David was on time and incredibly knowledgable. We needed a water filter change and the filter was stuck. He was able to give a quick assessment, clean out and change out the filter efficiently! He also inspected all things related to our tankless water heater and gave me his honest insight. We will be contacting David again for our plumbing needs. read more

Came same day and helped fix the drain line coming out of our washer. Will use them again. Thanks David!

I have kept using David for years now, at home and at the office -- still first rate in my book.

There are three things I look for in a service provider 1. quick to provide assistance when needed, 2. able to accurately diagnose and remedy the issue at hand and 3. is honest and fair with their pricing. David from Mulhearn Plumbing checks all those boxes and then some! We had some issues come up in a few parts in our home and David quickly came the same morning to get us back to working order again I appreciated that he didn't try to up sell us, or guilt me into more work than we could afford at this moment. Even when the task at hand ended up being more than expected, he was still thorough and made sure the work he did would last for a long time. (and boy was there a lot of unexpected extra stuff) If you live in the Cerritos area, this is the plumber for you! read more

If I could rate Dave and his associate a 10 it would still not be enough! He arrived on time with the necessary supplies and equipment for what I considered a major job. He completed the requested project quickly and efficiently. In the process found other work that should be done and thoroughly explained a potential problem which we went ahead and authorized the work. After all the work was done they cleaned up better than when the work was started. Dave is very personable, quick to respond to our initial call and a top notch experienced professional. We are very fortunate to have found Mulhearn Plumbing and will be a life long customer. Thank you very much for a perfect experience. read more

Just had David out today to install a new gas line to my kitchen. 5 stars plus! He was on time, organized and super efficient. You can tell he has the experience and knows what he's doing. Such a great guy he even helped me carry out the old stove and bring in the new one, hooked up the gas to it and made sure everything was working. Resetting the pilot on my old water heater was a little difficult given it's design but again using his experience he got it going no problem. He will be my go to plumber going forward. I just hope he doesn't retire anytime soon! read more

This is very overdue. Our toilet needed to be replaced. David came and replaced the toilet, which also solved the sewer problem that we've been battling for several years. He explained that the toilet was incorrectly installed. He came back later to install the bidet unit for free. Very professional and capable. I would, and did, definitely recommend. read more

Our second bathroom sprung a leak. Water saturated the downstairs ceiling and began dripping on floor below. OUCH!! Needed a plumber FAST. Yelpers suggested Mulhearn Plumbing. Dave answered and came out right away. He found the leak pronto and fixed it. The next day I still saw water on the bathroom floor. Called him again. He came right away with a female apprentice. She helped him with a few preliminary tests. Again he found the problem right way . . . water from the shower head was leaking into the walls through a loose faucet. Just needed caulking, which I did myself. All's well again. read more

David was great. We called him last week and he advised us to reach out to Kohler to replace a faulty Hydrorail shower cartridge as it would be covered under warranty. He was right. We received the part yesterday and called him today--he came out promptly, finished the job quickly, and was sure to keep his distance. My wife was particularly pleased that he respected her ask of wearing "booties" over his work boots and dutifully putting them on/removing them each and every time he entered/left the house without complaint. Have recommended him to family and will recommend to nearby neighbors and friends. read more

I reached out to Mulhearn plumbing after doing a bunch of research and comparing the rates for other services and I have to say hands down David at Mulhearn Plumbing was just amazingly fast, efficient, and very reasonal rates.

Thank you so much David!! read more

I had a great experience with Mulhearn. David was quick to reply and diagnose my issue. He gave his thoughts on the potential problem and referred me to a potential solution. Although we did not end up needing service after all, it was Mulhearn who was professional, knowledgeable, and authentic in giving me sound advice that was in my best interest.

He replaced and installed a new tankless water heater and even cleaned up the clogged drain because the water from our washing was backing up. We will keep using your services David!! read more

My kitchen sink was clogged up and I had been unable to unclog it myself with a 25 foot snake. I called David and he quoted me a price to unclog my sink. Well this clog was one of those stubborn clogs which required that David attempt a few different methods to unclog it. At one point he had to climb on top of my roof to attempt to unclog through a vent. Eventually David was successful in unclogging the sink but it took much longer than he had anticipated. Many plumbers would have given up or attempted to charge more than what they had initially quoted because of the extra work and time which was required. I was really pleased when David charged me the agreed upon amount. I must say that David is honest, knowledgeable and extremely professional. He was diligent and made sure he completed the job the right way. I will be using Mulhearn Plumbing for my future plumbing needs. read more

David, I believe was his name, was responsive when called and was immediately available to stop by when asked for availability. He said 4p and arrived around 3:40p. He quickly diagnosed and solved our issue with the clogged drains. His equipment looks up to date, cleaned, and he removed 2 feet of root from our mainline. Haven't used a plumber before so can't comment on value or price. The service was great, friendly, and professional. He made sure to clean up any mess that was a result from the work done. Overall, would definitely recommend. read more

Excellent service! Fast, reliable, responsive and honest. Very glad to have come across his services and will be calling again with future business. read more

This is going to be an odd review The first time I called Mulhearn, they quickly and efficiently came by and gave me a quote. While I went a cheaper route (pvc), I still appreciated his quick response and advise The second time I called, it was for a water leak emergency. When I got home, I found out it was for an overflowing toilet and a plumber was not needed. I immediately called Mulhearn back to cancel the call. They were already leaving for my call, so they canceled the visit Both times that I called, they were prompt, courteous, and understanding While I never actually paid for their service, I will definitely do so once another opportunity comes up read more

I called Mulhearn and David came down immediately, initially I thought he was quoting high, but when he saw my sump pump, which was not working, he fixed it and solved the issue by not replacing the motor which other plumbers were planning on doing it, David saved lot of money and suggested other better things to do.... Definitely recommend this person for future plumbing issues.... read more

I called Mulhearn Plumbing to fix a plumbing problem. He came out right away, gave me a quote and went to work. He was very honest, the price was reasonable and found the problem right away and fixed it. The problem was from the prior plumber (not hired by me as this was a new home purchase) who fixed a plumbing issue and left a rag in the pipe before sealing the pipe. The plumber who did that, would not even come out and see why the plumbing stopped working after he "fixed" it. This is why you need a plumber you can trust like Mr. Mulhearn. read more

David Mulhearn is a good and honest plumber. His work is good. He responds quickly. His prices are reasonable. Don't let his quiet demeanor make you think he's not good. He knows what he's doing, but will also happily work with you to give you what you want/need and all to pass inspection/code. What did he do for us? - reposition and reinforce 2 hose bibs - repipe some kitchen faucets valves which were seeping from bad solders, and just laid out in an awkward way in the cabinet by our remodeling contractor - install an inline vent per city inspector's requirements - install a new drain pipe from our water heater to the outside of the house, per code Some stuff may take longer than expected, but David sticks to his bid. In one case, something was easier than expected, so he took to the total down after everything was done. read more

If you need plumbing service from an honest and local plumber, I would highly recommend Mulhearn Plumbing. I called just to scheduled a appointment and he had someone arrive at my home less than an hour later. David Mulhearn arrived early and is extremely professional. All the issues were addressed along with a few recommendations in an efficient manner. The cost of service is reasonable and I appreciated his diligence. Not only did he fix the toilets that my children damn/clog to heck with the girth of their "waste" and fix temperature issue with one of the showers that has been lingering. But did it with genuine enthusiasm for his work and wanting me to be informed of what was being done and did not push any unnecessary work. This type of experience is why I prefer to support local and small businesses. read more

I own a restaurant and when something fails we need it taken care of quickly. This morning, 20 min. before we open, my cook informs me that one of the gas lines had a crack and was leaking. I called David and he was here in under a half hour. He got the job done quickly and cleanly. I could not have asked for more. read more

My kudos to Mulhearn Plumbing. When my washing machine valves started to leak, I called Mulhearn Plumbing and they returned my call within 10 minutes. They were in Long Beach at the time, but said they would come to my house within 40 minutes. They were prompt and professional. I truly cannot believe how fortunate I am to have found such an excellent plumber. They know what they are doing, neat and clean and honest. I would recommend them for all your plumbing needs. read more

Great guy, fixed my sink... And had a fair price. Anyone looking for a experienced plumber look nowhere else!

Reliable. Trustworthy. Honest. Knowledgeable. Experienced. Professional. Do you need anything else when looking for a plumber!? Dave has done work for my parents over the years and when I bought a condo, he was the first person I called for assistance in some plumbing issues. More recently though, when I could hear running water, but no water in sight, I called him right away! Within a couple hours he was at the condo and able to diagnose what/where the issue was. In addition to the large issue at hand, there were a few other issues he noticed that needed to be addressed. Some work was done immediately and he came back the following business day, first thing in the morning to finish the work. Highly recommend Mulhearn Plumbing. Thank you, Dave!!! read more
