Saginaw weather and the composite deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Saginaw #3 (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 Saginaw are April through November: 8 of 12. Outside them, January, February, March and December have an average daytime high under 45°F.
In January, February, March 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.
Saginaw gets about 34 inches of precipitation in a normal year, including roughly 41 inches of snow. The wettest months are April, May and August (3.6 inches in April). Inside the workable window, September and November are the driest, at 2.7 and 2.6 inches. The station averages about 13 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 Saginaw
The labor line is built from BLS wage data, one trade at a time. This job draws on 2 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 Saginaw the blend is 1.03.
Carpenters (47-2031), 80% of the weighting: a median of $29.92 an hour, in line with the US median of $29.12. The middle half of them earn between $23.74 and $33.72 an hour. About 320 work in the metro. That is 40.0 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $23.56 an hour, which is 4% above the national $22.66. The middle half of them earn between $18.16 and $28.62 an hour. BLS counts 540 of them working in the area, 67.5 for every 10,000 jobs (US: 70.5), 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 $1,150 to the midpoint estimate; the 25th percentile takes off about $1,850. That is a swing of roughly 10.2% to 6.3% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Saginaw has 80,000 jobs in total (BLS, May 2025), ranking 239th by size among the 300 metros on this site.

Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).
Labor
