Frequently Asked Questions
How much does a deck cost to build?
A basic pressure-treated wood deck costs $15,000–$25,000. Composite decking (Trex, TimberTech) runs $25,000–$45,000+ but requires virtually no maintenance. Size, complexity, and features like stairs and railings affect cost significantly.
Do I need a permit to build a deck?
Yes — most decks require a building permit and structural inspection. Decks attached to the house require proper ledger board connection and flashing. Always hire a contractor who pulls permits — unpermitted decks can be a major issue when selling.
How long does a deck last?
Pressure-treated wood decks last 15–25 years with regular maintenance (staining/sealing every 2–3 years). Composite decking lasts 25–30+ years with minimal maintenance. The structure (posts, joists) typically outlasts the decking surface.
