Understanding Radon Gas and Tarion’s Warranty Coverage

Radon Gas: A Growing Concern for Homeowners In recent years, awareness of radon gas exposure has increased, especially among new home buyers. Health Canada released a report in 2012 stating that long-term exposure to radon gas could be responsible for up to 16% of lung cancer cases. As a result, more attention is being given to radon-related risks and mitigation measures in residential properties. Tarion’s Warranty Coverage for Radon Gas Tarion has established guidelines for addressing radon gas claims under its home warranty coverage. If radon levels exceed Health Canada’s recommended limit of 200 Bq/m³, the issue is eligible for coverage under Tarion’s warranty program. To ensure consistency in warranty decisions, Tarion employees follow a specific set of guidelines when evaluating radon-related claims.

Radon 101: What Every Homeowner Needs to Know

What is Radon? Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil, rock, and water. It seeps into homes through cracks in foundations, gaps around pipes, and other openings. Because it is colorless, odorless, and tasteless, radon can accumulate in indoor spaces without detection, posing significant health risks. The Health Risks of Radon Exposure Radon and Lung Cancer Exposure to elevated radon levels is a leading cause of lung cancer among non-smokers. According to Health Canada, radon exposure is responsible for approximately 16% of lung cancer deaths each year. Smokers who are also exposed to radon have an even higher risk of developing lung cancer. How Common is Radon in Canadian Homes? Health Canada’s National Radon Survey found that up to 44% of homes in certain regions exceed the recommended radon guidelines. While most testing has been conducted in residential properties, radon is also present in workplaces, schools, and commercial buildings. Radon and Building Codes in Canada National Building Code Requirements The National Building Code of Canada includes specific measures to facilitate radon mitigation in new constructions. These provisions make it easier to install a full mitigation system if post-occupancy radon testing reveals high levels. Key Building Code Requirements: Important Considerations for Homeowners While these building measures are valuable, they do not fix radon on their own. If radon levels are high, a mitigation system must be activated by a C-NRPP-certified Radon Professional.
