How much does it cost to build a deck?

Pressure-treated decks typically run lower per square foot, cedar mid-range, and composite the most once framing, footings, railing, and stairs are included. Raised decks cost more than ground-level builds.

This calculator shows an honest low–high range because height, grade, railing style, and stairs all move the number. A contractor confirms it on-site.
