Why Develop a Radon Reduction Plan
Posted in Radon Testing, on October 09, 2025
If you’ve recently had radon testing and discovered that your home has unsafe levels of radon gas, what are the next steps? At SafeAir, we specialize in air quality testing in Toronto and can help with advice and in creating a radon reduction plan. Radon gas, while scary, has many safe and effective mitigation strategies that reduce your risk.
Understanding the Risks of Radon Exposure

Radon is a colourless, odourless radioactive gas. It’s formed deep in the earth’s surface, and often collects in our homes after it seeps in through cracks and gaps in the foundation or lower levels. Exposure to high levels of radon gas is linked to the development of lung cancer, and Health Canada advises homeowners with results over 200 Becquerels per cubic metre (200 Bq/m3) to reduce their exposure. Unfortunately, there are no signs or symptoms of radon exposure, and many people don’t know they’ve been exposed until it is too late.
The Importance of a Radon Reduction Plan
When a home tests above the safe level of 200 Bq/m3, the SafeAir team can help you set up a radon reduction plan. Different from a one-time radon mitigation, a reduction plan puts into place regular monitoring, maintenance, and prevention strategies that respond to the changing needs of your household. Radon levels fluctuate seasonally, which can result in the need for different methods for the fall versus the spring. An ongoing plan also helps you understand what remediation strategies are effective, providing peace of mind and manageable, attainable goals.
Key Elements of an Effective Radon Reduction Plan
There are four key elements to an effective radon reduction plan:
- Radon testing is used to determine what levels are present and when or if they change.
- Mitigation systems, like sub-slab depressurization or other techniques, help vent and remove radon gas.
- Sealing and maintenance activities that assess your home’s foundation, sump pumps, windows, or other sub-grade openings to prevent entry.
- Follow-up testing is essential to gauge how far you’ve come and if solutions are working.
Professional Help Vs. DIY Efforts
Radon gas can be tricky to detect accurately, and while we value the can-do attitude of DIYers, professional testing holds several advantages over DIY tests. The most critical is the placement of the testing device. Because radon is sensitive to environmental fluctuations, the installation of the testing device has a significant effect on the accuracy of the results. We’ve seen many DIY tests placed in areas too breezy or too isolated to give trustworthy results — and with something as serious as radon exposure, you want an accurate test!
Additionally, many DIY kits are short-term tests, and these can also have significant inaccuracies. At SafeAir, we always suggest using longer-term testing to reduce false positives and even out those seasonal fluctuations.
Peace of Mind Through Prevention
One of the most important things we do as a company is provide our clients with peace of mind. Air quality testing in Toronto can reduce fears about allergens, anxiety about mold growth, and help you understand the various air quality issues that may affect the health and safety of your home. Radon reduction plans help provide this peace of mind, as well as empowering you with knowledge and a roadmap to safety.
