What local crews earn in Deltona
The labor line is built from BLS wage data, one trade at a time. This job draws on 6 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 Deltona the blend is 0.79.
Carpenters (47-2031), 50% of the weighting: a median of $22.44 an hour, 23% below the US median of $29.12. The middle half of them earn between $17.85 and $27.17 an hour. About 740 work in the metro. That is 33.7 per 10,000 jobs, compared with 43.1 nationally, so expect fewer local crews to bid.
Cement masons and concrete finishers (47-2051), 10% of the weighting: a median of $23.08 an hour, 16% below the US median of $27.41. The middle half of them earn between $21.21 and $27.43 an hour. About 330 work in the metro. That is 15.0 per 10,000 jobs, compared with 13.3 nationally, so the supply of crews looks typical.
For electricians (47-2111, weighted 10%) the local median is $23.54 an hour, which is 23% below the national $30.38. The middle half of them earn between $22.25 and $28.33 an hour. BLS counts 1,140 of them working in the area, 51.9 for every 10,000 jobs (US: 48.7), so the local bench is about average.
Plumbers, pipefitters and steamfitters (47-2152), 10% of the weighting: a median of $24.28 an hour, 21% below the US median of $30.67. The middle half of them earn between $21.60 and $29.86 an hour. About 710 work in the metro. That is 32.3 per 10,000 jobs, compared with 30.0 nationally, so the supply of crews looks typical.
For drywall and ceiling tile installers (47-2081, weighted 10%) the local median is $22.93 an hour, which is 19% below the national $28.33. The middle half of them earn between $19.24 and $24.90 an hour. BLS counts 140 of them working in the area, 6.4 for every 10,000 jobs (US: 5.3), so the local bench is deeper than average.
Roofers (47-2181), 10% of the weighting: a median of $22.57 an hour, 15% below the US median of $26.65. The middle half of them earn between $17.96 and $29.25 an hour. About 580 work in the metro. That is 26.4 per 10,000 jobs, compared with 8.7 nationally, which suggests plenty of local crews to bid.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $3,100 to the midpoint estimate; the 25th percentile takes off about $3,000. That is a swing of roughly 6.2% to 6.4% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
