Peoria weather and the home addition calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Peoria Gtr Peoria Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For digging, grading and setting material in the ground, the comfortable months in Peoria are April through November: 8 of 12. Outside them, January, February, March and December have an average overnight low at or below freezing (32°F).
In January, February, March and December the average low is at or below freezing, which means frozen ground and slower digging, compaction and sod or stone placement. NOAA counts about 118 days a year with a low at or below 32°F at this station.
Peoria gets about 38 inches of precipitation in a normal year, including roughly 26 inches of snow. The wettest months are April, May and June (4.7 inches in May). Inside the workable window, October and November are the driest, at 3.2 and 2.7 inches. The station averages about 23 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.

What local crews earn in Peoria
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 Peoria the blend is 1.26.
Carpenters (47-2031), 50% of the weighting: a median of $36.19 an hour, 24% above the US median of $29.12. The middle half of them earn between $24.14 and $48.02 an hour. About 780 work in the metro. That is 47.0 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $34.94 an hour, 27% above the US median of $27.41. The middle half of them earn between $24.21 and $38.12 an hour. About 220 work in the metro. That is 13.3 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $38.68 an hour, which is 27% above the national $30.38. The middle half of them earn between $29.78 and $49.97 an hour. BLS counts 880 of them working in the area, 53.0 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $40.91 an hour, 33% above the US median of $30.67. The middle half of them earn between $29.63 and $51.67 an hour. About 560 work in the metro. That is 33.7 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Peoria metro, so we used the Illinois statewide median: $30.38 an hour against $28.33 for the US. The middle half of them earn between $24.78 and $49.27 an hour.
Roofers (47-2181), 10% of the weighting: a median of $36.83 an hour, 38% above the US median of $26.65. The middle half of them earn between $26.36 and $46.99 an hour. About 160 work in the metro. That is 9.6 per 10,000 jobs, compared with 8.7 nationally, so the supply of crews looks typical.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $7,750 to the midpoint estimate; the 25th percentile takes off about $7,900. That is a swing of roughly 12.0% to 11.8% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Peoria has 166,020 jobs in total (BLS, May 2025), ranking 141st by size among the 300 metros on this site.
