Gas Line Repair in Derry, NH
Tank propane heats 22% of homes in Derry. There is no service line here in the federal sense, which sounds like a technicality and is actually the whole difference.
Read this first
Tank gas serves 22% of households in Derry. With no utility main and no meter, the boundary that matters on mains gas does not exist here, and the tank, regulator and buried line are the owner's or the supplier's under contract.
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 Derry is supplied
A tank, a regulator, and buried line between them and the house. All of it is the property owner’s, and none of it sits under the federal service line definition that governs a mains connection.
That makes the buried run private buried line — which is exactly the sort a standard locate may not mark before somebody digs.
| Households in Derry | Share |
|---|---|
| Utility (mains) gas | 7% |
| Bottled or tank propane | 22% |
| Electricity | 17% |
| Fuel oil and kerosene | 47% |
| Wood and everything else | 7% |

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. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across New Hampshire as a whole, 25% of households are on mains gas and 17% on tank propane. Derry sits 19 points below the state on mains and 5 points above it on propane. A state figure would flatten exactly that difference, which is the reason these pages are built town by town instead.
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 how much gas work they actually do, not whether they can. Gas is separately licensed in most jurisdictions and plenty of capable plumbers do very little of it.

Checking a plumber in New Hampshire
The authority is the New Hampshire Office of Professional Licensure and Certification, Mechanical Safety and Licensing Board. New Hampshire licenses plumbers but publishes no online licensee search, so verification means contacting the office directly.
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 Derry for plumbing that has nothing to do with gas.
