Custom Deck Design & Construction in Malverne, NY
Made for Nassau County winters, built for the kind of easy summer living you actually use-bare feet, cold drinks, and no constant upkeep.
Picture a quiet Malverne morning: coffee in hand, sun coming up over a neat backyard, and you’ve already got a clean, sturdy space to sit outside without dragging chairs onto the grass. That’s what a well-planned deck does-it turns “we should go outside more” into something you do every day. We design decks that fit the look and scale of local Capes, Colonials, and Ranch/High Ranch homes, so the addition feels natural, not tacked on. Whether you’re in Westwood, North Malverne, or right by the Lynbrook border area, we build for real life: grilling after work, kids coming in and out, and soft lighting that makes evenings feel calm. And if your project falls into a category where approvals are needed, in some cases permits may be required; we help guide the process with the Village of Malverne Building Department so you’re not left chasing paperwork. Homeowners choose Decks Unique for craftsmanship you can see up close and service you can feel-backed by ratings like 5.0 on Google and 94% on Facebook.

- Over 39 years of hands-on deck-building experience

Transforming Outdoor Living for Malverne Homeowners
In Malverne, a deck isn’t just “extra square footage.” It’s where your day slows down. Morning coffee outside while the neighborhood wakes up. A quick lunch in the shade. Weekend dinners that drift into the evening without everyone squeezing around the kitchen table. For Capes and Colonials, a deck creates that easy “back-of-house” hangout space-especially when the yard is your quiet escape. For Ranch/High Ranch homes, it’s a smooth step-out connection that makes the backyard feel like part of the home, not a separate zone you only use a few times a year.
We build with the way you move through the house in mind: where the door lands, how stairs should flow, and how railings should frame the view instead of blocking it. We also plan around the local layout-Malverne is generally flat to gently sloping on the suburban coastal plain, which means smart drainage and clean transitions matter for long-term comfort. And if you’re near Hempstead Avenue or Franklin Avenue, you’ll appreciate what a deck does for everyday convenience: a fast place to step outside, grill, or host without “setting up” the yard.
Most decks are completed in just 1-2 days, so you’re not living in a construction zone for weeks. We keep the experience simple: clear options, honest recommendations, and a finished deck that looks sharp and feels solid.
Natural Wood Decking Choices
Wood has a warmth you can’t fake. If you love that classic look-real grain, real character-natural wood decking can be a great fit in Malverne. Cedar is a favorite for its lighter feel and comfortable surface. Mahogany brings a rich, high-end look that pairs beautifully with traditional homes and clean landscaping. Pressure-treated lumber is often chosen for value and strength, especially when homeowners want a straightforward deck that still looks great with the right design details.
That said, wood is a relationship. Nassau County humidity, summer sun, and seasonal swings mean wood needs regular attention if you want it to stay looking its best. Plan on cleaning and protecting it over time, and expect the color to change naturally as it weathers. Many homeowners choose wood because it matches the style of their home, keeps the feel traditional, or fits a specific budget while still allowing for custom features like wide stairs, built-in benches, or a pretty railing layout.
If you want the beauty of wood but you’re not thrilled about ongoing maintenance, we’ll walk you through low-maintenance options that still look right in a Malverne backyard.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are built for homeowners who want more time enjoying the deck and less time working on it. Instead of boards that need constant sealing or staining, these materials are made to resist everyday wear-spills, sun, rain, and the kind of foot traffic that comes with family life. They stay comfortable underfoot, hold their shape well, and clean up easily with simple soap and water.
Trex is popular because it offers several levels of performance and style. Trex Enhance is a strong value choice for many families, Trex Select steps up the look and durability, and Trex Transcend and Signature deliver a more premium finish with longer warranty coverage. Trex fade-and-stain warranty terms vary by product line (Signature/Transcend up to 50 years, Select 35 years, and Enhance Naturals/Basic 25 years), which helps homeowners choose based on how long they plan to stay and how hard they expect the deck to be used.
TimberTech is another excellent choice, especially for homeowners who want a certain color palette or a specific board texture. TimberTech fade-and-stain coverage typically ranges from 25-50 years depending on the line, which is a big reason many clients compare it side-by-side with Trex.
Some homeowners prefer PVC decking when they want an even lighter-maintenance surface and excellent resistance to moisture and staining-great for entertaining, messy meals, and backyard parties. If you’re leaning toward the timeless charm of natural wood instead, we build those too, and we’ll be honest about what maintenance looks like in real life.
Why We Use KDAT Lumber for the Substructure
KDAT stands for kiln-dried after treatment, and it solves a problem many homeowners don’t notice until later: standard framing can twist, shrink, and look rough as it dries out. Our KDAT framing is kiln-dried and pre-stained brown, so it looks clean from day one and stays more stable over time. This is a huge benefit for second-story decks where the framing is visible-when you’re sitting below or walking out onto an elevated deck, you don’t want the underside to look like a patchwork of warped lumber.
It also helps the build stay straighter, which means tighter lines, cleaner railings, and a deck that feels “finished,” not just functional. Decks Unique is the only decking company on Long Island offering this, and KDAT lumber includes a limited lifetime transferable warranty for added peace of mind.
Choosing the Right Decking Materials
If you want the top-tier Trex look with premium warranty coverage, we’ll show you Signature and Transcend. If you want a great deck at a more balanced price, Select and Enhance are often the sweet spot. TimberTech offers strong choices too, especially when you’re particular about color and texture and want a wide menu of styles.
The material above matters, but what’s underneath matters just as much. KDAT framing typically outperforms standard framing because it’s more stable and looks cleaner-especially on elevated projects. We’ll help you compare materials the simple way: how it feels underfoot, what it takes to keep it clean, what it looks like next to your siding and landscaping, and how it fits your budget.
Custom Features for Comfort, Style & Safety
Malverne homeowners love decks that feel like an outdoor room, not just a platform. Railings are a big part of that. Cocktail railings give you a comfortable top ledge for drinks and small plates during get-togethers. Cable railings can open up the view and make the space feel modern and airy. Vinyl railings are a clean, classic look that stays easy to maintain and pairs well with many home styles.
Lighting is where the deck really comes alive. LED stair riser lights help you see each step clearly, and post-cap lights add soft, welcoming glow without harsh glare. It’s the kind of detail you notice when you’re outside after dinner and the whole yard feels calmer and safer.
Because the area is generally flat to gently sloping on the suburban coastal plain, shade planning is often about comfort, not fighting steep grades. We can design pergolas, privacy screens, or shade structures that work with the way the sun hits your yard and the way you actually use the space-so the deck stays cooler in the afternoon and more inviting all day.
Visit Our Commack Showroom
Deck photos are helpful, but seeing materials in person is how most homeowners make the right call. At our Commack showroom, you can walk on full-size deck displays, compare railing systems at real height, and see lighting demos so you know exactly how it will look at night. We’ll put Trex and TimberTech options side-by-side, show you color tones in different lighting, and go over wood selections if you love that natural feel.
Many Malverne homeowners make the trip because it’s convenient, it saves time, and it prevents expensive “wish we chose that one” regrets. You’ll be able to meet with a designer, review layout ideas, and talk through practical details like stairs, privacy, and traffic flow. It’s relaxed, hands-on, and guided by people who build decks every day-not a big-box aisle with guesswork.
Awards & Professional Recognition
Awards aren’t about trophies on a shelf-they’re a signal that the work is consistent, safe, and built to a standard that other pros respect. In decking, that matters because the best-looking deck still fails if it’s not engineered correctly or installed with care. Decks Unique has earned recognition through respected industry groups and programs because we focus on clean design, strong structure, and a smooth homeowner experience from planning through final walkthrough. For Malverne families, these credentials make it easier to choose confidently, knowing you’re working with a team that’s been vetted by leaders like NARI, NADRA, Trex Platinum, TimberTech Pro, and the BBB, and recognized by lists like the Remodeler 500.
NARI recognition highlights top-level remodeling craftsmanship and professionalism. For homeowners, it’s reassurance that your deck is being built with proven processes, not shortcuts.
NADRA is one of the leading deck and railing organizations in North America. Their recognition points to strong building practices and attention to detail that holds up season after season.
Remodeler 500 honors companies with a track record of performance and reliability. For you, it’s a sign you’re hiring a builder with real systems in place to keep projects on track.
Trex Platinum status reflects advanced training and high installation standards. It also matters because Platinum builders can offer Trex labor coverage on qualifying lines when applicable.
TimberTech Pro recognition shows experience with TimberTech’s premium product lineup and installation requirements. Homeowners benefit from a cleaner finish, correct spacing, and a deck built to perform.
BBB Accreditation is about trust and accountability. It’s an extra layer of confidence that you’re working with a company that stands behind its work and treats customers right.
Our Workmanship & Product Guarantees
We build decks to last, and we back that up in writing. Decks Unique includes a lifetime workmanship guarantee, so you’re not left wondering who to call if something needs attention. For Trex projects, Trex offers a 10-year labor warranty on Signature and Transcend when installed by Trex Platinum builders (terms apply). Trex fade-and-stain coverage varies by line: Signature/Transcend (50-year), Select (35-year), and Enhance Naturals/Basic (25-year). TimberTech offers fade-and-stain warranties that typically range from 25-50 years depending on the product line. If you choose natural wood, we include a lifetime decay guarantee for the wood deck structure, and for KDAT framing, you also receive a limited lifetime transferable warranty. We’ll explain what applies to your exact materials so you can choose with clarity, not guesswork.
Built for Malverne: Local Engineering Considerations
Decks in Malverne need to feel solid today and stay that way after years of weather swings, wet springs, hot summers, and coastal storms. We design around local ground conditions, proper connections, and the kind of wind events Long Island can see, so your deck doesn’t just look great-it performs the way it should.
Soil & Footings
Malverne yards can include Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay), and that mix affects how footings carry weight. We size and place footings to match the soil and we dig to the local frost line of 42 inches, helping reduce shifting as the ground freezes and thaws.
Wind & Uplift Protection
Designing for wind matters here, and we account for up to 120 mph conditions when selecting connectors and fastening methods. Reinforced connections and hurricane-rated hardware help keep the structure tied together, which is especially important on elevated decks and open yards.
Permits & Inspections
In some cases permits may be required, depending on the deck’s size, height, and location on the property. We help guide the process with the Village of Malverne Building Department, including documentation support and inspection coordination so you’re not left figuring it out alone.

How We Build Decks Designed to Perform for Years
A deck should feel tight, quiet, and stable under your feet. That comes from the details you don’t always see at first glance. We commonly use joist tape to help protect the tops of framing members from trapped moisture, which can extend the life of the structure. At the house connection, we focus on proper ledger flashing to help direct water away from the home-one of the most important steps for preventing hidden damage. For homeowners who want a clean, finished look, picture framing is a great upgrade that creates a crisp border around the deck and hides cut ends for a more polished appearance.
Because coastal conditions can be tough on standard hardware, we often recommend stainless or ceramic-coated fasteners depending on the environment and the materials selected. The goal is simple: reduce the chances of staining, corrosion, and squeaks over time. Every build is a balance of design, structure, and smart material choices, and we’ll talk through what makes sense for your specific home and yard.
Deck Pricing in Malverne
Deck pricing isn’t just about square footage. The materials you choose, the style of railing, stair size and count, lighting, built-in seating, and whether the deck is ground-level or elevated all play a major role. Even small changes-like a wider set of stairs for comfortable traffic flow-can shift the cost, but also improve how the deck feels every day. We’ll help you prioritize what matters most, then design around it. Financing is available for qualified homeowners, which can make it easier to build the deck you really want instead of settling.
Frequently Asked Questions
Do you handle the Village of Malverne Building Department paperwork if my deck needs approvals?
Yes. In some cases permits may be required based on the deck’s height, size, or placement, and we help guide the process with the Village of Malverne Building Department so you’re not stuck guessing what forms or drawings are needed.
I live near the Lynbrook border area-do you build in that part of Malverne too?
Absolutely. We build throughout Malverne, including Westwood, North Malverne, and homes close to the Lynbrook border area, and we’ll design the deck to match the home’s style and yard layout.
How fast can my deck be built once we approve the design?
Most projects are completed in 1-2 days. Larger or more complex builds (multi-level layouts, intricate lighting, or custom shade structures) can take longer, but we’ll set expectations clearly before we start.
What’s the real difference between Trex Enhance, Select, Transcend, and Signature?
Think of it as levels of style and long-term coverage. Enhance is a strong value pick, Select is a step up, and Transcend and Signature are premium options with the longest fade-and-stain warranty coverage. We’ll show samples and explain what fits your goals and budget.
Why do you recommend KDAT framing instead of standard pressure-treated lumber?
KDAT is kiln-dried after treatment and pre-stained brown, so it tends to stay straighter and looks cleaner-especially on second-story decks where you see the framing. It also comes with a limited lifetime transferable warranty, which many homeowners appreciate for long-term value.
