Bill came prior to the job in order to create exit piping due to our new siding job that was in process- much appreciated! He spent quite a bit of time explaining the systems we might choose and answering our questions. Very professional and a pleasure to work with. Everything was immaculate when he finished the job. Highly recommend!"

"Our heater stopped working around 7 pm during the night, last Feb 2026. We had no heat for the whole night so it was really cold inside the house the next day. To our relief, Mark was able to come out the very next day in the morning. Mark checked and tested numerous devices on the furnace. He explained everything that he was doing while repairing the furnace. He was here for only an hour and got our heat going again. He's friendly and trustworthy. He is our Plumber and we call him for any problem. His rates are reasonable. We highly recommend him. We live in Brockton 02301."

"Had mike and zach out to replace my gas water heater. They were on time, professional, and courteous of my home. They even wear shoe covers and use drop mats to make sure the floors dont get dirty! Excellent customer service at a reasonable price"

"The company was professional and responsive from the consultation to the office staff to the various people who worked on our project. I had tried to contact about 10 companies to get our heater/ on demand hot water heater replaced. Addario's was the only one who responded immediately and was able to fit us into their schedule to get the work done. We had contact with at least 8 staff people in various capacities, and all were professional, polite and knowledgeable. We also appreciated the senior discount for our project and assistance with the MassSave rebate process.. It has been difficult for us to find service people since we move to Gloucester. We were surprised that the company services this area and we would definitely use them again for plumbing or electrical services."
