Recommended Customer Reviews

Tim is a reliable, responsible and knowledgeable person. He helped me to install a tankless Waterheater a few days ago. He provided me with multiple solutions, and I made my choice after his first on site visit.
He came in on time and also kept my place clean.
He would make sure everything was good before he left my house.
I highly recommend Tim.

They gave me a quick, fair quote, didn't charge me extra for connection to the underside of the sink, and did the job in a fair and expert manner connecting my sink handles and pipes, and very nice manner as well. Good plumber!

OMG - can't tell you how relieved i felt when Hector from MTZ Plumbing showed up - I had a 3 day under the kitchen sink leak.
Hector - one of the co-owners - not just fixed the leak but explained how it happened and fixed it in a way that there is a shut-off valve now to my water filtration system. Super professional - customer service is as good as it gets - there is a reason this company is all 5 stars! They are also 24 hour service - the other companies recommended by the Home Warranty company say they will get back the next day - not good when you have an active leak!
12/1/21 UPDATE
Alex from MTZ Plumbing came out to connect my water filter and found and fixed a leak. Apparently that leak was probably there for awhile but only showed up after the replacement water filter was installed.
This company is first rate by far - super trustworthy

We needed a reliable plumber to assist in coordinating a meeting with our City inspector to final our permit for renovations. We were extremely stressed out, needed someone last minute and someone who would be able to work within the same time window as our inspector. Hector, from MTZ plumbing, made it happen. Not only was he friendly and professional, he was able to accommodate the schedule we needed and gave us the best price. Thank you so much for making such a stressful day go so smoothly. Highly recommend.

I have a tankless water heater that needed servicing. I contacted the Rinnai, the manufacturer, and they gave me a list of plumbers in my area that are certified to work on tankless water heaters. I called two of them but only spoke to one. The plumber that I spoke to told me that they would call me back to schedule a time for them to come out. They never called me back. The other plumber did not call me back after I left two voice mails.
I called MTZ Plumbing and I was immediately connected with a live person. We scheduled an appointment for the following day. Hector was extremely helpful and walked me through everything he did. He also looked through the manual to make sure everything was covered. We thought that we had to order a part so Hector told me he would call me later in the week to schedule time.
Hector called me a few days later and told me that the manufacturer suggested a few more steps to fix the issue. he came by shortly thereafter and fix the issue.
I highly recommend working with MTZ Plumbing. They are smart, helpful, honest and they follow up with customers. I will be using them moving forward for any and all plumbing challenges I have in the future.

I asked for an in person quote for: 1) the plumbing in my master bath moved over by one foot for each of my two sinks, 2) for new plumbing to be added in my garage for a utility sink, 3) the valve on one toilet replaced and 4) a drip in the shower repaired. I was quoted $7000!! My regular licensed plumber, which I have worked with for ten years, was out of town for a month and I didn't want to wait: he had quoted me $1200 for the same job. I've decided to wait. Make sure you get multiple bids before going with this company

Can't say enough thanks to Hector and his work clearing out our sewer drain. We called multiple plumbing companies and was being quoted to rip out drains and replace. Hector was the first person to actually listen to what was going on, make an assessment and give me different options. What he did was exactly what we needed and from now on, I'm calling him for all of my plumbing needs and recommending him to our family owned retail property management business.
Can't recommend these guys enough.

MTZ Plumbing was very helpful and professional with helping me find the cause of a water leak in my garage. In the end it was a faulty refrigerator and so I had to cancel my appointment, but I can tell with my interactions with them that they are an honest company. I will not hesitate to call them for future plumbing needs.

We saw some water on our kitchen counter dripping through the cabinets. Suspected it was a leak from the bathroom above. MTZ Plumbing responded immediately to our ask for a quote and sent out a technician for free! The technician said they could not service the request since we had cabinets and there is no access to the pipes. He was kind enough to recommend someone else who could help us and also checked our neighbors home to make sure there aren't any leaks there. I really appreciate their promptness and honestly.

Hector is the best. I've had him out twice now for two separate issues. He is friendly, responsive, timely, professional, and wears slips so as to not track in any dirt. He will explain what the problem is, what caused it, what can be done, and what the cost (and sometimes risk!) of certain actions and repairs might be before he puts the work in.
First time out, he replaced the shutoff valves for my kitchen sink when I had replaced the faucet, but found I couldn't hook it up because the old shutoff values had old weird soldered copper pipes rather than a threaded hookup. He took the time to explain where the water main shutoff was to the house, how to fix the problem, and also answered all my questions about also adding in a reverse-osmosis water filtration system while he was replacing the shutoffs. The sink works like a dream now and the water filtration system has been a game-changer, especially during quarantine where most of what we are drinking comes from the tap rather than out at work/restaurants.
The second time he came out, he fixed an issue I had with my shower leaking. He was running a little bit late, but called me multiple hours in advance to let me know so I could rearrange my schedule and he actually showed up at the new time when he said he would (professional!!). He simply tightened up a few things, said there was no underlying problem, and didn't charge me for the ~20 minutes of service (and education on how shower valves work!). Look no further, MTZ are the guys you want
