The wage side of the estimate leans on carpenters, who do 80% of the hours on a typical job. Their local median is $27.17 an hour. Add the other trades involved and the blended wage index for Louisville is 0.95 (US = 1.00), which puts labor at 59% of the total.
Materials are scaled with BEA's regional price parity for goods. Louisville is at 96.2 against 100 for the US, so a materials line of $7,200 nationally becomes $6,950 here (midpoint, 300 sq ft). Permits follow the all-items index of 93.1: $45 to $140.
Who does the work: Louisville trade wages
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 Louisville the blend is 0.95.
Carpenters (47-2031), 80% of the weighting: a median of $27.17 an hour, 7% below the US median of $29.12. The middle half of them earn between $23.31 and $31.24 an hour. About 2,990 work in the metro. That is 43.6 per 10,000 jobs, compared with 43.1 nationally, so the supply of crews looks typical.
For construction laborers (47-2061, weighted 20%) the local median is $22.80 an hour, which is in line with the national $22.66. The middle half of them earn between $18.98 and $28.03 an hour. BLS counts 4,600 of them working in the area, 67.1 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 $1,200 to the midpoint estimate; the 25th percentile takes off about $1,150. That is a swing of roughly 6.6% to 7.0% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
Louisville/Jefferson County has 685,190 jobs in total (BLS, May 2025), ranking 43rd by size among the 300 metros on this site.

The best months for composite deck in Louisville
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Louisville Intl Ap (5 miles from the city center). They are 30-year averages, so any one year can run hotter, colder or wetter.
For exterior installation, the comfortable months in Louisville are February through December: 11 of 12. Outside them, January has an average daytime high under 45°F.
In January the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.
Louisville gets about 48 inches of precipitation in a normal year, including roughly 13 inches of snow. The wettest months are March, April and May (5.2 inches in May). Inside the workable window, February and November are the driest, at 3.4 and 3.4 inches. The station averages about 43 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.

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.
