Cost estimate
Rough installed-cost range for planning only — not a quote. Actual price depends on site conditions, height/complexity, labor, and local rates (sq ft). Get real quotes below.
What affects deck cost
Beyond material and size, cost depends on height above grade, railings and stairs, foundation and footings, built-in features, demolition of an old deck, and local labor rates. Permits are often required. Treat the range as a planning starting point and confirm with quotes.
Frequently asked questions
- How much does it cost to build a deck?
- Typically $15–$50 per square foot installed: pressure-treated wood at the low end, composite at the high end. Enter your deck size and material above for an estimated range.
- Is composite decking worth the extra cost?
- Composite costs more up front but needs far less maintenance than wood and lasts longer, which can pay off over time.
- Does the estimate include labor?
- Yes — these are typical installed costs (materials + labor). They are planning estimates, not quotes.
