A short check after install and a long-term test the next heating season to confirm the result.
A short test a day or two after the fan is running confirms the system is doing its job. Health Canada recommends a long-term three-month test the following fall or winter to confirm the annual average is below 200 Bq/m³, ideally by someone independent of the installer.
We can set up that test, or tell you how to do it yourself with a lab kit.
Retest every few years and after major renovations, such as finishing a basement or replacing the furnace.
Long-term 91-day tests in the heating season, plus short tests for real estate deadlines.
A fan and sealed pipe that draw radon from under the slab and vent it outside, installed in about a day.
Airtight sump lids, sealed floor cracks and membrane over dirt crawlspaces.
