Burst and Frozen Pipe Repair in Boston, MA
In Boston's triple-deckers, brownstones and row houses, pipes freeze in exterior walls, unheated basements and enclosed porches during January and February cold snaps. In a multi-family building one burst line can damage all three floors. Shut off the water and call a licensed plumber: Massachusetts does not allow homeowners to do their own plumbing repairs.

What is different about burst and frozen pipe repair in Boston?
Triple-deckers have a recurring weak point in the stacked rear porches, many of which were enclosed and now hold a pantry sink, a laundry hookup or the pipes for a rear bathroom. Old balloon-framed walls also let cold air travel up the cavities where supply lines run to the upper floors.
Heating matters as much as plumbing here. Many buildings are heated by steam or hot-water boilers, and when a boiler fails in a cold snap, both the heating pipes and the domestic water lines are at risk within hours. If the heat is out, shut off the water and drain what you can while you arrange repairs. Owners of rental units should make sure every floor knows where the shutoffs are.

Burst and Frozen Pipe Repair questions from Boston
Can I fix a burst pipe myself in Massachusetts?
You can and should shut off the water and limit the damage. The repair itself must be done by a licensed plumber under state rules, which do not make an exception for homeowners working on their own homes.
My heat is out and it is freezing. How do I protect my pipes?
Shut off the main water valve and open faucets on every floor, starting at the top, to drain the lines. Flush toilets to empty the tanks. Call for heating repair and tell the plumber the building has been without heat.
