Gas Line Repair in Rockville, MD
Rockville is a mains gas town — 59% 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
A buried service line and a meter sit on most properties in Rockville, where 59% 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 Rockville is supplied
On a mains connection there are two systems, not one, and the meter divides them. The federal definition puts the end of the regulated service line at the meter outlet; local code governs everything beyond it.
Practically, that means part of the problem may not be yours at all — and part of it certainly is.
| Households in Rockville | Share |
|---|---|
| Utility (mains) gas | 59% |

B25040 is a fuel count, not an infrastructure count. It tells you what burns in these houses, from which the arrangement follows — but it is an inference, not a meter reading. 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. Rockville sits 14 points above the state on mains and 2 points below it on propane. The state number would tell you something true about the state and very little about here, which is why it is not the number above.
Before anyone digs on the property
Before any digging — a fence post as much as a foundation — call 8-1-1. It is a nationwide toll-free number, it costs nothing, and PHMSA puts the chance of avoiding an incident afterwards at 99 percent.

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 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 Rockville calls us about.
