Gas Line Repair in Chelsea, MA
Most of Chelsea is on the gas main: 56% of households. That means a meter on the wall and a service line under the ground, and a boundary between them that federal rules put in a specific place.
Read this first
The utility's regulated line ends at the meter outlet and the piping beyond it belongs to the property owner. That boundary decides most gas line questions in Chelsea, where 56% of households heat with utility gas and a buried service line runs from the street on most properties.
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 Chelsea is supplied
49 CFR § 192.3 fixes the end of the service line at the meter outlet. It is a precise answer to a narrow question, and it is not the same as who is responsible for repairs, which varies by utility and by state.
Establishing which side of the meter a fault is on is the first thing any contractor should do, because it decides whether they are the right person to call.
| Households in Chelsea | Share |
|---|---|
| Utility (mains) gas | 56% |
| Bottled or tank propane | 2% |
| Electricity | 33% |
| Fuel oil and kerosene | 8% |
| Wood and everything else | 1% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 13,522 occupied housing units. B25040 is a fuel count, not an infrastructure count. It tells you what burns in these houses, from which the arrangement follows — but it is an inference, not a meter reading. Service line definition: 49 CFR § 192.3, via PHMSA interpretation PI-12-0003.
Across Massachusetts as a whole, 56% of households are on mains gas and 4% on tank propane. Chelsea sits about level with the state on mains and 2 points below 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 what is being left behind: where the new pipe runs, at what depth, and whether you will get a photograph of the trench before it is filled. That record will not exist anywhere else and you will want it eventually.

Checking a plumber in Massachusetts
Massachusetts licenses are issued by the Massachusetts Board of State Examiners of Plumbers and Gas Fitters, 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. Other Chelsea requests are covered by the same line.
