If your radon levels are above 4.0 you will need a mitigation system put in.
Radon mitigation is a process used to reduce radon gas concentration in the breathing zones of occupied buildings, or radon from water source.
Radon removal system draws the radon gas from beneath the foundation of the home to be directly vented outside without having a chance to enter the home.
The installation process takes a few hours.
According to the EPA, radon removal can eliminate up to 99% of radon from the home.
