Radon Mitigation systems

Home Inspector with Pillar To Post Home Inspection

I just tested a home for radon which has a mitigation system in place for 15 years. The results were high for 46 out of the 48 hours. The EPA recommends you test every two years if you have a mitigation system in place. There is a reason for this. Conditions change. You may have new cracks in your foundation walls or floor. Other situations may occur after the system was installed. the system itself may not be functioning correctly. In any case when you write a offer on a property that has a radon mitigation system do not tell your client they do not need to test unless you have test results that are within two years or you may find yourself sitting in court. Radon is serious it is the 2nd leading cause of lung cancer behind smoking and ahead of asbestos.

Just like any other mechanical device, radon mitigation fans wear out over time. The average life span of a radon mitigation fan is around 10 years. It is no surprise that a 15-year-old fan (like the one you reference) is no longer effective.

A modern, properly installed radon mitigation system should have an indicator that the homeowner can look at to see if the fan is creating the proper suction. When the fan no longer creates the needed suction it is time for a new fan.
