Gas Line Repair in Bryn Mawr, PA
Most of Bryn Mawr is on the gas main: 63% of households. That means a meter on the wall and a service line under the ground, and a boundary between them that federal rules put in a specific place.
Read this first
Responsibility changes hands at the meter outlet. The line under the ground between the street and the meter is the utility's up to that point, and the yard line and house piping after it are the property owner's. 63% of homes in Bryn Mawr heat with utility gas.
Source: US Census Bureau, American Community Survey table B25040; the service line boundary is 49 CFR § 192.3.
If you smell gas right now
Leave the building on foot. Do not use a phone or a light switch inside. Call 911 and your gas utility from somewhere else, and do not call us — we are a referral service, not an emergency line. The full list, in order.
How Bryn Mawr is supplied
Everything upstream of the meter outlet is the operator’s service line under 49 CFR § 192.3. Everything after it is customer piping under local code. That single point is what a contractor establishes before quoting.
It is also why the answer to "is this my problem" is sometimes no, and why it is worth asking before assuming it is yes.

|---|---|

Across Pennsylvania as a whole, 50% of households are on mains gas and 5% on tank propane. Bryn Mawr sits 13 points above the state on mains and 3 points below it on propane. That spread is what a state average hides, and it is why this page carries the town’s own figures rather than inheriting them.
Before anyone digs on the property
PHMSA describes excavation damage as the leading cause of pipeline incidents, and puts the effect of one free phone call plainly: someone who calls 8-1-1 before they dig has a 99 percent chance of avoiding an incident, injury, harm to the environment and even death.

What to ask whoever quotes it
Ask which side of the meter the work is on before anything else. On the utility side it may not be a contractor job at all, and a quote that has not established that has not established whose problem it is.

Checking a plumber in Pennsylvania
Pennsylvania has no state license for plumbers. Its Department of Labor and Industry states it has no jurisdiction and keeps no records of which municipalities require one, so the only reliable answer is your own city or township. Start here. Ask the contractor which municipality licenses them and confirm it with that office before work begins.
Gas work is separately permitted and separately licensed in most jurisdictions, so ask specifically about gas rather than plumbing in general.
For repair work, not for a suspected leak.If you can smell gas, leave and call 911 or your utility from outside; this is the wrong number for that. For everything else — a line, a meter, an appliance connection — we will route you to a contractor covering your area, free of charge to you. Other Bryn Mawr requests are covered by the same line.
