Why two Sebastian quotes can differ
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.
Sebastian weather and the composite deck calendar
Climate numbers on this page come from NOAA's 1991-2020 U.S. Climate Normals at the nearest suitable station, Vero Beach Intl Ap (15 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 Sebastian are September through June: 10 of 12. Outside them, July and August have an average daytime high of 90°F or more.
Sebastian gets about 53 inches of precipitation in a normal year. The wettest months are June, August and September (7.3 inches in August). Inside the workable window, February and December are the driest, at 2.2 and 2.5 inches. The station averages about 72 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.

What local crews earn in Sebastian
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 Sebastian the blend is 0.83.
Carpenters (47-2031), 80% of the weighting: a median of $23.24 an hour, 20% below the US median of $29.12. The middle half of them earn between $20.80 and $28.17 an hour. About 360 work in the metro. That is 62.5 per 10,000 jobs, compared with 43.1 nationally, which suggests plenty of local crews to bid.
For construction laborers (47-2061, weighted 20%) the local median is $21.68 an hour, which is 4% below the national $22.66. The middle half of them earn between $17.92 and $23.00 an hour. BLS counts 480 of them working in the area, 83.3 for every 10,000 jobs (US: 70.5), so the local bench is deeper than average.
A quick sensitivity check: moving the lead trade (carpenters) from the median to the 75th percentile wage adds about $1,450 to the midpoint estimate; the 25th percentile takes off about $720. That is a swing of roughly 4.5% to 9.1% of the total, which is useful for judging whether a bid reflects wages or something else, such as scope or margin.
