Founded in 1998, SJ Plumbing is a family-run business. The current owner is a second-generation plumber who has been involved in all facets of plumbing from a young age. After his father's death in 2011, the business was re-established. Since then, he has kept his father's memory alive by servicing homes, dining establishments, schools, and various private facilities in Orange County and adjacent areas.
John was born and raised in Orange County, where he began his journey with a wrench. Plumbing has been his passion since his teenage years, and he remembers the times his father would invite him to help tighten bolts or turn off the water valve for new home improvement projects. This often meant it was time to dig or work through walls, where he discovered his talent for repiping. As a second-generation plumber, John re-established the business in 2011 after his father faced an incurable illness and lost his fight against cancer. There is no plumbing task he cannot handle. With his team, whom he treats as family, they are all well-prepared and knowledgeable to get the task accomplished.

Recommended Customer Reviews

SJ Plumbing was a great help!! Lifesavers.
They had Sal come out to find & fix a leak that was causing a headache.
Sal was quick to find the leak and to come up with a solution. Sal was very explanatory to what each step was happening and what was to come next, he answered all and any questions i had. He took the time to make sure I was happy. Thank you SJ & Sal! We'll definitely refer.

John and his crew are reliable, friendly and very fair. I am very satisfied with his professionalism and care. Thank you so much.

John and the SJ team provided superb customer service. Water was leaking out of the side of my house, I thought it was a leaking sewer line. Ryan and Sal were onsite next day for a camera inspection and determined no leak in the sewer line, so John came out personally and determined there was a water line leak somewhere in the house. Tim and Dylan came over the next day and did a very thorough leak inspection and found the leak was in the hot water line under the concrete slab in my family room. I feared we might need to jackhammer the floor, but Tim provided 3 good alternative options, and I chose the least invasive. Tim expertly made the repair without the need for any damage to my floors or foundation. The SJ team was prompt and provided great communication. I would highly recommend.

Oh, clutch your pearls already. I said the word sh*t! If you would have acted professionally and called me instead of ignoring the fact that you were going to be 45mins. late, I wouldn't have been pissed enough to say that in the first place.

John fixed an outdoor faucet for us. Quote was very reasonable. They were prompt on arrival and completed the job as expected. Appreciated they cleaned up afterwards. He also had to do extra work that was not in quote and he didn't add any additional cost. Will definitely use SJ again.

Our technician Daniel was prompt, courteous, efficient, friendly & clean. Highly recommend this company.

For the record, I only write reviews when I am severely disappointed or extremely satisfied. Thankfully this review is the latter. I needed a gas valve replaced ASAP and SJ PLUMBING was able to send a technician out the same day (Friday afternoon). Tim Torrez showed up right on schedule and was able to quickly perform the work. Not only was the work done professionally, Tim was polite, efficient and even gave me a solid quote for a water heater replacement. I highly recommend SJ PLUMBING.

Needed a very last minute repair due to a leaking faucet. Responds quickly and gives a fair competitive rate! Would definately recommend :)

We initially contacted a different plumber to diagnose our system because the water pressure gauge by our tankless water heater was displaying a PSI higher than safe levels. The plumber attached his water PSI gauge to our hose spigot but received no reading. Apparently, his gauge was broken, and he even admitted it. However, he still recommended we replace our pressure regulator valve at a quote of $930, even without a functioning water PSI gauge! I told him I'd shop around.
I contacted SJ Plumbing and John, the owner, was polite and responded quickly. David came to our home and had a working water PSI gauge which he attached to our hose spigot. The reading was 60 PSI, which is considered normal, so it was actually the water PSI gauge by the water heater that was faulty. The pressure regulator valve was functioning properly, and they recommended no replacement, so we ended up saving hundreds of dollars. We'll be contacting SJ Plumbing in the future because they are honest and professional.

Response time was very fast. Able to fix our issue quickly! Daniel was awesome! We will definitely refer to our friends and family!
