Homeowners typically pay a wide range for replacing a wood deck with Trex composite, driven by deck size, substructure condition, select Trex line, and removal needs. The total often includes materials, labor, permits, and disposal. cost and price transparency helps buyers compare options and set a realistic budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (Trex decking + fasteners) | $3,500 | $8,000 | $12,000 | Includes standard boards and hidden fasteners |
| Labor & installation | $2,500 | $6,000 | $9,000 | Based on 100–180 hours |
| Demolition & disposal | $300 | $1,200 | $2,500 | Old decking and framing removal |
| Permits & inspections | $0 | $400 | $1,000 | Permitting varies by municipality |
| Substructure work (if needed) | $500 | $3,500 | $6,000 | Replacing joists, beams, or footings |
| Delivery/Removal of debris | $100 | $400 | $800 | Dumpster or truck haul |
| Warranty & workmanship | $0 | $350 | $800 | Limited vs. extended warranties |
Assumptions: region, deck size, existing framing condition, Trex line, removal scope.
Overview Of Costs
Typical project ranges for replacing a deck with Trex in the U.S. fall between $6,000 and $18,000, depending on size and condition. A smaller 200–300 sq ft deck with minimal framing work might land around $6,000–$9,000, while larger or structurally complex projects can exceed $15,000. The per-square-foot rate commonly ranges from about $25 to $60 plus any necessary substructure improvements. data-formula=”labor_hours × hourly_rate”>
Cost Breakdown
The main cost components are presented below with brief assumptions. Assumptions: region, deck size, board profile, and demolition scope.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $3,500 | $8,000 | $12,000 | Trex Terrain to Trex Transcend; hidden fasteners |
| Labor | $2,500 | $6,000 | $9,000 | Includes framing, decking, railing prep |
| Demolition & disposal | $300 | $1,200 | $2,500 | Old boards, framing, and debris |
| Permits | $0 | $400 | $1,000 | Depends on local codes |
| Substructure work | $500 | $3,500 | $6,000 | Joists, beams, footings |
| Delivery/Disposal | $100 | $400 | $800 | Haul-away fees |
| Warranty | $0 | $350 | $800 | Labor-backed coverage |
Factors That Affect Price
Deck size and slope strongly influence material waste and labor hours, while trex line selection (Entry, Enhanced, or Transcend) changes unit costs. A taller or multi-level deck increases railing and stairwork; a compact design lowers per-square-foot cost. Region, permits, and crew availability also shift final estimates.
Regional Price Differences
Prices vary by geography. In the Northeast, higher labor costs can push totals upward; the Southwest may be closer to the average; the Midwest often offers mid-range pricing. Regional variability can create a ±15–25% swing from the national average. Assumes typical suburban markets with standard permitting.
Labor, Hours & Rates
Labor usually accounts for 40–70% of the project. Typical crew rates range from $50 to $95 per hour, with total hours spanning 80–180 for standard projects. More complex framing or custom railings push hours and costs higher. Labor hours × hourly rate
Additional & Hidden Costs
Hidden factors can raise budgets: structural repairs, drainage changes, or electrical work for lighting. Expect contingencies of 5–15% for unforeseen framing or rot. Permits and disposal fees are sometimes overlooked but can add $200–$2,000. Assumptions: no major foundation issues; standard railing design.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes. Basic covers minimal framing and standard Trex boards; Mid-Range adds higher-grade boards and partial substructure refresh; Premium uses premium Trex lines, custom rails, and full substructure upgrades.
- Basic: 200 sq ft, standard boards, no structural repairs; materials $3,800; labor $2,800; permits $0; total around $6,600.
- Mid-Range: 350 sq ft, enhanced boards, partial joist replacement; materials $6,500; labor $5,000; permits $400; total around $11,900.
- Premium: 450 sq ft, Transcend boards, full framing upgrade, custom railing; materials $9,200; labor $7,500; permits $800; total around $17,500.
Assumptions: region, spec level, access for removal, and railing complexity.
Ways To Save
Shop multiple quotes and compare line-item pricing for materials and labor. Consider standard Trex profiles rather than premium lines to reduce cost 10–25%. If feasible, plan the project in a dry season to minimize weather-related delays. Seasonality & price trends
Maintenance & Ownership Costs
Trex decking generally requires less maintenance than wood, reducing annual upkeep. Expect coatings, cleaners, and occasional board replacements to be far less frequent; a typical 10-year maintenance cost remains substantially lower than wood decks. Lifetime cost of ownership is often lower with Trex due to durability and warranty coverage. 5-year cost outlook: minimal resealing or staining needs.
