RADON MITIGATION

Madison Radon Testing, LLC is a NRPP-certified, independent radon testing business. We do not sell or install radon mitigation systems.  

When a building’s average radon level is 4.0 pCi/L or higher, the EPA recommends having a radon mitigation system installed. (An average of 4.0 pCi/L is 10 times more radon than is found in outdoor air.)

The most common method used to reduce the amount of radon inside a home is called “sub-slab depressurization”. As you can see in the diagram to the right, a PVC pipe and fan are used to suck up radon that’s located below a home’s foundation and blow it out above the roof line. The wind then carries the radon away from the home.
