Gas Line Repair in Wellesley, MA
62% of households in Wellesley take mains gas. Two things follow: there is a buried line on the property, and somebody other than you is responsible for part of it.
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 Wellesley, where 62% 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 Wellesley is supplied
A buried run from the street to a meter, and piping onward through the property. Federal rules end the service line at the meter outlet; what comes after is customer piping.
The piping people forget they own is the buried run from the meter to a detached garage, a grill or a pool heater. That is theirs, and it may not be marked when somebody comes to locate lines.

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 4,121 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. Wellesley sits 6 points above the state on mains and 2 points below 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 them to describe the fault before they price it. "The line needs replacing" is not a diagnosis, and on a buried run the difference between one damaged point and a line at the end of its life is most of the cost.

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. Gas is one part of what Wellesley calls us about.
