6/30/25: Cook's did a 48 hour radon test with their calibrated Sun Nuclear model 1028 radon tester. They tested in the center of our unfinished basement. Unfortunately I have high radon (8.3) in the basement. Cooks will be doing the mitigation...because I trust Tony Cook (owner) who provided the best and most detailed quote for mitigation...and seemed to me to be the most knowledgeable. 7/17/25: Eli & partner from Cook's did the radon mitigation. They were on time, cleaned up after themselves and did a nice job. See the pics. They are doing another radon test now to see how much their mitigation efforts lowered the numbers. Results: 6/30/25 - 7/2/25 (48 hours): Pre-Mitigation testing done by Cooks: 8.3 7/18/25 - 7/20/25 (48 hours): Post-Mitigation testing done by Cooks: 2.0 My Airthings Corentium Home Tester showed 8.48 pre-mitigation and 2.13 post-mitigation. Similar results. Cook's quote was right on target. Final bill was the same #. Exterior venting of fan is a bit noisy...but can only be heard from the driveway. They have a muffler option that I may use in the future, but the venting noise is not heard in the house or garage. I'd highly recommend Cook's Radon.

While we are waiting to check our radon levels after work was done I can share that Eli, who did our work, was fantastic. Kind, knowledgable and a great communicator.
