Recommended Customer Reviews

Awesome! Quick and very professional!
I had a water heater that died that needed to be replaced. I got a new water heater installed by Thomas Plumbing and he was able to install it perfectly with the existing piping.
I highly recommend them.

I was very impressed with the work done by Dick, the Thomas Plumbing plumber who diagnosed and fixed a water leak problem at my home. Dick showed up just a few hours after we called. He quickly theorized we had a broken drain pipe in the wall behind our sink. He carefully cut into the wall and found that was indeed the case. The broken joint was in a difficult spot, just above the concrete footing of an outer wall of our home. Despite the difficult position of the break and the cramped space under the counter he had to work in, Dick was able to replace the pipe and fittings there and fix the problem in less than two hours from the time he arrived. And he cut into the wall so carefully it was not too difficult for me to replace the sheet rock he had to remove. I really appreciate the good work he did and the pleasant, positive attitude he had the entire time he was here. I highly recommend Dick and Thomas Plumbing.

We usually use another plumbing company in Morgan Hill but they were not doing home service due to Covid, so we had to look for another plumber and decided to try Thomas plumbing -Morgan Hill. First time experience and it was a very poor quality service. Took 2 trips and 4 phone calls for the work to be properly completed.
I purchased a faucet for my parents house, and contacted Thomas plumbing -Morgen Hill, to remove the old one and replace it with the new one. Their technician came in at 1:31 pm, installed the new faucet , texted me at 2:46pm that he was done. And we were sent a bill for $296.
I went over my parents and saw the faucet was loosely installed , water leaking down into the vanity drawers and under the sink. I called Thomas plumbing to report the leak issue and requested fix. I was put through Dave, who appeared to be the owner . he denied any workmanship issue then accused me of trying not to pay. I send him video and pictures, of the loose faucet handles and water under sink. Then called Dave back on to follow up, he agreed to sent the technician back to fix it. This was while no apologies made or empathy for the inconvenience. After they corrected the faucet and when I went there to pay, I asked for a breakdown of charges . They stated $296 was for 2 hours of labor. I informed them that their technician was there for a total 1&1/2 hr . They referred me to Dave. So I Called Dave the next day, I told him that my parents are elderly and on fixed income so I want to make sure they pay a fair charge. Dave insisted that we must pay for 2 hours despite proof i had via Ring camera and technician time of text. Dave said that tech spent 2 hours and part of it was the paperwork he was doing while in his truck.
I agreed to pay the due bill but I won't do business with them again. Thomas plumbing Morgan Hill is poor workmanship Quality, poor customer service, and were dishonest about the charges.

I cannot say enough about the service that I received from Thomas Plumbing! After my last plumber flaked out on me for a larger job, I called Thomas Plumbing and I had a technician knock on my door an hour later. I had a water main leak which we thought was in one spot, but he pinpointed the actual source. He didn't have the part that he needed and he couldn't get it at Home Depot so he returned the next day as promised and stayed until it was done. He returned the next day (again at the promised time) to turn on the water and ensure that the leak was corrected. I'm so happy at the excellent service that I received that I can say Thomas Plumbing is now my go-to company for all of my needs!

My water heater leaked all over the garage and under my house, eeek! Called Thomas Plumbing and they sent someone out right away, found the problem and recommended that I get a new water heater. They did the fix that afternoon. They were very pleasant to work with and I would recommend calling them for plumbing issues. I will be calling them again! Thanks!

My new favorite plumber in Morgan Hill is Thomas Plumbing! We had two back-to-back issues, a leak in a kitchen pull-out faucet hose and then a bad air gap and clogged pipe in the dishwasher which came to a head the very next day. Between Ricardo and Dean who each responded to the various issues, each was handled very professionally and competently. And because the two issues occurred so close together, Dave helped out by discounting the labor charges. Thanks to all of you!

Thank you for sending Cody to repair my kitchen (under sink) plumbing leak. He did a great job. He located, repaired the leak and additionally replaced several deteriorated plumbing connections plus a garbage disposal unit - all on their way to cause problems.
I felt he did a great job - kept me informed as to the repair progress and when finished - left a cleared work area. For any future plumbing needs -I would certainly contact Thomas Plumbing.

Once again Thomas Plumbing came through quickly and very efficiently! Plus, Patrick was a joy to have fixing my toilet, very personable and even gave me a senior discount! I'm a fan for
Another visit for a different situation and another stellar outcome and service, this time by Cody!!! Amazing result and another very personable technician! They are two of the best. So nice to have a great experience with a plumber!!

On Valentine's Day I discovered a big leak under my kitchen sink. With company coming the next day I knew I needed to get it repaired today! After calling 2 other plumbers unsuccessfully, Thomas came to my rescue that afternoon. Patrick quickly ascertained that I needed a new faucet. While I went to Home Depot to buy one he removed the leaking faucet and was ready to quickly install the new one. In spite of having to go to the store, the job only took one hour! Patrick was efficient, clean and confident, and he gave us the senior discount. I was both relieved and very pleased.

Awesome service! They were able to come out the next day. They gave us a time frame and called 30 minutes before their estimated arrival. Patrick arrived and had shoe protectors on ready to get the job done. We had a small leak on our master bathroom toilet. With the holidays, we just shut it off and then it sat for two months. So of course, our issue did not appear to be an issue when help finally arrived as the leaking could not be seen. Patrick went ahead and took everything apart to check and make sure there was no water damage underneath. He replaced the seal and put everything back together in a timely fashion. Highly recommend this company and love the fact we can support local businesses!
