Winnipeg radon questions, answered straight
The questions homeowners ask before booking. More on the full FAQ page.
Is radon actually a problem in Winnipeg? +
The local data says it deserves attention. In Take Action on Radon's Winnipeg 100 Test Kit Challenge community report, 30% of homes tested came back above Health Canada's 200 Bq/m3 guideline. Winnipeg's clay soils crack as they dry, the housing stock leans heavily on full-depth basements, and sealed winter homes let radon accumulate. None of that means your house is high. It means testing is the only way to know.
How quickly will someone get back to me? +
Our phone is answered by voicemail, and we are upfront about that. Leave a message at (431) 444-1142 and we will get back to you, with a same-day callback for most inquiries received during business hours, Monday to Friday 8:00 AM to 6:00 PM and Saturday 9:00 AM to 3:00 PM. Messages that mention an active real estate deadline get priority callback.
What should I budget for radon work? +
Typical Winnipeg pricing runs $2,400 to $3,800 for a standard mitigation system install. Professional measurement typically runs $150 to $350, and long-term test kits cost about $40 to $60. Those are market ranges, not quotes. The honest number for your home depends on your foundation, sump setup, and where a vent pipe can run, which is exactly what a callback and site assessment sort out.
Should I wait until spring to deal with radon? +
The opposite. Winter is the best time to act on radon in Winnipeg. Cold weather strengthens the stack effect that pulls soil gas into basements, and closed-up homes let it accumulate, so a test run through the heating season captures your realistic peak levels. Health Canada recommends a long-term test of at least 91 days, ideally in fall or winter. Mitigation installs happen year-round.
Do you handle radon for home sales and purchases? +
Yes. Real estate is where radon timelines get tight, so transaction-related messages get priority callback. We work with buyers who want a property measured before a condition date, sellers who want to get ahead of the question before listing, and agents coordinating either side. Short-term measurement protocols designed for transactions make it possible to get usable numbers inside most deal windows.
How do I know a mitigation system actually worked? +
You measure. That is the whole answer. Health Canada notes that properly installed sub-slab depressurization systems typically reduce radon by up to 90%, but the proof for your house is a post-mitigation test comparing your new level against the 200 Bq/m3 guideline. We recommend a follow-up test after every install, and periodic retesting after that, so the system's performance is documented rather than assumed.
Not sure where to start? Most first calls are five minutes: your neighbourhood, your house, and whether testing or mitigation is the right next step.

Winnipeg sits on Red River Valley clay, the famous gumbo that shrinks and cracks as it dries every summer, opening seasonal pathways for soil gas around foundations. The housing stock leans on full-depth basements more than almost any Canadian city, which puts rec rooms, bedrooms, and home offices in direct contact with the soil where radon enters. Sump pits and weeping tile are everywhere because of the water table, and both connect straight to the ground under the slab.
Then there is winter. From November through March, homes stay sealed and the indoor-outdoor temperature gap drives stack effect, the gentle vacuum that pulls soil gas up into basements. That is why radon readings peak in winter, why Health Canada recommends testing through the heating season, and why a low summer reading does not settle the question.
Every neighbourhood wears this differently. Our area pages cover the housing stock and radon context street by street, from postwar bungalows in East Kildonan to the river-lot homes of Charleswood.
Common Winnipeg radon situations
- Never tested and the kids' bedrooms are in the finished basement
- Test came back over 200 Bq/m3 and you want a real plan, not a scare pitch
- Buying or selling with a radon clause and a condition date that will not wait
- Open sump pit in the laundry room and you have read what that means
- Planning a basement reno and want radon handled before the drywall goes up
- Neighbour tested high and now the whole street is wondering
