"The provider came out to prepare my toilet because it was leaking in the basement. Overall, I thought the process went well. He could not get the valve beside the toilet to turn off so he turned off my main water valve to the house. He only opened up the faucet upstairs unit Downstairs unit was not open and my water heater, which is electric was not turned off now I m getting an alarm on my water heater saying it has been compromise. I consulted a plumber and was told that the water heater should ve been turned off because it s electric and he should ve bled the water heater After he turned the water back on. So the alarm is still on my water heater."

In 2008, Landry Mechanical Inc Plumbing HVAC & Electric began serving residents throughout Worcester and Middlesex County. We started out just serving 20 systems a year and working on systems that our competitors ignored, such as wood systems or alternative energy systems. In putting our customers first, our reputation for quality work grew, as did our business.
