Protect Your Home. Protect Your Family.
Radon is a colourless, odourless radioactive gas that occurs naturally in the ground. It can enter homes through foundation cracks, sump pits, floor drains, crawlspaces, and service penetrations.
You cannot see it. You cannot smell it.
Testing is the only way to know.
Health Canada identifies radon as the second leading cause of lung cancer after smoking.
What Is Radon?
Radon is produced by the natural breakdown of uranium in soil and rock. In northern climates like Yellowknife and surrounding NWT communities, homes are tightly constructed to conserve heat — which can allow radon to accumulate indoors.
Radon typically enters through:
Cracks in concrete slabs
Gaps around plumbing penetrations
Sump pits
Crawlspaces
Foundation wall joints
Floor drains
Even newer homes can have elevated levels.
Health Canada Guidelines
Health Canada recommends action if radon levels exceed:
200 Bq/m³ (becquerels per cubic metre)
The only way to determine your home’s level is through professional testing.
The Radon Testing Process
As a Certified Radon Measurement Professional (CNRPP), I use approved long-term radon detectors to provide accurate results in accordance with Health Canada protocols.
✔️ Long-Term Testing (Recommended)
Minimum 91-day test period
Most accurate representation of annual exposure
Detector placed in lowest regularly occupied level
Lab-analyzed results
Written report with interpretation
✔️ Real Estate / Short-Term Testing
Minimum 72-hour closed-house conditions
Used for transaction timelines
Lab-verified results
Fast turnaround reporting
Why Test in the NWT?
Northern construction practices can increase radon accumulation:
Tight building envelopes
Minimal natural ventilation in winter
Crawlspaces common in the region
Long heating seasons
Radon levels vary house to house — even between neighbours.
Testing is the only way to know your home’s level.
What Happens If Levels Are High?
If elevated radon levels are detected:
I will explain the results clearly
Provide mitigation guidance
Refer you to qualified radon mitigation professionals
Help you understand timelines for reduction
Most homes can be successfully mitigated.
When Should You Test?
When purchasing a home
Every 5–10 years as a baseline
After major renovations
After installing new heating systems
If finishing a basement
If you have never tested
