Nicol-farwell sits in Caldwell just off S Georgia Ave, a short run from Cleveland Blvd in 83605, and it is older than most of the city around it — recorded 1961 on one plat. At roughly 41 acres and about 35 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.

Two separate water supplies reach a Caldwell window and both of them are hard. The first is Caldwell's groundwater supply, which is hard enough that most households here see scale on fixtures long before they notice it on glass. The second, and the one that actually does the damage, is the Caldwell Municipal Irrigation District, with storage held by Pioneer Irrigation District — untreated surface water delivered to the sprinklers, carrying suspended silt and dissolved calcium and magnesium straight off the canal. When a head clips a pane the water sheets, evaporates fast in the valley's dry air, and leaves the silt as a gritty film and the mineral as a bonded ring. Soap moves the first around and does nothing to the second. We run 100% deionized water instead — stripped of its own minerals, it pulls the deposit into solution and dries leaving nothing behind to catch the next round.
Nicol-farwell predates most of the city around it, and the glass reflects that. Homes of this era often still carry single-pane units, wood or early aluminum frames, and in some cases the original float glass, which is softer and scratches more readily than anything made recently. Some still have storms over the primaries. None of that is a problem — it makes this hand work rather than production work. No blade on old glass without testing a corner, and no water forced into failing wood putty.
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.
Most of what makes a window look bad is not the glass. Silt runs off the pane into the bottom track and compacts; the exterior sill collects the same material plus whatever the wind brings; and the screen in front is a filter that has been filtering all season. Clean the glass alone and the window still looks wrong. We detail track and sill as part of the service, and we stay off the seal line with anything high-pressure or metal.
Cleaning without changing the cause buys one season. On a Nicol-farwell 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.
A screen is a filter and it has been doing its job all summer. Silt dries in the weave and greys the whole view, so a perfectly clean pane behind a loaded screen still looks dirty. We would rather you added screens to the booking than paid for a window clean and felt it had not worked.

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.

Exterior window cleaning starts at $199, 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. Hard water stain removal is quoted per affected pane after we test one. No contract.
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.
