Our house had a medium level of radon (peaking at 12) in the basement. As we wanted to minimize our exposure and make the basement less hazardous, while increasing resale value, we had American Radon install a mitigation system. We have a standard cicra 1980 non-waste sump pit without pump, so we had them install a sump pump at the same time. The installation was done professionally over the course of a single day. Results: down to a ~1! Highly recommended for Radon Mitigation!
