Test First
Radon is a gas that comes up out of the soil and into basements through cracks, sump pits and gaps around pipes. You can't see it or smell it. Health Canada calls it the number one cause of lung cancer in non-smokers, and it's the second leading cause after smoking. Nobody can tell you whether your house is high without a test, and that includes us.
The first step is a long-term radon test of at least three months in the lowest level you use. If the result is over 200 Bq/m3, a sub-slab depressurization system is the usual fix. Winnipeg installers advertise systems from about $1,500 to $3,000; a Regina installer quotes $2,500 to $3,500. The cost page shows where those figures come from and what pushes a job higher.
Sub-slab depressurization puts a pipe through the basement floor and a fan that vents the soil gas outside, and Health Canada says it cuts radon by more than 80% in most homes. We connect you with a certified mitigation professional who looks at your slab, sump and crawl space before quoting.

Learn More →Buyers and sellers rarely have 91 days, so a house deal needs a plan that accounts for what a short test can and can't tell you. We explain the options and point you to your realtor or lawyer for the conditions, since we don't give legal advice.
Learn More →Fans wear out, and Health Canada says the system only works if the fan runs all the time. If yours is rattling, silent or the manometer has gone flat, a professional can check it and quote the repair.

If you haven't done a long-term test, we'll say so before anyone quotes you a system. It slows things down, and it's the only way to know whether you need one.
Certification you can check yourself
Prairie Radon Co isn't certified and doesn't test or install. The professional who quotes your job should hold C-NRPP certification, and you can look them up in C-NRPP's online directory before you sign anything.
Prices with a name attached
We publish what named Winnipeg and Regina installers advertise, and we say who said it. We won't invent a local price for a city where none has been published.
The money help, written out
Lungs Matter, the Manitoba Hydro loan and the Saskatchewan renovation tax credit all have different rules, and two of them require a C-NRPP professional. We lay them out so you can check eligibility before the quote.

Health Canada guideline
Call (204) 555-0173 with your test result, or tell us you haven't tested yet. If you haven't, we'll point you to a long-term test first; if you're over 200 Bq/m3, we'll ask about the house so the right professional gets the call.
An independent certified mitigation professional looks at the basement floor, any sump pit or crawl space, and where a pipe and fan can go. That visit is what sets the scope of the job.
You get a written quote to compare, and Health Canada says a system can usually be installed in less than a day. After it's switched on, a short-term test confirms it's working, then you run a long-term test through the first heating season.
We cover homes in Winnipeg and Brandon in Manitoba, and Regina, Saskatoon, Moose Jaw and Prince Albert in Saskatchewan, plus the towns around them. Of the homes tested in the 2024 Cross-Canada survey, 46.6% in Regina and 37.4% in Winnipeg were at or above 200 Bq/m3, and Saskatoon came in lowest at roughly 1 in 6 tested homes. The same survey found no part of Canada is radon-free, so every town on this list is worth a test.
Yes. Health Canada's guideline is based on the average level over time, so it recommends a long-term test of at least 91 days in the heating season. Short tests and digital monitors are good for screening, but they can't tell you whether a system is worth paying for.
A certified mitigation professional visits the house and looks at the slab, any sump pit or crawl space, and where the pipe and fan can run and vent. Winnipeg installers advertise systems from about $1,500 to $3,000, and a Regina installer quotes $2,500 to $3,500, adding that crawl spaces or multiple suction points can cost much more. Your own price comes only from the written quote after that visit.
We don't publish a set response time, because the professionals are independent and their calendars vary; they'll give you a date when you call. The test itself takes at least 91 days, and Health Canada says a system can usually be installed in less than a day. One Winnipeg installer, Radon Manitoba, adds 20% to its prices for off-season work between November 30 and May 20, so ask about timing when you get your quote.
No. Bq/m3 means becquerels per cubic metre, and 200 Bq/m3 is Health Canada's guideline (about 5.4 pCi/L, the US unit). No law in Manitoba or Saskatchewan requires homeowners to test or mitigate. Above 200, Health Canada recommends fixing it within a year, and it also says no level is considered risk free.
The Canadian Lung Association's Lungs Matter program offers up to $1,500 for lower- and moderate-income households, and it needs a C-NRPP long-term test over 200 and a C-NRPP quote before work starts. In Manitoba, the Manitoba Hydro Home Energy Efficiency Loan covers radon mitigation up to $5,000 over 5 years at 6.2% (O.A.C.). In Saskatchewan, Lung Saskatchewan says radon mitigation counts as an eligible expense for the Home Renovation Tax Credit; confirm that with CRA before you count on it.
No. We're an advertising service that connects homeowners with independent C-NRPP certified professionals, and we don't test or install anything ourselves. Certification in Canada is voluntary and belongs to the individual professional, so check their name in C-NRPP's online directory before you hire them.
After you call, we ask about your test result and the house, then pass the details to an independent certified radon professional who serves your area. They arrange a site visit, work out the scope and give you a written quote before any work starts.
