I am Raymond Gray, and plumbing runs in my family for generations. For many years, my great-grandfather and grandfather worked as pipe fitters on military ships. In the 1960s, my grandfather transitioned to the Union after his Navy service. Eventually, he specialized in residential and commercial plumbing services and repairs.
My father, born in 1961, learned plumbing from my grandfather during his childhood. In 1977, I was born, and I vividly remember crawling under houses at eight, playing in the dirt, and watching my dad fix things. 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. In 2001, I started working alongside my dad once more. 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.
My family has a long history in plumbing that I can recall. I bring over 30 years of plumbing experience, with 20 years focused on underground trenchless, CIPP, and pipe coating. I work with sewer, water, gas, air ducting, culverts, and various other plumbing tasks.
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

A1 Total Service has been my plumbing choice for the last 10 years. Once again they went the extra mile to locate the parts that I needed for the job and then work with my schedule and that of my tenants to make it happen.
They have always been courteous and concise with professional invoices and estimates. Their prices are reasonable and They've never tried to take advantage or inflate the price.
From my technician Dave Diaz, the managing director Alex, Aubrey on the phones, all the way up to the owner Raymond, I recommend these folks because they take good and careful care without dropping the ball on large or small jobs.
And I, in my older years now appreciate a peace of mind they give me that the job is in good hands.

I've used A1 for about 5-6 years now, doing periodic jetting of my main line. The technicians are knowledgeable and friendly.
I've used other plumbers and A1 has always been the most trustworthy.
HIGHLY RECOMMENDED!

Had a leak coming through my kitchen ceiling from the 2nd floor on a Sunday. Called them up and they were here within 45 min. Took the time to diagnose the issue, going through several steps to determine the source of the leak (upstairs toilet drain) before finalizing an estimate. Did a good job of controlling the leak and coming back Monday morning to complete the repairs before lunch time.

David did a great job installing a new hot water heater. I would highly recommend A-1 Total Service plumbing for all your plumbing needs. I have used them multiple times and they are my go to plumbing company.

This review is specifically for John the plumber. He was not only patient and hard-working, but also extremely friendly. We could not have had a better plumbing experience than the one we had with him. He is fully transparent and does not scam customers like many others who are after a quick buck. His work is noteworthy! THANK YOU AGAIN!

We had a leak in the master bath sink and Jose from A-1 Plumbing came over the very same day and installed new faucets and fixed the leak! The price was incredibly reasonable. He stayed late to get the job done right and even followed up a few days later to make sure we were happy with the install. He was polite, efficient and very nice and on time. We totally recommend Jose and A-1 Plumbing.

Jose came for the tankless water heater maintenance with mask on. He showed me how dirty the unit was and explained to me that the frequent error code 12 shown on the panel was due to too much debris clogged up the unit. He helped me clean up the unit and replaced the new cartridge for the filter. I really appreciate his professional work.

Jose saved the day!
A hose in our bathroom broke, so we had to turn off our water main... on a 90 degree Saturday... during a pandemic... with a toddler. I called in, and the dispatcher was helpful and easy to communicate with. Within an hour, Jose was at our door.
He gave me a quick breakdown of what needed to be fixed and what it would cost, and then he got right to work. Everything was fixed within the next hour, and now my toilet is good as new.
I love how easy it all was. I had called around for any plumber in the neighborhood, but since it was a weekend, I ended up leaving a lot of voicemails. A-1 answered right away, let me know when Jose was near, and got the job done. Thank you!

I recently had a plumbing problem at my income property. The tenant reported that water was not going to the shower head. I called A-1 Plumbing Const., a company I have used before. They sent someone to check the situation out immediately. They advised that the part needed to repair the shower is no longer being made. This is a house that is 100 years old. They advised that I needed to replace the shower assembly. I OK'd the work without having to visit the site. I have been doing business with this company for several years. The tenant is pleased with the work, I am pleased with the company and will continue to use them. The workers are kind, courteous and professional.

These guys were super courteous and nice. They were the third plumbers called out to try to figure out why sludge kept coming up through my bathroom drain and they were the first to be able to diagnose the problem. Highly recommend.
