For the first time, I just tried Mechanical Man, Inc. I gave them a call and they were quick to respond. My son stayed with the technician when he came out and he said that everything went very well and the tech was professional and very nice. They wound up having to replace the sewage injector in the basement. Everything turned out fine and he did a really good job. Mechanical Man, Inc. offers extremely good service and quality workmanship, so you really get what you pay for. I would definitely recommend them to others and I would call them again myself. It was a very pleasant experience overall.
