Custom Deck Design & Construction in Valley Stream, NY
Built to handle Nassau County winters, and made for those easy, barefoot Valley Stream summers.
Picture stepping out with your coffee while the neighborhood is still quiet, then ending the day with soft lighting, dinner outside, and room for everyone to spread out. A well-designed deck makes that feel normal-not like a special occasion. We build decks that fit the look and height of Valley Stream’s Capes, Colonials, and High Ranches, so the new space feels like it always belonged. Whether you’re in North Valley Stream, South Valley Stream, or Mill Brook, we plan around your yard, your sun, and your daily routine-grilling, homework at the table, or a calm corner for a book. If your project falls into a category where permits are needed, we help guide the process with the Village of Valley Stream Department of Buildings so you’re not chasing paperwork. Homeowners also like that we build for long-lasting beauty with low upkeep, backed by strong reviews-ratings like 5.0 on Google and 94% on Facebook-and the kind of craftsmanship that still looks sharp years later.

Transforming Outdoor Living for Valley Stream Homeowners
A great deck changes how your home feels. Suddenly there’s a real place for breakfast outside, a spot where friends can hang out while you grill, and enough room for the kids to play without everyone crowding the kitchen. For Capes and Colonials, a deck creates that “extra room” without an addition. For High Ranches, it can turn the back door into a true outdoor level-with safe stairs, clean railings, and lighting that makes evenings feel relaxed instead of dark and tricky.
We also build decks that match how Valley Stream homeowners actually live. Maybe you want an easy-care surface you can hose off after a weekend get-together. Maybe you want warm wood tones that feel classic and fit the character of the neighborhood. Either way, we keep the process simple: design help, smart material choices, and a build that’s neat and organized. Most projects are completed in 1-2 days, so you’re not living with a torn-up yard for weeks.
And let’s be honest-between Sunrise Highway (NY-27) and the Southern State Parkway, life moves fast around here. A deck gives you a reason to slow down at home. It’s your “staycation” space: dinner under the open sky, quiet mornings, and family time that doesn’t require packing up the car.
Natural Wood Decking Choices
Natural wood has a feel you can’t fake. It’s warm underfoot, it looks great against landscaping, and it fits the traditional style of many Valley Stream homes. We build wood decks with several proven options, depending on the look you want and how much maintenance you’re comfortable with.
Cedar is a favorite for its lighter tone and classic grain. It’s a great choice when you want a natural look that complements older homes and mature yards. Mahogany brings a richer, deeper color and a high-end finish-perfect when you want the deck to look like a true outdoor room. Pressure-treated lumber is often chosen for budget-friendly projects and can be finished in many stain colors to match your home.
Wood does need routine care in Nassau County humidity-usually cleaning and re-staining over time-so it stays looking sharp and protected. Some homeowners choose wood because they love the tradition. Others choose it because it’s a smart way to get a beautiful deck now, with the option to update finishes later. We’ll walk you through what to expect so there are no surprises.
Trex, TimberTech & PVC Decking Options
If you want the look of a finished deck without the yearly “to-do list,” composite and PVC are hard to beat. These boards are made to stand up to sun, rain, and everyday messes-think muddy shoes, spilled drinks, and outdoor furniture being dragged around. For many Valley Stream families, the best part is simple: you get more time enjoying the deck, and less time sanding or staining it.
Trex decking is a popular choice because it feels solid, stays more consistent over time, and comes in colors that work with both classic and modern homes. Trex offers different levels-like Enhance for a great value, Select for a step up in style, and premium options like Transcend and Signature when you want a richer look and the strongest long-term coverage. Depending on the line you choose, Trex fade-and-stain warranty ranges include 50-year (Signature/Transcend), 35-year (Select), and 25-year (Enhance Naturals/Basic) coverage.
TimberTech is another top-tier option with beautiful color choices and a sturdy feel underfoot, with fade-and-stain warranty ranges that commonly run about 25-50 years depending on the product. Some homeowners prefer PVC decking when they want the lowest upkeep possible and excellent resistance to moisture-especially for shaded areas where damp conditions can linger.
If you love the natural character of real boards, we can also design a wood deck that fits your budget and your style. The goal is the same either way: a deck that looks right, feels good to walk on, and stays easy to live with.
Why We Use KDAT Lumber for the Substructure
KDAT is a big deal if you care about the long-term look of your deck. It stands for kiln-dried after treatment, which means the framing lumber is dried in a controlled process after it’s treated. We also use KDAT that’s pre-stained brown, giving the structure a clean, finished look from day one.
This is a huge upgrade for second-story decks where the framing is visible from the yard. Instead of seeing raw, blotchy lumber underneath, you see a neat, consistent brown frame that looks intentional and high-end. KDAT also helps reduce twisting and shrinking, so your deck stays tighter and straighter as seasons change.
It’s also worth knowing: Decks Unique is the only decking company on Long Island offering this. And it comes with a limited lifetime transferable warranty, which adds extra peace of mind if you ever sell your home.
Choosing the Right Decking Materials
Material choice isn’t just about color-it’s about how you want to live on your deck. Trex Enhance is a strong value pick, while Select adds more style options. If you want the most premium look and long-term coverage, Transcend and Signature are the top end. TimberTech also offers multiple lines that range from practical to luxury, with beautiful tones that pair well with Valley Stream’s classic home styles.
Under the boards is just as important. KDAT framing outperforms standard framing in appearance and stability, especially on elevated decks where the underside shows. We’ll guide you through the options in plain language, show you samples, and help you choose a setup that fits your home, your maintenance comfort level, and your budget.
Custom Features for Comfort, Style & Safety
The right features make your deck feel like a true outdoor room. We build cocktail railings that give you a natural place to set a drink or a small plate-perfect for parties. Cable railings are great when you want a cleaner view of the yard, while vinyl railings are a smart option for homeowners who want easy cleaning and a crisp, classic look.
Lighting is another upgrade homeowners love. LED stair risers and post-cap lights add a soft glow that makes steps safer and evenings calmer. Instead of one harsh back light, you get gentle, even lighting that feels welcoming when you’re coming and going.
Because Valley Stream is Flat Coastal, shade planning matters. A well-placed pergola, roof cover, or retractable awning can turn a hot afternoon into a comfortable hangout spot. These features don’t just look good-they help you use the deck more often, keep outdoor furniture in better shape, and make the space feel finished.
Visit Our Commack Showroom
If you’re serious about building a deck, seeing materials in person makes decisions much easier. At our Commack showroom, you can walk on full-size deck displays, compare railing systems at real height, and see lighting demos so you understand what “soft evening glow” really looks like. We also have a wide range of color samples from Trex and TimberTech, plus natural wood choices, so you can match your home and backyard style with confidence.
Valley Stream homeowners visit because it’s a convenient trip along major Long Island routes, and it saves you from guessing off tiny online photos. You can sit down with a designer, review layout ideas, and talk through practical details like stairs, traffic flow, and where you’ll place a grill or dining table. It’s a relaxed, no-pressure way to get real guidance from people who build decks every day.
Awards & Professional Recognition
Awards matter in decking because they’re not handed out for good intentions-they’re earned through consistent results. When an organization recognizes a builder, it usually means the company has proven craftsmanship, reliable processes, and a track record of satisfied homeowners. Over the years, Decks Unique has earned industry and consumer recognitions by focusing on details that homeowners actually feel: clean finishes, strong structure, clear communication, and builds that hold up season after season. These awards help you choose with confidence because they show we’re not just saying we do quality work-we’ve been vetted by groups like NARI, NADRA, Remodeler 500, Trex Platinum, TimberTech Pro, and the BBB.
NARI recognizes remodeling excellence and strong business standards. For homeowners, it’s a sign you’re hiring a builder who’s committed to quality work and professional project management.
NADRA focuses on outdoor living expertise and craftsmanship. This matters because decks are exposed to weather year-round, and NADRA recognition signals strong building habits that protect your investment.
Remodeler 500 highlights top-performing remodelers based on proven performance and stability. For you, that translates to a company with the staffing and systems to complete work smoothly and stand behind it.
Trex Platinum is a top contractor level earned through experience and ongoing performance. Homeowners benefit from trained installation practices and access to premium warranty options tied to Platinum builders.
TimberTech Pro recognizes contractors who install TimberTech products to professional standards. That means your deck is built to match manufacturer guidelines, helping it look better and perform longer.
BBB Accreditation reflects a commitment to trust and customer service. For homeowners, it’s reassurance that you’re working with a company that values accountability and clear communication.
Our Workmanship & Product Guarantees
We build decks the way we’d want them built for our own families-clean, strong, and done right. Decks Unique includes a lifetime workmanship guarantee so you can feel confident in the way the deck is put together. If you choose Trex, there’s also a 10-year labor warranty available on Signature & Transcend when installed by Trex Platinum builders. Trex fade-and-stain warranties vary by product line: 50 years for Signature/Transcend, 35 years for Select, and 25 years for Enhance Naturals/Basic.
TimberTech products also include strong coverage, with 25-50-year fade-and-stain warranty ranges depending on the line. Prefer wood? Our wood decks include a lifetime decay guarantee. And for the framing, our KDAT lumber comes with a limited lifetime transferable warranty. We’ll explain the warranty options clearly so you know what applies to your exact material choices.
Built for Valley Stream: Local Engineering Considerations
Valley Stream decks need more than good looks-they need smart planning for local ground conditions, coastal weather patterns, and safe connections that hold up year after year. We design with real-world factors in mind, so your deck feels solid underfoot and stays that way through changing seasons.
Soil & Footings
In Valley Stream, we often see Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay). That mix affects how water drains and how the ground holds weight. We place footings to reach the local frost line of 42 inches, which helps prevent seasonal freeze-and-thaw movement from shifting your deck over time.
Wind & Uplift Protection
Decks here should be planned with wind events in mind, up to 120 mph. We use reinforced connections and hurricane-rated hardware where appropriate so the deck is better protected against uplift and racking forces, especially on elevated structures and open, windy yards.
Permits & Inspections
In some cases, permits may be required, depending on your deck’s size, height, and location on the property. We help guide the process with the Village of Valley Stream Department of Buildings, including planning details and inspection coordination, so the experience stays straightforward.
Composite vs Wood Comparison Table
| Feature | Composite / PVC Decking | Natural Wood Decking |
|---|---|---|
| Everyday upkeep | Typically soap-and-water cleaning; no routine staining in most cases | Usually needs periodic cleaning and re-staining/sealing to keep it looking its best |
| Look & feel | Consistent color and finish; comfortable, refined appearance | Natural grain, warmth, and traditional character |
| Weather performance | Made to resist fading and staining; good stability through seasonal changes | Performs well when maintained; more sensitive to sun, moisture, and wear |
| Long-term value | Great for homeowners who want “set-it-and-enjoy-it” living | Great for homeowners who love real wood and don’t mind routine care |
| Best fit for | Busy households, entertainers, and low-maintenance goals | Classic style, natural look, and budget-conscious builds |
How We Build Decks Designed to Perform for Years
A deck can look beautiful on day one and still disappoint if the hidden details aren’t handled right. That’s why we focus on the parts you don’t always notice at first glance. We often use joist tape to help protect the tops of the framing from trapped moisture, which can support longer-lasting structure. We also pay close attention to ledger flashing where the deck meets the home, helping direct water away from sensitive areas.
For a clean, finished look, many homeowners choose picture framing-a border around the deck surface that gives it a polished, custom feel and helps define the space. And because Nassau County weather can be tough on exposed metal, we typically use stainless or ceramic-coated fasteners where appropriate to help reduce corrosion and keep hardware looking better over time.
The goal is simple: a deck that feels solid, drains well, and keeps its good looks through everyday life-furniture, foot traffic, kids, pets, and all.
Deck Pricing in Valley Stream
Deck pricing isn’t just about square footage. Materials play a big role (wood vs composite vs PVC), but so do the details that make the deck comfortable and safe: railings, stair runs, lighting, patterns, and whether the deck is ground-level or elevated. Even the layout of your yard-like elevation changes or the best place to land the stairs-can affect labor and structure needs.
We’ll help you compare options honestly so you can choose what fits your home and your budget without cutting corners that matter later. Financing is available for qualified homeowners, which can make it easier to build the deck you really want instead of settling for a smaller plan.
Frequently Asked Questions
How does the Village of Valley Stream Department of Buildings affect my deck plan?
Some deck designs trigger more review than others-especially when height, stairs, or placement near property lines come into play. If your project needs approvals, we help guide the process with the Village of Valley Stream Department of Buildings and keep the paperwork and inspection steps organized.
In some cases, are permits required for a deck in Valley Stream?
Yes-in some cases, permits may be required based on the deck’s size, elevation, and how it connects to the home. We’ll look at your specific plan and help you understand what applies, then guide the process if filings are needed.
How fast can you build my deck once we approve the design?
After design choices and scheduling are locked in, most projects are completed in 1-2 days. Larger or more complex builds can take longer, but we’ll set expectations clearly before we begin.
What’s the best choice for a High Ranch-Trex, TimberTech, or wood?
High Ranch decks are often elevated, so many homeowners lean toward Trex or TimberTech for low upkeep and long-term color performance. If you want the warmth of real boards, wood can be a great fit too. We’ll review your sun exposure, how you use the space, and your maintenance comfort level to help you decide.
Why are you recommending KDAT framing for my second-story deck?
Because you’ll see it. KDAT is kiln-dried and pre-stained brown, so the underside looks cleaner and more finished from the yard. It also tends to stay straighter with less twisting, and it comes with a limited lifetime transferable warranty.
