Custom Deck Builders in the Hamptons | Ipe, Composite & Automated Pergolas

The Materials Conversation Comes First

On the South Fork, a deck is rarely just a deck. It is the surface between the house and the pool, the stage for a summer of entertaining, and often a finish detail an architect has specified down to the fastener. So when we sit down with a Hamptons homeowner, we do not start with square footage. We start with the boards.

Long Island Deck Company, a Decks Unique company, has built custom decks on Long Island for 39 years, and the East End is where our material library gets used to its full depth. Two families of decking dominate our Hamptons work.

Ipe and Mahogany

For homeowners who want real hardwood, ipe is the benchmark: extraordinarily dense, tight-grained, and naturally resistant to the moisture and insects that punish lesser lumber. It takes on a deep, even tone when oiled, or weathers to a refined silver-gray if you let the salt air do its work. Mahogany offers a warmer, redder character with a classic estate feel suited to shingle-style and traditional architecture. Both ask for periodic cleaning and oiling to hold their color, and we will walk you through that maintenance rhythm honestly before you commit.

Top-of-the-Line Composite and PVC

Many East End clients split their time between the city and the beach, and the last thing they want is a deck that needs attention while they are away. Trex Signature and Transcend, TimberTech's premium lines, and Azek PVC deliver convincing wood grain with no upkeep beyond a rinse. PVC earns its place near pools and on damp, low-to-grade sites because it contains no wood fiber to feed moisture or mildew. As a Trex Platinum and TimberTech Pro certified builder, we offer a 10-year labor warranty on eligible Trex Signature and Transcend decks, on top of manufacturer fade-and-stain coverage running up to 50 years.

Engineered for Ocean Wind and Salt Air

A beautiful surface on a mediocre frame is a short-lived investment anywhere - and a fast-failing one near the Atlantic. Oceanfront and bayfront decks from Westhampton Beach to Montauk face wind, salt spray, and nor'easters that inland decks never see, so the structure underneath is specified accordingly.

We frame with KDAT lumber - pressure-treated, then kiln-dried after treatment - so the structure starts drier, stays straighter, and resists the twisting and shrinking ordinary framing goes through as it dries in the sun. Our KDAT framing carries a limited lifetime transferable warranty. On exposed sites, hurricane-rated connectors and hold-downs create a continuous load path from decking to footings, resisting uplift when storms push wind under elevated structures. Fasteners are stainless or high-quality ceramic-coated, because standard coatings corrode quickly in salt air. Joist tape, careful ledger flashing, and picture-framed borders complete the details no one photographs but everyone benefits from twenty years later.

Automated Louvered Pergolas: The Centerpiece of the Modern Hamptons Backyard

If one feature defines high-end East End outdoor living right now, it is the automated louvered pergola. Aluminum louvers rotate from a remote or phone app: open for full sun, angled for filtered light, closed tight to shed a passing shower so dinner continues uninterrupted. Some systems retract entirely, and rain sensors can close the roof automatically.

These structures solve the genuine South Fork problem of weather that turns on a dime - a bright afternoon, a sea breeze, then a squall off the ocean - without committing you to the permanent shade of a fixed roof. We design them as architecture, not accessories: matched to the lines of the house, integrated with low-voltage lighting and heaters for shoulder-season evenings, and engineered with wind ratings appropriate to exposed oceanfront sites. For a traditional look, we also build fixed timber pergolas in cedar and hardwood, proportioned to the house rather than ordered from a catalog. Because a pergola changes the loads on the deck below, we design the two together.

Cable Rail, Glass, and the View You Paid For

On a property overlooking the ocean, a bay, or open farm fields, the railing is the difference between a deck that frames the view and one that fences it off. Stainless cable rail keeps sightlines open with a crisp, nautical character. Glass panels disappear almost entirely while doubling as a windbreak - a real comfort on exposed bluff and dune-top sites. We handle the code requirements these systems carry, from post blocking and cable tension to height and opening limits near drop-offs, so the result is as safe as it is transparent.

Pool Surrounds Built for Bare Feet

Pools anchor most Hamptons backyards, and the decking around them works harder than any other surface. We design pool surrounds for comfort, traction, and drainage: lighter board colors that stay cooler in July sun, deeper-embossed textures that keep wet feet planted, consistent gapping and under-deck ventilation, and PVC or premium capped composite that does not mind a daily soaking. Two-tone borders outline walking paths, built-in benches keep towels off the wet deck, and low-glare step lighting makes evening swims safer without lighting up the neighborhood.

Working with Architects, Builders, and Estate Managers

A good share of our South Fork work arrives through professionals rather than homeowners directly. Architects bring us drawings that need a builder who can execute a detail as drawn - mitered borders, concealed fasteners, custom rail profiles - and flag structural realities early rather than mid-build. Estate managers need a contractor who shows up when scheduled, communicates in writing, and leaves the site clean, because the owner may not see the property until Memorial Day. We are comfortable in both arrangements, we are licensed and insured, and we handle permit drawings, applications, and inspections with the local building departments so paperwork never stalls the project.

Deck Resurfacing: New Life on Sound Framing

Plenty of East End decks have solid bones under a surface that has gone gray, splintered, or simply dated. When an inspection confirms the framing is sound, resurfacing - new decking and railings installed over the existing structure - delivers a dramatic transformation at a meaningful saving over full replacement. It is a popular path for newly purchased homes where the buyer inherits a sound deck in last decade's material and wants ipe or premium composite instead. If the frame does not deserve new decking, we will tell you, and show you exactly why.

Communities We Serve Across the Hamptons

We build across the full length of the South Fork, and each hamlet brings its own conditions.

• Hampton Bays sits between Shinnecock Bay and the Peconic, where bayfront breezes reward open cable rail and wind-rated pergola engineering.
• East Quogue pairs quiet wooded streets with Shinnecock bayfront exposure - a mix that calls for moisture-tolerant decking and corrosion-resistant hardware.
• Bridgehampton runs from farm fields to ocean dunes, with architecture that keeps both our mahogany and glass-rail details busy.
• East Hampton brings estate-scale projects where decks, pool surrounds, and pergolas are designed as one composition, often alongside an architect.
• Amagansett homes near the dunes face some of the saltiest air on the island, making ipe and PVC the materials we reach for first.
• Westhampton Beach, the western gateway, and neighboring Quogue mix village homes with barrier-beach exposure.
• Southampton and Water Mill carry some of the East End's deepest outdoor-living investment, from village lots to oceanfront estates.
• Sagaponack and Wainscott sit between farm fields and the Atlantic, where wide, low decks suit the open land.
• Sag Harbor and North Haven face the harbor and bay rather than the open ocean, favoring waterside decks with clear sightlines to the moorings.
• Montauk, at the island's exposed eastern tip, is the ultimate test of wind engineering - and the reason we specify the hardware we do.

Frequently Asked Questions

Do you build custom pergolas in Montauk, Amagansett, and East Quogue?

Yes - the full eastern stretch of the South Fork is within our regular service area. For exposed sites in Montauk and Amagansett we pay particular attention to wind ratings, anchoring, and the structural connection between pergola and deck, since coastal gusts there are stronger than anywhere else on Long Island. We build both automated louvered systems and traditional fixed timber pergolas, and we handle the local permitting.

What decking do you recommend in Sag Harbor?

Sag Harbor's harborfront and village settings suit two directions. For historic and traditional homes, mahogany or ipe delivers the authentic wood character the village is known for, weathering gracefully in the salt air. For owners who want zero seasonal upkeep, premium capped composite or Azek PVC provides a convincing wood look with nothing more than an occasional rinse. We bring samples of both to the property so you can judge them against the house in daylight.

Ipe or composite for an oceanfront home - which holds up better?

Both perform well by the ocean, but they age differently. Ipe is dense enough to resist salt air, moisture, and insects for decades; the trade-off is periodic oiling if you want to keep its brown tone rather than letting it silver. Top-line composite and PVC never need oiling and carry fade-and-stain warranties of 25 to 50 years, but the supporting cast matters most on the oceanfront: stainless fasteners, hurricane-rated connectors, and a KDAT frame - and we build that way regardless of surface. The decision comes down to look and maintenance appetite, not durability.

Do you install automated retractable pergolas in the Hamptons?

Yes. Automated louvered and retractable pergolas are one of our signature offerings across the Hamptons. Louvers adjust by remote or app, rain sensors can close the roof automatically, and we integrate lighting and heating for evenings that stretch into October. We engineer each unit for its wind exposure and design it together with the deck below it.

Do you handle deck repairs in the Hamptons?

Our schedule is built around full custom builds and resurfacing projects, so we take on repair work late in the season as the calendar allows. If the framing is sound but the surface is worn, resurfacing often beats patch repairs - we are glad to inspect and tell you which path makes sense.
