Radon Mitigation in Edmonton

According to the World Health Organization, Radon levels above 100 Bq/m³ should be reduced to minimize the risk of lung cancer. Radon exposure varies widely—from one home to the next, between neighbourhoods, and across cities and provinces. This makes it crucial for every Edmonton homeowner to test for Radon and take steps to lower elevated levels. Research shows that for every additional 100 Bq/m³ of Radon exposure, the risk of lung cancer increases by 16%—a statistic too serious to ignore.

If your home has high Radon levels, don’t worry—there are proven solutions. Common approaches include increasing ventilation, sealing cracks and gaps, and sub-slab depressurization. However, not all methods are equally effective. For example, sealing cracks typically lowers Radon by about 13%, while ventilation improvements can reduce levels by 25–50%. In contrast, hiring a C-NRPP–certified professional to install a Radon mitigation system can lower Radon levels by up to 95%, making it by far the most reliable solution.

Radon mitigation in Edmonton works the same way as elsewhere in Canada. A certified professional installs a system designed to continuously draw Radon gas from beneath your home and safely vent it outdoors. These systems are the gold standard for reducing Radon levels, offering long-term protection and peace of mind for you and your family.

Step-by-Step Guide to Radon Mitigation in Edmonton

1. Our Certified Radon Mitigation Professionals begin by sealing all accessible gaps and cracks in your slab to make it as airtight as possible.

2. We then perform pressure diagnostics to determine the correct fan size. A specialized in-line fan is installed to create negative pressure beneath your slab, preventing Radon from entering your home and continuously reducing levels.

3. A vent pipe connected to the fan safely directs Radon outdoors, where it dissipates into the atmosphere within 6 feet of the exhaust point.

4. After installation, post-mitigation Radon testing is carried out by the homeowner to confirm the system’s effectiveness.

Many homeowners notice significant Radon reduction within 24 hours, though some homes may take a bit longer to fully vent sub-slab moisture before reaching peak efficiency. Systems are most often installed in the mechanical room, though they can also be connected to an existing sump cavity to avoid extra ground penetrations. In rare cases where a dirt crawlspace is present, we use sub-membrane depressurization, installing a sealed membrane to effectively draw Radon from the space. No matter the method, Great West Radon has the expertise to deliver a successful Radon mitigation system in Edmonton.

You may be wondering about the cost. The good news is that a Radon mitigation system is typically less expensive than replacing your furnace, and it should only be installed by trained, insured, C-NRPP certified professionals—not attempted as a DIY project. In most cases, a system can be installed in just one day.

Following Health Canada’s recommendation, homeowners should retest every five years after mitigation to ensure the system remains effective. The question of “when” is simple: the sooner, the better. Acting quickly helps prevent the DNA-level lung damage that prolonged Radon exposure can cause. With Great West Radon, you’re choosing Radon mitigation Edmonton residents can trust.
