Trex Decking: Costs, Pros & Cons, and Where to Buy in Raleigh (2026)

Last updated June 3, 2026

Trex composite decking typically runs, as of 2026, $45 to $70 per square foot installed including framing, with the broader composite range spanning $35 to $80 depending on the product line and how complex the build is. A 12-by-12-foot Trex deck runs roughly $6,500 to $10,000; a 300-square-foot deck about $10,500 to $21,000 all-in. It costs more than wood up front and earns that back over time in saved maintenance. Here's the honest breakdown before you decide.

How much does a Trex deck cost in Raleigh?

The installed figure most sources land on is $45 to $70 per square foot including framing, though the composite category as a whole spans $35 to $80 depending on the line you choose and your site. Boards alone run $5 to $16 per square foot, climbing from entry-level lines up to the premium tiers. The rest is labor, framing, railings, and stairs — and labor is a larger share for composite than for wood, because the material calls for precise assembly and special fasteners.

By project size, expect roughly:

  • 12' × 12' (144 sq ft): $6,500 to $10,000
  • 300 sq ft: $10,500 to $21,000 all-in, including framing, railings, and a basic stair run

Add-ons move the number: Trex-approved fasteners run about $1 to $2 per square foot, railing systems $40 to $70 per linear foot, and features like lighting, built-in seating, or multi-level designs add more. North Carolina building permits for decks vary by county, so factor that into a Wake County project.

Trex vs. wood: the cost comparison

At installation, Trex is the more expensive choice — there's no way around it. A composite deck addition averages $25,096 against $18,263 for a comparable wood deck, a roughly 27 percent premium, per the 2025 Zonda Cost vs. Value Report. The case for composite is the long view: over about 20 years, the gap typically narrows or closes because Trex needs no annual sanding, sealing, or restaining, and it lasts two to three times longer than wood before replacement. A composite deck addition also recoups an estimated 88.5 percent of its cost at resale.

So the honest framing is the same as with most premium building materials: if lowest upfront cost is the goal, wood wins; if you're staying put and want to stop maintaining a deck every year, composite usually wins over its lifetime.

Trex decking pros and cons

Pros

  • Low maintenance. No sealing, staining, or sanding — an occasional wash is the routine. This is the headline reason homeowners switch.
  • Durable and resistant. Resists splintering, rot, mold, and insect damage, and capped composite lines add an outer shell for better fade and weather resistance.
  • Long warranties. Trex's entry-level Enhance line carries a 25-year limited residential warranty plus a 25-year fade-and-stain warranty; higher lines extend further.
  • Strong resale and looks. Wood-grain textures and a range of colors, with the ~88.5% ROI noted above.

Cons (the parts worth knowing before you commit)

  • Higher upfront cost than wood — roughly 2 to 5 times the material cost, and higher labor because of the precise assembly and special fasteners.
  • Heat retention. In direct sun, composite — especially lower-end lines — can get noticeably hotter underfoot than wood. Worth weighing for a south-facing, unshaded Raleigh deck; premium lines mitigate this better.
  • It's not structural. Trex is the surface, not the skeleton — you still need a properly built wood or steel frame underneath, which is part of why install labor runs high.
  • Quality varies by tier. "Composite" spans entry-level to luxury; the cheapest line and the premium line perform differently, so compare by warranty length, not just price per foot.

Warranty — verify the current terms

Trex warranties run by product line — the entry-level Enhance line has carried a 25-year limited residential warranty plus a 25-year fade-and-stain warranty, with premium lines extending further. Warranty terms and product lineups change, so confirm the current coverage for your specific line directly with the manufacturer or your installer before you buy — treat any figure in a guide, including this one, as a starting point, not the final word.

Is Trex worth it in Raleigh?

For a homeowner planning to stay several years, Trex tends to pay off: the higher upfront cost is offset by near-zero maintenance, a long lifespan, and strong resale value — and the low-upkeep argument lands especially well in a humid climate where a wood deck demands constant attention. The cases against it are a tight upfront budget, a short ownership horizon, or a fully sun-exposed deck where heat retention matters and you'd want to spend up for a premium line. As always, the right answer depends on your situation, not the brand's reputation.

Where to buy Trex decking in Raleigh

Composite decking rewards a skilled installer — proper framing, fastening, and spacing are what prevent movement and warping over time, so it's not the best DIY candidate. Find local decking suppliers in the Raleigh decking supplier directory, and compare vetted deck builders in best home remodelers in Raleigh. Get at least three quotes, confirm each contractor's experience with composite specifically, and verify NC licensing and insurance.
