What local crews earn in Janesville

The labor line is built from BLS wage data, one trade at a time. This job draws on 3 trades. We compare each trade's local median with the US median, weight the ratios by how much of the job each trade does, and apply the blend to the national labor cost. For Janesville the blend is 1.19.

Carpenters (47-2031), 60% of the weighting: a median of $36.24 an hour, 24% above the US median of $29.12. The middle half of them earn between $23.92 and $39.98 an hour. About 360 work in the metro. That is 51.5 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.

Glaziers (47-2121) carry 30% 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 general maintenance and repair workers (49-9071, weighted 10%) the local median is $27.21 an hour, which is 14% above the national $23.84. The middle half of them earn between $22.04 and $30.04 an hour. BLS counts 770 of them working in the area, 110.2 for every 10,000 jobs (US: 98.4), so the local bench is about average.

A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $120 to the midpoint estimate; the 25th percentile takes off about $410. That is a swing of roughly 11.6% to 3.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.

Janesville-Beloit has 69,870 jobs in total (BLS, May 2025), ranking 260th by size among the 300 metros on this site.
