Composite deck: what moves the price in Florence
Engineering
Large or complex decks may need a structural engineer at $100-$220 an hour to get a permit.
Board grade
Composite materials run $16-$32 per sq ft and the installed price is $40-$80 per sq ft, including the substructure (HomeGuide).
Labor
Labor for composite is $24-$48 per sq ft, higher than wood because the boards need extra parts and more careful assembly.
What local crews earn in Florence
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 Florence the blend is 0.84.
Carpenters (47-2031), 80% of the weighting: a median of $23.68 an hour, 19% below the US median of $29.12. The middle half of them earn between $19.36 and $31.04 an hour. About 130 work in the metro. That is 14.6 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 $21.75 an hour, which is 4% below the national $22.66. The middle half of them earn between $18.11 and $26.11 an hour. BLS counts 650 of them working in the area, 73.0 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 $2,200 to the midpoint estimate; the 25th percentile takes off about $1,300. That is a swing of roughly 8.0% to 13.5% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Florence has 89,060 jobs in total (BLS, May 2025), ranking 221st by size among the 300 metros on this site.
