"Based on Angie's List reviews, I contacted The Clean Plumbers and scheduled a service call. The plumber showed up as scheduled and even called to let us know he was enroute. He diagnosed the problem and replaced both the upper and lower thermostats. He also noticed that the water heater circuit breaker was functioning intermittently and replaced it. He completed the work neatly and professionally, and the water heater was restored to full function."

"Happy with their installation of an add-on electrical box, so we could get our new electric tankless water heater up and running after Hurricane Irma wrecked our old tank water heater. Very happy with our continuous hot water."
