24/7 Emergency Pipe & Leak Repair Service

Burst supply lines, slab leaks, and failed shutoff valves don't keep business hours — and neither do we. Our on-call plumbers isolate the break, make permanent code-approved repairs, and dry out affected areas to prevent mold and structural damage.

24/7 Emergency Pipe & Leak Repair

Galvanized Repiping & Water Line Upgrades

Many pre-1960 homes in Cambridge, Somerville, and Brookline still run on corroded galvanized steel that restricts flow and sheds rust into your water. We repipe with PEX or copper in clean, routed runs — restoring full pressure and often in a single visit.

Cast-Iron Sewer Stack & Drain Replacement

Century-old cast-iron stacks rust from the inside out, causing chronic clogs, sewer gas, and eventual collapse. We scope the line with a camera, then replace compromised sections with PVC or no-hub cast iron, including proper venting for multi-family buildings.

Boiler Service & Hydronic Freeze Protection

We service and repair gas and oil-fired hydronic boilers, and we winterize heating loops against New England cold snaps — antifreeze concentration checks, air purges, low-water cutoff testing, and emergency no-heat response throughout the winter months.
