In La Mesa, a gas odor means going outside first and calling 911 and SDG&E at 1-800-611-7343 once you are clear of the house. Many homes here date to around 1970, so gas piping and connectors are often original or patched. Call the number on this page to be connected with a local plumber in La Mesa.

Warning signs worth acting on
- Any smell like sulfur or rotten eggs. Get out and call from the yard or the street, not from inside.
- A brass or plastic-coated connector behind the range or dryer that looks old, kinked or cracked
- A shutoff valve that is frozen in place or won't turn fully
- Rust or scaling on the outdoor pipe near the meter
- A furnace that lights, sputters and goes out
- Scorch marks or soot near a gas fireplace insert
Leave the odor to SDG&E first. The rest are good reasons to schedule a plumber.
Why La Mesa homes need a closer look
La Mesa has an older housing stock: the median home was built around 1970. Gas piping from that period was usually threaded steel, and it often outlasts the house's other plumbing. The trouble spots are the additions and the ends of the lines. Decades of remodels can leave branches capped badly, tees added without checking pipe size, and appliance connectors that should have been replaced long ago. Hillside lots near Mount Helix sometimes have long buried runs to a lower patio or a spa, and those are the owner's responsibility past the meter.
SDG&E is La Mesa's gas utility. Permits come from the City of La Mesa Building Division at City Hall, 8130 Allison Avenue. The City notes that a plumbing permit may be needed for any addition or change to a building's existing system, while simple fixture repair normally doesn't need one. Applications and plans are accepted electronically through the MaintStar Permit Portal. Water heater replacement also requires a permit in La Mesa, which matters if a new gas heater is part of the job.
Cost factors
- Whether the job is a single fitting repair or replacing a section of corroded pipe
- Access: crawl space, attic or slab, and how much finish has to come off
- Upsizing the line for a tankless heater or a larger range
- Yard trenching on sloped lots
- Permit and inspection through the City
What to expect on the call
You'll be connected with an independent plumber who works in La Mesa. Explain what you've noticed or what you want added, how old the house is if you know, and where the meter is. The plumber can tell you whether a pressure test of the whole system makes sense before any new branch is added, and how the permit will be pulled.
