John Mattox at Clarity provides thorough, professional, quality service. He did our new home inspection and provided a very detailed report. During the process of purchasing our home, we discovered that radon mitigation was needed. He came in and installed the fan and system to take care of it (in the middle of a snowstorm, no less!) and when we found out that there was a crack in the basement floor that wasn't allowing for a solid seal, he came back and sealed the area. The radon is now much below recommended levels and we can feel safe and secure in our new house. Would definitely recommend him!
