    Amazing job upgrading our data center

    These guys are Amazing!! We received an estimate from them for a big commercial job. I have to admit I was skeptical at first from looking at them online and noticing that the company wasn't as big as some of the vendors we normally use but since they were referred by a trust friend we gave them a shot. So glad I did! Kevin came out gave me a bid on the job and the price was too good to be true. However when it came to the service I was blown away, the knowledge they had was astonishing! We had other bids that were extremely high and J&M not only beat the price but did it in a timely manner with a great service and positive attitude! No matter if the job is big or small these guys are the ones to call!

    Mission light.

    Have been wanting to work with this company but no responses to questions and no one there when I call. Surprised with their 5 star rating.

One tip -- Matthew is a one-man operation so give him a day or two to respond to calls. He's worth the wait!

So I chose a company that actually earned its reputation! Matthew checked all the boxes! His prices are reasonable, and he's a down-to-earth guy to work with! Yes, I've seen the other reviews where the only complaint is his response time but honestly patience is a virtue! You have to keep in mind that this is a small company and when customers are calling him for an estimate, he's most likely under the sink working . It's not always so easy to be a receptionist and a plumber at the same time! He's a small family owned businesses and definitely takes pride in his work and it shows! We definitely will be working with him again down the road and will pass on his name to others in need! Thanks, Matthew. It was a pleasure working with you.

    Highly Recommended - Jonathan exceeded expectations!…read moreJonathan is a licensed, insured, and fully certified contractor with the City of Los Angeles. I hired him for a commercial project in Los Angeles that required a licensed, bonded professional with City certification to pull the permit. He handled the entire permitting process smoothly, completed the work efficiently, and passed all inspections without any issues. Jonathan is highly experienced, always on time, extremely responsive, and a true professional. Best of all, his pricing was very reasonable -- significantly lower than some unlicensed and uninsured contractors I had quoted. I highly recommend Jonathan for any plumbing or commercial project in LA or OC . You can trust him completely.

Jonathan, the owner, happened to be in the area and was able to stop by the same day to look at the project. He was easy to talk to--friendly, professional, neat, and clearly very knowledgeable in his craft. He made a couple of great suggestions I hadn't even considered, which really set him apart from the other plumbers I spoke with. Unfortunately, our laundry room tested positive for asbestos, so the project is currently on hold until that issue is resolved. What also impressed me was Jonathan's professionalism. There was no pressure to hire him, and his pricing was very reasonable--his quote was actually the most affordable among all the plumbers I contacted, nearly half the price of some others. That said, Jonathan of Mr. J's Plumbing is definitely on my go-to list for plumbing work. Highly recommended!

    Wow, where do I even begin? I am absolutely blown away by the level of service and care I received…read morefrom Drain Brothers. My kitchen sink backed up, and it turned out there were roots about 2 to 3 feet down the line. One plumber wanted to just run a high-speed chain through it, clear it out, and call it a day. Another said they could not even look at it for a few weeks. I was stuck. In desperation, I called my realtor, who recommended Drain Brothers. They came out the very next day. Ozzy assessed the situation and immediately explained that I needed a cleanout installed because my house was built without one. Having grown up with a father who was a contractor, and spending my summers working construction and plumbing with him, I knew Ozzy was right. I also knew this was not going to be a small job. They would have to cut open the back of the house, cut into the plumbing, and repipe it to install the cleanout. To my surprise, Ozzy said, "We can do it right now." LFG!!! Once they accessed the main line, they found exactly what I expected. Roots had breached the pipe a few feet down. Fixing it meant jackhammering concrete and tunneling under the house to reach the damaged section. This is not a quick or easy task. Again, Ozzy did not hesitate. He said they would take care of it that day. Unreal! I gave them the green light, and they got straight to work. It turned out to be even more involved than expected, but Ozzy and his crew kept pushing. They worked until almost 10PM. It was in the 30s outside, and not once did they complain. At one point, I told them they could head home and come back the next day. I would have completely understood. Ozzy looked at me and said, "We are getting this done for you today." That kind of work ethic is rare. I cannot say enough about Ozzy and the team at Drain Brothers. Professional. Honest. Hard-working. All around great guys. They did the job the right way, not the quick way, and they stood behind their work. If you want it done correctly and you want people who genuinely care, call Drain Brothers. I would HIGHLY recommend them to anyone without hesitation.
