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 pressure-treated wood quantity needed. Account for frost depth requirements in Montreal (typically 1.2m minimum).

Install pressure-treated wood boards with proper spacing (3-5mm) for expansion. Seal with quality deck sealer within 2 weeks of installation. Pre-drill screw holes to prevent splitting.

Step 5: Install Railings and Finishing Touches

If deck is elevated, install railings meeting Montreal building code (typically 36-42 inches high). Wood railings should match deck material and finish. 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. Apply winter-grade sealer in fall.
