Transforming Outdoor Living for North Valley Stream Homeowners
A great deck doesn’t just “add square footage.” It changes how your home feels. Suddenly there’s a spot for breakfast outside, a place to grill without juggling trays through the kitchen, and room for friends to gather without everyone standing in one doorway. For Capes, Colonials, and High Ranches, we design decks that look like they belong there-balanced railings, properly sized stairs, and layouts that make the yard feel bigger and easier to use.
North Valley Stream homeowners often tell us they want a backyard they actually use. Between busy weeks and quick commutes, it’s nice to turn a regular evening into a mini staycation-especially when you’re minutes from the Southern State Parkway or cruising down Dutch Broadway and just want to get home, kick off your shoes, and relax. We plan for cooking zones, seating zones, and clear walking paths so the deck works even when a dozen people are over.
And we keep the process simple. We handle measuring, design help, material guidance, and clear scheduling-so you’re not chasing answers. Most decks are completed in just 1-2 days, which means less disruption and faster enjoyment. If inspections are part of your project, we’ll coordinate and help guide the steps so you don’t feel stuck in paperwork.
Natural Wood Decking Choices
Wood has a look you can’t fake. If you love a warm, classic feel underfoot, natural wood decking is still a great choice-especially for homeowners who want that traditional backyard style. Cedar is a popular option for its natural charm and lighter weight, and it can look beautiful around gardens and older landscaping. Mahogany brings a richer, deeper tone and an upscale finish that pairs nicely with many Colonial-style homes. Pressure-treated wood remains a practical choice when budget matters and you want a strong, time-tested deck surface.
That said, we’re always straight with homeowners about upkeep. Nassau County humidity, shade, and wet seasons can be tough on wood. To keep it looking its best, wood typically needs regular cleaning and periodic sealing or staining. If you don’t keep up with it, boards can fade, splinter, or grow slippery over time. Some families choose wood because they enjoy maintaining it, while others choose it because they prefer the real-grain look or want a cost-effective way to build a larger deck. We’ll help you weigh appearance, comfort, and ongoing maintenance before you commit.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are popular for one main reason: they make outdoor living easier. These boards are designed to resist the common problems that frustrate homeowners-like constant repainting, frequent sealing, and heavy weather wear. Composite decking is made to look like natural wood, but it’s built to be more consistent from board to board, with better stability through seasonal temperature swings. Many homeowners love how it feels underfoot, how clean it stays, and how simple it is to wash with basic soap and water.
Trex offers multiple lines so you can match your goals and budget. Trex Signature and Trex Transcend are top-tier choices for homeowners who want the deepest color options and a premium finish. Trex Select is a strong middle-ground when you want a clean look without going all the way to the top line. Trex Enhance is often chosen for value-especially for families who want low upkeep without sacrificing curb appeal.
TimberTech also offers excellent options, with styles that range from classic to bold and modern. Depending on the collection, you’ll see different texture choices and color tones that can complement everything from light siding to darker trim packages. And for homeowners who want the most “hose-it-off and move on” kind of deck, PVC is worth a look. PVC boards are made to handle moisture extremely well, which can be appealing in shaded yards or around pools and hot tubs.
Warranty coverage varies by product, but many lines fall within fade-and-stain warranty ranges of roughly 25 to 50 years. If you love the look of real wood, we can compare that side-by-side too, so your choice feels confident-not rushed.
Why We Use KDAT Lumber for the Substructure
KDAT lumber is pressure-treated wood that’s kiln-dried after treatment, which helps it stay straighter and more stable as the deck lives through real Long Island weather. We also use KDAT that’s pre-stained brown, so the framing looks clean and intentional instead of the usual green-tinted look. That’s a huge upgrade for second-story decks, where you can often see the structure from below-especially from patios, walkways, or sliding doors.
The result is a tighter-looking deck with fewer twists and a more finished appearance from every angle. It’s also backed by a limited lifetime transferable warranty. And here’s the part that truly sets us apart: Decks Unique is the only decking company on Long Island offering this KDAT substructure upgrade.
Choosing the Right Decking Materials
If you want the best of the best in feel and finish, many homeowners lean toward Trex Signature or Transcend. If you want a strong balance of appearance and price, Trex Select is a common sweet spot. If value is the priority, Trex Enhance can be a smart path. TimberTech offers comparable steps across its lines too, giving you a range of color and texture choices.
Below the boards, framing matters just as much. A KDAT substructure outperforms standard framing in straightness and looks-especially on elevated builds where the underside is visible. We’ll walk you through samples, explain what you’re paying for, and help you choose a system that fits your home, your yard, and how you actually plan to live on the deck.
Custom Features for Comfort, Style & Safety
The difference between a basic deck and a “favorite place to be” often comes down to the details. For railings, we build and install options like cocktail railings (great for resting a drink or a plate), modern cable railings that keep the view open, and low-maintenance vinyl railings that stay crisp and clean. Each one is chosen to improve safety while matching the home’s style.
Lighting is another game-changer. LED stair riser lights help prevent missed steps at night, and post cap lights add a soft glow that makes the whole yard feel calmer and more welcoming. It’s the kind of lighting you notice when you’re sitting outside after dinner-everything feels warm, not harsh.
For shade, we can design structures that make sense for the flat coastal plain-where sun can feel intense and wind can pick up quickly. A well-placed shade cover or pergola-style structure can cool the space, protect furniture, and extend your outdoor season. The goal is simple: a deck that looks great, feels safe for every age, and makes you want to step outside more often.
Visit Our Commack Showroom
If you’re the kind of homeowner who wants to see it before you buy it, our Commack showroom is the right next step. You’ll be able to walk up to full-size deck displays, compare railing systems at real height, and see lighting demos that photos just don’t capture. We also have material samples you can touch-Trex and TimberTech options side-by-side, plus wood choices-so you can feel the textures and see how colors change under different lighting.
Homeowners from North Valley Stream often stop in because it’s a convenient drive and it saves time later. Instead of guessing from small samples, you can make a confident decision in one visit. You can also meet with a designer, review layout ideas, and talk through practical details like stairs, traffic flow, and privacy. It’s a relaxed, professional way to plan your project-and it helps you move forward with clarity.
Awards & Professional Recognition
Deck building looks simple from the outside-until you learn how much depends on correct structure, safe connections, and clean finish work that holds up year after year. That’s why industry awards matter. They’re not popularity contests; they reflect training, standards, and consistent performance across many projects. Over the years, Decks Unique has earned recognition through craftsmanship, ongoing education, and a track record of building decks that homeowners truly enjoy living on. For you, these awards mean you’re hiring a company that’s been vetted by respected organizations like NARI and NADRA, recognized by programs like Remodeler 500, and trusted by major brands like Trex and TimberTech. Even BBB accreditation adds another layer of confidence when choosing a contractor.
NARI recognizes remodeling excellence and professionalism. For homeowners, it’s a sign that your deck builder follows high standards for design, construction, and customer care.
NADRA is a leading deck and outdoor living association focused on safety and best practices. This matters because your deck should be beautiful, but it must also be built correctly from the inside out.
Remodeler 500 highlights top-performing remodeling companies nationwide. For you, it signals proven systems, dependable production, and experience handling projects the right way.
Trex Platinum status is earned through training, volume, and quality installation. Homeowners benefit from product knowledge and access to specific warranty programs tied to Platinum builders.
TimberTech Pro recognition reflects brand-specific education and proper installation methods. That helps protect performance, appearance, and long-term value.
BBB Accreditation shows a commitment to transparent, ethical business practices. For homeowners, it’s one more way to feel comfortable about who you’re letting work on your home.
Our Workmanship & Product Guarantees
We stand behind our work with a Decks Unique lifetime workmanship guarantee, because the build quality matters as much as the materials you choose. On the product side, Trex offers a 10-year labor warranty for Signature & Transcend when installed by Trex Platinum builders. Trex fade & stain warranty coverage varies by line: Signature/Transcend carry 50-year coverage, Select carries 35-year coverage, and Enhance Naturals/Basic carry 25-year coverage. TimberTech products also include fade & stain warranties that typically range from 25 to 50 years depending on the collection.
If you prefer natural lumber, we offer a wood deck lifetime decay guarantee. And for the framing upgrade, KDAT lumber includes a limited lifetime transferable warranty. We’ll review the exact warranty language for the products you select so you know what’s covered and how to keep everything in good standing.
Built for North Valley Stream: Local Engineering Considerations
Decks in this part of Nassau County need more than nice boards on top. We design for the site, the ground, and the weather patterns you actually live with-so your deck feels solid, drains well, and stays secure through the seasons.
Soil & Footings
North Valley Stream yards commonly have Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay). That mix affects drainage and how tightly the soil holds a footing. We size and place footings to reach the frost line at 42 inches, helping reduce shifting and movement as the ground freezes and thaws.
Wind & Uplift Protection
Designing for up to 120 mph wind means the deck can’t rely on nails and hope. We use reinforced connections and hurricane-rated hardware in key areas, helping the deck resist lifting forces and racking when strong weather rolls through.
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 Valley Stream Building Department, including plan needs and inspection coordination, so it feels straightforward instead of stressful.
Composite vs Wood Comparison Table

| Comfort in different seasons | Designed for stability through temperature changes | Can expand/contract more and may need board replacement over time |
| Best for | Low-maintenance living, busy families, long-term color retention | Traditional style, natural beauty, and homeowners comfortable with maintenance |
| Budget flexibility | Wide range from value lines to premium collections | Often lower entry cost depending on species and design |
How We Build Decks Designed to Perform for Years
A deck lasts longer when the hidden parts are done right. We use joist tape on key framing surfaces to help shed water and reduce moisture sitting where it shouldn’t. Ledger flashing is another big deal-it helps protect the connection point between your home and the deck, reducing the chance of water getting trapped behind the structure.
When the design calls for it, we add picture framing around the deck perimeter for a clean, finished look that also helps protect board ends. For fasteners, we often recommend stainless or ceramic-coated options that hold up well in Nassau County conditions, especially where moisture and seasonal changes can wear on standard hardware.
None of this is about overbuilding for the sake of it. It’s about smart building-details that help your deck stay tighter, look better, and feel safer as the years go by.
Deck Pricing in North Valley Stream
Deck cost isn’t just about square footage. Materials make a big difference, but so do railings, stairs, lighting, built-in seating, and whether the deck is low to the ground or elevated off the house. Yard layout matters too-grades, existing patios, and how we tie into your home safely can affect the scope. The best way to get real numbers is to look at your space and build a plan around how you want to use it.
Financing is available for qualified homeowners, which can make it easier to choose the materials and features you actually want instead of settling.
Frequently Asked Questions
Do you work with the Village of Valley Stream Building Department, or do I have to handle that?
We help guide the process. If your project needs filings or inspections, we’ll walk you through what’s required, help prepare the right paperwork, and keep things moving so you’re not chasing answers on your own.
In North Valley Stream, are permits always required for a new deck?
No-every project is a little different. In some cases, permits may be required based on the deck’s height, size, or how it’s attached. We’ll review your plan and explain the likely path before construction starts.
How fast can you build my deck once we choose the design?
Most projects are completed in 1-2 days. Larger or more complex builds (multiple levels, lots of stairs, specialty lighting, or custom features) can take longer, but we’ll give you a clear schedule up front.
What’s the best decking for a busy family-Trex, TimberTech, PVC, or wood?
For many busy households, Trex or TimberTech composite is a great fit because it keeps upkeep low and stays consistent in appearance. PVC can be ideal when you want the easiest cleanup and strong moisture resistance. Wood is still a beautiful option when you want natural character and don’t mind regular maintenance.
Why are you recommending KDAT framing instead of standard pressure-treated wood?
KDAT is kiln-dried after treatment and comes pre-stained brown, which helps it stay straighter and look cleaner-especially on second-story decks where you can see the framing from below. It’s also a unique upgrade: Decks Unique is the only decking company on Long Island offering this KDAT substructure option.
