We used CME for, what I will call, a major issue in our warehouse/shop restroom sewer drains. A 60 year building will do that to you. CME came in on their scheduled date and went to town. I now know why this was such an expensive fix. They had a crew of 3-5 guys for almost two full days and they worked their butts off. Between the heat, sweat and fragrant smells, along with truck loads of expensive equipment, the job was completed in a timely and professional manner. We had a very concerned and considerate crew that took care of any questions and showed us a few things along the way. It's nice to see that the guys take pride in the work that they are performing. Hopefully, I never need to use them again (lol), but I will not hesitate to call CME again if any sort of issue like this comes up in the future. Great company.
