Window replacement: what moves the price in Montana
Frame material
Vinyl windows run $350-$1,500 each installed, fiberglass $400-$2,000, composite $400-$2,300, and wood $800-$3,800 (HomeGuide).
Window type
Single-hung and picture windows are cheapest; bay and bow windows can reach $3,000-$8,000+.
Count
Replacing 10 to 15 windows runs $4,500-$22,500; at 25 windows it is $11,250-$37,500.
Permit
Window permits are $50-$200 each, or $400-$600 total for a multi-window job, and are often only needed when you change the opening (HomeGuide). No permit fee is included here because many cities do not ask for one on same-size replacements.
If you are planning more than one job in Montana
The table prices neighboring jobs at their usual sizes using statewide Montana wages and prices. Against national midpoints, vinyl siding comes out highest (−2%) and patio door lowest (−5%), because each job leans on different trades.
| Project | Size | Range | vs. US |
|---|---|---|---|
| Patio door | 1 door | $570 – $5,700 | −5% |
| Front door | 1 door | $480 – $2,400 | −4% |
| Storm door | 1 door | $340 – $910 | −4% |
| Vinyl siding | 2,100 sq ft of wall | $8,250 – $24,700 | −2% |
| Garage door | 1 door | $690 – $3,600 | −2% |
Montana metro-by-metro prices
1 of the 3 metros sit above the statewide midpoint of $9,250, and the top-to-bottom gap is 1%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (10 windows) | Midpoint | vs. state |
|---|---|---|---|
| Bozeman, MT | $4,300 – $14,300 | $9,300 | +1% |
| Billings, MT | $4,250 – $14,300 | $9,250 | level |
| Missoula, MT | $4,250 – $14,200 | $9,250 | level |

Weather windows across Montana
Season matters for windows. For each Montana metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Billings has the longest comfortable season of the metros we cover in Montana at 9 months (March through November); Missoula has the shortest at 8 (March through October). Rainfall runs from 14 inches a year in Missoula to 20 inches in Bozeman.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Billings | 18 | 87 | 14 | 9: March through November |
| Bozeman | 15 | 82 | 20 | 8: March through October |
| Missoula | 18 | 85 | 14 | 8: March through October |
Wages behind the Montana number
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 3 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.92 for Montana.
For glaziers (47-2121, weighted 50%) the local median is $23.73 an hour, which is 14% below the national $27.44. The middle half of them earn between $22.14 and $29.04 an hour. BLS counts 410 of them working in the state, 8.0 for every 10,000 jobs (US: 3.8), so the local bench is deeper than average.
For carpenters (47-2031, weighted 40%) the local median is $28.28 an hour, which is in line with the national $29.12. The middle half of them earn between $23.84 and $32.47 an hour. BLS counts 4,030 of them working in the state, 78.8 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
General maintenance and repair workers (49-9071), 10% of the weighting: a median of $22.54 an hour, 5% below the US median of $23.84. The middle half of them earn between $18.50 and $28.02 an hour. About 5,420 work in the state. That is 105.9 per 10,000 jobs, compared with 98.4 nationally, so the supply of crews looks typical.
A crew paid at the 75th percentile for glaziers ($29.04 an hour) would add about $260 to the statewide midpoint; one at the 25th percentile ($22.14) would take off about $75. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 511,580 jobs across Montana (May 2025), which is 0.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Glaziers (47-2121) | 50% | $22.14 | $23.73 | $29.04 | $27.44 | 0.86 | state |
| Carpenters (47-2031) | 40% | $23.84 | $28.28 | $32.47 | $29.12 | 0.97 | state |
| General maintenance and repair workers (49-9071) | 10% | $18.50 | $22.54 | $28.02 | $23.84 | 0.95 | state |
