Arlington Radon repairs mitigation systems. The radon mitigation fan life is typically 10 years, when it stops working higher levels of radon will enter your home. A clogged radon vent can also prevent radon gas from exiting your home. It is important to make sure your system is functioning properly for the safety of those in your home. For most systems we use Radonaway fans which come with a five year from date of manufacture warranty.
