What’s different about Davenport
Davenport sits in the Quad Cities along the Mississippi, where humid summers, hail, and freeze-thaw cycles drive exterior durability needs.
- Footings have to reach below the frost line, so deeper excavation adds cost.
- 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.
