Bill and his team are truly amazing ! Bill is a man of his word , an honest guy , so nice, and just an overall pleasure to deal with. He’s completed plumbing , replaced a hot water heater , and more work on my house I bought just about two years ago. We then decided to convert from oil to gas since the town was running it on our street. He came and gave me very competitive quotes , I had a comfort level of dealing with him, and his team, so I decided to move forward. The town gave us a date the gas would be complete so I paid for the project in full. The town then fell behind on the project and it took well over six months for them to actually run the gas on our street. Bill kept calling to check in one me see if I needed anything and was eager to get the work completed that was paid for, but we were stuck due to the town. Finally about six months later the gas was FINALLY run and he came immediately to start the work. We are so happy with our conversion we now also have central air. We purchased an 80% efficient furnace the company shipped a 90% in error he installed it and ate the difference !! I don’t know a plumbing company in the world that would do that out of the pure kindness of his heart he cares that much about his customers and didn’t want me waiting for my install and stuck to the date he scheduled to be here . He didn’t want me to wait for my install due to a small glitch. I wouldn’t use another company even if the service was free I trust Bill and his team that much ! Stop scrolling for plumbers you found the company you need you will not be disappointed !

Our sump pump was making a beeping noise and we disconnected it. Moe S. was the technician that came and he was outstanding. The sound was coming from the battery backup and he quickly diagnosed the problem and remedied it. He also checked out every part of the sump pump and made sure that it was in good working order! I will definitely use this company for all future planning needs!

Was successful. However disappointed he charge for having to return a few weeks after the first time it clogged. It seemed to be clogged far and I think the issue was never salved the first time and had no warranty for the previous work for same exact clog in same exact situation

Not only did they come on out and fix the leak but they were able to identify some other potential issues with the original plumbing and came up with a solution that allowed me to put everything back together without worries. Also, they even came out and installed a temporary sink for me while my counter and cabinet and sink were removed.

Diamond has always done outstanding work in a timely matter and also left the job site spotless. As a Realtor, many of my past clients will call looking for a plumber and Bill Diamond is the only number I recommend. I can count on his company to take great care of my friends and past clients.
