My name is Raymond Gray, and I hail from a family deeply rooted in plumbing. My great-grandfather and grandfather were pipe fitters who worked on military vessels for many years. In the 1960s, my grandfather transitioned to the Union after his Navy service. He eventually moved into residential and commercial service and repair.
My father, born in 1961, learned plumbing from my grandfather during his childhood. I came into the world in 1977 and remember, at eight years old, crawling beneath homes, playing in the dirt, and observing my dad perform repairs. I started tackling repairs when I was about twelve years old. Though I initially disliked plumbing, growing up in a low-income family pushed me to learn a trade.
I dropped out of high school, earned my GED, and left home. In 2001, I began working with my dad again. I founded A-1 Total Service Plumbing in 2004 and have never looked back. I work with my dad every day. I demand excellence from my plumbers so I can provide top-quality service to my clients.
Plumbing has been a part of my family for as long as I can remember. With more than 30 years in plumbing, I have 20 years of expertise in specialty underground trenchless, CIPP, and pipe coating. I handle sewer, water, gas, air ducting, culverts, and more.
I hold all my service technicians to high standards of quality service, ensuring they align with our company’s core values. Service and honesty to our customers are why the A-1 team enjoys an 85% customer retention rate.

Recommended Customer Reviews

In April 2023, we had a gas leak. We called A1 to fix our gas line. It took them three days to fix what should have been a simple leak.
Two days later, we started experiencing issues with our toilets. We called A1. Technician came out and said that the issue was not related to the repair of the gas line; that likely the issue had been there a while and our pipes were backed up and needed to be flushed out. He snaked the drain.
We continued to have plumbing issues and called a third party who came out and scoped the sewer. As it turned out, when putting in a new gas line, the A1 tech skewered our sewer line, and that was the cause of the issue.
Two days ago, we discovered another gas leak. We contacted the gas company and they came out Monday evening, determined we had a leak, turned off our gas. We contacted A1 to come out, as we have a ten year warranty on the parts and labor from their work. The initial tech they sent, Jose, said there was no gas leak at all. We called a a 3rd party plumber; he came out and and said there was a ""massive"" leak. We called A1 again; they attempted to send the same tech out. We said no, we need a more experienced tech. Admittedly, I was extremely frustrated and raised my voice when I called back - the dispatcher proceeded to hang up on me.
The manager called me back and apologized. I sent him evidence from the 3rd party plumber, and they send another technician out. After three hours, Guillermo (who was great) fixed not one, but two leaks. He said one happened to be massive. We called then called the gas company to come out and turn our gas back on. The gas company then found an issue with the earthquake valve (which had no issues before). I called A1 again - regardless of the issues I had, they said that particular part wasn't under warranty and they would give me no break on pricing for the replacement and labor.
This is all while wildfires are raging through LA, and could have caused a massive explosion.
Two days in, we still do not have hot water and heat. It was 48 degrees in LA last night.

A1 has a very professional team! Danny came out today and did a thorough review of our situation. I especially appreciate how clear he was about his process. I always knew what to expect from each step.

Jackie Vasquez was amazing! He was efficient & professional. He came out right away and knew exactly what the problem was and what was causing the repeated blockage. I would definitely use A-1 again.

We have used A-1 Total Service Plumbing in the past and have always been very pleased with their receptionists, plumbers and services. They are professional and knowledgeable. Their communication is exceptional. They send pictures and explanations of their service. Today we had plumber Jose Ruiz Cendejas. He did a wonderful job!

I got my garbage disposal replaced. The service was great! They were very reasonable in cost as well. They also offered to look at the rest of the house at no cost. I was really satisfied with my experience. Thank you A-1 Total Service Plumbing!

Melvin is the real deal. This guy is our GO TO. If you want something done right, he's the man to get it done.

Knowledgeable service providers. Great service! I recommend A-1 Total Service Plumbing.

Alex and Vahn were great and super helpful and knowledgeable. They unclogged my sink in record time, answered all my questions and setup a future appointment for maintenance. Wonderful to work with and highly recommend. Nikki in administration helped coordinate the schedule as well and was able to get a technician out same day, and was super in contact the whole time and helpful. Thanks A1!

I've worked with this company a couple times for various repairs and help on the house - each time they go above and beyond. Esteban Muniz is respectful, efficient, and thorough. Repeat client for a reason.

Fast service. Knowledgeable. Friendly. What more can you ask for? Great work. I'd definitely call them again.
