Replacing a deck with Trex is a common home improvement project, and buyers typically care about overall cost, price per square foot, and what drives the final number. This article outlines the current Trex deck replacement cost, breaks down the main price components, and notes regional differences and practical ways to save. Expect ranges for materials, labor, permits, and disposal, with concrete examples to help plan a budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trex board material (decking) | $2.50/sq ft | $4.00/sq ft | $6.50/sq ft | Standard Trex line; excludes underlayment |
| Framing material (lumber) | $1.50/sq ft | $2.50/sq ft | $3.50/sq ft | Supports and joists; treated lumber |
| Labor to remove old deck | $2.00/sq ft | $3.50/sq ft | $5.50/sq ft | Demolition, disposal, site prep |
| Labor to install Trex deck | $4.50/sq ft | $7.50/sq ft | $11.00/sq ft | Fastening, flashing, finishing |
| Permits and inspections | $50 | $350 | $1,000 | Depends on locality and scope |
| Delivery and disposal | $75 | $200 | $500 | Tarps, debris removal, haul-away |
Trex Deck Replacement Cost: Typical Price Range by Project Size
Project size drives most of the price: 100–200 sq ft, 200–350 sq ft, or 350–500+ sq ft. In a 150–200 sq ft replacement, expect total costs around $6,000 to $12,000 on average. For 300–350 sq ft, typical ranges are $12,000 to $22,000, with higher-end upgrades pushing toward $25,000 or more. Costs include both materials and labor, and assume a standard residential backyard access and mid-grade Trex material. Assumptions: Midwest labor rates, standard Trex line, normal access, and no structural retrofit.
Major Cost Components in a Trex Deck Replacement
The quote splits into four key areas: materials, framing, labor, and extras. A compact view shows how each part contributes to the total. The table below presents representative ranges for a mid-size project using standard Trex decking and pressure-treated framing. Assumptions: 200 sq ft footprint, standard joist spacing, no in-floor lighting or complex stairs.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials – decking | $2.50/sq ft | $4.00/sq ft | $6.50/sq ft | Trex decking board price range |
| Framing lumber | $1.50/sq ft | $2.50/sq ft | $3.50/sq ft | Joists, rim boards, blocking |
| Labor for removal | $2.00/sq ft | $3.50/sq ft | $5.50/sq ft | Demolition and cleanup |
| Labor for installation | $4.50/sq ft | $7.50/sq ft | $11.00/sq ft | Decking, fasteners, flashing |
| Permits | $50 | $350 | $1,000 | Municipal review fees |
| Delivery/Disposal | $75 | $200 | $500 | Materials delivery, debris removal |
Key Variables That Change the Trex Deck Price
Size, slope, and stairs are the biggest price shifters. The exact square footage plus the number of stairs and the complexity of railing affect both materials and labor. A 2–3 step deck with simple lines will cost less than a multi-level design with curved railings or underdeck drainage. Regional labor rates can add or subtract several thousand dollars, and a change in Trex line (Value, Select, or Ultragrade) shifts board pricing by roughly 1.5x to 2.0x. Assumptions: standard grade Trex, mid-range railing, normal soil conditions.
Regional Variations That Impact Trex Deck Pricing
Coast, plains, and metro markets show meaningful spreads. In the Northeast and West Coast, expect higher labor and delivery charges, while the Southeast and Midwest often run lower. A typical 200 sq ft replacement could be $9,000–$14,000 in one region and $12,500–$18,000 in another. Permitting rules and disposal fees also vary by municipality. Assumptions: regional pricing reflects typical urban/suburban markets.
Material Choices Within the Trex Lineup and Their Price Impact
Material tier matters more than color in cost terms. The Trex family ranges from lower-cost decking boards to premium ultralow maintenance products. A standard Trex deck may run $2.50–$4.50 per sq ft for boards, while premium lines can reach $6–$7 per sq ft. For 200 sq ft, that’s roughly $500–$2,700 in board pricing alone, not counting joists, fasteners, or labor. Assumptions: 2–3 color options, standard grooved boards, hidden fasteners used where possible.
Extras That Add to the Final Trex Deck Price
Ask about essential add-ons early to avoid sticker shock. Underdeck drainage, railing upgrades, integrated lighting, and stairs with landings can each add $1,000–$4,000 or more. A simple upgrade to a full-coverage railing system and upgraded lighting may push a 200 sq ft project by $2,000–$5,000. Delivery, disposal, and permit costs can add another few hundred to a few thousand. Assumptions: standard LED rail lighting, mid-range railing posts.
How to Reduce the Trex Deck Replacement Price Without Sacrificing Quality
Target scope, timing, and material choices to trim costs. If the current deck is structurally sound, reuse framing where allowed and focus on decking removal and resurfacing rather than a full rebuild. Consider mid-range Trex boards instead of premium lines, plan for off-peak scheduling, and bundle services with a single contractor. Doing prep work yourself, such as clearing plants, can also reduce on-site labor. Assumptions: standard site access, no major structural repair.
Three Real-World Quote Scenarios for a 200 sq ft Trex Replacement
Concrete examples help anchor expectations. Scenario A: mid-range boards, standard framing, no extras — roughly $9,000–$12,000. Scenario B: mid-range boards plus basic railing and lighting — about $12,000–$16,000. Scenario C: premium Trex line with full railing, drainage, and two stairs — $18,000–$25,000+. Assumptions: 200 sq ft footprint, typical access, local permit rules apply.
Note: Always get multiple written quotes with a breakdown to compare apples-to-apples. Prices shown reflect typical U.S. markets and standard project conditions. Labor rates can vary by crew size, schedule, and region. Assumptions: standard 8–10 hour workdays, one crew, no weather delays.
