How Does a Mitigation System Work? 

A radon mitigation system draws radon away from your home, and vents it harmlessly into the atmosphere to prevent radon emanating from the ground from getting into the house. We do this by reaching down under the house with a pvc pipe (a “suction point”), running the pipe up and out of the house until it ends above the roof. A radon fan in this system creates a vacuum field under the house, pulling the radon gas, as well as other gases and moisture, out from under the house and venting it above the roof.
 

Concrete floor or dirt/crawl space?

How radon enters a house

We install either an Active Soil Depressurization (ASD) System or Sub-Membrane Depressurization (SMD) System. Both of these work the same way. In the first, we can go under the basement floor (slab). In the second, we install a radon-resistant membrane over a dirt floor or crawlspace. Sometimes a system uses a combination of the two methods. 

Heat Recover Ventilator (HRV) – Occasionally, the diagnostic evaluation will indicate that a building requires a heat recovery ventilator to reduce the radon levels. Also called an air-to-air heat exchanger, it is installed to increase ventilation, thereby reducing radon levels. A high performance HRV can provide comfortable, continuous, balanced ventilation for the entire home. 

NOTE: Once a system is installed, it must run all the time. The radon fan is very quiet and efficient, and costs about as much as a light bulb to run. Turning the system off and on will shorten the life of the fan, which has a 5-year manufacturer’s warranty.
