I had no idea radon could be such a big risk until I tested my home. Radon Ready made the entire process stress-free. The technician arrived on time, explained everything clearly, and set up the test quickly. The report came back fast, and when levels were higher than expected, they provided a step-by-step plan for mitigation. I feel so much safer knowing my kids are protected.

As a homeowner, I wanted peace of mind. Radon Ready was recommended to me by a neighbour, and I couldn’t be happier. The team was professional, respectful of my home, and very knowledgeable about radon exposure. They didn’t just sell me a service – they educated me on how radon affects indoor air quality. I’ve already recommended them to my coworkers.

FAQ

Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil and rock. It’s invisible, odorless, and tasteless — the only way to know if it’s in your home is through testing.

Radon is the #1 cause of lung cancer among non-smokers. Long-term exposure to elevated radon levels can pose serious health risks. Health Canada recommends testing all homes for radon.

Radon seeps into your home through cracks in the foundation, gaps around pipes, sump pits, and even through the concrete itself. Once inside, it can accumulate to high levels.

  • Short-term tests (2–7 days) give a quick snapshot of radon levels, often used for real estate transactions or initial screening.
  • Long-term tests (90 days to 1 year) provide a more accurate average of your home’s radon exposure over time.

We will never recommend mitigation based off just a short-term test.

While DIY kits are available, hiring a certified professional like Radon Ready ensures the test is done correctly and the results are interpreted properly. We follow strict protocols to deliver reliable results.
