Deck Builder Toronto
Composite or cedar, ground-level or multi-tier. CNB builds decks engineered to survive a Toronto winter and look better in ten years. Structural assessment, permit, and build — one crew.
Everything in-house. One crew, start to finish.
Composite Decking
Trex, TimberTech or Fiberon. 25-year fade/stain warranty, zero splinters, no annual sealing. Best long-term value for Toronto's freeze-thaw climate.
Cedar & Pressure-Treated
Classic look, lower upfront cost. Kiln-dried lumber, proper joist spacing, stainless fasteners. Requires annual sealing — we advise on maintenance schedule.
Underdeck Rain-Escape
Drainage channel between deck joists creates a dry patio underneath. Usable storage or outdoor living space year-round, regardless of weather above.
Multi-Level & Pergola
Floating decks, elevated platforms, integrated stairs, planters, pergola roofing. Custom-engineered when required. LED lighting conduit rough-in included.

No Surprises
Every scope in writing. Every inspection scheduled. Every certificate handed to you at the end. We call you before we open walls — never after.

What homeowners ask before hiring us
In Toronto, decks over 24 inches above grade OR attached to the house require a Building Permit. We handle the application and track it through the City.
Composite wins on 20-year total cost (no staining, no rot, no annual maintenance). Cedar wins on upfront price and traditional look. We show you both on site.
Timelines depend on size and complexity — a ground-level deck moves quickly, a multi-level with pergola takes longer. We give a firm written schedule before you sign.
Quality outdoor living adds real resale appeal in Toronto. Well-built composite decks consistently accelerate sale timelines in a competitive market.
We include electrical conduit rough-in as standard on every deck. Full lighting installation (transformer, wire runs, fixtures) coordinated with our licensed electrician.
