What's included

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.
