What’s different about Louisiana
Louisiana's hurricane risk drives wind-rated construction, and persistent humidity and flood exposure raise exterior maintenance and insurance-related costs.
- Wind-uplift detailing and stronger connectors are common near the coast.
- Rot- and mold-resistant or composite materials are favored in humid climates.
Expect quotes toward the higher end in Louisiana’s larger metros — New Orleans, Baton Rouge, and Shreveport — where labor and permit costs run above the state average, and lower in rural areas.
How the cost is built
Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.
Resale value
A wood deck recoups about 50–83% of its cost at resale — more than a composite deck — according to the annual Remodeling Cost vs. Value report.
