Comments: They were on time when promised. The work was done fairly quickly (about 3-4 hrs) and they left no mess. Most importantly, the work done has solved the radon problem, lowering numbers from 15-25 down to less than 1.

Comments: Andy from Tristate was a real professional. He was prompt, knowledgeable and the entire analysis was completed on time with an easy to understand report. We will use this company every 2 years to monitor radon. We could not be more pleased with Andy and Home Builder! John Seifert

Comments: They went above and beyond to make sure I agreed with the placement of the unit. They even fixed an electrical outlet that was wired incorrectly.

Review Date: 12/18/2018 | Author: Joann E.

Comments: I was extremely impressed with the professionalism of both workmen. They listened to my concerns and we were able to come up with an alternative approach to placement of the system. They were able to provide protection of both areas of my home with one system instead of installing two separate Radon systems. The system was placed in the unfinished area of the basement leaving all my finished area untouched. They left the work space cleaner then it was when they started and made sure everything was put back in place. I highly recommend Tri State Radon and Mold, Inc.

Review Date: 03/23/2016 | Author: Don G.

Comments: They were very honest, experienced, fast and specific as to what would be done and the results were excellent as promised. The location of the pump was perfect and out of the way and the fan size eliminated any additional hole requirements. They cleaned the area when done and the workmanship was professional and high quality and the price beat everyone else. I wouldn't look anywhere else if you're in need of Radon mitigation.
