Radon Testing & Mitigation in Didsbury, Alberta
Didsbury has established homes, and many have been renovated over the years. Renovated floors, finished basements and added rooms all change how radon behaves, so older results may no longer apply.

What radon means for Didsbury 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 Didsbury.
Homes in Didsbury
Didsbury has established streets and newer areas. Older homes may have partial basements, crawlspaces, additions and finished lower levels, and newer homes may be full-basement builds. Acreages around town can add shops and outbuildings.
What to know in Didsbury
Renovations can open or close paths for radon: new slabs, relocated drains and finished walls change both entry points and ventilation. Retest after major work, and consider retesting about every two years if your result is close to the guideline.
I renovated my basement. Do I need a new test?
Yes. A renovated foundation can read differently, so test after the work is finished. A result from before the renovation does not describe the house as it is now.

Radon testing in Didsbury: established homes and renovations
Renovated basements
We test the finished space and note new drains, slabs and sumps. If walls or floors were finished over cracks, the cracks still matter. Radon changes from day to day, so a proper test runs at least 91 days.
Older foundations
Partial basements and crawlspaces are considered when we choose placement, and we keep the detector 30 cm or more off the floor and away from exterior walls. Every test is set up and read by C-NRPP certified professionals.
Buying an older home in Didsbury
Radon is not part of a standard home inspection. Short-term tests are available if you need a quick answer during a sale, and buyers and sellers use them for a first reading. A short test is only a snapshot, so follow it with a 91-day test, which you can start before listing or right after possession. 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 Didsbury homes with finished basements
Routing through finished space
We look for closets, utility rooms and existing chases so the pipe can run from the suction point to the side of the house with little drywall work. Every system is designed and installed by C-NRPP certified professionals.
Sealing old openings
Cracks, old sumps, drains and gaps around pipes are sealed so the fan pulls from the soil, not from the basement air.
Gauge and retest
We retest to confirm the number dropped. Health Canada recommends retesting at regular intervals, and we suggest about every two years where levels warrant it. 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.
