Step 1: Check Permits and Plan Your Deck

In Winnipeg, 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 Winnipeg (typically 1.2m minimum).

Step 2: Install Footings and Foundation

Dig footings to required depth for Winnipeg (1.2m or deeper to prevent frost heave). Use frost-protected footings with drainage. 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 Winnipeg'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 Winnipeg 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 Winnipeg regulations.

Step 6: Protect Your Deck for Winnipeg Weather

For Winnipeg'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.
