Gas Line Repair in Gwynn Oak, MD
54% of households in Gwynn Oak heat with utility gas, which means a buried service line runs from the street to a meter on most of these properties. Where that line ends is a federal definition, and it decides who repairs what.
Read this first
A buried service line and a meter sit on most properties in Gwynn Oak, where 54% of homes are on mains gas. Federal rules end the utility's service line at the meter outlet, so everything downstream of the meter is the owner's to maintain and repair.
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 Gwynn Oak is supplied
Two questions hide behind one. Where does the regulated line end — the federal answer is the meter outlet. And who pays for a repair on either side of that — which is tariff and state regulation, and varies.
The second one is the one that costs money, and it is answered by your utility rather than by any rule you can look up.

|---|---|

Across Maryland as a whole, 45% of households are on mains gas and 3% on tank propane. Gwynn Oak sits 9 points above the state on mains and about level with it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
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
If any part of the job is in the ground, ask when they are calling 8-1-1 and whether a private line may be in the way. Both answers should come before the excavation, not during it.

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. Gas is one part of what Gwynn Oak calls us about.
