- Rot- and mold-resistant or composite materials are favored in humid climates.
- Severe-storm exposure favors impact-resistant materials.
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.
