Custom Deck Design & Construction in Lake Grove, NY
Built to handle Suffolk County winters and made for those easy, shoes-off summer days outside.
Picture a quiet Lake Grove morning: coffee in hand, the sun just hitting the yard, and you’ve got a clean, sturdy deck that feels like a natural extension of your home. Later, it’s a spot for grilled dinners, kids doing homework at the table, or a calm corner with soft lighting when the evening cools off. That’s what we build at Decks Unique-decks that look sharp, stay comfortable, and don’t turn into a yearly maintenance headache. We’re a Long Island deck builder with real systems in place, from smart layout and drainage planning to clean finishes that hold up in Suffolk County 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 chasing paperwork. Homeowners also like that we’ve earned ratings like 5.0 on Google and 94% on Facebook-because a deck is only “beautiful” if it’s built right.

Transforming Outdoor Living for Lake Grove Homeowners
A great deck changes how you use your whole house. It turns “the backyard” into a real living space-one that works for quick breakfasts, family parties, and those nights when you’d rather stay home than fight restaurant waits. In Lake Grove, we build decks that match the way local homes are laid out-whether you want a simple step-down platform for everyday use or a larger entertaining space with room for a dining set, a grill zone, and a few loungers. You’ll feel it right away: more breathing room, better flow, and a place that makes the home feel bigger without adding a full addition.
We also keep the process easy. We help you choose the right materials for your goals-low upkeep, natural wood warmth, cooler feet in summer, or a specific color that ties into your siding and trim. We plan for safe stairs, solid railings, and proper water management so the deck stays comfortable and dependable year after year. And yes, speed matters too. Most decks are completed in just 1-2 days, so you’re not living in a construction zone for weeks.
When the work is done, Lake Grove “staycations” get a lot better: morning sun, afternoon shade, and that relaxed feeling of having a finished outdoor space you’re proud to show off.
Natural Wood Decking Choices
Some homeowners in Suffolk County still want real wood-and I get it. Wood has a warmth you can’t fake. Cedar is a popular choice for its natural character and lighter feel underfoot. Mahogany brings a rich, high-end look that’s hard to beat when you want that classic “resort” vibe. Pressure-treated lumber remains a strong option when budget matters, or when you want a solid, traditional deck that can be upgraded with nicer railings and lighting.
Here’s the honest part: our humidity, salty air, and sun can be tough on wood. If you choose wood, plan on regular cleaning and re-staining or sealing so it keeps that fresh look and resists surface wear. We’ll walk you through what that upkeep really looks like-no sugarcoating-so you can make the right call for your time and lifestyle.
Wood is often the best fit when you love the natural grain, you want a more classic look for an older home style, or you’re building a practical deck and want to put more of the budget into stairs, railings, or a great lighting plan.
Trex, TimberTech & PVC Decking Options
Composite and PVC decking are made for homeowners who want the deck to look great without spending weekends sanding and staining. These boards are designed to resist everyday problems like splintering, heavy fading, and the kind of staining that comes from cookouts and outdoor living. They also tend to stay more consistent over time-less cracking and less warping compared to typical wood boards-especially in the temperature swings we see across Suffolk County.
Trex is a favorite because it offers clear “levels” depending on the look and performance you want. Trex Signature and Trex Transcend are premium options with a high-end finish and strong long-term protection. Trex Select is a solid mid-level choice when you want a great look and dependable performance without going all the way to the top tier. Trex Enhance (including Naturals and Basics) is often picked when homeowners want low maintenance at a more approachable price point. TimberTech also has excellent lines, with a wide range of colors and textures, and homeowners love the realistic wood-like styles.
PVC decking is another option some Lake Grove homeowners choose, especially when they want a very stain-resistant surface and a board that handles moisture extremely well. It can be a smart fit near pools, hot tubs, or high-spill entertaining areas.
Warranty coverage varies by product line, but many composites and PVC options fall into fade-and-stain warranty ranges of roughly 25-50 years. And if you still love the feel of natural wood, we can absolutely build that too-we’ll just help you plan it the right way.
Why We Use KDAT Lumber for the Substructure
KDAT lumber is a big deal if you care about how your deck looks underneath and how it stays straight over time. KDAT means the framing wood is kiln-dried, and we use it pre-stained brown. That’s a huge benefit on second-story decks where the framing is visible from the yard-suddenly the underside looks finished, not like raw construction lumber. Because it’s dried more thoroughly, it tends to stay more stable, with less twisting and movement as it seasons. The end result is a cleaner-looking structure and a deck that feels tighter as the years go by.
Decks Unique is the only decking company on Long Island offering this, and it comes with a limited lifetime transferable warranty-another layer of confidence for homeowners who plan to stay put or protect resale value.
Choosing the Right Decking Materials
If you want the “best of the best” look and long-term peace of mind, Trex Signature or Trex Transcend are often the first place we start. If you’re balancing budget and performance, Trex Select and Trex Enhance can be a great match. TimberTech has excellent options too, especially for homeowners focused on a very natural, wood-like appearance and a wide color selection.
Just as important as the surface boards is what’s holding everything up. KDAT framing outperforms standard framing in appearance and stability, especially on elevated builds where the underside is part of what you see every day. We’ll guide you through the pros and cons in plain language, show you samples, and help you choose a combination that fits your home, your maintenance tolerance, and how you actually plan to use the space.
Custom Features for Comfort, Style & Safety
A deck should feel finished-like it belongs with the house-not like a plain platform. Railings make a huge difference in both safety and style. Cocktail railings give you a wide, comfortable “ledge” for drinks and small plates when friends are over. Cable railings are great when you want a clean, open view. Vinyl railings are a popular choice for homeowners who want a crisp look with very low upkeep.
Lighting is where the deck really becomes a lifestyle upgrade. LED stair riser lights make steps safer at night without blasting the whole yard with harsh brightness. Post-cap lights add a soft glow that feels inviting when you’re outside after dinner. With the right plan, you can walk, grill, and relax comfortably-no phone flashlight needed.
We also build shade solutions that make sense for Long Island sun and summer heat. Whether it’s a pergola-style structure, a privacy wall for wind, or a dedicated lounge area that gets the best afternoon shade, these add-ons make the deck more usable for more hours of the day-and they make the space feel intentional and high-end.
Visit Our Commack Showroom
If you’re serious about building a deck, seeing materials in person makes decision-making so much easier. Our Commack showroom is set up so you can walk full-size deck displays, compare railing systems side-by-side, and actually see lighting demos instead of guessing from a tiny picture online. We’ll show you a range of Trex and TimberTech options, plus real wood selections, so you can feel the textures, compare colors in natural light, and understand what “low maintenance” really looks like.
Homeowners from Lake Grove stop in all the time because it’s a convenient drive along major routes, and it saves you from second-guessing. You can meet with a designer, review layout ideas, and talk through details like stairs, rail height, and how to create a clean transition from your back door. It’s relaxed, hands-on, and it builds confidence before we ever break ground.
Awards & Professional Recognition
Awards matter in decking because they’re not handed out for good intentions-they’re earned through real results: strong design, consistent craftsmanship, and a track record of happy homeowners. In our world, recognition is tied to details that actually protect your investment, like proper structure, clean finishing, and following best practices. Decks Unique has been recognized by top industry groups and partners because we build the right way, train our teams, and stay accountable on every job. For homeowners, these awards remove a lot of guesswork. You’re not just hoping you hired the right contractor-you’re choosing a company with proven standards backed by respected organizations like NARI, NADRA, Remodeler 500, Trex Platinum, TimberTech Pro, and BBB.
NARI recognizes remodeling excellence and professionalism. For homeowners, it’s a sign that your contractor is committed to quality work and proper project management-not shortcuts.
NADRA is a leading organization focused on deck safety and best practices. This matters because your deck isn’t just about looks-it needs to be built to perform and protect your family.
Remodeler 500 highlights companies with consistent production, strong customer service, and proven reliability. For you, that means a builder with real systems-scheduling, communication, and follow-through.
Trex Platinum is reserved for experienced installers who meet strict standards. Homeowners benefit through better planning, cleaner details, and access to labor coverage on qualifying Trex lines.
TimberTech Pro recognition reflects training and experience with TimberTech products. That helps ensure your deck is installed the way the manufacturer intends for long-term performance.
BBB Accreditation signals a commitment to honest business practices and customer care. It’s a layer of trust that matters when you’re investing in a major home upgrade.
Our Workmanship & Product Guarantees
We stand behind our builds with a Decks Unique lifetime workmanship guarantee, because the install quality is just as important as the boards you choose. On qualifying projects, Trex offers a 10-year labor warranty for Signature & Transcend when installed by Trex Platinum builders. Trex also offers fade and stain warranties that vary by line: Signature/Transcend 50-year, Select 35-year, and Enhance Naturals/Basic 25-year. TimberTech offers fade and stain warranty coverage that typically ranges from 25-50 years depending on the product you select.
If you choose natural wood, we include a wood deck lifetime decay guarantee. And for our KDAT framing, there’s a limited lifetime transferable warranty. We’ll explain what applies to your exact material choices so you know what protection you’re getting and how to keep your deck looking its best.
Built for Lake Grove: Local Engineering Considerations
On Long Island, a deck that “looks good” isn’t enough. In Lake Grove and across Suffolk County, we build for real-world conditions: seasonal freeze/thaw, soaking rains, summer humidity, and strong winds that can show up fast. Our planning focuses on stability, drainage, and connections that stay tight over time, so your deck feels solid and stays that way.
Soil & Footings
In the Lake Grove area, soil conditions can vary from yard to yard, and Suffolk County winters bring freeze/thaw cycles that can shift shallow supports. We size and place footings to sit deep enough for stability, helping prevent settling that can lead to bouncy boards, uneven stairs, or railings that feel loose over time.
Wind & Uplift Protection
Even inland neighborhoods feel the effects of coastal weather systems on Long Island, and sudden gusts can put stress on elevated structures. We use reinforced connections and hurricane-rated hardware where appropriate, so the deck is tied together as a system-helping it stay secure when wind tries to lift or rack the frame.
Permits & Inspections
In some cases, permits may be required depending on height, size, and how the deck connects to the home. Decks Unique helps guide the process with . so you know what to expect, what gets submitted, and how inspections are scheduled without the usual headaches.

How We Build Decks Designed to Perform for Years
Our best decks aren’t “lucky builds”-they’re built from a repeatable process that focuses on water control and long-term strength. We often use joist tape to help protect the tops of framing members where water tends to sit. At the house connection, we use proper ledger flashing to help keep moisture from sneaking behind the deck and into the structure of your home. For a cleaner, more finished appearance, many homeowners choose picture framing, which creates a crisp border around the deck surface and elevates the overall look.
Fasteners matter on Long Island. Depending on the application, we use stainless or ceramic-coated fasteners that are better suited for Suffolk County moisture and seasonal weather. The goal is simple: fewer callbacks, fewer squeaks, fewer ugly stains, and a deck that stays tight and good-looking through year after year of real use.
Deck Pricing in Lake Grove
Deck pricing isn’t just about square footage. Material choice plays a big role (wood vs. composite vs. PVC), and so do the details that make a deck feel “custom.” Railings, stair design, deck height, picture framing, lighting, and any elevation changes in the yard all affect labor and layout. Even access to the backyard can change the plan and timeline.
We’ll give you clear options so you can control the budget without sacrificing the parts that matter most. Financing is available for qualified homeowners, and we’ll help you map out a build that fits your goals now and adds value long-term.
Frequently Asked Questions
Do you build decks that fit the style of homes in Lake Grove neighborhoods?
Yes. In Lake Grove we see a mix of classic colonials, ranch-style layouts, and updated homes, and each one benefits from a different deck footprint. We design around how you enter the yard, where you’ll grill, and where you want seating so it feels natural-not like an afterthought.
How fast can my deck be built once we finalize the plan?
Most projects are completed in 1-2 days. Larger or more complex builds can take longer, but we’ll set expectations up front so you can plan around deliveries, access, and family schedules.
In Lake Grove, do I need a permit to replace or build a deck?
In some cases, permits may be required depending on factors like size, height, stairs, and how the deck attaches to the home. We help guide the process so you’re not stuck guessing what needs to be filed or when an inspection should happen.
What’s the biggest reason you recommend KDAT framing?
KDAT is kiln-dried and pre-stained brown, which looks dramatically better on elevated decks where you can see the framing from below. It also tends to stay straighter over time, helping the deck feel tighter and look cleaner as seasons change.
If I’m choosing between Trex, TimberTech, and PVC, what do most homeowners pick?
Many homeowners choose Trex or TimberTech for the balance of comfort, appearance, and low upkeep. PVC is often chosen when maximum stain resistance and moisture performance are top priorities, like near pools or high-traffic entertaining areas. We’ll show you samples and explain the differences in plain English.
