Custom Deck Builders in Greater Smithtown, NY - Our Home Turf

Follow the Nissequogue River down from Long Island Sound and you pass through some of the most settled, tree-shaded neighborhoods in Suffolk County - Kings Park, San Remo, Smithtown, the Village of the Branch, St. James. These are not blank-slate subdivisions. The oaks and maples had a head start of decades, the lots run larger than most of Long Island's, and plenty of the homes have already lived through a deck or two. Building well here means designing around what a property has become - not what an empty survey says it could be.

That kind of design work happens to be our specialty, and this area is literally our home turf. Long Island Deck Company, a Decks Unique company, works out of a showroom at 119 Commack Road in Commack - inside the township itself. When a homeowner in Nesconset or Hauppauge calls us, they are not hiring a contractor who needs directions. They are hiring the custom deck builder down the road.

A Deck Should Be Designed Around the Property, Not Dropped On It

On a brand-new lot, deck design is mostly geometry. In Greater Smithtown, three other questions usually decide whether a deck succeeds - what the trees are doing, what hardscape is already there, and what you see when you look out from the house. Every design conversation here starts with those three.

Start With the Trees

A mature canopy is the single best feature most Smithtown-area yards have, and the most common thing a bad deck design wastes. Before we draw anything, we map how shade moves across your yard: which corner stays cool for July dinners, where the morning sun lands, where leaves and pollen will collect. That mapping decides where the dining zone goes and where a pergola earns its keep. It also drives material choice - in heavily shaded, slower-drying yards near the river valley, we often steer homeowners toward PVC decking, which resists moisture and mildew best. And when a great oak stands exactly where the deck wants to be, we would rather frame around it or shift the footprint than cut it down.

Respect the Hardscape That Came First

Long-established homes here rarely have empty back yards. There is usually a patio from a previous owner, a pool and its surround, brick walkways, maybe a retaining wall holding back a grade change. A new deck has to negotiate with all of it - a low platform that steps cleanly down onto existing pavers so the two read as one space, or a transition landing that finally fixes the awkward drop between the kitchen door and a patio poured in 1985. We design around what is staying, so the finished deck looks like the plan all along, not the newest layer of a yard assembled in pieces.

Sight Lines and the Long View

Larger lots change the math on railings and orientation. If your property backs up to woods or the slopes of the Nissequogue valley, the view is worth protecting - we will suggest cable rail or slim-profile composite railing that keeps it open, and angle seating toward the best of it. Where neighbors sit closer, in the denser blocks of Commack or Hauppauge, the thinking runs in reverse: privacy screens, pergola placement, and planter walls that make the deck feel enclosed without feeling boxed in. Either way, we design from the chair you will actually sit in, not just from the plot plan.

The Second-Deck Conversation

Many of our Greater Smithtown projects replace an existing deck. The upside: you already know what your first deck got wrong. Too small for the table. Stairs in the wrong spot. A frame that twisted and loosened after a few winters. The second (or third) deck is the one you design with that knowledge - and build with better bones.

Those bones are where we differ from most builders. We frame with KDAT lumber - pressure-treated wood that is kiln-dried after treatment, so it arrives stable instead of drying, shrinking, and twisting on your property. The result is a flatter, tighter frame that holds fasteners better, and ours carries a limited lifetime transferable warranty. On the surface, we install Trex and TimberTech composite, Azek PVC, and natural wood, backed by manufacturer fade-and-stain warranties that run up to 50 years on the premium lines - plus our own lifetime workmanship guarantee and, as a Trex Platinum installer, a 10-year labor warranty on eligible Trex Signature and Transcend decks. If the first deck lasted fifteen years, this one is designed not to repeat the experiment.

Deck Resurfacing Across Smithtown Township

Not every tired deck needs to come down. If the framing underneath is sound - properly footed, dry, and solidly attached to the house - we can remove the worn decking and railings and install a new surface over the existing structure. Resurfacing is a strong option in established neighborhoods like Kings Park and Nesconset, where decks from the 1990s and 2000s often have decent frames under weathered boards. We inspect the structure first and tell you plainly whether it can carry another twenty years or whether resurfacing would be money wasted. When the frame passes, you get what looks and feels like a new composite or PVC deck at a meaningfully lower cost than a full rebuild.

Pergolas - From Cedar Classics to Automated Louvered Roofs

Shade is a design decision in this area, not an accessory, and pergolas are how we fine-tune it. A fixed pergola defines an outdoor dining room and softens harsh mid-afternoon sun. A retractable-canopy pergola lets you slide fabric panels open on a perfect June day and closed during an August heat wave. At the top of the range are automated louvered pergolas: motorized aluminum roofs whose slats rotate at the touch of a remote or phone app - open for full sun, angled for filtered light, fully closed to shed a passing shower. For homeowners who entertain on a schedule the weather refuses to respect, they are the closest thing to a roof you can turn off. See our pergola and outdoor structure work for the full range.

The Communities We Serve in Greater Smithtown

We build throughout Smithtown Township, and each community brings its own character to a project. In Smithtown itself, homes near the river tend to pair best with decks that defer to mature plantings rather than compete with them. The Village of the Branch adds historic-district considerations that reward a careful, traditional design hand. In St. James, long-settled properties - some bordering the estate-scale lots of Head of the Harbor - often call for natural wood or premium wood-look composite that suits the architecture. Nesconset brings flatter, mid-century lots where a single-level deck can stretch generously without fighting the grade. Kings Park, up near the Sound and the river mouth alongside the riverside hamlet of San Remo, gets more weather off the water, so hardware and framing choices matter more. Commack is home base - our showroom sits on Commack Road. And Hauppauge, at the township's southern edge, is full of 1960s and 1970s colonials whose original decks are exactly the second-deck candidates described above.

Visit the Showroom - You Probably Drive Past It Already

For most of the towns on this page, our Commack showroom at 119 Commack Road is a short local drive. Inside, you can walk on full-size deck displays, lean on the actual railing systems we install, compare Trex and TimberTech boards against natural wood samples, and see deck lighting glowing the way it would in your own yard. Bring photos or a survey, and a designer will start sketching around your trees, patio, and sight lines on the spot. After 39 years of building on Long Island, we have learned that decisions made standing on real decking are the ones homeowners stay happy with.

Frequently Asked Questions in Greater Smithtown

Who are the custom deck builders in Commack and Nesconset?

That would be us - Long Island Deck Company, a Decks Unique company, based right on Commack Road in Commack, minutes from Nesconset. We design and build custom decks in Trex, TimberTech, Azek PVC, and natural wood, with KDAT framing under every project, a lifetime workmanship guarantee, and Trex Platinum and TimberTech Pro certifications. Because the showroom is local, Commack and Nesconset homeowners can review materials in person before any design is finalized.

Do you do deck repair in Kings Park?

Honestly: yes, but on a seasonal schedule. Through spring and the heart of summer, our crews are committed to full builds and resurfacing projects, so we take on repair work late in the season - typically late summer into fall, when the build calendar loosens up. If your Kings Park deck has a sound frame but a tired surface, ask about resurfacing instead; it often solves the underlying problem rather than patching the symptom, and it can be scheduled like a regular project.

Can I get a retractable pergola in Smithtown?

Yes. We install retractable-canopy pergolas throughout Smithtown and the surrounding hamlets. The canopy glides open or closed along the pergola frame, so you can have full sun in May and deep shade in July without committing to either. They pair especially well with the partly shaded yards common near the river, where the light changes block by block and hour by hour.

What is an automated louvered pergola, and does it make sense here?

An automated louvered pergola has a motorized roof of rotating slats, controlled by remote or app. Open the louvers for sun, angle them for filtered light, or close them completely to shed rain - many owners use theirs as a true outdoor room from April through November. On Long Island, where a forecast can turn between the appetizer and the main course, they make a great deal of sense, and we design them into new decks or add them over existing ones.

Can you build a deck around mature trees without taking them down?

Usually, yes - and in this area we treat it as the default goal. We can frame an opening so a trunk passes through the deck, shift footings outside the critical root zone, or float sections of the structure to minimize excavation near roots. There are limits, and we will be straightforward when a tree and a deck genuinely cannot share the space, but a healthy mature tree is worth designing around. It is the shade structure you cannot buy.
