I discovered a leak under my water heater at about 9am on a Sunday. I called Mr. Rooter and within an hour they were at my home. The two plumbers were extremely courteous, knowledge and totally transparent. Luckily it turned out it wasn't a major issue and they had the leak fixed and the water cleaned up within 30 minutes. I would not hesitate to use Mr. Rooter again. They are now my first choice for any plumbing issues.
