I had done several radon measurements since we occupied our new construction home and was seeing radon levels of between 2.0-4.0 pCi/L and I decided I would like to have the problem resolved. I did my usual Google searches and came upon Benner GeoTech and I must say on the first phone call to Mike, I was immediately impressed with his level of professionalism and questions being asked to estimate and schedule the job. We had a few back and forth phone calls in order to get my date scheduled since he is always quite busy doing remediations, but it was worth the few week wait time for Mike. I had also contacted others concerning their mitigation servers, but was not impressed with their manner on the phone nor price. MIke called me the night before in order to get my address location and to be sure he was going to be driving to the right place. He arrived promptly around 8:15am and started his work right away asking to see the basement and upstairs areas that he would need access to. Throughout my experience with Mike he was always listening to my questions/concerns and was always eager to educate on the topic of radon and how these systems work. Mike always removed his shoes and made sure to put down a new blanket to catch any insulation from the attic hatch space. He was able to quickly install the radon removal fan in the attic space, wire it up, and install the necessary fan monitoring in the basement pipe in a little over 1hr. This was quick due to the fact the house already had a passive pipe installed into the sump area from the builder. A test kit with fully paid for shipping was included to verify the mitigation system was working after a couple of days. I have my own digital tester and after 48hrs (*hard reset) the levels went from 3.7 down to 0.5 pCi/L! This is amazing since Mike promises a 2.0 or less for his work, so this has exceeded my expectations for radon reduction. *The test Mike provided also came back with a 0.8 pCi/L. Very small fluctuations have been seen in the basement since the system has been installed, but it still remains less than 1.0. Mike's experience with doing radon mitigations shows and I would highly recommend hiring him to get the job done right the first time. He is an expert in his field and is very nice to work with.
