Custom Deck Design & Construction in Locust Valley, NY
Designed for Nassau County cold snaps and built to shine through those easy, barefoot summer weekends outside.
Picture a quiet morning with coffee in hand, sunlight coming through the trees, and a clean, sturdy deck waiting right outside your back door. That’s what we build for Locust Valley homeowners-outdoor space that feels like a real part of the home, not an afterthought. Whether you live in a classic Colonial with a big backyard, a cozy Cape that needs better flow, or a High Ranch where elevation matters, a custom deck makes everyday life simpler and more fun. It becomes the place for family dinners, after-school snacks, and low-key evenings with soft lighting and a cool breeze. We build throughout Locust Valley, Lattingtown, and Cove Neck, and we keep the process calm and organized-from design choices to material selection and scheduling. And in some cases, permits may be required; if they are, we help guide the process with the Town of Oyster Bay Building Division so you’re not stuck chasing paperwork. Homeowners also find comfort in our reputation, with ratings like 5.0 on Google and 5.0 on Houzz, because trust matters when your home is on the line.

Transforming Outdoor Living for Locust Valley Homeowners
On the North Shore, outdoor living isn’t a trend-it’s a lifestyle. A well-planned deck gives you a spot to slow down and enjoy your home more often. Morning coffee feels different when you can step out to a clean, solid surface with room for a small table and two chairs. Weeknights get easier when grilling doesn’t mean balancing plates on the back steps. And when friends stop by, you’ll actually have space for everyone to spread out without crowding the kitchen.
We design decks that match the lines of Colonials, Capes, and High Ranches, so the deck looks like it belongs there. For a Colonial, that might mean a wide entertaining platform with a railing style that feels traditional. For a Cape, it may be a slightly smaller deck with smart stairs and a landing that makes the yard feel bigger. For a High Ranch, we focus on safe stairs, steady framing, and a clean look from below.
Locust Valley homeowners also like how a deck turns “running errands” into “staying put.” Instead of heading out, you can enjoy your own space-especially after driving along Forest Avenue or Lattingtown Road and realizing you’d rather be home. And here’s a big stress-reliever: Most projects are completed in 1-2 days, so you’re not living in a construction zone for weeks.
Natural Wood Decking Choices
Wood decking still has a special feel that many homeowners love. It’s warm underfoot, it looks natural next to landscaping, and it fits older homes beautifully. For Locust Valley properties, we often build with cedar, mahogany, or pressure-treated wood depending on the look you want and how you plan to use the space.
Cedar is a favorite for its classic color and lighter feel. Mahogany brings a richer, upscale look that pairs well with higher-end exteriors and detailed trim. Pressure-treated wood can be a smart choice when budget matters and you want a strong, dependable deck that can be stained to match your home.
We’re also straight with you about upkeep. In Nassau County humidity and salty air near the coast, wood needs routine care-cleaning, checking fasteners, and re-staining when the time is right. Some homeowners enjoy that “hands-on” ownership. Others prefer low-maintenance boards and would rather spend weekends relaxing than maintaining. Either way, we’ll help you choose wood for the right reason: style, tradition, or cost-not guesswork.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are popular in Locust Valley because they make outdoor living easier. These boards are designed to handle sun, rain, and everyday mess without constant sanding or staining. For busy families, that’s a big win-wipe it down, hose it off, and get back to enjoying it.
Trex decking is one of the most requested options because it offers a strong balance of comfort, color choices, and low upkeep. Many homeowners compare Trex lines based on look and long-term value. Trex Signature and Trex Transcend are premium picks for deeper color and a more refined finish, while Trex Select and Trex Enhance are great when you want a beautiful deck with a tighter budget. TimberTech is another excellent choice, especially for homeowners who want certain color blends, board styles, and matching accessories that fit a specific design goal.
If you want the “cleanest” maintenance routine, PVC decking is worth a look. PVC boards are made to resist moisture and stains extremely well, which helps in shaded areas or near pools and outdoor dining zones. Many homeowners choose PVC when they want the lightest upkeep possible and a crisp, consistent look.
Warranty coverage varies by product line, but in general you’ll see fade-and-stain coverage ranges that run roughly from 25 years up to 50 years depending on the brand and collection. We’ll walk you through those options in plain English. And if your heart is set on a natural look, we’ll also compare these choices against real wood so you can decide with confidence.
Why We Use KDAT Lumber for the Substructure
Your deck is only as good as the frame holding it up. That’s why we offer KDAT lumber for the substructure. KDAT means the lumber is kiln-dried, which helps it stay straighter over time, and we use it pre-stained brown so it looks finished and clean. This is a game-changer for second-story decks, where you can see the framing from below-no “raw construction” look when you’re sitting on the patio underneath.
Because it’s dried and treated the right way, KDAT is less likely to twist, shrink, or look blotchy as it ages. The result is a tighter, more polished build. Decks Unique is the only decking company on Long Island offering this option, and it comes with a limited lifetime transferable warranty, which adds real value if you ever sell your home.
Choosing the Right Decking Materials
Choosing decking isn’t just picking a color-it’s picking how you want to live outside for years. Trex Signature and Transcend are premium options for homeowners who want top-tier style and long-term confidence. Trex Select is a strong middle-ground, and Trex Enhance is a smart value choice when you want the composite look with an easier budget. TimberTech offers its own range of collections, including higher-end options and great mid-level choices that homeowners often select for specific color blends and matching railings.
We also help you look past the surface boards. A deck with KDAT framing can outperform standard framing in appearance and stability, especially on elevated projects where the underside is visible. If you’re not sure what fits your home and how you’ll use the space, we’ll guide you through it step by step and make sure the final plan feels right.
Custom Features for Comfort, Style & Safety
Details are what turn a basic platform into a space you actually want to use every day. Railings are a big part of that. Cocktail railings create a wide top “shelf” for drinks and small plates during get-togethers. Cable railings are great when you want a more open view across the yard. Vinyl railings are a clean, classic choice for low upkeep and a bright, tidy look.
Lighting is another upgrade that changes everything. LED stair riser lights help you see each step clearly at night, and post cap lights add a soft glow that makes the whole deck feel inviting-perfect for winding down after dinner. Instead of blasting a bright floodlight, you get that calm, warm evening feel that makes outdoor time last longer.
For shade and comfort, we design options that work with Locust Valley’s gently rolling, near-coastal terrain. That might mean a pergola for filtered light, a roofed section for all-weather coverage, or a layout that tucks seating into a more sheltered spot. These features don’t just look good-they make the deck safer, cooler, and more enjoyable for everyone.
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 can walk on full-size deck displays, compare railing systems side-by-side, and see lighting demos that show how your stairs and posts will look after sunset. We also keep material samples on hand, including popular Trex and TimberTech options and real wood selections, so you can feel the texture and see the color in person-not just on a screen.
Many homeowners from Locust Valley visit because it’s a straightforward drive along major North Shore routes, and it saves time in the decision-making process. Instead of guessing, you can sit with a designer, review layout ideas, talk through budget priorities, and leave with a clearer plan. It’s a relaxed, professional environment, and it helps you choose with confidence.
Awards & Professional Recognition
In decking, awards aren’t about bragging rights-they’re about proof. They show that a company can deliver quality work again and again, not just on one lucky project. Recognitions from groups like NARI and NADRA point to real craftsmanship and solid business practices. Industry lists like the Remodeler 500 highlight consistency and operational strength. And programs like Trex Platinum and TimberTech Pro show that our crews meet strict standards set by the manufacturers. Add BBB accreditation, and you get a clearer picture of how we treat customers before, during, and after the build.
NARI
Recognition from NARI matters because it reflects professional remodeling standards and strong project execution. For homeowners, it’s reassurance that your deck is being built with care, planning, and accountability.
NADRA
NADRA focuses specifically on the deck and outdoor living industry. This recognition signals that we take best practices seriously-from safe structures to clean finishing details you’ll notice every day.
Remodeler 500
Being listed shows we’re not a “pop-up” contractor. It points to a stable company with the staff, systems, and experience to manage your project smoothly and professionally.
Trex Platinum
Trex Platinum status is earned, not bought. It tells homeowners we’re trusted to install Trex the right way, and it can also connect you to stronger labor coverage on qualifying product lines.
TimberTech Pro
This program recognizes contractors who install TimberTech products to manufacturer standards. For you, that means better detailing, cleaner finishing work, and fewer headaches during the build.
BBB Accreditation
BBB accreditation is about trust and follow-through. Homeowners value it because it reflects how a company handles communication, service, and customer concerns over time.
Our Workmanship & Product Guarantees
We stand behind what we build. Decks Unique includes a lifetime workmanship guarantee, so you can feel confident that the installation is backed long after the tools are packed up. Product coverage depends on the brand and line you choose. Trex offers a 10-year labor warranty on Signature and Transcend when installed by Trex Platinum builders. Trex also offers fade and stain warranties that range by product: 50 years (Signature/Transcend), 35 years (Select), and 25 years (Enhance Naturals/Basic). TimberTech offers fade and stain warranties that generally range from 25 to 50 years depending on the collection. For homeowners choosing natural lumber, our wood decks include a lifetime decay guarantee. And for the frame, KDAT lumber includes a limited lifetime transferable warranty, which helps protect the value of your investment.
Built for Locust Valley: Local Engineering Considerations
Beautiful decks are great, but on the North Shore they also need to be built for the ground, the weather, and the local review process. From gently rolling, near-coastal terrain to changing soil conditions, we design each deck so it feels solid underfoot and stays that way. Our team looks at how water moves on your property, how the deck connects to the home, and how to build strong footings and connections that match local conditions.
Soil & Footings
Locust Valley areas can include Sandy Loam, Silt Loam, and Clay (a dense mix of Sand, Silt, & Clay), and each one holds water and settles differently. We size and place footings to match the conditions and we dig to the local frost line of 42 inches so the deck has a stable base that resists seasonal movement.
Wind & Uplift Protection
With design wind speeds that can reach 120 mph, connections matter just as much as the boards you see on top. We use reinforced attachment points and hurricane-rated hardware where appropriate to help the deck stay tight and secure during strong storms and gusty coastal weather.
Permits & Inspections
In some cases, permits may be required, depending on the scope and details of your project. We help guide the process with the Town of Oyster Bay Building Division, including planning for inspections, so you’re not left guessing what comes next.
Composite vs Wood Comparison Table
| Category | Composite / PVC Decking | Natural Wood Decking |
|---|---|---|
| Everyday upkeep | Usually a simple wash keeps it looking sharp; no routine staining for most homeowners. | Needs periodic cleaning and re-staining/sealing to keep color and protect the surface. |
| Look & feel | Consistent color choices with a clean, finished look that stays stable. | Natural grain and warmth; a classic look that many homeowners love. |
| Best for | Busy schedules, outdoor dining, pool areas, and homeowners who want low maintenance. | Traditional style, specific wood aesthetics, or budget-driven builds (depending on species). |
| Long-term consistency | Designed to resist fading and staining; warranty ranges vary by brand and line. | Will weather naturally; can be refreshed with sanding and staining when needed. |
How We Build Decks Designed to Perform for Years
Great decks don’t happen by luck-they come from smart building habits that protect the structure. We often use joist tape on key framing areas to help shed water and reduce wear where boards and framing meet. At the house, we install proper ledger flashing to help direct moisture away from the connection point, which is one of the most important parts of the entire deck.
For finishing, picture framing is a popular upgrade that gives the deck a clean border and a more custom look, especially on composite builds. We also pay close attention to fasteners because coastal conditions can be tough on metal over time. Depending on your project and material choice, we may use stainless or ceramic-coated fasteners to help reduce rust and staining. The goal is simple: a deck that looks clean now and stays strong through the seasons, without cutting corners you can’t see.
Deck Pricing in Locust Valley
Deck pricing isn’t just about square footage. The final cost depends on the material you pick, the style of railing, the number of stairs, and how the deck sits on the property-especially with elevation changes that are common around gently rolling areas. Built-in features like lighting, seating, picture framing, and shade structures also affect the budget, but they can add a lot of comfort and daily value.
If you want to spread payments out, financing is available for qualified homeowners. The best way to get real numbers is to talk through your goals and let us design around them.
Frequently Asked Questions
Do you handle Town of Oyster Bay paperwork for Locust Valley projects?
Yes. In some cases, permits may be required, and when they are, we help guide the process with the Town of Oyster Bay Building Division. We’ll help you understand what’s needed for your specific deck and keep things moving so you’re not stuck in limbo.
How fast can you build a deck in Locust Valley?
Most projects are completed in 1-2 days. Larger designs, complex stairs, or specialty features can add time, but we’ll set expectations clearly before we start and keep the job site neat and organized.
My home is a High Ranch-can you make the underside of the deck look finished?
Absolutely. High Ranch decks are often elevated, which means the framing is easy to see. That’s one reason we offer KDAT framing that’s kiln-dried and pre-stained brown, so the structure looks cleaner and more “complete” from below.
What’s better for our area: Trex, TimberTech, PVC, or wood?
It depends on how you want to use the space. If low upkeep is the priority, Trex, TimberTech, and PVC are strong choices. If you love natural character and don’t mind periodic maintenance, cedar or mahogany can be beautiful. We’ll compare options based on sun exposure, foot traffic, and your budget.
We’re near Forest Avenue-will drainage or slope affect the design?
It can. Parts of Locust Valley have gently rolling terrain, and how water moves across the yard matters for footings, stairs, and the “feel” when you step outside. We design the layout to sit naturally on the property and avoid awkward transitions.
