Transforming Outdoor Living for Manhasset Hills Homeowners
A great deck isn’t just “more square footage.” It’s where life happens when you’re home. It’s breakfast outside on a quiet weekday, a place for kids to do homework in the breeze, and an easy spot to host family without crowding the kitchen. For Post-war Colonials, Capes, and Split-Level/High Ranch homes, the right deck design can solve common layout issues-like tight back doors, uneven yards, or that awkward step-down from the home into the yard. We design the deck to match how you move through your house, so it feels like a natural extension, not an add-on.
Manhasset Hills homeowners also love the “staycation” feel: a clean composite surface, sturdy railings, and warm lighting can turn an ordinary backyard into the spot you choose over another drive up Hillside Avenue (NY-25B) or a quick hop onto the Northern State Parkway. Add a dining area, a grilling zone, and a lounge corner, and you’ve got a backyard that actually gets used.
We keep the process straightforward-design help, material guidance, and solid construction practices that hold up in Nassau County weather swings. And when it’s time to build, we work efficiently: Most projects are completed in 1-2 days. That means less disruption, less mess, and you enjoying the space sooner.
Natural Wood Decking Choices
Natural wood still has a look you can’t fake-warm, rich, and full of character. In Manhasset Hills, we build wood decks with popular choices like cedar, mahogany, and pressure-treated lumber, depending on the style of the home and how you plan to use the space. Cedar gives you a classic, lighter-toned beauty and a comfortable feel underfoot. Mahogany brings a deeper, upscale look that pairs beautifully with traditional architecture. Pressure-treated is the practical workhorse-great for homeowners who want a strong deck at a more budget-friendly starting point.
Wood does ask for honest upkeep, especially with Nassau County humidity and summer sun. To keep it looking its best, most wood decks need periodic cleaning and re-staining or sealing over time. If you love the natural grain, want a traditional feel, or you’re matching an older home style, wood can be the perfect fit-as long as you’re comfortable with the maintenance plan. We’ll talk it through clearly so you know what to expect before you commit.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are popular in Nassau County for one simple reason: you get a polished, consistent look without the endless cycle of sanding and staining. Composite boards are made to resist common backyard problems like splinters, surface checking, and the day-to-day wear that comes with pets, parties, and muddy shoes. They’re also easier to keep clean-most of the time, a basic wash is all you need to get your deck looking fresh again.
Trex offers several lines so homeowners can pick the right blend of style, performance, and budget. If you want a premium look with the most refined color choices, we’ll walk you through Trex Signature and Transcend. For a strong balance of looks and value, Trex Select is a common choice. For budget-minded projects where you still want the low-maintenance benefit, Trex Enhance is often the best fit. TimberTech also gives homeowners a wide design range, including options that lean modern, coastal, or traditional, depending on the home.
PVC decking is another option some families prefer, especially when low upkeep is the top priority and you want a surface designed to handle tough outdoor conditions. Warranty coverage varies by product line, but many composite and PVC options include fade-and-stain coverage in ranges like 25 to 50 years. If you love the idea of a deck that stays consistent season after season, composite or PVC is worth a serious look. If you’re drawn to natural grain and don’t mind scheduled maintenance, wood may still be your favorite-either way, we’ll help you choose with zero guesswork.
Why We Use KDAT Lumber for the Substructure
KDAT means the framing lumber is kiln-dried, and we use it pre-stained brown for a cleaner finished look. This matters more than most homeowners realize, because your deck’s strength comes from the frame-not just the surface boards. Kiln-drying helps the lumber stay more stable, which can reduce twisting and warping as the seasons change. The brown stain also makes the framing look neat and intentional instead of blotchy and unfinished.
This is a huge advantage for second-story decks where the framing is visible from below-whether you’re looking out a basement door, standing on a patio, or just enjoying the view across the yard. And it’s a real differentiator: Decks Unique is the only decking company on Long Island offering this. KDAT lumber also comes with a limited lifetime transferable warranty, which adds long-term value for homeowners who think ahead.
Choosing the Right Decking Materials
Picking materials should feel simple, not overwhelming. Trex Signature and Transcend sit at the top end for homeowners who want the most upgraded look. Trex Select is a smart middle ground, and Trex Enhance is often the go-to for families who want low upkeep while keeping the budget controlled. TimberTech offers a broad set of choices too, especially if you’re trying to match a certain home style or want a specific color tone.
Just as important as the surface is what holds it up. Our KDAT framing outperforms standard “wet” framing because it’s more stable and looks cleaner-especially on elevated builds. We’ll help you compare boards, colors, railings, and real-life feel so the final choice matches your home, your yard, and how you’ll actually use the space.
Custom Features for Comfort, Style & Safety
The best decks aren’t just flat platforms-they’re tailored outdoor rooms. Railings are a big part of that. Cocktail railings give you an easy place to rest a drink or a plate during a BBQ. Cable railings keep the view open and feel modern, which works great when you want the yard to feel bigger. Vinyl railings are a clean, classic option that stays neat with minimal upkeep.
Lighting is where the deck really comes alive. LED stair risers help you see every step clearly, and post-cap lights add soft, welcoming glow without feeling harsh. It’s the difference between “we should go inside, it’s dark” and “let’s sit out for one more hour.” We can also build shade features that make sense for Manhasset Hills’ gently rolling suburban terrain-so you get coverage where you need it, without making the yard feel closed in. The goal is simple: safer steps, more comfort on hot days, and a backyard that feels finished from every angle.
Visit Our Commack Showroom
If you want to feel confident about your choices, come visit our Commack showroom. Seeing a deck board online is one thing-walking on full-size displays is another. In our showroom, you can compare Trex and TimberTech options side-by-side, explore real wood selections, and review railing systems in person. We also have lighting demos, so you can see how stair lights and post-cap lighting look at night-level brightness, not just in a catalog photo.
Homeowners from Manhasset Hills often stop in because it’s a convenient drive along major North Shore routes, and it saves weeks of second-guessing. You can sit down with a designer, talk through layout ideas, and match colors to your home with real samples in your hands. It’s a relaxed, no-pressure way to plan, and it helps you make decisions you’ll still love years from now.
Awards & Professional Recognition
Awards matter in decking for the same reason inspections matter-they’re a third-party signal that the work is being done the right way, consistently. In a world where anyone can claim they “build decks,” recognition from respected industry groups shows real training, real standards, and a track record of quality. Decks Unique has earned these honors through steady craftsmanship, strong customer communication, and builds that are designed to last. For homeowners in Manhasset Hills, these awards make it easier to choose confidently, knowing you’re hiring a contractor recognized by NARI, NADRA, Remodeler 500, Trex Platinum, TimberTech Pro, and the BBB.
NARI recognizes remodeling excellence and ethical business practices. For homeowners, it’s reassurance that your project is being handled by a team that values workmanship, professionalism, and follow-through.
NADRA is a leading deck and railing association focused on safety and education. This matters because deck building isn’t just design-it’s structure, fasteners, and connections that protect your family.
Remodeler 500 highlights top-performing remodeling companies across the country. For you, it signals stability: a company with systems, support, and experience to deliver on schedule and stand behind the work.
Trex Platinum status is reserved for contractors with proven training and volume with Trex products. Homeowners benefit from experienced installation practices and access to upgraded labor warranty options on qualifying lines.
TimberTech Pro recognition reflects product knowledge and correct installation methods. That helps your deck look better, feel more solid, and perform the way it’s supposed to for years.
BBB Accreditation is about trust, responsiveness, and accountability. If you want a contractor who answers the phone, handles concerns, and runs a clean business, this is a meaningful credential.
Our Workmanship & Product Guarantees
We believe a deck should come with peace of mind, not “hope it holds up.” Decks Unique includes a lifetime workmanship guarantee-because the way a deck is built matters just as much as the materials you choose. For Trex, qualified lines like Signature and Transcend can include a 10-year labor warranty when installed by Trex Platinum builders (that’s us). Trex fade-and-stain warranty coverage varies by product, with typical terms such as 50 years for Signature/Transcend, 35 years for Select, and 25 years for Enhance Naturals/Basic. TimberTech also offers fade-and-stain coverage that commonly ranges 25-50 years depending on the line.
If you prefer natural wood, we offer a wood deck lifetime decay guarantee, and our KDAT framing includes a limited lifetime transferable warranty. We’ll review the exact warranty language for the products you pick, so you know what’s covered and how to keep it valid.
Built for Manhasset Hills: Local Engineering Considerations
Decks in Manhasset Hills have to perform through real seasonal change-freeze-thaw cycles, summer storms, and everyday family use. We plan for the ground below, the wind above, and the local process that keeps projects moving smoothly. The result is a deck that feels solid underfoot and stays that way.
Soil & Footings
Backyards here can include Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay), and each one drains and settles differently. We size and place footings to reach the 42 inches frost line and to rest on stable ground, helping prevent shifting that can lead to dips, squeaks, or uneven stairs.
Wind & Uplift Protection
We build with wind events in mind up to 120 mph. That means reinforced connections, proper blocking, and hurricane-rated hardware where needed so the deck is tied together as a system, not just fastened board-by-board.
Permits & Inspections
In some cases, permits may be required, depending on height, size, and how the deck connects to the home. We help guide the process with the Town of North Hempstead Building Department, including the documents, scheduling, and inspection readiness, so you don’t have to learn the process the hard way.

How We Build Decks Designed to Perform for Years
Long-lasting decks aren’t an accident-they’re built into the details you don’t always notice on day one. We often use joist tape to protect the tops of the framing from moisture, which can help extend the life of the structure. At the house connection, we pay close attention to ledger flashing so water is directed away from the home instead of being trapped where it can cause problems over time. For finishing, picture framing can give the deck a clean “built-in” look, especially on composite projects where homeowners want a crisp border.
Fasteners matter on Long Island too. Depending on the material and exposure, we may use stainless or ceramic-coated fasteners to better handle Nassau County conditions. The goal is simple: reduce the chances of rust, staining, and callbacks, while keeping the surface neat and secure. We’ll explain what we’re using and why, so you know your deck isn’t just pretty-it’s put together with intention.
Deck Pricing in Manhasset Hills
Deck pricing is more than measuring length and width. Costs can shift based on the material line you choose, railing style, stair design, and whether the deck is ground-level or elevated. Details like picture framing, lighting, and built-in seating can also change the final number-sometimes a little, sometimes a lot. Even the yard layout matters; gently rolling grades can affect stairs, landing needs, and how we transition into the landscape.
We’ll walk you through options that make sense for your home and your budget, with clear trade-offs so you’re never guessing. Financing is available for qualified homeowners, and we’re happy to price a few smart alternatives so you can compare confidently.
Frequently Asked Questions
Do you build decks that match the look of Post-war Colonials and Split-Level/High Ranch homes in Manhasset Hills?
Yes. Those home styles often benefit from a deck that solves traffic flow-where you step out, where stairs land, and where dining or grilling fits without feeling cramped. We design around the house architecture so the deck feels original to the property.
How long does construction take once we approve the design?
For many standard projects, most projects are completed in 1-2 days. Larger builds or decks with complex stairs, lighting, or multiple levels can take longer, but we’ll set expectations upfront and keep the job moving.
Will I need a permit through the Town of North Hempstead Building Department?
In some cases, yes-often based on deck height, size, and how it attaches to the house. We help guide the process with the Town of North Hempstead Building Department, including the paperwork and inspection readiness, so it’s not a stress point for you.
What’s the advantage of KDAT framing versus standard pressure-treated framing?
KDAT framing is kiln-dried and pre-stained brown, so it’s more stable and looks cleaner-especially on second-story decks where you can see the framing from below. It also includes a limited lifetime transferable warranty, which is a nice long-term value add.
If I’m near Hillside Avenue or close to the Northern State Parkway, does access affect the build?
Sometimes. Driveway access, side-yard clearance, and where materials can be staged can affect how we plan the workday. We’ll review access during the site visit and set up a plan that protects your property and keeps the project efficient.
