A&J Plumbing Company
Company Overview
We are specialists in every aspect of residential and commercial plumbing! We concentrate on tankless water heater installations and repiping services!
Arturo Cortez, a laborer who emigrated from Mexico to Southern California in the 1960s, founded our company. Art launched this family-owned business in 1991, calling it Mr. Plumber Company.
Following in Arturo's footsteps, Julio learned the trade from his father and later assumed control of the plumbing company. As the company expanded, Julio decided to rename and rebrand it.
As the CEO of A&J Plumbing Company, Julio has upheld a commitment to traditional, high-quality craftsmanship in the Orange County and Inland Empire regions for over ten years. He prioritizes exceptional service and ensures he is available to his clients. As a family-owned business with a deep-rooted history, we continue to offer families and businesses reliable, professional plumbing services.

Recommended Customer Reviews

A&J Plumbing is a great company. I have had them out several times and they always arrive on time and do an excellent job. Would highly recommend Julio!!

I called Julio at A&J Plumbing for a price quote on a pressure valve after getting a huge, overpriced quote from Flo Star Plumbing. First, while Flo Star took a month to finally keep an appointment, A&J came that same day and Julio quoted me 40% cheaper for the same work. He completed the job in less than 10 minutes and it's been functioning great ever since. Julio also took extra time to answer my other plumbing related questions.
I'll be using A&J Plumbing for all of my future plumbing needs.

Julio is an absolute beauty and installed a new garbage disposal for me. He and one of his employees were in and out in about 30 minutes. I called him because my 13 year old garbage disposal was leaking water. He called me back right away and said it's probably time for a new one, rather than repair; and I agreed. Julio told me that I had the choice of purchasing the new garbage disposal and he could install it or he could acquire a new garbage disposal on his end and install it. I opted to purchase my own at Costco. Once I received my new garbage disposal, I called Julio to set up an appointment for installation. Julio called me the next morning and said he could come later that day to install. He showed up a couple of hours later and removed the old garbage disposal (hauled it away too!) and installed the new one with ease. He was in and out within 30 minutes. Julio is very friendly, honest and professional. I cannot recommend him enough. Definitely reach out to him for your plumbing needs.

The worse company, Art Cortez took my money and didn't do the job. I decided to contact Julio Cortez, he was going to call me back and never did.

We were very impressed with the professional manner the Julio and his crew went about their business. Repiping our entire house seemed like a daunting task, but they were in and done in one day. Julio referee a drywall crew to finish the job and they also were done in one day. All and all, a messy job went well.

Julio is AWESOME!!!!! Not only is he extremely knowledgeable but he is also very honest and will do a great job at a good cost! He Goes above and beyond for his clients. Great company. I can't say enough about them!

A&J Plumbing is the best! I've used them for clearing drains, resolving clogged toilets, moving washer hookups and pipe behind walls, fixing leaks behind walls, installing sinks, and installing fixtures and drains.
Always professional, competent and courteous.

We've used A&J Plumbing on multiple occasions and the service has always been excellent. We have had some fairly complicated plumbing issues which Julio was able to resolve with no subsequent issues. He's very knowledgeable and reliable and honest to a fault. He's professional, courteous and cleans up after he's finished which we really appreciate. We would highly recommend A&J Plumbing. We've referred them to various friends and family members and the feedback on them has been consistently outstanding.

Once upon a time...I called this guy about some issues I had and on the phone he sounded very knowledgeable and experienced but when he showed up with his barely visible mustache I thought I'd been duped. Turns out this kid was able to repair the issues in less time AND less money then originally quoted.
I will definitely be testing his skills in the future!

I can't recommend a&j enough! I contacted Julio in regards to installing some new faucets. He was quick to respond, professional and did an amazing job. He was very detailed in explaining what he was doing. His pricing is very reasonable and I would trust him with any plumbing issues you have. I already have him coming back to fix my toilet!
