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)
| Material | Materials only | Installed (labor + materials) | Lifespan |
|---|---|---|---|
| Pressure-treated pine | $8–$15/sq ft | $15–$35/sq ft | 15–25 years |
| Cedar | $12–$20/sq ft | $20–$40/sq ft | 20–30 years |
| Composite (mid-grade) | $15–$25/sq ft | $25–$50/sq ft | 25–30 years |
| Composite (premium) | $20–$35/sq ft | $35–$60/sq ft | 30+ years |
| Hardwood (Ipe, Tigerwood) | $20–$40/sq ft | $30–$60/sq ft | 25–50 years |
| PVC / vinyl | $18–$30/sq ft | $28–$55/sq ft | 30+ 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.
Deck cost by size (installed)
| Deck size | Area | Pressure-treated | Composite | Hardwood |
|---|---|---|---|---|
| Small (10×12 ft) | 120 sq ft | $1,800–$4,200 | $3,000–$6,000 | $3,600–$7,200 |
| Medium (12×16 ft) | 192 sq ft | $2,880–$6,720 | $4,800–$9,600 | $5,760–$11,520 |
| Standard (16×20 ft) | 320 sq ft | $4,800–$11,200 | $8,000–$16,000 | $9,600–$19,200 |
| Large (20×24 ft) | 480 sq ft | $7,200–$16,800 | $12,000–$24,000 | $14,400–$28,800 |
Standard 16x20 ft highlighted as the most common residential deck size. Prices include framing, decking, and labor for a ground-level build. Excludes stairs, railings, and permits.
What affects deck cost
| Factor | Typical cost impact | Notes |
|---|---|---|
| Elevated deck (2nd story) | +$15–$30/sq ft | More complex framing, longer posts, engineering |
| Stairs | +$1,000–$3,000 | Per staircase, depending on height and width |
| Railings | +$50–$150/linear ft | Wood cheaper, cable and glass railing cost more |
| Permits | $100–$1,500 | Most decks over 30 inches require a permit |
| Demo of existing deck | +$5–$10/sq ft | Removal and disposal of old structure |
| Regional labor rates | ±30–50% | South and Midwest lower; Northeast and West Coast higher |
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.
| Region | States | Pressure-treated (per sq ft) | Composite (per sq ft) |
|---|---|---|---|
| Southeast | FL, GA, NC, SC, TN | $14–$28 | $23–$42 |
| South Central | TX, OK, AR, LA | $13–$26 | $22–$40 |
| Midwest | OH, MI, IL, IN, WI | $16–$30 | $25–$46 |
| Mid-Atlantic | PA, VA, MD, NJ | $18–$34 | $28–$52 |
| Mountain West | CO, AZ, NV, UT | $16–$32 | $26–$48 |
| Northeast | NY, MA, CT, RI | $22–$38 | $33–$58 |
| West Coast | CA, WA, OR | $24–$42 | $36–$62 |
Installed per sq ft for a ground-level deck including framing, boards, fasteners, and labor. Excludes stairs, railings, and permits. South Central highlighted as lowest-cost region nationally.
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.
