Built to handle Nassau County cold snaps and summer heat, so your outdoor space feels easy, comfortable, and dependable year after year.
Picture a quiet morning with coffee outside, the air still cool, and the backyard finally feeling like part of the house.

Transforming Outdoor Living for Lake Success Homeowners
A great deck changes how you use your home. It becomes the place where dinner feels less rushed, where kids spread out without taking over the kitchen, and where you can sit outside after a long day and actually unwind. We often design Lake Success decks with “real life” in mind: a dining zone that fits a full table, a step-down bench area for conversation, and stairs that land naturally where you already walk. For Colonials, we can create a balanced, symmetrical look that feels like it was always part of the home. For Split-Level homes, we focus on smooth transitions-so you’re not dealing with awkward steps or tight landings. For Ranch-style houses, we love building wider decks that extend the main level and make the yard feel larger.
Life here moves fast, especially with quick access to Lakeville Road and the Northern State Parkway. A well-built deck gives you that staycation feeling without planning anything complicated-grill nights, birthday parties, or a calm Sunday with a book. And because we build decks every day, the process is efficient: most decks are completed in just 1-2 days. You get a cleaner jobsite, less disruption, and a finished space you can enjoy right away.
Natural Wood Decking Choices
There’s something honest and classic about real wood under your feet. Many Lake Success homeowners still love the warmth and character you only get from natural boards-especially when the deck is meant to complement traditional architecture and landscaping. We build with popular wood options like cedar for its natural beauty, mahogany for its rich, upscale look, and pressure-treated lumber when budget and strength are the priority. Each has its own style and feel, and we’ll help you choose the one that matches your home and how you plan to use the space.
Wood does require care, and we’ll be straight with you about that. Nassau County humidity, summer storms, and everyday foot traffic mean wood performs best when it’s cleaned and protected on a regular schedule. The payoff is a deck with natural charm that can be refreshed over time. Homeowners typically choose wood when they want a traditional look, when they enjoy maintaining their home, or when they want a strong value option without giving up the “real wood” experience.
Trex, TimberTech & PVC Decking Options
If you want the look of a beautiful deck without spending your weekends sanding and staining, composite and PVC decking are usually the answer. These boards are engineered to resist the common problems that frustrate homeowners-splinters, frequent re-staining, and the uneven aging you often see with basic lumber. Composite decking (like Trex and TimberTech) is made to feel solid underfoot, stay more stable as seasons change, and clean up easily with normal household care. Many families love it because it’s comfortable for bare feet and it keeps that “new deck” look longer.
Trex offers several lines, and we guide you based on what matters most to you-best overall performance, specific colors, or the strongest long-term protection. Trex Signature and Trex Transcend are popular for homeowners who want a premium look and top-tier coverage, while Trex Select and Trex Enhance are great when you want quality and comfort at a different price point. TimberTech also gives you excellent choices, including collections known for richer color options and high-end styling. If you want a deck that feels especially sleek and is extremely easy to maintain, some homeowners prefer PVC decking because it’s built to handle moisture and mess with minimal fuss.
Warranty coverage varies by product line, but many composite and PVC options come with fade-and-stain coverage ranges that typically fall between 25 and 50 years. If you love the idea of low upkeep but still appreciate the warmth of traditional materials, we can also design projects that blend composite decking with wood details where it makes sense.
Why We Use KDAT Lumber for the Substructure
KDAT is pressure-treated framing lumber that’s kiln-dried, and we take it a step further by using KDAT that is pre-stained brown. That means the framing is more stable, less likely to twist as it dries out, and it simply looks cleaner during and after construction. This matters a lot on second-story decks where you can see the structure from below-your deck doesn’t just look great on top; it looks finished underneath too. It’s one of those details homeowners notice every day when they walk out back.
It’s also a real point of pride: Decks Unique is the only decking company on Long Island offering this KDAT substructure option. And for added peace of mind, KDAT includes a limited lifetime transferable warranty.
Choosing the Right Decking Materials
Picking decking isn’t just choosing a color-you’re choosing how your deck will feel, how it will age, and how much time you’ll spend caring for it. Trex Signature and Trex Transcend are premium options for homeowners who want a higher-end look and strong long-term protection. Trex Select hits a nice balance for many families, and Trex Enhance is a popular value choice that still delivers a comfortable, low-maintenance surface. TimberTech also offers multiple collections, and we’ll help you compare the look, traction, and overall feel side-by-side.
Just as important as the surface is what’s underneath. Our KDAT framing outperforms standard framing by staying straighter and looking more finished-especially on raised decks. We’ll walk you through the best match for your home, your budget, and how you actually plan to use the space.
Custom Features for Comfort, Style & Safety
The best decks don’t feel “added on.” They feel like an outdoor room, and the right features make that happen. For railings, some Lake Success homeowners like a cocktail rail because it gives you a comfortable ledge for a drink or a plate at parties. Cable railings are chosen when you want a clean, open view, while vinyl railings are great when you want a crisp, bright look with easy upkeep. We’ll help you pick a style that fits your home’s architecture and how much privacy you want.
Lighting is another game-changer. LED stair risers improve safety at night, and post cap lights create that soft glow that makes evenings outside feel calm and welcoming. Add subtle ambient lighting around seating and you’ll actually use the deck more-without harsh floodlights. We also build shade structures that make sense for generally flat to gently rolling suburban terrain, so you can create comfortable cover for dining, lounging, or a grill zone. The result is a deck that looks sharp, feels safe, and stays comfortable from afternoon sun to late-night conversation.
Visit Our Commack Showroom
If you’re serious about building a deck, seeing materials in person makes the decision easier. At our Commack showroom, you can walk on full-size deck displays, compare railing systems at real height, and see lighting demos that show how your deck will look after sunset. We’ll also lay out Trex and TimberTech options side-by-side, along with PVC choices and real wood selections, so you can touch the textures and see true color in different lighting.
Homeowners from Lake Success often stop in because it’s a convenient trip along major North Shore routes, and it saves you from guessing based on tiny samples. You’ll be able to sit down with a designer, review layout ideas, talk through stairs and railings, and leave with a plan that feels clear. It’s one of the fastest ways to build confidence before you build the deck.
Awards & Professional Recognition
Awards matter in decking because they’re not handed out for “pretty pictures.” They’re earned through consistent craftsmanship, strong customer experience, and building the right way over and over again. When a company is recognized by industry leaders, it usually means their process is solid: design, planning, installation, and follow-through. Decks Unique has earned recognitions that reflect the work we do every day-clean builds, dependable scheduling, and details that hold up in real Long Island weather. For homeowners in Lake Success, these awards help take the guesswork out of hiring. You’re not just hoping the crew is good-you’re choosing a contractor with proven consistency across many projects, many seasons, and many inspections.

Our Workmanship & Product Guarantees

Product protections depend on what you choose, and we’ll review the exact coverage with you before you decide.

Trex fade and stain warranties vary by line: Signature/Transcend carry 50-year coverage, Select carries 35-year coverage, and Enhance Naturals/Basic carries 25-year coverage. TimberTech offers fade and stain warranties that generally range from 25 to 50 years depending on the collection.

Built for Lake Success: Local Engineering Considerations
Decks in Lake Success need more than good design-they need the right structural planning for local soil, seasonal freezing, and coastal-style wind events that can push and pull on outdoor structures. We build with clear engineering priorities so your deck feels steady, drains correctly, and stays tight through the years.
Soil & Footings
Lake Success properties can include 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 size and place footings to reach the local 42 inches frost line so the structure is supported below the zone where freezing and thawing can shift the soil.
Wind & Uplift Protection
Designing to handle up to 120 mph conditions means we pay attention to connections, not just boards. We use reinforced attachment points and hurricane-rated hardware where needed, helping the deck resist uplift and racking forces that can occur during major storms.
Permits & Inspections
In some cases, permits may be required, and the rules can vary based on height, placement, and scope. We help guide the entire process with the Incorporated Village of Lake Success Building Department, including the right drawings and scheduling inspections so you’re not left figuring it out alone.
Composite vs Wood Comparison Table

| Comfort | No splinters and a more uniform walking surface. | Natural texture; can splinter as it ages if not maintained. |
| Weather Resistance | Built to resist common moisture issues and seasonal movement. | Performs well when maintained; can show wear faster in humid conditions. |
| Best Fit For | Busy homeowners who want low upkeep and long-term color stability. | Homeowners who love the traditional look or want a specific budget approach. |
How We Build Decks Designed to Perform for Years
A deck can look great on day one and still disappoint if the “hidden” details are skipped. Our builds focus on the parts you won’t see every day-but you’ll feel the difference over time. We commonly use joist tape to help protect the top of the framing from trapped moisture, which can extend the life of the structure. At the house connection, we use proper ledger flashing to help direct water away from the home, reducing the chance of water getting where it shouldn’t. For finishing, many homeowners love picture framing because it gives the deck a clean, intentional border that looks like custom carpentry instead of a basic platform.
Fasteners matter on Long Island. Depending on your project and material choices, we may use stainless or ceramic-coated fasteners to help resist corrosion in Nassau County conditions. We don’t rely on one “cookie-cutter” approach-your layout, sun exposure, and elevation all influence the best build plan. The goal is simple: a deck that stays tight, drains well, and looks sharp season after season.
Deck Pricing in Lake Success
Deck pricing isn’t just about square footage. The material you choose (wood vs composite vs PVC), the railing style, the number of stairs and landings, and the height of the deck all affect the final cost. Even on generally flat suburban lots, small elevation changes can influence framing, steps, and how the deck connects to your home. Custom features like lighting, built-in seating, and shade structures also change the scope-often in a way that dramatically improves everyday enjoyment.
We’ll walk you through options clearly, line by line, so you can make smart choices without feeling pressured. Financing is available for qualified homeowners.
Frequently Asked Questions
Do you handle projects that need approvals through the Incorporated Village of Lake Success Building Department?
Yes. In some cases, permits may be required depending on things like deck height, stairs, and how the structure is attached. When approvals are part of the job, we help guide the process-drawings, submissions, and inspection coordination-so it feels organized instead of stressful.
My home is a Split-Level-can you design the deck so the stairs and landing don’t feel awkward?
Absolutely. Split-Level homes often need smarter transitions between doors, grade, and patio areas. We design step placement, landing size, and railing layout so the deck feels natural to walk on, not like you’re “climbing down” into the yard.
How fast can you build a deck in Lake Success once the design is set?
Most projects are completed in 1-2 days. Larger or more complex builds can take longer, but our process is designed to keep the job moving and the property as clean and usable as possible.
Is KDAT framing really worth it for a second-story deck?
If the underside of the deck is visible, KDAT is a big upgrade. Because it’s kiln-dried and pre-stained brown, the framing tends to stay straighter and looks much more finished-so you don’t have that raw, blotchy look underneath.
Should I choose Trex, TimberTech, PVC, or wood for a backyard that gets a lot of sun?
It depends on your priorities. Many homeowners choose Trex or TimberTech for low upkeep and strong long-term color protection, while PVC can be a great fit when you want an especially easy-to-clean surface. If you love a traditional look, wood can still be the right choice-you’ll just want to plan for routine maintenance to keep it looking sharp.
