Gas Line Repair in Durham, NH
Neither arrangement dominates Durham: 20% mains gas, 14% tank propane. This page applies to both, and the difference between them is the first thing to establish.
Read this first
Mains gas heats 20% of homes in Durham and tank gas another 14%. 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.
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 Durham 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 Durham | Share |
|---|---|
| Utility (mains) gas | 20% |
| Bottled or tank propane | 14% |
| Electricity | 18% |
| Fuel oil and kerosene | 40% |
| Wood and everything else | 8% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 2,901 occupied housing units. This is the heating-fuel table. It does not enumerate service lines, and no table does at this geography; what it gives is the best available indication of which arrangement a property is on. 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. Durham sits 6 points below the state on mains and about level with 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
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 which side of the meter the work is on before anything else. On the utility side it may not be a contractor job at all, and a quote that has not established that has not established whose problem it is.

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. Non-emergency work in Durham goes through this number as well.
