Composite Deck Builders in Toronto & GTA

From basic ground-level builds to multi-level decks with glass railings, Kerta builds every residential deck configuration in Toronto. Your material selection shapes cost, appearance, and upkeep, so we walk through the options with you at the consultation.

Pressure-Treated Wood Decks

Pressure-treated wood remains one of the most common choices for homeowners who want a natural wood look.

The trade-off is frequent maintenance: in Toronto's climate, staining and sealing every two to three years protects the wood against moisture, UV exposure, and freeze-thaw cycles.

Pressure-treated decking is often a practical choice for homeowners who want a straightforward outdoor space, or who are planning to sell within the next decade.

Composite Decks

As a composite deck builder in Toronto, we install premium composite decking from:

• Trex Enhance, Select, and Transcend
• TimberTech Edge and Pro

Composite decking needs no staining or sealing, and its upkeep is light: most homeowners wash the surface twice a year with soap and water. It gives you the look of wood without the weekends of maintenance, in a wide range of colours and finishes.

Families with children and pets appreciate the splinter-free surface. Many composite systems last 25 to 50 years, depending on the product line. Newer collections such as Trex Pebble Beach, Trex Golden Hour, and TimberTech Harvest+ keep widening the colour and design ideas available to homeowners.

Cedar Decks

Cedar is one of the most requested materials across Toronto. It naturally resists insects and decay, and it brings the warmth and character of a real wood deck.

Like pressure-treated lumber, cedar needs periodic staining and upkeep. With proper care, a cedar deck lasts for decades and develops a rich, aesthetically pleasing look that suits mature Toronto streets.

Multi-Level and Elevated Decks

Many Toronto properties have elevation changes that suit multi-level decks. Multi-tiered layouts give you separate zones for dining, entertaining, lounging, and garden access, and they make good use of sloped or uneven yards.

Elevated structures often need engineering review and permit approval. We manage those requirements for you, so the project starts correctly and stays within local building codes.

Glass and Premium Railing Systems

Railings affect both the look and the budget of a deck. Glass railings give a modern finish and keep views open, which is why they are popular across Toronto, where homeowners want to see the landscaped yard.

• Wood railings
• Aluminium railings
• Glass railings
• Cable and composite railing systems

We also build stairs, back-door landings, and other types of deck structures that connect the house to the yard. To see finished examples, browse our deck and outdoor living portfolio.

Built Right From the Footings Up

A deck is only as good as what holds it up. Footings have to reach below the frost line so Toronto's freeze-thaw cycle does not heave the structure. Set posts are plumbed and tied into beams and a correctly spaced frame. We use the right fasteners and hardware for each material, including corrosion-resistant screws and structural connectors for the frame and the fastening system each composite maker specifies, because the wrong fasteners can shorten a deck's life and affect manufacturer warranties.
