What Is Radon?
Leamington Homes Could Have Elevated Radon Levels Without You Knowing
Radon is a naturally occurring radioactive gas created when uranium found in soil and rock slowly breaks down. As the gas rises through the ground, it can enter homes through foundation cracks, sump pits, construction joints, floor drains, and utility openings. Because radon is invisible, odourless, and tasteless, it can build up indoors without any obvious warning signs.
In Leamington, radon levels can vary from one property to another due to differences in local geology, foundation construction, ventilation, and building design. Two neighbouring homes may have completely different radon readings, making assumptions about your home’s safety unreliable.
The only dependable way to determine your home’s radon level is through certified testing. Windsor Radon uses C-NRPP approved testing methods and accredited laboratory analysis to provide Leamington homeowners with accurate, trustworthy results.
16%
Of Canadian homes exceed the Health Canada guideline.
Approximately 1 in every 6 Canadian homes has radon levels above Health Canada’s recommended guideline. Since radon cannot be detected without testing, many homeowners are unaware their families may be exposed. Professional testing is the only way to know your home’s actual radon level.
Why Radon Testing in Leamington Is Non-Negotiable
Health Canada recommends taking action when indoor radon concentrations exceed 200 Bq/m³. Because radon cannot be seen, smelled, or tasted, certified testing is the only reliable way to determine whether your home exceeds this recommended threshold.
Lung Cancer Risk
Radon is the second leading cause of lung cancer in Canada and the leading environmental cause among people who have never smoked. Long-term exposure to elevated radon concentrations increases health risks, making routine testing an important part of protecting your family’s well-being.
No Home Is Automatically Safe
Whether your Leamington home is newly built, decades old, has a basement, crawl space, or slab foundation, radon can still enter through the building’s foundation. Every home should be professionally tested regardless of age or construction style.
The 200 Bq/m³ Action Level
Health Canada’s recommended action level is 200 Bq/m³. Our certified testing reports clearly explain your home’s radon concentration and whether mitigation is recommended, allowing you to make informed decisions with confidence.

Elevated Levels? We Handle the Whole Process.
Finding elevated radon levels doesn’t have to be stressful. Windsor Radon manages the entire mitigation process—from your initial assessment through final verification—making it easy to improve your home’s indoor air quality with minimal disruption.
1
Site Assessment
We begin by reviewing your certified test results, inspecting your home’s construction and foundation, and identifying the most effective mitigation solution for your specific Leamington property.
2
System Installation
Our primary mitigation method is sub-slab depressurization, the industry-standard solution for reducing indoor radon levels. The system safely captures radon beneath your foundation and vents it outdoors before it enters your living space. Most installations are completed in one day.

Post-Installation Testing
Once your mitigation system has been installed, we perform certified follow-up testing to verify that radon concentrations have been successfully reduced and that your system is operating as intended.

Your mitigation system works quietly around the clock with minimal maintenance, continuously reducing radon levels and helping maintain healthier indoor air for years to come.

Frequently Asked Questions
What is Radon gas?
Radon is a naturally occurring radioactive gas produced when uranium in soil and rock breaks down. It enters homes through foundation openings and can accumulate indoors without any visible signs. Because Radon has no colour, smell, or taste, professional testing is the only reliable method of detection.
Is Radon a concern in Leamington?
Yes. Elevated radon levels have been found in homes throughout Ontario, including Leamington and surrounding Essex County communities. Since every home is different, professional testing is the only way to determine your property’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 longer and offers the most reliable assessment of your home’s average annual radon exposure.
What if my home's Radon level exceeds 200 Bq/m³?
If your certified test results exceed Health Canada’s recommended guideline, Windsor Radon will design and install a customized mitigation system that effectively reduces indoor radon concentrations. We verify every installation through post-mitigation testing.
Do I need to leave my home during testing or mitigation?
No. Radon testing is completely non-invasive, and most mitigation systems can be installed while homeowners remain in the home with minimal interruption to their daily 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.
