When we heard our water heater had to be replaced and had no hot water, we were very concerned. Since our heater was so old and the work done to it was over 15 years ago, the work around it was no longer at code. We not only required a chimney liner but also tear out before our new water heater could be installed. I called John Townshend on an emergency call and right away I had a return call and same day service for estimate and repairs to begin. This was so important to us because we have a 1 year old in the house. The workers were polite, professional and did a wonderful job. It was done in a timely fashion and there was no mess which made it a pleasant experience!
