What carpenters and the other trades earn in West Virginia
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 6 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.88 for West Virginia.
For carpenters (47-2031, weighted 50%) the local median is $23.42 an hour, which is 20% below the national $29.12. The middle half of them earn between $18.36 and $28.94 an hour. BLS counts 3,670 of them working in the state, 52.3 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.
For cement masons and concrete finishers (47-2051, weighted 10%) the local median is $24.98 an hour, which is 9% below the national $27.41. The middle half of them earn between $19.60 and $28.39 an hour. BLS counts 760 of them working in the state, 10.8 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.
Electricians (47-2111), 10% of the weighting: a median of $31.16 an hour, in line with the US median of $30.38. The middle half of them earn between $23.37 and $40.35 an hour. About 4,290 work in the state. That is 61.1 per 10,000 jobs, compared with 48.7 nationally, which suggests plenty of local crews to bid.
For plumbers, pipefitters and steamfitters (47-2152, weighted 10%) the local median is $27.39 an hour, which is 11% below the national $30.67. The middle half of them earn between $21.16 and $35.44 an hour. BLS counts 1,830 of them working in the state, 26.1 for every 10,000 jobs (US: 30.0), so the local bench is about average.
Drywall and ceiling tile installers (47-2081) carry 10% of the labor weighting. BLS does not publish this trade for West Virginia, so we used the national median: $28.33 an hour against $28.33 for the US. The middle half of them earn between $22.81 and $35.69 an hour.
For roofers (47-2181, weighted 10%) the local median is $24.60 an hour, which is 8% below the national $26.65. The middle half of them earn between $17.44 and $32.09 an hour. BLS counts 440 of them working in the state, 6.3 for every 10,000 jobs (US: 8.7), so the local bench is thinner than average.
A crew paid at the 75th percentile for carpenters ($28.94 an hour) would add about $3,650 to the statewide midpoint; one at the 25th percentile ($18.36) would take off about $3,300. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 701,610 jobs across West Virginia (May 2025), which is 0.5% of US employment.
