Deck Cost Buying Guide 2026
📐
Right-size your deck
Most decks are over-built. A 300–400 sq ft deck serves most households well. Going bigger adds cost fast — especially for elevated decks where every square foot needs posts, beams, and footings.
🌿
Composite pays off long-term
Pressure treated wood is cheaper upfront but requires staining every 2 years. Composite costs more initially but saves roughly $500/year in maintenance and lasts 25–30 years vs 10–15 for PT wood.
🏗️
Get 3 contractor bids
Labor prices for deck work vary 30–40% between contractors in the same city. Always get at least 3 bids before committing. Ask for references and verify license and insurance.
📅
Build in late fall or winter
Contractors are less busy October through February. You can often negotiate 10–20% lower labor costs outside of peak season, and permits are typically processed faster too.
🔩
Supply your own hardware
Buying your own fasteners, screws, and joist hangers from a big-box store can save 15–25% vs contractor-supplied materials. Confirm with your contractor they allow owner-supplied materials.
Frequently Asked Questions
How much does a 400 sq ft deck cost in 2026?
A 400 sq ft deck typically costs $9,000–$21,000 depending on material and location. Composite decking in the $11,000–$15,000 range is the most common choice. Elevated decks or luxury finishes can push costs to $28,000+.
What is the cheapest deck material?
Pressure treated (PT) wood is the cheapest at $15–$30/sq ft installed. However, it requires annual maintenance and typically lasts 10–15 years. Composite costs more upfront but is cheaper over a 20-year period when maintenance is factored in.
Does deck size affect cost per square foot?
Yes. Smaller decks (under 200 sq ft) often cost more per square foot because fixed costs like permits, post installation, and equipment are spread across fewer square feet. Larger decks benefit from economies of scale.
Do I need a permit to build a deck?
Most jurisdictions require a permit for decks over 200 sq ft or elevated more than 30 inches. Permit costs range from $150–$500. Always check with your local building department before starting.
How long does it take to build a deck?
A typical 300–500 sq ft deck takes 3–7 days for an experienced crew. Larger decks or those with complex features like multiple levels, pergolas, or built-in features can take 2–3 weeks.
How accurate is this deck cost calculator?
