Deck pricing is quoted in a lot of different ways, per square foot, per project, "starting at," which makes it hard to compare one number to another. Here's the actual breakdown by size and material, plus a calculator that adjusts for your specific project.
| Material | Installed cost/sq ft | Maintenance |
|---|---|---|
| Pressure-treated pine | $25-50 | Restain every 1-3 years (Jonesboro's humidity pushes toward the shorter end) |
| Cedar | $30-47 | Reseal roughly annually to every other year in this climate |
| Composite | $35-70, often more for premium lines | Occasional washing, no staining or sealing |
| Size | Square feet | Estimated range |
|---|---|---|
| 10x12 | 120 sq ft | $3,000-$6,000 |
| 12x16 | 192 sq ft | $4,800-$9,600 |
| 16x20 | 320 sq ft | $8,000-$16,000 |
These ranges are planning-level, drawn from the same per-square-foot rates as the estimator above, not a firsthand quote. Elevated decks and railed decks run higher, the estimator adjusts for both.
Repair and refinishing carry their own separate cost logic, not a fraction of new-construction pricing. A single joist repair or replacement typically runs $100-350 per joist, sistering a weakened joist runs $300-1,200 or more per section, and full structural repair (joists, beams, and ledger together) commonly runs $1,500-5,000. Nationally, deck repairs average around $1,465, with most falling between $570 and $2,600. See our deck repair and deck staining and refinishing pages for the full breakdown.
The 2025 Cost vs Value report puts the national average wood deck addition at $18,263, recouping about 94.9% of that at resale, roughly $17,323 back. Composite runs higher upfront, about $25,096 on average, recouping about 88.5%, or roughly $22,199. Both outperform most interior remodeling projects on resale recoup, wood slightly more as a percentage, composite adding more in absolute dollars.
No, it's a planning-level range based on current market per-square-foot rates. A real quote depends on your specific site, soil conditions, and design, and that's what a follow-up conversation is for.
Material cost is the main driver, composite boards themselves cost more than pressure-treated lumber. You're trading a higher upfront number for skipping years of staining and sealing labor.
No, permit fees are separate and vary by town, the estimator shows a permit contact note once you select your town, but the fee itself isn't folded into the cost range since it isn't a construction cost.
