    Seth thoroughly inspected all my crawl spaces and didn't hesitate to crawl through holes. I was very impressed. I felt like his radon mitigation plan will get the radon numbers as low as possible.

    Great crew and the install of the Radon Mitigation System was done with care and maintained the esthetic look of the finished basement and garage. I would highly recommend this friendly, honest and professional company.

    Drennen Const. was prompt from the bidding stage to the completion of our new roof project. They kept to their schedule, working from sun up to sundown each day always allowing time at the end of the day for a good cleanup, a great crew all around!
