"I highly recommend A1 for radon mitigation! They did an excellent job and I was very satisfied with both the installation and the results. Andrew was very professional, knowledgeable, and extremely responsive in his communication. Andrew and Rob installed a drain tile depressurization system, which was vented thru the attached garage roof. The fan was located in the garage attic, which required electrical work by their sub-contractor Brothers Electric. The installation took about 2 hours, whereas the electrical work was completed the next day in about an hour. A1 provided a short-term radon test for post-mitigation testing. My basement radon level went from 4.7 to 0.6 pCi/L."
