How to Install a Composite Decking Deck in Toronto

Complete step-by-step guide for installing composite decking decking in Toronto, Ontario. Includes climate-specific tips for Toronto's great lakes weather conditions.

Step 1: Check Permits and Plan Your Deck

In Toronto, verify permit requirements with local building department. Major cities typically require permits for decks over 2 feet high. Measure your space, plan deck layout, and determine composite decking quantity needed. Account for frost depth requirements in Toronto (typically 1.2m minimum).

Step 2: Install Footings and Foundation

Dig footings to required depth for Toronto (1.2m or deeper to prevent frost heave). Standard concrete footings work well. Ensure footings are level and properly spaced for composite decking installation requirements.

Step 3: Build Deck Frame and Joists

Install ledger board (if attaching to house), beams, and joists according to Composite Decking manufacturer specifications. Follow joist spacing requirements for composite materials (typically 12-16 inches on center).

Step 4: Install Composite Decking Boards

Install composite decking boards following manufacturer's fastening system. In Toronto's climate with temperature swings, leave proper expansion gaps (typically 6-8mm) between boards. Hidden fastener systems provide clean appearance. Work in moderate temperatures (10-30°C) for best results.

Step 5: Install Railings and Finishing Touches

If deck is elevated, install railings meeting Toronto building code (typically 36-42 inches high). Use matching composite or aluminum railing systems. Add stairs if needed, ensuring proper rise and run dimensions. Complete final inspections as required by Toronto regulations.

Step 6: Protect Your Deck for Toronto Weather

For Toronto's harsh winters: seal all gaps before winter, ensure proper drainage to prevent ice buildup, and remove snow carefully to avoid surface damage. Clear snow with plastic shovel, not metal.
