J & B's Plumbing Co works out of Watertown, handling everyday plumbing along with gas fitting and drain and pipe camera inspections for homes, businesses, and municipal buildings across Massachusetts. The company says it's been at it since 1980, with more than 30 years of master-plumbing experience behind the crew, and describes its coverage as statewide with a focus on the Metrowest area. Its Google profile carries a 4.5-star average from 20 ratings, and reviews going back to 2021 describe a plumber that takes on the harder calls. A June 2026 review credits the crew with fixing a complicated sink install that a regular plumber and a handyman had both given up on, calling the pair sent out professional and quick to price the job. An independent directory listing echoes that with a short customer note about good service and communication. That said, the most recent stretch hasn't been spotless: a February 2026 review reports that a technician set a toilet tank lid directly on a marble countertop during a 90-minute visit, scratching it, while the humming-pipe noise that prompted the call went unresolved. It's the kind of complaint worth asking about directly before work starts. Its Massachusetts plumbing license (5150-PL-C) is active. For anything beyond a quick repair, get a specific scope and price up front and ask how the company handles accidental property damage on the job.

    These guys are fantastic. We had a very complicated sink install that our regular plumber and a handyman were unable to complete and we were referred to Jerry. He sent someone over that afternoon to look at it and then got back to me within hours with a price for the job. Jake and Jerry came the next business day and installed the sink perfectly. All of this was happening as our house was being listed for sale - so we were very stressed about it. These guys are so professional and knowledgeable. I knew that we were in great hands. If I wasn't planning on moving - they would be my new plumber. I can't thank them enough.

    I did not have a good experience with J&B’s. I had a humming noise that intermittently came from my pipes when I used water. I called the team to come investigate. While the plumber was here last week, he took off the toilet tank covers to inspect the toilets. He set the rough side of the tank lid down directly on the marble countertop, causing scratches which damaged the counter, and now need to be repaired.<br><br>During his 90 minute visit, the issue was not fixed or addressed. The plumber seemed very stressed and confused when the sound happened, and he had to call the boss for advice. The plumber was very friendly and professional behaving, but was unable to identify the cause of the humming sound. The boss (who was not onsite) did have a few ideas related to my master pressure valve and provided a quote for future work. For this assessment which did not fix the issue or identify the source of the humming sound, but did cause damage, I was charged $400.<br><br>I was not pleased with this experience or confident in the path forward, so I called a second plumber to come assess. They localized the issue to one sink/faucet fixture. During their visit, the plumber caused no damage to my house, found and isolated the issue, and charged me $180 for the visit. Going forward, I’ll be using this other company, not J & B’s.

    I have had great experiences with Jerry. We recently discovered that our water heater was leaking steadily and our basement was filling up quickly. Within 30 minutes he sent his worker over and diagnosed and took care of the problem. We ended up needing a replacement water heater and Jerry was able to look up to see if we still had a warranty. We did and saved us money purchasing a new one! He also recommended installing a leak detector which we’re glad we did. Jerry does excellent work, is honest, and makes sure that his customer is satisfied.

    I can’t recommend J & B Plumbing enough. I had an overnight emergency and they called me within 10 minutes of me talking with their answering service. Jerry moved his morning around to accommodate us due to the urgency of the matter and followed through with amazing help and service. He even talked me through some updates we want to start thinking about but did not pressure us in any way to make any unnecessary/non-urgent changes right now. Great customer service, exceptional speed and service. I will use J & B again.

    I hired J&B’s of Watertown<br>to replace a dishwasher and garbage disposal and haul away old dishwasher on 8/22/24. Two guys came and were there for 3.5 hours. The invoice said 9 hrs total. They replace drain on sink and add-on Dahl shut off. The bill came to $1980. The owner said he did me a favor getting it install the same day. I was expecting a $600 bill. Shame on me for not getting a quote but they were recommended to me. They did the job but slow walked it. Only use if you can a quote.
