"We had our radon fan replaced by Radon Bros in January 2025. From the beginning, the new fan was noticeably louder than the previous one. At that time, the technician advised us that the increased noise was due to the fan being stronger than our prior unit. Over time, the fan became increasingly louder and ultimately stopped working in early December 2025. When a technician returned to replace the fan, we were informed that the fan originally installed was defective and that Radon Bros had stopped using that manufacturer due to known issues. Despite this, we were charged a $99 labor fee for the replacement. We do not understand why we were responsible for this charge when the failure was due to a defective fan that your company was already aware of and no longer installs. We felt we had no choice but to pay the $99 in order to have our radon mitigation system restored and functioning properly."

"Work and overall communication was excellent"

"Our project was completed with Complete professionalism by Tony and his project manager, Christian.
