How the Transition from Summer to Winter Affects Your Home's Foundation, Basement, and Crawl Space
In Québec, the shift from hot, humid summers to freezing, snowy winters puts unique stress on your
foundation, basement, and crawl space. Without proper protection, seasonal changes can lead to moisture problems, structural damage, and higher heating costs.
Here is how this transition impacts your home and what to look out for before winter sets in.
Why Seasonal Changes Matter
- Soil Movement: Summer heat dries out the soil, causing it to shrink. When winter moisture returns, the soil expands and puts pressure on foundation walls, which can lead to cracks.
- Moisture and Humidity: Summer humidity often leaves excess moisture in basements and crawl spaces. In cold weather, condensation worsens, creating mold and air quality problems.
- Freezing Risks: Water in cracks or poorly sealed areas can freeze, expand, and worsen damage. Open crawl space vents also let freezing air in, which can cause frozen pipes and cold floors.
What to Check Before Winter
- Foundation Cracks – Look for gaps or widening cracks inside and outside your foundation.
- Basement Leaks – Check for water stains, efflorescence, or damp areas.
- Crawl Space Conditions – Inspect for musty odors, mold, or dampness. Sealing and encapsulating prevents winter air problems.
- Sump Pump and Discharge Lines – Test your sump pump and ensure discharge lines are protected from freezing with systems like IceGuard®.
- Dehumidification – Make sure your dehumidifier is working to keep humidity under control.
- Insulation – Cold floors and chilly walls often mean poor insulation in basements or crawl spaces.
