Where the St. Louis price comes from
Labor is 30% 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 St. Louis the blended ratio comes out at 1.12.
Materials are scaled with BEA's regional price parity for goods. St. Louis is at 100.0 against 100 for the US, so a materials line of $7,100 nationally becomes $7,100 here (midpoint, 10 windows). Permits follow the all-items index of 95.1: $0 to $0.
Who does the work: St. Louis trade wages
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 St. Louis the blend is 1.12.
Glaziers (47-2121), 50% of the weighting: a median of $29.51 an hour, 8% above the US median of $27.44. The middle half of them earn between $22.97 and $38.94 an hour. About 230 work in the metro. That is 1.7 per 10,000 jobs, compared with 3.8 nationally, so expect fewer local crews to bid.
Carpenters (47-2031), 40% of the weighting: a median of $34.13 an hour, 17% above the US median of $29.12. The middle half of them earn between $25.32 and $44.28 an hour. About 7,210 work in the metro. That is 53.8 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For general maintenance and repair workers (49-9071, weighted 10%) the local median is $25.93 an hour, which is 9% above the national $23.84. The middle half of them earn between $21.35 and $31.49 an hour. BLS counts 13,170 of them working in the area, 98.2 for every 10,000 jobs (US: 98.4), so the local bench is about average.
A quick sensitivity check: moving the lead trade (glaziers) from the median to the 75th percentile wage adds about $460 to the midpoint estimate; the 25th percentile takes off about $320. That is a swing of roughly 3.2% to 4.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
St. Louis has 1,341,320 jobs in total (BLS, May 2025), ranking 23rd by size among the 300 metros on this site.

The best months for windows in St. Louis
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, St Louis Sci Ctr (in the city). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in St. Louis are February through June and August through December: 10 of 12. Outside them, January has an average daytime high under 45°F, and July has an average daytime high of 90°F or more.
In January 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.
St. Louis gets about 44 inches of precipitation in a normal year. The wettest months are April, May and June (4.9 inches in May). Inside the workable window, February and December are the driest, at 2.3 and 2.6 inches. The station averages about 47 days a year at 90°F or above.
We do not adjust the estimate by month, because we have no reliable published data on seasonal pricing. It is still worth asking contractors whether an off-peak start date changes their bid.
