Mason Creek lots run a tenth to a quarter acre, which puts builder-set sprinkler heads within throwing distance of the house on nearly every plan east of Middleton Road. Add untreated irrigation water off the lateral system and you get mineral etching on the same elevations, street after street.
Mason Creek was platted recently enough that every irrigation system in it went in at roughly the same time, to roughly the same builder spec. That matters more than people expect. On a tenth-acre to quarter-acre lot, a rotor throwing 25 to 30 feet covers the whole yard and then some, so the tail end of the arc lands on siding and glass instead of grass. Older Caldwell neighborhoods on half-acre and acre lots have the room to keep heads away from the walls. Here they don't. Walk Noble Way or Armuth Street in the evening and you can watch whole runs of houses getting watered along with the lawn. The upside of a subdivision this uniform is that once we've diagnosed one house on a street, we usually know what the next three look like before we pull in.
Most newer Canyon County subdivisions are set up on pressurized irrigation rather than watering off the house tap, and Mason Creek sits on ground fed by the Mason Creek waterway and the Horton Lateral. If your sprinklers run off that system, the water hitting your windows never went through a treatment plant. It carries dissolved calcium and magnesium the way Caldwell tap water does, plus suspended silt off the ditch. Silt is the part homeowners underestimate: it dries into a gritty film that holds minerals against the glass and gives the next cycle something to bond to. That is why irrigation overspray usually bites deeper in one season than the same number of sprinkler hits from treated water would. Check your valve box. A separate irrigation pump or district connection means you should assume the harder case.
There are two separate sprinkler systems affecting a Mason Creek house and you only control one. Your own heads you can fix in an afternoon: dial the arc back, swap a rotor for a pop-up spray in the narrow side yards, or drop in a nozzle that throws lower and flatter. Common-area landscaping along the Middleton Road frontage, the entry monuments and any shared green space runs on the HOA's clock, usually a longer cycle at a bigger head, and no amount of adjusting your own zones touches it. If your house backs or sides onto common landscaping, the fix is a note to the HOA or its landscape contractor, not to us. We'll tell you which side of the house the damage is coming from when we walk it, and that's worth knowing before you pay to restore glass that's about to get hit again.
Overspray damage doesn't spread evenly across a house. On the Mason Creek plans we see most, the worst panes are the lower halves of west- and south-facing windows: west because the afternoon sun bakes the deposit on before it can evaporate clean, south because that's where the sun sits longest. Bottom sashes and the lower three or four feet of a fixed picture window take the hit, while the upper glass and the two-story stacked windows over the entry are usually fine unless a rotor is badly aimed. The other spot to check is the narrow side yard between houses. Six to eight feet of gap with a head in it means both walls get watered, and those side windows go unnoticed for years because nobody stands in that walkway. Window-well glass on these lots collects runoff too.
Straight answer on the limits. Fresh spotting, one or two seasons old, comes off with the right mineral compound and hand work. Deposits that have sat through several Idaho summers have etched into the glass surface itself, meaning the mineral hasn't sat on the pane, it has eaten into it, and no chemical takes that back out. That case needs mechanical polishing, which we quote honestly, and on badly pitted tempered glass replacement is sometimes the cheaper and better-looking answer. Pressure washing will not do it at any PSI; you'll only drive water past the seal. And our deionized water window cleaning prevents new spotting, it does not dissolve old deposits. Stain removal is quoted by severity after we look at it, and it's included on the Monthly membership. Fully insured, locally owned, no contract.

Faster than most people expect on this system. Untreated irrigation water plus full afternoon sun on unshaded new-construction lots can leave visible marks in a single season, and marks that resist normal cleaning within two. The variable is aim and frequency, not the neighborhood as a whole. One house on Snowyside Way can be badly etched while its neighbor two doors down is clean, purely because of where the heads sit.
Two reasons specific to new builds. During landscape establishment, systems run daily or near-daily through the first season or two to get sod rooted, which is far more sprinkler contact than a mature yard ever gets. And builder-installed heads get set once at install and rarely re-aimed after the fence goes in and the shrubs fill out. A newer house can carry worse etching than a thirty-year-old one down the road.
We can identify it, but we can't adjust it. Common-area heads belong to the HOA and whoever holds the landscape contract, and they typically run longer cycles at higher volume than a homeowner zone. Send the HOA a note with the location of the head and a photo of the affected windows. Restoring the glass before that's handled just means paying for the same work again next summer.
If the sprinkler that caused them still hits the window, yes, usually within a season. Removal is the second half of the job. The first half is a head adjustment or a nozzle swap, and we'll point out exactly which head is doing it while we're there. Once the water stops landing on the glass, deionized-water maintenance cleaning keeps it clear, since no soap or mineral residue is left behind for new deposits to build on.
Not reliably, but you can narrow it down yourself in a minute. Wet the glass with a hose or a soaked cloth and look at it while it's still wet. If the marks vanish and only return as it dries, the deposit is sitting on the surface and usually comes off. If you can still see them clearly on wet glass, the mineral has etched into the pane and it becomes a polishing or replacement conversation.
It's quoted by severity, because a first-season film and a three-year etch are completely different amounts of labor. We look at the affected elevations, tell you which panes are restorable and which aren't, then price it from there rather than guessing off square footage. It's included on the Monthly membership, memberships have no contract, and we run same-day and next-day slots when the route allows. Call (208) 453-6760.
