Gas Line Repair in Sylmar, CA
In Sylmar the mains connection is the norm at 66% of households, with 2% on tank propane. Knowing which you have is the first step and it takes one look at the wall.
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 Sylmar, where 66% 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 Sylmar 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 Sylmar | Share |
|---|---|
| Utility (mains) gas | 66% |
| Bottled or tank propane | 2% |
| Electricity | 25% |
| Fuel oil and kerosene | under 1% |
| Wood and everything else | 7% |
Source: US Census Bureau, American Community Survey 5-year estimates, table B25040 (house heating fuel), 2023 release. Universe: 25,205 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. Sylmar sits about level with the state on mains and about level with it on propane. That is the gap a statewide number papers over, and the reason the figures above are this town’s rather than the state’s.
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 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 Sylmar requests are covered by the same line.
