Gas Line Repair in Merrimack, NH
22% of households in Merrimack 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
No regulated utility service line is involved where the gas comes out of a tank, and 22% of homes in Merrimack run on propane. The tank and the buried line from it are governed by the supply agreement rather than by a meter boundary, which changes who is responsible for what.
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 Merrimack 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 Merrimack | Share |
|---|---|
| Utility (mains) gas | 36% |
| Bottled or tank propane | 22% |
| Electricity | 9% |
| Fuel oil and kerosene | 28% |
| Wood and everything else | 5% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 10,378 occupied housing units. The table counts heating fuel rather than pipework. A house on mains gas almost certainly has a service line; the Census does not say so directly and neither do we. 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. Merrimack sits 11 points above the state on mains and 4 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
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 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. Gas is one part of what Merrimack calls us about.
