Recommended Customer Reviews

Had a leak in a new water heater.
My wife saw Tom on another job and asked if he could help.
As soon as he finished his current appointment Tom arrived at our home and after throughly checking the water heater check our water pressure.
Turns out that our problem was caused by a faulty water pressure regulator.
Tom came back a few days later, replaced the regulator and solved our problems.
I would highly recommend Tom!
Very professional, efficient and all around nice person.

We needed service for lowered water pressure, Tom was sent out, immediately diagnosed a bad regulator, I requested if work could be done same day, they graciously obliged. Tom was professional knowledgeable and courteous. The amazingly quick response to our call and service thereafter was top notch, thank you guys!

We think these guys are tops! We had a plumbing blowout when a hose bib got jarred outside the wall and created a leak inside the wall. After determining the repair to be well beyond what we could tackle ourselves, we contacted them with our details and were relieved to hear a duo would be finishing up with their project and available to stop by afterwards. A few hours later they arrived, listened to our story l, then made their own assessment. Being trained professionals, they saved the day very efficiently. (Our foolish plans contained tools that cost more than the repair, honestly.) The office staff I spoke with was friendly, understanding, and very helpful throughout. Our hot water heater is needing attention, we believe, I'm absolutely going with this company.

Tom with John Mahany Plumbing arrived right on time. California state law requires service contractors to give a 4 hour time frame for service calls, JM Plumbing gave a 1 hour time frame and arrived as committed. Tom was courteous, efficient and handled my issue in no time. I recommend JM Plumbing for the reasons I stated as well as their excellent standing with the State Licensing Board, Better Business Bureau A+ rating and accreditation, and great Yelp reviews. I now have a reliable plumber to add to my list of home repair and maintenance contractors.

Had a leak and the main shut off to the house was also broken so I could not shut off the water. They came out within 1.5 hours (despite it being late in the day and close to closing time), temporarily fixed the leak, and then came back just a few days later to replace the broken valve. The Technician (Tom) was kind, professional, informative, and efficient. The folks in the office were responsive, friendly and helpful. Price was very reasonable. Can't recommend them enough!

Awesome experience with John Mahany Plumbing! They were affordable, responsive, and flexible with our job. They came out and gave us a quote, and once we accepted and paid our deposit, got us on the calendar much sooner than I expected. Cecilia from the front office was super helpful and communicative making sure we knew the status of the project. The level of service for our smallish/one day project was beyond what I would expect in the middle of a huge construction boom in the desert. All the construction related companies are getting inundated with requests for quotes and jobs, and yet, we felt like a priority. I will most definitely use them for future plumbing needs.

These guys were the first ones to answer their phones and called us back. They came to our house the same day to look at the problem and fixed it the next day. They were both very professional, knowledgeable, punctual, and friendly.
We had another leak the following week and they were able to get it fixed the same day as well.
It's hard to find reliable professionals in this desert and we can't recommend John Mahany Plumbing enough.

They installed my gas lines from the propane tank to the house and then to the stove. They showed up on time, did an excellent job, they were quick, courteous and professional. I will be hiring them again for sure! I highly recommend them.

Not thrilled with Morris . No customer servi e just think.a rude individual and a disappointment as a plumber. Go else where and let someone do the job right.

Morris came to the house a few months prior to do an estimate about changing 3 toilets, multiple faucets, shower heads...He went back to his office and sent us a lists of choices with prices. Because of COVID, month long holiday trip...we were not able to schedule an appointment until now. Yesterday, Tom and Luis came to the house to start the job and finished everything by noon today. They worked on every fixtures in every rooms of the house in addition to replacing the exterior fixtures. They were fast, thorough, and extremely clean. We were really pleased with their work and even more pleased with the price. We will definitely use them again!
