Long Island Service Areas: Where We Design & Build Custom Decks

Every part of Long Island asks something different of a deck. A canal-front lot in Freeport has to meet flood-zone elevation rules. A bluff in Miller Place takes the full force of Sound winds. An oceanfront home in Montauk needs engineering and materials a mid-island colonial never will. Building well here means knowing the difference - and we do.

Long Island Deck Company, a Decks Unique company, designs and builds custom decks, pergolas - including automated louvered systems - and deck resurfacing across Nassau, Suffolk, and the East End, all from our showroom in Commack. With over 39 years of deck-building experience and Trex Platinum and TimberTech Pro installer status, we bring the same craftsmanship to every town we serve. Below is the complete directory of the 19 regions we cover, organized by county. Find yours, then explore everything we build.

Nassau County

From the Queens line to the Suffolk border, Nassau packs an enormous range of homes into one county - bayfront villages, Sound-front estates, and the classic mid-island neighborhoods in between. Here's how we serve each part of it.

The Five Towns

The Five Towns sit on Nassau's southwest bayfront corner, where villages like Lawrence, Cedarhurst, Woodmere, Hewlett, and Atlantic Beach combine old trees, water views, and some of the most detail-conscious architectural review boards on Long Island. We design decks that respect each village's character and prepare drawings that hold up to careful review, so approvals don't stall your project.

Great Neck & Manhasset Peninsula

The peninsulas of Great Neck, Kings Point, Manhasset, Port Washington, and Sands Point are home to Sound-front estates and architect-driven renovations. We're comfortable working alongside architects and landscape designers, engineering decks and outdoor structures that match the scale of these properties and stand up to wind coming off Long Island Sound.

Roslyn & the North Shore Corridor

From Roslyn and East Hills through Glen Head, Sea Cliff, and the Brookvilles, the land rolls - wooded lots, slopes, and grade changes that a flat-lot deck design can't handle. This is multi-level deck territory: landings, wide stairs, and tiered platforms that follow the hill instead of fighting it.

Glen Cove, Oyster Bay & the Necks

Glen Cove, Oyster Bay, Locust Valley, and Bayville share historic harbors and homes that sit close to open water. Decks here need true exposed-water engineering - corrosion-resistant hardware, uplift protection, and framing that shrugs off salt air - and that's exactly how we build them.

Garden City & Central Nassau

Garden City, Mineola, Floral Park, Franklin Square, and Elmont are classic village Nassau, where incorporated-village permitting has its own rhythms and requirements. We design colonial-scale decks that suit these homes and guide the permit process with the local building department so it stays straightforward and low stress.

South Shore Nassau

Valley Stream, Rockville Centre, Oceanside, Baldwin, and Freeport stretch along Nassau's South Shore, where canal-front lots and flood-zone rules shape what you can build. We handle elevation requirements, footing and structural details, and materials that stand up to the brackish water just over the bulkhead.

Bellmore–Merrick & the Massapequas

Bellmore, Merrick, Wantagh, Seaford, and the Massapequas are family neighborhoods where the backyard works hard - pools, grills, kids, and company. Pool decks and full outdoor-living layouts are our specialty here, with splinter-resistant composite surfaces that handle wet feet all summer long.

Mid-Island: Hicksville to Syosset

Hicksville, Levittown, Bethpage, Plainview, and Syosset grew up in the postwar building boom, and many of their original backyards are overdue for a rethink. We transform these yards with right-sized decks that add real living space without overwhelming the lot - and most are built in just a day or two.

Suffolk County

Suffolk is home. Our showroom is in Commack, our crews are on Suffolk roads every morning, and we've been building here for decades - from the harbor villages of the North Shore to the canals of the Great South Bay.

Greater Huntington & the North Shore Harbors

Huntington, Northport, Cold Spring Harbor, Lloyd Harbor, and Dix Hills mix harbor villages with estate necks and deep wooded lots. It's some of the most varied deck-building terrain in Suffolk, and it's practically next door to us - our designers know these streets well.

Greater Smithtown & Kings Park

Smithtown, St. James, Nesconset, Kings Park, and Hauppauge are our home turf - our showroom sits at 119 Commack Road in Commack, right in the middle of it all. Stop in to walk across full-size deck displays, compare Trex and TimberTech boards side by side, and see railing systems and lighting demos in person.

Babylon Township & the South Shore

Babylon, West Babylon, Deer Park, Lindenhurst, and Amityville line the Great South Bay, where canal-front living is everyday life. Salt air and bay moisture are tough on a deck, so we build with stainless or coated fasteners, moisture-protected framing details, and decking that holds its color near the water.

Greater Islip & Bay Shore

Bay Shore, Brightwaters, Islip, Sayville, and Bayport are bay communities and ferry towns where the water sets the pace of summer. Decks here are launching pads for bay life, and we design them for sun, salt, and steady use from May through October.

Central Brookhaven: Ronkonkoma to Patchogue

Ronkonkoma, Centereach, Holbrook, Coram, and Patchogue are working-family Suffolk, and homeowners here want honest value: a deck that's built right, priced fairly, and ready for years of barbecues and pool seasons. That's exactly what we deliver, with financing available for qualified homeowners.

Three Village & Brookhaven's North Shore

Stony Brook, Setauket, Port Jefferson, Miller Place, and Rocky Point trace Suffolk's North Shore, where bluff lots and Sound views come with serious wind exposure. We engineer for it - deeper footings, hurricane-rated hardware, and bracing designed for decks that perch above the water.

The Moriches & Eastport

Center Moriches, East Moriches, Eastport, Mastic, and Shirley occupy the quiet bayfront stretch between Patchogue and the Hamptons. It's an easygoing corner of the South Shore where a well-built deck makes the most of the bay breezes - without Hamptons pricing.

The East End

Past Riverhead, Long Island splits into two forks with their own pace and their own building challenges - plus the beach communities of Fire Island. We cover all of it.

Riverhead & the Sound Shore

Riverhead, Calverton, Baiting Hollow, and Aquebogue have welcomed wave after wave of newer communities, and many homeowners here are planning their first real deck. We make that first project simple - clear designs, straightforward pricing, and guidance through any permitting along the way.

The North Fork

Jamesport, Mattituck, Cutchogue, Southold, and Greenport anchor Long Island wine country, where farmhouses and second homes look out over vineyards and bays. We work with second-home owners on schedules that fit their time out east, building decks that suit the North Fork's relaxed, rural character.

The Hamptons & South Fork

From Westhampton and Hampton Bays through Southampton, Sag Harbor, East Hampton, and Montauk, the South Fork demands the best - premium decking, oceanfront engineering, and shade structures that match the architecture. Our automated louvered pergolas are especially popular here, opening and closing at the touch of a button.

Fire Island & the Beach Communities

Ocean Beach, Fair Harbor, Saltaire, Kismet, and the Pines are car-free beach communities where the deck practically is the house - it's where everyone lives from Memorial Day until fall. Building here means planning ferries, barges, and material logistics, and we handle all of it.

Wherever You Are, We're Close By

Nineteen regions, one standard of work. Every project - whether it's a family pool deck in Wantagh or an oceanfront build in Amagansett - gets the same engineering care, from KDAT framing under the boards to a lifetime workmanship guarantee behind the whole thing. Contact us for a free design consultation, or call (631) 623-9300 or (516) 689-7800 and tell us where you live. We'll take it from there.
