Customers say: True professional

"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."

"Within hours of my inquiry on a Saturday, Bill was out to my house to assess my needs. I needed a new water heater and my AC repaired. I knew I would be looking at a lot of money, because I had other quotes. His price was amazing and the job was completed in less than a week! I would highly recommend this company."

"As a home owner, you do your best to fix things around the house. However, there comes a point where you need to call in the professional. Forbes Plumbing came to the rescue and fixed persistent leaking pipe fixture. Forbes responded in a timely manner with an estimate as well as came out as soon as I approved the estimate. I am extremely happy with the work done. I will definitely utilize this company for my next plumbing project(s)."

"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

"They came to my home showed me what needed to be done and they went and got the water heater. When they came back a short time later they had the tank and installed it in an hour with new pipes and a new shout off that I can do."
