"Jeff installed our radon system in a very timely manner and coordinated with real estate agents to get system installed before our closing. He answers emails and texts right away. I would not hesitate to use Buckeye Elite-highly recommend."

"MaGen did an amazing job testing and abating our radon issue, which we weren't even aware of. Maryan's process was easy to follow, he performed work that was even beyond the agreed process (like making necessary fixes to our crawl space), and ensured that the radon system was working well. We went from having the meter read over 10 (pre-work) to under 1. If you're looking for someone that can handle your radon needs, get MaGen to do it ASAP!"

"Absolutely professional. Tyler came out exactly on time. His co worker/partner set everything up and explained the process and worked with our schedule. Pricing was VERY affordable and for a job done exceptionally well and clean. I reccomend getting the levels tested in your basement as over time this can be detrimental to ones health. If we have any issues in the future, I will be using Ohio Radon Specialists for all of our mitigation needs."
