Gas Line Repair in Gaithersburg, MD
Gaithersburg runs on both: 43% mains gas, 2% tank propane, 45% on gas of some kind. The two arrangements answer the ownership question completely differently.
Read this first
In Gaithersburg, 43% of homes are on mains gas and 2% on bottled, so the town average settles nothing about any one address. Mains gas ends the utility's regulated line at the meter outlet; a tank supply has no such boundary.
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 Gaithersburg is supplied
In a town with both, the useful page is the one about the arrangement you actually have. The meter is the tell: if there is one, there is a service line behind it and a boundary at its outlet.
| Households in Gaithersburg | Share |
|---|---|
| Utility (mains) gas | 43% |
| Bottled or tank propane | 2% |
| Electricity | 49% |
| Fuel oil and kerosene | 4% |
| Wood and everything else | 2% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 50,758 occupied housing units. 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. Gaithersburg sits 2 points below the state on mains and 1 point below it on propane. That distance from the state average is the whole argument for publishing a town figure at all.
Before anyone digs on the property
Digging is the risk, not age or material. PHMSA names excavation damage as the leading cause of pipeline incidents and puts a caller’s chance of avoiding one at 99 percent. 8-1-1 is nationwide, toll-free, and costs nothing.

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. We serve Gaithersburg for plumbing that has nothing to do with gas.
