Optional extras in Gulfport
Extras are quoted nationally and then scaled to Gulfport by the average of the local wage index (0.82) and goods index (0.96), a factor of 0.89. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.

Why two Gulfport quotes can differ
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.
Drainage
Ground-level decks over poorly draining yards may need $1,000-$4,000 of drainage work first.
Gulfport labor market for composite deck
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Gulfport is 0.82 times the national level.
For carpenters (47-2031, weighted 80%) the local median is $23.78 an hour, which is 18% below the national $29.12. The middle half of them earn between $21.51 and $25.23 an hour. BLS counts 530 of them working in the area, 33.5 for every 10,000 jobs (US: 43.1), so the local bench is thinner than average.
Construction laborers (47-2061), 20% of the weighting: a median of $18.69 an hour, 18% below the US median of $22.66. The middle half of them earn between $16.86 and $22.67 an hour. About 1,090 work in the metro. That is 68.9 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the carpenters on your job are paid at the 75th percentile ($25.23 an hour) instead of the median, the labor line grows by about $430. At the 25th percentile ($21.51) it shrinks by about $670. The total moves by 2.7% or 4.2%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 158,310 jobs in the Gulfport-Biloxi area. That makes it the 149th largest of the 300 metros we cover, with 0.10% of US employment.
