JLM Plumbing is a Massachusetts plumbing company whose customers repeatedly describe fast diagnosis, careful repairs, and clear communication. Recent reviews cover boiler replacement, bathroom repiping and fixture installation, water-heater repairs, leak finding, and water-treatment work. The strongest theme is practical problem-solving. One homeowner says JLM found a faulty water-heater component that another plumber had missed; another describes a secure washing-machine pipe repair followed by cleanup, while a property manager says the team has handled work across more than 150 homes and apartments over several years. The available reviews are consistently positive, though the written history is concentrated in 2025–2026. Thumbtack lists five stars from eight ratings, 14 projects, and nine years in business, and lists plumbing, handyman, water treatment, heating, appliance, and emergency-plumbing services. JLM looks suited to residential plumbing repairs, water heaters, boilers, bathroom work, and leak diagnosis. Confirm the exact scope, parts, timing, and any related drywall or electrical work before approving the estimate.

Amazing, honest and hardworking people. Luan was very polite, straightforward and solved all of the plumbing issues in my house. Thank you!
I had a great experience with Luan and his team at JLM Plumbing & Heating INC. They replaced our boiler quickly and were incredibly punctual throughout the process. Their service was excellent — from a thorough diagnosis to a clean and efficient installation. The pricing was very reasonable, and the overall professionalism made the entire experience smooth and stress-free. I've already decided to have them back for an irrigation meter installation, and they'll be my go-to for all HVAC and plumbing needs going forward. Highly recommended!
JLM redid all the plumbing in my bathroom. They installed a double shower, bathtub, and new faucets. Everything came out perfect, top-notch service!
Quality service excellent price fully qualified company punctually invested I recommend it is a company that I will put in all my projects thank you Luan and team for the beautiful work very satisfied.
i was having trouble with my water heater and the other plumber i called said it would have to be entirely replaced. called JLM and they found the problem immediately, explained to me that it was just a faulty component and charged me a reasonable price. really excellent work
