What’s different about Miami
Miami's strict hurricane wind codes, dense permitting, coastal salt air, and high cost of living make it Florida's most expensive exterior market.
- Wind-uplift detailing and stronger connectors are common near the coast.
- Rot- and mold-resistant or composite materials are favored in humid climates.
- Salt air favors corrosion-resistant materials and fasteners.
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.
