Radon testing is the only way to know whether your Ottawa home has a radon problem. Because radon is invisible and odourless, guessing isn't an option — and radon levels vary dramatically from one house to the next, even on the same street.
Health Canada recommends a long-term radon test of at least 91 days in the lowest lived-in level of your home. Short-term tests (2–7 days) are useful for a quick screening, but a long-term test gives the most accurate picture of your annual exposure, since radon fluctuates with the seasons.
We provide both options: professional short-term screening when you need an answer fast, and Health Canada–standard long-term tests that give you a reliable number to act on. If your result comes back above 200 Bq/m³, we'll walk you through your mitigation options — no pressure.
A Local Challenge We Understand
Ottawa's position over uranium-bearing bedrock means radon levels vary widely across the city. Homes in Kanata, Stittsville, Carp, and the rural west end tend to test higher, but elevated radon has been measured in every Ottawa ward. Health Canada's survey found that a significant percentage of Ottawa homes exceed the 200 Bq/m³ action level. Testing is the only way to know where yours stands.

Frequently Asked Questions
Straight answers to the questions Ottawa homeowners ask us.
What is a safe radon level?
Health Canada's guideline is 200 Bq/m³. Below that, no action is needed. Between 200 and 600 Bq/m³, mitigation is recommended within 2 years. Above 600 Bq/m³, mitigation is recommended within 1 year. There is no truly 'safe' level — lower is always better.
Short-term or long-term test?
A long-term test (91+ days) gives the most accurate picture because radon fluctuates daily and seasonally. A short-term test (2–7 days) is useful for a quick check or real-estate timeline, but should be followed up with a long-term test if results are near or above the guideline.
Where should the radon detector be placed?
In the lowest lived-in level of your home — typically a basement bedroom or family room — away from windows, doors, vents, and humidity. We position it correctly during setup.
How long until I get results?
Short-term results are available within days of returning the detector. Long-term tests require the full 91+ day period plus a few days for lab processing.
Should I test before buying a home in Ottawa?
Yes. Radon testing during a home purchase gives you leverage to negotiate mitigation, or peace of mind that the home is safe. Ask us about short-term testing for real-estate timelines.
