Most houses within walking distance of College of Idaho were built before automatic sprinklers existed. The systems got retrofitted later, one owner at a time, with no HOA setting a standard - so on Blaine, Filmore and Hays, etching severity changes house to house instead of block to block.
Newer Caldwell subdivisions were platted with irrigation designed in - one contractor, one head layout, HOA common turf running on a shared timer. The blocks around College of Idaho got none of that. These houses predate automatic sprinklers by decades, so systems went in later and individually, whenever a given owner decided to stop dragging a hose. Some are old brass impact heads on galvanized line. Some are landlord-installed rotors aimed at whatever was cheapest to trench. There is no HOA landscape crew adjusting anything, and on a rental lot nobody notices the head a mower knocked sideways two seasons ago. That is why we can quote heavy etching on one house and light spotting next door - same street, same water, completely different spray pattern hitting the glass.
Lots near campus are narrow, and the house usually sits close to the front setback with the strip between sidewalk and curb still getting watered. That puts heads within throw distance of the front elevation, so street-facing ground-floor windows almost always show the worst deposits. After that it is whichever wall gets afternoon sun - west and southwest glass, because overspray dries on the pane before it can run off and leaves the mineral sitting there instead of carrying it down. North-side windows on the same house are often fine. When we walk a bid here we start on the street side, then the west wall, and we frequently find the back of the house needs nothing at all. You should not be paying to restore glass that is not etched.
Caldwell sits in Pioneer Irrigation District territory, and whether your sprinklers pull from an irrigation share or off the city tap changes what ends up on the glass. Untreated ditch water carries silt along with the minerals and leaves a gray, slightly gritty film that hazes the whole lower pane. Treated city water goes on clear, so it dries into harder, brighter white spotting and rings, usually concentrated in the arc where a head sweeps. Older campus-area lots are a mix - some kept an irrigation share from when this ground was farmed, others got switched to hose bibs on domestic water a long time ago. Tell us which you have, or we will read it off the deposit when we look.
Hard water sits on glass in stages. Fresh deposits come off with an acidic compound and a rinse. Deposits that have baked through a few Caldwell summers need a mild abrasive polish worked by hand. But if a sprinkler has been hitting the same pane for ten or fifteen years, the mineral has pitted into the surface of the glass itself, and no compound puts silica back. On those we can usually take a window from cloudy to clearly better, and we will tell you before we start that it will not look like new glass and that replacement is the only true fix. Pressure washing does nothing for any of it - pressure moves dirt, not bonded mineral. Anyone quoting a pressure wash for hard water stains has not done this work.
We quote hard water stain removal by severity rather than pane count, because light spotting and a fifteen-year etch are wildly different amounts of labor on the exact same window. On the Monthly membership it is included. Either way, restoration is wasted money if the head that caused it is still aimed at the house. Before we come out, run your zones and watch where the water actually lands - a five-degree turn on one head, or swapping a full-circle nozzle for a half, is usually the entire fix. We will point out the offenders while we are there. Reflekt was started in 2025 by Hunter Stevens and Ethan Seusy, is locally owned and fully insured, and holds 4.9 stars across 115+ Google reviews.

Usually we get most of it. If the deposit is sitting on top of the glass, an acidic compound and a hand polish will clear it. If a head has been hitting that pane for a decade or more, the mineral has etched into the surface and no product restores it completely. We test the worst window first and tell you honestly which one you have before you commit to the job.
Because irrigation around campus was retrofitted house by house. There is no HOA system and no shared design, so one lot has heads angled down into the turf and the next has a rotor throwing straight at the siding. Age matters too - an old impact head that has drifted a few degrees since it was installed will chew up one elevation and leave the rest of the house clean.
Before, if you can. Restoring glass and then soaking it again the following week means paying twice. Run each zone for a minute and watch where the spray actually lands on the house, not just where the lawn gets wet. Most of the time it is one or two heads. If you cannot get to it, we will still do the work and flag which heads are causing it while we are on site.
No. Pressure moves loose dirt, and hard water mineral is bonded to the surface. Blasting a window with pressure risks the seal and the frame and still leaves the stain. Concrete is the same story - sprinkler mineral on a driveway or walkway needs the right cleaner to break it down first, and pressure alone just cleans around it and makes the stained arc look sharper.
It is included on the Monthly membership. Otherwise we quote it by severity after looking at the glass, because light spotting and a badly etched west-facing window are very different amounts of hand work. Memberships have no contract, and the 7-Day Rain Guarantee covers the regular window cleaning side of the visit.
Yes. A lot of the housing around College of Idaho is rented, and mineral etching on a ground-floor window is one of the first things a prospective tenant or buyer notices. We work with property managers and owners directly, can take a same-day or next-day slot during a turnover, and send photos when it is finished. Just tell us how you want it billed.
