Trex Decking on Long Island: Cost, Pros & What Contractors Charge

Trex Product Lines Explained for Long Island Buyers

Trex is the most recognized composite decking brand on Long Island and nationally. When most homeowners say they want a 'composite deck,' they often mean Trex by default — it's become somewhat generic, like 'Kleenex' for tissues. But Trex offers multiple distinct product lines at very different price points, and choosing the right one matters for Long Island's climate and your budget.

Trex Select is the entry-level line, made from 95% recycled materials. It's a solid, affordable composite that handles moisture and won't rot, but it has less protection against fading and staining than premium lines. For a sheltered deck in a low-humidity setting, Trex Select performs well. On Long Island's South Shore, near pools, or in high-traffic entertaining decks, it's not the ideal choice — the lack of full capping means the cut edges are exposed to moisture.

Trex Enhance is the mid-range option and a popular choice for Long Island homeowners who want composite durability without going to the top of the price range. Enhance Naturals and Enhance Basics both feature four-sided capping (the board is completely enclosed in a protective shell), which dramatically improves performance in wet conditions. The color selection is good, and the warranty is solid for this price tier.

Trex Transcend is the flagship line and the most commonly specified product by Long Island contractors for quality builds. Transcend features the most realistic wood grain textures, the deepest color palettes (including rich tropical-inspired tones), and Trex's strongest warranty — 25 years for fade and stain. For pools, waterfront homes in communities like Massapequa, Merrick, and Bay Shore, and homeowners who want a premium outdoor space, Transcend is typically worth the extra cost.

What Contractors Charge to Install Trex on Long Island

Trex installation costs on Long Island in 2026 typically break down as follows, all-in including materials, labor, fasteners, trim, and permit costs:

Trex Select: $18–$26 per square foot installed. A 400 sq ft deck runs approximately $7,200–$10,400 in materials plus $6,000–$8,000 in labor, totaling $13,000–$18,000 before extras like railings and stairs.

Trex Enhance: $22–$32 per square foot installed. A 400 sq ft deck typically runs $18,000–$24,000 all-in with standard railings.

Trex Transcend: $28–$42 per square foot installed. The same 400 sq ft deck runs $22,000–$32,000 with standard composite railings. Premium railing systems (cable, glass, or custom aluminum) add $3,000–$8,000.

Note that substructure (the framing under the deck) is typically pressure-treated lumber regardless of the decking material chosen. Some homeowners opt for aluminum or composite framing for maximum longevity — this adds $3,000–$8,000 to the project but eliminates the most moisture-vulnerable component of the deck. For waterfront properties or pool decks on Long Island, composite substructure is worth considering.

When comparing quotes from Long Island contractors, make sure each quote specifies the exact Trex product line, the railing system, whether permits are included, and the warranty terms the contractor offers on labor. The cheapest Trex quote often uses Select framing with Transcend boards — always read the spec sheet in full.
