Frequently Asked Questions

A wood deck costs $30-$45 per square foot, while composite decks cost $45-$65 per square foot. A standard 200 sqft wood deck costs $7,000-$10,000, while a composite deck of the same size costs $10,000-$14,000.

Wood decks cost 30-40% less upfront but require annual maintenance (staining, sealing). Composite decks cost more initially but need minimal maintenance and last 25-30 years vs 15-20 for wood. Over 15 years, total costs are similar.

Most jurisdictions require permits for decks over 30 inches high or attached to the house. Permit fees typically range from $200 to $500. Always check with your local building department.
