On BanBury's course-front lots, the sprinklers are the whole story. Every yard here runs on untreated pressurized irrigation, not treated tap, and six months a year those heads throw canal minerals onto the glass. Which elevations get chewed up depends entirely on where your heads sit and how they're aimed.
The water coming out of your sprinklers in BanBury never went through a treatment plant. It comes off the canal system through a pressurized irrigation district, and it carries both suspended silt and dissolved calcium and magnesium straight to your windows. Delivery runs roughly mid-April to mid-October, so you get about six months a year of deposits going on and six months of them sitting there curing. A droplet lands, the Idaho sun evaporates the water, and the mineral stays behind concentrated into a ring. Repeat that three times a week for a decade and it stops being a spot you can wipe. Homes on culinary water alone don't do this. That is why hard water damage in this subdivision tracks the sprinkler layout almost perfectly, house by house.
BanBury and BanBury Meadows have two separate irrigation problems and they hit different sides of the house. The common landscaping — entry monuments, street frontage, the turf strips along the course — runs on commercial-grade rotors that cycle at night at higher pressure and longer run times than anything in your back yard, and nobody is standing there watching where the arc ends. Homes backing or siding onto those strips take mineral on the street-facing and course-facing elevations, high up, because a rotor throws far. Your own zones are a different pattern: fixed spray heads on the lawn panels, closer to the wall, hitting the bottom four feet of the glass and the sidelights by the front door. The two look different once you know what you're looking at.
South and west glass is always the worst in BanBury, and it isn't because those heads run more. It's evaporation. A droplet on a west-facing pane at four in the afternoon in July flashes off in under a minute, so the mineral has no chance to run down and off — it dries in place, right where it landed, and bakes. The same water on a shaded north elevation stays liquid long enough to sheet off, and what's left is softer and lifts easier. So on a typical BanBury house we'll find heavy bonded deposit on the west great-room wall and the south sidelights, moderate on the east, and light on the north. Two houses a block apart can be completely different depending on head placement and which way the great room faces.
Here is the honest part, and you can do it yourself before you ever call us. Wet the stained glass down with a hose. If the haze disappears while the pane is wet and comes back as it dries, the mineral is sitting on top of the glass and it will come off. If the cloudiness is still visible while the glass is soaking wet, the mineral has bitten into the silica and you are looking at etching, not deposit. Etched glass does not come back with any chemical, pad, or pressure — restoration polishing can improve it, and past a certain depth the only real fix is replacement. We test a corner and show you before we quote. Nobody should pay to have permanent damage scrubbed at.
Removing stains without changing what caused them just buys you two seasons. When we're on site we'll show you which head is doing it — usually one misaligned spray after somebody bumped it mowing, or a rotor arc set past the lawn edge. A sprinkler tech can re-aim it in ten minutes. Best timing is late October, right after the irrigation district shuts water off, so the glass goes into winter clean; second-best is April before the first cycle. Pricing is quoted by severity, because light surface scale and ten-year bonded deposit are not the same job. Stain treatment is included on the Monthly membership, no contract either way, and every visit carries our 7-Day Rain Guarantee. Same-day and next-day slots. Call (208) 453-6760.

Head placement and sun exposure. If your spray heads sit farther off the foundation and your great room faces north, droplets sheet off before they dry and you get almost nothing. Your neighbor may have a rotor from the HOA common strip throwing onto a west wall that bakes every afternoon. In BanBury the pattern follows the sprinklers, not the age or size of the house.
No, and pressure is the wrong tool entirely. Mineral scale is chemically bonded to the glass surface — force doesn't break that bond, it just risks driving water past the seals on clad-wood frames and blasting the screen frames. Stain removal is a chemical and abrasive-pad process done by hand, pane by pane. If someone quotes you a pressure wash to fix window stains, that's a red flag.
Document it before you go to the board. Take photos of the elevation and, if you can, get out early enough to watch the common zone run and see where the arc actually lands. Boards respond to a specific head and a specific overthrow, not to a general complaint. We can tell you which elevation the mineral pattern points back to when we're on site.
Not once it's bonded. Standard cleaning with pure deionized water removes dirt, pollen, and fresh water spots, and it will not leave anything behind — but it doesn't dissolve mineral that's already cured onto the glass. That's a separate restoration process and it's quoted separately by severity. Fresh spots from this season usually do come off in a normal clean; multi-year buildup won't.
Late October is ideal — the irrigation district has shut the water off, nothing new is landing on the glass, and your windows stay clean through winter. April, before the first cycle, is the next best. Doing it in July means you're fighting the sprinklers the same week you paid to fix them, unless the heads have already been re-aimed.
It's quoted by severity rather than flat-rated, because a season of light spotting and a decade of bonded scale are different amounts of labor. We look at the actual glass first.
