About Us

Radon Solutions is the leading Radon Testing & Mitigation company in Southern Minnesota. We strive to save you both time and money by combining our use of industry knowledge, the highest quality parts and equipment, and our dedication to delivering exceptional service. 

Andrew Kelley, the owner of Radon Solutions of Mankato, developed his interest in radon testing and mitigation while working in the wet basement and foundation repair industry.

His interest in the dangers of radon became a passion when doing a basement job for the director of the Mankato State Radon Project. During their conversations, Andy was shocked to learn of the radon hazards his crew and his family were exposed to. He began an extensive study of the subject leading to the creation of Radon Solutions. Since then, Radon Solutions has performed more than 4000 mitigations and Andy has become a recognized instructor of radon professionals.


He has been a contributor to the development of the Minnesota Radon Awareness Act of 2014 and the Minnesota Radon Licensing  Act of 2019.

Andy is also an instructor for the NRPP (National Radon Proficiency Program) for Radon Measurement & Mitigation Certification. Additionally, He holds a building contractor’s license (BC# 20360055); is certified by NEHA/NRPP (National Environmental Health Agency/ National Radon Proficiency Program); is a member of AARST (The American Association of Radon Scientists and Technologists) and is listed with the MN Dept. of Health.

Andy's son, Mitch Kelley, has been a part of the family business starting at a young age. Mitch received his certification in radon measurement and radon mitigation at the age of 17 and was the youngest certified radon professional in Minnesota. Since then, he has installed over 2000 radon mitigation systems and continues to provide radon services across Southern Minnesota. Mitch, like his father, is licensed through the NRPP and the Minnesota Department of Health (RCI-0006) and is also a member of AARST.

Our team at Radon Solutions consists of highly trained professionals who are passionate about their profession and helping families reduce the risk of radon induced lung cancer. We design every system to accommodate the house's demands as well as satisfying the customers needs.

"Andy is very knowledgeable about radon and patiently answered all our questions. He returned all our calls promptly. After the job was completed, he did a wonderful job of cleaning up. He then followed up on the job to make sure that we were satisfied. We would highly recommend Andy to take care of any radon problems."
