Radon mitigation solutions in Illinois

Most home issues are obvious, and as a homeowner, you're usually aware of the problem soon after it arises. After all, when your Illinois home has a structural issue or needs a new paint job or remodeling, the signs are clear and the benefits are obvious. But you won't see any signs when your home is harboring dangerous levels of radon gas.

That's what makes radon gas so hazardous - your home could have dangerously high radon levels, and you would never know without conducting a radon test. Radon is tasteless, colorless, and odorless, and because of these characteristics it's impossible to tell if your home is at risk. There could be a gas within your IL home that is proven to be the second leading cause of lung cancer in the U.S.

Authorized, highly trained radon contractors from National Radon Defense want to inspect your home to identify the radon levels and provide radon mitigation services to maintain a healthy radon level within your home.

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.
