What to know about Radon testing & mitigation
Radon testing and mitigation means measuring the level of radon gas in a home and, when it's too high, installing a system that keeps it out. Radon is a radioactive gas that forms when uranium breaks down in soil and rock. Health Canada describes it as invisible, odourless and tasteless; it seeps into houses through the foundation and can build up indoors.

How to choose radon specialists in Le Plateau-Mont-Royal
- Choose a contractor who finds the source of the water before recommending a fix, whether that's grading, eavestroughs, cracks or drainage.
- Ask them to explain the difference between interior and exterior waterproofing for your home, and why they recommend one.
- For foundation cracks that are wide, growing or uneven, ask whether a structural engineer should assess them first.
- For mould, asbestos or radon, hire professionals qualified for that specific work, and don't disturb suspect materials yourself.
- Get a written quote that lists excavation, membranes, weeping tile, sump pumps and restoration of landscaping or finishes.
Questions to ask radon specialists before you hire
- Where do you think the water is coming from, and how did you confirm it?
- Do you recommend interior or exterior waterproofing for my home, and why?
- Should a structural engineer look at these cracks or this wall?
- Does this work need a permit from my municipality?
- Is your warranty transferable if I sell the house, and what does it cover?
- How will you restore the landscaping, driveway or basement finishes afterwards?
- If you find mould or asbestos, how will it be handled and by whom?
