About Knox Radon EMT
Central Ohio's Trusted Radon Mitigation Specialists
We started Knox Radon EMT with one goal: give central Ohio homeowners a certified, honest, and dependable option for radon testing and mitigation — no upselling, no shortcuts, just results.
Our Story
Knox Radon EMT was founded in Mount Vernon, Ohio by a team of certified radon professionals who saw a gap in the local market: too many homeowners were either unaware of their radon risk or being overcharged by out-of-area contractors who didn't understand central Ohio's unique geology.
We built this company on the belief that radon mitigation should be straightforward, affordable, and done right the first time. Every job we take on is treated like it's our own home — because we live and work in the same communities we serve.
Today, Knox Radon EMT serves homeowners across Knox, Licking, Delaware, Morrow, and Richland counties. Whether you're buying a home, selling one, or simply want peace of mind, we're here to help.
