Get the Deck You’ve Always Wanted at a Price You Can Afford
Moriches Bay is the quiet stretch of the South Shore - calmer water than the Great South Bay to its west, none of the crowds of the Hamptons to its east. The hamlets that line it are small, the streets often end at the water, and the homes range from weathered bayfront cottages handed down through families to year-round houses where the deck is simply part of daily life. Long Island Deck Company, a Decks Unique company with over 39 years of building experience, designs and builds decks for exactly these properties: outdoor spaces that stand up to salt air, nor'easters, and long summer seasons without demanding a Hamptons budget.
Whether you're on the water in East Moriches or inland in Manorville where the Pine Barrens begin, you get the same crews, the same engineering, and the same lifetime workmanship guarantee. Most decks are completed in just 1–2 days once construction starts, and when a permit is required, we guide the process from drawings to final sign-off.
Our work in this corridor runs roughly from the Carmans River east to the Southampton town line - the stretch most of Long Island only drives through on the way to the East End. We think it deserves better.
Value-conscious waterfront work is its own discipline. The bay doesn't care what you spent, so the engineering can't be where you economize - footings below frost depth, hurricane-rated connections on exposed lots, and stainless steel or ceramic-coated fasteners that shrug off salt air are non-negotiable. Where there's real room to tune cost is the surface, and we'll lay the honest options side by side.
Trex and TimberTech composites span a wide price range: Trex Enhance and Select deliver fade-and-stain resistance at approachable prices, while Transcend and Signature offer premium color and grain. For decks right on the bay, full PVC handles constant moisture better than anything else we install. As Trex Platinum and TimberTech Pro certified composite deck builders, we can also pass along extended labor coverage on qualifying Trex projects. And for the bayfront cottage that should look like a bayfront cottage, pressure-treated, cedar, or mahogany keeps the traditional character - we'll be straight with you about the upkeep wood demands in this climate.
Under every surface we offer KDAT framing: lumber kiln-dried after treatment, so it starts dry and stable instead of shrinking and twisting as it cures in place, and pre-stained brown so the underside of an elevated bayfront deck looks finished from day one. Decks Unique is the only decking company on Long Island offering it, and it carries a limited lifetime transferable warranty - a real selling point if your home ever changes hands.

Shade on Moriches Bay is complicated: the afternoon sun comes off the water hard, but a fixed roof blocks the breeze that makes the shoreline bearable in August. A pergola splits the difference, and an automated louvered pergola settles the argument entirely - open the louvers for airflow, close them when the sun peaks or a shower blows through. We build traditional wood and low-maintenance aluminum pergolas and outdoor structures as part of a new deck or as freestanding additions, anchored properly for the wind that comes with open-water exposure.
Plenty of decks around the bay have gray, splintered boards over framing that's still perfectly sound. If that's yours, resurfacing - new composite, PVC, or wood decking and railings over the existing structure - delivers what looks and feels like a new deck for a fraction of full replacement. We inspect the substructure first and tell you plainly whether it qualifies. For value-conscious bayfront owners, this is often the single smartest dollar in outdoor work.
Pricing depends on the surface material, railing style, stairs, elevation, and extras like lighting or a pergola - not just square footage. Much of our work here is value-driven, so we're comfortable designing to a number: an Enhance-and-KDAT build and a Transcend showpiece are both legitimate projects. Financing is available for qualified homeowners, and every estimate starts with a free visit to your property.

Yes - Trex and TimberTech composite and PVC decking are the most requested materials we install around Moriches Bay. For homes close to the water in East Moriches, we typically recommend capped composite or full PVC with stainless or ceramic-coated fasteners, because salt air is hard on standard hardware. We're Trex Platinum and TimberTech Pro certified installers, and fade-and-stain warranties on these boards run roughly 25 to 50 years depending on the line.
We're honest about this: our build schedule is dedicated to full deck construction and resurfacing through the heart of the season, so we take on repair projects late in the season, once the year's builds are wrapping up. That said, if your deck boards are failing but the framing is sound, the project may actually be a resurfacing candidate rather than a repair - and resurfacing we can schedule much sooner. Call and describe what you're seeing, and we'll tell you which it is.
Yes, and the two illustrate our range. In Mastic Beach, the work is usually compact and weather-smart - modest footprints, salt-tolerant materials, and detailing that handles proximity to the water. In Manorville, larger lots open the door to multi-zone decks, freestanding pergolas, and bigger entertaining layouts. Both get the same KDAT framing option, the same crews, and the same lifetime workmanship guarantee.
Waterfront lots can come with conditions that inland properties don't have, and larger or elevated decks may require permits and inspections in any case. We handle the process with the local building department - drawings, submittals, and sign-off - so you're not navigating it alone. We'll flag anything about your specific lot during the free site visit, before design decisions get locked in.
It varies with material, railing, stairs, and height, so we won't quote blind - but this is one of the areas where we do our most value-conscious work, and we're glad to design to a budget. Entry-level Trex lines or pressure-treated decking over upgraded KDAT framing put a durable, warrantied deck within reach of most homeowners, and financing is available for qualified buyers. The accurate number comes from a free measure-up at your home.
Every project begins with a free visit to your property - that's where wind exposure, soil, sight lines, and budget get real. When you're ready to compare boards and railings in person, our showroom at 119 Commack Road in Commack has full-size deck displays an easy drive west on Sunrise Highway or the LIE. Call (631) 623-9300 or (516) 689-7800, or request your free quote online, and let's build something worthy of the quiet side of the South Shore.
