Custom Decks, Pergolas & Resurfacing in Greater Islip & Bay Shore, NY

Where the Bay Sets the Tone

Greater Islip starts at the water. On a summer morning, the ferry docks in Bay Shore and Sayville are already busy - coolers, bikes, and beach chairs headed across the Great South Bay to Fire Island - and the neighborhoods behind them run on the same rhythm. Homes near the bay live with salt air, steady southwest breezes, and long afternoon light off the water. Down here, a deck isn't an add-on. It's the room where most of the summer actually happens.

Long Island Deck Company, a Decks Unique company, has been designing and building custom decks across Suffolk County for over 39 years. From our showroom at 119 Commack Road in Commack, we serve every corner of Islip Township - from the canal streets of Brightwaters to the newer, sunnier yards of Central Islip and Brentwood - with Trex, TimberTech, Azek/PVC, and natural wood decks built on our signature KDAT substructure. This page is our hub for the bay communities and the hamlets inland, organized the way the township itself is: starting at the shoreline and working north.

The Waterfront Tier: Ferry Towns, Canal Streets, and Bayfront Yards

The southern band of the township is where the water does the talking. Bay Shore is the busiest ferry gateway to Fire Island, with housing that runs from stately older homes near Main Street to tidy capes south of Montauk Highway - decks here get heavy entertaining use and need surfaces that shrug off humidity and foot traffic. Next door, Brightwaters is defined by its canals and village character; we design decks there around tighter lot lines and sight lines to the water, often with low-profile cable railings so nothing blocks the view.

West Islip anchors the township's western edge near the Robert Moses Causeway approach, where backyards catch real wind off the bay and uplift-rated hardware earns its keep. The hamlet of Islip - the community that gave the whole town its name - mixes classic South Shore homes with bay-adjacent streets, and East Islip wraps around the approach to Heckscher State Park, where mature trees and established yards call for decks that fit into a landscape rather than dominate it.

Great River deserves its own word. Set along the Connetquot River with deep, wooded lots, it's one of the township's quietest corners - and if you found us through our previous Great River page, this is now the home for that coverage. Nothing about the service has changed: same crews, same materials, same attention to riverfront moisture and shade conditions.

Continuing east, Oakdale shares the Connetquot's wooded riverfront feel, while Sayville and West Sayville carry the township's maritime heritage - Sayville runs its own ferries to the Fire Island communities, and its downtown keeps that working-harbor character. At the township's eastern edge, Bayport offers quiet bayfront streets where a well-proportioned deck and a louvered pergola can turn a backyard into the best seat on the South Shore.

Moving Inland: Central Islip, Brentwood, Bohemia & Islandia

North of Sunrise Highway the bay influence fades, lots open up, and the design questions change - less about salt air, more about full sun and family-scale entertaining. Central Islip has plenty of newer construction with wide, open backyards, which is exactly where shade structures and built-in seating pay off most. Brentwood, one of Long Island's largest hamlets, is full of hardworking family homes where a durable composite deck becomes the gathering spot for three generations at once. Bohemia, near Long Island MacArthur Airport, blends residential streets with light industry, and its homeowners tend to value low-maintenance materials that look sharp without weekend upkeep.

Islip Terrace, the compact hamlet between East Islip and Central Islip, was previously covered on its own page; that coverage now lives here, and we build there as actively as ever - its modest lot sizes are a great match for smart, space-efficient deck design.

The same goes for Islandia, the small village at the Long Island Expressway crossroads: our former Islandia page now points here, and homeowners there get the identical service, materials, and warranties as every bay community to the south.

Materials Built for Salt Air and South Shore Summers

Close to the Great South Bay, material choice is not cosmetic - it's structural strategy. Capped composites from Trex and TimberTech resist the fading, staining, and mildew that humid bay air accelerates, with fade-and-stain warranties running roughly 25 to 50 years depending on the line. Full PVC boards are the go-to for pool surrounds and homes closest to the water, since they handle constant moisture and stay cooler underfoot. For homeowners who love real wood, cedar, mahogany, and pressure-treated lumber all remain on the table - we'll just be honest about the sealing and staining schedule that South Shore humidity demands.

What sits under the boards matters even more here. We frame with KDAT lumber - kiln-dried after treatment - whenever we can, because it arrives at a stable moisture level instead of drying out (and twisting) in your backyard. It comes pre-stained a clean brown, looks finished from below on raised decks, and carries a limited lifetime transferable warranty. We're the only decking company on Long Island offering this upgraded framing, and in a region where the air itself is damp half the year, it's the difference between a deck that stays tight and one that slowly works itself loose.

Pergolas: Shade That Works With the Breeze

Bay-community backyards get two things in abundance: sun and wind. A pergola manages both. We build everything from classic wood-and-fiberglass pergolas to automated louvered pergolas whose roof panels rotate at the touch of a button - open for breeze, closed when an afternoon storm rolls in off the bay. On waterfront properties in Bayport or Brightwaters, a pergola frames the view without blocking it; on the wide, treeless lots common in Central Islip and Brentwood, it creates the shade the yard never had. Retractable and motorized options mean the structure adapts to the day instead of the other way around.

Deck Resurfacing: New Surface, Sound Bones

Plenty of homes in the older waterfront hamlets - Islip, Sayville, West Islip - have decks with perfectly solid framing under a tired, splintering surface. If the structure checks out, full demolition is a waste of money. Our resurfacing service strips the old boards and railings and installs new Trex, TimberTech, or PVC decking over the existing frame, often transforming the deck in a fraction of the time and cost of a rebuild. We inspect the framing honestly first: if it's compromised, we'll tell you, and if it's sound, you get what amounts to a brand-new deck on the bones you already own.

A Short Drive North to Our Commack Showroom

Material decisions get much easier when you can walk on full-size displays instead of squinting at samples. Our showroom at 119 Commack Road, Commack, NY 11725 is a straightforward drive up the Sagtikos from anywhere in Islip Township, and it's stocked with Trex and TimberTech boards, railing systems, lighting demos, and KDAT framing you can see and touch. Sit down with a designer, bring photos of your yard, and leave with a real plan. Call (631) 623-9300 or (516) 689-7800, or request a free estimate online and we'll come to you.

Frequently Asked Questions

What does deck installation in Bay Shore involve, especially near the water?

It starts with a site visit, because bay-adjacent properties have specific needs: footings set below the frost line in sandier soils, stainless or coated fasteners that stand up to salt air, and hardware rated for wind uplift. From there we design around how you'll actually use the deck, handle Town of Islip permit guidance when it's required, and complete most installations in just 1–2 days once construction begins.

Do you have custom deck builders serving East Islip and Central Islip?

Yes - the same design-build crews cover the entire township. The projects just look different: East Islip yards tend to be established, with mature trees and existing landscaping to design around, while Central Islip lots are often newer and more open, which shifts the conversation toward shade structures and railing styles. Either way, the consultation and estimate are free.

Can you build pergolas in Central Islip?

Absolutely, and it's one of the places they make the most sense - many Central Islip backyards get full sun all day. We install traditional pergolas as well as automated louvered models with rotating roof panels, so you can dial in shade in summer and let light through in spring and fall. They can be built over a new deck, an existing deck, or a patio.

Do you handle deck repair in Islip?

Honestly: our schedule is built around full deck construction and resurfacing, so we take on repair projects late in the season, when the build calendar opens up. If your framing is sound but the surface is failing, resurfacing is usually a smarter investment than piecemeal repairs anyway - you get an entirely new deck surface with modern materials instead of patches on old boards.

Which decking holds up best close to the Great South Bay?

Full PVC and capped composite boards from Trex and TimberTech are the strongest performers in constant salt air and humidity, with fade-and-stain warranties ranging from roughly 25 to 50 years by product line. Underneath, KDAT framing adds stability that standard wet pressure-treated lumber can't match. Wood decking is still an option near the water - it just requires a committed maintenance routine, and we'll spell that out before you choose.
