GAP Plumbing came out to replace a water heater at a rental property of mine. Everything went well from start to finish. This was the first time I used their services. I found them on the internet. When I called the office their staff was pleasant and they were able to schedule the appointment during a time frame that fit both me and the renters. The technician was prompt, polite and professional. He was knowledgeable about the unit and explained what he was doing and took the time to answer our questions. I would recommend using GAP Plumbing!
