Frequently Asked Questions
Why should I test for radon?
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.No. Radon can affect any home—whether it was built yesterday or 100 years ago.

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 depressurization to vent radon safely outside. After installation, we verify that levels have been reduced to safe levels.
