Radon Mitigation Ottawa
Radon is a serious concern across the Ottawa Valley and Outaouais, where uranium-bearing bedrock can release the radioactive gas into homes through foundation cracks. It's the second leading cause of lung cancer — the only way to know your level is to test, and a sub-slab depressurization system is the proven fix. Ottawa's wide temperature swings — from -30°C in January to +30°C in July — and older housing stock in neighborhoods like Westboro, the Glebe, and Orléans make insulation, air sealing, and moisture control high-value upgrades. Exposed bedrock in areas like Kanata and Stittsville also makes radon a real concern.

Radon Mitigation Ottawa — Common Questions
What is radon and why is it dangerous?
Radon is a naturally occurring radioactive gas that forms from the decay of uranium in soil and rock. It seeps into homes through cracks in foundations and is the second leading cause of lung cancer after smoking.
How do I know if my home has radon?
Radon is odourless and invisible — the only way to know is to test. We offer professional radon testing as part of our free home assessment.
What is sub-slab depressurization?
It's the most effective radon mitigation technique. A pipe is inserted through the floor slab and a fan draws radon gas from beneath your home and vents it safely outside before it can enter.
How long does radon mitigation take?
A standard installation takes about one day. Post-installation testing is done to confirm radon levels have been reduced to safe levels.
