Gas Line Repair in Montclair, CA
Utility gas heats 71% of homes in Montclair. That puts a buried service line and a meter on most properties here, and puts the boundary between the two sides of the system exactly at the meter.
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 Montclair, where 71% 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 Montclair is supplied
The meter is doing two jobs: measuring gas, and marking where the federally regulated line stops. The second is the one that matters when something fails.
Buried customer piping past the meter — out to a garage, a grill, a generator — is the owner’s, and it is easy to forget it exists until somebody digs.
| Households in Montclair | Share |
|---|---|
| Utility (mains) gas | 71% |

Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 10,267 occupied housing units. 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 California as a whole, 65% of households are on mains gas and 2% on tank propane. Montclair sits 6 points above 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
One free call before any excavation. PHMSA is blunt about why: excavation damage is the leading cause of pipeline incidents, and 8-1-1 raises the odds of avoiding one to 99 in 100. It applies to a fence post as much as a foundation.

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 California
California licenses are issued by the Contractors State License Board, which publishes a public search you can use before work begins. California licenses the C-36 plumbing contractor; there is no state journeyman license.
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 Montclair requests are covered by the same line.
