Gas Line Repair in Greenfield, NH
31% of households in Greenfield heat with bottled or tank propane. On propane there is no utility service line and no meter boundary — the tank, the regulator and the buried run to the house are all the property owner’s.
Read this first
31% of households in Greenfield use bottled or tank gas, which puts the supply on the property rather than under the street. There is no utility service line and no meter boundary: the tank, the regulator and the line to the house belong to the owner or the gas supplier by 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 Greenfield is supplied
Propane changes the ownership question completely. There is no utility that owns a length of it, which means there is nobody else whose problem part of it is.
It also changes the risk in one specific way: propane is heavier than air and collects in low spaces rather than dispersing upward. Basements, pits and crawl spaces are where it goes.
| Households in Greenfield | Share |
|---|---|
| Utility (mains) gas | under 1% |
| Bottled or tank propane | 31% |
| Electricity | 8% |
| Fuel oil and kerosene | 37% |
| Wood and everything else | 24% |

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 New Hampshire as a whole, 25% of households are on mains gas and 17% on tank propane. Greenfield sits 25 points below the state on mains and 14 points above 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
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 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 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. Gas is one part of what Greenfield calls us about.
