Radon Testing & Mitigation in Banff, Alberta
Banff’s townsite sits inside a national park, with older homes, duplexes and other compact buildings. Small spaces and attached buildings both shape how we test and how we fix radon.

Health Canada recommends action when the long-term average is above 200 Bq/m³. Short tests are only a snapshot. 1 pCi/L ≈ 37 Bq/m³.
What radon means for Banff homeowners
Radon is a natural radioactive gas that forms when uranium in soil and rock breaks down. It seeps into homes through cracks, drains and gaps, you can’t see or smell it, and breathing it for many years raises your risk of lung cancer. Testing is the only way to know your level. Here is what matters for homes in Banff.
Homes in Banff
Banff has older homes, duplexes and other attached buildings, and many are compact. Whatever the type, we recommend testing the lowest level.
What to know in Banff
Because Banff is inside a national park, exterior work such as a vent pipe may need approval from the Town of Banff. We explain what is likely to apply to your property before any work starts.
Does a small or older home need a radon test?
Yes. Size and age do not predict radon, so a small or older home can be as high as a large one. Test the lowest level of the building.

Radon testing in Banff: compact and attached homes
Duplexes and attached homes
Each unit is tested separately, because each has its own contact with the soil and its own airflow. A neighbour’s result does not describe your side of the building. Radon changes from day to day, so a proper test runs at least 91 days.
Basements and crawlspaces
Buildings may have full basements, crawlspaces or slabs on grade. We test the lowest level and consider each foundation under the building. Every test is set up and read by C-NRPP certified professionals.
Older and compact homes
With less space, the detector still needs to be 30 cm or more off the floor and away from windows, doors and vents. We choose the right room on the day. Health Canada’s guideline is 200 Bq/m³ (5.4 pCi/L), and 1 pCi/L equals 37 Bq/m³. Above that, it recommends reducing radon within one year, sooner if the level is higher.
Radon mitigation in Banff’s compact homes
Tidy pipe routes
In compact homes the pipe route and fan spot need planning to stay out of the way. We use closets, utility rooms and existing chases where possible. Every system is designed and installed by C-NRPP certified professionals.
Attached buildings
In attached buildings, the owner or board may need to approve a system, so we explain the result and options in plain language to everyone involved.
Gauge and retest
A manometer shows the fan is running, and a 91-day retest after install confirms the new number. In shared buildings, we give the owner or manager a copy of the result. In most homes a system can reduce radon by up to 95%.

Thinking about a DIY radon test?What to know before you buy a kit
- Choose a long-term testHealth Canada recommends testing for at least 91 days, ideally 3 to 12 months. Short-term kits, including many library kits, only give a rough idea and aren’t appropriate for deciding on mitigation.
- Use an approved deviceHealth Canada recommends long-term devices that have passed C-NRPP performance testing. For electronic monitors, it strongly recommends only devices on the C-NRPP consumer list.
- Know the kit typesAlpha track detectors and electret ion chambers are sent to a lab for results. Electronic radon monitors show readings on a screen or app, but check that they store at least three months of data.
- Place it correctlyUse a bedroom, living room or office on the lowest lived-in level, at least 30 cm above the floor and 30 cm from walls, and 1 m from windows, doors and vents. Avoid kitchens, bathrooms, laundry rooms, sump holes and foundation cracks. One detector is enough.
- Follow the instructions exactlyDon’t move or tamper with the device. Mail lab kits back promptly and before the expiry date. If a device is dropped or damaged, repeat the test with a new one.
