Vinny's team built the Trex deck we'd been talking about for ten years. Walked every plank, got the permit through Massapequa in a week, and finished on schedule. Neighbors keep coming over to look.
We had three estimates. Long Island Deck Co. was the only one with real drawings and real references in Wantagh. The composite deck they built is the nicest on our block. Crew was spotless.
They tore out our 20-year-old pressure-treated deck and rebuilt with TimberTech Azek plus an EP Henry paver patio underneath. One crew, one permit cycle. Whole backyard transformed in three weeks.
Our pool deck was cracking and uneven. Vinny recommended travertine instead of the concrete everyone else pitched. It looks incredible and stays cool under bare feet. Worth every penny.
I've had contractors ghost me before. Long Island Deck Co. is different — Rob returns every call the same day, Vinny shows up when he says, and the final walkthrough caught things I never would have noticed.
Built a full outdoor kitchen with patio, composite decking, and bar seating. They coordinated the gas line, the electrician, and the stone mason. I made two decisions. They handled everything else.

Adding a Wood Deck: Cost Guide for Long Island 2026
Long Island deck costs run 20–30% higher than national averages due to labor rates and local permit requirements. Nassau County building permits ($250–$800) and Suffolk County permits ($150–$500) are required for any deck attached to a home. Prices below are fully installed — demolition, footings, framing, surface, railings, and permits included.

Azek vs Trex Decking on Long Island — Which Is Better?
Both carry 25-year fade and stain warranties, but they are built differently — and those differences matter for Long Island homes near the water.
- South Shore (Merrick, Bellmore, Wantagh, Long Beach)
- North Shore waterfront (Cold Spring Harbor, Northport)
- Pools with salt chlorination
- Homes within half-mile of ocean or bay
- Inland Nassau suburbs (Massapequa, Levittown, Hicksville)
- Inland Suffolk (Commack, Smithtown, Dix Hills)
- Best color range — Havana Gold, Tiki Torch, Island Mist
- Trex Pro Platinum warranty — backed directly by Trex
Composite Deck Resurfacing Service on Long Island
If your deck frame is solid but the boards are faded, cracked, or warped, composite deck resurfacing is the most cost-effective upgrade on Long Island. We remove the existing decking, inspect every joist and beam, replace any compromised framing, and install new composite boards on your existing structure.
Resurfacing typically costs 40–60% less than a full deck replacement. A 300 sq ft composite resurfacing job in Nassau or Suffolk County runs $6,000–$14,000 depending on material choice (Trex, Azek, or TimberTech) and frame condition. Most jobs take 3–5 days.
We also handle composite deck replacement — full demo of both the boards and the frame, new footings, new pressure-treated framing, new composite surface. This is the right call when footings have heaved, the ledger connection is compromised, or the existing frame doesn't meet current code. Deck replacement on Long Island runs $15,000–$35,000 for a standard 300–400 sq ft project.
Both resurfacing and replacement include permits. Nassau and Suffolk building departments require permits for structural deck work — we handle every filing.
| Factor | Resurfacing | Full Replacement |
|---|---|---|
| Frame condition | Solid joists, no rot, no heave | Compromised frame, failed footings |
| Cost (300 sq ft) | $6,000 – $14,000 | $15,000 – $35,000 |
| Timeline | 3 – 5 days | 10 – 18 days (incl. permit) |
| Materials | New composite boards on existing frame | New frame + composite deck surface |
| Best for | Boards worn, frame structurally sound | Frame past 20 years, ledger issues, code upgrade needed |
| Permit required | Yes (Nassau + Suffolk) | Yes (Nassau + Suffolk) |
Free Frame Inspection
We inspect your existing frame before quoting. If the frame is solid, resurfacing saves 40–60%. If it needs replacement, we tell you upfront — not after demo.
Deck builders across Nassau County.
Nassau County is our home turf. Our shop is in Wantagh (11793) and we build decks from Garden City (11530) and Mineola (11501) in the north to Long Beach (11561) and Island Park (11558) on the south shore. The most common deck projects in Nassau are composite deck replacements on 1950s and 1960s homes in Levittown (11756), Hicksville (11801), Massapequa (11758), and Bethpage (11714) — homes where the original pressure-treated deck has hit 20+ years and the frame needs full replacement.
Nassau County permit timelines run 8–14 business days depending on the municipality. Town of Hempstead, Town of North Hempstead, and Town of Oyster Bay each have different building department requirements — we handle every filing and inspection. Villages like Garden City, Rockville Centre (11570), and Floral Park (11001) have their own building departments with additional overlay requirements. We navigate all of them.
South shore Nassau homes — Merrick (11566), Bellmore (11710), Seaford (11783), and Wantagh — deal with salt air from the Great South Bay. We spec TimberTech AZEK or Trex Transcend with stainless fasteners for these homes. North shore Nassau — Manhasset (11030), Great Neck (11021), Port Washington (11050), and Roslyn (11576) — typically wants premium materials and more complex multi-level designs.
Deck builders across Suffolk County.
Suffolk County deck projects tend to be larger — bigger lots, more multi-level designs, and more pool deck integrations. Our busiest Suffolk markets are Huntington (11743), Dix Hills (11746), Commack (11725), Smithtown (11787), Northport (11768), Kings Park (11754), and Bay Shore (11706). Suffolk permits run 10–18 business days through the Town of Huntington, Town of Smithtown, Town of Babylon, and Town of Islip building departments.
Coastal Suffolk homes along the north shore — Cold Spring Harbor (11724), Centerport (11721), and Northport — face Long Island Sound salt exposure. South shore Suffolk — Babylon (11702), Lindenhurst (11757), West Islip (11795), and Copiague (11726) — gets Great South Bay wind and salt spray. Both corridors benefit from 100% PVC decking (TimberTech AZEK) and marine-grade stainless hardware.
Pool deck projects dominate in Suffolk's larger-lot towns like Dix Hills, Melville (11747), East Northport (11731), and Hauppauge (11788). We coordinate directly with pool contractors on coping, bond beam height, and drainage — the coordination alone prevents the most common pool-deck failure on Long Island.
Trex Deck Installation on Long Island
Trex is the most-installed composite decking material on Long Island, and for good reason. Trex Transcend and Trex Select use a wood-polymer composite that resists fading, staining, and mold — the three issues that end the life of pressure-treated decks on Long Island faster than anything else. We are Trex Pro Platinum certified, the highest installer tier Trex awards, which means every job comes with a 25-year fade and stain warranty backed directly by Trex — not just us.
Trex deck installation cost on Long Island runs $15,000–$26,000 for a standard 12×16 deck, and $22,000–$42,000 for a 16×20 deck with premium railings. These numbers include demo of the existing deck (if any), new pressure-treated framing, Trex Transcend or Select decking, and permits for both Nassau and Suffolk County. Material alone runs $8–$14 per linear foot for Trex Transcend, $5–$9 for Trex Select.
Trex Transcend vs Trex Select on Long Island: Transcend is the flagship line — deeper embossed grain, more colors (Havana Gold, Tiki Torch, and Island Mist are popular on Long Island), and a thicker cap layer for better scratch resistance. Select is the value tier — clean, consistent appearance, white or pebble grey, and a lower price point. For homes with pool exposure, salt air, or heavy entertaining use, we spec Transcend. For standard backyard decks in Nassau County suburbs, Select holds up beautifully.
Trex deck resurfacing vs full Trex replacement: If your existing deck frame is in solid condition — joists plumb, no rot, footings stable — Trex resurfacing costs 40–60% less than a full build. We strip the old boards and install Trex directly onto the existing frame. Frame inspection is free and included in every estimate. We won't sell you a replacement when resurfacing is the honest answer.
| Trex Product | 12×16 Deck (LI installed) | Warranty | Best For |
|---|---|---|---|
| Trex Select | $12,500 – $19,000 | 25-yr fade/stain | Budget-conscious Nassau/Suffolk projects |
| Trex Enhance Naturals | $13,500 – $20,500 | 25-yr fade/stain | Realistic wood grain at mid-price |
| Trex Transcend | $15,000 – $26,000 | 25-yr fade/stain | Coastal homes, heavy-use entertaining decks |
| Trex Lineage | $17,000 – $28,000 | 50-yr limited | Premium installs, high-end renovations |
| Trex Select (resurfacing only) | $6,500 – $11,000 | 25-yr fade/stain | Sound existing frame, boards-only replacement |
