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 Cabin John is supplied
Where both are common, so is the assumption that they work the same way. They do not: on mains, part of the system is somebody else’s responsibility; on propane, none of it is.

The table counts heating fuel rather than pipework. A house on mains gas almost certainly has a service line; the Census does not say so directly and neither do we. 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. Cabin John sits about level with the state on propane; its mains share carries too wide a margin of error to compare. 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
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
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. We serve Cabin John for plumbing that has nothing to do with gas.
