What is radon mitigation and how does it work?

Radon mitigation reduces radon levels by redirecting radon gas from beneath or around a property to the outdoors before it can accumulate inside. South Dakota Radon Defense designs and installs customized radon mitigation systems based on your property's construction, radon test results, and specific needs.

Our radon mitigation services include:

  • Customized System Design
  • Residential Radon Mitigation
  • Commercial Radon Mitigation

Why should I have my home tested for radon?

Radon is a naturally occurring radioactive gas that enters properties through the ground and accumulates indoors. Because radon is invisible and odorless, it cannot be detected without proper testing. It is also one of the leading causes of lung cancer in the United States, making radon testing an important step in protecting your indoor air quality. 

Whether you're testing an existing home, commercial property, or newly constructed building, our team can help you understand your radon testing needs. Contact South Dakota Radon Defense to schedule a free estimate and take the first step toward addressing radon concerns in your property.
