The Supervisor, was much more knowledgeable and explained everything that had stumped the younger worker. Of course he was working on a 50 year old mobile home. The supervisor was quick to explain to us and to the worker what was needed and how to fix it. They were both very polite, communicative, detailed in explanation and considerate of all of us. I would recommend this company to my friends and co-workers. They called to let me know when they would be there and gave me an accurate account of what it would cost before I ok'd them to fix it.
