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

The most amazing experience with Brad!  Explained thoroughly every step of the process to me and did an impeccable installation.  I was amazed at the precision the drilled holes were in my stucco home!  My radon levels in the basement dropped almost immediately!  Recommending Great River Radon to everyone!  :-)

Experienced professional who takes pride in his work.  Not only did Brad setup a radon abatement system that we're very please with he also saved our basement from flooding.  When Brad was doing the work of installing the radon abatement system, he noticed that our sump pump was acting up so he offered to order and install a new one.  The day after the pump arrived we had a spring torrential downpour.  Luckily Brad had the part in hand and came to our house to install the sump pump - under water no less.  My guess is we had maybe a half-hour before the water would have started to pour into our basement.  What a guy!

Alyssa arrived on time to place the radon tracking equipment in my basement.  She was pleasant and professional.  A week later she came back to let me know my radon levels were safe. So relieved. She was honest, timely and a pleasure to work with.

Amazing! When I bought my home, a radon system had been installed. But when we re-tested the radon levels, it wasn't working that well. Brad installed an extension that brought our levels way down! Thank you!!

Brad was great to work with, responded quickly and got our radon inspection done in a tight timeframe. We were able to get the result of the test the moment it was done. Brad is very knowledgeable and taught us a lot about homes in Minnesota. He spent time with us, answering all our questions.

I would hands down recommend Great River Radon. Brad is professional and very knowledgeable. I have used him for two different houses and each time everything went smoothly.

I would highly recommend this company for your radon mitigation needs.  Brad was incredibly knowledgeable, efficient, and helpful.  He truly is the Radon Man!
