How to Install a Trex Composite Deck in Montreal

Complete step-by-step guide for installing trex composite decking in Montreal, Quebec. Includes climate-specific tips for Montreal's continental weather conditions.

Step 1: Check Permits and Plan Your Deck

In Montreal, 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 trex composite quantity needed. Account for frost depth requirements in Montreal (typically 1.2m minimum).

Step 2: Install Footings and Foundation

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

Step 3: Build Deck Frame and Joists

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

Step 4: Install Trex Composite Boards

Install trex composite boards following manufacturer's fastening system. In Montreal'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 Montreal 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 Montreal regulations.

Step 6: Protect Your Deck for Montreal Weather

For Montreal'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.
