Radon mitigation systems are the most successful method to reduce high radon levels in your home. There are a number of radon mitigation system types, and your radon mitigation contractor will review these products with you to determine which one is best for you. Essentially, radon mitigation systems use pipes and fans to absorb high radon levels and expel them to the outdoors. Some radon mitigation systems remove radon before it enters the home, while others may work to mitigate radon that is already inside. The type of home, levels of radon present, and other factors will make a difference in this decision.
