Gas Line Repair in Columbia, MD
With 41% of households on the main and 1% on a tank, Columbia has no single answer to who owns the pipe. It depends which of the two you are.
Read this first
Mains gas heats 41% of homes in Columbia and tank gas another 1%. 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.

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 Columbia is supplied
Mains and tank gas differ in ownership, in who to call, and in how the gas behaves if it escapes — propane is heavier than air and collects low rather than rising.
What they do not differ in is the emergency response, which is the same for both and is the first thing on every page of this site.

|---|---|

B25040 records what heats the house, which is the best available guide to whether a property has mains gas or a tank — it does not count service lines directly. 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. Columbia sits 5 points below the state on mains and 3 points below it on propane. Averages are where this kind of difference disappears. The figures on this page are the town’s own for that reason.
Before anyone digs on the property
PHMSA describes excavation damage as the leading cause of pipeline incidents, and puts the effect of one free phone call plainly: someone who calls 8-1-1 before they dig has a 99 percent chance of avoiding an incident, injury, harm to the environment and even death.

What to ask whoever quotes it
Ask what they will do about the existing load. Adding an appliance changes what the existing pipe has to deliver, and sizing is a calculation against the whole system rather than the new run alone.

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 Columbia calls us about.
