Stay informed about radon exposure in Missouri

There's a reason that Missouri is known as the "Show Me State" - its residents are known for being skeptical and seeking out proof before accepting belief. As a homeowner, you have a right to be informed about the health and condition of your home. Unfortunately, when it comes to radon gas, it's not so simple to find visible proof because radon is invisible, odorless, and tasteless.

The good news? The presence of radon gas in your MO home can be discovered with a radon test. Highly trained radon contractors from National Radon Defense can determine whether your home has high radon levels and install a cutting-edge radon mitigation system if necessary.

Reliable radon testing and radon mitigation services

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 radon levels but also provide solutions for maintaining healthy indoor air in your Missouri home. You deserve to get the facts so that you can take necessary action to protect yourself and your family from the dangers of radon exposure.

We Provide:
  • Radon testing
  • Radon mitigation systems
  • Multi-family radon testing & mitigation
  • Vapor intrusion mitigation
  • Indoor air quality services
 You Receive:
  • A healthy home environment
  • Clean indoor air
  • Protection for you and your family
  • 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.
