The most definitive sign is a radon test result showing levels above Health Canada’s guideline of 200 Bq/m³. Radon is odourless and invisible, so testing is the only way to detect it. If your home’s radon levels are high, even slightly above the threshold, it’s time to seriously consider radon removal in Calgary to protect your family’s long-term health.
Your Home has a Basement or Crawl Space
Homes with basements or crawl spaces are particularly vulnerable, as radon gas seeps up from the soil. If your living or sleeping areas are located in these lower parts of the house, the exposure risk increases significantly, especially during colder months when homes are sealed tight.
You’ve Made Recent Energy Upgrades
While energy-efficient homes are excellent for reducing utility costs, they also restrict airflow. New windows, insulation, and sealed foundations can inadvertently trap radon inside. If you’ve upgraded your home without enhancing ventilation, you may need to reassess your indoor air quality.
Neighbours have Reported High Radon Levels
Radon is geographically inconsistent but not random. If nearby homes have recorded elevated readings, yours could be affected too, even if you haven’t tested yet. It’s a strong indication to test your property and act accordingly.
Persistent Respiratory Issues
Long-term radon exposure is the second leading cause of lung cancer in Canada after smoking. Symptoms like chronic coughing, chest tightness, wheezing, or shortness of breath, especially in non-smokers, should not be ignored. While these symptoms alone don’t confirm radon exposure, they warrant investigation.
You’ve Recently Renovated Your Home
Major renovations that disturb the foundation or alter air circulation, like adding a sump pump or remodelling a basement, can change how radon enters and accumulates in your home. After such changes, it’s wise to retest for radon, even if previous levels were safe.
Your Home Uses Gas Appliances
While not a direct cause of radon, homes with gas appliances often feature sealed environments similar to those used with tankless water heaters in Calgary, potentially contributing to reduced roof ventilation. When combined with other risk factors, the need for radon mitigation becomes more pressing.
Radon may be silent, but its health risks are not. If any of the signs above apply to your home, consider testing and, if necessary, initiating radon removal in Calgary. Early intervention not only safeguards your home’s air quality but could also be a life-saving decision for everyone living under your roof.
