East End has no HOA and no common landscaping, so every sprinkler system here is a one-off retrofit somebody added decades after the house was built. Two 1920s bungalows on the same block can have completely different etching, because one owner aimed his heads at the lawn and the other aimed them at the siding.
In the newer subdivisions west of here, one landscape contractor installed every system in the neighborhood the same year, aimed them the same way, and an HOA still waters the common strips on one clock. Whole streets share the same stain pattern. East End is the opposite. These houses went up between roughly 1905 and 1935, decades before anyone put in an underground system, so what's in the ground now is whatever each owner added in the 1970s, or the 1990s, or last spring. Heads get moved when a bed changes and never re-aimed. That's why we quote this service house by house here instead of by block. We've walked two Craftsmans four doors apart where one had clean glass all around and the other had a hard mineral arc burned across every window on the south side.
Some East End lots still hold gravity irrigation shares off the old canal system and water the lawn with ditch water. Many don't and run straight off city pressure. It matters, because the two deposits behave differently on glass. Ditch water carries silt and organic fines along with the minerals, so it dries to a gritty gray-tan film that washes off easier than it looks but comes back fast and scratches if someone dry-wipes it. City water is cleaner going on and worse long term: it's straight dissolved calcium and magnesium, it dries clear, and the homeowner often doesn't notice until it's already bitten into the glass. If you're on the ditch, we clean it and it usually looks new. If you're on city pressure and it's been ten summers, that's a different conversation.
These are deep, narrow lots with the house pushed toward the street and an alley out back. The side yards are often eight to twelve feet wide, which means a rotor or a mid-range spray head set in that strip cannot water it without also watering the house. So the damage here concentrates on side elevations, on the low basement and daylight windows that sit closest to head height, and on porch and bay glass at the front where a lawn head overthrows the walk. Back elevations on the bigger Greenbelt-side lots take it too, from rotors reaching across a long back lawn. Street-facing upper sash usually stays clean, which is the tell: if your uppers are fine and your lowers are hazed, that's sprinklers, not weather.
Stage one is surface deposit sitting on top of the glass. It comes off with deionized water and hand work and the window looks new. Stage two has started to bond and takes a mineral treatment and dwell time, still fully recoverable. Stage three is etching: the minerals have eaten into the glass and there's nothing left to remove. Here's the field test, and you can do it yourself. Wet the pane and look at it wet. If the cloudiness disappears under water and returns as it dries, it's stage one or two and we can fix it. If you can still see the sprinkler arc while the glass is soaking wet, it's in the glass. On modern float glass, polishing is sometimes an option. On East End's original wavy cylinder glass we won't do it, because polishing removes material and takes the ripple and the character with it. We'll tell you that up front rather than take the job.
Hard water stain removal is quoted by severity, not by pane count, because a light seasonal film and eight years of bonded scale are not the same labor. We look at it, tell you which stage you're at, and give you a real number. On a Monthly membership it's included, which is how most East End customers handle it once we've reset the glass, since the cheapest version of this problem is never letting it rebuild. We'll also flag the head that's causing it while we're there. Half the time the fix is a two-dollar nozzle swap or turning an arc twenty degrees off the house, and that's not something we charge for.

Because in East End there's no HOA and no shared system. Your sprinklers and theirs were installed by different people in different decades and aimed differently. One head throwing across an eight-foot side yard into the house will etch that elevation for years while the identical bungalow next door, whose heads sit lower and closer to the lawn, never gets a mark. It's an aiming problem more than a water problem.
Wet the window with a hose and look at it soaking wet. If the haze vanishes while it's wet and reappears as it dries, the mineral is sitting on the surface and we can take it off. If you can still see the spray pattern on wet glass, the minerals have etched into the surface and there's nothing left to remove. We check this on every pane before quoting, and we'll tell you which windows are recoverable and which aren't.
Yes, with limits. Deposit and bonded scale come off with deionized water, hand work and a mineral treatment, no razor blades and no flooding old glazing putty lines. What we won't do on original cylinder glass is aggressive polishing, which is how etching gets addressed on modern float glass. Polishing removes material and flattens the ripple that makes that glass worth keeping. If a pane is etched, we say so instead.
It changes what we're dealing with. Ditch water leaves a gritty gray film with silt in it that looks bad but usually cleans off well, though it will scratch if it's dry-wiped. City water dries clear and bonds harder, so people miss it until it's etched. Either way we treat the glass the same way, but ditch-water houses tend to grade lighter than they look and city-pressure houses tend to grade worse.
They will if the head that caused them is still pointed at the house. Removing the stain resets the glass, it doesn't change the water. That's why we look at the sprinklers while we're there and tell you which one is doing it, and why most East End customers put the property on a Monthly membership afterward, where this is included and the film never gets a chance to bond again.
Common here, since a lot of East End homes still run seasonal storms over original sash. Water gets behind the storm, sits, and dries with no airflow, which is a good way to build scale on both surfaces. We can pull storms to reach the glass, and we'll mention it if the storm frame's weep holes are plugged, because that's usually the reason water is sitting in there to begin with.
