The article examines the cost differences between Trex composite decking and traditional pressure-treated wood, focusing on the price to buy and install, plus long-term value. Key cost drivers include material pricing, installation labor, and maintenance needs. Understanding cost drivers helps buyers estimate total deck costs more accurately.

| Labor & installation (per 100 sq ft) | $1,000 | $2,000 | $4,000 | Includes framing adjustments |
| Hardware & fasteners (per 100 sq ft) | $50 | $150 | $300 | Stainless/CCA alternatives |
| Permits & inspections | $0 | $150 | $500 | Varies by city |
| Delivery/Disposal | $50 | $150 | $350 | Site disposal fees may apply |
| 5-year maintenance (coatings, sealants) | $0 | $200 | $600 | Trex has lower sealing needs |
Assumptions: region, deck size, railing choices, slope, and crew availability.
Overview Of Costs
Trex decking generally costs more upfront but can offer lower maintenance over time, while pressure-treated wood has a lower initial price but higher ongoing upkeep. This section provides total project ranges and per-unit ranges with typical assumptions for a mid-range 300–400 sq ft deck, including railing and basic stairs. Trex typically runs higher per sq ft due to material and coatings, whereas PT wood may need yearly sealants and more frequent staining.
Cost Breakdown
Material, labor, and ancillary costs collectively shape the final price. The table below organizes costs by category and shows typical ranges for Trex vs pressure-treated wood per 100 sq ft and for a full 300–400 sq ft project when applicable.
| Category | Trex (per 100 sq ft) | Pressure-Treated (per 100 sq ft) | Assumptions | Notes |
|---|---|---|---|---|
| Materials | $1,200–$3,000 | $180–$600 | Composite vs wood | Includes boards, fascia, and trim |
| Labor | $900–$1,900 | $700–$1,600 | Framing, decking, fasteners | Per 100 sq ft; labor hours depend on slope |
| Equipment | $50–$150 | $40–$120 | Rental or tool use | Cutters, drills, saws |
| Permits | $50–$350 | $0–$250 | Local rules | Some jurisdictions require permits |
| Delivery/Disposal | $50–$150 | $50–$150 | Delivery to site | Disposal fees may apply |
| Warranty | $0–$200 | $0–$100 | Material warranty | Trex often includes longer warranties |
| Contingency | $100–$400 | $100–$400 | Unforeseen fixes | 10–15% typical |
| Taxes | $60–$180 | $0–$60 | State tax impact | Depends on local rates |

What Drives Price
Material quality, installation complexity, and regional costs are the primary price drivers. For Trex, higher-grade decking, color blends, and non-slip surfaces add to the material cost. Pressure-treated wood varies by species (e.g., Southern yellow pine vs. fir) and treatment level. Labor costs swing with site access, deck height, stair counts, and drainage considerations. Local labor rates may be 5–15% higher in urban areas.
Ways To Save
Save by choosing standard profiles, planning for efficient installation, and timing work during off-peak demand. Savings tactics include selecting standard Trex colors or opting for 5/4 decking rather than premium lines, bundling railing and lighting, and coordinating permits to avoid rush fees. Maintenance plans with PT wood can reduce long-term refresh costs if a stain-and-seal cycle is planned every few years.
Regional Price Differences
Prices vary by region due to material availability, labor markets, and local codes. Compare three U.S. regions to gauge typical deltas: Northeast, Midwest, and South. Trex material costs tend to be higher in the Northeast due to shipping and demand, while labor rates may exceed the national average in urban coastal markets. PT wood often has lower material costs in Southern regions where pine is abundant, but increases if treated with higher-grade preservatives.
Real-World Pricing Examples
Three scenario cards illustrate typical quotes for common deck sizes and configurations.
- Basic: 150 sq ft PT wood deck with minimal railing and one set of stairs. Materials: $300–$450; Labor: $900–$1,300; Permits/Delivery: $0–$100; Total: $1,200–$1,900.
- Mid-Range: 250 sq ft Trex deck with standard railing and two stair runs. Materials: $2,000–$3,000; Labor: $1,400–$2,300; Permits/Delivery: $100–$300; Total: $3,500–$5,600.
- Premium: 400 sq ft Trex deck with upgraded railing, lighting, and integrated drainage. Materials: $4,800–$7,000; Labor: $2,800–$4,500; Permits/Delivery: $300–$600; Total: $7,900–$12,100.
Assumptions: standard slope, access, and no structural upgrades.
Maintenance & Ownership Costs
Ongoing costs differ substantially between Trex and PT wood over five years. Trex typically requires little to no staining or sealing, translating to lower maintenance costs. PT wood usually demands annual or biennial sealing or staining, plus higher rot- and insect-protection considerations. A five-year cost outlook often shows Trex with a lower cumulative maintenance expense, despite higher upfront pricing.
Cost By Region
Regional differences influence both material and labor pricing. In the Northeast and West Coast, expect higher labor rates and possible lead times, while the Midwest and South may offer more competitive pricing. Regional swings can add or subtract 10–20% from installed project totals depending on crew availability and material sourcing.
Pricing FAQ
Common price questions answered with quick estimates. How much more does Trex cost upfront? Typically 30–60% higher per sq ft than PT wood, depending on the line and color. Is PT wood cheaper long-term? It can be cheaper upfront, but maintenance costs accrue and can narrow the long-term gap. Do permits add a lot? Permits vary; some areas require none, others add 5–15% to the project total.
