I, Raymond Gray, come from a long lineage of plumbers. For many years, my great-grandfather and grandfather worked as pipe fitters on military ships. My grandfather joined the Union after serving in the Navy during the 1960s. Eventually, he specialized in residential and commercial plumbing services and repairs.
My father, born in 1961, learned plumbing from my grandfather during his childhood. I was born in 1977 and recall crawling under houses at age eight, playing in the dirt while watching my dad make repairs. I started tackling repairs when I was about twelve years old. I wasn’t fond of plumbing initially, but coming from a financially challenged family motivated me to learn the 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 founded A-1 Total Service Plumbing in 2004 and have never looked back. I work with my dad every day. I expect the best from my plumbers to ensure I deliver the best to my customers.
My family has a long history in plumbing that I can recall. 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 require all my service techs to provide excellent service while following our company’s core principles. The A-1 team’s dedication to service and integrity is why we maintain an 85% customer retention rate.

Recommended Customer Reviews

I was having a party for Labor Day and my kitchen sink started clogging up. I called A1 and they sent Edgar out in a few short hours! He opens up the drain and released all of the gunk and oil and he even cleaned the concrete with a water hose, to be sure there was no residue left over. Amazing service, amazing prices, amazing company!

They got here within 30 minutes, fixed my pipes so fast , got everything cleared out within a hour!
Great price too.
I will forsure call A1 total service plumbing if I ever need plumbing service again, highly recommended :)

Techs were friendly and knowledgeable. Will hire again if I need plumbing service in the future.

My experience with A1TSP was outstanding. I have (maybe should say had) my regular plumber but decided to get a 2nd opinion & glad I did. These guys are top notch. Edgar was absolutely great & pleasant to deal with. He was honest & very knowledgeable bout the task at hand. Best thing is these guys like getting the job done right the first time. Their dispatchers were really nice & helpful. Overall a wonderful experience, I'd definitely recommend them, & will be using their services again.

I have a household of 8 and our toilet was backed up I googled plumbers near me and found this place Guillermo was here within a couple hours and he worked hard to clear the clog but it was too far out. He was here first thing the next morning on his day off with his boss they sent the camera down found the problem and Guillermo stood here until he cleared the pipe and made sure my household was good to go. So grateful to him and thankful. Highly recommend this place

Alex and Jose were amazing. I had a plumbing crisis during covid and they were so responsive and professional. I recommend them highly

These guys are really professional. I called them in an emergency situation when my normal plumber wouldn't answer. They came immediately, diagnosed the situation, and gave me a few options. The next morning they changed some leaking galvanized pipes with copper piping and related parts. They did a very good job, they were clean, and they were courteous to my tenants. The finished work looks like it will last 100 years.
Thank you to Esteban and Edgar, the plumbers that did the work!

They showed up to fix my disposal within an hour of calling! Esteban Gutierrez was my technician and he was friendly, fast and EFFECTIVE. I'd recommend them to anyone!

A1 Total Service Pluming has been quick and efficient. I spoke to Alex on the phone regarding an issue I was having with my tankless water heater and he told me that it could be due to filtration service that needs to be flushed and filter that needs to be changed out. Alex was very courteous and explanatory over the phone. The next day, he had Jose sent out to check on the issue. Jose was very detailed and explained everything in detail of what was going on with my water heater. He fixed the problem and flushed the system. Everything works great now! Highly recommend their fast, reliable and detailed service.

Guillermo at Total Service Plumbing was wonderful in servicing our clogged drains. He came immediately when we called and didn't even charge us when we asked that he come back. We love the service and highly recommend A1 Total Service Plumbing.
