EMERGENCY SERVICE AVAILABLE 24/7
We’re committed to providing excellent service at all times, and always work closely with you to ensure that your needs are met.
A failing gas line is not a repair you can put off until next week. The smell of sulfur near your meter, a hissing sound at a connection point, or a sudden spike in your gas bill all point to a leak that needs immediate attention from a licensed plumber. New Pro Plumbing handles gas line repair, replacement, leak detection, and new installation across Los Angeles, with the licensing, permits, and equipment to do the work safely and to code.
We service residential and commercial gas systems throughout Mar Vista, Cheviot Hills, Marina del Rey, Palms, Venice, Culver City, and the broader Westside. Same-day appointments are available, and we are reachable around the clock for active leaks.
When to Call a Plumber for Gas Line Repair
Natural gas piping is regulated work. In Los Angeles, every repair, replacement, or new gas line installation requires a permit and inspection through the Los Angeles Department of Building and Safety, and only a licensed contractor can legally pull that permit. Call us right away if you notice any of the following:
- Rotten egg or sulfur odor near appliances, the meter, or in the yard
- Hissing or whistling sounds at a gas line connection
- Dead or yellowing patches of grass above an underground gas line
- A gas bill that has climbed for no clear reason
- Pilot lights that will not stay lit on multiple appliances
- Physical symptoms like dizziness, headache, or fatigue that improve when you leave the house
If you suspect an active leak, leave the property, do not use any electrical switches or open flames, and call SoCalGas at 1-800-427-2200 before calling us. The U.S. Consumer Product Safety Commission provides additional guidance on recognizing gas and carbon monoxide hazards in the home.
Gas Line Services We Provide
Gas Line Repair
Most gas line failures in Los Angeles homes happen at threaded connections, at flexible appliance connectors, or at the point where the line transitions from underground to above grade. We pressure-test the system to isolate the leak, replace the damaged section with code-compliant black iron or CSST piping, and re-test before the gas is turned back on. Every repair is followed by a permitted inspection.
Gas Leak Detection
We carry combustible gas detectors and electronic leak locators that find leaks too small to smell. For underground lines, we use pressure decay testing and acoustic equipment to pinpoint the failure without trenching the entire route. The Pipeline and Hazardous Materials Safety Administration publishes federal pipeline safety standards we follow on every job.
Gas Line Installation
Adding a gas range, outdoor grill, pool heater, fire pit, or whole-house generator usually requires a new gas branch line. We size the line correctly for the appliance load, route it efficiently, install proper shutoffs at every connection point, and pull the permit through LADBS. New installations are pressure-tested and inspected before any appliance is connected.
Gas Line Replacement
Older Los Angeles homes often still have galvanized steel gas piping that has corroded from the inside. When a section fails, the rest of the system is usually close behind. We replace full runs of gas line with modern black iron or flexible CSST, including the meter riser, basement and attic runs, and underground laterals from the meter to the house.
Gas Pipe Repair for Underground Lines
Underground gas lines crack from soil movement, root pressure, and decades of corrosion. We locate the line with electronic tracing, excavate only what we need, and replace the damaged section with coated steel or polyethylene gas pipe rated for direct burial. For long runs under driveways or hardscape, we can sometimes use trenchless pipe lining techniques to avoid demolishing your property.
Emergency Gas Line Repair
Active leaks do not wait for business hours. We dispatch licensed plumbers for emergency gas line repair across Los Angeles, day or night, with fully stocked trucks and the equipment to make the system safe before completing the permanent repair.
Commercial Gas Line Repair
We handle commercial plumbing including restaurant gas lines for ranges and fryers, multi-unit residential gas systems, HOA properties, and retail buildings. Commercial gas work in Los Angeles often involves coordination with the health department, fire marshal, and SoCalGas, and we manage that paperwork on your behalf.
- Physical Health Symptoms: Since gas does not always smell strong, you will probably experience physical effects, such as fatigue, nausea, or dizziness, before you even notice a scent.
- Damaged Gas Appliances: If your gas appliances are making unusual sounds, such as a clanging, that could be a sign of a gas leak.
- Hissing sound: If you listen closely and hear a hissing sound from your gas lines, it means that there is a leak.
- Damaged Plants: If the household plants or flowers around your gas line area have started showing signs of decomposition, it’s an early sign that you need to call an expert for gas line repairs.
Common Causes of Gas Line Failure in Los Angeles Homes
The local building stock plays a role in how gas lines fail here. Many homes in Mar Vista, Cheviot Hills, and Palms were built between 1925 and 1965 with galvanized steel gas piping that is now well past its expected service life. Earthquakes loosen threaded connections over time. Slab foundations make underground gas lines harder to inspect. Older flexible appliance connectors corrode at the threads. Tree roots from decades-old landscaping push against shallow buried gas lines.
If your home is more than 40 years old and the gas piping has never been inspected or upgraded, a whole-system gas line inspection is a smart preventive step.
Warning Signs of an Underground Gas Line Problem
Underground leaks are harder to detect because the smell often dissipates before it reaches the house. We have a detailed guide on the warning signs of an underground gas line problem, but the short version is: if your landscaping has unexplained dead zones, your gas bill is rising without changes in usage, or you smell gas only when you are outside, get the line tested.

Why Homeowners Choose New Pro Plumbing for Gas Work
Gas work is not a job for unlicensed handymen or general remodelers. We are fully licensed, bonded, and insured, and we pull permits through LADBS on every gas line repair, replacement, and installation. Our trucks carry combustible gas detectors, pressure-testing equipment, and the full range of black iron, CSST, and polyethylene gas pipe needed to complete most repairs in a single visit.
We also provide written upfront pricing before any work begins, a workmanship warranty on every repair, and clear documentation of the permit and inspection so you have it on file when you sell the home.
Frequently Asked Questions About Gas Line Repair
How much does gas line repair cost in Los Angeles?
Most single-point repairs run between $300 and $850 depending on access and pipe material. Larger replacements, underground line work, or full system upgrades range from $1,500 to $5,000 or more. We provide a written estimate before any work begins.
How long does a gas line repair take?
Most repairs are completed in three to six hours, including the pressure test. Underground line work and full replacements may take one to two days. Permitting and inspection are scheduled on top of the repair time.
Do I need a permit to repair my gas line?
Yes. Los Angeles requires permits for all gas line repair, replacement, and installation work. We handle the permit and inspection process for you.
Can I smell gas if there is no leak?
Sometimes. Pilot lights and appliance connections can vent small amounts of mercaptan (the additive that gives natural gas its smell) without indicating a dangerous leak. If the odor is faint and goes away on its own, it may be normal. If it persists, gets stronger, or is concentrated in one area, treat it as a leak and call us.
Do you handle gas line repair on commercial properties?
Yes. We service restaurants, retail buildings, apartment complexes, and HOA properties throughout Los Angeles, including coordination with the health department and fire marshal when required.
What is CSST and is it safe?
Corrugated stainless steel tubing is a flexible, modern alternative to black iron pipe. It is code-approved, easier to route through finished spaces, and safe when properly bonded to the home’s grounding system. We install CSST when it is the right fit and bond it to current code.
