Data note: 10% of the labor weighting for this project uses a statewide median because BLS has no published metro figure for that trade in Flint. The wage table below marks each row.

The best months for home addition in Flint
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Flint Bishop Intl 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 Flint are April through October: 7 of 12. Outside them, January, February, March, November and December have an average overnight low at or below freezing (32°F).
In January, February, March, November 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 141 days a year with a low at or below 32°F at this station.
Flint gets about 32 inches of precipitation in a normal year, including roughly 52 inches of snow. The wettest months are May, July and August (3.7 inches in May). Inside the workable window, September and October are the driest, at 2.9 and 2.8 inches. The station averages about 11 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.

Who does the work: Flint trade wages
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 Flint the blend is 1.09.
Carpenters (47-2031), 50% of the weighting: a median of $29.50 an hour, in line with the US median of $29.12. The middle half of them earn between $23.41 and $33.59 an hour. About 330 work in the metro. That is 24.4 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $28.85 an hour, 5% above the US median of $27.41. The middle half of them earn between $22.86 and $30.28 an hour. About 400 work in the metro. That is 29.6 per 10,000 jobs, compared with 13.3 nationally, which suggests plenty of local crews to bid.
For electricians (47-2111, weighted 10%) the local median is $37.63 an hour, which is 24% above the national $30.38. The middle half of them earn between $28.37 and $44.38 an hour. BLS counts 790 of them working in the area, 58.5 for every 10,000 jobs (US: 48.7), so the local bench is deeper than average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $38.71 an hour, 26% above the US median of $30.67. The middle half of them earn between $28.11 and $47.94 an hour. About 790 work in the metro. That is 58.5 per 10,000 jobs, compared with 30.0 nationally, which suggests plenty of local crews to bid.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for the Flint metro, so we used the Michigan statewide median: $28.10 an hour against $28.33 for the US. The middle half of them earn between $22.82 and $34.00 an hour.
Roofers (47-2181), 10% of the weighting: a median of $34.02 an hour, 28% above the US median of $26.65. The middle half of them earn between $22.00 and $34.02 an hour. About 120 work in the metro. That is 8.9 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 $2,700 to the midpoint estimate; the 25th percentile takes off about $4,000. That is a swing of roughly 6.7% to 4.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Flint has 135,040 jobs in total (BLS, May 2025), ranking 163rd by size among the 300 metros on this site.
