Radon Testing Services in the Greater Montreal Area

Protect Your Home. Protect Your Family. Breathe Safer.

Radon is a colorless, odorless, radioactive gas that can accumulate inside homes — without any visible warning signs.

At Mose Home Inspection, we provide professional radon testing services to help homeowners, buyers, and sellers understand their indoor air quality and reduce long-term health risks.
With over 20 years of experience and thousands of inspections across Greater Montreal, our certified inspectors ensure accurate testing and clear results you can trust.

Why Radon Testing Matters

Radon is the second leading cause of lung cancer after smoking and is responsible for thousands of preventable deaths each year in Canada.

It enters homes through:

  • Foundation cracks
  • Floor drains
  • Sump pits
  • Construction joints
  • Utility penetrations

Because radon is invisible and odorless, testing is the only way to know if your home is affected.

Is Your Home at Risk?

Radon can be present in:

✔️ New and old homes

✔️ Condos and townhouses

✔️ Homes with finished basements

✔️ Homes with crawlspaces

✔️ Properties across Quebec

Even neighboring homes can have very different radon levels.

📍 Location alone does not determine risk—only testing does.
