The cost to build a deck varies by material, size, and installation requirements. Trex (composite) decks generally cost more upfront but may reduce long-term maintenance, while traditional wood decks are cheaper initially but can incur higher upkeep. Price ranges below reflect typical U.S. markets for mid-range installations.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trex Decking Material | $3.50/sq ft | $6.50/sq ft | $12.00+/sq ft | Includes basic boards; higher grades, colors, and capped profiles raise cost |
| Wood Decking Material | $1.50/sq ft | $3.50/sq ft | $6.50+/sq ft | Common species: pressure-treated pine to tropical hardwoods |
| Labor (Decking, Installation) | $4.00/sq ft | $7.50/sq ft | $15.00+/sq ft | Labor varies by layout complexity and substructure work |
| Railings & Accessories | $8-$25/linear ft | $25-$50/linear ft | $60+/linear ft | Includes posts, caps, balusters, and fasteners |
| Total Installed Deck (30×12 ft) | $7,000 | $14,000 | $28,000+ | Assumes standard framing, footings, and basic elevation changes |
Assumptions: region, deck size, access, and local labor rates vary.
Overview Of Costs
Overview: Trex typically costs more for materials but can reduce maintenance expenses over time; wood costs less upfront but may incur higher upkeep and staining. This section provides total project ranges and per-unit ranges with brief assumptions to help buyers estimate budgets for a standard backyard deck.
Cost Breakdown
Table summarizes major cost categories for both materials and labor. Use this as a quick budgeting guide; actual bids may differ by region and project specifics.
| Category | Trex (Low) | Trex (Avg) | Wood (Low) | Wood (Avg) | Notes |
|---|---|---|---|---|---|
| Materials | $2.50/sq ft | $6.50/sq ft | $1.20/sq ft | $3.50/sq ft | Board type and profile matter |
| Labor | $4.00/sq ft | $7.50/sq ft | $3.00/sq ft | $6.50/sq ft | Includes framing and substructure |
| Permits | $0-$500 | $0-$500 | $0-$500 | Depends on locality | |
| Delivery/Disposal | $0-$300 | $0-$300 | $0-$300 | Board quantity affects cost | |
| Warranty | $0-$200 | $0-$200 | $0-$150 | Material vs contractor warranty | |
| Taxes | Varies | Varies | Varies | State and local rates apply |

What Drives Price
Key drivers include material selection, deck size, and the substructure requirements. For Trex, color and profile (adequate protection against fading) can add cost; for wood, species selection and hardness affect price and durability. Other drivers include slope, access, and removal of an existing deck.
Regional Price Differences
Prices vary by region due to labor markets and material transport. Compare three general market types to understand deltas: Urban, Suburban, and Rural.
- Urban: Trex installed typically 10–15% higher than average due to higher labor rates and material access challenges.
- Suburban: Moderate cost range; Trex often 5–10% higher than wood, depending on profiles chosen.
- Rural: Wood may be notably cheaper; Trex could still be costlier due to limited supply and delivery charges.
Labor & Installation Time
Labor costs rely on crew size and project duration. A 30×12 ft deck commonly requires 2–4 days of work for framing, decking, and railing installations. For Trex, expect longer cut times and more specialized fasteners, which can raise per-square-foot labor costs by a few dollars.
Real-World Pricing Examples
Three scenario cards illustrate typical bids. Each reflects common layouts, species, and feature sets.
-
Basic: 30×12 ft, basic framing, Trex Lineage boards, standard railing, no extra features.

- Total: around $40,000–$65,000
Maintenance & Ownership Costs
Maintenance costs differ sharply between Trex and wood over time. Trex typically requires periodic cleaning and occasional sealants only if needed by color or finish, reducing repainting and staining frequency. Wood decks may require annual sealing or staining, plus stain-remix color refreshes every 2–4 years. A 5-year cost outlook shows Trex often lower in upkeep despite higher initial spend.
