Winterizing Your Montreal Home: Inspector's Checklist

Key Takeaways:

• Montreal winters demand serious home preparation
• Ice dams can cause significant damage
• Professional heating inspection prevents emergencies

Why Winterizing Matters in Montreal

Montreal winters are no joke. With temperatures dropping to -30°C and over 200cm of annual snowfall, inadequate winterization can lead to catastrophic damage and expensive repairs.

What is Winterizing a Home?

Winterizing means preparing your home's systems and structure to withstand extreme cold, snow loads, and freeze-thaw cycles. It's preventive maintenance that protects your largest investment.
