The three brands that win 90% of Long Island composite decks
If you've asked three contractors for a composite deck quote on Long Island, you've heard three brand names: Trex, TimberTech, and Azek. That's not a coincidence — between them, they control the Northeast composite market, and for good reason. Each has been tested in our salt-air, freeze-thaw climate for 20+ years. The question isn't which brand is "best." It's which line within each brand fits your home, your budget, and how much sun exposure your deck gets.
We install all three because homeowners want choice. Here's how they actually compare on a real Long Island build.
At-a-glance comparison
| Feature | Trex Transcend | TimberTech AZEK Vintage | TimberTech PRO Reserve | Azek Harvest |
|---|---|---|---|---|
| Core material | Wood-plastic composite | 100% PVC (capped polymer) | Capped composite | 100% PVC |
| Warranty | 25-yr fade & stain | 50-yr fade & stain | 30-yr fade & stain | 30-yr fade & stain |
| Salt-spray rating | Excellent | Best-in-class | Excellent | Best-in-class |
| Heat retention | Moderate-high | Low (reflective capstock) | Moderate | Low |
| Cost per sq ft (installed, LI) | $34 - $42 | $58 - $72 | $42 - $52 | $48 - $62 |
| Color range | 14 colors | 12 premium colors | 9 colors | 8 colors |
| Best use case | Budget-conscious, moderate sun | Waterfront, premium home | Mid-range, shaded yards | Pool deck, hot climates |
Installed prices include framing, fasteners, and labor for a typical 350 sq ft single-level deck in Nassau. Waterfront projects and second-story decks run 15-25% higher.
Trex — the volume leader
Trex is the brand most Long Islanders already know. It's a wood-plastic composite (WPC) with a capped polymer surface, made in Virginia. The Transcend line is their flagship and handles our climate well — we've got 2014 Transcend decks in Massapequa and Wantagh that still look like the day they were installed.
Where Trex shines:
- Best price-to-performance ratio in the "nice composite" tier
- Color line includes warm wood-grain looks (Spiced Rum, Lava Rock, Tiki Torch) that pair well with cedar-sided homes
- Widest installer network — any composite-certified LI builder can work with it
- Strong residual resale value because buyers recognize the name
Where Trex stretches:
- The wood core absorbs slightly more heat than 100% PVC boards — noticeable on a south-facing deck in August
- Stain warranty is shorter than TimberTech's capstock-based warranty
- Not our first pick for direct oceanfront installs (Bayville, Atlantic Beach, Ocean Beach)
TimberTech — the premium option with two tiers
TimberTech splits their lineup into AZEK (100% PVC) and PRO (capped composite). This trips up homeowners, because TimberTech and Azek are the same parent company (AZEK Building Products), but they sell Azek-branded lines and TimberTech-branded lines side by side at most LI lumberyards.
TimberTech AZEK Vintage — the most premium board we regularly install. It's 100% PVC, so there's zero wood fiber to absorb moisture, warp, or harbor mold. The Alloy Armour capstock is genuinely reflective, which keeps surface temps 15-20°F cooler than wood-core composites on a 90°F day. The 50-year fade-and-stain warranty is the strongest in the industry.
We default to TimberTech AZEK Vintage for: waterfront homes, full-sun pool decks, and any client who's going to hold the home for 20+ years. The upfront premium pays back in lower surface heat, better salt resistance, and stronger warranty coverage.
TimberTech PRO Reserve — mid-tier capped composite. Think of it as "Trex Transcend plus" — a little better capstock coverage, a little lower heat retention, a slightly longer warranty. About 20-25% more than Trex.
Azek — the pool-deck specialist
Azek is the other half of the AZEK Building Products portfolio. The Harvest and Arbor collections are 100% PVC and, like TimberTech AZEK, run cooler underfoot than any WPC. Where Azek differentiates is in the hardscape-adjacent color palette — they've nailed the bluestone and limestone-look boards that blend seamlessly with a paver patio or travertine pool coping.
We recommend Azek when the deck and the patio need to visually read as one material system — a common situation on Long Island pool-deck expansions where homeowners want a composite surface near the house and travertine or bluestone by the water.
Our honest recommendation matrix
- Budget build, partial shade, 10-15 year horizon: Trex Transcend
- Premium build, full sun, long hold: TimberTech AZEK Vintage
- Pool deck adjacent to hardscape: Azek Harvest or Arbor
- Shaded North Shore wooded lot, mid-budget: TimberTech PRO Reserve
- Direct oceanfront, salt spray daily: TimberTech AZEK Vintage — nothing else holds up as well

Pictures on a website lie. Every composite looks different at 10 a.m. vs. 5 p.m., wet vs. dry, under full sun vs. under a pergola. We bring physical sample boards of all three brands to your estimate appointment so you can see them in your backyard, against your siding, in the light your deck will actually live in.
