Two Waterfront District buildings a block apart can have completely different glass. One has clear windows and one has a milky band across every ground-floor pane, and the difference is almost never the homeowner. It is whose sprinklers water that strip, when they were installed, and which way the heads got aimed.
The Waterfront District went in after about 2005, which means the sprinklers went in with the buildings rather than getting added on over forty years like they did on the older Garden City ranches south of Chinden. On a 1960s block, every yard has a different system from a different decade, so the damage is scattered. Here the common strips along Whitewater Park Blvd and the greenbelt side were laid out by one contractor on one plan, and a lot of it is on surface water shares delivered through the ditch rather than off the house hose bib. That means the same rotor heads throw the same silty water at the same buildings on the same HOA schedule, several cycles a week, all season. When we walk a Waterfront District job we can usually predict which units are bad before we get out of the truck.
This matters because it decides whether the stain will come back. If the damage is coming from a head in your own bed, you can turn it down or swap a nozzle the same afternoon and the restoration holds for years. If it is coming from an HOA common strip, you do not own that valve, and a head that was aimed at a shrub bed in 2007 has been drifting onto the same glass ever since. Rotor heads on shared strips also run at higher pressure and throw farther than a residential spray head, so they reach second-floor glass that a homeowner system never would. We will tell you which one you have and, if it is the HOA's, put it in writing so you have something to hand the management company.
It is not random. The worst glass in this neighborhood is ground-floor and low second-floor panes on the side facing a common landscape strip or a shared walkway, usually within about twenty feet of a rotor head. West and southwest elevations along the greenbelt side are worse than the rest because afternoon sun bakes the droplets dry before they can run off, and heat is what turns a rinse-off deposit into bonded scale. Third-floor picture windows and rooftop deck glass are almost always clean, since nothing sprays that high. Windward corners catch drift on windy evenings even when the head is not pointed at them. If you have a milky band that stops at a consistent height across several panes, that is the top of the spray arc, and it is diagnostic.
Ditch water pulled off the river carries silt, and silt sits on top of the glass. That comes off with a normal wash, and if that is all you have, do not pay for restoration. Underneath it is the mineral, calcium and magnesium left behind when the droplet evaporates. Early on it sits on the surface and lifts with a mild acidic treatment. Left through several seasons it bonds and then bites into the glass surface itself, and at that point it is etching, not a stain. Here is the honest part. Etched glass has to be polished with a cerium compound by hand, panel by panel, and on deep cases we can get it eighty or ninety percent back but not to new. Anyone promising you perfect glass on a fifteen-year deposit has not looked at it closely.
Hard water work is quoted by severity, not by pane count, because a light seasonal film and a decade of bonded scale are not the same labor. We look at the actual glass first and give you a number before anything starts. It is included on the Monthly membership. Memberships run Monthly or Quarterly with no contract, and there is a 7-Day Rain Guarantee. After restoration we clean the glass with 100 percent pure deionized water, which carries no dissolved minerals of its own and dries without leaving anything behind. But restoration only holds if the head gets fixed. We will show you the one throwing on your windows before we leave.

Almost always sprinkler aim and distance, not anything you did. A rotor head on a common strip twenty feet from your wall will hammer your glass every cycle while a unit forty feet down the row gets nothing. Add a west-facing wall that bakes the droplets dry in the afternoon and you get bonded scale on one building and clean glass on the next.
Yes, though not overnight. On a head that hits your glass several cycles a week you will see visible film again within a season or two. If you cannot get the head redirected, a Monthly membership is the practical answer, because catching the deposit while it is still soft is far cheaper than polishing etched glass later. We will document which head is doing it so you have something to send the management company.
We check on site. A fingernail or a wet rag on one pane tells us most of it. If it wipes with water it is silt and you only need a wash. If it resists but lifts with a mild acidic treatment, restoration will work. If it stays after that and you can feel texture in the glass, it is etched and we will tell you what percentage we honestly expect to recover before you commit.
No. Window cleaning is deionized water on a pole, no soap, and it removes dirt and light film. Hard water restoration is a separate hand process using acidic or polishing compounds worked pane by pane, and it takes considerably longer per window. We finish with a deionized rinse, but the restoration itself is its own service and gets quoted separately by severity.
Usually not. Sprinklers do not reach that high, so the upper floors and rooftop deck glass in this neighborhood are typically clean of mineral damage even when the ground floor is bad. What upper glass does collect is general grime and cottonwood residue, which comes off with a standard deionized clean. We would rather quote you honestly on the six panes that need work than the whole building.
On fresh deposits from this season, sometimes. Vinegar and a non-scratch pad will lift a light film off a ground-floor pane. It will not touch anything bonded, and on tempered glass or a coated pane the wrong pad leaves scratches that are permanent and more visible than the stain was. If a first pass with vinegar does not obviously improve it, stop before you damage the surface.
