He was incredibly knowledgeable, Friendly and timely! He wasn't able to fix my issue, but he recommended someone else who could. Super helpful and genuinely cares! read more

We recently contacted Sergio to replace our washer wall box valves (they were old / leaking) and the whole process was extremely easy. He was immediately responsive providing a reasonable quote and could come do the work as soon as we wanted. His communication was great, he answered all our questions, arrived on time, completed the work fast, cleaned up after himself and he was polite and friendly as well. We will be contacting Sergio for any future plumbing needs and would highly recommend. Thanks Sergio! read more

Sergio was great! He is very professional and knew exactly what our issue was with just a glance. He's extremely knowledgeable and honest with his recommendations and work. Extra brownie points for showing up taking all necessary precautions. Not only did he wear a mask and keep his distance but he put booties over his shoes before entering our home. That was very appreciated seeing as we have a newborn, you can never be too careful in these unknown times. I highly recommend him and his team. read more

I am pretty handy but there are lots of things I don't know (transmissions, calculus, Finish, the list goes on) including plumbing. I need an honest advisor in those situations, someone who will help me and not take advantage of my obvious ignorance. Sergio is that guy. He is knowledgeable, honest, reliable, helpful, kind, and just a cool guy. He showed up on short notice, told me what I could do on my own (and told me how) and was very reasonable for the things I couldn't do myself. I'm happy to have found him. He will be "my guy" from now on. I would keep him for myself if I could, but I like you, so I'm going to share. If you need any kind of plumbing related work, give him a call. See Mom, I am sharing. read more

I have no reason to believe he does not do good work. I have every reason to believe he engages in a ridiculous level of price gouging. My sick elderly father was getting out of the hospital and his water heater was not working. Sergio came by and babbled some horseshit about how he didn't know what the problem was and he COULD order $700 or $800 worth of parts but it still might not work and then you can't return the parts. He suggested to just replace the 40 gallon water heater. I don't live in the same city as my father and had, coincidentally, just gotten out of the hospital with 6 broken bones from an accident. Sergio said it would cost $2400 to replace. Because my father (and his roommate who was home) didn't have a working water heater i agreed to this charge. I asked for an itemized receipt to see how much these different parts cost but he vehemently refuses to give an itemized receipt and he also says (i have direct quotes from him via text) that he does not charge an hourly rate either- he charges by the job. In other words- he tries to assess how desperate people are to get their plumbing fixed then slides an insane price right out of his ass. I asked a contractor friend who works on multimillion dollar houses in LA how much it should cost and he said about a grand. I asked a plumber here in LA that i know how much and he said max 1400 and that 2400 was INSANE. Because my father is sick and was just getting out of the hospital and does not have much money i asked if he would take 700 for labor (it took him 45 minutes according to my father's roommate). 700 for the 45 min is still INSANE. Do YOU make that much money?? He refused to take it and said he would go to my father's house and take back the water heater (his purgative). So i had to pay the whole amount which, admittedly, i did agree to. That's ONE THOUSAND SEVEN HUNDRED DOLLARS for 45 minutes work. If you think that's even remotely reasonably i suggest you hire Sergio to do your work. I'm sure he'll do a good job. read more

Kitchen sink was clogged and in need of a plumber quick. My local Ace referred Sergio's Plumbing. I could not be more happy with the service provided and prices are very fair for the work they do. The technician showed up on time, was very professional, explaining too me what was being done and why. It ended up being a monster clog but he got the work done and all is working great!!! So glad too have found Sergio's. read more

Highly recommended! Sergio responded quickly to my urgent situation involving a leaking gas valve, and fixed the problem in a timely and professional manner. The price he quoted was reasonable, and was exactly what was charged after the service was completed. I will definitely entrust Sergio with any future plumbing needs, and feel confident recommending his services to others. read more

Our toilet went out last night and I called Sergio this morning and he was able to provide a quick quote over the phone and came out to fix the toilet this afternoon. I really appreciated his lightning fast service and was so easy to work with! read more

Amazing service! Sergio came to my rescue. I was puzzled why my water bill doubled in one month. I suspected a leak and I inquired if he can look into this matter. He offered a free inspection to find the cause of my leak. Voilá! Within minutes of inspecting my home inside and out, he found the culprit pipe. He made sure and re-read the water meter and suggested to me what should be done to fix the matter. He gave me an estimate cost prior to repair and he immediately fixed the situation along with his employee. I'm super pleased with the service. He came the same day because I was worried to waste anymore water. Sergio was super professional. I highly recommend his servie. I also love to support the local business in the area. He was in fact recommended by another competitor since they couldn't provide service the same day. I lucked out. Sergio came to my rescue. I would absolutely hire him for future plumbing projects. PS. He also has affordable rates! THANK YOU again Sergio! read more

This is my go-to plumbing service. Whenever I have an issue, they respond quickly and give fast, clear and fair quotes. I have recommended to family and I just keep them in my contact list just in case. Great service...incredibly professional and responsive. What else could you ask for? read more

Fast response, very professional, affordable pricing! Thank you so much for your services! Support local businesses!

I highly recommend Sergio's Plumbing. They have been to my house on many occasions. Their very polite, Always on time, Very skilled and trustworthy. I wouldn't call anyone but them to get the job done . read more

My shower was shooting out water from behind the handle. It was not something I could have fixed myself. I called Sergio's Plumbing. He came to my house the same day and at the time he said he would arrive. He was masked up and placed shoe covers on. He is the most professional, competent, and friendly plumber I have met in Vallejo for the 50 years I have been living here. My shower is working perfect. His price is very good and warranty for his work is exceptional. I highly recommend Sergio's Plumbing. I will never use another plumbing service. I have his number locked in my phone. read more

Very late post however better late than never. Last November 2020, we had a leaking kitchen faucet. Water immediately went into the faucet enclosure below the sink. I was very fortunate to speak with the owner Sergio. He asked me a few questions then immediately recognized what the problem was. The metal lock on the pull out was loose. He taught me a quick fix which saved me $100+. Also kept us all safe from virus exposure. Mr. Sergio has earned our business. He is experienced, honest, trustworthy, caring and has integrity to do the right thing. We wish him and his staff the best and that his business excel tremendously! Thank you Mr. Sergio! read more

Because of the great yelp reviews, I gave Sergio a call when I found both my bathroom toilets backed up. The call went to voicemail so I left a message but kept making calls since this was quickly becoming an emergency situation. After I'd made other arrangements, Sergio returned my call. I appreciated his professionalism and the fact he got back to me as quickly as he could. While I didn't use his services this time, I would definitely consider calling him in the future. read more

My kitchen sink and laundry drain system was clogged up, called this person and don't even a call back or text... his voicemail says that he'll call back as soon as possible, but I guess he still busy after 3 weeks.... Ended up going to home depot, buy tools and do it myself... read more

I have never had to call a plumber but, was nervous from hearing horror stories from friends with either the experience or the cost. Sergio had excellent customer service and was extremely affordable. He made my first plumber experience hassle free. Our toilet would not flush and after a few questions on the phone regarding the problem, Sergio says he will be at our house in 15 minutes! I was shocked at how soon he was able to come! He arrived as promised 15 minutes later, determined what was wrong, and had it fixed all within about 15 minutes! I highly recommend them! read more

I have been a customer of Serio's Plumbing for several years. He is always knowledgeable and gets to me on time. I am happy with the work he has done for me in two different properties. Also appreciated is that he explains clearly what the problem is and how it needs to be fixed. I highly recommend Sergio. read more

I would highly recommend Sergio's Plumbing. I was in a bind and they were able to give me a quote and make an appointment within minutes. They showed up on time and were able to replace the kitchen faucet within the hour. They even took the time to fix a water flow problem that I was unaware of. I was impressed with how friendly and professional they were. They answered my questions and concerns. I would definitely use their services again. read more

Quick to respond on a busy day, helpful and a true expert in his field. We've become regular customers because we are incredibly pleased with the work and prices. read more

Wonderful service! Sergio came on time, was friendly, finished his job quickly and efficiently, and his cost is reasonable. Would totally call him again for any future plumbing issues. Highly recommend. read more

I'm done. I've waited for over a month for some progress on a small bathroom fix. -- no response - no follow up...left in limbo - I'm done.

Sergio did a great job with our kitchen sink. He keeps it real and honest, which is a plus! We will definitely use his services in the future. read more

I used to use ABC Drain, but they were sold and the new owners I found to be not all that professional. So, I called Sergio last night because the main sewer line from our house was clogged and the downstairs toilet was backing up. I also called 2 other companies. I never heard from the other two, but Sergio called me back right away (around 7:30 pm) and said he could come out the next AM, and provided me with a verbal estimate. This AM, he showed up on time, and was really friendly, professional, and super efficient. He cleared our drain for less than the quoted price, and did it quickly. Yay! I will be calling Sergio in the future for all our plumbing needs, not just a clogged drain. He made a really good impression and I highly recommend him for a great local plumber. read more

Very prompt responses and correspondences via Yelp. Availability and timing on such short notice was awesome and very appreciated. Price is reasonable and the plumber was FAST but thorough. Credit cards accepted is a bonus. Very happy customer here. read more

Just a leaking bathtub faucet, so I yelped 4 plumbers on a Saturday morning. 3 of them said they could come Monday or Tuesday, which was what I asked for, but Sergio asked me to send pictures so he would have the right parts when he came. This impressed me, so I hired him. It was secondary that he quoted $190, when the only other one with numbers said between $200 and $300. Sergio came as scheduled with the part. He said up front that if I paid with cash, he would knock it down to $170. Then the job went easier than expected, and he made it $160. He was in and out in 20 minutes, and as friendly as you could be. What more could you ask for? read more

Sergio came over about 20-30 minutes after I called. It turned out to be a broken sewer pipe. He was so hard-working and diligent. The clog was further out than his snake could reach, so he recommended a larger company. He barely billed for his time and effort, and he was extremely professional. Well, the next day they eventually found the clog 150 ft out, which was park property. Mind you, this is an incredible distance away from my property, so this situation is rare. Due to an initial misdiagnosis by the mobile home maintenance staff, I was reimbursed for both plumbing services. It was a tricky issue, but we will call Sergio first for home plumbing repair. read more

fast easy quality work. on time. reasonable price. fixed my bathtub faucet. friendly guy too. recommendex

I was informed my city water department that I was using 700 gallons of water every three days. Of course they didn't make a recommendation on a plumber, so I jumped on Yelp and called Sergio's Plumbing. They were fast and efficient. They came and gave me a no charge estimate and informed me exactly what needed to be done. They even encouraged me to contact other plumbers to get estimates. After inquiring with other plumbers, I came right back to Sergio's. Their customer service was impeccable, and the staff informed all along the way of what they were doing. I'm throughly satisfied with the quality of work and will definitely use them again if I have too!! read more

Very professional and best prices in Vallejo! There is a reason he is booked so far out if he's unavailable right away and that's because he's the best in town! I'm sure you remember John and Jude from ABC, when ABC was good. Well John and Jude retired and they wanted Sergio to take over for them, and rightfully so. Sergio can be trusted. He's fair and honest. You can really trust him. He will quote you a fair price and will bring good men over to you home to get the job done as quickly as possible. So please give Sergio's Plumbing a call first when you need a plumbing job done. You won't be sorry. He's a good guy. read more

In 2018 we had a new Whirlpool water heater installed. Oct of 2020 the burner went out and we called Sergio's Plumbing and they instructed us to contact Whirlpool to request a new burner and call them back as soon as we receive it. The part came in and we called them back. We have been dealing with plumbers for decades now and decided to walk our dogs while we wait. Our walks are about 20 minutes and we have never had an experience with a plumber that comes out in less than an hour. In the short time we were gone they had come out to the house. WOW. Talk about speedy service. We called and apologized and they were very understanding. They returned within minutes. Not only did they provide fast service, they were also very informative on how we should handle Whirlpool and were professional and extremely affordable. I wish I had submitted a review at that time. It's Oct 2021 and once again the burner has gone out. Without hesitation we once again called Sergio's Plumbing and received the same outstanding service. It is our greatest hope that they are able to stay in business for many many years to come. We will never purchase a Whirlpool product ever again. read more

Sergio responded quickly to my need for a new refrigerator water line, as we had been living without a fridge for several days, and needed the new one installed asap. I contacted him in the evening, and he communicated with me promptly by text and cell phone photos during the evening, to confirm the precise problem, so he could be sure he had the right part when he came out this morning. He arrived promptly at the time that he'd promised, with everything he needed, and fixed the problem without incident. I will definitely call Sergio next time I have a plumbing issue! read more

The hot water line into my washing machine was broken and we need to replace our faucet in the laundry room. My aunt gave me Sergio's number and I called him and inquired about his service. He came the next day and inspected the problem. Gave us an estimate and scheduled service as requested. Service was fast and professional. Everything the he said that had caused the problem were correct. Very knowledgeable. Charges were very reasonable. I highly recommend them for your plumbing needs. He is a local Gem. read more

I called Sergio and he answered the phone! I needed a shut-off valve on the gas line to my kitchen stove. He came the following day to look things over and gave me pricing for a few options that might be necessary. The existing piping was crowded with a head-scratching unorthodox layout. The next day he came well-organized and got started. The work was completed within an hour (including clean-up) and the cost was in his lowest estimated range because everything executed simply and easily. He is knowledgeable and experienced and explained things as he went along. I will use him again. read more

I recently used Sergio for a project at my Mom's house. He was prompt and very accommodating! We needed some fixtures replaced that were too heavy for us to bring in and he went out of his way to pick them up for us even though there was a mixup that meant a one week delay. So impressed, I would highly recommend him for any plumbing job. read more

I had a great experience with Sergio and his business. I called in the morning and he agreed to come that day. He even cut his lunch short so he could fit the call in after a previous appointment went longer than expected. Him and Danny were nice and extremely knowledgeable. They fixed all my plumbing issues promptly. They were just all around good people and I would definitely recommend his business to family, friends, and those in our community. read more

Sergio's plumbing did a great job replacing my water heater. Their price was very fair, and Sergio was extremely profesional, polite and knowledgeable. I will definitely give them a call if I ever need any plumbing done in the future! read more

Sergio saved the day! Our hot water heater gave up the ghost and I didn't know where to turn. Seeing his excellent reviews on yelp I gave Sergio a call. I couldn't be more pleased with his responsiveness, his expertise and his friendliness. Moving forward, Sergio is my plumber! read more

Sergio agreed to remove and install a new toilet. The day he was supposed to do the work, he totally ghosted me. No call, no show. I texted him and he never responded. read more

Sergio came covid-ready with a mask, he was safe, and did an awesome repair.
