Key Point 1: What Is a Freeze & Thaw Cycle

A freeze & thaw cycle occurs when water penetrates stucco, freezes overnight, and thaws during the day. Each cycle causes expansion and contraction, which slowly weakens the surface. Over time, these cycles lead to cracks, delamination, and structural damage. Fact: Calgary can experience over 100 freeze & thaw cycles each winter, putting exterior finishes under constant stress. 

Key Point 2: How Freeze & Thaw Cycles Damage Stucco

  • Cracking and Flaking: Repeated freezing expands water trapped inside, widening small cracks. 
  • Water Infiltration: Meltwater seeps deeper into the wall layers, increasing moisture retention. 
  • Delamination: The stucco surface separates from the base, leading to chunks breaking off. 
  • Staining and Mold Growth: Persistent moisture leads to dark stains and mildew formation. 

Eco-Max Insight: These issues not only affect your home’s appearance but also compromise its insulation and energy efficiency. 


Key Point 3: How to Prevent Freeze & Thaw Damage 

  • Regular Inspections: Inspect your stucco every fall to identify cracks or weak points before winter hits. 
  • Seal Cracks Early: Small cracks can be sealed with breathable, eco-friendly coatings that protect against moisture but allow vapour to escape.
  • Improve Drainage: Ensure gutters and downspouts are clean and direct water away from stucco surfaces. 
  • Hire Professionals: DIY fixes may hide problems temporarily but often worsen them. Eco-Max Construction uses advanced moisture detection tools and eco-conscious repair methods to ensure lasting protection. 

Key Point 4: Benefits of Preventive Stucco Maintenance 

  • Extends the life of your stucco exterior 
  • Reduces repair costs 
  • Improves home energy efficiency 
  • Maintains curb appeal year-round
