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.

Paul & Kim D.Massapequa · Trex Transcend Deck

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.

Angela R.Wantagh · Composite Deck

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.

Frank T.Commack · Deck + Patio Combo

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.

Lauren M.Garden City · Travertine Pool Deck

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.

Dan K.Smithtown · Mahogany Deck

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.

Common Questions

Before you call us.

A composite deck resurfacing service on Long Island typically costs 40–60% less than a full deck replacement. If your existing frame (joists, ledger board, posts) is structurally sound, we remove the old decking boards and install new composite decking — Trex Transcend, TimberTech Azek, or similar — on the existing frame. For a standard 300 sq ft Long Island deck, composite resurfacing runs $6,000–$11,000 depending on the composite brand chosen and whether railings need replacement. We do a free frame inspection first: we check the ledger connection, joist spacing, post footings, and beam condition before quoting. If we find structural issues, we quote repair options so you can decide. Composite deck resurfacing service on Long Island includes permit coordination in Nassau or Suffolk County, removal and disposal of old boards, and our 5-year workmanship warranty. Most resurfacing projects complete in 3–5 days after permit approval.

Yes — in nearly every Nassau and Suffolk municipality, attached decks over 30 inches off grade or any deck with a roof/patio attached require a building permit. We pull every permit ourselves, included in the quote. You never visit a town hall.

A wood deck on Long Island typically costs $8,500–$20,000 for a standard 12×16 or 16×20 pressure-treated deck, fully installed. Cedar runs $12,000–$18,000. Composite (Trex/Azek) runs $15,000–$30,000 for the same footprint. Long Island prices run 20–30% above national averages due to labor rates and permit costs. Request a free estimate for your specific site.

Yes. Nassau County requires building permits for any attached deck and most freestanding decks over 200 sq ft or 30 inches off grade. Nassau permit fees run $250–$800 depending on the municipality — Town of Hempstead, Town of Oyster Bay, and incorporated villages each set their own fees. We handle every filing and inspection; you never visit a building department.

Yes. Suffolk County municipalities require permits for attached decks and for freestanding decks over a certain size threshold. Suffolk permit fees run $150–$500 depending on town — Town of Huntington, Town of Babylon, Town of Islip, and Town of Smithtown each have their own requirements. We pull every permit in-house.

Pressure-treated pine is cheaper upfront — typically $8,500–$20,000 installed versus $15,000–$25,000 for Trex composite at the same size. But over a 15-year period, pressure-treated requires sealing every 2–3 years ($300–$600 per treatment) and often full replacement by year 20. Trex requires only an annual pressure wash. Most Long Island homeowners who plan to stay 10+ years find composite cheaper long-term.

A standard 300 sq ft composite deck takes 2–3 weeks from permit approval: 2–3 days demolition, 3–5 days framing and footings, 3–4 days decking and railings, 1 day final walk-through. Add 8–18 business days for permit approval (Nassau runs faster than Suffolk). We give a firm timeline before we start.

Yes — we work across all of Long Island. Nassau jobs include Garden City, Massapequa, Wantagh, Bethpage, Hicksville, Merrick, and Levittown. Suffolk jobs include Huntington, Smithtown, Commack, Bay Shore, Babylon, and Northport. Same crew, same warranty, same permit process.

For South Shore Long Island homes (Merrick, Bellmore, Wantagh, Seaford, Long Beach) and North Shore waterfront properties, Azek's 100% PVC construction holds up better against salt air and moisture. Azek absorbs zero water — Trex composite has a small moisture expansion factor that matters more in high-humidity, salt-air environments. For inland Nassau and Suffolk, Trex Transcend is excellent and slightly more budget-friendly.

Yes. If your deck frame is structurally sound (joists, ledger, posts are solid), we can resurface by removing the old boards and installing new composite decking on the existing frame. This typically costs 40–60% less than a full deck replacement. We do a free frame inspection to tell you which route makes more sense.

A 300 sq ft composite deck typically takes 2–3 weeks from permit approval: 2–3 days for demolition, 3–5 days for framing and footings, 3–4 days for decking and railings, and 1 day final walk-through. We give a firm schedule before we start.

All three are capped composite or PVC decking with 25-year fade and stain warranties. Trex (Enhance and Transcend lines) has the widest color range and our most common recommendation. TimberTech AZEK is 100% PVC — slightly lighter, slightly more expensive, best for salt-air coastal homes. Azek (same parent as TimberTech) has a premium multi-tonal finish. We install all three and match to your goals.

Yes — we build composite pool decks (Trex, TimberTech), travertine, and paver pool decks. For in-ground pools we coordinate with your pool contractor on coping, bond beam, and drainage. We also re-surface existing pool decks that are cracked or uneven.

Yes — deck + patio combos are one of our most common projects. Upper composite deck off the back door, lower paver or travertine patio extending into the yard. One crew, one permit cycle, one integrated design. It's almost always less expensive than doing them separately.

Composite boards carry 25-year fade and stain warranties from Trex and TimberTech. Our workmanship warranty is 5 years on every project. Mahogany and cedar decks come with our workmanship warranty plus the natural lifespan of the wood when finished properly. All in writing.

2026 Cost Guide

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.

Deck TypeSizeCost Range (Installed)
Pressure-treated pine12×16$8,500 – $14,000
Pressure-treated pine16×20$12,000 – $20,000

Prices reflect Nassau and Suffolk County averages including Town of Hempstead (11550, 11553), Town of Oyster Bay (11801, 11714), Town of Babylon (11702, 11704), and Town of Huntington (11743, 11746) permit fees. Actual pricing varies by site conditions — request a free estimate for an exact quote.

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.

Best for coastal / waterfront
Azek (TimberTech PVC)
12×16 installed (LI)$18k – $30k
Moisture absorptionZero — 100% PVC
Thermal expansionMinimal — handles direct sun well
Salt air resistanceExcellent
  • 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
Best value — most Long Island homes
Trex Transcend
12×16 installed (LI)$15k – $25k
Moisture absorptionMinimal — wood-fiber composite
Thermal expansionSmall factor, not an issue inland
Salt air resistanceGood — ideal for inland Nassau/Suffolk
  • 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
Azek vs TimberTech: They are the same product. TimberTech acquired the Azek brand — the Azek Vintage and Landmark collections and the TimberTech AZEK line are equivalent materials. Older quotes say “Azek,” newer ones say “TimberTech AZEK” — same thing. We are certified installers for both and will tell you honestly which one your site calls for.
Deck Resurfacing

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.

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.

Nassau County

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.

Suffolk County

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 Decking

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.
