Built for Nassau County winters, and made for the kind of easy summer living that makes you want to stay outside a little longer.
Picture a quiet morning with coffee on a clean, solid deck-no splinters, no wobbles-just space to breathe.

We design decks that look right on the house and hold up to real Long Island life: wet springs, salty air near the Sound, and busy weekends with friends and family. From Port Washington North to Manorhaven and Baxter Estates, we help you choose materials that match your style and your schedule-low-maintenance composite, modern PVC, or the warmth of real wood. And if, in some cases, a permit is required, we help guide the process with the Town of North Hempstead Building Department so you’re not stuck chasing paperwork. Homeowners also find comfort in our reputation, with ratings like 5.0 on Google and 94% on Facebook.

Transforming Outdoor Living for Port Washington Homeowners
A great deck changes how you use your home. Dinner doesn’t feel cramped because you can set up a real outdoor table. Kids have room to play while the adults talk. And when the sun drops, soft lighting on the steps makes the whole yard feel calm and inviting. For many Port Washington homes-especially Colonials, Capes, and Split/High Ranches-a custom deck is the missing “everyday space” that makes the house feel larger without a full addition.
We build decks that fit your routine. Maybe you want a small spot for morning coffee and a grill, or maybe you want a wide entertaining layout with benches and defined zones. Either way, we design it to flow naturally from your back door and match the look of your home, so it doesn’t feel like an afterthought. And because we’ve built across Nassau County for decades, we know how to plan for the things homeowners worry about: safe stairs, solid railings, smooth transitions, and materials that won’t have you sanding every season.
When you’re driving Port Washington Boulevard (NY-101) or taking a turn down Shore Road, you see how many different yard shapes and elevations there are. We account for that from day one. And when it’s time to build, we keep it efficient-most projects are completed in just 1-2 days.
Natural Wood Decking Choices
Some homeowners simply love real wood. It has warmth you can’t fake, and it looks right at home on traditional Long Island architecture. We build wood decks using proven options like cedar, mahogany, and pressure-treated lumber. Cedar is a great pick when you want a lighter, classic look and a comfortable feel under bare feet. Mahogany brings a richer, more upscale tone that can make a simple backyard feel like a resort. Pressure-treated wood is often chosen for budget-friendly builds and for homeowners who want a strong, straightforward deck that can be stained any color they like.
Here’s the honest part: wood needs care-especially in Nassau County humidity. Sun, rain, and salty air can dry it out, fade it, and make it rough if it’s ignored. Most wood decks do best with regular cleaning and periodic staining or sealing to keep the color even and the surface smooth. If you like the idea of maintaining it (or you love the natural aging look), wood can be a great choice. If you’d rather spend weekends relaxing instead of refinishing, we’ll show you composite and PVC options that keep their look with much less work.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are popular in Port Washington because they’re built for busy homeowners. Instead of dealing with splinters, constant staining, or boards that change shape season to season, you get a surface designed to stay comfortable, stable, and easy to care for. Most of the time, maintenance is simple: a basic wash to remove pollen and everyday dirt, and you’re done.
Trex is a go-to choice for families who want a dependable deck that holds color well and stays consistent over the years. Trex offers different levels-like Enhance, Select, Transcend, and Signature-so we can match your goals and budget. Some lines focus on value and clean style, while others focus on deeper color, more detailed grain patterns, and a higher-end look.
TimberTech is another premium option, known for beautiful color choices and strong performance. Homeowners often choose TimberTech when they want a very refined finish and a wide range of design styles, from coastal tones to modern browns and grays.
PVC decking is often the pick when homeowners want the highest level of stain resistance and the easiest cleanup-great for heavy entertaining, outdoor dining, and pool-style living (even if you’re just building the “staycation” vibe). Many composite and PVC products also include strong fade-and-stain warranty ranges (often around 25-50 years depending on the product line), which gives homeowners added peace of mind.
And if you still love the look of natural wood, we can design the deck to bring that warmth in-sometimes through wood accents, sometimes through color choices that blend beautifully with classic siding and trim.
Why We Use KDAT Lumber for the Substructure
KDAT lumber is one of those “you don’t see it on day one, but you appreciate it for years” upgrades. KDAT stands for kiln-dried after treatment, which means the framing lumber is dried in a controlled way to reduce the twisting, shrinking, and movement that can happen as wet lumber dries out on your deck. We also use KDAT that is pre-stained brown, so the framing looks clean and finished from the start.
This is a huge benefit for second-story decks or any elevated build where you can see the framing from below-your deck looks better from the patio, the yard, or through basement windows. It’s also a strong point of pride for us: Decks Unique is the only decking company on Long Island offering this. And it’s backed by a limited lifetime transferable warranty, which adds value if you ever sell your home.
Choosing the Right Decking Materials
Choosing between Trex and TimberTech usually comes down to the look you want, how you use your deck, and the level of “finished detail” you care about. Trex Enhance is a strong value choice, Select steps up the style and durability, and Transcend and Signature are for homeowners who want richer color and a more premium feel. TimberTech also offers multiple lines with great color options and a high-end appearance, especially when you want a deck that looks tailored to your home’s architecture.
Under the surface, framing matters just as much. That’s where our KDAT substructure stands out-straighter boards, a cleaner look, and less movement compared to standard framing lumber. If you’re not sure what fits your home, we’ll walk you through real samples and honest pros/cons, so your decision feels clear-not overwhelming.
Custom Features for Comfort, Style & Safety
The best decks aren’t just flat platforms-they’re comfortable outdoor rooms. We build in features that make your deck feel intentional and easy to live with. Want a place to set a drink when you’re talking with friends? A cocktail rail gives you that little ledge that everyone ends up using. Prefer a clean, open view of the yard? Cable railings can keep sightlines open while still protecting kids and guests. Looking for simple and classic? Vinyl railings offer a bright, clean finish that pairs well with many Long Island home styles.
Lighting is another game-changer. LED stair risers, post-cap lights, and soft, warm perimeter lighting help people move around safely while giving the deck a relaxed evening glow. It’s the difference between “we should head inside” and “let’s stay out another hour.”
And because Port Washington has a mix of flat coastal areas and gently rolling hills along the Long Island Sound shoreline, we design shade structures that make sense for your yard-whether that’s a pergola for filtered sun, a covered section for all-weather use, or a layout that creates shade naturally at different times of day.
Visit Our Commack Showroom
If you’re choosing between colors, railings, and decking types, seeing everything online only gets you so far. At our Commack showroom, you can walk on full-size deck displays, compare railing systems up close, and see lighting demos that show how your stairs and posts can glow at night. We’ll also lay out material samples so you can feel the texture and see the color in real light, including Trex and TimberTech options and traditional wood choices.
Port Washington homeowners often tell us the showroom visit makes decisions easier because you can compare everything side-by-side instead of guessing from photos. It’s also a convenient trip along major North Shore routes, and it’s worth it for the confidence you get. Bring photos of your yard and we’ll talk through layout ideas, elevations, and style details with a designer-so your plan feels solid before we ever schedule a build.
Awards & Professional Recognition
Awards matter in decking because they’re not based on one good job-they’re based on consistency, training, and proven results over time. When an industry group or top manufacturer recognizes a contractor, it usually means the company is building to higher standards, staying current on best practices, and taking customer experience seriously. Decks Unique earned these recognitions by doing the unglamorous stuff right: tight planning, clean installs, strong materials, and clear communication. For homeowners, these awards make it easier to choose confidently-because you’re not just taking someone’s word for it. You’re hiring a builder recognized by organizations like NARI, NADRA, Remodeler 500, Trex Platinum, TimberTech Pro, and the BBB.
NARI recognizes remodeling professionals who deliver quality craftsmanship and strong business practices. For you, it’s a sign you’re hiring a deck builder who treats your project like a real investment, not a quick weekend job.
NADRA focuses specifically on deck and railing excellence, including safety and construction standards. This matters because decks must be built right from the frame up-especially when stairs, railings, and elevation are involved.
Remodeler 500 highlights top remodeling companies based on performance and reliability. Homeowners benefit because it points to a company with the systems and experience to manage your job smoothly.
Trex Platinum status is earned by contractors who meet high standards with Trex products and installs. It’s a big deal because it can also unlock stronger labor coverage on qualifying lines when installed by Platinum builders.
TimberTech Pro recognition shows that the builder is trained and experienced with TimberTech’s systems. For homeowners, that means cleaner details, proper fastening, and a deck that looks “finished,” not patched together.
BBB Accreditation is tied to trust, responsiveness, and accountability. If something comes up, you want a company that stands behind the work and communicates clearly-this recognition supports that.
Our Workmanship & Product Guarantees
We build decks the way we’d want them on our own homes-clean lines, solid structure, and details that don’t get skipped. Decks Unique includes a lifetime workmanship guarantee, because the install matters just as much as the material you choose. If you’re installing Trex, qualified products include strong manufacturer coverage, and Trex also offers a 10-year labor warranty on Signature & Transcend when installed by Trex Platinum builders (which we are). Trex fade-and-stain warranties vary by line: 50 years for Signature/Transcend, 35 years for Select, and 25 years for Enhance Naturals/Basic. TimberTech products commonly include 25-50-year fade-and-stain warranties depending on the collection.
Prefer real wood? We back that too, including a lifetime decay guarantee on wood decks. And for the framing, our KDAT substructure includes a limited lifetime transferable warranty, adding long-term value and confidence in what’s supporting your deck.
Built for Port Washington: Local Engineering Considerations
Port Washington decks need more than good looks. Between changing seasons, coastal exposure, and the mix of flat areas and gentle hills near the Sound, the structure underneath has to be planned carefully. Our team considers soil, frost depth, and wind resistance so your deck feels stable, safe, and built to last-not just “built to pass.”
Soil & Footings
Port Washington properties can include Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay). We size and place footings so they’re stable in those conditions, and we install below the local frost line of 42 inches to reduce shifting as the ground freezes and thaws.
Wind & Uplift Protection
We build with wind in mind up to 120 mph, especially on elevated decks and open yards where gusts can push and pull on the structure. Reinforced connections and hurricane-rated hardware help tie the deck together so it acts like one strong system instead of separate pieces.
Permits & Inspections
In some cases, permits may be required, depending on the size, height, and scope of the project. We help guide the process with the Town of North Hempstead Building Department, including the typical documents, plan details, and inspection coordination so you’re not left guessing.
Composite vs Wood Comparison Table
| Category | Composite/PVC Decking | Natural Wood Decking |
|---|---|---|
| Everyday Maintenance | Usually wash-and-go; great for busy households and entertaining. | Needs periodic cleaning and typically staining/sealing to keep it looking fresh. |
| Look & Feel | Consistent color and finish; many modern and coastal styles. | Classic, warm character with natural grain and the option to customize with stain. |
| Comfort & Splinters | Smooth and splinter-free feel in normal use; good for bare feet. | Can splinter or roughen over time if not maintained. |
| Weather Stability | Designed to resist seasonal movement; great for changing Long Island weather. | More likely to expand/contract and show wear without regular upkeep. |
| Best For | Homeowners who want low upkeep and long-term visual consistency. | Homeowners who love traditional style, want flexibility in stain color, or need a budget-friendly option. |
How We Build Decks Designed to Perform for Years
A long-lasting deck starts with the details most people never notice-until they’re missing. We often use joist tape to help protect the tops of framing boards from trapped moisture where water tends to sit. At the house connection, we install ledger flashing to help direct water away from the home, which helps protect the structure behind the deck. For a polished look, many homeowners in Port Washington choose picture framing, which creates a clean border around the deck surface and gives the whole project a higher-end finish.
Fasteners matter too, especially in Nassau County conditions where moisture and coastal air can be tough on metal over time. Depending on the application, we use stainless or ceramic-coated fasteners for better corrosion resistance and a cleaner appearance. We don’t believe in one-size-fits-all building. We match the build method to your home, your yard, and your material choice-so the deck looks great now and holds up well as the seasons roll by.
Deck Pricing in Port Washington
Deck pricing isn’t just about square footage. Two decks that are the same size can land in very different price ranges based on the materials you choose, the style of railing, the number of stairs and landings, lighting, built-in seating, and whether the deck is low to the ground or elevated. Yard layout matters too-especially when we’re working around slopes, existing patios, or tight access between houses.
We’ll help you compare options clearly so you can choose what’s worth it for your home, not what’s “popular.” Financing is also 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 plans and paperwork with the Town of North Hempstead Building Department?
Yes. If your project needs drawings, application documents, or inspection coordination, we help guide the process with the Town of North Hempstead Building Department so it stays organized and predictable.
In Port Washington, are permits always required for a new deck?
Not always. In some cases, permits may be required based on things like deck height, size, and layout. We’ll review your project scope and help guide the permitting steps if they apply.
How fast can you build my deck?
Most projects are completed in 1-2 days. Larger or more complex builds (multi-level layouts, specialty rails, lots of lighting, or detailed stairs) can take longer, but we’ll give you a clear schedule before we start.
What’s the real difference between Trex, TimberTech, and PVC?
Trex and TimberTech are popular low-maintenance choices with a wide range of colors and styles. PVC is often chosen when homeowners want the easiest cleanup and strong resistance to staining. We’ll show you samples and help you choose based on how you’ll actually use the space.
Why do you recommend KDAT framing, especially for raised decks?
KDAT is kiln-dried framing lumber that we use because it stays straighter and cleaner as it seasons. It’s also pre-stained brown, which is a big visual upgrade when the underside of the deck is visible from the yard or patio.
