Commercial Radon Services Winnipeg
Radon measurement and mitigation planning for Winnipeg offices, daycares, clinics, and multi-unit buildings.
Need commercial radon services in Winnipeg?
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.
Common signs you need this service
- We run a daycare and parents are asking whether the building has been tested for radon
- Our staff work in a basement-level office all day and someone raised radon at a safety meeting
- We own a multi-unit building and don't know which suites or floors need testing
- Head office wants radon added to our workplace health and safety program
- Our building is slab-on-grade and we always assumed radon was only a basement problem
- A tenant tested their own suite with a consumer monitor and sent us a screenshot
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.
- Walkthrough and floor plan review to identify occupied ground-contact and lower-level spaces that need detectors.
- Detector deployment across the identified areas, following Health Canada measurement guidance for buildings.
- Measurement window runs with minimal disruption to your operations, then detectors are collected for analysis.
- Area-by-area written report against the 200 Bq/m3 guideline, suitable for boards, head office, or safety committees.
- If any area is over the guideline, we scope mitigation options and sequencing so occupied spaces are addressed first.
Pricing
Assessed per building. For reference, typical Winnipeg professional measurement runs $150 to $350, with larger buildings needing multiple detectors, and residential-scale mitigation systems typically run $2,400 to $3,800, with multi-point commercial layouts scaling from there. 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
- Take Action on Radon's Winnipeg 100 Test Kit Challenge community report found 30% of Winnipeg homes tested above 200 Bq/m3, and commercial buildings stand on the same gas-producing soils as those homes.
- Winnipeg gumbo clay shrinks, swells, and cracks seasonally, stressing slab joints and utility penetrations, which are the main radon entry routes in commercial slabs.
- Winter stack effect is amplified in taller heated buildings, and Winnipeg's long heating season means months of sustained pressure drawing soil gas through the slab.
- Basement and lower-level workspaces are common in Winnipeg's older commercial stock, and those are precisely the spaces where radon concentrates and where staff spend full workdays.

Questions Winnipeg homeowners ask us
Does the 200 Bq/m3 guideline apply to workplaces and commercial buildings?
Health Canada's radon guideline of 200 Bq/m3 is written for indoor air in normal occupancy areas, and Health Canada publishes guidance for measuring radon in public and workplace buildings, not just houses. The practical standard for a daycare room, a basement office, or a ground-floor suite where people spend hours every day is the same: know the number, and act if it is over the guideline. Many organizations now fold radon testing into their occupational health and safety programs, since it is one of the cheapest workplace air quality questions to answer definitively.
How do you test a large or multi-unit building?
With multiple detectors, placed systematically rather than one per building. Measurement focuses on occupied spaces in contact with the ground: basement and ground-floor offices, ground-level suites, daycare rooms, staff areas, and similar spaces. Upper floors are generally lower priority because radon enters from the soil, but lower-level results determine whether wider testing makes sense. Each detector is logged by room, the measurement window runs its course, and the report maps results area by area, so if mitigation is needed you spend money only where the problem actually is.
What does commercial radon work cost in Winnipeg?
Measurement scales with detector count. Typical Winnipeg professional measurement pricing runs $150 to $350, and a multi-room commercial deployment is essentially that model extended across the spaces that need coverage, quoted per building once we see the floor plan. On the mitigation side, typical Winnipeg pricing for a residential-scale sub-slab depressurization system runs $2,400 to $3,800, and larger commercial slabs that need multiple suction points scale up from that baseline. We put real numbers on it after a walkthrough, since slab area and layout drive the design.
Are commercial radon contractors certified?
Commercial radon work in Canada follows the same C-NRPP (Canadian National Radon Proficiency Program) framework as residential work. Measurement professionals hold CRT certification, mitigation professionals hold CRMT certification, and Health Canada publishes the measurement and mitigation protocols that apply to buildings beyond single homes. Work arranged through us is performed following Health Canada protocols, from detector placement through mitigation design and verification testing. For a commercial engagement, it is reasonable to ask any provider how their process follows these standards and to expect that answer in writing.
Will testing or mitigation disrupt our operations?
Testing is close to invisible: small passive detectors sit in the rooms being measured, staff and tenants carry on normally, and the main request is that the detectors stay where they were placed. Collection is a short second visit. Mitigation is more involved, since it means coring through the slab and running sealed piping to a fan and discharge point, but the work is typically staged around your hours, and once running, the system is a quiet fan that needs no attention beyond periodic checks and follow-up testing. Most tenants never notice it.
