Radon services in Calgary, Alberta address an invisible yet serious health risk in many homes. Radon is a radioactive gas produced by natural decay of radium in soil and rock across Alberta. It is colourless, odourless, and tasteless, and cannot be detected without specialised testing. Pressure differences between soil and buildings allow it to enter basements through cracks, joints, and floor drains, where homes act like a vacuum. Classified as a Grade 1 human carcinogen, it is associated with lung cancer, especially in non-smokers. In Calgary, roughly one in six homes, and up to one in three in some cases, exceed Health Canada limits, making exposure a significant concern.
We provide professional radon testing and mitigation to accurately measure and reduce indoor levels. Health Canada recommends long-term testing over 91 days to capture seasonal variation, and we also offer short-term 96-hour testing for real estate using C-NRPP certified technicians and calibrated equipment. When elevated levels are found, we install sub-slab depressurization systems that create a controlled vacuum beneath the foundation, redirecting radon outdoors and reducing levels by up to 95 percent. Our quality assurance includes sealing entry points, documenting work stages, and conducting duplicate, blind, and spike testing, with results verified through continuous monitoring. Radonators, an Alberta-owned company led by Sam Mathews, provides certified service, transparent practices, and a 10-year warranty across Calgary and surrounding areas.

Our radon testing service is designed to assess indoor air safety in homes. This naturally occurring, odourless gas is recognised in Canada as a major cause of lung cancer. It may seep into buildings through cracks in foundations and gaps in construction materials. Testing can be conducted over short or long durations depending on requirements. 
Elevated radon levels are a common concern in Calgary residences, and we provide professional mitigation services to address them. We advise that sealing cracks or ventilating basements alone is insufficient to control radon effectively. Our system uses sub-slab depressurization to capture soil gas at the source and significantly reduce radon levels. We carry out diagnostics, installation, and continuous monitoring to ensure reliable long-term performance and compliance.
