Radon Testing Winnipeg
Professional radon measurement for Winnipeg homes, from short-term screening to the 91-day long-term tests Health Canada recommends.
Need radon testing in Winnipeg?
Radon is an invisible, odourless radioactive gas that builds up in basements, and Winnipeg has one of the more serious radon problems in Canada. Take Action on Radon's Winnipeg 100 Test Kit Challenge community report found 30% of Winnipeg homes tested above the Health Canada guideline of 200 Bq/m3. The only way to know your number is to test. We provide professional radon measurement for Winnipeg homes, following Health Canada's guidance of a long-term test of at least 91 days, ideally run through fall and winter when closed windows and stack effect push readings to their annual peak. Winnipeg's full-depth basements, sump pits, and cracking gumbo clay soils give radon plenty of entry routes, so every home deserves its own test rather than a guess based on the neighbour's result. Call or request a quote online, leave a message, and we will get back to you, with a same-day callback for most inquiries.

Typical response: Same-day callback for most inquiries. Messages that mention a real estate deadline get priority callback, and testing visits are usually scheduled within a few business days.
Winnipeg factors that shape this work
- Take Action on Radon's Winnipeg 100 Test Kit Challenge community report found 30% of homes tested above the 200 Bq/m3 guideline, far more than most homeowners expect.
- Red River Valley clay, the famous Winnipeg gumbo, shrinks and cracks as it dries each summer, opening seasonal pathways for soil gas around foundations.
- Cold winters keep homes sealed from November through March and drive stack effect, which pulls soil gas into basements and makes winter the ideal testing season.
- Full-depth basements are the dominant Winnipeg housing pattern, so bedrooms, rec rooms, and home offices often sit right against the soil where radon enters.
- Sump pits and weeping tile are common here because of the water table, and both connect directly to the soil under and around the slab.

Questions Winnipeg homeowners ask us
How much does radon testing cost in Winnipeg?
Typical Winnipeg pricing runs $150 to $350 for professional measurement, which includes proper detector placement, a controlled measurement period, and lab analysis. If you would rather start smaller, long-term do-it-yourself test kits typically run $40 to $60 including lab fees. The professional route makes sense when you need a defensible number, for example before a major renovation or when a first result came back near the 200 Bq/m3 guideline and you want confirmation before spending on mitigation.
How long does a radon test take?
Health Canada recommends a long-term test of at least 91 days, ideally run through fall and winter, because radon levels swing day to day and season to season. A three-month average is the number worth making decisions with. Short-term tests of a few days exist and are useful for quick screening or real estate deadlines, but a low short-term result in July does not rule out a high winter average. If a short-term result is elevated, the next step is either a long-term confirmation or moving straight to mitigation planning.
Do radon testers need to be certified?
Radon work in Canada follows the C-NRPP (Canadian National Radon Proficiency Program) framework. Measurement professionals hold CRT certification and mitigation professionals hold CRMT certification, and Health Canada publishes the measurement protocols the industry works to. When you book through us, testing is performed following Health Canada measurement protocols: detector placement in the lowest lived-in level, proper test duration, and lab analysis are all done the way the framework specifies. It is always fair to ask any radon provider to walk you through how their process follows these standards.
What radon level is considered dangerous?
Health Canada's guideline is 200 Bq/m3 as an annual average in the normal living areas of your home. Above that, Health Canada recommends taking action to reduce the level, and the higher the number, the sooner you should act. There is no level considered completely risk free, since radon is the second leading cause of lung cancer after smoking, but risk scales with concentration and time. In practice, a result under 200 Bq/m3 means retest every few years and after renovations, while a result over it means it is time to look at mitigation.
When is the best time to test for radon in Winnipeg?
Fall and winter. From roughly November through March, Winnipeg homes stay sealed against the cold, and the temperature difference between indoors and outdoors drives stack effect, the pressure imbalance that pulls soil gas up into the basement. That is when radon concentrations are at their annual peak, so a test that spans the heating season captures your worst-case exposure rather than a flattering summer number. If you are reading this in summer, you can still start a 91-day long-term test now, or plan to launch one in October.
