Toan, is the most honest professional I have ever encountered. I had a problem with water pressure, he walked me through it, and fixed the problem over the phone. Other companies would have charged me just to come take a look.I'm glad my Son highly recommended him to me. I will always call on Toan for future services. read more

Toan is fantastic! Installed 2 toilets and a new faucet. He came highly recommended from my realtor and also from a friend. He communicated with me about everything. Appointment was scheduled for 7 am, and he was on time and ready to work. The quality of his work is top notch, and reasonably priced. He caught an issue that the inspector missed. I will definitely use him again! read more

Twan did a great job on my main water line, coming into the house. He was able to correct a previous bypass copper pipe route line. Our house used to have a water softener, that we never used. The main water line is back connected as it was designed. I requested the garden hose spicket, before the house regulator. Twan told me, he would try his best and he did. Awesome!!! A new 1/4 quarter shut off valve was installed, prior to the new water regulator. Another new 1/4 quarter shut off valve for the backyard, before the house line. I now can turn the main water line off to house and still have water to the backyard. So Kool! Thank you All Star Plumbing (Twan and office staff)!!! Highly recommend!!! 5 Stars!!! read more

I requested service, he cane a couple days later. The value was good. And I would definitely recommend. Good guy.

4/9/2026... I am very impressed and happy with Toan's work. He was very clear about the cost of installing a new hot water heater. It didn't take long about 2 hours or so. He answered the questions that I had, explained everything he was going to do and proceeded with the installation. I will be calling on his services for other plumbing jobs that I may have in the future. read more

Highly recommend All Star Plumbing for any plumbing needs. In the past, I've dealt with a few dishonest plumbers who tried to balloon the price with unnecessary upsells and inflated quotes. I recently had an issue with my shower that was driving me crazy--no hot water, weird pressure. Toan(Owner/Tech) responded asap and immediately got to work diagnosing the problem. He explained everything clearly--what was wrong, why it was happening, and the best fix--without any upsell pressure or attempts to overcharge. He had the parts on hand, worked efficiently, and cleaned up everything perfectly afterward. No mess, no damage to the bathroom, and the shower works better than it has in years--great pressure and consistent hot water! In my experience where some plumbers try to take advantage, it's refreshing to find an honest business that I can truly count on. I felt like I was dealing with a true pro who genuinely cares about doing the job right and treating customers fairly. I'll definitely be calling them for any plumbing needs and sending friends their way! Thank you so much for the excellent service! read more

As legend goes, Toan really is the man! Knowledgeable, reliable and friendly. No bs kind of guy with affordable rates. I hope we don't need any plumbing work done any time soon... but if we do, he is the only one I'd call! read more

I, too, was referred by a neighbor, who has used them for a long time. Great, fast communication. They even moved my appointment up a day. Toan is a very knowledgeable and personable technician. I'll definitely use them again if the need arises. Highly recommend. read more

I was referred to Toan ( All Star ) by a friend. That's how you know it's a legit small business owner when he backs his word every time. I've had him do repairs at my business bringing in a new water heater and bringing up to code and also at my home. He's punctual, doesn't mess around and is respectful of your property. It's nice to know there are still honest service businesses out there who actually care and have great pricing as well. Just an all around great experience every time! read more

All Star Plumbing - Brand new Kohler toilet installed ! - Plumbing Near Me - Fairfield, California

Toan is THE MAN. All these 5-star reviews are spot on and well deserved.

His suggestions have been practical and his pricing very reasonable when I looked at other options. On top of all these superlatives, Toan is just genuinely a nice guy and a pleasure to be around. Thank you Toan for what you do, and we wish you the best!! read more

I discovered my water heater was leaking and contacted my home warranty to get it repaired or replaced. They sent George James of All & All Plumbing out of Sacramento. Don't ever work with this guy. He barely assessed the issue but still took $85 cash from me, and I never saw him again. I then had to find someone myself and was referred to Twan of All Star Plumbing out of Fairfield. After my first experience, I realized I needed to do my research before giving any more money away. Lowe's, without assessing my unit, quoted $2800 to install an A.O. Smith 12 year 50gal, 40BTU unit. Bell Bros did a full inspection and quoted $4500 with a standard 1 year warranty to install their 6 year unit or $5500 to so the same but add 10 year labor and parts warranty. I called Adam's Plumbing out of Vacaville, but they never returned my call (never). I finally decided I'd go with All Star. I read nothing, and I mean nothing, but great reviews from countless customers over years of service. I told Twan my exact issue, and he quoted $2100. I wasn't crazy about spending that much, but some would be reimbursed through my home warranty, and I was leaking about a gallon of water every day, so I decided he was my guy. I could tell before he even finished that he was a pro at this work, and when he was done, I had a beautiful new unit installed. Twan is meticulous, knowledgeable, friendly, fast, clean, and professional. I've had all kinds of work done on my home, and there's always some kind of mess left for me to clean up. He picked everything. Even as he soldered, he was conscientious about not letting liquid metal drip or splatter on anything in my garage. When all was done, I had a beautifully installed new Rheem Professional replacing my old unit. Twan stands behind his work. I have a 6 year parts and labor warranty backing it, and, as far as I'm concerned, I got just as good a unit and service as I would have with Bell Bros for nearly $2500 less the cost. Twan and All Star Plumbing are top-notch and the only plumbing service I'll be using from now on. read more

Twan is great! Very hand-on. Very informative on what he's doing. All around the best. He got the clog fixed after two other plumbers failed to fix it. It was a clogged toilet that would also over flow and leak every time you used the laundry or other bathroom. He explained it was the sewer line and he was on a mission looking for it. Highly highly recommend! Will not go to anyone else ever again. read more

Toan was professional, explained everything very well. Fixed both my plumbing issues used. Highly recommend!

I found Toan through all the great online reviews and they were well deserved.. He does no advertising so is a little hard to find, but the search was well worth it. As his card says he gives free phone estimates and very few businesses do that anymore. I needed a toilet install + some bathtub grab bars. He advised me what products I could purchase myself and gave me an estimate for the install. This saved me money from the start and then his quoted labor prices were very reasonable. Toan arrived right on time and completed the work quickly and expertly. He took a few minutes to explain proper operation and maintenance .He even had time play a bit with our dog ! Just a very nice man doing great work at reasonable prices read more

Toan is the best; hands down. I only trust our plumbing needs with All Star Plumbing! Amazing service and value.

As a lifelong resident of Fairfield, Firefighter of 20+ years, & homeowner I value good service... It's more rare than common these days. Toan is one of the rarest, and is a pro at his craft. He will never upsell or up-charge. He doesn't need to advertise because his referrals from happy customers are endless. If you value honesty & integrity, I'd highly recommend you call All Star Plumbing. read more

Thank you Toan! Found Toan and All Star Plumbing through recommendations from neighbors and I was not disappointed. Our water heater stopped producing hot water and the light was indicating a failed burner unit. I got multiple estimates from places with prices ranging from $400-800 to replace my supplied part; others quoted me just to replace the unit without repairing. Those prices ranged up to $3200. Toan came out the very next day (earlier than expected) and fixed my burner unit quick and easy for a fraction of the price I was quoted by other companies. I appreciate his honesty, thoroughness, and explanation of things. He is our go to guy & I will refer him to everyone. read more

We called several plumbing services through yelp that claimed to have 5 star rating none replied back as quickly as Toan. Budget plumbing quoted us $500+ to do the job but never called us back to confirm the apt which was a blessing because we would never had found Toan. I knew Toan was the guy when he took his shoes off to come into my house. Not only he is respectful, affordable but so down to earth and funny. I highly recommend him for your future plumbing services. Thank you Toan! read more

I hired All Star Plumbing to install a new water heater and I was very happy with their service. Tuan gave me a reasonable estimate and came out the next day . He was on time and did a great job. I would definitely recommend All Star Plumbing! read more

Horrible experience with Twan, the owner. Rude and inconsiderate. Couldn't tell you the quality of work due to not getting that far. Called today and left a voicemail detailing that it was kitchen sink related and that we'd need whomever comes to wear a mask due to health related matters within the home. He called back later today and he said he could come on Thursday. He asked what was going to be worked on and I explained what happened with the kitchen sink. After setting up the time I just confirmed that whomever comes would need to wear a mask. I didn't even get to finish my sentence as he cut me off with a snarky tone "yeah I'm not wearing a mask in 100 degrees" to which I politely laughed and said no worries there it's only the kitchen sink and garbage disposal area. He replied "I'm not wearing a mask the order was lifted maybe you need to find someone else." I didn't even get to finish my initial sentence. Not that I should have to explain person health concerns to a business that would enter my home anyways. He was defensive and completely unprofessional in how he handled it. Maybe he does good work, but we will never know. read more

Toan is fair, honest, and responsive. He repaired my water heater instead of replacing it. Well-deserved rating.

Toan came highly recommended on various social media platforms so I just had to contact him to check out a leak coming from my upstairs bathroom into my downstairs bathroom. A quick check and he was able to assess the issue and resolve it. From start to finish, he explained the problem and the steps to fix it. He was quick, efficient and super friendly! I was expecting to confirm an appointment with him by the end of the week, but he was able to come the very next day after contacting him. I would definitely call him again for any plumbing needs. I agree that he is the real deal. Great and honest work! read more

Great service and honest. Told us up front what he would charge and got the job done correctly kitchen sink and gave 1 year labor warranty

We needed a leak fixed at our yoga studio. Turned out to be a cartridge. Toan (All Star) is our regular guy but he was not readily available because of the holiday and his much deserved break. Urgent to get our shower back in operation as we are a HOT yoga studio I called Oak. Long story short was adamantly quoted $1,800 and that a hole needed to be opened up in the wall.... Moved on, called Jovani, quoting $800-$1,600. Toan came out (during his time off), had the part (which he showed me was $67 on Amazon), replaced it and billed the landlord $180. Always, use a trusted source. read more

10/10 great experience. Toan is very well experienced and professional in what he does. After calling, Toan showed up promptly and immediately worked on solving the problem. He is very personable and honest. I highly recommend him and his services. Thanks Toan! read more

Toan was able to help install our new kitchen faucet and unclog our bathroom sink, providing us home maintenance tips as new homeowners along the way. He was the plumber that was the most responsive / first to respond when we called around for help. He was good at keeping us in the loop via text when he was going to arrive on the later end of the window of time that he originally provided. Incredibly helpful and highly recommended. He'll be the first one we call in the future. read more

Had a leaky faucet and rather than buying the parts and charging me, Toan directed me to Kohler to get the parts which they sent for free. Great customer service! Toan was professional, showed up when he said he would, explained all that needed to be done, and did a fantastic job. If you need someone reliable, professional and knowledgeable and don't want to be waiting around all day wondering if the contractor will show or not, call Toan, All Star Plumbing (Fairfield, not Napa!) read more

If you are looking for honesty, reliability and affordability Call Toan of Allstar Plumbing. I feel comfortable referring his business to everyone I know. read more

I'm so impressed with Toan. I had issues with my water heater and desperate to get it fixed. Five companies advised me to replace the heater and or was told that the heater is way too old and there's no available parts. I received 3 quotes. Toan offered the most reasonable price. The best part, Toan saw that he can fix the problem and replacement is not needed at this time. He gave me a warranty. He would have made more income by replacing the heater which I already agreed on. In addition, he was quick to give me a call back and he arrived at the property as scheduled. I highly recommend this guy. He's super honest, reliable and profession. Hard to find someone like him nowadays. He's amazing. read more

Toan Nguyen - professional! My wife called and scheduled the troubleshooting. We had a toilet and shower issue resolved in less than two hours. Excellent work! EDIT - so this week I took vacation and on Monday (the holiday) I came home to find water coming out of the garage, running under the garage door. I found the bottom of the hot water heater leaking...it was the original heater and it officially died. I called a few Plumbers and Toan had the best price. He ended up being available a day sooner than promised and he called saying so...I was home so I said go for it. The install is great, he cleaned up and hauled all the trash away. A+ as usual and very professional. read more

Toan is the bomb when it comes to plumbing needs. Always has a second to give you an estimate or trouble shoot your problem over the phone.

Did the small things that make him 5 stars. He is the best out of the last 3-4 plumbing companies I have tried.

Toan is very professional. He answered his phone and immediately considered when he could come to the house. He was at my home in a few hours. Problem resolved in minutes. The payment was easy via Venmo. My stress was up over my head and now I'm relieved and relaxed. He let me be aware on how to operate the toilet won't flushes efficiently and made me aware that the toilet is 34 yrs old. Yes time for a newer model, lol! I'm so grateful for finding Toan here in Yelp. You will be too. read more
