I do not give review a lot but after using another company to do my first radon mitigation system, Lawrenceville GA in November, 2025, I was very disappointed. The first radon system was expensive and my radon level became high again. Simple, the radon system was not working well. The company [ASE] who did my radon mitigation was lacking in experience and just wanted more money for another radon mitigation suction point. I got frustrated and reached out to Georgia Radon Defense, GRD. GRD, came out and diagnosed the major problem with ASE radon mitigation system and they fixed it immediately. They charge me less than ASE would charge for another suction point, that would not work. GRD was professional and they explained every detail of their work. I felt very comfortable with their work and knowledge. They fixed the problem. Now my radon level range from 0.9-1.5. This is the best company I would recommend for your family and your health. read more

Horrible service. We booked radon mitigation on July 8th. Trent installed a tap in the front room of the house and we thought it was done. When he left he told us that he wasn't getting good communication, so none of the radon was being let out of the home. He gave us a free test to check the levels and I got the test back and our levels were at 5.4. So I tried calling for two days to get someone to come out and nobody would call back. I finally emailed the owner of the company and he said that no one could come back out until August 3rd. My husband and I are scheduled to move in our home July 25th. So not only did Trent not communicate that we needed two taps, but he installed the taps in the wrong part of the house. Oh and the icing on the cake is that Trent quit and didn't take sufficient notes and no one in the company knows what to do. Trent didn't tell us that we needed an additional tap but he put that information in the notes. So now I will need two more taps installed into my home and my husband and I can't move in. We also are being charged for an additional tap. Honestly we are going to go with another company because not only is the business owner not accountable for the mistakes that his installers make, he didn't even feel remorseful. Trying to say that our levels are livable....waste of money and time. So now we get to pay another company to get the job done correctly. read more
