Jim was absolutely the nicest most professional technician. He explained everything that he was doing and when the reports came back he sat down and explained everything in the report. Stephanie in the office was kind and very professional. She was very responsive and answered all my questions. I will definitely use them again when I need another radon test. I’m very happy with the services I received.

Jim was so very helpful. He described what he was looking for and what the standard of the air should be.They took care the installation and cleanup. Came back to make sure everything was working as it should be. We could not be more satisfied.I would recommend Reliable Radon to anyone needing their basement check out!

Reliable Radon Inspections completed our radon for the house we bought. They were very responsive and communicative and scheduling was very easy. They were able to get in to complete the inspection within our tight window and were flexible when they realized our house required more systems than initially expected. I would definitely recommend using Reliable Radon Inspections for your home.
