Extras are quoted nationally and then scaled to Charleston by the average of the local wage index (0.85) and goods index (0.96), a factor of 0.91. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.

When to schedule wood deck in Charleston
We use NOAA's 1991-2020 climate normals for Charleston City (5 miles from the city center). These are 30-year monthly averages, not forecasts.
Weather is not a serious constraint for exterior installation in Charleston: no month in the averages is cold enough (an average daytime high under 45°F) or hot enough (an average daytime high of 90°F or more) to rule it out, so the workable window is all year.
Charleston gets about 44 inches of precipitation in a normal year. The wettest months are July, August and September (6.1 inches in August). The station averages about 25 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Charleston is 0.85 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $24.22 an hour, which is 17% below the national $29.12. The middle half of them earn between $21.37 and $29.52 an hour. BLS counts 1,240 of them working in the area, 31.5 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $20.98 an hour, 7% below the US median of $22.66. The middle half of them earn between $18.00 and $24.49 an hour. About 3,710 work in the metro. That is 94.1 per 10,000 jobs, compared with 70.5 nationally, which suggests plenty of local crews to bid.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($29.52 an hour) instead of the median, the labor line grows by about $720. At the 25th percentile ($21.37) it shrinks by about $390. The total moves by 6.9% or 3.7%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 394,170 jobs in the Charleston-North Charleston area. That makes it the 66th largest of the 300 metros we cover, with 0.25% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $21.37 | $24.22 | $29.52 | $29.12 | 0.83 | metro |
| Construction laborers (47-2061) | 20% | $18.00 | $20.98 | $24.49 | $22.66 | 0.93 | metro |
