Looking for a plumber in Waltham, MA? IS Plumbing covers Waltham Center, Moody Street, Warrendale and Piety Corner with plumbing, water heaters, boilers, gas fitting and drain service.
Waltham's mix of Victorian and colonial homes, dense two-families near Moody Street and newer construction toward the Lexington line keeps us doing a bit of everything: repiping older supply lines, water heater and boiler replacement, gas fitting, drain work and bathroom remodels. Always pulled under the proper City of Waltham permits and inspected.
Waltham's industrial bones — the Watch City mills along the Charles, since converted to lofts and offices — sit alongside street after street of two-families off Moody Street and postwar singles on the north side. The city is on MWRA water, and the private-side plumbing matches the housing's age: galvanized supply and cast iron in the older stock, first-generation systems aging out in the rest.
Permits file with the City of Waltham and we carry every job through inspection. Two-family work is the local staple — separated shutoffs, per-unit water heaters, gas piping brought to code — plus steady boiler replacements in homes that still heat with a unit from decades back.
"True professionals — respectful and tidy. I've worked with them three times. The last was a burst water main; they were the only ones who responded fast, offered a solution, and got it done."
"Fantastic experience. They did the plumbing for two bathroom renovations — our master bath and the kids' bath — and the whole process was smooth, professional, and on time."
"We hired IS Plumbing to replace a number of fixtures and toilets. Very professional crew and a great job. Highly recommend them for all your plumbing needs."
