We have worked with Capital Plumbing & Heating for about four or five years now. Most recently they helped us with an issue of water knocking. The washing machine is now working better and smoothly. There were still vibrations felt in the upstairs bathroom when running the dishwasher. So they tested it but said it was from a different problem. They also noticed that the water tank went off and said something about a gas valve needed to be repaired. We are still working on getting everything set, but Capital has always helped us out. Even when our heater went out in the middle of the night one winter. They are responsive to our calls and we would recommend them.
