Old Nampa's grid was platted decades before pressurized-irrigation subdivisions existed. Every sprinkler system in the historic district was retrofitted onto an existing lot, house by house, era by era. That is why one bungalow on 9th Street South has clean glass and the house two doors down has a hazed west elevation.
In a 2005 subdivision, one contractor installed every yard on the street the same week with the same heads on the same spacing, so a whole block etches at roughly the same rate. Old Nampa has none of that. There is no HOA running common landscaping, no builder-standard sprinkler package, and no single install date. Some of these yards were still hand-watered in the 1980s. Some got a DIY system in the 90s with fixed spray heads planted wherever the trencher could get through the roots of a mature silver maple. Some got a proper rotor system last decade. We have walked two homes on the same avenue where one had light surface spotting and the other had three years of hard etch on the same elevation. So we quote by severity after looking at your glass, not off a neighborhood average.
The historic lots are deep and narrow, and the houses sit close to the street with tight side yards — often eight to twelve feet to the property line. A head set to cover that strip has nowhere to throw water except the house. That is why side elevations on these homes take more mineral damage than the big front picture windows, even though the front gets more attention. Front porches and their deep overhangs actually shield a lot of the street-facing glass. The other pattern we see: parking strip and boulevard heads between the sidewalk and the curb, aimed back toward the yard, catching the low front windows on the return arc. And south and west glass is always worse, because the afternoon sun bakes the droplet dry before it can run off, which is what concentrates the minerals into a ring.
Nampa's core sits in Pioneer Irrigation District territory, and some of these older properties still carry gravity ditch rights off the canal system while others water off city well water tested as hard as 7.08 grains per gallon. They do not stain the same. Ditch water carries suspended silt along with the dissolved minerals, so it dries into a gritty film that hides the etch underneath — homeowners often think it is just dirty until we clean it and the haze stays. City well water leaves the classic clear mineral ring with nothing on top. Both are removable at the early stages. The reason it matters is diagnosis: we need to know whether we are removing a deposit sitting on the glass or a deposit that has already eaten into it, and a silt film makes that call impossible until the surface is clean.
Hard water damage runs a range. Early on the minerals sit on the surface and lift with a proper restoration treatment. Left through several summers, the alkaline deposit etches a pit into the silica and there is no product that fills a pit back in — it has to be abraded down or the pane replaced. Our field test is simple: clean the glass, wet it, and run a fingernail across the ring. If you can feel a lip, it is etched, not deposited, and we will tell you that before you pay for anything. The Old Nampa wrinkle is that a lot of this glass is original wavy single-pane. Aggressive polishing on antique glass can leave an optical distortion worse-looking than the stain, so on true historic sash we work conservative and stop early rather than chase the last ten percent.
Removal is a one-time repair. If the head that caused it is still aimed at the house, you are buying the same job again in two summers. Before we leave we walk the elevation with you and point out which head is doing it — usually one or two, not the whole zone — and most of the time the fix is a fifteen-degree adjustment or swapping a fixed spray for a strip nozzle. That is your work, not a service we sell. Pricing is quoted by severity, because a light surface film and a three-year etch are not the same job. Hard water stain removal is included on our Monthly membership, which also keeps the glass on a rhythm so a deposit never gets the time it needs to etch. No contract, 7-Day Rain Guarantee, same-day and next-day slots when we have them.

Almost always the sprinkler system, not the water. In Old Nampa every system was retrofitted separately across different decades, so head type, spray arc, and aim vary house to house with no HOA or builder standard behind them. One fixed spray head clipping a west window twice a day will etch that pane while an identical house next door with rotors aimed at the lawn stays clean for years.
Usually, but we work conservatively on historic sash. Antique glass has surface irregularity that modern float glass does not, and aggressive polishing can leave a distorted patch that reads worse than the stain did. We remove what lifts safely, then stop and show you what is left rather than pushing until the pane goes cloudy. We also keep compound off failing glazing putty lines.
Clean the glass, wet it, and drag a fingernail across the stain ring. Smooth means the minerals are still sitting on the surface and restoration will take them off. If you catch a lip or feel texture, the deposit has pitted into the glass and no chemical fills that back in — the options become abrasive work or replacement. We run this test in front of you before quoting.
Yes, if the sprinkler head that caused it is still aimed at the house. Removal fixes the glass, not the source. We will point out the specific heads doing the damage before we leave — it is usually one or two per elevation, and often a small aim adjustment or a strip nozzle solves it. Homeowners who make that change generally do not need this service twice.
On a heavily etched modern window, sometimes replacement is genuinely cheaper than restoration and we will say so. On original 1900–1940 wood sash it is a different calculation, because matching period glass and re-glazing a historic sash costs real money and you lose original material permanently. On these homes we lean toward restoring what is there and living with a slight remaining haze.
It is quoted by severity — a light seasonal film and a multi-year etch are different amounts of labor, so a flat number would be a guess.
