Deck & Patio Cost: What to Expect
Deck and patio projects typically run $8,000–$30,000 nationally, averaging around $15,000. Pressure-treated wood decks come in at the lower end; composite and covered structures push toward the top. Here's how contractors price these projects and what moves the number.
What drives deck or patio costs
Understanding what moves the price helps you evaluate whether a quote is genuinely high — or just reflects your specific project's scope.
Size (square footage) — the primary cost driver
Material choice — pressure-treated wood vs. composite vs. concrete
Height and complexity — ground-level vs. elevated decks with stairs
Whether it's covered or has a pergola/roof structure
Permit requirements — most decks over a certain height require permits
A fair quote is about more than the total price
A lower total can actually represent more risk — if it omits items a complete quote should include. Here's what to verify regardless of price.

How do I know if my deck or patio quote is fair?
Compare it with the typical range of $8,000 to $30,000 and check that it covers the same scope as your other quotes. A price far below the range often means missing scope, so ask what is excluded.

Regional pricing variance: Renovation costs vary significantly by location.
