Sprinkler etching in Hyde Park does not follow a subdivision pattern, because there is no subdivision. Every system between 13th and Fort went in on its own timeline, aimed at a yard that has since changed shape. Two bungalows on the same block of Alturas can have completely different glass.
In a subdivision built all at once, every house got the same sprinkler system from the same installer in the same year, so the etching pattern runs fairly uniform down the street and the HOA common landscaping sets a baseline. Hyde Park is the opposite. These lots were platted around 1900 and originally watered by hand or by gravity ditch, and the underground systems went in one house at a time. Some in the seventies, some last spring, some never. Nobody is running common landscaping to keep it consistent. That is why two bungalows on the same block of Eastman can have completely different glass: one has fixed spray heads tucked back into the beds and clean windows, the next has a rotor on a riser throwing water across the front porch every other morning since the eighties.
A lot of North End yards still carry irrigation water rights tied to the old canal laterals, and that season runs spring through early fall. If your system draws off that surface water, what lands on the glass is silty as well as mineral-bearing, and it hazes fast. You can usually feel a gritty film sitting on top of the spotting. City water off the tap runs cleaner but carries dissolved calcium, and that is what etches when it dries on hot glass. Plenty of houses here use both, ditch water while the lateral is running well and city water when pressure drops off or after the season closes. That mid-season switch is one reason the spotting on a single window can have two different textures stacked on it.
Overspray damage is not about how much water hits the glass. It is about how fast that water dries before it can run off. South and west elevations are where we find the real etching in Hyde Park, because a head cycling at six in the morning leaves a film that the sun bakes off by nine and leaves the mineral sitting there. North and east glass under the maple canopy usually just spots, since it stays wet long enough to sheet off. The other pattern is height. These lots run forty to fifty feet wide, so heads sit close to the foundation, and bungalow sills sit low to begin with. Basement and garden-level sash, front porch sidelights, and the bottom row of a divided-lite double-hung take nearly all of it. Upper sash is usually untouched.
Before you pay anybody to restore glass, do this yourself. Wet the spot with a spray bottle and look at it while it is still wet. If the mark disappears under the water and returns as it dries, the deposit is sitting on the surface and it will come off. If you can still see the outline while the glass is wet, the mineral has eaten into the surface. That is etching, not staining, and no chemical brings it all the way back. We tell you which one you have before we quote it. We also will not run an abrasive polish on original wavy glass in this neighborhood, because it takes the distortion out and the window stops looking like a 1912 window. Sometimes the honest answer is partial improvement, or replacement glass.
Hard water stain removal is quoted by severity rather than pane count, because a lightly spotted garden-level window and a south-facing sash that has been cooked for six seasons are nowhere near the same job. We look at the glass, run the wet test, and give you a number before anything starts. It is included on the Monthly membership, which is the sensible route if you have a head you cannot easily redirect and the film keeps coming back. Regular window cleaning starts at $199, and we work with 100% pure deionized water, so nothing we rinse with adds to the mineral load.

Because your sprinkler system and theirs were installed decades apart by different people, aimed at yards that have both changed since. A rotor head set in the eighties for a lawn that had a hedge along the walk is still throwing the same arc after the hedge came out, and now it hits the house. Nothing subdivision-wide evens that out in the North End. Severity here is per-house, sometimes per-elevation.
Spray the glass with water and look at the mark while it is wet. Surface deposits vanish under the water and reappear as it dries, and those come off. If the outline is still visible on wet glass, the mineral has etched into the surface and it is physical damage, not a film. We run that test in front of you and quote from what we see, not from a photo. If it is etched, we say so.
Yes, and we will tell you that rather than take the job twice. Restoring a south-facing window that gets hit every other morning buys you one season at best. Usually it is a five-minute fix: rotate the head, swap a rotor for a fixed spray, or drop a riser that got tall when the beds got mulched. Get that done, then restore. We are happy to point out which head is the culprit while we are there.
Surface deposits, yes. We can pull mineral film off old glass by hand without touching the glazing putty. Abrasive polishing is where we stop. Original glass in Hyde Park has waves and ripples in it that are part of why the house looks right, and a polish flattens that out permanently. On historic sash we would rather leave a faint mark than hand you back a window that looks like a modern replacement pane.
No. Pressure moves dirt, not minerals. Calcium bonded to glass is a chemical problem, and hitting it harder just risks the old glazing putty and the paint on the sash. Hard water work is done by hand with the right product and dwell time, then rinsed with deionized water so the rinse itself does not leave a new deposit. Anyone quoting you a pressure wash for stained glass is not going to fix it.
It is quoted by severity, because the range is wide. A garden-level window with one season of light spotting and a west-facing bungalow sash that has been sprayed for six years are different amounts of work. We look at it, run the wet test, and give you a real number first. It is included on the Monthly membership if you would rather keep it from building up. Call (208) 453-6760.
