, so nothing is left on the glass for the next irrigation cycle to bond to.

Run a fingernail lightly across a spotted area. If you feel raised texture, that's deposit sitting on the glass and it polishes off. If the surface feels smooth but still looks cloudy, the mineral has etched into it and no cleaning will bring it back. Most Norterra homes are new enough to be in the first category, but we check pane by pane before quoting.
Take a photo of the head and the spotted window and send it to your management company as a maintenance request — an off-aim head watering a wall instead of a bed is a legitimate work order, not a favor. We can point out exactly which head is doing it when we're on site. Adjusting a head you don't own isn't something we'll do without the HOA's say-so.
Direct overspray from a close-set head hits ground-floor glass in a defined band. Upper-floor spotting usually means wind-carried mist from a rotor or a high-arc head reaching farther. End units with more open exposure catch more drift than interior units boxed in on both sides, so two Norterra homes on the same street can genuinely have different patterns.
No. Our standard service uses pure deionized water and a squeegee, which removes dust, pollen, and film but not bonded mineral. Hard water removal is a separate abrasive polishing process, quoted by severity. It's included on the Monthly membership. If you book a standard clean and we find real hard water staining, we'll flag it rather than charge you for a wash that won't fix it.
With a head still hitting the glass, expect visible spotting again within one irrigation season — roughly April through October in Star. Corrected aim usually pushes that out to normal maintenance intervals. That's why we push the aim fix first. Paying to restore the same window every year while the cause runs untouched is the expensive way to do it.
Sometimes, with different methods — stone and stucco take a soft-wash approach rather than glass polishing, and porous surfaces don't always release mineral completely. We'd rather set that expectation upfront than promise a full recovery on masonry. We'll look at the material and tell you what improvement is realistic before doing anything to it.
