What Is Radon?

Essex Homes May Have Radon — And You'd Never Suspect It

Radon is a colourless, odourless, radioactive gas. It’s produced naturally underground as uranium in soil and bedrock breaks down — a process that never stops. The gas travels upward and seeps into homes through cracks in foundations, gaps around service pipes, and any other small opening at or below ground level. Once inside your home, radon has no way to escape. It accumulates, and over months and years of exposure, the health risk compounds significantly. In Essex, Ontario, local geology and soil composition mean radon is a genuine concern for many homeowners. Windsor Radon gives Essex families clarity. Our certified testing removes the guesswork and gives you accurate, actionable results — so you can protect your home with confidence.

Why Every Essex Home Deserves a Radon Test

Health Canada is clear: if your home’s radon level exceeds 200 Bq/m³, corrective action should be taken. But radon is completely invisible without proper testing — and many homeowners go years without knowing their risk.

No Warning Signs

Radon causes no immediate symptoms. By the time health effects appear, years of exposure may have already occurred. Testing is the only early warning system you have.

Lung Cancer Risk

After smoking, radon is the leading cause of lung cancer in Canada. It’s the #1 environmental cause for non-smokers, and the risk is directly linked to the concentration in your home.

Every Home Is Different

Your neighbours’ results don’t predict yours. Radon varies dramatically between properties. Only a certified test of your specific home gives you a reliable, accurate answer.

Frequently Asked Questions

What is Radon gas?

Radon is a colourless, odourless, radioactive gas produced naturally when uranium in soil and rock breaks down. It enters homes through foundation cracks and gaps, accumulates indoors, and poses a serious health risk when levels are elevated over time. It’s one of the leading causes of lung cancer in Canada, responsible for approximately 3,200 deaths annually according to Health Canada.

Is Radon a concern in Essex, Ontario?

Yes. Radon is present throughout Ontario, and Essex is no exception. Local soil and bedrock composition can contribute to elevated concentrations in residential properties. Because radon levels can vary significantly between nearby homes, testing your specific property is the only reliable way to assess your risk.

How is Radon measured, and what's the safe level?

Radon is measured in Becquerels per cubic metre (Bq/m³). Health Canada recommends taking corrective action if your home’s radon concentration exceeds 200 Bq/m³. Windsor Radon provides lab-verified, certified results measured against this guideline so you know exactly where your home stands.

How long does a Radon test take?

Short-term tests take a minimum of 48 hours. They’re fast and suitable for real estate transactions or quick assessments. Long-term tests run for 91 days or more and provide the most accurate, seasonally averaged reading of your home’s radon levels. Windsor Radon will help you choose the right test type based on your timeline and needs.

What happens if my levels are above 200 Bq/m³?

It means action is recommended, and Windsor Radon will walk you through exactly what to do next. We’ll install a sub-slab depressurization system — a proven, minimally invasive solution that draws radon from beneath your foundation and vents it safely outdoors. After installation, follow-up testing confirms the result. The entire process is handled by our certified team from start to finish.

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.
