If you have shopped composite decking lately, you already know the spread is wider than it used to be. Trex decks cost ranges from $35 to $95 per square foot installed depending on the product line, the substructure, and how much your contractor is charging for labor in your zip code. The cheapest Trex Enhance Basics runs about $2.30 per linear foot in material; the top-tier Trex Signature pushes $7.50 per linear foot. Everything else falls in between, and the install labor on top often doubles the bill.

Installed Price Per Square Foot
For a basic 200 square foot deck using Trex Enhance Basics, expect $7,000 to $11,000 total installed in most US metros. The same deck in Trex Transcend runs $13,000 to $18,000. Stepping up to Trex Signature on a 400 square foot deck with railings, lighting, and a wraparound staircase can push past $40,000.
Why the spread? Labor varies by region from $35 to $75 per hour for a deck builder. A 200 square foot deck takes 60 to 90 hours including substructure, railings, and finish trim. Add a permit fee ($150 to $500 depending on jurisdiction) and possibly an architectural review for deck over 30 inches above grade.
Substructure Cost Breakdown
The pressure-treated lumber substructure (posts, beams, joists) is rarely counted in composite pricing but adds significant cost. For a typical 200 square foot deck:
- Footings: $400 to $1,200 (concrete piers or helical screws)
- Posts (6×6 PT lumber): $300 to $600
- Beams (2×10 PT, doubled): $400 to $700
- Joists (2×10 PT at 12 inch on center for composite): $700 to $1,100
- Ledger board with flashing: $200 to $400
- Hidden fasteners (Camo, Cortex, or Trex Hideaway): $250 to $450 per 200 sq ft
For premium builds, swap pressure-treated joists for Fortress Evolution steel framing ($8 to $12 per linear foot) or TimberTech Subframe. Steel adds $2,000 to $3,500 to a typical 200 square foot deck but doubles structural life to match the Trex warranty.
Railings Add Up Fast
Trex Transcend railings, Signature aluminum railings, or third-party Westbury aluminum railings all run $80 to $160 per linear foot installed. A 200 square foot deck with 40 feet of railing adds $3,200 to $6,400 to the project. Cable rail systems push pricing higher at $130 to $220 per linear foot but provide unobstructed views.
Pressure-treated wood handrails painted to match Trex composite reduce railing cost to $40 to $60 per linear foot but require repainting every 4 to 6 years. Most homeowners regret the savings within a decade.
Pricing by Deck Size
- 10 x 12 ft (120 sq ft): $4,200 to $11,400 installed
- 12 x 16 ft (192 sq ft): $6,700 to $18,200 installed
- 16 x 20 ft (320 sq ft): $11,200 to $30,400 installed
- 20 x 24 ft (480 sq ft): $16,800 to $45,600 installed
- Wraparound 600 sq ft: $21,000 to $57,000 installed
Add-On Costs That Surprise Homeowners
Several common add-ons are not included in baseline quotes:
- Stairs: $400 to $800 per 3-foot tread including stringers and risers
- Lighting: Trex DeckLighting kits add $400 to $1,500
- Pergola integration: $3,500 to $9,000 for an attached structure
- Skirting: $15 to $35 per linear foot of perimeter
- Built-in bench seating: $40 to $80 per linear foot
- Inset planters: $200 to $500 each
Labor Rate Variation by Region
The Northeast and West Coast typically charge $55 to $85 per hour for licensed deck contractors. The Midwest and Southeast average $40 to $65 per hour. Rural pricing can dip to $30 to $45 per hour with smaller crews, but availability is tight in peak season (April through August).
TrexPro Platinum certified installers typically charge a 15 to 25 percent premium over uncertified general contractors but carry the manufacturer’s 25-year labor warranty on top of the material warranty. For Trex decks cost on the higher product lines, the certification premium is worth it.
DIY Savings Versus Pro Install
A skilled DIY builder can save 40 to 55 percent of installed cost by sourcing materials directly from Home Depot, Lowe’s, or a Trex dealer like ABC Supply. A typical 200 square foot Trex Enhance deck costs about $3,500 to $5,000 in materials including all hardware. That said, structural mistakes (under-spec joists, missed flashing, insufficient footings) cost more to fix than the original savings.
For a first-time deck builder, hire out the framing and substructure (the structural risk zone) and DIY the deck board installation and railings. Hidden fasteners like Cortex or Camo make finishing close to foolproof.
Permits and Long-Term Cost
Most jurisdictions require permits for decks above 30 inches off the ground or larger than 200 square feet. Permit fees run $150 to $500 plus possible plan review. Skipping the permit risks fines and homeowner insurance issues if the deck fails. Build to IRC 2021 standards, get inspected, and the deck holds value at resale. Over a 30-year horizon, Trex decks cost less per year than pressure-treated lumber because there is no staining, sealing, or board replacement cycle.
Trex Versus TimberTech and Other Competitors
Trex commands roughly 40 percent of the US composite decking market, but TimberTech, Fiberon, and Deckorators all offer competitive products. TimberTech AZEK Vintage Collection runs about $5.50 to $7.50 per linear foot (similar to Trex Transcend) and uses PVC capping instead of polyethylene; it stays cooler underfoot in direct sun. Fiberon Concordia and Sanctuary lines undercut Trex Transcend by about 10 to 15 percent and offer comparable 25-year warranties.
Deckorators Voyage and Vault use mineral-based composite rather than wood-plastic composite, which reduces water absorption and weight. Pricing matches Trex Select. For a homeowner comparing options, get quotes for the same deck size in 2 to 3 brands; the structural cost is identical, so material price is the only true variable.
Resale and Return on Investment
According to Remodeling Magazine’s annual Cost vs Value report, composite deck additions consistently return 55 to 65 percent of cost at resale, slightly lower than wood deck additions (65 to 70 percent) due to higher install price. The trade-off is dramatically lower lifetime maintenance, which favors composite for homeowners staying 10+ years. For a flip or short-hold property, pressure-treated wood may make more financial sense.
