Why Janesville prices look the way they do
We price the labor side from BLS wage data for 3 trades: glaziers at 50%, carpenters at 40%, general maintenance and repair workers at 10%. Weighted together, Janesville wages are 1.16 times the national level. Labor makes up about 32% of the midpoint estimate (27% at national prices). BLS does not publish this trade for the metro, so we used the Wisconsin statewide median.
On the materials line, the BEA goods price index for the Janesville metro is 93.8 (US = 100). The midpoint materials bill for 10 windows comes to $6,650, compared with $7,100 at national prices. Permit and inspection fees are scaled by the broader index (93.7) 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 Janesville. The wage table below marks each row.

Janesville 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 Janesville is 1.16 times the national level.
Glaziers (47-2121) carry 50% of the labor weighting. BLS does not publish this trade for the Janesville metro, so we used the Wisconsin statewide median: $30.00 an hour against $27.44 for the US. The middle half of them earn between $24.52 and $44.10 an hour.
For carpenters (47-2031, weighted 40%) the local median is $36.24 an hour, which is 24% above the national $29.12. The middle half of them earn between $23.92 and $39.98 an hour. BLS counts 360 of them working in the area, 51.5 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 $27.21 an hour, 14% above the US median of $23.84. The middle half of them earn between $22.04 and $30.04 an hour. About 770 work in the metro. That is 110.2 per 10,000 jobs, compared with 98.4 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the glaziers on your job are paid at the 75th percentile ($44.10 an hour) instead of the median, the labor line grows by about $680. At the 25th percentile ($24.52) it shrinks by about $270. The total moves by 7.0% or 2.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 69,870 jobs in the Janesville-Beloit area. That makes it the 260th 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% | $24.52 | $30.00 | $44.10 | $27.44 | 1.09 | state |
| Carpenters (47-2031) | 40% | $23.92 | $36.24 | $39.98 | $29.12 | 1.24 | metro |

Climate in Janesville: timing your windows job
We use NOAA's 1991-2020 climate normals for Afton - Janesville Wwtp (5 miles from the city center). These are 30-year monthly averages, not forecasts.
March through November is the stretch where exterior installation runs into the fewest weather problems in Janesville (9 of 12 months). January, February and December have an average daytime high under 45°F.
In January, February 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.
Janesville gets about 37 inches of precipitation in a normal year, including roughly 37 inches of snow. The wettest months are June, July and August (5.0 inches in June). Inside the workable window, March and November are the driest, at 2.1 and 2.3 inches. The station averages about 13 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.
