Radon & Your Crawl Space: Why Encapsulation Matters
When we think of crawl space encapsulation, moisture, mold, and cold floors often come to mind. But there’s another invisible danger that many homeowners overlook: radon gas.
What is Radon?
Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in the soil. It's colorless, odorless, and tasteless; making it impossible to detect without specialized tests. In high concentrations, radon is a serious health risk and is the second leading cause of lung cancer in Canada, after smoking.
Why Your Crawl Space Matters
Your crawl space acts like a gateway between the ground and your home. If it's unsealed, radon gas can easily seep through cracks, gaps, or exposed soil, entering your living space.
Since up to 50% of the air on the first floor of your home comes from the crawl space, whatever’s under your home ends up in your lungs too.
How Encapsulation Helps
Crawl space encapsulation involves sealing the floor and walls with a durable vapor barrier, often paired with a dehumidifier & an air purifier. This creates a protective barrier that:
- Stops radon gas from entering your home
- Reduces moisture and mold risk
- Improves indoor air quality
- Increases energy efficiency
For homes in regions with high radon levels (like many parts of Quebec) encapsulation is not just a comfort solution; it's a health priority.
