Gas Line Repair in Germantown, MD
Neither arrangement dominates Germantown: 37% mains gas, 2% tank propane. This page applies to both, and the difference between them is the first thing to establish.
Read this first
Mains gas heats 37% of homes in Germantown and tank gas another 2%. The difference matters more than the fault does at first, because only one of the two has a meter outlet where the utility's responsibility stops.
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 Germantown is supplied
Two arrangements in one town, and the difference is not cosmetic. A mains connection has a meter, and 49 CFR § 192.3 ends the regulated service line at its outlet. A propane installation has no meter boundary and belongs to the property owner end to end.
Establish which you have before anything else on this page applies.

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. Germantown sits 8 points below the state on mains and 1 point 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
One free call before any excavation. PHMSA is blunt about why: excavation damage is the leading cause of pipeline incidents, and 8-1-1 raises the odds of avoiding one to 99 in 100. It applies to a fence post as much as a foundation.

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. Non-emergency work in Germantown goes through this number as well.
