Composite Deck Builder in Toronto

Toronto's composite deck specialists

Deck Master Inc. has been building decks across Toronto and the GTA for over 20 years, and composite has become the material our clients ask for most. As a Home Depot Pro partner and a Trex-experienced builder, we install premium capped composite and PVC decking that looks like natural wood but never needs sanding, staining or sealing. Every deck is designed, permitted and built by our own crews — not subcontracted out.

If you have been searching for a composite deck builder in Toronto you can trust with a major backyard investment, our 3× HomeStars “Best of” record, 5.0 rating and 2-year workmanship warranty are a good place to start.

Composite & PVC decking brands we install

We are brand-agnostic, so we recommend the board that fits your budget, colour and sun exposure — not whatever is in the warehouse. We regularly install:

Why Toronto homeowners choose composite decking

• Almost zero maintenance — an occasional wash with soap and water is all it needs. No annual staining or sealing.
• 25-year (and longer) warranties — capped composite and PVC resist fading, staining, mould and rot for decades.
• Built for our climate — freeze-thaw cycles, road salt and heavy snow load are hard on wood. Composite shrugs them off.
• A 25–30 year lifespan — two to three times longer than a typical pressure-treated deck in the GTA.
• Cooler, splinter-free boards — modern PVC lines stay cooler underfoot and are safe for bare feet and pets.

Our composite deck building process

1. Free design consultation

We visit your home, measure the space, discuss how you want to use the deck and recommend board lines, colours and railing options — then provide a detailed, itemised quote with no surprises. You will know exactly what you are paying for before any work begins.

2. Permits & engineering

Most decks over 24 inches (600 mm) above grade in Toronto require a building permit. We prepare the drawings and handle the City of Toronto permit process so your deck is fully code-compliant and passes every inspection.

3. Professional installation

Our crews build on properly-footed, code-compliant framing with hidden fasteners for a clean, screw-free surface. Most composite decks are completed in 1–2 weeks depending on size and railing, and we leave your yard clean at the end of every day.

Railings, lighting & finishing touches

A composite deck is only as good as the details around it. We finish our builds with the railings and features that make a deck feel like a true outdoor room:

• Glass railings for uninterrupted views and a modern, open feel.
• Powder-coated aluminum railings — durable, low-maintenance and available in black, white and bronze.
• Integrated deck lighting in posts, stairs and under railings to extend your evenings outdoors.
• Built-in benches, planters and privacy screens to define the space and add function.
• Matching pergolas for shade and architectural presence over dining or lounge areas.

Because we build the framing, decking, railing and features as one integrated project, everything lines up and matches — no mismatched add-ons from three different trades.

Composite deck cost in Toronto

Composite decks in Toronto typically run $45–$75 per square foot installed, depending on the board line, height, railing and site access. A capped-composite board costs more up front than pressure-treated wood, but because you never buy stain and never spend a weekend re-sealing it, composite is usually the cheaper deck over a 15-year horizon.
