Understanding radon gas and where it comes from
Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in rocks and soil. It’s clear, odourless, and tasteless—making it completely undetectable without special testing equipment. As radon accumulates in enclosed spaces, especially basements and lower floors, it can reach concentrations that pose serious health concerns.
Why radon is common in Calgary homes
Calgary’s geology is rich in uranium-bearing minerals, which means radon can easily seep up into homes through foundational cracks and gaps. This is worsened during cold months when homes are sealed tightly and air pressure differentials naturally pull radon gases in from the soil. Many buildings in Calgary were constructed long before radon risks were widely understood, leaving them particularly vulnerable. According to the Canadian Radon Association, nearly 1 in 6 homes in Canada exceed Health Canada’s recommended radon limit of 200 Bq/m³.
Health Canada’s position on acceptable radon levels
Health Canada has identified radon as the second-leading cause of lung cancer in the country after smoking. The department recommends that any home testing above 200 Bq/m³ should undergo radon mitigation to bring exposure within safe limits. Unlike other indoor pollutants, radon exposure builds quietly over time—posing elevated risk to both smokers and non-smokers alike. Recognizing the long-term risks, many Canadian homeowners are now proactively installing radon mitigation systems to protect their families’ respiratory health.
Protecting your household starts with awareness—know what’s in your air before it’s too late.
Signs Your Home Has High Radon Levels
Radon gas can build up in finished basements, making professional radon reduction systems essential for Calgary homeowners.
If you’re unsure whether your Calgary home contains dangerous radon levels, you’re not alone—many homeowners aren’t aware until it’s too late. Because radon gas is invisible and odorless, there are no immediate physical symptoms. That makes understanding risk factors and knowing when to test absolutely vital. Here’s how to recognize potential red flags before they jeopardize your health.
Radon doesn't fix itself. If your levels are above 200 Bq/m³, professional radon removal in Calgary is the only proven solution. Calgary Radon Detection installs mitigation systems that lower radon levels by up to 99%. Request your free estimate.
Why radon is undetectable without testing
Unlike carbon monoxide or smoke, radon doesn’t trigger alarms. It slowly builds up over time, especially in poorly ventilated lower levels. No scent, no taste, and no color makes it undetectable through senses alone. Only professional-grade testing equipment can determine if buildup has reached hazardous levels. Delaying testing increases exposure, especially over colder months when windows are closed and air circulation is limited.
Common household risk factors (e.g., finished basements, location in Calgary)
Certain features make a home more prone to radon intrusion:
- Finished or livable basements
- Older foundations with cracks or drains
- Homes located in south Calgary and other radon-prone zones
- Properties built before radon-resistant construction standards were introduced
- Insufficient mechanical ventilation systems
Health Canada confirms that Calgary has some of the highest indoor radon readings in Western Canada.
Personal stories from Calgary residents discovering high radon
“We didn’t notice anything until we did a test and found levels three times over the limit.” – Calgary homeowner
This homeowner’s story is a common one across Calgary. Many residents report living for years with elevated radon without any awareness—until proactive testing reveals the danger hovering beneath their homes.
Unseen doesn’t mean safe—recognize the warning signs and make informed choices.
Radon Testing Methods for Calgary Homes
A certified specialist from Calgary Radon Detection prepares to install a radon reduction system in a Calgary home.
If you’re looking to install a radon reduction system in Calgary, it all starts with accurate radon gas testing. Homeowners and property managers need to understand the testing options available—and why professional-grade testing offers long-term value and safety. With proper diagnostics, mitigation can be tailored to your home’s layout, air pressure differentials, and soil conditions.
Short-term vs long-term test kits
Short-term test kits (2–7 days) provide a quick snapshot but can be affected by temporary environmental conditions like humidity or snowmelt. Long-term test kits (90+ days) are more accurate, capturing radon fluctuations across multiple weather cycles and heating periods. Health Canada recommends long-term testing for definitive conclusions, particularly in Alberta’s climate.
Why professional testing is more reliable in Calgary’s conditions
Professionally administered radon testing accounts for Calgary-specific air pressure variations and geological features. Technicians use calibrated digital detectors and follow precise placement guidelines—usually in the lowest occupied level of the home. This approach is superior to generic test kits, which are susceptible to user error and may underrepresent actual exposure.
Calgary Radon Detection offers free professional tests for homeowners — results in as little as 10 days!
Our systems also factor in ventilation patterns, seasonal sealing practices, and building materials—ensuring test accuracy before designing a mitigation plan.
When and how often you should test
Testing should ideally be done every two to five years, or anytime you remodel your basement, upgrade flooring, or seal foundation gaps. New homeowners should prioritize testing in the first month of occupancy, while landlords in multi-unit properties should conduct periodic assessments to remain compliant with evolving Canadian radon regulations.

How to Choose the Right Radon Reduction System
If you’re a Calgary homeowner concerned about basement radon exposure, installing the right radon reduction system can decrease indoor radon levels by over 90%. Choosing between passive and active mitigation solutions—and understanding the implications for your specific property type—ensures long-term health protection and compliance with Canadian radon regulations.
Passive vs active systems: what’s the difference?
Passive radon systems rely on natural air flow and pressure differentials to expel radon gas from beneath the foundation. These systems are more common in new builds where proper preparation has been made in the slab. However, in Alberta’s colder months, passive systems may fall short. Active systems, on the other hand, use electric fans to continuously pull radon from beneath the home and vent it safely outdoors—making them significantly more reliable, particularly for older Calgary homes or those with existing radon problems.
Sub-slab depressurization and other methods
Sub-slab depressurization (SSD) is the gold standard in radon mitigation and is preferred throughout most Calgary homes due to our prevalent basement construction. SSD involves creating a vacuum underneath your foundation slab by inserting a pipe and fan system. Other methods—like crawl space ventilation or sealing entry points—are less effective as standalones but may be used in combination with SSD. According to Health Canada:
“Sub-slab depressurization is the most effective and reliable radon reduction technique.”
Working with certified radon system installers in Calgary
Selecting a certified radon mitigation professional ensures the system is correctly designed for your property’s foundation type, footprint, and radon level. Calgary Radon Detection technicians follow Canadian National Radon Proficiency Program (C-NRPP) standards to install tailored strategies that meet or exceed provincial building code requirements.
Tip: Before installation, book a professional radon gas test to confirm levels and evaluate system suitability.
Cost to Install a Radon Mitigation System in Calgary

Installation Process and Long-Term Maintenance
Thinking about radon system installation and ongoing upkeep? Calgary homeowners deserve a seamless experience—from install day to yearly follow-ups. Here’s what you can expect from reputable radon system professionals who meet Canadian safety guidelines.
What to expect on install day
A standard radon mitigation installation in Calgary generally takes less than a day. The technician begins with site review and layout confirmation, followed by drilling through the slab, inserting the vent pipe, installing the inline radon fan, and sealing all penetrations. Electric wiring is completed, and the system is tested for suction and airflow. CLEAN-UP is thorough, and the home is left as found. According to Calgary Radon Detection:
“We complete most residential installations in a single day with little to no disruption to household routines.”
Yearly radon system maintenance checklist
To maintain system performance year after year, perform an annual check that includes:
- Testing indoor radon levels with a calibrated detector
- Inspecting the manometer to verify pressure flow
- Listening for unusual fan noise or vibration
- Cleaning debris from vent termination outdoors
- Checking seals around pipes and slab penetrations
Professional maintenance services from Calgary Radon Detection include full inspection reports and C-NRPP-compliant testing add-ons.
Importance of post-installation radon monitoring
Radon levels can fluctuate seasonally, especially during Calgary’s long winters when homes are sealed tighter. That’s why post-installation testing is critical. Health Canada recommends annual checks to ensure levels remain below the 200 Bq/m³ action threshold. Ongoing detection helps spot fan failures or seal breakdowns early.
Pro-tip: Install a continuous radon monitor for real-time peace of mind and easy reporting.
Local Radon Guidelines and What Calgary Homeowners Need to Know
Staying compliant with Calgary’s radon regulations protects your health—and your home’s value. From Health Canada action levels to Alberta-specific construction code requirements, local homeowners and property managers must understand the official radon reduction framework.
Health Canada’s recommended radon levels
Health Canada advises all Canadians to mitigate if a long-term radon test reveals levels exceeding 200 Bq/m³. In Calgary—where over 1 in 6 homes test above safe limits—this guidance is more than precautionary; it’s essential.
Building code requirements in Alberta
Since 2015, the Alberta Building Code has mandated “radon rough-ins” for all new residential construction in affected zones, which includes most of Southern Alberta. This includes perforated pipe runs and vertical vent shafts. However, these features must still be converted into active systems to guarantee safety when radon levels are high.
City of Calgary recommendations and rebates (if any)
The City of Calgary actively supports radon awareness through campaigns and local resources, although direct rebates may vary annually. Some health regions have piloted subsidy programs for testing and mitigation—check with local environmental health offices for current options.
Official advice: “New homes in Calgary are strongly encouraged to include radon mitigation preparation, even if levels aren’t yet tested.”
