There's lots of wonderful and unique characteristics that describe Missouri, almost too many to name. But, one that it shares with every other state is the radon gas presence in most homes.

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 Missouri home.

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.
