A radon mitigation system is designed to be a permanent part of your home. However, just like other home mechanical systems, it needs to be regularly maintained. Guardian provides maintenance, inspection, and diagnostics on your current system. Our experienced field technicians are licensed by the Illinois Emergency Management Agency (IEMA) and qualified to complete all mitigation service repairs.

Chris, Mary Ann, Tyler and the whole team were wonderful.
Very professional, knowledgeable kind and thorough with the radon mitigation process. They worked with us diligently and the installation of the system was super quick and easy. They answered all our questions and provided us with very useful information for the future. They are very used to the process of radon mitigation for a real state transaction so they also provided all the parties with the paperwork needed, avoiding delays or last minute hurdles. I would definitely recommend it to anyone looking to install a mitigation radon system.
