Gas Line Repair in Knoxville, MD
About 18% of homes in Knoxville are on mains gas and 7% on propane. The split matters because a meter is a legal boundary and a propane tank is not.
Read this first
In Knoxville, 18% of homes are on mains gas and 7% 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 Knoxville 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 Knoxville | Share |
|---|---|
| Utility (mains) gas | 18% |
| Bottled or tank propane | 7% |
| Electricity | 33% |

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. Knoxville sits 27 points below the state on mains and about level with 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
Excavation damage remains the leading cause of pipeline incidents according to PHMSA. That is not a fact about pipelines so much as a fact about gardening, and the prevention is one free call to 8-1-1 before the first spade goes in.

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 Knoxville for plumbing that has nothing to do with gas.
