I had GAP Plumbing come out to do some work at my house, then again at my parent's house. I located them after searching for a plumbing company online, and I called them up because of a broken water heater. I had no problems with their office staff, and within a day they had come out to see the problem. There were some issues with doing a straight water heater replacement, so we ended up getting a tankless water heater installed. I was very pleased with their work and their professionalism. So much so, that I called them to go do some work with my parents. They took care of some leaky faucets and did a good job. Thanks to my new tankless water heater, I'll have them over regularly for routine maintenance and anything else I may need.
