Gas Line Repair in Catonsville, MD
Catonsville is a mains gas town — 55% of households heat with utility gas. The useful thing to know before anything goes wrong is where the utility’s responsibility stops.
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. 55% of homes in Catonsville 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 Catonsville 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.

|---|---|
| Utility (mains) gas | 55% |

Read it as fuel rather than as plumbing. The share on utility gas is how many houses burn it, which is the nearest thing published to how many have a service line. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Maryland as a whole, 45% of households are on mains gas and 3% on tank propane. Catonsville sits 9 points above the state on mains and 2 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
The single most dangerous thing most people will ever do to a gas line is put a spade through it. PHMSA calls excavation damage the leading cause of pipeline incidents; 8-1-1 is a nationwide toll-free number to call before any excavation, and calling it gives a 99 percent chance of avoiding an incident.

What to ask whoever quotes it
Ask them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

Checking a plumber in Maryland
Maryland licenses are issued by the Maryland State Board of Plumbing, Department of Labor, which publishes a public search you can use 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 Catonsville requests are covered by the same line.
