Use the Deck Cost Estimator 📞 Call (757) 676-0863A fully installed Trex deck typically costs $40–$80 per square foot, including the substructure, boards, basic railing, standard stairs, and labor. For a common mid-size deck, most homeowners land somewhere around $8,000–$25,000. The Trex boards themselves run roughly $9–$16 per square foot for material alone — but material is only part of a finished deck’s cost. Where you land depends on size, product line, railing, height, stairs, and site conditions.
Trex Decking Cost Per Square Foot
It helps to separate two very different “per square foot” numbers, because confusing them is where most online cost estimates go wrong:
Material only (boards)
Just the Trex boards — no framing, railing, or labor — generally run $9–$16 per square foot, depending on the product line. This is the number you’ll see on a retailer shelf, and it’s not what your finished deck costs.
Fully installed
A complete, professionally built Trex deck — substructure, fasteners, boards, railing, stairs, labor, and permit — typically runs $40–$80 per square foot installed. Simple, low, ground-level decks sit toward the lower end; elevated decks, premium board lines, and complex layouts push toward the higher end. Most standard residential projects land in the $55–$70 per square foot range installed.
Trex Deck Cost by Size
The most useful way to picture your budget is by deck size. The ranges below are planning estimates for a fully installed Trex deck — substructure, boards, basic railing, and standard stairs — at roughly $45–$75 per square foot. Your actual number depends on the factors further down this page.
| Deck Size | Square Feet | Estimated Installed Cost |
|---|---|---|
| 10 x 10 | 100 sq ft | $4,500 – $7,500 |
| 12 x 12 | 144 sq ft | $6,500 – $10,800 |
| 12 x 16 | 192 sq ft | $8,600 – $14,400 |
| 12 x 20 | 240 sq ft | $10,800 – $18,000 |
| 16 x 16 | 256 sq ft | $11,500 – $19,200 |
| 16 x 20 | 320 sq ft | $14,400 – $24,000 |
| 20 x 20 | 400 sq ft | $18,000 – $30,000 |
Planning estimates only. Elevated decks, premium board lines, multi-level designs, and added features (lighting, built-in seating, complex railings) can move a project above these ranges.

Trex sells several tiers, and the line you choose is one of the biggest levers on cost. From most accessible to premium:
Trex Enhance
The most accessible Trex line — clean colors, strong value, and the same low-maintenance core. A popular choice for budget-conscious builds.
$ — most accessible
Trex Transcend
The flagship line — deep, fade-resistant colors and premium textures with the strongest warranties.
$$$ — premium
Trex Signature
Trex’s top-tier line, with the most realistic wood-grain looks and the highest material cost.
$$$$ — top tier
Moving from Enhance to Transcend or Signature mostly affects the material portion of your cost. The substructure, labor, railing, and stairs stay similar — so the line you pick changes the total less dramatically than people expect. We help homeowners weigh the upgrade against the budget. For a deeper material comparison, see our Trex vs. TimberTech guide and our decking materials guide.
What Drives the Cost of a Trex Deck?
Two decks of the same square footage can differ by thousands. These are the factors that move your number:
- Deck size — the biggest single driver.
- Product line — Enhance vs. Transcend vs. Signature.
- Height & elevation — elevated decks need more substructure and labor.
- Railing system — composite, aluminum, or cable railings vary widely.
- Stairs — number of steps and landings adds cost.
- Substructure — footings, framing, and whether existing framing can be reused.
- Site conditions — slope, drainage, access, and demolition of an old deck.
- Add-ons — lighting, built-in seating, skirting, and pergolas.
- Permits — required in most areas; coastal and flood-zone rules can add cost.
- Labor & region — local rates and crew experience.
Is Trex Worth the Cost?
Trex costs more upfront than pressure-treated wood — but the comparison isn’t just the install price. A wood deck needs sanding, staining, and sealing every year or two, plus board replacement as it ages. Over 15–25 years, that ongoing maintenance and repair often closes much of the gap. Trex needs only occasional cleaning, resists fading and rot, and carries a long warranty.

Trex Deck Cost in Hampton Roads, VA
Local conditions matter. Here in Hampton Roads and Coastal Virginia, salt air, humidity, and flood-zone requirements affect how a deck is built — corrosion-resistant hardware, proper drainage, and in flood zones, elevated framing that adds to cost. Those are exactly the details that make composite a strong fit and a professional build worth it.

Trex Decking Cost FAQs
How much does Trex decking cost per square foot?
Trex boards alone run roughly $9–$16 per square foot. A fully installed Trex deck — substructure, boards, railing, stairs, and labor — typically costs $40–$80 per square foot, with most standard projects around $55–$70 per square foot installed.
How much does a 20×20 Trex deck cost?
A 20×20 Trex deck is 400 square feet and typically runs about $18,000–$30,000 fully installed, depending on the product line, railing, stairs, height, and site conditions.
How much does a 12×16 Trex deck cost?
A 12×16 Trex deck is 192 square feet and typically runs about $8,600–$14,400 fully installed, depending on materials and features.
Is Trex cheaper than a wood deck?
No — Trex costs more upfront than pressure-treated wood. But wood requires ongoing staining, sealing, and repairs, while Trex needs only occasional cleaning. Over 15–25 years, the lower maintenance often offsets much of the higher upfront cost.
Does the Trex product line change the price a lot?
It mainly affects the material portion. Moving from Enhance to Transcend or Signature raises board cost, but the substructure, labor, railing, and stairs stay similar — so the total changes less than many homeowners expect.
What’s the best way to get an accurate Trex deck price?
Use a deck cost estimator for a planning range, then get a professional on-site estimate. Site conditions, height, and local code (especially in coastal and flood zones) affect the final number in ways a calculator can’t fully capture.
