I can't say enough about GS custom plumbing! Gene is amazing and so very knowledgeable! Sarah, the office assistant is right on things all of the time! So thankful these two are local in Sherman Oaks. Thanks for the great service above and beyond! L. Hobbs read more

So happy to find an amazing plumber. Gene and his crew were amazing. Twice they have come out to my very old rental property to fix issues. They are very efficient and easy to work with. The crew are clean and friendly as well. I definitely recommend GS Custom Plumbing to everyone read more

Gene and his team provided exceptional service at a fair price. Gene went above and beyond, even stopping in when the Gas Co arrived to make sure everything was copacetic. It's rare these days to find someone who goes the extra mile to make sure their customers are completely satisfied, and with Gene and GS plumbing - you've found your new plumber for life! read more

Gene and his team installed a new Toto washlet+ toilet flawlessly in my home with great expertise for a fair price. They were professional and friendly and knowledgeable and I would definitely recommend. Scheduling was also a pleasure as the office is well run and extremely responsive. read more

Gene is delightful. I've dealt with many other plumbers in the past, but none have been as knowledgable and as efficient as him. From having an emergency and bursting my pipe to upgrading my shower head, you can tell how great he is at his work. He's punctual and when I had my pipe burst, he was able to show up quickly. My upgraded shower is WONDERFUL! He lifted my shower head, put a filter on it and installed a rain shower head! Will only be using him from now on. read more

Amazing plumbers! They were on time! They completed the job perfectly and were very nice on top of it! They also cleaned up the area really well. I would recommend GS Custom Plumbing in a heartbeat!!! read more

I called 2 other plumbing/rooter companies before them and I left all three of them voicemails. Robert got backed to me and it was 9am in the morning. He said he could get to my house at 10a. I wasn't home but my aunt was and by the time I came in, Robert and Gene were inspecting the problem and insuring us that they had a snake that is 200 ft long. They both took care of the problem. They used their GoPro camera and showed us the problem before taking out the ton of "flushable" ass wipes that never dissolved in our sewer tank. Then of course some feminine products. Other than that, we paid a great deal for problem getting fixed, great customer service, immediate service, knowledge and skills, and not to mention 2 hot guys. Lol what can I say, I'm a single woman & I'm very much entitled to look. Hello!! Thank you so much GS. I will definitely be calling again if i have plumbing issues and I'll definitely recommend you to family and friends. read more

I wanted to write a review and THANK Alfonso and Custom Plumbing so much for saving my daughter and I today in Studio City. GS Custom plumbing was doing work for our neighbors next door in our condo unit in and my daughter and I got locked out of our house with our dog and Alfonso was sooo professional and kind to let us borrow the company phone and his own cell phone to track down a locksmith. All the while he was efficiently working hard next door while checking up on us and trusting us with his phone. Super kind and professional humans work here and I will use them as plumbers forever now, and just in time...because I was in need of one and now know where to call! God bless! read more

Earlier this month. our toilet started overflowing. Gross. So we called GS Custom Plumbing (after seeing an ad on Yelp), and Gene came over later that afternoon. We asked for him to clear the clog & to see what was the problem using a camera. Turns out, roots were growing into one of the pipes. Did you know roots could do that? I did not. He fixed the clog and gave us recommendations on how to fix the pipe. THEN the next day, our laundry room had water on the floor. Another pipe? Turns out the pipes we had under our house had been installed improperly. Call GS Plumbing! We did, and they helped us figure out the problem and suggested improvements Would totally recommend GS plumbing to everyone. Gene is super friendly and his crew is very professional. They want to do the best job they can, and are helpful in every way. read more

Gene & his crew are amazing. professional, experts, trustworthy, on time, fast, efficient and neat! they go the extra mile. i recommend this company to everyone. they have done everything from installing a new showerhead to installing a new hot water heater. and everything in between. thanks gene!! read more

GS CUSTOM PLUMBING was prompt in responding to our call. We had a leak under one of our bathroom sinks, and needed some overdue plumbing maintenance as well. Gene the owner came out when he said he would...very prompt with our agreed appointment time! When he arrived he had on a mask, shoe covers, and followed all Covid safety guidelines. This really helped put my elderly mother's mind at ease! Gene was honest, friendly, very knowledgeable and professional. During his visit he explained everything that needed to be done and then he stated that his assistant Sarah would follow up with an itemized written estimate/invoice via email to make it easier for us to understand what needed to be done, which we loved. Now to Sarah... she is amazing, a great communicator by phone, text, or email, which ever we preferred. Her attention to detail A+ and her follow through skills are excellent. Overall...we would definitely call GS CUSTOM PLUMBING out again... we highly recommend them...best experience we have ever had with a plumbing company! Thank you Gene, Thank you Sarah! read more

I wanted to update my review, because we have continued to use Gene and his plumbing team for multiple issues with our house! They always take their time and explain what and why they're doing what they're doing, so we always feel taken care of. Since my last review, they have fixed our toilet base, unclogged our bathroom sinks, our shower, replaced our under sink hot water heater, fixed our garbage disposal and just generally given us great advice to keep things running smoothly! Thanks Gene! read more

I can't say enough good things about this company! Gene and his team are on it! These guys are neat and clean in their work! Work super hard and get the job done! My go to company and first recommendation if someone asks me if I know a good plumber and by the way people always ask this! read more

Shame on you! You made me send you photos of my water heater(s) over the phone and you said i needed to replace both my water heaters! Even though I mentioned one water heater was only 3 years old! Obviously you did not want to come to a small job which is fine but tell me that and don't lie by telling me to buy new water heaters over the phone! As a business owner I get pick and choose your customers we do it all the time but honesty is key.......After calling a trustworthy plumber he fixed both my water heater issues in 10 minutes and guess what no new water heater are needed! DO not trust this team who makes recommendations over the phone without properly diagnosing the problem- i see them all over my neighborhood and I will advise my neighbors. read more

Our experience with GS Custom Plumbing actually started out pretty good. Our kitchen sink and master shower became clogged over the weekend so we looked for highly rated plumbers on Yelp. GS was the first one to respond on Monday morning. They came out and unclogged the kitchen sink - there was some kind of sludge that looked like coffee grounds clogging up the line. The fee was reasonable and we even recommended GS to our neighbors who had a similar problem (we live in an older condo building). Here's where things started to go south: shortly afterwards, our toilet in the half bath near the kitchen became clogged up. We're not entirely sure what GS did with the sludge that they removed from our kitchen sink - did they try to flush it down the toilet? We don't remember them taking out bags of any waste. All of the dirty standing water from the sink was flushed down this toilet, so i My husband called them and left a message asking about this. We wanted to find out what had happened and have them come back out and take a look. No response. We called them three times - two of these times it didn't even go to voicemail. He sent an email. No response. He also messaged them through their website contact form. Still nothing. We asked our neighbors if they'd tried calling GS - they had and also received no response. Our advice would be to steer clear - GS Custom Plumbing might help you initially, but they lack follow through. Update 4/30/18: We had a different plumbing service come out to fix the clogged toilet. They found a washer/kitchen nut from the kitchen sink that was clogging the toilet. It's now pretty clear that the clogged toilet was the fault of GS. They fixed one problem, but caused another. read more

Gene is the BEST of the best! I read all of the rave reviews before hiring GS, and I was STILL blown away. Gene is a friendly, outgoing professional with a great sense of humor. He & his assistant, Robert, juggled their schedule to get here, helped me find a great solution for installing my new washer/dryer combo, & got to work immediately. It makes me tear up a little bit when I meet professionals who obviously know their stuff & take pride in their work -- It's so rare. Call GS if you're a big fan of expert workmanship! read more

My go-to guy for plumbing needs. When my wife and I were moving into our new house we decided to change out an electric stove top with gas. Having done gas lines before I took the job on myself but ran into a problem where, after rehooking everything, I kept hearing a leak. I was running out of time and patience so I called in GS and they came out and fixed it in no time (one of the tubes had a hole). A few days later I called Gene again about coming out to hook up my water line to my fridge. He commented that he saw the work I had done on the gas and proceeded to give me a pep-talk on being able to do this myself and save the money. Kind of funny when you think about it. But it shows what kind of a guy that he is that he did not just take my money but instead encouraged me to do the work myself and how to do it. Sure enough, he was right. His card is pinned to my fridge for when the day comes that I will need him again. read more

LOVE THIS GUY. But let me go back a bit. We had a total backup in our main sewer line. We had tried snaking it ourselves, but the rental unit only went 100 feet. And seriously, it was NOT something I would want to do again. It was a Sunday, and I just wanted it fixed. We couldn't flush the toilets or run any water. So it was a bit of an emergency. We called Mike Diamond because they are well known. A MISTAKE. That dude was so useless it was nothing but a waste of our time. I came to my senses and yelped "Sherman Oaks Plumber" and Gene was the first name that came up. I called him, but it was late on a Sunday, so he came out at around 8:45am the next morning. 15 minutes early by the way. He fixed the problem, ran a camera, and installed a clean out for us all for less than $1000. Mike Diamond had quoted us $5000 and didn't do ANYTHING. Gene is the man. Also, my dad was instantly "buddies" with him. We will call Gene again for ALL plumbing issue we have. I suggest you save yourself the headache of dealing with anyone else and call him too. Definitely don't call the idiots at Mike Diamond. The reason they "Smell good" is because they don't do shit. Literally. read more

GS was responsive to our initial call when we had a water leak. The reason for the 3-stars is due to a couple things. We had our water heater turned off because of the leak. When GS left, we didn't really test the water and check if hot water was coming. Then overnight found out hot water wasn't on. It wasn't until I consulted another engineer in our building that we pinpointed the heater was not turned back on. This was a small thing but part of making sure everything is in order. 2nd visit We were happy with the service so we called GS back for maintenance work. I am not exactly 100% satisfied with the shower head maintenance and caulking in the kitchen. I will call them back and see if we can address it. We have plans for additional work too. Price wise, I would not say that you always feel good after getting the bill. read more

GS Custom Plumbing is my guy for all my plumbing needs. They are Really Knowledgeable, Trustworthy and Dependable. I can't recommend him enough. His service is top notch. Highly Highly recommend read more

I love dealing with people that have 5 star ratings here on Yelp and Gene is no exception. He called back quickly after I left a message early on Thanksgiving eve, talked me off the ledge (I had a broken water main and was having 10 people over for Thanksgiving the next day). I texted him a few photos of the pipe and a little while later he arrived with all the tools and materials needed to replace the 50 year old , 60' galvanized pipe. Gene and his crew are personable and professional and I would gladly and highly recommend him to anyone without hesitation. His priced seemed fair and reasonable and did not at all seem "seasonally adjusted". If anything, it was probably less than others would have charged, given the circumstances. Thanks again Gene. read more

I have known Gene and used GS Custom Plumbing for years. He is not only dependable and professional but has prices that are competitive and in line with the work that is being done. Without hesitation I would suggest and recommend Gene and GS Custom Plumbing for any of your plumbing needs. read more

Professional, attentive and performs high quality work. Came out to my house on a weekend (3 times) and honored his original quote. Used high quality long life parts so that I don't have the same problem again. I would recommend to my Mother. read more

Gene is an absolute stand up professional. I called him the day after Christmas to check out a preventative water main issue that was related to an emergency service which I already had under way. He called me back immediately and went to the site only a few hours later. Another plumber suggested a $6,000 fix but Gene honestly let me know that nothing needed to be performed. I greatly appreciate his honest opinion and I will absolutely use him again in the future. My issue was for a large apartment building. read more

Gene was able to troubleshoot over the phone, saved an emergency situation, and saved us lots of $$$. On the next job, GS Custom Plumbing will be our first call! read more

A+. So I had a sewer line back up at my house. Not fun, and worse got some expensive quotes from my go-to guys. People came out, poked around, and were quoting me wholesale replacement of my sewer line. I really felt uncomfortable with the numbers coming back, so I found GS off of this very site. Gene was awesome, showed me the problem, what he knew and didn't know at that point, which with a sewer blockage is part of the problem, got me to a livable state, then for the major repair he gave me a fair price, and knocked out the repair in a day, just like he said he would. I appreciated him showing me at different stages what he was looking at and my options for repair. I have had the experience in the past of sitting around sweating, wondering what the total was going to look like. He didn't mind me being nosy and checking out the work from time to time, and his crew was as friendly and honest. Overall, very glad I called him, and would recommend him to anyone. read more

I am updating my review of GS because I simply can't say enough about these guys. I've been having plumbing issues in my home since I moved into the house three years ago and only now through the help of Gene and his team of pros are these issues finally resolved. As usual, they were prompt, clean and courteous and their work is impeccable. Cannot speak highly enough! It's such a relief to know there's a safe, reliable plumber in the area and we'll absolutely be going to these guys for all our plumbing needs in the future. read more

We had an emergency that need to be addressed within 24 hours and they came through. These guys are the best. Great work, fair price and totally reliable. Can't recommend them highly enough! read more

Gene came to my house to fix my showers Incredibly personable and informative, my shower pressure was awful before Gene came and fixed both of them this morning. I ended up spending far less money than I planned on. Super nice guy and very professional, couldn't recommend him more. Thanks Gene! William read more

Worst customer service ever. They will jerk you around reschedule on their time, not make good on their commitments and then when they change the time yet again, and yet again not honor the scheduled appointment time that THEY set, they'll act like you're the problem. Do not use them if you value your time. read more

DON'T USE THEM. They said in writing "It's 175 installed not including water lines or any other materials for the regular faucet if you would like the Kohler sensate installed that price is 275 installed" Then they tried to charge me $1,300 and we settled on $1,000. IN OTHER WORDS, BAIT AND SWITCH. Prior to that, they installed a new hot water heater and reworked the piping. They told me that there was a one-year warranty on their labor and materials. I now find that a part of that work was defective and they have refused to honor that warranty. They want me to pay for fixing their defective work THEY DON'T HONOR THEIR WARRANTY. I am entering a complaint with the California Plumbing Licensing Commission. read more

Gene and his guys have been my plumber for 6 years now. And in that time, I've had nothing but the most efficient, courteous, and professional service from them. I've made upgrades that I'm very happy with in these last 6 years: a tankless water heater, touchless swan neck kitchen faucet, new pipes in the garage (installed after another plumbing company failed at their job and insisted that I replace all pipes when I only needed a small vital section to be replaced), and a hydro jetting that was a long time coming. After all this time, I know I can always count on Gene, he's very passionate about his work, and always provides the best service possible. read more

Best plumbing company in Los Angeles. I refer them to all my clients without question. Gene is very responsive. He will always be the first plumber to come out of my mouth! read more

I have used GS Custom Plumbing services twice when I returned from two trips with a different plumbing emergency awaiting me each time. The first time was a pipe that had burst in the garden with a geyser of water coming out forcefully everywhere. Gene of GS Custom Plumbing came right away, was able to stop the leak and then send his team that afternoon to cap the leaking pipes. Given the amount of work, and their amazing speed of response, their bill was pretty reasonable. The second time that I came back from a trip, I found that the glass vessel sink in my airbnb guest bathroom was leaking considerably, and GS Custom Plumbing assessed that the leak could not be fixed and that I needed a new sink. I ordered, but it arrived with the wrong faucet, so they came out a second time when the correct faucet arrived and they were able to install that part. Ultimately because they were unable to complete the full sink installation, and that cost me money as I was unable to rent out the room for a few days, they were kindly professional as to not charge me for the job, which I VERY much appreciated! Gene and his GS Custom Plumbing team are professional, always have a great attitude to do their best, and very courteous guys to work with! Thank you! read more

As an attorney, I'm generally distrusting of vendors. However, Gene and his company have been incredibly responsive, professional and competent in my dealings with them. I recently had a sound going off (after work hours) in one of my toilets and gene personally walked me through sending him pictures and calling him over and over until he helped trouble shoot the problem until it was resolved. He's a good guy and wants to take care of people and i just wish there were more company's like this. read more

A long overdue review for this AMAZING company. I am an avid reader of reviews, but seldom write any, unless something impresses me as truly awful or superb. GS obviously falls into the latter category. We recently moved into a new (old) house, and there were a number of small plumbing issues I needed to have checked out. The previous owner told me that another company had done all the plumbing work for the house, but when I looked them up on Yelp, their reviews were horrible. So, I decided to give GS a try based on the great Yelp reviews. One of the best house-decisions I have made thus far. Gene and his assistant came over the next day (they offered to come over the same day I called, but I wasn't available). They were super-polite and professional, and they arrived on time (something I am very particular about). They also happily took off their shoes before coming into the house (house rules & something that some vendors have issues with). I asked for what I called a plumbing "tune-up" for the house. Gene spent about an hour and a half at the house, fixing a number of things (a valve that had been improperly installed, faucets, tubs, toilets, etc.). He also told me what needed to be fixed right away, and what could wait -- something I really appreciated, given the number of things we have had to have fixed immediately upon moving in. He even fixed things I hadn't asked him about -- like an annoying loose handle on our master bath walk-in shower, which my husband had been unable to tighten despite his best efforts. I could on and on, but the short of it is, give Gene a call. He's competent, professional, polite, reasonably priced and an overall nice guy. read more

A nice guy who is a wonderful plumber -- honest, fairly priced, arrives on time, and does what he promises!

Called GS Plumbing for a few separate issues in my place. Gene was on-time and was extremely thorough in his work. Gene gave excellent recommendations and allowed me to make the decision of what would work best based on the assessment. I highly recommend GS Custom and will use for all my future plumbing needs. read more

My first review on Yelp ever. Gene is the most high tech plumber I've ever met. He has all the best equipment, knows his trade (it's in his blood for generations), and is straight up. What else do you want in a plumber? read more

Had busted sprinkler pipe so I called and left a voicemail, pretty late around 9.30pm. Before I even finished leaving the message he called back. Came by the following morning on the dot 7am. Punctual!! Price was fair. He offered free follow up inspection too! Gene hooked it up!! read more
