Radon is a radioactive gas that occurs naturally in soil. As radon rises from the ground, it can enter a home and build to dangerous levels. If you have a well, it can also make its way into a home’s drinking water and plumbing.

Exposure to radon can cause serious health problems. In fact, radon gas is second only to smoking as the leading cause of lung cancer [1]. 

Radon is invisible and odorless. So, how can you know if it’s there? Get a radon test.

Radon Testing FAQs

Still have questions? Check below to see if we’ve answered them. If not, check out our FAQ page or reach out to us.

How long does a radon inspection take?
Testing can take anywhere between 48-96 hours. We will deliver the report to you within 24 hours from when we pick up our equipment from the property.
How do I need to prepare my property for the test?
In order to perform a radon test accurately, the windows and doors in the home must be completely closed for 12 hours before and during the test. If this is not followed, you can get inaccurate results and the test will need to be repeated.
Can you test for radon in a condo property?

Maybe. If the condo is a townhouse-style property, and there is no shared open space in the basement or attic, then we can test for radon.

However, if the condo is an apartment-style unit, we cannot test for radon. This is because the conditions for radon testing require windows and doors to be closed before and during the radon test. We can’t control what other units do with their windows, so we can’t promise a successful test in this specific case.

Contact us for more information on testing your condo for radon.

Can you test for radon during the summer?

Not if it is hot outside and there is no air conditioning. Because radon inspection and testing requires you to keep the windows and doors closed for a period of 12 hours or more, this can create uncomfortable and even dangerous temperatures inside the home. Speak with one of our associates to learn more about your specific situation.

Can radon infiltrate my drinking water or my plumbing?
Yes to both. If your home is on a private well, you may have radon seeping into the water coming into your home. Radon in water is often an issue in the bathroom, shower, and/or other areas where water is aerated.
Can radon in water be mitigated?
Yes. There are mitigation systems for radon in well water. If your well is found to have an elevated level of radon, you need to consult with a water conditioning specialist to find our your next steps.
