Great River Radon, LLC

My wife and I bought a new house with high radon levels. Brad and Great River Radon were referred to me as someone who not only would do a great job, but would go the extra mile to ensure we were in a good place going forward. Our radon levels beforehand were above 11pci/L in our basement and above 5 in our living room. He got it down to 0.4pci/L (the same as outside) in the basement. He replaced our sump pump, was very flexible, and accommodating with the installation etc. We couldn’t recommend them more!

Like another reviewer I made the mistake of hiring Brad to test my house. I paid $175 for the test knowing the price would be deducted from the mitigation bill. He picked up the testing equipment which showed a high level. Well It's been a year and a half and after several emails and at least twice speaking to him with the promise of a quote each time I have never received anything. I also asked for a refund but was ignored. Brad if you would like to make this good please do.

Called about an issue with existing system that this company did NOT install. Gave me (free) advice over the phone on something to try first, and to call them back if it didn't resolve it. Impressive!

From the beginning of the initial estimate to the final radon test, working with Brad and Alyssa at Great River Radon has been a positive experience. They were very thorough in their explanation of how Brad would approach the radon mitigation for our house. Brad was conscientious and meticulous in labeling the system and educating us on how it worked. He said he would be happy to test every other year to make sure our radon levels stay at a safe level. Initially our radon level was at 6.7. After installing the abatement system our radon level is now at 0.8. Brad also alerted us to a problem in our basement and offered solutions on how to solve it. We would highly recommend Great River Radon.

Brad was friendly and provided a great service. Our radon mitigation system brought our radon levels from dangerous levels of 6-8 to below 1. He was fast and competent. Highly recommend.
