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.

Elevated Levels? We Handle the Whole Process

1
Site Assessment
We begin by reviewing your radon test results, inspecting your home’s foundation, and evaluating the overall structure to determine the most effective mitigation strategy for your LaSalle property.

Our preferred solution is sub-slab depressurization, the most effective radon mitigation method available. The system safely removes radon from beneath your home’s foundation and vents it outdoors before it enters your living space. Most installations are completed within one day.

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.

Frequently Asked Questions
What is Radon gas?
Radon is a naturally occurring radioactive gas produced when uranium breaks down in soil and rock. It enters homes through small openings in the foundation and can accumulate indoors without any visible warning signs. Professional testing is the only reliable way to detect it.
Is Radon common in LaSalle?
Yes. Elevated Radon levels have been identified in homes throughout Ontario, including LaSalle and surrounding Essex County communities. Because every property is different, professional testing is the only way to determine your home’s Radon level.
How long does a Radon test take?
Short-term testing requires at least 48 hours and provides accurate results quickly. Long-term testing lasts 91 days or more and offers the most reliable measurement of your home’s average annual radon concentration.
What if my Radon level is above 200 Bq/m³?
If your certified test results exceed Health Canada’s recommended action level, Windsor Radon will design and install a customized mitigation system to reduce indoor radon levels. We also verify the system’s effectiveness through follow-up testing.
Do I need to leave my home during testing or mitigation?
No. Radon testing is non-invasive, and most mitigation systems can be installed while homeowners remain in the house with very little disruption to their normal routine.
Frequently Asked Questions
Why should I test for Radon?
Radon is the leading cause of lung cancer in non-smokers and is responsible for thousands of deaths each year in Canada. It’s an invisible, odorless gas that can only be detected through testing. Essex County has higher than average Radon levels, making testing especially important for homeowners in our area. Testing is the only way to know if your family is at risk.
What are safe Radon levels?
Health Canada’s guideline is 200 Bq/m³. If your home tests above 200 Bq/m³, Health Canada recommends taking action to reduce levels. However, there is no “safe” level of Radon—any exposure carries some risk. The lower the level, the better. Our goal with mitigation is to reduce levels as far below 200 Bq/m³ as possible.
What does C-NRPP certified mean?
C-NRPP stands for Canadian National Radon Proficiency Program. It means we’ve completed rigorous training, passed certification exams, and follow strict standards set by Health Canada. Choosing a C-NRPP certified professional ensures your Radon system is installed correctly and will actually reduce Radon levels. Our certification is your assurance of quality work.
Does Radon affect pets and children?
Yes. Pets and young children are especially vulnerable to Radon exposure because they spend more time closer to the ground where Radon concentrations are often highest. Children’s growing bodies and faster breathing rates also make them more susceptible to Radon’s harmful effects. If you have pets or young children in your home, Radon testing becomes even more important for their health and safety.
Should I test when buying or selling a home?
Yes, we recommend Radon testing for both buyers and sellers. While not always required in Ontario, many home buyers request Radon testing as part of their due diligence. If you’re selling, having a recent Radon test shows transparency and can prevent delays during negotiations. If you’re buying, testing helps you understand what you’re getting into. Having mitigation done by a C-NRPP certified professional like us ensures the work is done properly and can be verified.
Does the age of my house matter?
No. Radon can affect any home—whether it was built yesterday or 100 years ago. New homes can have Radon just as easily as older homes. Construction methods, soil composition, and foundation type matter more than age. The only way to know if your home has elevated Radon levels is to test. Don’t assume your new home is safe, and don’t assume your old home has a problem. Test to know for sure.
How long does testing take?
Long-term Radon testing takes a minimum of 90 days to get accurate results. This follows Health Canada’s guidelines for proper testing. We place the test device in your home, and it measures Radon levels continuously over the 90-day period. After that, we analyze the results and provide you with a clear report. New homes can have Radon just as easily as older homes. Construction methods, soil composition, and foundation type matter more than age. The only way to know if your home has elevated Radon levels is to test. Don’t assume your new home is safe, and don’t assume your old home has a problem. Test to know for sure.
Is mitigation disruptive to my home?
Radon mitigation is minimally disruptive. The system typically involves installing a vent pipe and fan. Most of the work is done in the basement or crawl space. You can stay in your home during installation, and the work is usually completed within a day or two. The system operates quietly and requires minimal maintenance.
What happens if Radon levels are high?
If your test shows elevated Radon levels, we’ll discuss mitigation options with you. We design and install professional Radon mitigation systems that reduce Radon levels in your home. Most systems use sub-slab or sub membrane to vent Radon safely outside. After installation, we verify that levels have been reduced to safe levels.
