I am Raymond Gray, and plumbing runs in my family for generations. My great-grandfather and grandfather were pipe fitters who worked on military vessels for many years. My grandfather joined the Union after serving in the Navy during the 1960s. He later focused on residential and commercial plumbing service and repairs.
My father was born in 1961, and my grandfather instilled plumbing knowledge in him from a young age. 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. While I didn’t enjoy plumbing at first, my upbringing in a struggling family compelled me to acquire a trade.
After dropping out of high school, I got my GED and set out on my own. I rejoined my dad in the plumbing business in 2001. I launched A-1 Total Service Plumbing in 2004 and have never regretted it. I collaborate with my dad daily. I demand excellence from my plumbers so I can provide top-quality service to my clients.
Plumbing has been in my family for generations. I bring over 30 years of plumbing experience, with 20 years focused on underground trenchless, CIPP, and pipe coating. I manage sewer, water, gas, air ducting, culverts, and additional plumbing services.
I hold all my service technicians to high standards of quality service, ensuring they align with our company’s core values. Our commitment to service and honesty is the reason the A-1 team boasts an 85% customer retention rate.

Recommended Customer Reviews

A1 Total Plumbing was very professional and attentive , as well as instructions on the unit we had installed.
Thank You,
Jose and jessie

Dave Diaz from A1 came out to my house yesterday to take a look at what I thought would be an easy external clean-out for my upstairs master sink that has been slow to drain lately. That being said, the job became more complicated than expected. Long story short, we decided to wait on the project until Covid cases subside a bit down the road (we were trying to keep people from entering our house). Dave was extremely courteous, knowledgable, and didn't charge a thing even though he spent about an hour of his time at the house. I'll definitely be reaching back out to Dave and A1 for future plumbing needs!

The best service man very kind friendly and informative a huge thank you too Dave Diaz love the smile behind the mask stay safe
Thank you Gloria Farfan

Mr. John Gray came to our Redondo Beach house to fix our toilet & tank leak and he did an amazing job. We highly recommend him. Thanks very much - Judith

I experienced my worst nightmare last month with sewer plumbing issues. This became a large job with a very high dollar amount attached to it. I was scared, unsure how to find the right company that would not rip me off, Unsure of the process and thought one more 2020 nightmare. However, After calling several plumbing companies I landed upon A1 total service plumbing. I am thankful that I did. My technician was David Diaz, a kind and thoughtful young man which meant the world of difference. My project ended up taking three days to complete however they took their time and did it right. I am recommending this company because I feel like the customer support, response time and ability to solve the problem was outstanding. I hope no one else has to go through a costly repair situation similar to what I did, however if you're needing professionals, David and A1 is the service I recommend.

We had a serious plumbing issue that needed immediate attention. We called and they came over promptly to see what the problem was. We worked with Esteban and David Gutierrez and they worked diligently to resolve the issue. They fixed everything and were very modest and professional! Would definitely recommend not only A1 but also these two gentlemen to help with any of your plumbing issues.

I called A1 for a commercial property- needed a waterline installed from the 2nd floor out to the roof. David Diaz and his crew came out, got the job done! very neat, didn't leave anything behind. The crew was respectful of the employees. They sent pictures/ video of the job once it was completed and pricing was the best out of 5 estimates.
Good job guys! we will be using A1 for all our plumbing needs!

George and Jesse came quickly took care of the stoppage and were so nice and informative i so appreciated them and Jesse also fixed a piping for me these two gentlemen were a godsend and I will have no problem ever recommending them my nsmr is ssndra conrad

A-1 overcharges so watch yourself. They are quick to respond and leave things clean but very pricey. They charged $750 to repair a easy access pipe that took less than 30minutes. They will gouge you and make things appear more urgent than they really are to get you to approve repair. I would not use them again.

This review is long overdue. I live in an old house, and I had four major sewage backups within a year (this has been a continual issue but got worse over the last year). The latest backup occurred late on a Saturday night, and A1 was the only plumber who was willing to come out and didn't charge a ridiculous amount to do so. George, the lead plumber snaked my main, then found an additional clog none of the previous plumbers checked for. They also offered as part of the cost to run a camera to show my problem areas a few days later.
Well, that day came, and they found:
* clay pipe that had never been replaced
* fix deteriorating cast iron kitchen line that no one else had been able to access without having to tear apart my foundation (don't ask).
They fixed the kitchen line by descaling it and then running this sleeve through the damaged pipe, effectively turning it into a new pipe. And they replaced that pesky clay pipe with the proper ABS.
It wasn't cheap, but it was a fraction of what it would have been even a few years ago. Everybody on the team, particularly Marios Sr and Jr always kept me in the loop and were super helpful. This is the first time I've ever felt confident about my plumbing in the more than 20 years I have lived in my house!
So, I recommend them highly and am thankful that chance and desperation sent me their way. Special props to Alex for coordinating everything.
