Gas Line Repair in Derwood, MD
With 43% of households on the main and 2% on a tank, Derwood has no single answer to who owns the pipe. It depends which of the two you are.
Read this first
Derwood splits between mains and tank gas, at 43% on utility gas and 2% on bottled. Which one a property has decides where responsibility changes hands: a meter outlet marks the boundary on mains gas, while a tank puts the whole installation on the owner.
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 Derwood 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.

What B25040 measures is the heating fuel, not the connection. It is the closest published proxy for whether there is a buried service line here, and it is a proxy.

Across Maryland as a whole, 45% of households are on mains gas and 3% on tank propane. Derwood sits about level with 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
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 whether the job needs a permit and who is pulling it. Gas work is separately permitted in most jurisdictions and the answer should not be you.

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 Derwood goes through this number as well.
