Radon Mitigation Winnipeg
Sub-slab depressurization systems for Winnipeg homes, designed and installed following Health Canada mitigation protocols.
Need radon mitigation in Winnipeg?
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.
Common signs you need this service
- My long-term test came back over 200 Bq/m3 and I don't know what to do next
- The house we're buying tested high and we want mitigation lined up before possession
- Our basement is fully finished and I'm worried the install will tear it apart
- We have an open sump pit and the readings are highest right beside it
- I caulked the floor cracks myself and the numbers barely moved
- My digital monitor spikes every winter and settles down in summer
- I got one mitigation quote and want to understand what fair Winnipeg pricing looks like
How we handle it
- Call (431) 444-1142 or send the quote form. Leave a message and we will get back to you, same-day callback for most inquiries.
- On-site assessment: foundation type, slab condition, sump and weeping tile layout, and where the suction point and fan can run with the least disruption.
- Written quote with the system layout explained, so you know exactly what is being installed and why.
- Installation day: suction point cored through the slab, sealed piping to the fan and discharge point, sump lid sealed if needed, system labelled with a u-tube manometer installed.
- Post-mitigation verification: a follow-up radon test after the system has run, because the number in your living space is the result that matters.
- Guidance on long-term retesting through a heating season to confirm the system holds through Winnipeg's worst months.
Pricing
Typical Winnipeg pricing runs $2,400 to $3,800 for a standard sub-slab depressurization install, depending on foundation, slab condition, and finishing. That is the Winnipeg market range, not a quote. Your written number is confirmed before any work is booked, so there are no surprises on the bill.
How quickly can we get there?
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
- With Take Action on Radon's Winnipeg 100 Test Kit Challenge community report finding 30% of Winnipeg homes tested above 200 Bq/m3, mitigation is routine work here, not an exotic repair.
- Winnipeg gumbo clay shrinks and cracks as it dries, opening gaps at slab edges and around footings that become soil gas pathways, which is why sealing alone rarely fixes a radon problem.
- Full-depth basements are the dominant housing pattern, from postwar bungalows to 1960s-80s suburbs, so the living space most families use daily sits directly on the radon entry level.
- Sump pits and weeping tile are everywhere in Winnipeg because of the water table. An open pit undercuts a mitigation system, so sealed, serviceable lids are a standard part of installs here.
- Winter stack effect is the stress test: systems are designed for heating-season conditions, when sealed houses and big indoor-outdoor temperature differences pull hardest on the soil beneath the slab.

Questions Winnipeg homeowners ask us
How much does radon mitigation cost in Winnipeg?
Typical Winnipeg pricing runs $2,400 to $3,800 for a standard sub-slab depressurization system, installed and verified. Where a house lands in that range depends on foundation type, slab thickness and condition, whether the sump pit needs a sealed lid, how far the piping has to run, and how much basement finishing has to be worked around. Unusually large footprints or slabs with poor air movement underneath can need a second suction point, which adds cost. Treat any quote far below this range with the same suspicion as one far above it.
How much will a mitigation system actually reduce my radon level?
Health Canada reports that properly installed sub-slab depressurization systems typically reduce radon by up to 90%. A home at 800 Bq/m3 can realistically end up well under the 200 Bq/m3 guideline. No honest provider promises a specific final number before install, because sub-slab conditions vary house to house, and no system eliminates radon entirely since outdoor air itself contains a small amount. That is why every install should end with a follow-up test: the verified post-mitigation reading, not the sales pitch, is the proof the system works.
Do radon mitigators need to be C-NRPP certified?
Radon mitigation in Canada follows the C-NRPP (Canadian National Radon Proficiency Program) framework. Mitigation professionals hold CRMT certification, measurement professionals hold CRT certification, and Health Canada publishes the mitigation protocols the industry works to. When you book through us, work is performed following Health Canada mitigation protocols: suction point diagnostics, sealed system piping, proper fan placement and discharge, system labelling, and post-mitigation verification testing. Whoever you hire, ask them to walk you through how their install follows these standards, and expect a clear answer.
Will mitigation work in a finished basement?
Yes, and this is one of the most common Winnipeg scenarios, since so many basements here are finished living space. The suction point is usually placed in an unfinished corner, a utility or furnace room, or inside a closet, and piping is routed to keep drywall cutting to a minimum. Where the sump pit is accessible, it often serves as the suction point with a sealed lid, which avoids coring the slab in finished areas entirely. The assessment visit is where we map this out, so you see the exact route before anything is cut.
How quickly should I act on a high radon test?
Health Canada's advice is that the higher the level, the sooner you should act. A result moderately above 200 Bq/m3 is not an evacuation, radon risk builds over years of exposure, not days, but it also should not sit on a to-do list for another decade. A result several times the guideline deserves prompt attention. The practical path: confirm with a proper measurement if you have not already, get a mitigation assessment booked, and have the system installed and verified before the next heating season locks the house up again.
What does a radon mitigation system look like day to day?
A white or grey pipe, roughly downspout-sized, running from your basement slab to an inline fan and then to a discharge point above the roofline or at an approved exterior location. The fan runs continuously and most homeowners describe the sound as a soft hum, quieter than a furnace fan, and it draws about as much power as a light bulb left on. The u-tube manometer on the pipe shows liquid at two different heights when the fan is pulling suction. Glance at it a few times a year, that is the entire maintenance routine between retests.
