SC radon testing and radon abatement services

Every South Carolina homeowner should seek the help of the radon experts at National Radon Defense. Radon can seep into your home from the soil and rocks below, and it can only be detected through a radon test.

Smoking is known to be the leading cause of lung cancer, but radon is a close second. In fact, radon exposure is responsible for approximately 21,000 deaths per year.

Allow for the professionals at National Radon Defense to detect your home's radon levels and bring them down to a healthy level.

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.

    I had True Air Technologies run a test on my house and was very please to see that the radon in my house was very low. The test only took two days and it didn't interrupt any of our normal daily activities, in fact, we didn't even notice the test unit was there. To protect your families health, I would highly recommend have them test you home or business.
