What affects your deck price
Price range
A new deck costs about $4,339 to $12,652. Permits add about $230 to $500. Not a quote or an offer. Your price comes from the builder. Source: Angi, 2026.
What moves the number
- Size. Bigger decks need more boards, posts and hours.
- Material. Pressure-treated wood costs the least. Composite costs more up front but doesn't need staining.
- Height. A deck off a second floor needs taller posts and more safety work.
- Your yard. Slopes make building harder.
- Extras. Stairs, railings, built-in benches and lights all add cost.
What to ask before you choose
- "How will you attach the deck to my house?" The board that connects the deck to the house is called the ledger. It needs bolts, not just nails, and flashing to keep water out.
- "Does the price include stairs and railings?"
- "Who pulls the permit and schedules the inspection?" It should be the builder.
- "What warranty do I get on the boards and on your work?"
- "How often will I need to seal or stain it?"
The catch: when decks fail, it's often where they attach to the house. Ask your builder to show you how they'll do it. Also, tell your home insurance company about the new deck. It adds value to your home, and your coverage may need to go up.
