J C Jacobs Plumbing Co is a Norwood plumbing company, and a 2023 Google customer said it answered the call right away and replaced their hot water heater the same day. A 2022 Google customer said the plumber was on time and polite, and that the office staff and the plumber were easy to deal with. The company says it has been family owned and operated since 1970. Joseph Jr Jacobs's Massachusetts plumber license, 12537-PL-M, is active on the state registry. The Better Business Bureau gives the company an A+ grade, and on Google it holds 4.1 stars from 28 ratings. A 2024 Google customer said the company had installed a gas boiler for them in 2016 and did that installation very well. That 2024 customer later called about moving a carbon monoxide detector below a drop ceiling to meet code, and wrote that the company sent a plumber who declined to move the existing detector and instead started opening a sealed battery detector, then left within 2 minutes when told that was not what was asked for. The same 2024 customer was billed $180 for a service call, and wrote that no one explained the company could not do anything involving electrical work or that a 10 year sealed battery detector could easily have been installed. In a 2022 Google review, a customer said they got the run around for close to two months, was charged $100 to tighten a clamp, and had to call every other day. That 2022 customer wrote that the company then said it was too busy to get to the job, that the receptionist hung up on them, and that another plumber got the job done in 2 days.
Chris was great.
I feel the need to call out this business for neither listening to, nor addressing my request for service, and yet, brazenly invoicing me for the "pleasure". When Joe Jacobs (then the plumbing inspector for the Town of Sharon) owned this company, they were recommended by ANOTHER plumber (who was unable to undertake the job) to replace a gas boiler in 2016. The boiler had blown as a result of a poor contract repair job by the utility company, and Joe's company did the installation very well. THEY insisted on hiring an electrician to hard wire a carbon monoxide detector up above the plane of a drop ceiling, where the ceiling tiles were not in place. Recently, however, when the drop ceiling tiles were replaced, it was brought to my attention that we needed the detector to be moved BELOW the ceiling to meet code. I called the company, and explained the problem, both to the scheduler and to "Dave," who now apparently owns the company. Not bothering to explain to me that (1) they could not do anything involving electrical work, and (2) the code requirements had been loosened, and that I could easily have installed a 10 year sealed battery detector, they sent out a plumber, who declined to move the existing detector, but instead started opening a sealed battery detector. I told him that wasn't what I had asked for, and he left within 2 minutes. I was billed $180 for a "service call," where the 2 simple statements above on the phone would have saved them and me the inconvenience (YES, I paid the invoice, not wanting to get into an argument), but this kind of shoddy and irresponsible "business" practice deserves to be exposed.
