Radon is a naturally occurring radioactive gas found in the soil beneath our dwellings.
In Quebec—where long winters keep us indoors and basements are commonly used as living areas—testing for radon is essential for protecting your family’s long-term health.

1. A Leading Cause of Lung Cancer
Radon is the #1 cause of lung cancer among non-smokers, and the risk increases significantly with long-term indoor exposure.
2. Impossible to Detect Without Testing
Radon has no smell, colour, or taste. A certified radon test is the only reliable way to know if your home is affected.
3. Higher-Risk Zones Near Montreal
Neighbourhoods such as the West Island, South Shore, Laval, and the Laurentians have soil conditions that increase radon potential.
4. Older Foundations Are Vulnerable
Many Montreal homes with stone or concrete-block foundations allow radon to seep through cracks and structural joints.

5. Basements Used as Living Space
Basements used as bedrooms, offices, playrooms, or home gyms result in greater exposure to radon—where levels naturally tend to be higher.
If this applies to your home, you can book a certified radon test in minutes.
6. Long Heating Seasons Trap Radon Indoors
Closed windows during long winter periods in Quebec reduce ventilation and allow radon to accumulate.
7. All Housing Types Can Be Affected
Condos, duplexes, triplexes, townhomes, and single-family dwellings can all show elevated radon test results.
8. Testing Is Simple and Affordable
Radon testing is simple and affordable when performed by certified professionals.
