Glass that disappears.

What’s included

• Exterior glass, hand-washed or pure-water fed pole
• Interior glass where access is arranged
• Screens removed, washed and reinstalled
• Sills and tracks vacuumed and wiped
• Frames wiped down
• Hard-water and mineral spot treatment (quoted separately)
• Cobweb removal around frames and eaves
• Drop cloths and shoe covers inside

How we do it

1. We walk the property firstCount panes, note which ones are second-story, fixed, or over a roofline, and flag any glass with mineral etching that a normal wash will not touch.
2. Screens and tracks come firstScreens come out and get washed separately. Tracks get vacuumed before any water goes near them, so grit does not turn into mud in the channel.
3. Wash, then pure-water rinseGround-floor and reachable glass is hand-washed with a squeegee. Upper glass is done with a water-fed pole and deionized water.
4. We check it from outside and inLow-angle light shows what straight-on light hides. We look at every pane from both sides before packing up, and walk it with you if you are home.

Why glass gets dirty faster here

Three things work against windows in the Gallatin Valley, and they are not the same three that a window cleaner in Seattle deals with.

Hard water. Valley water carries a lot of dissolved mineral. Every time a sprinkler head throws spray onto a south- or west-facing window and the sun bakes it off, it leaves the mineral behind. Do that for three summers and you get a cloudy haze that soap will not remove — it has to be treated, and past a certain point the glass is permanently etched.

Wind and grit. The valley moves a lot of dust, and in spring it moves whatever was spread on the roads all winter. That fine grit ends up in the bottom track of every window, where it holds moisture against the frame.

Smoke. Late-summer smoke settles a fine oily film on glass that is noticeably harder to cut than dust. A wash right after the air clears makes more difference than one in mid-August.

What drives the price

We quote every property individually rather than publishing a flat rate, because these six things change the number more than anything else. Nothing on your invoice will differ from the written quote.

• Pane countThe main driver. We count openings, not panels — a big fixed picture window is one, a six-over-six is one.
• Stories & accessSecond- and third-story glass, and anything over a roofline or a steep grade, takes longer and needs different equipment.
• Inside & out, or exterior onlyExterior-only runs meaningfully less and needs nobody home.
• ConditionGlass washed last season cleans fast. Glass that has not been done in five years, or has sprinkler mineral on it, is a different job.
• Screens & tracksIncluded in a standard wash. Heavy buildup in the tracks may add time.
• FrequencyTwice a year keeps each visit shorter and cheaper than one annual catch-up.
