Our Capabilities

Expert Craftsmanship & Reliable Solutions

Every service is backed by our licensed technicians and complete warranty.

Emergency Pipe, Leak & Frozen Line Repair

Burst or frozen pipes don't wait for business hours — and neither do we. We thaw and repair frozen supply lines, stop active leaks at the source, and identify the underlying cause so the same pipe doesn't fail again next cold snap.

Book Service →

Galvanized Repiping & Cast-Iron Stack Replacement

Many Waltham-area homes still run on decades-old galvanized supply lines and cast-iron sewer stacks that corrode from the inside out. We repipe to modern copper or PEX and replace failing stacks with code-compliant PVC or cast iron, restoring water pressure and ending chronic clogs.

Book Service →

Hydronic Boiler Service & Heating Maintenance

We service, repair, and tune hot-water and hydronic heating systems, with a focus on freeze protection — proper glycol levels, insulated runs in vulnerable spaces, and reliable circulation — so your boiler keeps the house warm through the worst Massachusetts winter.

Book Service →

Bathroom & Kitchen Remodeling with Gas Fitting

From full bathroom and kitchen remodels to licensed gas line installation for ranges, dryers, and generators, we handle the rough-in, fixture setting, and final connections — one accountable crew for the plumbing and gas work behind your renovation.

About Us

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every week, repiping corroded galvanized supply lines, replacing failing cast-iron sewer stacks, and upgrading outdated plumbing to modern code — cleanly, carefully, and with as little disruption to your household as possible.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.
