Deck Cost Guide: Materials, Installation & 2026 Prices

Deck pricing is harder to estimate than most home projects because the same square footage can produce wildly different quotes depending on height, framing complexity, material choice, and what the contractor includes in their base price. The figures below give you a reliable planning baseline across all common materials and sizes.

Deck cost per square foot by material (2026)

MaterialMaterials onlyInstalled (labor + materials)Lifespan
Pressure-treated pine$8–$15/sq ft$15–$35/sq ft15–25 years
Cedar$12–$20/sq ft$20–$40/sq ft20–30 years
Composite (mid-grade)$15–$25/sq ft$25–$50/sq ft25–30 years
Composite (premium)$20–$35/sq ft$35–$60/sq ft30+ years
Hardwood (Ipe, Tigerwood)$20–$40/sq ft$30–$60/sq ft25–50 years
PVC / vinyl$18–$30/sq ft$28–$55/sq ft30+ years

Installed prices include framing lumber, decking boards, fasteners, and labor for a ground-level deck. Elevated decks, stairs, and railings add significant cost. Pressure-treated highlighted as the most common baseline material.

Composite vs pressure-treated: which is worth it

Pressure-treated pine is cheaper upfront and widely available, but it requires sealing or staining every 2–3 years and board replacement is common after 15–20 years. A 320 sq ft deck in pressure-treated costs roughly $4,800–$11,200 installed. The same deck in mid-grade composite runs $8,000–$16,000.

For most homeowners planning to stay in their house for 10 or more years, composite typically wins on total lifetime cost once you factor in maintenance time, staining products, and eventual board replacement. If you are building on a tight budget or planning to sell within 5 years, pressure-treated is the practical choice. Cedar sits between the two and is worth considering if you want a natural wood look with better decay resistance than pine.

Deck cost by region: 2026 US averages

Labour accounts for roughly 50–60% of a deck build cost, which means regional labour markets have a large effect on final quotes. The South and Midwest consistently come in below the national average, while the Northeast and West Coast run significantly higher. Lumber pricing also varies by region, with areas closer to sawmill supply chains in the Southeast and Pacific Northwest tend to see slightly lower framing lumber costs, though the gap has narrowed since the post-pandemic lumber market normalised.

Texas has some of the most competitive deck pricing in the country. Strong contractor supply, long building seasons, and lower general labour costs keep quotes well below the national average. A 16×20 ft deck in pressure-treated that might cost $7,000–$12,000 in New York or Los Angeles typically runs $4,200–$8,300 in Houston or Dallas. Florida and the Southeast follow a similar pattern, though coastal Florida sees some premium from permitting requirements and wind-load engineering on elevated decks.

In the Northeast, shorter deck-building seasons (roughly April through October) compress demand, meaning contractors are heavily booked through summer. This reduces competition at the exact time most homeowners want to build. If you are in a Northern market and your timeline is flexible, getting quotes in late fall for a spring start often produces better pricing than shopping in May or June when contractors have full books.

Frequently Asked Questions

A deck costs $15–$35/sq ft installed for pressure-treated, $25–$50/sq ft for composite, and $30–$60/sq ft for hardwood. A standard 16×20 ft deck runs $4,800–$11,200 in pressure-treated or $8,000–$16,000 in composite, fully installed. Regional variation is significant. See the city pricing table above for location-specific estimates.
A 16×20 ft deck (320 sq ft) costs approximately $4,800–$11,200 installed in pressure-treated pine, $8,000–$16,000 in composite, or $9,600–$19,200 in hardwood. These include framing, decking boards, and labor for a ground-level build. Stairs add $1,000–$3,000, railings add $50–$150 per linear foot, and permits add $100–$1,500 on top.
Pressure-treated is cheaper upfront at $15–$35/sq ft vs $25–$50/sq ft for composite. For a 320 sq ft deck: pressure-treated saves $3,000–$5,000 at installation. Over 10–15 years, composite typically wins on total cost because it needs no staining, sealing, or board replacement. Pressure-treated needs sealing every 2–3 years and boards typically need replacing after 15–20 years.
Deck installation costs $15–$35/sq ft for pressure-treated, $25–$50/sq ft for composite, and $30–$60/sq ft for hardwood. These include framing, decking, fasteners, and labor for a ground-level build. Elevated decks, angled boards, and complex layouts push costs toward the upper end of each range.
A wood deck typically returns 60–75% of its cost at resale. Composite returns slightly less upfront but holds value better over time due to lower maintenance. A well-built deck in good condition adds meaningful appeal in most US markets, particularly in the South, Midwest, and suburban Northeast where outdoor living space is a strong selling point.
This calculator estimates cost based on deck area and material type. It does not include permits ($100–$1,500), stairs ($1,000–$3,000 per staircase), railings ($50–$150/linear ft), demo of existing deck ($5–$10/sq ft), elevated deck framing premiums (+$15–$30/sq ft), or site-specific structural requirements.
