Understanding Trex cost per square foot is essential for budgeting a composite deck project accurately. Trex dominates the composite decking market with three distinct product lines at different price points, and the gap between material cost and installed cost catches many homeowners off guard.
After building and consulting on hundreds of deck projects, we’ve compiled real-world pricing data for every Trex product line, including the hidden costs that add 30-50% to the sticker price of the boards themselves. Here’s what you’ll actually spend in 2026.
Trex Product Lines and Material Costs
Trex offers three product lines, each targeting a different budget and performance level. Here’s the Trex cost per square foot for materials only.
Trex Enhance (Entry Level) — $7 to $10 per square foot:
- Enhance Basics: $7-$8/sq ft. Scalloped (hollow) profile, lighter weight. Three color options. 25-year limited warranty. Trex’s most affordable board.
- Enhance Naturals: $8-$10/sq ft. Solid or scalloped profiles, more realistic wood grain patterns. Six color options. 25-year limited warranty with 25-year fade and stain warranty.
Trex Select (Mid-Range) — $9 to $12 per square foot:
- Solid profile boards with a natural wood-grain finish
- Five color options including popular saddle and pebble grey
- 25-year limited residential warranty, 25-year fade and stain warranty
- Better scratch and stain resistance than Enhance
Trex Transcend (Premium) — $12 to $16 per square foot:
- Transcend Lineage: $12-$14/sq ft. Latest generation with the most realistic wood appearance. Four luxury colors.
- Transcend: $13-$16/sq ft. Deep wood-grain pattern on both sides. Eight color options. Premium tropical hardwood aesthetics.
- 25-year limited residential warranty, 25-year fade and stain warranty, 50-year structural warranty
- Best scratch resistance and color fidelity in the Trex lineup
These prices are for the deck boards only — 1×6 or 2×6 grooved or square-edge boards sold by the linear foot or board foot at retailers. The actual per-square-foot cost depends on board width, waste factor, and regional pricing.
Installed Cost Per Square Foot
The installed Trex cost per square foot includes materials (decking boards, substructure, fasteners, hardware) and labor. This is the number that matters for your actual budget.
- Trex Enhance installed: $18 to $28 per square foot
- Trex Select installed: $22 to $32 per square foot
- Trex Transcend installed: $28 to $42 per square foot
Why is the installed cost 2-3 times the material cost? The board price is only one component. You also need a pressure-treated wood substructure (joists, beams, posts, ledger board), hidden fasteners, joist tape, concrete footings, and labor that typically runs $8-$15 per square foot depending on your market and deck complexity.
Labor cost breakdown:
- Basic ground-level rectangular deck: $8-$12/sq ft labor
- Elevated deck with stairs: $12-$18/sq ft labor
- Multi-level or complex deck with angles: $15-$25/sq ft labor
- Second-story deck with extensive framing: $18-$30/sq ft labor
Trex vs Wood Deck Costs
The initial cost comparison between Trex and wood favors wood. The long-term cost comparison almost always favors Trex.
Upfront material costs (per square foot):
- Pressure-treated pine: $3-$6
- Cedar: $6-$10
- Trex Enhance: $7-$10
- Redwood: $8-$14
- Trex Select: $9-$12
- Trex Transcend: $12-$16
- Ipe (Brazilian hardwood): $12-$20
20-year total cost comparison (materials + maintenance, 300 sq ft deck):
- Pressure-treated pine: $3,000 initial + $4,000-$6,000 maintenance (annual staining/sealing, board replacement) = $7,000-$9,000 total
- Trex Enhance: $6,000 initial + $200-$400 maintenance (occasional cleaning) = $6,200-$6,400 total
- Trex Transcend: $9,000 initial + $200-$400 maintenance = $9,200-$9,400 total
The math is clear: Trex Enhance costs less than pressure-treated wood over 20 years when you factor in ongoing maintenance. Premium Trex lines approach parity with wood but deliver a maintenance-free experience that many homeowners value highly.
Hidden Costs Beyond the Boards
Many homeowners budget only for decking boards and get blindsided by the additional expenses. Here are the costs beyond the Trex cost per square foot for the boards themselves.
Substructure (framing): $3-$7 per square foot of deck surface. Pressure-treated joists (2×8 or 2×10 at 12″ or 16″ on center), beams, posts, and ledger board. This cost is the same whether you use Trex or wood decking on top.
Hidden fasteners: $1.50-$3 per square foot. Trex recommends their proprietary hidden fastener systems (Trex Hideaway, Cortex plugs) for grooved-edge boards. Screws and clips aren’t cheap for composite decking.
Joist tape: $0.30-$0.50 per linear foot of joist. Trex Protect joist tape extends the life of your substructure by preventing moisture damage where the composite board contacts the wood joist.
Concrete footings: $75-$200 per footing. Most decks need 6-12 footings depending on size and local code requirements. Some jurisdictions require full poured footings below the frost line.
Permits: $100-$500 in most jurisdictions. Required for attached decks and any deck over a certain height (typically 30 inches above grade).
Old deck removal: $3-$8 per square foot if you’re replacing an existing deck. Disposal fees add $200-$600 depending on volume and local dump rates.
Stairs: $100-$200 per step installed, including stringers, treads, risers, and railing. A 4-step staircase runs $400-$800.
Railing, Lighting, and Accessory Costs
Trex offers a full ecosystem of accessories that add function and aesthetics to your deck — and cost.
Trex railing systems:
- Trex Select railing: $35-$55 per linear foot installed. Basic composite railing with square balusters.
- Trex Transcend railing: $45-$75 per linear foot installed. Premium profiles and color options.
- Trex Signature aluminum railing: $50-$80 per linear foot installed. Sleek aluminum with powder-coat finish.
- Cable or glass panel infill: $70-$150 per linear foot installed. Maximum view preservation.
For a 300 sq ft deck with 60 linear feet of railing, expect to add $2,100-$4,500 for composite railing or $4,200-$9,000 for premium aluminum or glass options.
Trex lighting: $15-$40 per fixture for post cap lights, riser lights, and deck rail lights. A typical deck lighting package (8-12 fixtures + transformer) costs $300-$800 installed.
Fascia boards: $3-$5 per linear foot. Used to cover exposed joist ends for a finished look. A 300 sq ft deck typically needs 40-60 linear feet of fascia ($120-$300).
Total Cost by Deck Size
Here’s what complete Trex deck projects cost at different sizes, using mid-range Trex Select with standard composite railing, basic stairs, and professional installation.
- Small deck (100 sq ft / 10×10): $3,500-$5,500 total
- Medium deck (200 sq ft / 10×20): $6,000-$9,000 total
- Standard deck (300 sq ft / 12×25): $8,500-$13,000 total
- Large deck (500 sq ft / 16×32): $14,000-$22,000 total
- Premium large deck (500 sq ft, Transcend + aluminum rail): $20,000-$32,000 total
These estimates include decking, substructure, railing (3 sides), one set of stairs (4 steps), fasteners, footings, permits, and labor. Geographic location swings these numbers by 20-30% — expect higher costs in coastal metro areas and lower costs in the Midwest and Southeast.
Factors That Affect Your Price
Several variables push the actual Trex cost per square foot above or below average estimates.
Deck height: Ground-level decks need minimal substructure — a simple frame on deck blocks or low-profile footings. Second-story decks require tall posts, heavy beams, cross-bracing, and more complex engineering, adding $5-$15 per square foot to the project.
Deck shape: Rectangular decks are the most efficient to build. Angles, curves, multi-levels, and octagonal bump-outs increase material waste (15-25% vs 10% for rectangles) and labor time significantly.
Site access: Crews need to get materials and equipment to the build site. Easy backyard access keeps costs down. Tight side yards, steep lots, or fenced areas that require hand-carrying materials can add $500-$2,000 to the project.
Local labor rates: Deck-building labor varies from $8/sq ft in low-cost markets to $25+/sq ft in expensive metro areas. This single factor can make a bigger difference than your product selection.
Season: Deck building peaks from April through October in most markets. Booking during the off-season (November through March) can save 10-20% on labor if your contractor stays busy year-round.
Ways to Save on Trex Decking
Practical strategies to reduce your total Trex cost per square foot without compromising quality.
Choose Enhance over Transcend: The Enhance Naturals line delivers a great-looking deck at 40-50% less than Transcend. For most homeowners, the aesthetic difference doesn’t justify the price premium. Enhance carries the same core warranty protection.
Keep the design simple: A rectangular deck with standard 90-degree corners minimizes waste and labor. Every angle cut increases waste, and curves require custom fabrication. A clean rectangle maximizes usable space per dollar.
Do your own demo: If replacing an existing deck, tearing out the old one yourself saves $1,000-$3,000 in labor. Rent a dumpster ($300-$500) and spend a weekend on demolition before the crew arrives.
Compare contractor quotes: Get at least three detailed quotes. Specify the exact Trex product line and color so you’re comparing apples to apples. Ask for itemized quotes that separate materials from labor.
Buy materials yourself: Some homeowners save 10-15% by purchasing Trex materials directly from a retailer during sales and having the contractor provide labor only. Check with your contractor first — some prefer to supply materials for warranty and convenience reasons.
Consider Trex Enhance Basics for low-visibility areas: Use premium Transcend on the main deck surface and Basics on stair treads, fascia, or areas hidden by furniture. The color difference is minimal but the cost savings are significant.
Frequently Asked Questions
How much does a 12×12 Trex deck cost?
A 12×12 (144 sq ft) Trex deck costs $3,500-$6,500 fully installed with Enhance, $4,500-$8,000 with Select, or $5,500-$10,000 with Transcend. These estimates include substructure, fasteners, and basic railing on three sides but not stairs or permits. Add $400-$800 for a standard 4-step staircase.
Is Trex decking worth the cost over wood?
For most homeowners, yes. The higher upfront cost is offset by near-zero maintenance over the deck’s life. No annual staining, sealing, or board replacement saves $200-$500 per year compared to pressure-treated wood. If you value your time and want a consistently good-looking deck without ongoing work, Trex pays for itself within 8-12 years.
How long does Trex decking last?
Trex decking carries a 25-year limited residential warranty (50-year structural warranty on Transcend). In practice, well-installed Trex decking lasts 30-50 years. The composite material resists rot, insects, and moisture damage that destroys wood decks. The substructure (pressure-treated framing) is typically the limiting factor, lasting 15-25 years before needing attention.
Does Trex add value to a home?
Deck additions typically recoup 65-75% of their cost at resale, and composite decking like Trex can improve that return because buyers recognize the low-maintenance benefit. A well-built Trex deck is a selling feature in most markets, especially for buyers who don’t want exterior maintenance projects. The exact ROI depends on your local market and how the deck integrates with the home’s overall design.
Can I install Trex decking myself?
The decking boards themselves are DIY-friendly — Trex provides detailed installation guides and the boards cut, drill, and fasten with standard tools. The challenge is the substructure. Building a structurally sound, code-compliant deck frame requires carpentry skills, knowledge of local building codes, and proper engineering. Many homeowners hire a contractor for the frame and install the Trex boards themselves to save on labor.
