Radon Testing & Mitigation in Windsor, ON
Property owners in Windsor usually come to radon testing and mitigation one of three ways: a letter arrived, a deal demands it, or something failed. All three are easier with local help already lined up.
Radon — the radioactive soil gas — is the second-leading cause of lung cancer in Canada, and the only way to know a building’s level is to measure it. Health Canada’s guideline is 200 Bq/m³; large swaths of the Prairies, interior BC, New Brunswick and pockets of every province routinely test above it. Workplaces are increasingly expected to test under occupational health duties, and daycares in several jurisdictions must.
How it works in Ontario
Jurisdiction matters: in Ontario, the Ontario Building Code (O. Reg. 332/12) governs, and the power to inspect, approve or prosecute rests with the municipal building department. We scope every job against their current requirements.
Radon Testing & Mitigation for Windsor properties
The local context matters here. In Windsor, the Residential Rental Licensing by-law for wards 1 and 2 near the University of Windsor requires inspections before a licence issues, and the city’s older housing means aluminum wiring assessments are a frequent insurer demand.
Most Windsor requests reach us from one of four directions: a transaction, an insurer condition, a municipal letter, or a board meeting where someone finally asked when this was last done.
Landlord and employer angles
Tenant-occupied basements are exactly the high-exposure scenario; testing rental units is fast becoming the professional standard, and some jurisdictions are moving toward mandating it. Federal workplaces and provincially regulated employers carry testing expectations under general duty clauses.
The process
Here is how the engagement typically runs for Windsor properties:
- Tell us the building type, occupancy and whether a transaction deadline exists.
- Approved long-term detectors are placed (or a certified measurement pro attends).
- The lab result determines whether mitigation is indicated.
- A certified mitigator designs and installs the system.
- Post-mitigation testing verifies the reduction and documents it.
One enquiry gets you the requirement mapped, the right Windsor-area specialist matched, and the documentation handled end to end.
Frequently asked questions
Do apartments need testing?
Ground-contact and basement units, yes; upper floors test lower but towers with parkades can surprise. Landlords testing proactively hold the strong position with tenants and regulators.
What radon level requires action?
Health Canada recommends remediating above 200 Bq/m³ — within 2 years at 200–600, within 1 year above 600. There is no “safe” floor; many owners mitigate below 200 for occupied basements.
Who enforces radon testing and mitigation requirements in Windsor?
Day to day, enforcement in Windsor runs through the municipal officials (building, fire prevention, by-law) with the municipal building department as the provincial authority behind them under the Ontario Building Code (O. Reg. 332/12). Our local partners deal with both routinely.
