About Us

About Harner Radon Relief

Let's clear the air throughout Northeast Ohio!

Harner Radon Relief started because we noticed many homeowners throughout the Northeast Ohio community lacked knowledge about the dangers of radon. We saw an opportunity to help spread awareness and improve people's lives with something as simple as radon testing and radon mitigation services. Radon is an odorless and colorless gas, making it virtually undetectable without proper equipment, and research has shown it is a leading cause of lung cancer after being consistently inhaled. With cancer having affected the lives of both our owner and manager closely, we want to help the people of Northeast Ohio protect their families in any way possible. Your family could be facing major health issues from a threat you might not even know existed in your home. Keep your family and radon out of your home with help from Harner Radon Relief.

Why Choose Us?

We operate under the combined perspectives that value knowledge created by decades of experience alongside a love of technology that pushes for innovation. Our team specializes in radon testing and mitigation, mold inspections and testing, and a range of indoor air quality services, so you can rest assured that you are always protected. As members of the National Radon Defense network, Harner Radon Relief has access to exclusive products to protect your home from radon gas and training courses to keep our contractors knowledgeable and at the top of their game. Schedule your radon testing, mold inspection, or free estimate today. We proudly serve homeowners in Cleveland, Akron, Mantua, and surrounding cities.
