Signs of a gas leak

Rotten-egg / sulfur smell

Hissing near a line, appliance, or meter

Dead or discolored plants over a buried line

Higher gas bills with no change in use

Dizziness/nausea that improves when you leave the house

Unexplained appliance performance changes

If you notice these: leave, call SoCalGas, then us.

Why licensing matters here

Anyone can call themselves a handyman; gas work legally requires a licensed contractor — and doing it wrong risks your family’s safety and your insurance coverage. We’re licensed CA #1067555 (verify at cslb.ca.gov); we pull permits, and every gas job is pressure-tested and inspected. That’s not a formality — it’s how you know it’s safe.

Frank with Advantage Plumbing is really excellent. He’s been out to our house in South Pasadena a few times. He’s always on time, can come on short notice when needed, and is super professional and capable. Always gets things fixed quickly at a fair and reasonable rate. He’s also a super nice guy. Always asks about our dog, for example, who’s been having medical issues lately! Class act.

Frank (the plumber) did a great job installing our tankless water heater. It was a tough job under the blazing heat conditions.

We've hired Advantage Plumbers for three jobs so far and are very happy with their work. Their prices are reasonable and the plumbers go out of their way to make sure the job is done right. They make suggestions when needed which is helpful and even pick up parts when necessary. We would especially like to acknowledge Victor and his assistant for fixing the leak in our outdoor pipes.

Great company. Called them for a leak under kitchen sink (cat stood on pipe and the weight separated the connections). They offered to send someone same-day, but I opted for next morning instead. I love that they use a one hour appointment window, instead of 3-5 hours like other companies. Technician, Victor, arrived right on time, explained the issue to me and pointed out a couple other problems, fixed everything and tested everything thoroughly before leaving. I told him about the cat and he made sure to "cat proof" the connections. Like I said, great company, don't hesitate to use them.

Frank has done work at my properties for ages. He's always been congenial, forthright, and honest with me, even erring on the side of caution when necessary because he knows that doing a job right is the utmost importance.

We had Advantage plumber Frank come over to flush our tankless hot water system. He was very efficient, friendly and got everything done and operating- no fuss- no muss- so nice to have hot water. Thanks Frank!

Advantage Plumbing repiped my entire crawl space, including the main line under my house and the lateral line in my front yard, this past week. I interviewed six companies before choosing them, and from the first visit through project completion, the experience was exceptional. They gave me a fair, respectable quote, and the work was fully permitted (Advantage pulled the permit at a modest cost). Even the city inspector said, "Nice work!" The crew was punctual, courteous, hardworking, and clearly knowledgeable — top-notch in every way. For the front yard line, they used pipe-bursting technology, so my yard didn't need to be dug up. The new line will last 100 years. Every part of the job — proper strapping, quality materials, multiple cleanouts — was done to the highest standard. This was truly exceptional work, and I'm grateful for their dedication. Thank you to Steve, Johny, and the entire crew for a job so well done! Separately, before the repiping project, I had Advantage come out to snake a clogged tub drain. They arrived the same day and did a great job. Alfonso and Jose were punctual, kind, friendly, and attentive — another job well done!

There are simply not enough complements I can give this team. I had a water dripping on the street issue that ai could not figure out . When soap bubbles appeared, we realize the problem was the sewer . Steve rearranged his team schedule to get the problem fixed and fast. The pipe, on a hillside was scoped with a camera revealing the severity of the 90 year old cast iron pipes. A replacement was needed. One can only shudder to think the cost of that. Using new technology called pipe lining, not only was the pipe repaired from the inside out , they even managed to clean the pipe below the street, saving us thousands of dollars!! . They even found a fresh water leak and were able to repair it while the pipe was exposed. The entire job was done in a day. I simply cannot sing high enough praises for Steve and his team. Professional, caring, on time with a fanatic work ethic. Steve truly cares about people and not just money . Look no further when needing help with an unpleasant issue of plumbing. UPDATE: Had another leaking pipe problem. . Advantage sent Plummer Frank whose long experience in the field, quickly and easily fixed the problem. Thank you!

Victor with Advantage Plumbing & Rooter was fantastic to work with. He quickly solved our water pressure issue, took the time to listen to our longer-term plumbing goals, and scheduled a follow-up to address everything else we need. We were thoroughly impressed by his expertise. Highly recommend!

Advantage Plumbing helped me out tremendously. Their guy Frank is great. I had an upstairs leak in a wall that he investigated and found the location of quickly without damaging too much of my wall. I would highly recommend this company.

I’m so glad we went with Advantage Plumbing for our water heater replacement. I expected the process to be a bit of a headache, but they made it surprisingly easy. They showed up right on time, were friendly and respectful, and completed the job without any unnecessary complications. The new water heater was installed efficiently, and everything was cleaned up and left in order. I really appreciated how easy they were to work with. I’d happily recommend Advantage Plumbing to friends and family and would definitely call them again.
