Frequently Asked Questions


My home does not have a basement, do I still need to test?

Yes. All home types should test for radon.  This includes condos, town homes, homes with crawl spaces, homes on a slab, manufactured and modular homes, and apartments.


Will granite counter tops increase the radon in my home?

Probably not.  At this time, the EPA does not believe sufficient data exists to conclude that the types of granite commonly used in countertops are significantly increasing indoor radon levels.

How does radon enter my home?

Radon is a gas, radioactive particles, that are drawn into your home through a number of pathways. Buildings are like vacuums, drawing gasses of all sorts inside. As radon is naturally made under your home, then the suction of the building draws radon inside.


May I install my own mitigation system?

Yes. There are no laws preventing you from installing your own radon mitigation system. Make yourself aware of any local ordinances or building permit requirements. Your local government may require a building permit. Electrical work may require a licensed electrician. You may also want to also consult with any other governing body such as a home owner’s association.


I have a radon mitigation system in my home. Can I assume my radon level is low?

No. Some North Carolina homes have radon mitigation systems that were installed in the 1990s. Radon mitigation fans are generally warrantied for 5 years. The recommendation is to test your home at most every five years, whether or not you have a radon mitigation system. This will help you determine if your system is keeping indoor radon levels low.
