Very impress by how knowledgable and fast the work was completed. Kitchen sink was both clogged and leaking and he fixed it in less than 30 mins. He was also was easy to contact via cellphone and was even early. read more

I recommend Sergio. We called him in the morning and he responded quickly with a return phone call. He was doing an emergency job, so he let us know he would be able to come that afternoon. He called back to let us know when he would arrive as the time got closer, and when he arrived at the appointed time, he got the job done in about an hour. read more

Sergio has helped me with an urgent repair and a large project in the past 2 weeks. He is super responsive and professional. My urgent repair was fixed right away. With 4 plumbers bidding on the large project, Sergio assessed the whole situation very quickly and correctly and came up with a very sensible solution that addressed concerns for all parties. He stands out right away in comparison with all other bids. He and his team worked over the weekend to ensure a smooth move-in of a new family. I'm very pleased with and highly recommend Sergio's work. read more

Sergio was great. Responsive, knowledgeable, and reasonable.

My mom needed some repair work and looked up on Yelp for a great, reliable plumber. Sergio's Plumbing was near the top of the list with great reviews. So I went and gave them a call. They came within the time given and helped clear out the pipes. Will def be calling back for future service and referrals! read more

I would highly recommend Sergio's Plumbing. Sergio immediately responded to my phone call and understood the problems associated with my shower, which he repaired promptly and effectively. He was extremely polite, knowledgeable and efficient. Sergio's Plumbing Company is the best plumbing service I have ever hired. read more

I have been using Sergio Plumbing for years and cannot recommend him enough. He is prompt, courteous, efficient and extremely professional. This guy knows his stuff and has fixed a wide variety of issues at our home as well as rental property. He is a real gem and Vallejo is lucky to his services available. read more

Called Sergio based on the great reviews, as I have a lot of faith in yelp! based on a previous posting where there was a miscommunication with a customer about reaching him and an appointment being made I asked if he could give me a quote to replace two toilets and give me an appointment time. He gave me a quote (a good one!) and told me to go buy the toilets, put them on 'will call' and to give him a call back so he could give me an appointment. That was on Friday, a week ago. I did just that, and left a message saying the toilets were bought, and under his name to pick up, and when could he install? no call back that night. Next day I texted, called, then got a text back saying someone walked away with phone and that's why no call back for one more day. I said no problem, when can you come? He texts, busy this morning but "I won't forget about you "... No call back in the afternoon. Another day goes by. So finally, I got somebody else. A week later. Cuz I'm stupid that way, and I like to give people the benefit of the doubt. I'm sure this guy is a good plumber and a nice guy, but, my advice to him is: if you are too busy, communicate with your clients: "I won't be able to do it for a week... or until next Tuesday" would have been ok with me. I can plan around that. but all of this hanging on to your availability...no bueno. My advice to customers is: get an actual appointment, and if you can't get one in a reasonable amount of time, move along. Don't hang on there like me! read more

I needed a shit off valve fixed quickly. He showed up, evaluated the job, got the parts, fixed excellently. Friendly, honest, and efficient. I will most certainly use again. read more

I needed to get a plumber out for a slab leak in my garage. I was recommended Sergio's plumbing by a management company. Sergio is based in Vallejo and came out to my property in Antioch to repair the slab leak. Through out the process he was highly knowledgeable and provided the best fix for my issue. Prior to contacting Sergio I was told America's Plumbing was the best place to call for my circumstance. They came out and gave an estimate of 6-9k. They wanted to reroute the piping in my ass. From the initial appt with this company I felt like the guy was a salesman rather than a plumber. They were rude to my sister over the phone as well. Sergio got all the work done with a MUCH LOWER price. Very pleased with his work and has definitely earned my trust. The quality in his work is amazing. Call Sergio for ANY plumbing need. You wont be disappointed. read more

Fast Response, Fast Repair, Reasonable Price, Friendly and Professional. My tenant texted me that the hot water heater "was busted" and had sprayed water all over the garage. I called all the plumbers on my contact sheet: the first one couldn't come out until the next week, the second never returned my voicemail, and the third was an auto-reply re-directing me to other services in the area. Then I called Sergio. He responded to the voicemail within a half hour, got the address from me and was at the house in another 15 minutes. He quickly diagnosed the problem (not the hot water heater, but the supply line) and made the repair. Sergio's plumbing has now moved to the top of my contact sheet. read more

We had gone through several plumbers before I came back to Sergio. I had left a message for an estimate but did not hear back so I hired another agency. My mistake! The other plumbers/agencies did not meet up to expectations. And after a week of back and forth the plumbers that did not know how to tackle the problem, we called and explained what was going on. Sergio came, advised us of what needed to be done, gave us an estimate and he and his team got to work! Job well done!! Sergio knows plumbing. I plan to have him take care of all my plumbing needs in the future. I will gladly recommend him to my friends and associates. read more

Okay guys, I've had a leaking bath tub faucet for almost a week. It's the day after New Year's and I had an appointment with a well known plumbing company. They cancelled! Soooooooh glad they did. Sergios plumbing came through big time. Straight forward talk over the phone. I shot the owner a picture text of the issue and he quoted me a price?!!! No unexpected shenanigans when the contractor arrived 45 minutes later and as promised. They even fixed my kitchen facucet...Sergios Plumbing is the go to resource for anyone searching to align themselves with an establishment that offers red carpet services on a shoe string budget. read more

I called Sergio's Plumbing when my kitchen sink backed up he was able to come and fix it same day! My husband met him and liked him very much he even gave him a quick tip if it happened again. It was quick and beyond reasonable pricing I will call again and recommend him to family and friends!! read more

I was in need of getting my water heater replaced.. i did my research and called around town to get quotes... i went with Sergio based on his yelp reviews and after talking on the phone with him..He's very knowledgeable and competent in his skill. Sergio's plumbing did a great job. They were able to see me the same day. They gave me a fair price and it only took a couple of hours. I would use their services again for any plumbing issues. He constantly kept communication with me either through phone or text. Very pleasant and professional. I would recommend him . read more

Sergio responded to my request and made an appointment for the estimate. On the day of the appointment, he did not show up or call to let me know he was not coming. NOT reliable!! read more

I called to ask for a quote, but got a voicemail. Left a voice mail and got a text about what issues I am having the day after. It was pretty awesome to get a text instead since I prefer it. Sergio asked for a picture of the problems I was having. Sent two picks of my shower handles and that It was having a slow leak wasting water we were able to make an appointment today between 9a-10a and the cost is $280. Sergio came about 9:30am and got it taken care of around 10:30ish. He was very professional, nice to talk to, and was efficient in his job. read more

I had a great experience with Sergio's Plumbng. We had a large increase in our water bill indicating a leak. I got a referral to Sergio. I was able to reach him but he was on another job. Through a series of calls and text messages, he diagnosed that the leak was in our irrigation system. He told me that this was good news and a gardener should be able to help us. Ultimately he did not charge us anything. I definitely would use Sergio again. read more

Frustrated from calling several plumbing companies and getting the run-around I turned to YELP. After reading many reviews on YELP for Sergio's Plumbing company, I took a chance and called. After explaining the plumbing issue on the phone, Sergio knew right away the problem and how to fix it. Despite an already busy schedule Sergio and his staff came to my home and fixed the leaking shower faucet and the rest is history. If you want a professional, Sergio is your guy. His prices are reasonable compared to the overinflated quotes given by others. Thank you again Sergio, much appreciated and God bless. read more

I wasted several days without hot water trying to work it out on the warranty. Out of frustration I called Sergio and within a couple hours I had hot water again. He was courteous, friendly, professional, and reasonable. Most importantly, I got the results I needed, fast. I will call Sergio next time I need a plumber. read more

Ulandis with Sergio's Plumbing is absolutely amazing!!! Extremely profession friendly service. I really can't say enough great things. Fixed my clogged tub and sink in about 1/2 hour. My bathroom sick has been draining really slow for years and I asked him to please check it out after he was finished fixing the tub and wow!!! I couldn't be happier. Thank you again Ulandis and Sergio's Plumbing! read more

Great plumber and gave great advice. I've been having problems with a slow or clogged drain off the kitchen sink since I bought my house. It's an older house from the 40's. Sergio recommended a full cleaning and not just a snake and the results are amazing. If you saw the stuff (and the smell) that came out of that drain, you would immediately understand the problems I had. After the cleaning, I ran the water for several minutes and not a hint of clog or slow drain. He arrived timely and his prices were reasonable. I highly recommend. read more

Sergio and his guys are awesome. They unclogged my kitchen sink in no time for a fraction of the price other plumbing companies quoted me. They are super friendly and honest. I will definitely use them again in the future. read more

I've used Sergio's services before to install a garbage disposal and was very satisfied so when I had several things that needed work (water pressure, leaky faucets, running toilet, low water pressure, and a water heater issue) I contacted him again. Sergio responds within an hour and usually more quickly when contacted through Yelp and I was able to talk to him directly when I first called to inquire about his availability. It's been a week and everything is now in good working order. read more

I needed professional plumbing service on my kitchen faucet. After identifying Sergio as one of the top plumbers in Vallejo on Yelp, I gave him a call and left a message. He returned my call the next morning, and arranged a same day appointment. He reviewed the work, provided me with a fair estimate and repaired my faucet within 20 minutes. He was professional, prompt, competent, explained everything clearly. I was very satisfied with the outcome and will call him first when I need a plumber again. Thanks Sergio! read more

Sergio knows plumbing! He was able to come within 24hrs, explained every single problem and what he'd do to fix it, and even accommodated my children's naptime so he wouldn't wake them while he worked. You won't find better pricing, either. Sergio is the only one we'll be using from here on out! read more

Sergio was great when my main water line broke. He came and assessed it the day of within 2 hrs and knew exactly what was wrong. He was very meticulous and fixed everything while explaining what was wrong the whole time! Great plumber would highly recommend. Fair pricing and very professional! Thank you! read more

Believe Sergio's FIVE Star reviews! I initially called another plumber who had raving reviews on Yelp as well, but I never heard back from him. That turned out to be the greatest thing or else I would've never found Sergio. The communication was smooth, straightforward, and price was I believe very reasonable. I didn't even bother to look anywhere else as Sergio's service was impeccable right from the start. The 1.5" leak was underground and was professionally detected by a leak detector per Sergio's recommendation. Our stamped concrete had to be jack hammered. Sergio explained the process before he did the work and provided options and suggestions. I wasn't home when he did the work, and he sent me a picture of the damaged pipe. I truly felt he cared about me as a customer. He even asked if our city offers a Water Leak credit after the work was done. He takes credit cards, but we paid cash to get a discount. He also offers warranty for his work. I'm so happy to have found my go to plumber. I will for sure send business his way! read more

I called Sergio's because I thought I has a problem with my water heater. Sergio talked to me for a while and it turned out I didn't have a problem after all, it was acting normally. I like the fact that he took the time to explain things to me and told me not to waste money on a useless trip. He sounded very knowledgeable and he is definitely the person I will call next time I have a plumbing issue (and they seem to come up about once a year). I like having a person I can trust to do repairs right and not charge for unnecessary services. read more

Sergio is great! Honest, professional and knows what he is doing. I own an apartment complex and Sergio is our "go to guy" for all our plumbing needs. It was the holiday season and Sergio was fully booked. We were forced to use another plumber for a blocked sewer pipe. We had two plumbers out. Both gave us crazy suggestions for fixing the problem including just replacing the toilet and a broken pipe. We knew it was a blockage and was able to wait and to find a free slot for one of Sergio's guys. Fixed! Of course it was a blockage. He is the guy! read more

Sergio was responsive immediately, and extremely honest and professional!! Integrity goes a long way for any business to be successful. Excellent work and free advice along the way to boot! Thank you for a job well done!!! read more

My shower had a completely clogged drain. I called Sergio in the afternoon, he came the next morning (this was not an emergency since there is another shower in the house), and he had the clog out in just a few minutes. He was professional, kept me updated about when he would arrive, and was so pleasant to work with. I would recommend him without any reservations and will continue to call him with any problems that arise. read more

I sent an email from Yelp to Sergio's plumbing. Did not respond 24 hours. Phoned him the next day, told him my problem with the toilet. He replied, "What is your address & phone number, no I have your phone number, I will call you in about 2 hours". 72 hours later no phone call. This complaint is not about Sergio's work it is about the lack of professional courtesy. Thomas Williams read more

Sergio has saved me twice this month! Once a burst pipe that had to be rerouted, and next with a GE water heater that went kaput! I called up Sergio, and someone came out that day to assess the need. With the pipe, he came out the next day, repaired it, sent me video of what was done...voila! With the water heater, they purchased, delivered, installed, and hauled away the old one, the day I called. In the past Sergio has also assisted my neighbor with various plumbing issues. We love, love Sergio's Plumbing, so glad we found them! read more

I had a watermain leak and Sergio came to the rescue. After promptly returning my phone call, he immediately made arrangements to come out and give me a free estimate. He identified the problem and walked me through how he knew it was a water main leak. He patiently explained the problem and how he was going to fix it. He also told me to call around and get other estimates. He assured me I wouldn't get any better estimates. He was right. I called him back and he was out the next day to repair the leak. Him and his crew showed up on time and got right to work. I was taken aback how everyone stopped work and introduced themselves when I came on site since I have only spoken to Sergio on the phone. Very polite crew! They finished the same day and cleaned up the area. Sergio also provided me information how to get a rebate with the Vallejo water company for the leak. I saved a great deal! Thank you Sergio and team! I have you guys on speed dial for future plumbing needs. read more

Sergio is the best plumber I have ever met and I have been around a long time - 71 years. He is professional, courteous, punctual, honest and a man of his word. He did 4 jobs for me in 2 weeks, 3 in a rental I own with lots of water damage and a bad valve dripping in my MBR shower that was driving my wife and I crazy. He is quick to answer and if he is really busy, he will get back to you, as quickly as he can. And he has a great team of young plumbers that are equally as good as Sergio. Sergio could not do one job, so he sent Pedro and he replaced a bad shower drain and trap. Sergio and his team work fast and will not leave the job site without thoroughly testing everything and making sure you are satisfied. Sergio and his team always clean up, after finishing the job and it's like they were never there. He is my plumber forever and I enjoyed working with him and his team. Thank you, Sergio, you are the best!! read more

I called Sergio to see if he could get my toilet unplugged. He said that he could come and see what the issue was within 20 mins of my call. He already knew what it might be on the phone. :) That was fantastic. Soon as he came he was very knowledgeable and very honest from the beginning. He gave me two quotes both were very reasonable; really reasonable. I end up paying very very low price; I was so happy because so many other business wanted to charge so much for the same thing. I am so happy that my toilet was fixed and it was done fast. Sergio is very professional, hardworking, and most of all honest. That's exactly what I was looking for; I will always call Sergio if I have any plumbing issues and I will refer my friends as well. Thank you so much Sergio you did a great job, and I appreciate you! This was also done on my b-day today and he made my b-day not stressful but a wonderful one! Thanks....................... read more
