Trex Decking Cost: 2026 Composite Board & Line Tier Pricing
Trex Decking Cost: 2026 Composite Board & Line Tier Pricing
Trex composite decking costs average $16,000 ($9,600–$24,000) in 2026. Compare Enhance, Select, and Transcend lines, and calculate costs with our deck tool.
1. Project Overview & Pricing Benchmarks
Building a composite deck with Trex decking is one of the premier outdoor living investments for American homeowners. Manufactured from 95% recycled plastic film and reclaimed wood sawdust, Trex boards never require sanding, staining, or toxic chemical sealers. They eliminate the perennial splintering and rot associated with pressure-treated lumber while carrying 25 to 50-year manufacturer warranties.
In 2026, the national average turnkey cost to construct an elevated, single-level 320-square-foot (16x20 ft) Trex composite deck is $16,000 (averaging $50.00 per square foot fully installed with pressure-treated framing, footings, and certified builder labor). Depending on your product line (Enhance, Select, or Transcend), deck height, and railings, turnkey projects span between $9,600 and $24,000.
2026 National Pricing Benchmarks: What Trex Really Costs
Across verified contractor databases—including Fixr, HomeGuide, and Angi—Trex decking projects break down into four distinct material tiers:
| Trex Collection Tier (16×20 ft / 320 sq ft) | Installed Cost Range | Installed Sq Ft Rate |
|---|---|---|
| Tier 1: Trex Enhance (Scalloped Basics) | $9,600 – $14,400 | $30 – $45 / sq ft |
| Tier 2: Trex Select (Solid Edge Workhorse) | $12,500 – $17,500 | $39 – $55 / sq ft [Avg: $16,000] |
| Tier 3: Trex Transcend (Flagship Luxury) | $15,500 – $22,500 | $48 – $70 / sq ft |
| Tier 4: Transcend Lineage (Cooling Tech) | $17,500 – $25,000+ | $55 – $78+ / sq ft |
The Trex Product Lineup: Enhance vs. Select vs. Transcend
Choosing between Trex’s three core product families aligns your budget with durability expectations:
- Trex Enhance (Basics & Naturals): Trex’s value collection features a scalloped underside that reduces weight and material costs ($5.00 to $7.00 per square foot for boards). Backed by a 25-Year Warranty, it delivers natural wood grain aesthetics at an affordable price, though outer stair steps require solid fascia wraps to conceal the scalloped flutes.
- Trex Select (Solid-Core Workhorse): Occupying the balanced mid-tier ($7.00 to $9.50 per square foot for boards), Select offers a solid-core profile with enhanced rigidity, authentic graining, and a 35-Year Warranty.
- Trex Transcend (Flagship Luxury & Tropicals): Wrapped in a three-sided protective shell ($10.00 to $13.50 per square foot), Transcend resists heavy food grease, sharp pet claws, and UV fading. Its multi-tonal streaking replicates exotic hardwoods like teak and ipe, backed by a 50-Year Warranty.
- Trex Transcend Lineage (Heat-Mitigating Technology): Engineered with solar-reflective pigments ($12.00 to $15.50 per square foot), Lineage stays noticeably cooler under bare summer feet, making it the top choice for sunny pool decks.
10-Year Lifecycle Cost: Trex Composite vs. Pressure-Treated Wood
While pressure-treated pine costs less upfront ($25 to $35 per square foot), ongoing maintenance quickly erases the difference:
| Ownership Expense Item | Pressure-Treated Pine (320 sq ft) | Trex Select Composite (320 sq ft) |
|---|---|---|
| Initial Construction Cost | $9,000 | $16,000 |
| Annual Deep Cleaning | $1,200 ($120/yr spring wash) | $300 (Occasional soap rinse) |
| Sanding & Staining (Every 2 Yrs) | $4,800 ($960/cycle × 5 cycles) | $0 (Never stained) |
| Board Warping & Splinter Repairs | $1,500 (Board replacement) | $0 (Backed by warranty) |
| 10-Year Cumulative Cost | $16,500 | $16,300 (Break-even) |
| 15-Year Projected Total | $20,500+ | $16,600 (Saves $3,900+) |
By year 10, total expenditure balances; by year 15, composite decking delivers thousands of dollars in cumulative savings without splintering or warping.
Substructure Engineering: Joist Spacing and Moisture Barriers
Because composite boards are flexible thermoplastic blends, certified builders follow strict framing guidelines:
- 16-Inch Joist Spacing: Perpendicular boards require joists spaced at maximum 16 inches on-center (or 12 inches for diagonals) to prevent sagging.
- Trex Protect Butyl Tape: Applying waterproof tape ($0.70–$1.20/sq ft) protects framing from moisture rot.
- Trex Hideaway Fasteners: Hidden clips maintain a uniform 3/16-inch drainage gap and a screw-free surface.

DIY vs. Professional Contracting: Avoiding Thermal Expansion Errors
Homeowners can save 30% to 40% ($4,800 to $6,400) on labor by building DIY. However, composite decking expands with temperature; failing to maintain 1/8-inch butt-joint gaps causes buckling. Improper ledger flashing also risks foundation water leaks. For elevated decks and warranty protection, hiring an NADRA-certified deck builder is strongly advised.

DIY vs. Hiring a Professional Contractor
Savings after purchasing materials, tools, and disposal fees.
Composite decking expands along its length with temperature swings. Failing to leave the required 1/8" to 3/16" thermal butt-joint gaps causes board buckling in summer heat. Installing boards on joists spaced wider than 16" on-center (or 12" for diagonal patterns) causes spongy sagging. Ledger boards fastened without flashing cause structural home wall rot. We strongly recommend NADRA-certified deck contractors for new builds.

Frequently Asked Questions
Detailed answers to the most common homeowner pricing and planning questions.
What is the average cost to build a 16x20 Trex deck in 2026? ↓
Building a standard 16x20 foot (320 square feet) Trex composite deck in 2026 costs $16,000 on average ($50.00 per square foot fully installed). Turnkey project pricing spans from $9,600 for entry-level Trex Enhance scalloped boards on a basic rectangular frame up to $24,000 or more for premium Trex Transcend Lineage decking with composite railings, embedded LED stair riser lighting, and concrete frost-line piers.
How much does Trex decking cost per square foot installed? ↓
On average, professional Trex deck installation ranges from $30 to $75 per square foot, including pressure-treated substructure framing, footings, Trex composite boards, and certified carpenter labor. Trex Enhance costs $28 to $45 per square foot installed, mid-tier Trex Select ranges from $38 to $55 per square foot, and flagship Trex Transcend spans $48 to $70+ per square foot installed.
Is Trex composite decking cheaper than wood over 10 to 15 years? ↓
Yes. While pressure-treated wood decking has a lower initial construction cost ($20 to $35 per square foot), it requires power washing, sanding, and staining or sealing every 1 to 2 years, costing $800 to $1,500 per cycle. Over a 10 to 15 year ownership period, wood maintenance expenses exceed $8,000, making Trex composite substantially more economical over its full 25 to 50 year lifespan.
What is the difference between Trex Enhance, Select, and Transcend? ↓
Trex Enhance is a lightweight scalloped-back board backed by a 25-year warranty, designed as an economical alternative to wood. Trex Select is a solid-core profile with a 35-year warranty offering greater rigidity. Trex Transcend is a premium solid-core board wrapped in a three-sided protective shell with deeply embossed tropical wood streaking, extreme scratch resistance, and a 50-year warranty.
How long does a Trex composite deck last? ↓
Trex composite decking boards last 25 to 50 years with minimal maintenance (occasional washing with soapy water). Trex boards are manufactured from 95% recycled plastic film and reclaimed industrial wood sawdust, making them impervious to rot, splintering, wood-boring insects, and mold decay.
