Radon testing & radon removal in Wisconsin

High levels of radon gas are common in Wisconsin homes. This naturally occurring gas causes lung cancer and can leak into your home from the soil and rocks below. The only way to assess whether your home has dangerous levels is by completing a radon test, since radon is impossible to see, smell, or taste.

Although you may not be able to detect it with any of your human senses, the radon professionals at National Radon Defense can not only inspect your home's levels but also provide solutions for maintaining a healthy radon level in your Wisconsin home.

Contact a local National Radon Defense dealer in WI today

You Receive:
  • A healthy home environment

  • Safe radon levels
  • Peace of mind
Although no homeowner wants to increase cancer risks for family members, many people neglect to test their homes for radon, an invisible, odorless, cancer-causing gas that emanates from soil and rocks. Contacting a radon mitigation specialist to perform a radon test, or conducting your own test with a DIY radon test kit is the first step in protecting your family from hazardous levels of radon gas.
