What is behind the Flagstaff number
Labor is 27% of the midpoint bill here, against 27% nationally. The mix of trades behind this job is glaziers (50%), carpenters (40%), general maintenance and repair workers (10%). We weight each trade's local median wage by that share and compare it with the national median. In Flagstaff the blended ratio comes out at 0.96. BLS does not publish this trade for the metro, so we used the Arizona statewide median.
On the materials line, the BEA goods price index for the Flagstaff metro is 96.2 (US = 100). The midpoint materials bill for 10 windows comes to $6,800, compared with $7,100 at national prices. Permit and inspection fees are scaled by the broader index (100.3) and land at $0 to $0.
Data note: 50% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Flagstaff. The wage table below marks each row.
Climate in Flagstaff: timing your windows job
We use NOAA's 1991-2020 climate normals for Flagstaff Pulliam Ap (5 miles from the city center). These are 30-year monthly averages, not forecasts.
February through November is the stretch where exterior installation runs into the fewest weather problems in Flagstaff (10 of 12 months). January and December have an average daytime high under 45°F.
In January and December the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.
Flagstaff gets about 21 inches of precipitation in a normal year, including roughly 90 inches of snow. The wettest months are February, July and August (3.0 inches in August). Inside the workable window, May and June are the driest, at 0.8 and 0.3 inches. The station averages about 3 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Specs and site conditions that change a Flagstaff bid
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.
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+.

Flagstaff labor market for windows
Wages are the part of this estimate that changes most from town to town. 3 trades carry the job here, and each is compared with its US median. The weighted result for Flagstaff is 0.96 times the national level.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Flagstaff metro, so we used the Arizona statewide median: $27.19 an hour against $27.44 for the US. The middle half of them earn between $23.41 and $28.92 an hour.
For carpenters (47-2031, weighted 40%) the local median is $26.91 an hour, which is 8% below the national $29.12. The middle half of them earn between $22.77 and $30.14 an hour. BLS counts 280 of them working in the area, 42.0 for every 10,000 jobs (US: 43.1), so the local bench is about average.
General maintenance and repair workers (49-9071), 10% of the weighting: a median of $22.53 an hour, 5% below the US median of $23.84. The middle half of them earn between $18.65 and $27.06 an hour. About 1,090 work in the metro. That is 163.6 per 10,000 jobs, compared with 98.4 nationally, which suggests plenty of local crews to bid.
Quotes come from real crews, not medians. If the glaziers on your job are paid at the 75th percentile ($28.92 an hour) instead of the median, the labor line grows by about $85. At the 25th percentile ($23.41) it shrinks by about $180. The total moves by 0.9% or 2.0%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 66,610 jobs in the Flagstaff area. That makes it the 272nd largest of the 300 metros we cover, with 0.04% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Glaziers (47-2121) | 50% | $23.41 | $27.19 | $28.92 | $27.44 | 0.99 | state |
| Carpenters (47-2031) | 40% | $22.77 | $26.91 | $30.14 | $29.12 | 0.92 | metro |
