The best months for composite deck in Buffalo
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Buffalo (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Buffalo 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.
Buffalo gets about 41 inches of precipitation in a normal year, including roughly 95 inches of snow. The wettest months are September, October and December (4.1 inches in September). Inside the workable window, July and August are the driest, at 3.2 and 3.2 inches. The station averages about 3 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: Buffalo trade wages
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 Buffalo the blend is 1.05.
Carpenters (47-2031), 80% of the weighting: a median of $30.53 an hour, 5% above the US median of $29.12. The middle half of them earn between $24.07 and $35.88 an hour. About 2,440 work in the metro. That is 45.6 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 $24.34 an hour, which is 7% above the national $22.66. The middle half of them earn between $21.72 and $32.68 an hour. BLS counts 2,790 of them working in the area, 52.2 for every 10,000 jobs (US: 70.5), so the local bench is thinner than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,600 to the midpoint estimate; the 25th percentile takes off about $1,900. That is a swing of roughly 10.3% to 8.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Buffalo-Cheektowaga has 534,550 jobs in total (BLS, May 2025), ranking 49th by size among the 300 metros on this site.
