Why Charleston prices look the way they do
We price the labor side from BLS wage data for 3 trades: plumbers, pipefitters and steamfitters at 40%, construction laborers at 40%, operating engineers and other construction equipment operators at 20%. Weighted together, Charleston wages are 0.90 times the national level. Labor makes up about 50% of the midpoint estimate (52% at national prices).
Materials are scaled with BEA's regional price parity for goods. Charleston is at 96.3 against 100 for the US, so a materials line of $3,350 nationally becomes $3,250 here (midpoint, 4,000 sq ft of lawn). Permits follow the all-items index of 101.0: $0 to $0.
Who does the work: Charleston trade wages
The labor line is built from BLS wage data, one trade at a time. This job draws on 3 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 0.90.
Plumbers, pipefitters and steamfitters (47-2152), 40% of the weighting: a median of $27.58 an hour, 10% below the US median of $30.67. The middle half of them earn between $23.50 and $31.15 an hour. About 960 work in the metro. That is 24.4 per 10,000 jobs, compared with 30.0 nationally, so expect fewer local crews to bid.
For construction laborers (47-2061, weighted 40%) the local median is $20.98 an hour, which is 7% below the national $22.66. The middle half of them earn between $18.00 and $24.49 an hour. BLS counts 3,710 of them working in the area, 94.1 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
Operating engineers and other construction equipment operators (47-2073), 20% of the weighting: a median of $24.35 an hour, 15% below the US median of $28.78. The middle half of them earn between $23.39 and $29.69 an hour. About 1,470 work in the metro. That is 37.3 per 10,000 jobs, compared with 30.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (plumbers, pipefitters and steamfitters) from the median to the 75th percentile wage adds about $170 to the midpoint estimate; the 25th percentile takes off about $190. That is a swing of roughly 3.0% to 2.6% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Charleston-North Charleston has 394,170 jobs in total (BLS, May 2025), ranking 66th by size among the 300 metros on this site.

The best months for sprinkler system in Charleston
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Charleston City (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
Weather is not a serious constraint for digging, grading and setting material in the ground in Charleston: no month in the averages is cold enough (an average overnight low at or below freezing (32°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.
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.
