Wood & Composite Deck Building in Montreal
A solid, welcoming deck designed to become the heart of your outdoor living, from spring through fall.
A well-built deck is another room added to your home. At L'Île Verte, we design and build wood and composite decks for residential and commercial properties across Montreal, Laval and the entire North Shore. Whether you picture a ground-level deck for entertaining, a raised deck off your second-floor patio door, or a multi-level outdoor living space, we build a structure that's solid, square and made to ride out our winters.
We guide you from material choice to the final screw: treated wood, cedar, or maintenance-free composite — we give you an honest breakdown of each based on your budget, your use and the look you're after. Because we're a four-season company, the same crew that builds your deck knows your property all year round — a real advantage for footings, drainage and durability. Request your free quote today.
A deck built for Quebec's freeze-thaw cycles
A deck that lasts starts below the boards, in the foundation. Our freeze-thaw winters heave and twist poorly anchored structures, which is why we set footings that reach below the frost line, whether with helical screw piles or poured footings. Solid anchoring, joists at the right spacing and drainage planned from the start are what separate a deck that stays square after ten years from one that warps by its second spring. In Montreal, Laval or on the North Shore, that groundwork makes all the difference.
The right material depends on how you live. Treated wood offers the best value and can be stained to your taste, but it needs regular upkeep. Cedar is naturally more rot-resistant, smells great and ages beautifully when it's protected. Composite costs more up front but asks for almost no maintenance: no staining, no sanding, no splinters, and colour that holds for years. We walk you through the options with no pressure and help you pick what truly suits your use and budget.
A deck is often the start of a real outdoor living space. We can fold it into a complete layout: a raised deck with stairs down to an interlock paver section, matching railings, a built-in bench, or privacy from a lattice or fence section. Whether it's a residential backyard or a commercial project in Greater Montreal, we plan it all so the deck ties in with your home, your yard and the rest of your landscaping. It all starts with a site visit and a free quote.
Frequently asked questions
- Treated wood, cedar or composite — which should I choose for my deck?
- It comes down to your budget and how much maintenance you're willing to do. Treated wood is the most affordable and can be stained to your taste, but needs upkeep every two to three years. Cedar is naturally rot-resistant and good-looking, with moderate maintenance. Composite costs more to buy but asks for almost no upkeep and holds its appearance for years. We assess how you'll use the deck and give you an honest recommendation.
- What affects the cost of a deck?
- Several factors come into play: the size, the material chosen (treated wood, cedar or composite), the number of levels, the height and therefore the type of foundation, whether there are stairs and railings, and how accessible the site is. A raised deck takes more structure than a ground-level one. We assess your project on site and provide a free, detailed quote with no surprises.
- Do I need a permit to build a deck in Montreal or Laval?
- Often, yes — especially for a raised deck, one attached to the house, or one over a certain size. Rules vary from one municipality to the next across Greater Montreal, and some boroughs have their own requirements. We'll tell you what applies to your project and can help prepare the plans your city needs for the permit application.
- How long does a deck last, and what maintenance does it need?
- With a foundation set below the frost line and solid framing, a deck easily lasts many years. Treated wood and cedar need cleaning and a coat of stain or sealant every two to three years to age well. Composite only needs the occasional cleaning. We hand you clear care guidance based on the material you choose when the job is done.
