Custom composite decks,engineered to last.
Wood-free, low-maintenance decking built to one uncompromising standard — the parts you can't see made as carefully as the parts you can. We don't sell decks. We guide decisions.
You'll love the deck. You'll remember the experience.

A composite deck is a decision, not a purchase.
The deck is the product. The experience is our reputation.
Most companies sell you a deck. We help you make a decision you won't second-guess — about materials, structure, and the people you let into your backyard for six weeks — then build it to a standard that outlasts the trend that sold it.
Doing things correctly often costs more. We're comfortable with that.
What makes a LeBlanc composite deck different
A beautiful surface is easy to sell. A deck that's still true in year fifteen is built underneath, where no one looks. Every LeBlanc deck is built to the same five-part standard — the LeBlanc Build Standard.
Mechanical footings
Helical footings that bear load immediately — no concrete to cure, and posts stay up out of ground moisture.
KDAT framing
Pressure-treated through the whole board and dimensionally stable, so the frame stays straight instead of twisting and cupping.
Wood-free surface
Composite decking and railings that won't rot, splinter, or need refinishing every summer.
Hidden fasteners
A clean surface with no screw heads. The kind of detail you feel underfoot.
Full trim-out
Trimmed fascia and enclosed stair risers — clean, finished edges instead of raw board ends.
Built as one system — not five separate upgrades.
Mechanical footings, KDAT framing, and a mineral-based composite surface like Deckorators Voyage aren't options you add on. Together they're the LeBlanc Deck System — engineered as one structure, from the ground up. It's the reason we can stand behind the whole deck, not just the boards on top.
Backed by our 3-Year Workmanship Warranty — and it transfers once to the next owner. See what's covered →
The last deck surface you'll choose.
Wood asks for a decision every year: sand it, stain it, seal it, or watch it grey and splinter. Modern composite doesn't. It gives you the warmth of real timber without the maintenance calendar.
Premium composite, in your color.
Every LeBlanc deck is wood-free — no rot, no splinters, no refinishing. We build on Deckorators as our core line: Voyage is the flagship, Summit the value tier beneath it. When a project calls for a particular look or a specialized application, we reach for the other lines we trust.
Deckorators Voyage
Our flagship and standard surface — a mineral-based composite built on Deckorators Surestone® Technology. The strongest board we build with, in rich, multi-tonal streaked colors, engineered for traction underfoot, lower heat on sunny days, and minimal seasonal movement. It's the surface at the heart of the LeBlanc Deck System.
Fullest warranty of any line we carry: 50-yr structural · 25-yr stain & fade · 25-yr removal & replacement.
Seven colorways: Sedona · Mesa · Sierra · Tundra · Khaya · Costa · Dark Slate
Need to stretch the budget? The value tier beneath Voyage.
Deckorators Summit
Also built on Surestone® mineral-based composite, but lighter (about 30% less material) with a matte, low-gloss finish — the budget-friendly step down from Voyage, not the flagship. Warranty covers 50-yr structural and 25-yr stain & fade (no removal & replacement).
Earth-tone colorways: Glacier · Boulder · Cliffside
Other lines we build with.
Each of these is a step in a specific direction — a particular look, a tighter budget, or a waterproof, ground-contact, or waterfront application.
Deckorators Venture
Entry-level Deckorators composite — the value-minded option. Colorways: Sandbar · Saltwater.
Eva-Last Eclipse
Rich, variegated color with a natural read. Colorways: Dockside Brown · Shoreline Gray · Autumn Mahogany.
TimberTech AZEK
Advanced PVC in two collections — Vintage and Legacy — with hardwood-inspired tones (12 colorways).
Nexan LockDry
Aluminum, fully water-tight decking that keeps the space below dry. Colorways: Light Grey · Granite Grey · Saddle Brown · Buckskin.
Owens Corning Marine-Grade (WearDeck)
Fiberglass-reinforced and fully submersible — built for wet, ground-contact, and waterfront settings.
Fiberon
Composite and PVC decking, carried on request. Collections: Sanctuary, Horizon, and the 2026 Novus line.
Seven tones, from red-rock to slate.
Colorway names are exact (Deckorators Voyage); the on-screen colors are approximate — swap in true manufacturer photos in Elementor. Standard framing is KDAT — pressure-treated through the whole board, dimensionally stable, and pre-stained — with steel, Owens Corning® Structural Lumber (fiberglass-reinforced), or aluminum framing available as upgrades. Foundations use mechanical (helical) footings wherever the site allows. We'll bring real samples to your consultation so you choose in your own light.
Multi-width boards
Mixed board widths for a custom, high-end floor that never looks off-the-shelf.
Herringbone & inlays
Statement patterns that turn the surface itself into the feature.
Picture-frame borders
A clean border that frames the deck and hides every board end.
Trim & skirting
Horizontal, vertical, or lattice skirting — the finish that completes the structure.
You'll always know exactly where things stand.
The stories people carry about contractors are rarely about the wood. They're about being left in the dark.
So we built the opposite. From the first consultation to the final walkthrough, you see everything — a customer portal with your schedule, your selections, and daily logs and photos as the work happens.
No surprises. No chasing us for updates. One team, start to finish.

The work speaks. So do the people we build for.
"Highly recommend LeBlanc Decks. Great communication throughout and even better craftsmanship. My deck project had some tricky elements to it and LeBlanc came in with a problem solving mindset. Transformed my old rotted wooden deck into a strong composite deck which I can actually enjoy."
"I just cannot say enough good things about our LeBlanc Decks experience… The construction team must be the most on point contractors that I have ever had the pleasure of having work on my home. They were punctual, communicative, and friendly… Their knowledge and skills gave us an end result that far exceeds all expectations. These are the people you want on your project!"
"I just want to comment on the kindness of the gentlemen in this company… four of their men saw to it that the refrigerator was safely up our very, very steep driveway and out of the pickup. This is the kind of company we will do business with, the kind that care. Thank you LeBlanc Decks!"
Everything that makes a deck complete.
A LeBlanc deck is more than a floor. These are the details we design in from the start — each one built to the same standard.
Railings
Powder-coated aluminum with picket, cable, or glass infill — it won't rot or warp, and the cable option holds the view instead of blocking it.
Explore railings →Lighting
Low-voltage LED — riser, flush, and railing lighting that makes the deck usable, and beautiful, after dark.
Explore lighting →Under-Deck Systems
Underdeck ceilings and EPDM water diversion that turn the space below into dry, usable room.
Explore under-deck →Waterproofing & Drainage
Keep water where it belongs — protecting the structure and the space underneath for years.
