Custom Deck Design & Construction in Old Westbury, NY
Built to handle Nassau County winters, and made for those easy, barefoot summer days outside.
In Old Westbury, a deck shouldn’t feel like an “add-on.” It should look like it always belonged-especially behind Large Colonials, Georgian and other estate-style homes where every detail matters. Picture a quiet morning with coffee in hand, looking out over a clean railing line and warm deck boards that feel good underfoot. Later, it’s kids running in and out, a grill going, and soft lighting making the whole yard feel like an outdoor room. We build decks that fit the look of neighborhoods like Stone Arches, Wheatley Hills, and Whitney Estates, with materials chosen for beauty now and less upkeep later. And if your project falls into a category where approvals are needed, we’ll help guide the permit and inspection process through the Village of Old Westbury Building Department so you’re not chasing paperwork. Homeowners choose Decks Unique because the work is consistent-backed by ratings like 5.0 on Google and 5.0 on Houzz-and because we build for durability, comfort, and curb appeal.

Transforming Outdoor Living for Old Westbury Homeowners
A great deck changes how you use your whole home. Breakfast doesn’t have to happen at the kitchen island. It can happen outside, with fresh air and space to breathe. Lunch becomes a quick break in the sun. And in the evening, that same deck turns into the best “room” in the house-string lights or post-cap lights glowing, family gathered around a table, and guests lingering a little longer.
Old Westbury homes-especially Large Colonials, Georgian and other estate-style homes-deserve outdoor spaces that look balanced and intentional. We design decks that match the architecture, respect the sightlines, and connect naturally to patios, pools, and backyard landscapes. We also plan smart access: wide stairs for a smooth flow, landing areas that feel safe, and railings that don’t block your view.
And yes, we keep the process simple. We handle measurements, layout, materials, and the build plan up front so you’re not guessing. Most projects are completed in 1-2 days, which means you get your yard back fast. For busy homeowners commuting along Northern State Parkway or heading up Glen Cove Road, that speed matters. You should be enjoying your deck-not babysitting a construction zone.
Natural Wood Decking Choices
Wood is still a favorite in Old Westbury for one big reason: it feels classic. Cedar has a lighter, inviting look and a natural charm that works beautifully behind traditional homes. Mahogany brings a richer tone and a more “estate” feel-great when you want the deck to look like high-end outdoor furniture. Pressure-treated lumber is often chosen when budget matters most or when the plan includes staining a custom color.
That said, wood is honest. It needs care. Nassau County humidity, summer sun, and winter moisture can dry boards out over time, then swell them back up again. To keep wood looking sharp, most homeowners plan for regular cleaning and re-sealing or staining on a schedule that fits their exposure to sun and shade. If you love the look and don’t mind a little maintenance, wood can be a beautiful choice with real character.
We’ll talk through style, slip resistance, splinters, and long-term upkeep so you pick the wood that matches your lifestyle-not just a photo you saw online.
Trex, TimberTech & PVC Decking Options
If you want a deck that looks great without spending your weekends sanding and staining, composite and PVC decking are hard to beat. These boards are made to resist the common problems that frustrate homeowners-boards that crack, splinter, or fade fast in full sun. You get a more consistent surface, comfortable bare feet, and a cleaner look year after year with simple washing.
Trex is popular for families who want long-term value and a wide range of colors. Trex Enhance is a strong “get it done” option with solid looks and easy care. Trex Select steps up the style and gives you more design flexibility. Trex Transcend and Trex Signature are the premium feel-richer grain patterns and a more polished finish that pairs beautifully with higher-end railings and lighting. TimberTech offers its own lineup with a different look and feel, and many Old Westbury homeowners choose it when they want a specific board texture or a certain color tone to match stonework, trim, or backyard plantings.
And then there’s PVC decking. Homeowners often prefer PVC when they want the lightest maintenance routine and strong resistance to moisture-especially around pools, shaded yards, or areas that stay damp longer after rain.
Warranty coverage varies by brand and product line, but many composite and PVC options fall within fade-and-stain warranty ranges of roughly 25-50 years. If you love the warmth of real timber, we can also build a natural wood deck that’s detailed beautifully and planned for the care it requires.
Why We Use KDAT Lumber for the Substructure
KDAT lumber is pressure-treated wood that’s kiln-dried after treatment, so it starts out straighter and more stable. We also use KDAT that’s pre-stained brown, which makes a huge difference on second-story decks where you can see the framing from below. Instead of the typical greenish framing look, you get a cleaner, finished appearance that looks intentional.
This also helps reduce twisting and shrinking as the deck settles in. It’s one of those upgrades you appreciate more and more over time. Decks Unique is the only decking company on Long Island offering this KDAT substructure, and it comes with a limited lifetime transferable warranty-another layer of protection for homeowners who care about quality.
Choosing the Right Decking Materials
We’ll help you match the deck to the way you live. Trex Enhance is a practical choice for busy households. Trex Select adds style upgrades. Trex Transcend and Trex Signature are for homeowners who want a premium finish that looks at home behind Large Colonials, Georgian and other estate-style homes. TimberTech has excellent options too, especially if you’re chasing a certain color, board texture, or a specific “real wood” look.
Then there’s the structure underneath. KDAT framing outperforms standard framing when it comes to straightness, cleaner appearance, and long-term stability-especially when the deck is elevated and the underside is visible. We’ll show you samples, explain the pros and cons in plain language, and help you pick a combination that looks right, feels right, and fits your budget.
Custom Features for Comfort, Style & Safety
Details are what make an Old Westbury deck feel finished. For railings, some homeowners love a cocktail rail-great for resting a drink during a party. Cable railings are a favorite when you want a modern look and a more open view. Vinyl railings can be a smart choice when low upkeep is the priority and you want a crisp, clean border.
Lighting changes everything at night. LED stair risers help people see each step clearly, and post-cap lights add a soft glow that feels upscale without being harsh. These features make the deck safer for kids, guests, and anyone carrying a plate or a glass after sunset.
We also design for comfort with shade options that work with Old Westbury’s rolling hills with gently sloping, well-drained terrain. A pergola, a roofed section, or a well-placed awning can turn a sunny deck into an all-day hangout. The result is simple: fewer bugs inside, more dinners outside, and a backyard that feels like a getaway.
Visit Our Commack Showroom
If you’re deciding between wood, composite, and PVC, seeing it online isn’t enough. At our Commack showroom, you can walk full-size deck displays, compare board colors side-by-side, and see railing systems the way they actually look at real height. We also show lighting demos-so you can understand how stair lights and post lights feel in the evening, not just how they photograph.
Old Westbury homeowners visit because it’s a convenient drive along major North Shore routes, and because it saves time and second-guessing. You can touch real samples, review design ideas with an experienced deck designer, and make choices with confidence. We’ll answer the practical questions too-what stays cooler in sun, what hides dirt better, what works best near a pool, and what fits the style of your home. It’s straightforward, hands-on guidance from people who build decks every day.
Awards & Professional Recognition
Awards matter in decking because they’re not given out for good intentions-they’re earned through real projects, consistent craftsmanship, and satisfied homeowners. When a company is recognized by respected industry groups, it usually means their designs are sound, their builds are clean, and their process is reliable. Decks Unique has earned recognition through years of detailed work, ongoing training, and a commitment to building decks that hold up in real Long Island conditions. For homeowners, these awards are peace of mind. They’re a sign you’re hiring a team that’s proven, accountable, and serious about doing it right. You’ll see names like NARI, NADRA, Remodeler 500, Trex Platinum, TimberTech Pro, and BBB-each one a different kind of trust signal.
NARI recognizes remodeling excellence, including project planning, craftsmanship, and professionalism. For you, it means the deck is treated like a true home improvement project-not a quick slap-on.
NADRA is a leading decking association focused on best practices and safety standards. This matters because your deck should feel solid underfoot and be built to current guidelines.
Remodeler 500 highlights top-performing remodeling companies across the country. Homeowners benefit because it’s a sign of stability, experience, and a company built to support you before, during, and after construction.
Trex Platinum is reserved for top-tier builders who meet strict training and performance standards. If you’re choosing Trex, this helps ensure correct installation and access to higher-level program benefits.
TimberTech Pro reflects advanced product knowledge and a track record of quality builds. It matters because premium boards deserve premium installation-clean lines, tight details, and proper fastening.
BBB Accreditation reflects a commitment to fair business practices and responsiveness. For homeowners, it’s added confidence that the company stands behind its work and communicates clearly.
Our Workmanship & Product Guarantees
We build decks to last, and we back that up with real coverage. Decks Unique includes a lifetime workmanship guarantee-so if something isn’t right with the way it was built, we’re here to make it right. For Trex, a 10-year labor warranty is available on Signature & Transcend when installed by Trex Platinum builders (like our team). Trex also offers fade and stain warranties that vary by product: Signature/Transcend (50-year), Select (35-year), and Enhance Naturals/Basic (25-year). TimberTech offers fade and stain warranty coverage that generally ranges from 25-50 years depending on the line.
If you prefer wood, we include a lifetime decay guarantee on wood decks. And for our KDAT framing, you also get a limited lifetime transferable warranty. We’ll explain what applies to your exact materials so you know what’s covered and how to keep everything in great shape.
Built for Old Westbury: Local Engineering Considerations
Old Westbury decks need more than good looks. Between the area’s rolling grades, changing seasons, and the realities of local approvals, the best results come from planning the structure the right way from day one. We pay attention to soil behavior, drainage patterns, connection strength, and the details that keep a deck stable and safe over time.
Soil & Footings
Old Westbury soils can vary between Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay). That matters because different soils hold water and settle differently. We size and place footings to match conditions and we set them to the local frost line depth of 42 inches so posts don’t shift as the ground freezes and thaws.
Wind & Uplift Protection
We build connections with high-wind performance in mind, including hardware designed for uplift resistance. With design wind speeds referenced around 120 mph, it’s important that posts, beams, and the ledger connection are reinforced so the deck acts like one locked-in system instead of separate pieces.
Permits & Inspections
In some cases, permits may be required depending on your deck’s size, height, and layout. We help guide the process with the Village of Old Westbury Building Department, including plan details and inspection scheduling, so you’re not left guessing what happens next.

How We Build Decks Designed to Perform for Years
Strong decks don’t happen by accident. We focus on the small construction details that protect the structure and keep everything tight as seasons change. We often use joist tape to help protect the tops of framing boards from trapped moisture. Ledger flashing is another key step-it helps direct water away from the connection point where the deck meets the house, which can reduce hidden water damage over time.
For a more finished look, many Old Westbury homeowners choose picture framing, where the border boards create a clean outline around the deck surface. It’s a detail that looks sharp behind high-end homes and also helps define steps and edges.
Fasteners matter too. In Nassau County conditions, we commonly use stainless or ceramic-coated fasteners where appropriate to reduce the chance of corrosion and staining. The goal is simple: a deck that feels solid, drains well, and stays attractive through hot summers, cold winters, and everything in between.
Deck Pricing in Old Westbury
Deck cost isn’t just about square footage. Materials make a big difference, and so do the details that affect labor and structure-railings, stair width, custom landings, lighting, and whether the deck is low to the ground or elevated. Homes with grade changes or complex layouts may need additional framing and footings to keep everything level and safe.
We’ll walk you through options clearly, so you can see where the money goes and what upgrades deliver the biggest daily benefit. Financing is available for qualified homeowners, which can make it easier to choose the features you really want now instead of “later.”
Frequently Asked Questions
Do you build decks that match Old Westbury’s estate-style homes?
Yes. Large Colonials, Georgian and other estate-style homes need balanced proportions, clean lines, and materials that don’t look out of place. We design the deck to match the home’s trim, stonework, and overall scale so it feels original-not like it was added years later.
How long will my deck project take once we start?
Most projects are completed in 1-2 days. Larger or more detailed builds (multiple stair runs, lighting, shade structures, or complex railings) can take longer, but we’ll give you a clear schedule before we begin.
Will I need a permit through the Village of Old Westbury Building Department?
In some cases, permits may be required based on the deck’s height, size, and how it’s attached to the home. We help guide the process with the Village of Old Westbury Building Department, including plan preparation and inspection coordination if it applies to your project.
What’s the real difference between Trex Transcend, Trex Select, and Trex Enhance?
They’re all low-maintenance boards, but they differ in style, feel, and premium finish. Enhance is a great value choice, Select adds a more upgraded look, and Transcend is a popular premium option for richer appearance and higher-end design pairings. We’ll show you samples so you can compare them in real light.
Why does KDAT framing matter if I’m using composite decking on top?
The frame is the deck’s backbone. KDAT is kiln-dried and pre-stained brown, which helps it stay straighter and look cleaner-especially on second-story decks where you can see the underside. It’s also a big part of how we deliver a more finished, high-end result.
