I contacted Radon Gas Experts to get a radon mitigation system installed in my home. I was told that I would have to pay $500 for an inspection before they would even consider installing a system, despite my finished basement making it obvious that there was not much to inspect. I reluctantly agreed, and an inspector named Michael came out to "inspect" my home. The result of the inspection was that the radon was coming from under the ground, which I could have told them without spending $500.
The "unique" system they designed for my house was a basic radon mitigation system that could be seen anywhere on the internet. They also emailed me a generic pdf that explained the radon mitigation process (again nothing specific about my house and nothing I couldn't find on YouTube). Michael was confident the system would work, but would not put anything in writing.
I signed the contract that Michael had sent me for the mitigation system and gave them a deposit, but we could not proceed with the installation as the initial installation date on the contract was no longer valid. Michael then sent me another contract with a new installation date. Believing that the only change was the date, I modified the date on the original contract and sent it back to Michael. However, Michael later refused to proceed with the installation unless I paid the full cost of the installation upfront because I had made an "unauthorized modification" to the contract in his words. Upon comparing the two contracts he had sent me, I realized that he had made other changes to the second contract aside from the installation date, which were not disclosed to me. This misunderstanding could have easily been resolved over a phone call, but Michael ignored my requests for a call.
I am glad they refunded my deposit, but it still stands that I paid $500 for a worthless inspection. Overall, my experience with Radon Gas Experts was extremely frustrating and I would not recommend them to anyone.
