What is Radon and Why You Should Care in Calgary
If you’re a Calgary homeowner or property manager, understanding radon gas isn’t just optional—it’s essential. With Calgary located in one of Canada’s most affected radon zones, the hidden health risks from this invisible intruder are very real. Learning what radon is, how it forms, and why it’s particularly problematic for Calgary homes can help you take the right steps to protect your family’s respiratory health and indoor air quality year-round.

Understanding radon as a radioactive gas
Radon is a colourless, odourless, naturally occurring radioactive gas formed during the decay of uranium in soil, rock, and water. While it’s harmless outdoors in low concentrations, it becomes a major health threat when trapped inside homes and buildings, where it accumulates and lingers without detection. The gas has no taste or smell, making it impossible to identify without proper testing, such as a radon test kit or continuous radon monitor (CRM).
How radon forms and why it’s a concern in homes
As uranium breaks down underground, radon gas migrates toward the surface and can enter structures through even the tiniest gaps—such as foundation cracks and unsealed sumps. Once inside a home, poor ventilation in areas like basements and crawl spaces allow it to accumulate over time. According to Health Canada, radon is the second leading cause of lung cancer in Canada, especially among non-smokers, with over 3,200 radon-related deaths annually.
Why Calgary homes are particularly at risk
Calgary’s geologic makeup contains naturally high levels of uranium, which increases the production of radon gas. Combined with our cold climate—where people keep windows and doors shut for extended periods—this creates the perfect storm for indoor radon accumulation. Recent government surveys have shown that more than 50% of tested homes in Calgary exceed Health Canada’s radon guideline of 200 Bq/m³, making radon mitigation not just advisable but urgent.

How Radon Enters Calgary Homes

Even if your Calgary home appears airtight, radon gas can still creep in through multiple entry points—undetected for years. Understanding these pathways is key to effective radon mitigation and ensuring your family breathes safe indoor air, especially during Alberta’s long heating seasons when homes are sealed tightly.
Common radon entry points in homes
Radon typically infiltrates your home from the ground up. It seeps in through:
- Cracks in concrete slabs and basement floors
- Gaps around utility penetrations and sump pits
- Construction joints and wall-finish gaps
- Floor drains or unsealed crawl spaces
Since radon gas is under pressure relative to the indoor environment, it naturally flows into areas of lower pressure—your home’s basement or ground levels—unless properly blocked or mitigated.
Why basements are higher risk
Basements are typically the first and worst hit by radon intrusion. With closer contact to soil and limited ventilation, radon easily accumulates here in dangerous concentrations. Properties with full basements or slab-on-grade foundations are particularly vulnerable, especially when constructed without radon barriers. Residents often assume newer homes pose less risk, but modern energy-efficient builds can be more airtight, trapping more radon inside.
Winter vs. summer radon levels in Calgary
Calgary’s frigid winter conditions mean seasonal spikes in radon levels. During winter, homeowners seal windows and reduce ventilation, which limits natural air exchange and traps radon inside. According to Health Canada, radon levels are typically at their highest during the winter months, making this the ideal season for testing. Homes that test below guideline levels in summer may exceed health recommendations by winter without mitigation.
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.

Radon Testing and Removal Methods You Can Trust

When it comes to protecting your Calgary home or property from radon gas, knowing which testing and mitigation methods are certified and effective is crucial. Homeowners and property managers throughout Calgary need reliable, proven strategies—especially since Health Canada recommends remediation at any level over 200 Bq/m³. Calgary Radon Detection uses only certified techniques and C-NRPP professionals to ensure safe air and lasting peace of mind.
Short-term vs. long-term radon testing
Testing is your first line of defense. Short-term radon tests typically last from 2 to 7 days, offering quick snapshots of indoor radon levels. While helpful for initial screening, they can vary due to temperature, humidity, and ventilation. Long-term tests, running 90+ days, provide a more accurate average—often during winter months when Calgary homes are sealed tightly. Certified digital radon monitors deliver reliable results and are highly recommended for both new buyers and current occupants.
How sub-slab depressurization works
Sub-slab depressurization is the most effective and widely used radon mitigation method in Calgary homes. This technique involves drilling a small hole in the basement slab and inserting a PVC pipe that actively draws radon gas from beneath the home’s foundation and vents it safely above the roofline. A quiet, energy-efficient fan creates negative pressure below the slab, preventing radon from entering the living space. C-NRPP certified mitigation ensures the system meets strict national safety guidelines.
Sealing and ventilation options
While sub-slab systems are primary, sealing cracks and improving controlled ventilation are important complementary methods. Sealing basement wall joints, sump pit covers, and floor penetrations reduces radon entry points. Enhanced HRV (heat recovery ventilation) systems can be used to increase fresh air exchange, reducing overall radon concentration—especially in homes that cannot accommodate piping due to layout constraints.

What Does Radon Mitigation Cost in Calgary?

Concerned about the cost of radon removal in your Calgary home? You’re not alone. Many homeowners want to invest smartly in mitigation without overspending. The good news is that radon mitigation in Calgary is not only affordable but delivers measurable health and real estate returns. Here’s what you need to know before booking your system installation.
Average radon removal costs explained
Typical Calgary radon mitigation systems cost between $2,500–$3,800. The final price depends on several factors: the square footage of your basement, the number of suction points needed, the slab thickness, attic or roof venting complexity, and whether the house is a bungalow, two-story, or walkout. Homes with finished basements or limited access may require additional labor and custom solutions.
ROI: home health, resale value, peace of mind
Reducing exposure to radon significantly lowers long-term risk of lung cancer, especially in young children and non-smokers. That’s a priceless health return. But there’s also economic upside: homes in Calgary with documented radon mitigation often enjoy increased buyer confidence, making them more attractive on the resale market. Many buyers now request radon tests during the home inspection stage.
Financing or rebate opportunities in Alberta
While Alberta currently doesn’t mandate mitigation subsidies, seasonal rebates or manufacturer incentives may be available from C-NRPP affiliated contractors or health organizations. Calgary Radon Detection regularly advises clients on accessible mitigation funding and will help homeowners explore cost-effective solutions that don’t sacrifice safety or compliance.
