When Mississippi weather lets you build
Weather decides when exterior installation can happen, and Mississippi is not uniform. The table uses NOAA's 1991-2020 climate normals from the weather station nearest each metro we cover, and counts the months that are neither cold nor hot enough to complicate the job.
Gulfport has the longest comfortable season of the metros we cover in Mississippi at 10 months (September through June); Hattiesburg has the shortest at 9 (September through May). Rainfall runs from 51 inches a year in Jackson to 63 inches in Gulfport.
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 |
|---|---|---|---|---|
| Jackson | 38 | 92 | 51 | 9: September through May |
| Gulfport | 42 | 90 | 63 | 10: September through June |
| Hattiesburg | 38 | 92 | 59 | 9: September through May |

Mississippi labor market for composite deck
Mississippi's labor line is priced from 2 trades, each compared with its US median wage. After weighting by each trade's share of the work, the state comes out at 0.80 times the national level.
Carpenters (47-2031), 80% of the weighting: a median of $23.39 an hour, 20% below the US median of $29.12. The middle half of them earn between $18.47 and $25.23 an hour. About 2,950 work in the state. That is 25.4 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 $18.13 an hour, which is 20% below the national $22.66. The middle half of them earn between $16.25 and $22.01 an hour. BLS counts 8,800 of them working in the state, 75.7 for every 10,000 jobs (US: 70.5), so the local bench is about average.
A crew paid at the 75th percentile for carpenters ($25.23 an hour) would add about $550 to the statewide midpoint; one at the 25th percentile ($18.47) would take off about $1,450. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.
BLS counts 1,163,030 jobs across Mississippi (May 2025), which is 0.7% of US employment.
| Trade | Weight | 25th pct | Median | 75th pct | US median | Ratio | Level used |
|---|---|---|---|---|---|---|---|
| Carpenters (47-2031) | 80% | $18.47 | $23.39 | $25.23 | $29.12 | 0.80 | state |
| Construction laborers (47-2061) | 20% | $16.25 | $18.13 | $22.01 | $22.66 | 0.80 | state |

Add-ons priced for Mississippi
Add-ons start from national price ranges and are scaled by 0.88 for Mississippi, which is the average of the area's wage index (0.80) and goods price index (0.96). The estimator above can add them to your total.
| Add-on | Local range |
|---|---|
| Add a deck railing (approx. 0.3 ft per sq ft) | $1,600 – $4,750 |
Mississippi metro-by-metro prices
2 of the 3 metros sit above the statewide midpoint of $15,700, and the top-to-bottom gap is 2%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.
| Metro | Range (300 sq ft) | Midpoint | vs. state |
|---|---|---|---|
| Gulfport, MS | $10,600 – $21,200 | $15,900 | +1% |
| Jackson, MS | $10,500 – $21,100 | $15,800 | +1% |
| Hattiesburg, MS | $10,400 – $20,700 | $15,600 | −1% |

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