Custom Deck Design & Construction in New Cassel, NY
Built for Nassau County cold snaps and salt-air summers, and made for the kind of outdoor living you actually use.
In New Cassel, a great deck changes the rhythm of your day. It’s coffee in the quiet before the house wakes up, a place to grill while the kids run around, and soft lighting at night when you want to sit outside a little longer. We design decks that fit the real homes here-Cape Cods, Colonials, and Hi-Ranches/Split-levels-so the space feels like it always belonged. Whether you’re near Westbury, tucked by Salisbury, or just want a backyard that feels like a getaway, we’ll guide the layout, the materials, and the details that keep it looking sharp with less upkeep. Homeowners also tell us they feel comfortable choosing us because of our track record and ratings like 5.0 on Google and 94% on Facebook. And if your project falls into a category where approvals are needed, in some cases permits may be required, and we help guide the process with the Town of North Hempstead Building Department from start to sign-off.

Transforming Outdoor Living for New Cassel Homeowners
A deck should make your home feel bigger without adding a full addition. In New Cassel, we often build outdoor spaces that work like an extra room: a dining zone for family meals, a lounge area for weekend guests, and a simple set of wide steps that makes the backyard feel welcoming instead of “separate.” Cape Cods often benefit from a deck that creates a natural transition off the back door, while Colonials look incredible with a symmetrical layout, picture-frame borders, and railings that match the home’s lines. For Hi-Ranches/Split-levels, we’re careful about stair placement and sightlines so the deck feels easy to move through and not boxed-in.
We also build with everyday convenience in mind. That means planning traffic flow from kitchen to grill, leaving space for furniture that actually fits, and adding lighting that keeps things safe when you’re coming back inside after dinner. If you’re commuting along Old Country Road or hopping on the Wantagh State Parkway, the last thing you want is a long, stressful construction timeline at home. Most projects are completed in 1-2 days. You get a cleaner build experience, less disruption, and a backyard that feels like a staycation spot the moment we’re done.
Natural Wood Decking Choices
Wood has a feel that’s hard to copy-warm underfoot, classic to the eye, and perfect for homeowners who love that natural look. In New Cassel, we build many wood decks using cedar, mahogany, and pressure-treated lumber, depending on your style and budget. Cedar brings a lighter, coastal vibe and a comfortable surface. Mahogany leans rich and upscale, especially when you want deep color and a smooth, furniture-like finish. Pressure-treated is a practical choice when you want strong value and a straightforward build.
That said, we’re honest about what wood needs in Nassau County. Summer humidity, shade from trees, and everyday foot traffic can wear on a natural surface. Wood typically needs periodic cleaning and re-staining to keep it looking its best and to help it resist moisture. Some homeowners choose wood because it matches the character of an older home. Others choose it because they want the flexibility to refinish it and change the color later. Either way, we’ll talk you through the upkeep in plain terms so you’re not surprised a year or two down the road.
Trex, TimberTech & PVC Decking Options
If your goal is to spend more time enjoying the deck and less time maintaining it, composite and PVC are hard to beat. These boards are designed to resist the common issues that frustrate homeowners-splinters, heavy weathering, and constant re-staining. They’re also more consistent in shape than typical wood, which helps the finished surface look neat and feel stable as seasons change.
Trex is a favorite for families because it’s comfortable, durable, and available in a wide range of colors that fit everything from traditional Colonials to more modern updates. Trex Signature and Trex Transcend are premium choices when you want richer color and stronger long-term protection, while Trex Select is a popular middle option. Trex Enhance is often chosen when you want the composite benefits with a more budget-friendly approach. TimberTech offers its own lineup with beautiful, realistic grain patterns and color options that homeowners love when they want the deck to feel high-end from the first step outside.
PVC decking is another option some New Cassel homeowners prefer, especially when they want an especially easy-to-clean surface and strong moisture resistance. It can be a smart fit for areas that see lots of spills, pool-style entertaining, or heavy shade where dampness lingers longer. Warranty coverage varies by brand and product line, and many options fall within fade-and-stain warranty ranges that can run roughly 25 to 50 years depending on the specific board. If you’re drawn to the look of natural wood, we can also design composite colors and borders that capture that warmth-without committing you to the same maintenance routine.
Why We Use KDAT Lumber for the Substructure
KDAT stands for kiln-dried lumber, and we take it a step further by using KDAT that’s pre-stained brown. The result is framing that stays straighter and looks cleaner, because the wood has been dried in a controlled environment before it ever becomes your deck’s structure. This matters on every build, but it’s a game-changer for second-story decks where the framing is visible from below-no raw, blotchy lumber look, just a finished appearance that complements the whole backyard.
KDAT can reduce twisting and shrinking compared to standard framing, which helps the deck feel solid and look sharp over time. It’s also backed by a limited lifetime transferable warranty. And here’s a big differentiator: Decks Unique is the only decking company on Long Island offering this KDAT substructure option.
Choosing the Right Decking Materials
Material choice isn’t just about color-it’s about how you want to live on the deck. Trex Signature and Trex Transcend are premium picks when you want a deeper, more refined look with strong long-term protection. Trex Select is a balanced option that gives you the low-maintenance lifestyle without going all the way to the top tier. Trex Enhance is often chosen for smaller decks, first-time composite buyers, or anyone trying to maximize value.
TimberTech lines are a great fit when you want natural-looking grain and a wide range of tones that can match both classic and updated exteriors. And no matter which surface you choose, our KDAT framing is a big performance upgrade compared to standard framing because it’s kiln-dried and pre-finished for a cleaner, more stable structure-especially important on elevated decks. We’ll walk you through samples, real pros and cons, and the best match for your home’s style and your maintenance expectations.
Custom Features for Comfort, Style & Safety
The right features turn a basic platform into an outdoor living space you’ll actually use every day. Many New Cassel homeowners love cocktail railings because they give you a place to set a drink or small plate during gatherings. Cable railings are popular when you want a cleaner view of the yard, while vinyl railings can be a smart pick for a crisp look with simple upkeep. We’ll help you choose what fits your home and how you entertain.
Lighting makes a bigger difference than most people expect. LED stair risers help everyone see each step clearly, and post-cap lights create that soft, welcoming glow that makes the deck feel relaxing at night. For comfort, we can build shade structures that work beautifully on the generally flat to gently sloping suburban terrain common around New Cassel-think pergolas that define a seating area or a shaded dining corner that stays cooler during peak summer sun. These upgrades aren’t just “nice extras.” They help you use the deck longer each day, keep guests safer, and make the entire backyard feel more finished.
Visit Our Commack Showroom
If you’re the kind of homeowner who doesn’t want to guess from tiny samples, our Commack showroom is the perfect next step. You can walk on full-size deck displays, compare railing systems side-by-side, and see lighting demos that show what your stairs and posts will look like after sunset. We also have material samples across Trex and TimberTech lines, plus real wood selections, so you can feel the texture and see how colors work with different home styles.
Many New Cassel homeowners make the trip because it’s a convenient drive along major North Shore routes, and it saves time (and second-guessing) later. You’ll be able to sit down with a designer, review layout ideas, talk through maintenance and warranties, and leave with a clear plan you feel good about. It’s a hands-on, professional consultation-and it’s one of the easiest ways to choose confidently.
Awards & Professional Recognition
In decking, awards aren’t about trophies-they’re about proof. They tell you a company is consistent with craftsmanship, follows industry best practices, and has a reputation that holds up year after year. Decks Unique has earned recognition through respected groups like NARI and NADRA, and we’ve also been acknowledged through programs tied directly to the products we install, including Trex Platinum and TimberTech Pro. Add in BBB recognition and national industry mentions like the Remodeler 500, and it gives homeowners a simple takeaway: you’re hiring a contractor with a track record, not a roll of the dice.
NARI
NARI recognition highlights strong remodeling and construction standards. For homeowners, it signals that the company is serious about quality, documentation, and professional accountability.
NADRA
NADRA is focused on the decking industry specifically-design, safety, and proper building methods. This matters because decks need to feel great and also be built correctly where you can’t see it.
Remodeler 500
This recognition reflects experience and performance at scale. For you, it’s reassurance that your project is being handled by a team that has systems in place, not a contractor learning on your job.
Trex Platinum
Trex Platinum status is earned by contractors who meet high standards for product knowledge and installation quality. Homeowners benefit from better guidance on product choices and access to certain Trex labor coverage terms for qualifying lines.
TimberTech Pro
TimberTech Pro installers demonstrate experience with TimberTech systems and details that affect the finished look. This helps reduce common issues like sloppy trim work and mismatched components.
BBB
BBB recognition is about trust and responsiveness. For homeowners, it’s peace of mind that you’re working with a business that values communication and stands behind its work.
Our Workmanship & Product Guarantees
Decks Unique includes a lifetime workmanship guarantee, because the details of the build matter as much as the materials you choose. For Trex, qualifying projects using Signature and Transcend can include a Trex labor warranty of 10 years when installed by a Trex Platinum builder. Trex also offers fade and stain warranty coverage that varies by line: Signature/Transcend (50-year), Select (35-year), and Enhance Naturals/Basic (25-year). TimberTech products commonly carry fade and stain warranties in the 25-50-year range depending on the collection and board selected.
If you prefer natural wood, we also offer a lifetime decay guarantee for wood deck structures. And for the framing underneath, our KDAT lumber option includes a limited lifetime transferable warranty-another layer of protection for homeowners who want a cleaner, more stable substructure.
Built for New Cassel: Local Engineering Considerations
Decks in New Cassel shouldn’t be built like “generic” decks. Local soil conditions, seasonal freezing, and coastal storm patterns all influence how we plan footings, connections, and hardware. We build with Nassau County realities in mind, so your deck feels solid, drains well, and stays aligned through the seasons.
Soil & Footings
Around New Cassel you can see Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay). That blend affects how water moves and how the ground holds weight, so footing size and depth matter. We account for the local frost line at 42 inches so footings are placed deep enough to reduce shifting when the ground freezes and thaws.
Wind & Uplift Protection
Long Island weather can push structures hard, and we plan connections with wind in mind up to 120 mph. That means reinforced attachment points, proper blocking, and hurricane-rated hardware where appropriate, so the deck is better protected against uplift and racking forces during major storms.
Permits & Inspections
Every property is different, and in some cases permits may be required depending on height, size, location, and how the deck ties into the home. We help guide the process with the Town of North Hempstead Building Department, including the paperwork, scheduling, and inspection coordination so you don’t have to chase answers.
Composite vs Wood Comparison Table
| Category | Composite / PVC Decking | Natural Wood Decking |
|---|---|---|
| Everyday upkeep | Typically wash and go; no routine staining for most products | Usually needs periodic cleaning and re-staining/sealing to stay sharp |
| Look & feel | Consistent color and a clean finished appearance | Warm, natural character with unique grain and tone variation |
| Comfort & splinters | No splintering like traditional wood; comfortable for bare feet | Can splinter as it ages; comfort depends on upkeep and wear |
| Weather performance | Designed to handle moisture and seasonal swings with less movement | More likely to expand/contract and show weathering over time |
| Best fit for | Busy households, entertaining, low-maintenance priorities | Traditional style lovers, refinishing flexibility, budget-driven builds |
How We Build Decks Designed to Perform for Years
A deck looks great on day one, but the real test is how it holds up after seasons of sun, rain, and backyard life. That’s why we focus on the “invisible” details that protect the structure. We commonly use joist tape to help shield the top of framing from water, and we pay close attention to ledger flashing where the deck connects to the home to help manage moisture correctly. When the design calls for it, picture framing around the perimeter gives the deck a clean, finished border that helps the whole build look intentional and high-end.
Fasteners matter in Nassau County conditions, too. Depending on the application, we often choose stainless or ceramic-coated fasteners to help resist corrosion and staining, especially in damp areas and around plantings. We also engineer stair layouts and railing attachment points so they feel sturdy and comfortable to use. The goal is simple: a deck that feels solid underfoot, drains the way it should, and keeps its curb appeal without you constantly worrying about it.
Deck Pricing in New Cassel
Deck cost isn’t just about square footage. Pricing changes based on the material you choose (wood vs composite vs PVC), the type of railing and lighting, how many stairs and landings are needed, and whether the deck is ground-level or elevated. Even small design choices-like a picture-frame border, wider steps, or a built-in bench-can affect labor and finish details. We’ll walk the site, listen to how you plan to use the space, and then price it clearly so you know what you’re paying for and why. Financing is available for qualified homeowners.
Frequently Asked Questions
Do you handle permit paperwork for decks in New Cassel?
Yes. In some cases permits may be required, and when they are, we help guide the process with the Town of North Hempstead Building Department-applications, drawings when needed, and scheduling inspections so you’re not stuck navigating it alone.
How fast can you build my deck without dragging the job out for weeks?
For many standard residential builds, most projects are completed in 1-2 days. Larger or more complex decks (multiple elevations, long stair runs, specialty railings, or built-in features) can take longer, and we’ll set expectations before we start.
My home is a Hi-Ranch/Split-level-can a deck look “right” with that style?
Absolutely. Hi-Ranches/Split-levels are one of the best matches for a well-planned deck, especially when we design smart stairs and a layout that flows from the main living level. We’ll also consider under-deck appearance for elevated builds, which is where our pre-stained brown KDAT framing makes a big visual difference.
What’s the real difference between Trex lines like Transcend, Select, and Enhance?
It mostly comes down to the look, the level of long-term protection, and the price point. Transcend and Signature are premium, Select sits in the middle, and Enhance is often the value-focused option. We’ll show samples and help you choose based on your budget, the sunlight your yard gets, and the style you want next to your home.
Do you build decks that work well for entertaining near busy roads like Old Country Road?
Yes-many homeowners want their backyard to feel quieter and more private. We can design layout zones, add strategic privacy screens or railings, and use lighting that creates a calmer evening atmosphere so the deck feels like a retreat even when the neighborhood is active.
