A local statistic cannot tell you what is in your home.
The regional study confirms that elevated radon exists in our area. But levels can differ greatly between neighbouring houses. The only way to know your home’s level is to test it properly.
- New and older homes can both have radon.
- A neighbour’s result cannot predict yours.
- Long-term testing gives a more useful average.
The essential idea
Radon is invisible. The decision process does not have to be.
Radon is a naturally occurring radioactive gas from soil and rock. It can enter through foundation openings and accumulate indoors. Because it has no colour, smell or taste, testing is the only way to estimate the level in a home.
Learn how to test properlyMeasure
Test for at least 91 days on the lowest normally occupied level.
Understand
Use the full-period average and compare it with 200 Bq/m³.
Reduce
If the long-term result is elevated, explore a professionally designed system.
Verify
Test after mitigation and re-test periodically to confirm performance.
Understanding a valid long-term result
Use the number to guide a plan—not a panic response.
The Canadian guideline is 200 Bq/m³. Test length and placement matter, so confirm the measurement before deciding what the number means.
Below Canada’s guideline. Check whether enough of the test occurred during the heating season.
Health Canada recommends reducing a valid long-term result in this range within two years.
Current guidance recommends reducing the level within one year. Plan a timely assessment.
What mitigation does
Intercept radon before it enters the living space.
The most common approach is active sub-slab depressurization. A pipe and small fan draw soil gas from beneath the foundation and discharge it outdoors. The home’s foundation determines the final design.

Diagnose
Assess slabs, crawlspaces, entry routes and pressure.
Install
Place suction points, piping, fan and safe discharge.
Confirm
Use post-mitigation testing to verify performance.
What may affect cost
No honest quote starts with the number alone.
Health Canada currently gives a typical Canadian range of $2,000–$4,000. Your foundation, access, crawlspaces, routing, electrical needs and system design determine the actual estimate.

Check the qualification—do not assume it.
