Pipe Repair in Boston, MA

Pipe Repair in BostonPipe repair in Boston usually involves one of two things: old galvanized supply lines that have rusted shut from the inside, or pipes that froze and split during a cold snap. Triple-deckers and row houses often have supply risers running through exterior walls and unheated porches, and a failure on one floor can leak into the units below. A repair visit is often the moment to decide whether a building needs a full repipe.

What’s different about pipe repair in Boston

Galvanized risers in multi-family homes

Supply risers that serve several units corrode and restrict flow, causing weak pressure on upper floors.

Exterior-wall and porch plumbing

Back porches and exterior walls in older homes are the most common freeze points.

Permits for repiping

Repiping and many repairs require a licensed plumber and permit under the Massachusetts plumbing code.

Pipe Repair in Boston: questions

Should a Boston triple-decker be repiped all at once?

Repiping the risers and each unit together is usually more efficient than fixing one floor at a time, and it restores pressure on upper floors.

What should I do if a pipe bursts upstairs in a Boston building?

Shut off the unit or riser valve, cut power to wet areas if safe, and alert the other units before calling a plumber.
