Radon Services in Winnipeg
From a first test to a verified mitigation system, every radon service we offer across Winnipeg and the surrounding communities.
Radon work in Winnipeg follows one honest sequence: measure, mitigate if the number justifies it, then measure again to prove the fix. Most of what we arrange is the same handful of jobs: radon testing, radon mitigation, real estate radon testing on tight condition dates, and crawlspace and sump pit work in the older housing stock. Some of it is more involved: split-foundation homes with additions, commercial buildings, and systems that need a second suction point to cover a footing-divided slab. Whatever the situation, the pages below show typical Winnipeg market pricing, response expectations, and what actually happens on the job.
Quotes are free by phone or form, and we set expectations honestly: the phone is answered by voicemail, and most messages get a same-day callback during business hours.
Our Winnipeg radon services
Radon Testing
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.
Radon Mitigation
A confirmed radon result over 200 Bq/m3 is a fixable problem. The standard fix is active sub-slab depressurization: a suction point cored through the basement slab, sealed piping run to the exterior or up through the roofline, and a continuously running inline fan that reverses the pressure difference pulling soil gas into your home. Health Canada reports that properly installed sub-slab depressurization systems typically reduce radon by up to 90%, and results are verified with a follow-up test rather than assumed. Winnipeg homes suit this fix well. Full-depth basements give clear suction point options, and the sump pits and weeping tile common across the city can often be incorporated into the system with a sealed lid. Work is performed following Health Canada mitigation protocols, from suction point diagnostics to system labelling and the u-tube manometer that shows the system is pulling. Typical Winnipeg pricing runs $2,400 to $3,800 depending on foundation, slab condition, and basement finishing. Call, leave a message, and we will get back to you, with a same-day callback for most inquiries.
Real Estate Radon Testing
Radon is showing up in more Manitoba real estate deals every year, and it moves on a different clock than everything else about a transaction. Health Canada recommends a long-term test of at least 91 days, but a conditional offer rarely allows more than a week, so real estate testing uses short-term measurement performed under closed-house conditions, following protocols designed for exactly this situation. We work to your deadline: priority callback for urgent real estate deadlines, detectors placed promptly, and results delivered in plain language that buyers, sellers, and agents can act on. With Take Action on Radon's Winnipeg 100 Test Kit Challenge community report finding 30% of Winnipeg homes tested above 200 Bq/m3, a high result is a real possibility, but it is not a deal killer. Mitigation is routine, typically $2,400 to $3,800 in Winnipeg, and often becomes a straightforward negotiation item. Whichever side of the deal you are on, we help you get a defensible number in time.
Commercial Radon Services
Radon is not just a homeowner issue. Offices, daycares, clinics, and multi-unit residential buildings across Winnipeg sit on the same Red River Valley clay as the houses around them, and any occupied space in contact with the ground can accumulate radon. The Health Canada guideline of 200 Bq/m3 applies to indoor air where people spend their time, and employers, landlords, and childcare operators are increasingly adding radon to their due diligence. Commercial measurement is a bigger job than a single home test. Detectors are deployed across ground-contact and lower-level occupied rooms, left in place for a proper measurement window, and reported area by area so you know exactly where any problem lives. If results come over the guideline, we help you plan mitigation, from a single suction point system to multi-point layouts for larger slabs, with work performed following Health Canada mitigation protocols. Call or send the quote form, leave a message, and we will get back to you, same-day callback for most inquiries.
Crawlspace & Sump Radon Control
Sump pits, weeping tile, and crawlspaces are three of the most direct radon pathways in Winnipeg housing, and the city's water table means most basements have at least one of them. An open sump pit is essentially a window into the soil beneath your home. The weeping tile draining into it collects water from around the footing, and soil gas rides the same route. Dirt-floor or partially finished crawlspaces under additions and older homes do the same thing over a larger area. The fixes are well established. Sump pits get sealed, gasketed lids that keep pumps serviceable while closing the air pathway. Exposed crawlspace soil gets a sealed membrane, and where levels demand it, the space under the membrane or slab is depressurized so soil gas vents outside before it can enter. Work is performed following Health Canada mitigation protocols and verified with follow-up testing. Leave a message and we will get back to you, same-day callback for most inquiries.
Post-Mitigation Radon Testing
A radon mitigation system is not a set-and-forget appliance. Fans age, sump configurations change, basements get finished, and Winnipeg's shifting gumbo clay can open new cracks in a slab over the years. The u-tube manometer on your system pipe only proves the fan is pulling suction. It does not tell you what the radon level in your living space actually is. That takes a measurement. Health Canada's guidance is to verify mitigation with a follow-up radon test after installation and to retest periodically and after major renovations. We provide post-mitigation measurement for Winnipeg homes: short-term verification after an install or repair, and long-term confirmation across a heating season, when stack effect pushes radon to its annual peak. If your numbers have crept back above 200 Bq/m3, we help diagnose the cause, whether it is a tired fan, an unsealed sump, or a system that needs another suction point. Leave a message and we will get back to you, same-day callback for most inquiries.
How we work, start to finish
Every radon job in Winnipeg moves through the same four steps. Knowing what each step involves is how you avoid both surprise invoices and unnecessary work.
- 1. Phone or form. You describe your home and situation: neighbourhood, house age, foundation, sump pit, any test result, any deadline. Most callbacks take under ten minutes.
- 2. Measure, unless you already have a defensible number. Health Canada's guidance is a long-term test of at least 91 days, ideally through the heating season. Real estate deals use faster short-term protocols with their limits explained in writing. Nobody should buy a mitigation system off a guess.
- 3. Mitigate what the number justifies. If your result is over 200 Bq/m3, you get an itemized written quote: suction point, fan, pipe routing, electrical, and verification test, each on its own line. The quote you approve is the price you pay, with written change-orders for anything genuinely unforeseeable under the slab.
- 4. Verify. Every mitigation install should end with a post-mitigation test that documents the new level against the guideline. Performance gets proven, not assumed.
That is the entire process. No scare tactics, no add-on packages, and no pressure to mitigate a house that tested at 80 Bq/m3.
Winnipeg conditions that shape radon work here
- Gumbo clay. Red River Valley clay shrinks and cracks as it dries each summer, opening seasonal soil-gas pathways around foundations. It also affects how sub-slab air moves, which is why suction-point diagnostics matter before committing to a system layout.
- Full-depth basements everywhere. Winnipeg's housing stock puts finished rec rooms and bedrooms in direct contact with the soil. That is exactly where Health Canada says to measure, in the lowest lived-in level.
- Sump pits and weeping tile. Common here because of the water table, and both are direct connections to the soil. A sealed sump lid is often part of the fix, and an existing pit is often the most efficient suction point for a mitigation system.
- Sealed winters. November through March, homes stay closed and stack effect pulls soil gas in. Winter is when levels peak, when long-term testing is most representative, and when discharge-pipe routing has to account for real cold.
- Additions and split foundations. Older Winnipeg homes often carry additions on their own slab or crawlspace. Split foundations sometimes need more than one suction point, which is a design question, not a surprise charge, when it is caught at assessment.

Frequently asked questions about our Winnipeg radon services
What radon services do you offer in Winnipeg?
Radon testing (long-term and short-term measurement), radon mitigation system design and installation, real estate transaction testing on condition-date timelines, commercial building radon services, crawlspace and sump pit solutions, and post-mitigation verification testing. We serve every Winnipeg neighbourhood plus East St. Paul, West St. Paul, Headingley, Oakbank, Niverville, and Stonewall.
Do you charge to quote a radon job?
No. Phone and form quotes are free. Radon mitigation quotes work well remotely because most of the cost drivers are things you can describe: foundation type, footprint, sump pit, basement finish level, and your test number. Final pricing is confirmed with an on-site assessment before anything is booked, so the number you approve is the number you pay.
What hours are you available?
Monday to Friday 8 AM to 6 PM and Saturday 9 AM to 3 PM. Sunday is closed. The phone is answered by voicemail; messages left during business hours get a same-day callback for most inquiries, and off-hours messages are returned the next business day. The quote form is monitored the same way.
How fast can radon work actually happen in Winnipeg?
Testing starts fast: a detector can usually be placed within a few business days. The measurement itself takes as long as the protocol requires, 91+ days for the long-term tests Health Canada recommends, or a few days for the short-term protocols used in real estate deals. Mitigation installs are typically a one-day job once the assessment and quote are approved. Real estate deadlines get priority scheduling; say so in your message.
Do you serve communities outside Winnipeg?
Yes. East St. Paul, West St. Paul, Headingley, Oakbank, Niverville, and Stonewall are part of the standard service area. Rural properties farther out are case-by-case depending on the schedule that week, with any drive charge quoted upfront so there are no surprises.
Is radon testing worth it if my house is new?
Yes. New homes are not automatically low. Radon levels depend on the soil under the slab, the foundation details, and how the house breathes, not the build year. Newer, tighter homes can actually hold more radon because they exchange less air. Many newer Manitoba homes include a passive radon rough-in under the slab; a test tells you whether it needs to be activated with a fan, which is one of the cheapest mitigation scenarios there is.
Why does Winnipeg have a radon problem in the first place?
Geology and housing stock. The Red River Valley sits on uranium-bearing soils, and radon is the decay product that migrates up through the clay. Winnipeg homes overwhelmingly have full-depth basements in direct contact with that soil, plus sump pits and weeping tile that connect straight to it. Long sealed winters then let radon accumulate indoors. In Take Action on Radon community testing, 30% of participating Winnipeg homes came back above the Health Canada guideline of 200 Bq/m3.
