Ashton Hills sits in Caldwell off Cleveland Blvd in 83607, and it is a turn-of-the-2000s subdivision, recorded 1999–2003 across 5 phases. At roughly 66 acres and about 285 lots it is a mid-sized pocket. What shows up on the glass here is untreated surface water through the city's own irrigation district: every sprinkler cycle that reaches a window leaves silt and dissolved mineral behind to dry in place.

The mineral on Ashton Hills glass does not come from the sky. It comes from the Caldwell Municipal Irrigation District, with storage held by Pioneer Irrigation District, which delivers untreated surface water to the sprinklers on a separate line, and it is compounded by Caldwell's groundwater supply, which is hard enough that most households here see scale on fixtures long before they notice it on glass. Every irrigation cycle that reaches a window deposits a little silt and a little dissolved mineral, and every evaporation concentrates what is already there. Over a season it bonds; past that it begins to etch the glass itself. This is why an ordinary wash looks fine on the day and hazy again within weeks — the deposit was never removed, only wetted. Deionized water dissolves it rather than redistributing it.
Two decades of sprinkler cycles have left most Ashton Hills panes with a mineral history rather than mineral dirt, and only one of those comes off. A deposit that has bonded but not yet etched responds to a dedicated dissolver and mechanical work; glass that has etched has lost surface and no product restores it. We check before quoting rather than after, and where a pane is gone we say so.
Caldwell is one of the few cities in the valley that runs its own irrigation district — the Caldwell Municipal Irrigation District delivers untreated surface water to yards across town, and a lot of the older grid is still on gravity rather than pressure. What reaches the glass is canal water either way. Caldwell is really two cleaning problems wearing one city's name. The old grid around Indian Creek and downtown is pre-war and early-post-war housing: original wood sashes in places, single-pane and storm windows, mature trees dropping sap and tannin, and gravity irrigation running in ditches rather than pressurised pipe. The newer subdivisions on the south and west edges are production builds from the last twenty years with big rear glass packages, tight lots and pressurised sprinklers throwing canal water directly onto the windows. The same company should be able to do both, but not with the same method — one is careful hand work around failing glazing putty, the other is pole work and mineral removal. We will tell you which one your house is.
There is no single right interval and anyone quoting one without seeing the property is guessing. What drives it here is sprinkler exposure more than anything else. We will tell you what we think after the first visit, and it is frequently less often than people assume.
Cleaning without changing the cause buys one season. On a Ashton Hills lot it is almost never every head that is the problem — it is two or three throwing onto glass, and a quarter turn on each does more for the next six months than the cleaning itself. We point them out while we are there. It costs you nothing and it is the single highest-value thing anyone can tell you about windows in this valley.
Exterior window cleaning starts at $199 and is priced by pane count rather than square footage, because panes are what take time. Interior is quoted the same way. Screens are a $50 add-on alongside a window service. Gutters start at $199. House washing is $0.18 a square foot, pressure washing $0.20. Hard water restoration is quoted per affected pane after we test one. No contract.

The irrigation water, nearly every time — the Caldwell Municipal Irrigation District, with storage held by Pioneer Irrigation District delivers untreated surface water to the sprinklers, and it carries silt and dissolved mineral that treated water does not. Any head throwing onto a pane leaves both behind every cycle. The fix is part cleaning and part aim: we will show you which heads are hitting glass.

Hold a wet finger against it. If the haze disappears where it is wet and returns as it dries, it is deposit and it can come off. If it stays visible while wet, the mineral has etched into the silica and cleaning will not remove it. We test a single pane before quoting so you are not paying to find out.
Wherever the elevation allows, yes. Carbon-fiber water-fed poles reach most second-story glass from the ground, which keeps ladder feet off landscaping and off the roof. Where a pole will not do a clean job we ladder it properly. We do not do rope-access or high-rise work.
