I couldn't be happier with the service I received! From start to finish, the entire experience was smooth, professional, and stress-free. Alex arrived right on time, quickly diagnosed the issue, and explained everything clearly before getting to work. The repair itself was done efficiently and with great attention to detail, and it's obvious they take pride in doing the job right the first time. They also made sure everything was clean and tidy before leaving, which I really appreciated. What really stood out was the honesty and transparency--no surprise charges, just fair pricing for high-quality work. It's not always easy to find reliable service like this, but they definitely exceeded my expectations. I highly recommend them to anyone in need of plumbing services and will absolutely call them again in the future! read more

I had an excellent experience with MTZ Plumbing. I reached Hector by phone (no wait), and scheduled the appointment. We actually had 5 jobs in the course of a week (May 26th - June 4th 2026): 1) Removed badly corroded faucet and replaced it. Work was great, and it has been functioning perfectly. 2 and 3) Replaced p-trap on sink, and replaced the two shutoff valves on the same sink. Again - flawless work. 4) Installed a 3 filter water filter (a Kind Water filter system) for the house (at the water input in the garage). Excellent planning, design, layout, and execution of the assembly. The finished work looks excellent, and the filter is functioning well. 5) Debugged, and fixed, a weak water input to our refrigerator's water and ice maker system. The water flow is much better now. Hector's work was not only excellent, he kept us posted on the schedule and arrival times. Also very meticulous cleanup after the work - i.e., very respectful of the property. Honest, polite, hard working, and skilled at his craft. Thanks! read more

Excellent service. Identified leaks in hidden valves. Very reliable. Also took care of dishwasher and faucets. .

Alex and Anthony were awesome! My usual plumber was busy so he referred me to MTZ Plumbing. I called and Alex answered right away. I had a water main leak and clogged kitchen sink drain. Alex scheduled me for the next morning. Alex arrived promptly the next morning and talked through options for repairs, and answered all my questions. He gave me pricing up-front and was open and transparent. He was very patient and easy to talk to. Once we agreed on what to do, Alex and Anthony got to work and finished everything the same day with minimal interruption to the household. They did a great job. The gave me all new plumbing for the water main assembly, including a Moen Flo meter. It looks much better than the old stuff, and everything is working great now. I will definitely call them again in the future. read more

MTZ is a great plumbing service!!!! They fit me into their schedule on short notice and did a fantastic job. Alex was professional and resolved my plumbing issues quickly and effectively. Their prices are very reasonable. I've used 3 different plumbers over the past several years but for my future needs MTZ will definitely be my choice. You can't go wrong with this company. read more

MTZ Plumbing was bar none the best plumber I've had the pleasure to work with. Hector came out to install our Pentair Water Softener and programmed it. He completed the job in record time! He wanted to ensure that the water was soft enough for us so he came back out the following week to check and did not even charge us for the extra visit. MTZ gave us exceptional service and had very reasonable pricing. I will definitely use them again! read more

The guys are on time, have a great work ethic, and are very tidy and respectful of property. Will hire them again for sure.

My grandma (who is 93 and lives solo) needed a drain pipe replaced. From the initial call to the service, 5 stars all the way. My grandma was very happy with every aspect of the service and felt like they were honest. They showed her the before and after photos. She is very pleased. Thank you MTZ for being so good to my grandma. read more

This is about my plumbing issue, all my drains were backing up at that time. It was around 7pm and wanted to fix it ASAP and picked MTZ through Google search. MTZ side came earlier than expected and job was done quick. Here are some information for other customers though. I had to hear too much warning "you still have to pay even if it is not successful" and made me decide to go or stop, payment for visiting is still pending. I asked him to snake the pipe and resolved right away. He named the price and I paid the same price of my TV, maybe it is regular for night time. Can't complain as I agree that "the real price will be decided on site depending on situation". He also kept recommending that digging the ground will be the best option for any of coming issue but w/ price of 10x I've just paid. Well again, he maybe right I maybe wrong, just sharing my experience. read more

We were attempting to replace an old shower faucet cartridge so we can easily turn on and turn off the water. It took too much time and strength to push and pull that lever, especially for kids and the elderly. We were able to pull the core out, but the rest of the cartridge was still stuck in the valve. With our small puller, extracting the whole cartridge was not an easy job. The 45-year old original Moen cartridge in this faucet was literally part of the valve, stuck on so tight. With the core out and the valve exposed, we couldn't turn back on the main water line until we could 1) somehow replace the cartridge or 2) replace the entire valve. Doh! On a Sunday too! In comes MTZ to the rescue. In the San Jose area, there were only a handful of 24/7 plumbers available on a Sunday. The only quick answer I got was from MTZ. Before agreeing to their service on the phone, they went over their pricing and the additional Sunday service fee. Of course I agreed because we needed to turn on the main water line that night. The MTZ van arrived 25 minutes after the initial phone call. Hector was very professional, with shoe covers and mask. He knew exactly what the problem was and explained what the options are IF he couldn't extract the cartridge. Using his industrial-strength cartridge puller with a lot of elbow grease and time, Hector was able to pull out the old stubborn cartridge without ruining the valve. He made the impossible possible, and solved our problem. Before Hector left, we replaced the cartridge with a new one, turned on the main water line into the house, and made sure our shower faucet worked properly with no leaks. Now the water is easy to turn on and off. Like new! read more

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 read more

A pressure assist vessel required replacement. Although I'd received the parts from the manufacturer I was not able to instill it do to an injury. Hector gave me a good price and estimated it would take about an hour. Almost one hour to the minute, now the toilet flushes perfectly without leaking water. Excellent job. I would definately recommend MTZ Plumbing. read more

Finding a good plumber based solely on Yelp ratings is extraordinarily difficult. They all have very high average ratings, though many are unreliable and incompetent. Several 5 star companies I contacted arrived many hours later than the agreed-upon time, and sometimes not at all. Other services show up punctually and are even friendly, but don't know how to do the simplest job, or do it poorly. MTZ Plumbing and its owner Hector are a very welcome exception in both regards. To begin with, they're highly professional. They have been doing plumbing work at my house for two years, and they always come exactly within the 2-hour interval we agreed to, with text reminders and phone calls if they are closer to the end of the window. Hector is also a highly skilled, knowledgeable plumber. For instance, he successfully installed Hansgrohe faucets with replacement cartridges and handles when other plumbers claimed that they couldn't do so, and more parts were necessary. Lastly, he is fair and reasonable with his pricing, as well as any further issues that crop up with larger jobs. Again, all Yelp plumbing companies have high average ratings, but MTZ Plumbing is the best I've come across in the Bay Area. read more

I would give MTZ Plumbing 6 stars if I could. They live up fully to their ratings. I found them online and what a find. They were responsive, knowledgeable, and incredibly thorough and honest. It is wonderful when you find someone like Hector and MTZ with the utmost integrity. He is fantastic and went above and beyond to get to the root cause of our hot water issue, and dealt with the parts mfr to get us a free replacement. It is comforting to know we have someone so reliable and reasonable we can call for any future plumbing needs. read more

These guys are great, and I especially want to thank Alex! They replaced our water heater this past month and they were professionals, timely, and communicative. They came out to evaluate our current system and pulled a quote together for us. They explained why they made the recommendations they did. The installation was smooth. We found a few more issues that they came back to fix. Alex even helped my husband look for our dog who went missing in the afternoon. The dog was found in the garage anyway, these guys are my new go-to plumbers. Thank you for everything! Amazing work. read more

We had a clog that another plumber couldn't fix and Hector from MTZ was recommended by another plumber who couldn't come. Hector was able fix the clog, and was thorough in checking for other issues, he provided great recommendations so that we can avoid issues like this in the future. The first plumber failed to solve the issue after 2 hours because they didn't have the proper tools or expertise. MTZ Plumbing fixed the issue right away, he had the right tools and he had great communication skills. read more

Our water heater was leaking and it was a weekend! We were afraid to leave it until the following weekday and when we called MTZ a plumbing specialist was at our house within a couple of hours. Tim was polite, professional and friendly. The old water heater was removed and a new one installed in record time. Thank you MTZ and Tim in particular! read more

I only have good things to say about MTZ Plumbing, they're true professional. Hector provided us with a detailed estimate, which had a reasonable cost, compared to other quotes we got. Alex and Anthony, who did the actual work were great: they were knowledgeable, friendly and polite, they communicated their time of arrival in advance, their estimated time of completion for the job turned out to be exact, they explained the repair process and documented the repair with pictures. 5 stars without hesitation! read more

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. read more

Hector is great. My kitchen sink was clogged. I scheduled appointment with MTZ Plumbing at the midnight and I received response at 5am on last Sunday. And Hector gave me available time between10am-12am, which I accpeted. He showed up on time, started work quickly. The problem was not as simple as I expected. It was not the p-trap but somewhere deep in the pipe collapsed (under the concrete slab). Hector tried small snake and bigger snake, and later used a sewer camera to show me the problem. In the whole process, Hector is professional, polite and super helpful! I would highly recommend Hector and MTZ Plumbing. read more

Hector was great!! Our home's kitchen sink suddenly clogged and we couldn't even do laundry during that time because water would gush out of the sink's drain. I called during late evening and MTZ Plumbing was very responsive to help arrange a time to fix our drain asap the next day. Hector was also on time and very detailed on explaining what service needs to be done in order to fix our problem. The price was reasonable since we needed replacements in the end and everything was fixed and working perfectly in less 2 hours upon his arrival. Highly recommend those in Bay Area to use MTZ Plumbing! read more

I had a sewer backfill with a leaky toilet at 8pm. The bathroom has flooded to the baseboard. Called my home warranty company and multiple other companies and no one could come at this time. I was super relieved to find MTZ Plumbing who was able to sent someone out within the hour. After the call, the communication was superb. I received text message update on when the the contractor will be out, and Hector called me to give a more accurate ETA of 20 minutes. Like many other reviewers, I can't say enough good things about Hector from MTZ. He's super nice and professional. Explained everything he did in a friendly and educational way. He was also very skilled, and resolved all of my issues efficiently; I had a sewer main backup, offset leaky toilet, and stuck kitchen drain. He unblocked the mainline and showed me the root intrusion via camera, and recommended me to call the city. Then he reset the leaking toilet which wasn't installed properly. Lastly, he unblocked the kitchen sink drain and made sure all the pipe is clean, and double checked there's no leakage. Hector even went out of the way to check all three bath room toilets and sinks, and gave recommendations about maintenance and leak prevention. I learned a lot about residential plumbing, city practices, in one night. I'll definitely be using MTZ plumbing again and recommending them to all my friends. read more

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. read more

I have used them many times before and they always have a great attitude and always clean up after themselves great service is hard to find these days. read more

On a Thursday, our showers/sinks only gave us cold water, so we knew it was the water heater since the pilot wasn't igniting. I did research to find a well-rated plumber and found MTZ. Called the number on Friday, spoke to Alex who was super informative and friendly and gave us ideas on what the issue could possibly be. We scheduled an appt for Monday (Alex mentioned weekdays could affect pricing) and within 30 minutes of giving us a call the day of, he showed up without struggle to find our home. He found the issue and unfortunately we had to replace the entire water heater, but Alex made the process super smooth and easy. Him and Hector were there for less than a few hours and holy moly, we were impressed! Alex explained how to maintain the unit to hopefully make it last up to 20 years! He gave us some super useful tips and we're so thankful he helped us save money. I'm so glad we don't have to shower with ice cold/boiled water anymore read more

Hector did a great job unclogging our pipes. He was pleasant & professional. No mess at all. Thanks for the great prompt service! Donna & Jeremy read more

My new favorite, go-to plumber! Hector came out on a Sunday night for an urgent issue and he got us back in business in no time. He answered all my questions, explained everything he wanted to do, and got it fixed quickly. Bonus that he is a friendly, professional, polite dude who really cares about providing great customer service. Highly recommended. read more

MTZ Plumbing just completed a major plumbing job at one of my properties in Sunnyvale. Alex was the plumber in charge of the whole project. He was very professional and kept me inform through out the whole process, It took a long time to finish due to extensive tree root damage and old pipes. The front lawn had to be dug up to perform the repairs. I thought it would need to be replaced. But no when the job was complete, it looked great. If you need any plumbing work, call MTZ Plumbing and ask for Alex. read more

We have been using MTZ plumbing since our recent move. They are top notch professional providers of quality service. Tim replaced our pressure valve assembly and fixed and replaced several of the old faucets and leaky under-the-sink pipes. They guarantee their work. We just installed the water softener system and Tim and his crew did another round of perfect job. Thank you. read more

Excellent work/service! Very detailed and transparent! Thank you for fixing my bathtub!

Helpful! I called MTZ and explained my plumbing issue. Unfortunately for me, they were booked with other service requests for a couple of days. MTZ was kind enough to refer me to another licensed professional to respond that same morning. Therefore, A+ for professionalism. read more

My daughter had a leak from the upstairs condo staining her ceiling. The upstairs tenant's plumber couldn't solve the problem. She called MTZ Plumbing Inc. and Hector arrived. He diagnosed the problem as an incorrectly installed wax seal on the toilet, explained the problem to my daughter, and affected the solution quickly and for a fair charge. She suggested I call MTZ I had what I thought was a mainline clog backing up in the shower. I called MTZ and Angela and gave an estimate over the phone which included a discount for my daughter's referral and a Senior discount pending inspection. Tim arrived, assessed the situation as a shower clog rather than my diagnosis of a mainline clog which plagued my house almost annually. Tim's solution was to run a cable machine down the shower drain and if that didn't unclog the shower, he would use a larger rooter down the mainline at no additional charge to guarantee a functional shower. Tim was right in his diagnosis and mainline cleaning was not needed. To add frosting to the cake, the bill was $25 less than expected! For comparison, the "Big Box" Rooter service offered free estimates. When the BB technician arrived, he warned me that their new rates were the highest, with a starting point of $500 plus. Forget it! MTZ completed the job for less than 1/2 "BB" starting point. MTZ you are my plumber of choice now: knowledgeable plumbers, clean work, good equipment, fair price, and a break for Senior citizens - way to go MTZ! read more

I requested for a quote and Hector responded immediately, he came out the same day to see the leak. Hector was polite, responsive. However, the quote I received was 5 times more expensive than any other 4 quotes I received. I just cannot recommend this plumber no matter how competent. Please do your work, check around, get a few quotes to compare before you jump in to make a decision. read more

I decided to play a little "Yelp Roulette", and submitted a request for plumbing services to contact me. The idea being that the first one to contact me wins. Hector at MTZ contacted me right away, and told me someone could be there later in the morning. Tim shows up in a mask, and put on two footies before entering the house. I explain to him that I have a leaking faucet in one bathroom, and possible a 2nd leak in another bathroom. He goes in to take a look, and 10 minutes later, shows me the problems in the 2 sinks. He tells me he'll be back in a few minutes with a quote. When he comes back, he shows me 4 different quotes of what he can do, ranked from highest priced to lowest. I opt for something in the middle. He goes out to get some parts, and from the time he arrives, until the time he leaves, he has taken only about 2 hours. I asked him about how long he has been working at MTZ, and he told me that the company is brand new, opening up at the beginning of the year. That explains the low count of reviews, but the 5-star rating (as of today) is true. The professionalism and service was awesome! Highly recommend! read more

Had a broken hose bib pipe where the solder joint failed inside the wall. Unclear what caused the issue. Water was spraying inside the wall and you could see it seeping down the sill plate of the foundation. Of course it was Sunday. Why do all pipes decide to break on Sunday. Opened the wall to see the issue and it was clearly more than I could solve. Called Hector who said he could see me between 12:00 and 2:00. Hector was super kind and very fast. I was particularly impressed with how he laid down a tarp before working. Super polite, friendly and kind. Happy with result and glad to have the water back on. read more

72 Degrees Cooper Brothers (another excellent company) recommended MTZ to take a look at a gas pipe problem. Hector picked up the phone right away, was very nice, ask some questions, then sent Tim to my house the same day! Tim came out, remediated the gas pressure problem, looked around, found some other issues, took some pictures, and talked about some things to look out for in the future. Tim will get some quotes for us, and we'll use MTZ when the time comes. I was hesitant to write this review, because it feels like I stumbled on a secret that I want to keep for myself. read more

MTZ did a great job all around on a full sewer re-pipe of our home. We had 65 yr old galvanized / iron sewer lines in our home that were starting to corrode, so we called a few plumbers on yelp to come diagnose the issue. MTZ responded in minutes and Tim came out for a free inspection within a couple days. He spent about a hour inspecting our whole plumbing system (the two other plumbers who provided estimates spent about 10 minutes). After his inspection, he explained everything he found, shared pictures from under the house, provided 3 project proposals at different price points, and explained the benefits of each. It never felt like he was trying to up-sell anything that was unnecessary, but rather providing information and options. Tim was also super responsive after he left, answering all of my many follow-up questions and working with me to finalized the plan. We ended up doing a full sewer-side re-pipe from the drains to the property line. They worked with us to schedule all the work while we were out of town for a week and coordinating everything through final inspection to be completed before we got back. They sent photos from under the house showing all the new connections and lines, and also showing that they completely cleaned up our crawlspace of the junk previous contractors had left behind. There were a couple of very minor issues that needed follow-up when we returned, but Hector came out the next day on a Sunday to fix those last issues. Overall, they did a great job and were extremely professional and responsive. Highly recommend MTZ plumbing and will call them again in the future if needed. read more

Scheduling was easy and I got a next day appointment for a non-urgent issue. The plumber Tim was personable and fixed the problem quickly and cheaply. Thank you! Will call MTZ if I need plumbing work again. read more

The fastest and most courteous plumbers I've ever used! Our water heater leaked and overflowed into our garage yesterday. After calling 3 other plumbers (after 5pm), Angela took our order and was amazingly responsive. Hector came out at 7pm and he's an extremely nice and professional plumber. He was able to immediately diagnose the problem, replace the water heater, and complete the job within 2 hours. We had hot water last night and no more worries about leaks. Thanks Hector and Angela! read more

I had my sink replaced. Hector, one of the owners, was kind, highly respectful and clean in his prep work through the job completion. He stuck with his estimate for the job even though it took him longer to complete than he thought it would. Additionally, he looked at a couple other different plumbing issues to let me know what the problems were and what the solutions would involve. His plumbing knowledge was good and his support phone staff were friendly and competent. I recommend this company. Lori B. read more
