Charleston 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, Charleston Yeager Ap (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 Charleston are February through December: 11 of 12. Outside them, January has an average daytime high under 45°F.
In January 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.
Charleston gets about 46 inches of precipitation in a normal year, including roughly 32 inches of snow. The wettest months are May, June and July (5.4 inches in July). Inside the workable window, October and November are the driest, at 2.9 and 3.2 inches. The station averages about 24 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 Charleston
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 Charleston the blend is 0.85.
Carpenters (47-2031), 80% of the weighting: a median of $23.59 an hour, 19% below the US median of $29.12. The middle half of them earn between $18.33 and $29.48 an hour. About 370 work in the metro. That is 35.8 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $22.97 an hour, which is in line with the national $22.66. The middle half of them earn between $17.31 and $28.79 an hour. BLS counts 660 of them working in the area, 63.8 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 $1,750 to the midpoint estimate; the 25th percentile takes off about $1,550. That is a swing of roughly 9.6% to 10.8% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Charleston has 103,450 jobs in total (BLS, May 2025), ranking 199th by size among the 300 metros on this site.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
