Gas Line Repair and Installation in Boston, MA
If you smell gas, leave the building and call 911 or your gas utility from outside. In Massachusetts, gas piping must be installed and repaired by a licensed gas fitter with a permit, and many plumbers hold both licenses. Homeowners are not permitted to do this work themselves.

What is different about gas line repair and installation in Boston?
The licensing detail matters when you call for help: ask specifically for someone licensed as a gas fitter, not only as a plumber. The Board of State Examiners of Plumbers and Gas Fitters licenses both trades, and the license can be verified with the state.
Boston's housing adds its own considerations. Old buildings may still have original black-iron gas piping, abandoned lines to former gas lights or ranges, and appliances added over a century by different owners. When the utility finds a leak or an unsafe appliance it can shut off and tag the service or the appliance, and it is restored only after a licensed gas fitter makes the repair and it passes inspection. In a multi-family building, find out whether the problem is on a shared line or within one unit.

Gas Line Repair and Installation questions from Boston
Can a plumber fix a gas leak in Massachusetts?
Only if they also hold a gas fitter license. Massachusetts licenses plumbers and gas fitters separately, though many tradespeople hold both. Ask for the gas fitter license number.
The gas company red-tagged my appliance. What happens next?
A red tag means the utility found an unsafe condition and shut off the appliance or service. A licensed gas fitter needs to correct it, usually with a permit and inspection, before it can be turned back on. Do not remove the tag or relight it yourself.
