The best months for composite deck in Columbia
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Columbia U Of M (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 Columbia are February through November: 10 of 12. Outside them, January and December have an average daytime high under 45°F.
In January 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.
Columbia gets about 45 inches of precipitation in a normal year, including roughly 17 inches of snow. The wettest months are April, May and June (5.2 inches in May). Inside the workable window, February and November are the driest, at 2.3 and 3.0 inches. The station averages about 41 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.

Composite deck: what moves the price in Columbia
Engineering
Large or complex decks may need a structural engineer at $100-$220 an hour to get a permit.
Board grade
Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).
Labor
Labor for composite is $24-$48 per sq ft, higher than wood because the boards need extra parts and more careful assembly.
Who does the work: Columbia 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 Columbia the blend is 0.98.
Carpenters (47-2031), 80% of the weighting: a median of $27.00 an hour, 7% below the US median of $29.12. The middle half of them earn between $21.95 and $33.85 an hour. About 510 work in the metro. That is 47.4 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 $27.31 an hour, which is 21% above the national $22.66. The middle half of them earn between $21.64 and $37.38 an hour. BLS counts 470 of them working in the area, 43.6 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 $2,050 to the midpoint estimate; the 25th percentile takes off about $1,500. That is a swing of roughly 8.6% to 11.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Columbia has 107,680 jobs in total (BLS, May 2025), ranking 194th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $21.95 | $27.00 | $33.85 | $29.12 | 0.93 | metro |
| Construction laborers (47-2061) | 20% | $21.64 | $27.31 | $37.38 | $22.66 | 1.21 | metro |
