What Is Radon?
Radon Can Build Up in LaSalle Homes Without Any Visible Warning
Radon is a naturally occurring radioactive gas formed when uranium in the ground breaks down over time. The gas moves through the soil and can enter homes through foundation cracks, sump pits, utility penetrations, floor drains, and other small openings. Because radon is colourless, odourless, and tasteless, it can accumulate indoors for years without homeowners realizing it.
In LaSalle, radon levels can vary significantly from one home to another. Factors such as local geology, foundation type, building construction, and ventilation all influence how much radon may enter and remain inside a home. Even neighbouring properties can have very different radon concentrations.
The only way to know your home’s radon level is through certified testing. Windsor Radon provides professional radon testing using C-NRPP approved methods and accredited laboratory analysis, giving LaSalle homeowners reliable results they can trust.
16%
Of Canadian homes exceed the Health Canada guideline.
Approximately 1 in every 6 Canadian homes has indoor radon levels above Health Canada’s recommended guideline. Since radon cannot be detected by sight, smell, or taste, many homeowners remain unaware until their property is professionally tested.
Why Radon Testing in LaSalle Is Non-Negotiable
Health Canada recommends taking action when indoor radon concentrations exceed 200 Bq/m³. Professional testing is the only reliable way to determine whether your home exceeds this level and whether mitigation is needed.
Lung Cancer Risk
Radon is the second leading cause of lung cancer in Canada and the leading environmental cause among non-smokers. Long-term exposure to elevated radon levels can significantly increase health risks, making regular testing an important part of maintaining a healthy home.
Every Home Should Be Tested
Whether your LaSalle home is newly built or decades old, features a finished basement, crawl space, or slab foundation, radon can still enter through the building’s foundation. No home is automatically protected based on its age or design.
Health Canada's Action Level
The recommended action level established by Health Canada is 200 Bq/m³. Our certified testing reports clearly identify your home’s radon concentration, helping you understand whether mitigation is recommended.

Following installation, we perform certified follow-up testing to verify that radon levels have been successfully reduced and that the mitigation system is operating effectively.
