At Radonators, we view radon as a significant yet often overlooked hazard in Calgary homes. It is a radioactive gas formed through the natural decay of radium in Albertas soil and rock. Because it is colourless, odourless, and tasteless, it cannot be detected without specialised testing. Differences in air pressure between buildings and the ground allow radon to enter basements through cracks and service penetrations. Classified as a Grade 1 human carcinogen, it is associated with lung cancer, particularly among non-smokers. In the Calgary area, many homes exceed Health Canadas recommended limits, highlighting the need for professional assessment.
We provide structured radon testing and mitigation services for residential properties. Health Canada recommends long-term testing for at least 91 days to capture seasonal variation, and we also offer short-term 96-hour testing for real estate transactions using C-NRPP certified technicians and calibrated equipment. When elevated levels are detected, we install sub-slab depressurization systems that create negative pressure beneath the foundation and safely vent radon outdoors, reducing concentrations by up to 95 percent. Our quality assurance process includes sealing entry points, documenting installation 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 pricing, and a 10-year warranty across Calgary and surrounding areas.

We provide professional radon testing to determine indoor levels in residential properties. Radon is a colourless, odourless gas and the second leading cause of lung cancer in Canada. It enters through foundation cracks, mortar joints, and other structural openings. We offer short-term and long-term testing options for accurate measurement. 
We provide professional radon mitigation for homes with elevated radon levels in the Calgary region. Common DIY approaches such as sealing foundation cracks or increasing ventilation are not sufficient solutions. Our approach uses sub-slab depressurization to draw soil gas away before it enters living spaces, reducing radon levels by up to 95 percent. We follow a structured process including inspection, installation, system balancing, monitoring, and quality assurance checks.
