About J.W. Langton Plumbing & Heating L.L.C
J.W. Langton Plumbing & Heating is a family-run plumbing and heating company based on Trapelo Road in Waltham, proudly serving homeowners across Newton, Lexington, Belmont, Weston, Lincoln, Watertown, and Woburn. Led by Joe Langton, our team has built a 4.9-star reputation the old-fashioned way — showing up on time, communicating clearly, and treating every home like it's our own. From a frozen pipe on a Sunday night to a full bathroom remodel, one call or one text puts a licensed master plumber on the way.
Greater Boston's housing stock demands a plumber who understands what's behind the plaster. We work in historic triple-deckers and century-old colonials every week, repiping corroded galvanized supply lines, replacing failing cast-iron sewer stacks, and upgrading outdated plumbing to modern code — cleanly, carefully, and with as little disruption to your household as possible. As a licensed gasfitter, we also handle gas line installations for ranges, dryers, and generators, and we keep hydronic boiler systems properly protected through harsh Massachusetts winters with thorough freeze-protection and maintenance service.
What sets us apart is follow-through. We don't just fix the leak in front of us — we point out the worn fitting or aging valve that will become tomorrow's emergency, so you can decide what to address on your schedule and budget. Straightforward recommendations, meticulous workmanship, and a follow-up call to make sure everything held. That's why so many of our neighbors in Waltham and the surrounding communities call us first, every time.
