When to Hire a Deck & Patio Builder

Hire a deck/patio contractor for new construction or structural repairs. Simple board replacement can be DIY, but structural issues, new construction, or anything involving ledger boards attached to your house requires professional expertise. Most deck projects require permits and must meet specific code requirements for safety.

Questions to Ask Before Hiring

• Do you pull permits and schedule inspections?
• What material options do you recommend (wood, composite, aluminum)?
• How do you attach the ledger board to my house to prevent water damage?
• What is the expected lifespan of different material options?
• Can you design for my specific lot conditions (slope, trees, etc.)?
• What footings does St. Louis code require for my project?
• Do you offer any warranties beyond material manufacturers?

Red Flags to Watch For

• Suggests skipping permits to save money
• Doesn't discuss ledger board attachment method
• No engineering for elevated or multi-level decks
• Uses undersized framing or inadequate footings
• Cannot explain code requirements for railings and stairs
• Doesn't discuss drainage under deck
• No examples of permitted and inspected projects
