Custom Deck Design & Construction in Mastic, NY
Made for Suffolk County winters, built for the kind of easy summer living you actually want to use every day.
Picture a quiet morning in Mastic: coffee in hand, bare feet on clean deck boards, and a little breeze moving through the yard before the day gets busy. A well-planned deck changes how you use your home. It gives you a real spot for dinners outside, a safe place for kids to play close by, and a comfortable “extra room” for weekend get-togethers. We build decks that look right on Long Island homes of all styles, from classic ranch layouts to capes and larger updated properties, and we build them to stay strong through wet springs, humid summers, and freezing weather. If your project falls into a category where approvals are needed, in some cases permits may be required, and we help guide the process so you’re not stuck chasing paperwork or guessing what inspectors want. Homeowners also trust us because our work consistently earns ratings like 5.0 on Google and 94% on Facebook, and because we focus on clean craftsmanship that stays low-maintenance and good-looking for the long run.

Transforming Outdoor Living for Mastic Homeowners
A deck should feel like a natural extension of the house, not a “platform you step onto.” In Mastic, we design decks that match how families really live: a dining zone that fits a table without feeling tight, a grill area with breathing room, and a lounging corner where you can read, talk, or just watch the yard as the sun drops. It’s the kind of space that turns regular nights into something better. Dinner tastes different outside. Conversations last longer under soft lighting. And you stop feeling like you need to “go out” to enjoy your weekends.
We also keep the build process simple. You’ll get clear options, honest recommendations, and a plan that respects your home’s layout. Most decks are completed in just 1-2 days, so you’re not living in a construction zone for weeks. That speed doesn’t happen by luck-it comes from solid planning, experienced crews, and using the right materials from the start.
For many Suffolk County homeowners, a deck is the easiest way to create a staycation setup: morning coffee outside, family dinners under the stars, and a clean, safe space for birthdays and summer holidays. Whether your home is modest or expansive, the goal is the same: build something you’ll use constantly, not something you only look at through the window.
Natural Wood Decking Choices
Natural wood has a warmth you can’t fake. If you love a classic look and don’t mind a little upkeep, wood can be a great fit for a Mastic backyard. Cedar is a popular choice when homeowners want a lighter, more natural appearance with a softer feel underfoot. Mahogany is chosen for its rich color and higher-end look, especially when the deck is a major focal point for the home. Pressure-treated lumber is the practical pick-strong, widely available, and often the best option when budget matters but you still want a sturdy, good-looking deck.
That said, we’re always straight with homeowners about maintenance. Suffolk County humidity, spring rains, and summer sun can wear finishes down. Wood typically needs periodic cleaning and re-staining or sealing to keep it looking sharp and to help prevent splintering and surface wear. If you like the idea of wood aging naturally, that can be part of the charm. If you want the “install it and forget it” lifestyle, we’ll likely steer you toward composite or PVC.
Many homeowners still choose wood for the tradition, the natural character, or the cost. Our job is to build it correctly so it drains well, stays strong, and feels solid for years.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are built for homeowners who want more time enjoying their deck and less time maintaining it. Instead of sanding and staining, you’re usually looking at simple cleaning. These boards are made to hold their shape better than many traditional wood options, and they’re designed to keep color longer under sun and weather.
Trex is one of the most requested choices we install in Mastic because it hits a great balance of comfort, strength, and low upkeep. Homeowners often compare Trex lines based on look, feel, and long-term protection. Higher-tier lines like Trex Signature and Transcend are chosen when you want deeper color, a more refined finish, and premium warranty coverage, while Trex Select and Enhance are popular when you want the composite benefits at a more budget-friendly level. Trex fade-and-stain warranty coverage ranges by product line, including 50-year coverage for Signature/Transcend, 35-year for Select, and 25-year for Enhance Naturals/Basic.
TimberTech is another excellent option, especially for homeowners who want a certain board style, color blend, or a specific surface feel. TimberTech also offers fade-and-stain warranty coverage that commonly falls in the 25-50-year range, depending on the product you choose.
Some homeowners prefer PVC decking when they want an even lower-maintenance surface and a board that handles moisture extremely well-great for areas that stay damp or shaded. If you love the natural look of wood, we can also design a hybrid approach or help you choose composite colors that feel warm and natural, not plastic.
Why We Use KDAT Lumber for the Substructure
KDAT is one of those upgrades you don’t always “see” at first-but you’ll appreciate it for years. KDAT lumber is kiln-dried and pre-stained brown, which means the framing underneath your deck looks cleaner and more finished from day one. That’s a huge deal on second-story decks where the underside is visible from the yard, patio, or windows. Because it’s dried in a controlled way, it’s also more stable than standard framing lumber, helping reduce twisting, shrinking, and the little movement that can cause waves or squeaks over time.
It’s also a true differentiator: Decks Unique is the only decking company on Long Island offering this type of substructure. And for peace of mind, KDAT comes with a limited lifetime transferable warranty.
Choosing the Right Decking Materials
Picking decking is easier when you compare it the right way-by how you live, not just by color. If you want the most premium Trex look and feel, many homeowners land on Trex Signature or Transcend. If you want strong performance with a step down in price, Trex Select is often a smart fit. Trex Enhance lines are great when you want composite benefits and a streamlined budget.
TimberTech also gives you excellent style options, and we’ll help you sort through the differences in board patterns, tones, and traction so you don’t second-guess the decision after it’s installed.
And don’t forget the frame. KDAT framing can outperform standard framing because it stays more stable and looks cleaner-especially important when your deck sits higher off the ground. We walk you through samples, explain what matters (and what doesn’t), and help you choose a combination that fits your home, your yard, and your maintenance comfort level.
Custom Features for Comfort, Style & Safety
A great deck isn’t just boards-it’s the details that make it feel like an outdoor living room. For railings, we can build a comfortable cocktail rail that gives you a place to set a drink or a plate. Cable railings are popular when you want a more open view and a modern look. Vinyl railings are often chosen for their clean style and easy upkeep.
Lighting is another upgrade that changes everything. LED stair riser lights help prevent trips at night, and post-cap lights create a soft glow that makes the whole yard feel calmer and more inviting. It’s the kind of lighting that feels perfect for a quiet evening outside-no harsh glare, just a warm, finished look.
For shade, we design structures that make sense for Long Island weather and real-life use: partial shade for afternoon sun, coverage for seating areas, and layouts that keep airflow moving so the space doesn’t feel trapped in summer humidity. Add built-in benches, planters, or a dedicated grilling zone, and your deck stops being “outside space” and starts being where everyone naturally gathers.
Visit Our Commack Showroom
If you’re choosing decking, railings, and colors from tiny samples, it’s easy to hesitate. That’s why we invite Mastic homeowners to visit our Commack showroom and see everything in person. You can walk on full-size deck displays, compare railing systems side-by-side, and see lighting demos that show what stair and post lighting really looks like after dark. We also have material samples for Trex and TimberTech, plus natural wood options, so you can feel the textures and see the color depth with your own eyes.
Many homeowners make the trip because it’s convenient and it saves time in the long run. Instead of guessing, you’ll get real answers from experienced designers, review layout ideas, and leave with a clearer plan. It’s a straightforward, low-pressure way to make confident choices-and it usually prevents expensive change-orders later.
Awards & Professional Recognition
Awards aren’t just wall decorations. In the decking world, they’re a sign that a company is consistent-showing up on time, building to a high standard, and standing behind the work year after year. Decks Unique has earned recognition through respected industry groups and programs because we take craftsmanship seriously, we keep improving our systems, and we build decks that look great and perform in real Long Island weather. For homeowners, these awards help remove doubt. You’re not just trusting a sales pitch-you’re choosing a team that’s been evaluated by pros, manufacturers, and industry organizations like NARI, NADRA, and more.

Our Workmanship & Product Guarantees
We believe a deck should feel solid now and years from now, which is why we back our builds with a Decks Unique lifetime workmanship guarantee. On the product side, warranty coverage depends on what you choose: Trex offers a 10-year labor warranty on Signature and Transcend when installed by Trex Platinum builders (which we are), and Trex fade-and-stain coverage ranges by line-50 years for Signature/Transcend, 35 years for Select, and 25 years for Enhance Naturals/Basic. TimberTech fade-and-stain warranties typically range from 25-50 years depending on the product.
For homeowners who choose wood, we also offer a wood deck lifetime decay guarantee. And because we’re serious about what’s underneath the boards, our KDAT framing option comes with a limited lifetime transferable warranty. We’ll walk you through the exact warranty documents for the materials you select so you know what’s covered and what maintenance is expected.
Built for Mastic: Local Engineering Considerations
Mastic decks need more than good looks-they need smart planning underneath. From footing stability to hardware choices that handle tough storms, we build with Suffolk County conditions in mind. Our process is designed to reduce stress: we verify key details, plan for drainage and movement, and keep the job organized so the finished deck feels solid, safe, and comfortable.
Soil & Footings
Suffolk County soil can vary from yard to yard, so we plan footings that match the conditions we’re building on and the loads your deck needs to support. We also account for local frost depth requirements so footings are set to help prevent seasonal shifting that can cause uneven boards or railing movement over time.
Wind & Uplift Protection
Mastic can see strong coastal storms and heavy wind events, so we use reinforced connections where it counts. That includes hardware and fastening methods designed to help resist uplift and racking, especially on elevated decks and railings where movement can become noticeable if corners are cut.
Permits & Inspections
In some cases permits may be required, depending on the scope, height, and how the deck ties into the home. Decks Unique helps guide the process from the start, including what plans may be needed, what details inspectors typically look for, and how to keep the timeline moving without surprises.

| Best fit for | Low-maintenance lifestyles, busy households, long-term color stability goals | Traditional style, natural appearance, or budget-focused builds |
How We Build Decks Designed to Perform for Years
Long-lasting decks come from the parts you don’t always notice. We often use joist tape to help protect the tops of the framing from water exposure, which can reduce the chance of moisture sitting where it shouldn’t. Where the deck connects to the house, we pay close attention to ledger flashing so water is directed away instead of sneaking behind the structure. Those details help protect both the deck and the home.
For a cleaner finished look, many homeowners choose picture framing, which creates a border around the deck surface and gives the whole project a more custom feel. We also select fasteners that make sense for Suffolk County conditions-often stainless or ceramic-coated options-so the hardware holds up better against moisture and seasonal swings. None of this is about “upselling.” It’s about building a deck that feels tight underfoot, looks sharp from every angle, and stays that way through years of real use.
Deck Pricing in Mastic
Deck cost isn’t just about square footage. Pricing is shaped by the material you choose (wood vs composite vs PVC), railing style, stair count, lighting, and whether the deck is low to grade or elevated with more framing and structural requirements. Even small layout changes-like wrapping stairs or adding a wide landing-can change labor and material needs.
We’ll help you price options in a clear way so you can decide what matters most: a larger footprint, premium boards, upgraded railings, or lighting that makes the space safer at night. Financing is available for qualified homeowners, and we’ll explain those options during your estimate.
Frequently Asked Questions
Do you build decks that match the style of older Mastic homes?
Yes. A lot of Mastic homes have simple, practical layouts, and a deck should feel like it belongs there-not like an add-on. We’ll match railing choices, colors, and proportions to your home so the finished deck looks intentional and balanced.
How fast can the deck be built once we approve the design?
After materials and scheduling are set, most projects are completed in 1-2 days. Larger layouts, complex stairs, or specialty features can add time, but we’ll give you a realistic timeline upfront so you can plan around it.
Will my deck need a permit in Mastic?
In some cases permits may be required based on the size, height, and how the deck ties into the home. We help guide the process, including what documentation may be needed and how to keep inspections from slowing the job down.
What’s the biggest difference you’ll feel between Trex, TimberTech, PVC, and wood?
Most homeowners notice upkeep first. Composite and PVC usually mean less routine maintenance, while wood brings a natural look but needs more care over time. We’ll show you real samples and help you choose based on how you want the deck to look and how much maintenance you’re comfortable doing.
Is KDAT framing really worth it if I’m not building a second-story deck?
It can be. KDAT is kiln-dried and pre-stained brown, so it tends to look cleaner and stay more stable than standard framing. On a higher deck, the visual benefit is obvious, but even on a lower deck it can help reduce twisting and keep the structure looking more finished when you can see underneath from the yard.
