If you feel the radon levels are high enough to justify installing a radon mitigation system, we recommend installing a good quality, durable, energy efficient system. The EPA recommends that you have a system installed in your home to reduce the levels below 4 pCi/L. Certified mitigation contractors will assess the source of the radon and use the best method to lower these levels. Lowering radon gas levels in your home to a safe levels requires specific technical knowledge and proper equipment. Unqualified homeowners trying to install systems could actually cause an increase in radon levels in their homes.
