Repiping & Plumbing Services in Los Angeles
Repiping Los Angeles Homes & Apartment Buildings
Los Angeles has some of the oldest housing stock in Southern California — Craftsman, Spanish, and mid-century homes from the 1910s through the 1950s, most of them plumbed with galvanized steel that’s now a century into a 50-year lifespan. The result: rusty water, chronic pressure problems, and pinhole leaks that never stop coming back. We repipe single-family homes across the city, and we’re one of the few companies purpose-built for apartment and multifamily repipes — phased unit-by-unit so tenants stay in place and water is back on every evening.
Gas Line Repair & Replacement in Los Angeles
Gas is what Los Angeles calls us about most, and the reason is the age of the pipe under the city. Homes built before the 1940s — the bungalows across Boyle Heights, El Sereno, Highland Park and Eagle Rock, and the Spanish and Craftsman stock through Mid-City — were plumbed in black iron, joined with threaded fittings sealed by a compound that hardens and shrinks over eighty or ninety years. Corrosion begins where the pipe meets soil, where it passes through a slab, and at every threaded joint. That is why failures here cluster at the meter riser, along the run to a detached garage or rear unit, and at the connections behind older wall furnaces.
If SoCalGas has already been out and red-tagged the meter, service stays off until the system holds a pressure test and passes inspection. The sequence we work to is the same every time: locate the failure, repair or replace the affected run, pull the permit with LADBS, hold the test for as long as your inspector requires, and coordinate the utility's return so the gas comes back on the same visit wherever that is possible.
Two Los Angeles situations come up constantly. The first is added load — the city's ADU boom means a great many gas lines sized for a 1930s house are now being asked to carry a range, a dryer and a tankless heater as well. When the existing pipe cannot carry it, the fix is upsizing the run, not patching it. The second is multifamily. LA's apartment stock often runs a house meter plus individual unit lines, and a failure on a shared run affects every tenant at once, so the work has to be sequenced around occupancy rather than shut down for days.

Frequently Asked Questions
Which parts of Los Angeles do you serve?
All of them — from Boyle Heights and Highland Park to Mid-City, South LA, and the Westside. Our Montebello headquarters sits minutes east of downtown, so no LA neighborhood is far.
Do you repipe apartment buildings in Los Angeles?
Yes — it’s a specialty. We repipe apartments, condos, and HOA buildings in phases, unit by unit, with water restored by the end of each workday and tenant notices provided. See our apartment and multifamily repiping service for details.
My LA home was built in the 1930s. Repair or repipe?
Homes of that era were plumbed with galvanized steel that’s far past its life. If you’re seeing repeat leaks, rusty water, or weak pressure, spot repairs are treating symptoms — a copper or PEX repipe is the fix that lasts.
Do you handle LADBS permits and inspections?
Yes. Repipes, sewer replacements, and gas work in the City of Los Angeles require permits through LADBS — we pull them, schedule inspections, and deliver code-compliant work.
What should I do about a gas leak in Los Angeles?
Leave the building, don’t create sparks, and call SoCalGas at 1-800-427-2200 or 911 from outside. Once the utility makes it safe, call us at 833-673-2577 — we locate the leak, repair the line, and handle the pressure test the utility requires.
SoCalGas red-tagged my meter in Los Angeles. How fast can the gas come back on?
Usually the same visit, provided the repair passes. We locate the failure, make the repair, pull the LADBS permit, and hold the pressure test for the duration your inspector requires — then coordinate SoCalGas's return. Where a re-inspection is needed, that adds a day rather than a week.
I'm adding an ADU in Los Angeles. Will the existing gas line handle it?
Often not. A line sized for a 1930s house was never intended to carry a second kitchen, a dryer and a tankless heater on top of the original load. We calculate the demand for the finished configuration and upsize the run where it falls short — patching an undersized line simply moves the problem.
Can you repipe gas in an occupied apartment building?
Yes, and it is most of the multifamily work we do. Shared house meters and per-unit runs mean a single failure affects every tenant, so we sequence the work to keep units serviced and coordinate access with the owner or property manager rather than shutting the building down.
