Custom Decks Built on Solid Framing

A great deck starts underneath: correctly sized footings, solid framing, and proper ledger flashing where the deck meets your house. We build wood and composite decks that stay level, safe, and squeak-free for the long haul.

From simple platforms to multi-level decks with built-in benches and lighting, we design around how your family will actually use the space.

Wood or Composite, Your Call

Pressure-treated and cedar decks offer classic warmth, while composite decking trades a higher upfront cost for almost zero maintenance. We will price both for your project in a free estimate so you can decide with real numbers. Upgrading the house as well? We pair decks with Long Island window and door replacement on plenty of projects.

Deck Building From the Ground Up

A deck is framing first and decking second. We dig footings below the frost line, set the posts plumb, and bolt the ledger to the house with flashing behind it so water never finds the band joist. Wood or composite, the boards on top only look as good as the structure underneath. That structure is what we build.

Benny's spent over 10 years earning its name in Long Island roofing before we ever framed a deck, and the habits carry over. Flash every joint. Use hardware rated for treated lumber and salt air. Pull the permit. You get a free written estimate that spells out the framing, the decking, the railings, and the stairs, so nothing changes once the work starts.

Planning Your Deck

Trex, Composite, or Wood Deck: Which Is Better on Long Island, NY?

The deck decision comes down to budget today versus maintenance forever. Here is the honest comparison we give at every estimate.

Pressure-Treated Wood Value

Wood remains the most affordable way to build a quality deck, and pressure-treated lumber handles Long Island weather well when maintained. Lower upfront cost leaves budget for size and features.

Natural Wood Character

Real wood underfoot has a warmth and feel composite still imitates. Sanded, stained, or left to weather, a wood deck ages like part of the landscape.

Composite Low Maintenance

Composite decking erases the sanding, staining, and sealing cycle entirely. It costs more upfront and pays it back every season you spend relaxing instead of refinishing.

The Pros of Wood and Composite Decks

  • Footings below the frost line: Long Island decks need footings deep enough not to heave in winter. Ours are dug, poured, and inspected to code every time.
  • Hardware rated for treated lumber: Modern pressure-treated lumber corrodes ordinary steel. We use hot-dipped galvanized and stainless hangers and fasteners rated for it, plus salt air.
  • Permits and inspections handled: Decks require permits in nearly every Long Island town. We handle drawings, filing, and inspections so resale never becomes a problem.

The Cons of Wood and Composite Decks

  • Wood demands upkeep: Expect to clean and re-stain or seal every couple of years, forever.
  • Composite costs more today: The upfront premium is real, and it pays back over years, not months.
  • Hot underfoot: Dark composite in full sun runs hotter than wood.

What Should I Watch Out for When Building a Deck?

Undersized footings:
Decks fail at the ground first. Footing depth and diameter are code items, not suggestions.

Ledger flashing:
The number one deck failure is water where the deck meets the house. Flash it right or rot the band joist.

Permit-free builders:
A contractor who suggests skipping the permit is volunteering you for problems at resale and insurance time.

How Long Does a Deck Last on Long Island?

A pressure-treated wood deck lasts 15 to 20 years with maintenance on Long Island, and composite runs 25 to 30, so upkeep is where the difference lives. Wood or composite, a deck lives outside year-round. The care list is short:

  • Wash every spring: Soap and water for composite, a gentle wash before inspection for wood.
  • Re-stain or seal wood every two to three years: The finish, not the lumber, is what fights the weather.
  • Check hardware each spring: Lags, joist hangers, and railing bolts loosen with seasonal movement.
  • Keep board gaps clear: Debris-packed gaps trap water against the frame underneath.

What Kind of Deck Should I Build?

The best deck follows how your family will actually use it. Three shapes cover most Long Island, NY yards.

1. Ground-Level Platforms:
Clean, simple, and fast to build. The affordable way to turn a yard into a living space.

2. Elevated Decks With Stairs:
The classic for raised homes and sloped yards, with structure and railings doing serious work.

3. Multi-Level Outdoor Living:
Built-in benches, planters, lighting, and pergolas that turn a deck into the house's favorite room.

Do You Install Deck Railings and Handrails?

Yes, on new builds and on older Long Island decks alike. Deck railing installation is where shortcuts show first, so we anchor every post to the framing underneath, never just to the deck boards. That is why our railings feel solid on day one and stay solid after ten winters.

Trex Deck Railing Installation

We install Trex, TimberTech, vinyl, and cable railing systems to the manufacturer's spec so the warranty holds, with wood still the affordable standby.

Deck Stair Railing Installation

Stair railings and handrails get set at code height with a solid grip the whole run, because stairs are where a loose railing does real harm.

Replacing Deck Railings

If the frame under an older deck is sound, new railings can go on without rebuilding anything else. A free inspection tells you what the deck can take, and the price comes in a written estimate.

Can You Add a Roof or Screened Porch Over My Deck?

Yes, and it is the job where a roofing company earns its keep. A porch roof lives or dies where it ties into the house, and flashing that connection is our everyday work on Long Island.

Attaching a Roof Over a Deck

We check the framing and footings first, since a roof adds real weight, then frame the tie-in and flash it so water never reaches the wall. If your shingles are near the end, plan the porch alongside a Long Island roof replacement so both roofs age together.

Screened Porch Contractors

Screens, a ceiling, and a light turn a deck into a three-season room. We build screened and covered porches on new decks and on sound existing ones, priced in a written estimate.

Under deck drain system: On an elevated deck, a drainage layer between the joists catches water and sends it to a gutter, keeping the patio below dry and usable.

Do You Build and Replace Deck Stairs?

Yes. Building deck stairs is precision work, and it is where DIY projects go wrong most often. Rise and run are code numbers, not guesses, and every set we build lands on a solid footing with a handrail you can trust.

Attaching Stair Stringers to a Deck

Stringers hang from the frame on rated hardware, not nails driven into end grain. We cut pressure treated stair stringers to keep every step even, because the one odd step is the one people trip on.

Deck Stairs With Trex

Composite treads over treated stringers give you stairs that match a Trex deck and skip the refinishing cycle, with risers and fascia wrapped so nothing weathers gray.

Replacing Deck Stairs

Rotted stringers and loose treads are the most common failure we find on older Long Island decks. Stairs can usually be rebuilt without touching the deck above, and a free inspection settles it either way.

Do You Build Pool Decks and Above Ground Pool Decks?

Yes. We build wood and composite pool decks across Long Island, sized for wet feet, towels, and traffic. To be straight with you, we are carpenters, not a concrete crew, so coatings and pool deck resurfacing are not services we sell.

Above Ground Pool Deck Installation

When we build a deck around an above ground pool, the footings carry the deck on their own so no weight bears on the pool wall. Decking runs just under the top rail for a clean step-in, with a gated stair built to code.

Pool Deck Installation for In-Ground Pools

For in-ground pools we frame decks and surrounds that tie the pool into the yard, with slip-conscious decking, railings and gates where height requires them, and a written estimate before any work begins.

What Determines Deck Cost on Long Island?

Deck budgets are set by three choices you control, which makes this the most plannable project in the yard.

1. Size and Height:
Square footage drives framing and decking, and elevation adds structure, stairs, and railing runs.

2. Material Choice:
Pressure-treated, cedar, and composite span a wide band, trading upfront cost against maintenance forever.

3. Features:
Built-in benches, planters, lighting, and pergolas turn a platform into a room, priced feature by feature.

Every project gets a written, itemized estimate before any work begins, so the number you approve is the number you pay.

Do I Need a Permit to Build a Deck on Long Island?

An unpermitted deck is a discount coupon a future buyer's attorney gets to use against you, and an insurance question you do not want asked after a failure.

Our Advice: Permit every deck. We handle the paperwork and build to code, so inspection day is a formality and closing day is clean.

Why Does the Deck Builder You Choose Matter?

The Footing Risk:
Decks fail at the ground first. Undersized or shallow footings heave, sink, and rack the frame above.

The Ledger Risk:
The number one deck failure is water where the deck meets the house. Flash the ledger right or rot the band joist behind it.

Our Approach: Code-depth footings, flashed ledgers, and framing you can jump on for decades, with permits handled from application to final inspection.

How We Check the Work as We Go

Every deck job starts with us walking the site. We look at the grade, where the water runs, how the ledger will meet the house, and whether the rim joist behind it is sound. On rebuilds we crawl underneath and probe the posts and stringers, because rot hides where the sun cannot reach. Ten minutes under a deck tells us more than an hour on top of it.

During the build we keep checking our own work. Footings get inspected before concrete covers them. Joists get crowned the same direction so the floor stays flat. Railing posts bolt to the frame, not the deck boards, and stair stringers hang on rated hardware. The crew that fastens the last picture-frame board is the same one that dug the first footing, so nothing gets lost between trades.

A shingle blew off and I expected the runaround. Instead Benny's came out the next morning, fixed it, and didn't even charge me. That's how you earn a customer for life.

Quick response after a windstorm. They tarped the roof the same day and had it fully repaired that week. Lifesavers. I recommend Benny's to every neighbor.

Frequently Asked Long Island Deck Installation Questions

Are you deck builders on Long Island?

Yes. Deck building is one of our core exterior services at Benny's, alongside the roofing work Long Island knows us for. We build wood, Trex, and composite decks on code-depth footings with flashed ledgers, permits handled, and you get a written estimate before any work begins.

Do you install Trex and composite decking on Long Island?

Yes, Trex, TimberTech, and other composite lines, installed with the hidden fasteners and gapping the manufacturer specs so the warranty holds. Most composite builds take one to two weeks once framing starts. We price composite against pressure-treated wood in the same free written estimate so you decide with real numbers.

Do you install or replace deck railings and handrails?

Yes, on decks we build and on decks we didn't. Railing posts get anchored to the framing, not just the deck boards, which is the difference between a railing you can lean on and one that wobbles in a year. Wood, composite, vinyl, and cable options, all to code height, priced in a free written estimate.

Can you build a roof or screened porch over my deck?

Yes, and this is where hiring a roofing company pays off. The riskiest part of a roof over a deck is where it ties into the house, and flashing that connection is what we do all day. Covered decks and screened porches both get a written estimate with the structure and roof priced together.

Is my old deck worth repairing?

Yes. We replace boards, railings, stairs, and rotted framing, and we resurface sound wood frames with new decking. A free inspection tells you honestly whether repair or replacement is the smarter money, and the number comes in writing either way.

Can you replace rotted deck stairs and stringers?

Yes. Stairs are the most abused part of any deck, so stringers get sized, cut, and attached correctly, with code rise and run and solid handrails. While we're at it we can build in benches, lighting, or a pergola so the deck fits how your family actually uses it.

How much does a new deck cost on Long Island?

Cost comes down to size, height, material, and features like railings, stairs, and built-ins. Pressure-treated wood is the affordable end and composite costs more upfront but erases the refinishing cycle. Every project gets a written, itemized estimate before any work begins, so the number you approve is the number you pay.

Do you handle deck permits on Long Island?

Yes. Nearly every Long Island town requires a deck permit, and we handle the drawings, filing, and inspections as part of the job. An unpermitted deck becomes a problem at resale and insurance time, so we permit every build.

What Happens When You Book a Visit

A deck visit starts with a tape measure and a lot of listening. One of us comes out at the time you picked, measures the yard, and asks how you want to use the space. Morning coffee for two people or a graduation party for forty changes the whole design. We sketch options with you at the table and answer questions in plain language.

There is no sales script and nobody waiting in the truck to close you. A few days later you get a written estimate that lays out framing, decking, railings, stairs, and permits, and it costs you nothing. Take your time with it. A deck should still be standing in twenty years, so a week of thinking now is time well spent.
