Custom Deck Builders in South Shore Nassau, NY

Drive the streets south of Freeport's Nautical Mile and you can see what a backyard means on the Western Bays: canal after canal lined with bulkheads and boat lifts, where the deck often takes the place of a lawn entirely. A few miles north, in East Meadow or the village of Hempstead, a deck has a completely different job - privacy from close neighbors, shade in an open yard, and enough room for the whole family on a Saturday afternoon. Two very different customers, often within the same town, and we build for both.

Long Island Deck Company, a Decks Unique company, brings more than 39 years of deck-building experience to South Shore Nassau from our showroom at 119 Commack Road in Commack. This page covers how we approach the bay communities from Valley Stream to Freeport - and the inland neighborhoods behind them.

Canal-Front and Bay-Front Decks: Freeport, Baldwin Harbor, and the Island Park Shore

Canal lots tend to be long and narrow, and the yard ends at a bulkhead instead of a fence. That changes the whole design conversation. The deck usually wants to run toward the water, with sightlines kept open to the canal and the boat. Cable and aluminum railing systems are popular here for exactly that reason - they meet code without walling off the view. Layouts often need to work around dock access, davits, and the path from the back door to the boat, so we plan stairs and landings as part of the route, not as an afterthought.

Salt Air Sets the Hardware Spec

Everything on a bay-front or canal-front deck lives in salt-heavy air, and the parts that fail first are usually the parts you can't see. We spec stainless steel or high-quality ceramic-coated fasteners, hidden fastener systems built for coastal exposure, and corrosion-resistant structural connectors. For the walking surface, capped composite and PVC boards handle constant moisture and salt spray far better than bare wood - it's why so much of our waterfront work uses Trex, TimberTech, or Azek PVC. Our composite deck building page covers those product lines in depth. Underneath, our KDAT framing - kiln-dried after treatment, so it starts drier and more stable than standard treated lumber - gives the structure itself a better chance against the moisture cycle of life on the water.

Elevating a Deck in a Flood Zone

Plenty of homes along the canals in Freeport, Baldwin Harbor, and Island Park have been raised since the last round of major coastal flooding, and many more sit in mapped flood zones. A deck on one of these homes is a different engineering problem: the first floor may now be many feet above grade, so the deck has to be designed at that height, with engineered posts and footings, uplift-rated hardware for open-water wind exposure, and stair runs broken up with landings so the climb feels natural rather than fire-escape steep. Permits and inspections are often part of these projects, and we guide that process from drawings through final sign-off so you're not left interpreting flood-zone requirements on your own.

If you found us in the past through our pages for Island Park, Barnum Island, Bay Park, or East Rockaway, those pages now live here. Island Park and neighboring Barnum Island sit on some of the lowest ground in Nassau County, so elevation and salt-rated hardware drive nearly every deck we design there. Bay Park, the waterfront hamlet beside East Rockaway, shares the same conditions. And East Rockaway itself, at the head of the bay, mixes older waterfront blocks with quiet inland streets - we build for both sides of the village.

Inland South Shore Nassau: A Different Yard, a Different Deck

Step inland past Sunrise Highway and the design brief changes. In Hempstead, East Meadow, Uniondale, and Roosevelt, nobody is fighting salt spray - the challenges are close property lines, open sun, and yards that need to work hard for busy families. Privacy screens and pergolas earn their keep here. East Meadow's ranches and split-levels, many with generous yards near Eisenhower Park, suit wide single-level decks with built-in seating and room for a grill station. Hempstead's housing stock runs from prewar homes to newer construction, and we design each deck around the actual house - door heights, window lines, and how the family moves between kitchen and yard.

Roosevelt and Uniondale homeowners who bookmarked our old pages for those communities will land here now - nothing about our coverage has changed. Both communities are full of solid mid-century homes whose backyards deserve better than a cracked concrete patio, and we're regularly working in both.

Communities We Serve in South Shore Nassau

• Freeport - the canal grid south of the Nautical Mile is some of the most distinctive deck territory on Long Island, and elevation rules much of it.
• Baldwin - from inland streets down through Baldwin Harbor, where the lots narrow toward the water and the hardware spec changes with them.
• Oceanside - a big hamlet with both canal-front pockets and classic inland family blocks, so we build both kinds of deck here.
• Rockville Centre - established homes and mature trees, where decks tend toward traditional lines, quality railings, and careful integration with landscaping.
• Lynbrook - compact village lots that reward smart layouts: picture-framed borders, built-in benches, and stairs placed to save yard space.
• Valley Stream - at the Queens line, with tighter lots where a well-planned deck effectively adds a room to the house.
• Hempstead - the village at the center of it all, where we handle everything from straightforward pressure-treated decks to full composite builds.
• East Meadow - wide suburban yards that can carry larger decks, pergolas, and outdoor dining layouts without feeling crowded.

We also build throughout Malverne and West Hempstead, the quieter villages tucked between Valley Stream and Hempstead - same crews, same materials, same process.

Pergolas and Louvered Shade for South Shore Yards

Shade matters on both halves of this area, for opposite reasons. On the water, a pergola tempers afternoon glare coming off the canal without blocking the breeze. Inland, it turns a wide-open, full-sun yard into a space you can actually sit in at 2 p.m. in July. We build traditional fixed pergolas as well as automated louvered pergolas with rotating roof blades - open them for airflow, close them when the sun is high or a shower moves through. On bay-front installations we pay particular attention to anchoring and corrosion-resistant hardware, because a shade structure catches wind the way a sail does. See our pergola and outdoor structure page for the full range.

Deck Resurfacing: Keep the Frame, Replace the Surface

A lot of South Shore decks built in the 1990s and 2000s have the same profile: tired, splintering boards on top of framing that's still structurally sound. In those cases, resurfacing - new composite or PVC decking and new railings installed over the existing structure - delivers what looks and feels like a new deck for considerably less than a full rebuild. The honest part of the process is the framing inspection. Near the water we look hard at corroded fasteners, ledger connections, and post bases, because salt air attacks the structure from the hardware out. If the frame passes, we resurface with confidence. If it doesn't, we'll tell you plainly and price the rebuild instead - we don't put new boards over a structure we wouldn't stand behind.

Materials, Warranties, and the Commack Showroom

As Trex Platinum and TimberTech Pro certified installers, we work across both manufacturers' full lines, plus Azek PVC for maximum moisture resistance and natural wood - cedar, mahogany, pressure-treated - for homeowners who want the real thing and accept the upkeep, which is heavier in salt air. Trex fade-and-stain warranties run up to 50 years depending on the line, and TimberTech coverage generally ranges from 25 to 50 years. Beneath the surface, our KDAT framing carries a limited lifetime transferable warranty, and Decks Unique is the only decking company on Long Island offering it. Every project is backed by our lifetime workmanship guarantee, and financing is available for qualified homeowners.

The fastest way to make material decisions is to stand on the boards. Our showroom at 119 Commack Road in Commack has full-size deck displays, railing systems, and lighting demos - bring photos of your yard and sit down with a designer. Homeowners from Rockville Centre and Oceanside make the drive regularly; it tends to be the visit where the whole project clicks.

Frequently Asked Questions

Do you have deck installers in Hempstead?

Yes. Hempstead village and the surrounding communities are squarely inside our regular service area, and our crews are on the South Shore constantly. Design consultations happen at your home or at our Commack showroom, and once construction starts, most straightforward decks are completed in just 1–2 days.

How should I compare decking companies in Hempstead?

Look past the website and compare four things: manufacturer certifications (we hold Trex Platinum and TimberTech Pro status), labor coverage (we provide a lifetime workmanship guarantee, plus a 10-year Trex labor guarantee on Signature and Transcend projects), what goes underneath the boards (our KDAT framing carries a limited lifetime transferable warranty), and verified reviews. Any company can quote a price; the differences show up in what's backing it.

Can you build custom decks in Valley Stream on a smaller lot?

Absolutely - compact lots are where custom design matters most. In Valley Stream we frequently work with tighter side yards and property-line setbacks, using space-saving stair placement, built-in benches instead of freestanding furniture, and picture-framed borders that make a modest footprint feel finished. A well-designed 200-square-foot deck often outperforms a poorly planned one twice its size.

What does elevating a deck in a flood zone involve?

The deck is engineered to meet the home's raised first-floor height, which means deeper engineered footings, uplift-rated structural hardware for wind exposure, corrosion-resistant fasteners, and stair runs designed with landings so the descent feels comfortable. Permits and inspections are typically part of these projects, and we manage that process from drawings through final sign-off.

Do you build pergolas in South Hempstead?

Yes - we build both traditional fixed pergolas and automated louvered pergolas throughout South Hempstead and the neighboring villages, mounted over new decks, existing decks, or patios. The louvered systems are popular there because the rotating blades let you tune sun and airflow through the day instead of committing to fixed shade.
