Weather windows across Kentucky
Season matters for composite deck. For each Kentucky metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for exterior installation.
Every Kentucky metro on the list has 11 comfortable months, though rainfall ranges from 48 inches a year in Louisville to 50 in Bowling Green.
We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.
| Metro | Jan avg low °F | Jul avg high °F | Precip (in/yr) | Comfortable months |
|---|---|---|---|---|
| Louisville | 28 | 89 | 48 | 11: February through December |
| Lexington | 25 | 87 | 50 | 11: February through December |
| Bowling Green | 28 | 90 | 50 | 11: August through June |

What carpenters and the other trades earn in Kentucky
Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 2 trades drive the labor line for this job, and the weighted ratio against the national wage level is 0.89 for Kentucky.
For carpenters (47-2031, weighted 80%) the local median is $25.33 an hour, which is 13% below the national $29.12. The middle half of them earn between $22.09 and $29.45 an hour. BLS counts 8,540 of them working in the state, 42.7 for every 10,000 jobs (US: 43.1), so the local bench is about average.
Construction laborers (47-2061), 20% of the weighting: a median of $21.98 an hour, 3% below the US median of $22.66. The middle half of them earn between $18.13 and $24.06 an hour. About 13,280 work in the state. That is 66.4 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
A crew paid at the 75th percentile for carpenters ($29.45 an hour) would add about $1,200 to the statewide midpoint; one at the 25th percentile ($22.09) would take off about $960. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 2,000,360 jobs across Kentucky (May 2025), which is 1.3% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $22.09 | $25.33 | $29.45 | $29.12 | 0.87 | state |
| Construction laborers (47-2061) | 20% | $18.13 | $21.98 | $24.06 | $22.66 | 0.97 | state |

Composite deck: what moves the price in Kentucky
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

Engineering
Large or complex decks may need a structural engineer at $100-$220 an hour to get a permit.

Extras are quoted nationally and then scaled to Kentucky by the average of the local wage index (0.89) and goods index (0.96), a factor of 0.92.
