THE HIGHEST-RADON CITY IN CANADA.
Wind Rose tests, mitigates, and backs it with Red Seal trade credentials.
REGINA, BY THE NUMBERS.
Regina has the highest radon prevalence of any major city in Canada — Health Canada survey data has repeatedly found about 50% of Regina homes test above the 200 Bq/m³ residential action level. Across Saskatchewan as a whole the number is closer to 16%. Nationally it sits around 7%. Regina is the outlier, and the geography is the reason: uranium-rich prairie soil, a clay-heavy water table that traps gas under foundations, and a winter that keeps Regina basements closed and ventilation low for six months of the year.
The practical version of that data is this: in any given Regina neighborhood, roughly one in two homes is above the action level Health Canada says calls for mitigation. The homeowner does not know which side of that coin their home sits on until they test. Wind Rose's radon testing is the long-term Health Canada protocol — 91 days of continuous measurement during the closed-house season, ending with a written Bq/m³ report.
If the test result is above 200, mitigation is the next step. The proven approach for Regina foundations — full basement, slab-on-grade, mixed — is sub-slab depressurization. Wind Rose designs and installs the system, runs the post-mitigation verification test that C-NRPP protocol calls for, and adjusts the system on its own ticket if the home does not clear to spec.
The heating side of Wind Rose runs in the same basements as the radon work. Boilers, hydronic heating, gas-fitting, and commercial plumbing all sit on the same trade card. One named tradesperson — Lawrence Kessler, Red Seal and C-NRPP — for radon, boilers, gas, and plumbing in the same home. That combination is uncontested in Regina.

The Regina credential stack
C-NRPP Certified Radon Specialist
The Canadian National Radon Proficiency Program is the national credential Health Canada points to for compliant radon testing and mitigation work. Wind Rose holds it; most Regina mechanical shops do not.
Canadian National Radon Proficiency Program
Red Seal Plumber
The Red Seal is Canada's interprovincial trade endorsement — issued after a full apprenticeship and a national exam. It's the highest plumbing credential in the country and it's what authorizes Wind Rose to install and service mechanical plumbing systems end-to-end.
Interprovincial Red Seal Program
Red Seal Gas Fitter
Same standard as the plumber endorsement, applied to natural gas. Combined with the plumbing credential, this is what makes boiler installs, gas-fitting, and hydronic work doable in-house — no subcontracting the gas side of a boiler job.

Regina questions
Why is Regina so much higher for radon than the rest of Canada?
Three reasons. The prairie soil under Regina is uranium-rich. The water table is clay-heavy, which traps gas under the foundation rather than letting it disperse. And the six-month Regina winter keeps homes closed and ventilation low, which lets indoor radon concentrations build over months instead of dissipating. Geography is destiny on this one — Wind Rose addresses what geography hands the city.
How much does radon testing cost in Regina specifically?
Wind Rose's long-term Health Canada–protocol radon test starts at $325 in Regina, including device deployment, retrieval, and the written Bq/m³ report. Short-term radon tests on a real-estate timeline are priced separately.
What does a typical Regina radon mitigation system look like?
Sub-slab depressurization is the most common approach for Regina homes. A suction pipe is cut through the basement slab, sealed at the slab penetration, routed to an in-line fan (typically mounted outside the conditioned space), and discharged above the roofline. The fan runs continuously, pulling radon out from under the slab before it can move into the living space. A standard residential install is typically a one-day job.
Why are winter radon levels higher in Regina homes?
Two reasons. The home is closed up for six months — windows stay shut, ventilation drops, and indoor air recirculates. Second, the warmer indoor air relative to the frozen ground creates a stronger stack effect that actively pulls soil gas up through the slab. Both factors push winter radon readings higher than summer readings in the same home, which is why Health Canada's long-term test runs during the closed-house season.
Does the City of Regina require radon testing in new construction?
Saskatchewan's building code requires new homes built since 2014 to include a rough-in for radon mitigation — the suction point and pipe stack are pre-installed even if the active fan is not. Testing the completed home is still the only way to know whether the fan needs to be added. Wind Rose tests new construction on the same Health Canada protocol as older homes.
Can one contractor handle both my radon and my boiler in Regina?
Wind Rose can. That's the whole point — a Red Seal mechanical contractor with C-NRPP radon certification is a credential combination no other Regina shop carries. Radon test, mitigation install, boiler service, gas-fitting, and commercial plumbing all run on one job ticket from one named trade.
