Homeowners frequently compare the cost of Trex composite decking to pressure-treated wood, focusing on price, maintenance, and lifespan. The main cost drivers are material price per square foot, installation time, and long-term upkeep. This article provides practical pricing ranges in USD to help buyers form a budget and make an informed choice.
Assumptions: typical residential deck, 300 sq ft footprint, standard 2×6 boards, mid-range railing, Midwest region.
Overview Of Costs
Trex decking generally carries higher upfront costs but can offer lower life-cycle costs due to lower maintenance needs. Pressure-treated wood usually has the lowest initial price but may incur higher maintenance and replacement costs over time. This section lists total project ranges and per-unit estimates with brief assumptions to aid quick budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material (Decking boards, 5/4×6 or 2×6) | $2.50/sq ft | $4.50/sq ft | $8.00/sq ft | Treated wood typical; Trex higher; excludes railing. |
| Total project (300 sq ft) | $1,500 | $3,000 | $9,600 | Includes boards only for scope; installation not included. |
| Installation labor (per sq ft) | $2.00 | $3.50 | $6.00 | Labor varies by region and complexity. |
| Maintenance (annual) | $0.00 | $300 | $600 | Sealing, staining, or cleaning not required for Trex. |
| Materials + Labor 1st year | $3.50/sq ft | $6.00/sq ft | $14.00/sq ft | Range reflects Trex vs PT and inclusion of fasteners/joists. |
Price ranges assume standard deck footprint, basic railing, and no exotic features. Per-unit pricing is provided to support different project sizes and installation realities.
Cost Breakdown
The following table consolidates major cost components and shows how Trex and pressure-treated wood compare across key categories.
| Category | Trex Price Range | PT Wood Price Range | Assumptions | Notes |
|---|---|---|---|---|
| Materials | $6.50-$12.00/sq ft | $2.50-$4.50/sq ft | Includes boards; excludes railing and fasteners | |
| Labor | $2.50-$5.50/sq ft | $1.50-$4.00/sq ft | Typical installation crew rates | |
| Fasteners & Accessories | $0.60-$1.50/sq ft | $0.40-$1.20/sq ft | Composite or stainless options affect cost | |
| Permits/Inspection | $0-$400 | $0-$350 | Local rules may vary | |
| Delivery/Disposal | $0-$150 | $0-$150 | Distance and waste handling | |
| Warranty | $0-$350 | $0-$100 | Trex often includes longer warranties | |
| Taxes & Overhead | $0-$900 | $0-$700 | Regional variance | |
| Contingency | $0-$600 | $0-$500 | Recommended for replacements or tweaks |
Typical installation time also differs; Trex may take longer to cut and fit due to board geometry.
Cost Drivers
Several factors push the price up or down for Trex and pressure-treated wood. The most influential are board profile, edge detail, and required fasteners. Trex boards often require hidden fasteners and compatible hardware, increasing both materials and labor costs. For PT wood, milling, gaps for drainage, and anti-rot treatments can affect pricing. Among niche drivers, deck size, slope, and local code requirements matter significantly.
Pricing Variables
Costs also hinge on regional differences, labor market conditions, and seasonality. Prices tend to rise in spring and early summer and can soften in late fall. Labor efficiency and crew availability can add or subtract from the project total. The following sections detail regional splits, labor time, and potential hidden costs.
Ways To Save
Potential savings include choosing PT lumber with longer lasting pressure treatment, or selecting a lower-profile Trex line with fewer color options. Purchasing materials in advance and coordinating delivery windows can reduce waste and buffer stock costs. In some markets, bulk buying or bundle pricing for decking plus railing yields meaningful discounts. Consider maintenance cycles when evaluating ongoing costs.
Regional Price Differences
Regional variations affect both material and labor prices. In the table below, three markets are contrasted to illustrate typical deltas.
- Coast (Urban): Trex $9.50-$12.50/sq ft; PT $4.00-$6.00/sq ft; labor $4.50-$6.50/sq ft
- Midwest (Suburban): Trex $8.00-$11.50/sq ft; PT $3.50-$5.50/sq ft; labor $3.00-$5.50/sq ft
- Mountain (Rural): Trex $7.00-$10.50/sq ft; PT $3.00-$4.75/sq ft; labor $2.50-$4.75/sq ft
These deltas can be ±10% to ±20% depending on local demand, supply shortages, and contractor pricing.
