How to Install a Trex Composite Deck in London

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

Step 1: Check Permits and Plan Your Deck

In London, verify permit requirements with local building department. Check specific height and setback requirements. Measure your space, plan deck layout, and determine trex composite quantity needed. Account for frost depth requirements in London (typically 1.2m minimum).

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

Step 6: Protect Your Deck for London Weather
