Homeowners typically see a price gap between composite decking like Trex and traditional wood. The main cost drivers are material price per square foot, installation complexity, and long-term maintenance. Silent impact comes from lifespan, warranty, and upkeep needs that affect total cost of ownership.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Deck Size | $2,000 | $6,000 | $12,000 | Includes framing adjustments |
| Materials Only | $8–$14/sq ft | $14–$25/sq ft | $25–$40+/sq ft | Trex vs wood varies widely |
| Labor & Installation | $4,000 | $8,000 | $16,000 | Per hour rates differ by region |
| Maintenance (5 yrs) | $0 | $500 | $2,000 | Staining, sealing, cleaning |
Overview Of Costs
Cost ranges for a standard 300–400 sq ft deck vary by material: composite Trex typically runs from $25–$40 per square foot installed, while pressure-treated wood runs $15–$25 per square foot installed. A complete project often lands in the $6,000–$16,000 range, with higher-end Trex setups reaching toward $20,000 or more for premium boards and complex layouts. Assumptions: region, deck size, railing style, and substrate conditions.
Cost Breakdown
Understanding the breakdown helps compare Trex and wood beyond sticker price.
| Category | Trex (Low) | Trex (Avg) | Wood (Low) | Wood (Avg) | Notes |
|---|---|---|---|---|---|
| Materials | $12–$20/sq ft | $25–$40/sq ft | $5–$12/sq ft | $8–$20/sq ft | Premium composites vs pine/fir |
| Labor | $4–$8/sq ft | $8–$15/sq ft | $4–$7/sq ft | $6–$12/sq ft | Prepare surface, install joists, railing |
| Equipment | $1–$2/sq ft | $2–$4/sq ft | $1–$2/sq ft | $2–$3/sq ft | |
| Permits | $0–$200 | $200–$500 | $0–$200 | Depends on jurisdiction | |
| Delivery/Disposal | $0–$1,000 | $0–$1,000 | $0–$1,000 | Delivery fees vary by supplier | |
| Warranty | $0–$300 | $0–$600 | $0–$150 | Labor- and material-based |
What Drives Price
Material type and installation complexity are primary price levers. Composite decking costs more upfront due to resin, UV stabilizers, and capped boards that resist staining. Wood costs less initially but may require more frequent staining, sealing, and rot treatment. Labor varies with deck height, stairs, and railing complexity. data-formula=”labor_hours × hourly_rate”>
Cost Components
Different regions show distinct price patterns for Trex and wood. Regional labor markets, material availability, and permit fees shape the final bill. A typical breakdown shows higher material premiums for Trex paired with similar framing costs to wood, while maintenance adds more over time for wood. Assumptions: region, deck size, and railing configuration.
Regional Price Differences
Prices differ by market: Urban, Suburban, and Rural show varying deltas. In the Urban Northeast, Trex tends to be 5–15% higher than rural areas due to delivery and labor rates, while Suburban Midwest often presents mid-range costs for both materials. Expect Trex to push total to the upper band in dense markets, with wood sometimes catching up in regions with cheaper labor. Assumptions: market type and material choice.
Labor, Hours & Rates
Installation time impacts total cost more than many buyers expect. A basic 300–350 sq ft deck may require 3–5 days for framing, decking, railing, and finishing. Labor rates typically range from $45–$85 per hour depending on region and crew experience. Longer runs or stairs increase hours and per-unit costs. Assumptions: crew size, access, and site conditions.
Additional & Hidden Costs
Surprises often appear in permits, drainage, and waste disposal. Some markets require building permits and inspections that add hundreds of dollars. Trex may necessitate more precise cutting and vibration-free fasteners, while wood might need additional rot protection and leak barriers. Budget for bug screens, lighting, and railing upgrades. Assumptions: inspection requirements and add-ons.
Price By Region
Three regional snapshots illustrate range dispersion. West Coast projects often run higher due to material costs and labor. The South typically offers mid-range prices, while the Midwest can be more cost-efficient for framing but variable for specialty finishes. Expect a typical band of ±10–25% around national averages depending on local supply chains. Assumptions: standard 350 sq ft deck, standard railing.
Real-World Pricing Examples
Three scenario cards show applied totals and per-unit costs.
- Basic: 350 sq ft, pressure-treated wood, standard railing, no extras. Labor 40 hours at $60/hour; materials $6,000; total $10,000–$12,000.
- Mid-Range: 350 sq ft, capped composite decking, mid-level railing, simple stairs. Labor 50 hours at $70/hour; materials $10,000–$14,000; total $15,000–$22,000.
- Premium: 420 sq ft, advanced Trex board line, multiple stairs, designer railing, hidden fasteners. Labor 60 hours at $85/hour; materials $14,000–$22,000; total $25,000–$40,000.
Assumptions: region, specs, labor hours.
