Number One by a mile in my book! 10 Stars! After our Noritz Tankless heater stopped working, I was looking for a repair person. I was blessed to meet Curtis at Watanabe plumbing! Curtis had one of his staff come out and check out our unit. He diagnosed the problem quickly and said he would order the parts needed. Curtis communicated during the whole process and kept me updated. Curtis (himself) came out and replace the offending parts. He got us up and running quickly. Cannot recommend this business, enough! I will not waste time and money on anyone else in the future. I highly recommend that this is the person you should call if you have a problem. Thank You Curtis and staff... read more

Curtis Watanabe Plumbing was excellent on their work. Had a Bosch dishwasher installed by him & his son with no issues. Also my Noritz tankless w/h repairs went smoothly. On time on scheduled appointments, cleanliness, knowledge & experience on their part. Curtis is great on returning phone calls with plumbing issues & services. Definitely worth recommending him & his crew for all your plumbing needs. read more

Curtis Watanabe Plumbing is the best! We've been living in the south bay for nearly fifty years and tried many plumbers. I'd say he's the best in terms of professionalism, technical know-how, efficiency, cleanliness, and communications. Highly recommend. Five stars! read more

I'm surprised by all the positive reviews - if I could give this zero starts I would. We hired him to fix a drain line issue, which we believe he did fine. Since the pipes are underneath the house, we don't really know if there's an ongoing issues. Since we can't see the pipes unless we crawl underneath the house. After he did our drain lines, we were having some weird issues with our supply lines so he recommended we replace our supply lines. He gave us a quote and it seemed like a good deal to get all new supply lines. First of all - we were under the impression we would get our copper supply lines replaced with new copper pipe. Instead, he installed pex. Admittedly, that's our fault because when we looked back at the contract it did mention PEX, but as non-plumbers we had no idea what that meant. To be honest, we didn't know that there were any other types of materials besides copper so we thought that's what we were getting. We wish Curtis could have walked us through it more to be more transparent. It felt a little sleazy. Whatever, it got the job done. However, in addition to the somewhat sleazy sales pitch. We've still been having issues years later with the work they did. The work damaged a lot of our walls which we had to repair ourselves. There were obviously leaks in their work because we noticed mold pop up in two separate parts of the house where they had worked. We had to have two separate plumbers come back to repair their work months later. Both of which commented how shoddy the previous work was. At the end of the job, When his workers were finished all they said was, "okay we're leaving" without showing us their work. We asked them to walk us through the work, where we found multiple leaks, and damages. We had to point them out, and only then did they hurriedly fix them. No wonder they didn't want to show us what they did... look at the quality of their work on these photos. To this day, I am constantly worried that there's a hidden issue under the house or behind the walls that we are yet to uncover. It's been months since they worked on our plumbing and we're still seeing issues pop up to this day. Never, ever will we ever hire them or recommend them to anyone. Worst job ever. read more

See all

Curtis was hired as a Sub to do the plumbing work at my new shop. Initially, they did a great job and had everything working perfectly. Fast forward a few years when I needed to fix a leak from my 3 compartment sink drain, it seemed like it was fixed but the leak continued after 2 weeks. I contacted Curtis right away for a follow-up fix through text. He said that he can fix it and would stop by. A few weeks went by, he never came. I follow-up again, he said he can come by the next day. He never contacted me or came by. This same experience happened numerous times, then made excuses that their vehicle was involved in 2 accidents. I'm sorry that happened, but if you're okay and you have employees, work should continue even if you have to rent a car/truck to keep your business running. I'm a business owner too, customers don't want to hear excuses or your sad stories, get the job done and take accountability or GTFO! He said that he would stop by the next day, which still hasn't happened after another 5 days, it's now been over 6 weeks! I was charged $500 in labor costs with no follow-up when their installation isn't corrected. In short, you're SOL if you have problems after the work is completed, they won't return. Now, I have to hire a different company to complete their work. This experience seems to be very consistent with every other 1 star review. Take a few mins before hiring them and read them for yourself. There's a lot of other companies out there that need/want business, clearly Curtis Watanabe Plumbing isn't one of them! BEWARE!!! I will never do business with them again! read more

This is the best plumbing company I've ever dealt with. They are efficient, punctual, and professional.

If you want to be sure that what you are told is the truth - Call Curtis! Had another company come out for service mostly because Curtis was busy BUT I should have been patient and waited for Curtis. The other company claimed I had a broken sewer pipe and they wanted thousands to fix it. Curtis came and ran his camera - snaked it out and what do you know no break no thousands to service! Honesty is the most important thing to me - you want to believe what you are told and you always get honesty from Curtis. Thanks for the great service every time! read more

We called Curtis Watanabe Plumbing based on a referral from another plumber. Our Noritz tankless water heater needed repair. We contacted Noritz and had the parts sent out (still under warranty). Vince came out to install the parts. He was very efficient and had the job completed and the heater programmed in just a few hours. Price was reasonable and Vince was very professional. Like others have indicated, call Curtis Watanabe Plumbing first. read more

Hot water heater he installed is taking 10 minutes to provide hot water in the morning. Ugh!!!!

Replaced a toilet quickly and properly: picked up exactly what we needed, removed old toilet and installed the new one, everything was cleaned up well. Employees all easy to work with, polite and efficient. read more

Call Curtis first! You'll be sorry (like I was) if you don't! My Noritz tankless water heater died and I was faced with an unhappy family. The first place I called came over and charged me $160 for "trouble shooting." They tried hard and were helpful in letting me know what parts they thought were needed but still no hot water. I picked up the parts myself but they weren't available to install so luckily I gave Curtis a call. Curtis was at my place in 10 minutes and knew exactly what part to replace. He actually carried them in his truck! 5 minutes later I had hot water again and his price was less than 1/2 of the other guy! In fact, I had to force him to take the money because at first he told me the other place charged me enough for both of them. Boy do I wish I had called Curtis first. Finding a good, honest, knowledgeable plumber is really hard so do yourself a favor and call Curtis if you are in need. Really great guy, he knows his stuff, and he's very reasonable and fair on prices. Outstanding! read more

Curtis Watanabe and his entire team are SUPERB. Over the years Curtis and his team have helped me with numerous tasks - a clogged washer line, replacing bathroom fixtures, and just recently replaced my water heater AND replaced the water line from the meter to my home. They were always on time, got me to laugh about the whole situation, explained everything thoroughly, and displayed a positive "can-do" attitude. It's delightful! And, yes! There's more! Curtis' rates are fair and reasonable. Really. I trust Curtis 100%. Call Curtis! You'll be happy as a plum (yep, I said it.) read more

On Sunday our Noritz tankless water heater stopped working. After speaking to Noritz, they overnighted parts under warranty (five stars for Noritz too). I reached out to a few authorized servicers, and Curtis had the best price and was willing to show up at a moment's notice. When the parts arrived I texted him and he was at our home in just a couple hours, and less than an hour later the work was done! He was courteous, professional, and very responsive. I think I've got a few more plumbing-related things around the house for Curtis to fix... read more

I called Curtis because I had an issue with my tankless water heater. He said the tankless heater needed to be replaced with an outdoor unit. After giving me a quote of $1900 the unit was replaced. I asked for a receipt for the unit, which I felt I was entitled to. He refused to give me a receipt for an item that I purchased, which made me suspicious. I asked how much the unit was and he said $1300. The total bill was $1900. Thinking that $600 was steep for replacing a unit that was already there, he quickly added that the $600 was for parts and labor. I asked for an itemized bill, which he never provided. Curtis quickly added that he would take down the exhaust pipe from the old unit and seal the roof...and give me a discount because I paid cash. A few days later, I received a letter from Curtis stating that he felt that he was "under scrutiny" and felt that the first plumber (that installed the original tankless heater) had criticized his work. (The first plumber never said a word). I have since attempted to call Curtis to discuss this issue and he refuses to return my calls. I am STILL waiting for him to remove the vent pipe as he stated...and receive a discount for paying cash. I think he knows he has overcharged me and that's why he refused to give me a receipt for an item I paid $1300 for. I also find it hard to believe it took 3 guys, 3 hours to complete this job (unfortunately I was unable to witness the time they supposedly spent there). I am giving him a poor rating due to integrity flaws. read more

I've used CW Plumbing a few times, but after numerous and unsuccessful attempts to have them return to finish a project, I will never do business with them again. I believe they stopped responding because they caused a leak in my walls that went unreported. Now I have thousands of dollars in damage that insurance won't cover. I cannot prove they did the damage, but they were working on the same spot where the damage was later found. There are plenty of plumbers out there. Find another one. read more

I used Curtis Watanabe for two plumbing jobs in the last two weeks. The first was clearing a main sewer line and installing a accessible better drain line entry point. He and his crew did a marvelous Job, locating the problem, going through concrete to get to my drain pipe in the proper location, and finishing off the job with a perfect concrete refill and cover for the new sewer line entry point. I was very pleased when I got the bill - and I don't often say this - because the amount of work that he and his crew did was huge. I was expecting something higher, and was very happy. Then, I had a very urgent broken hot water heater at the house - I called him in a panic and he was here in 30 minutes - fix the problem perfectly and quickly. I had hot water again right away... Curtis is very personable, professional, and I'll be sure to use him and his hard-working crew again whenever I have a problem at the house... Ray read more

Found this company by Nextdoor recommendation Curtis came out and fixed the clogged drain line , great communication and great customer experience, very professional I will definitely use this company again. Highly recommend them for your plumbing issues. read more

Safe customer contact. Showed up on time. An excellent service to our tankless heater. Had a problem for more than a year with water turning cold. After service no issues. Thank you! read more

I would'nt call this plumber, he does not return calls or his line is filled and cannot leave a msg. He sends some of his workers who does'nt seem to know what they are doing, talking to one another about the job, should it be this way or that way, oh! I told you so it was this way etc. Also when ever you finally get a hold of him he has all kinds of excuses as to why he did not return the calls. So if you have an emergency don't call him his response will not be taken care of. Why can't he have a secretary to answer the call, after all he is making money off his customers, what kind of business is this!! So don't call him there are plenty of plumber around that will gladly do the job. I wanted my fauset replaced in less than 30 minutes the job was done, they did not even ask me if it was OK as far as the water pressure, or where my handle should be for me!!! very unprofessional. I will not call him again! read more

I called Curtis to service our Noritz tankless water heater. First of all, Curtis asked questions before coming which shows he's doing due diligence and cutting the time diagnosing the problem. When he came, he was very professional-explained what he found as the problem and also answered our questions. He gave an estimate which is reasonable. He ordered the parts needed for the repair and tried his very best to get them the same day. Understandably, the parts didn't come til next day which is still great in my opinion. His guy came, installed the parts, cleaned up after himself and the best part...the parts ordered were under warranty! On the way out, the service man fixed our front door just because he noticed it needed some tweaking! Overall, just pleasant experience, no surprises, no overcharging! Highly recommend these guys! read more

Over the years I have used no less than 5 different plumbers. Some were okay and some were not due to lack of communication and missed appointments. I had an old Takagi tankless unit go out and I needed a replacement quickly. Instead of trying to get a referral from friends and relatives (which seems to be kind of a crap shoot in terms of quality) I asked our realtor who they use whenever they need work on a house they're selling. They referred us to Curtis and I could not have been more pleased. The price to put in a new Noritz tankless unit was fair, but more importantly Curtis and his crew were timely, courteous and easy to talk to. YMMV, but I won't be using any other plumber. read more

I am writing to commend and recommend Curtis Watanabe and his business. I am the present president of the HOA Board of Directors at 10760 Missouri Avenue is West Los Angeles. After years of woe, Curtis was able to expertly calibrate our tankless Noritz system so that we have absolutely perfect hot water. This after many others had failed. He is a wizard of plumbing. Curtis and his crew are polite, respectful, courteous, punctual, and responsible. I just recommended him to a neighbor. His prices are reasonable indeed. Highly recommended! read more

I had a tankless water heater installed. The plumber who installed it wasn't able to get the remote to work and I was getting just this side of warm water in the shower. Another plumber came over and could not figure it out either. So finally my contractor found Curtis Watanabe who not only installed the remote, set the temperature, figured out why I wasn't getting hot water in the shower and had it all fixed within an hour. He was very pleasant, personable. AND his price was very reasonable!!!! read more

Curtis and his team go the extra mile! They made a rough situation very smooth. When our Noritz tankless failed (after only five years) we called Noritz and confirmed warranty, etc. They recommended Curtis, as did several of my local plumber friends. Curtis was quick to respond and very courteous. When the parts were delivered he came back to install them and realized the gas valve was missing. We got Noritz back on the phone and they apologized, as this would set us back another day or two. But Curtis did not let that happen! He found a way to use parts from another unit as a temporary fix so we would have our hot water running until the burner arrived. That was a difference maker! Curtis knows his stuff and goes the extra mile! read more

Still my go-to for honest and reasonable plumbing work. Vince (Curtis' cousin) came out today and fixed my Noritz blown fuse thanks again!

Curtis Watanabe Plumbing is our plumber to call upon for the last 15 years. He and his crew have provided great service over the years. He recently installed a Noritz tankless water heater when our old one died. Curtis provide quick service and his crew knows our house well. Installation was quick, flawless and neat ! read more

My dad has been requesting for service from this location for the past week. His calls have been screened, no return calls, and the voicemail line is full. We attempted to call each day for the past week to repair the heater exchange on our tankless heater. When we called the manufacturer to call this site, the man immediately answered. Otherwise, we, the customer received no response. If you need to service your tankless water heater, please consider taking your business elsewhere. read more

Recommended by the company of the water heater that we bought. He sent someone the same day to trouble shoot the problem and got it fixed. read more

My water heater started to leak. Curtis came buy in a timely manner. We discussed options and went with a tankless water heater that he recommended. My daughter was bringing 7 friends down from Seattle Pacific University for spring break and we needed the job done quickly. His crew was able to yank the old tank and get the tankless running the next day. They completed the job within a few days. We are extremely happy with the heater and the installation. With tankless we don't run out of hot water and the gas isn't keeping 75 gallons of water hot 24/7. I recommend Curtis and his crew and will use them again. read more

I much prefer having this local plumber than some national chain sending some newbie to fix my plumbing needs. Prices are reasonable and very familiar with homes in the area. Very honest and only suggests what you really need. Curtis is involved with every job and always available. read more

I am on the Board of Directors and former long-time president of the HOA at 10760 Miss. Ave, which is a nine unit condo complex. First off, I have to profusely apologize for the embarrassing review of Curtis' work by another owner in our building. Curtis and his team were responsive and took on a project that the original plumber completely screwed up. At the recommendation of that plumber two years ago, we replaced a blown water tank with a tankless heating system because of the longer warranty. That plumber never set up the system properly, and he had to come back out 8-10 times and we still never had consistently hot water, which eventually regressed to only warm water. He wanted to charge us several thousand dollars more for his ineptitude, which we refused to pay, and he never came back out despite his warranty. For two years, we never had hot water in our building - lukewarm showers at best - and we couldn't find another plumber who would touch the system. It's generally not worth a few thousand dollars for a plumber to take on the liability of another plumber's botched system. I finally contacted Noritz, the manufacturer of the heating units, and they recommended Curtis and several other plumbers. Most of them wouldn't respond to my calls, and one other came out and gave an estimate but without any details in writing. When I finally spoke to Curtis, his team came out and gave a detailed and honest assessment of our system, which had been completely set up wrong by the original plumber, taking numerous photos and drawing diagrams of what needed to be done. He gave a fair quote, and in two days, his team had completely taken apart and re-plumbed the rooftop water heating system for our entire building. It usually takes 30-60 seconds to have scalding hot water now, but I believe a delay like that is not uncommon for similar buildings and is not due to his work but rather the lousy piping layout in an older four-story building. I absolutely would recommend Curtis and his team. They took on a disastrous project that nobody wanted to touch, and fixed an otherwise miserable situation. The other guy in our building who posted an unfair and unfounded review never even asked the HOA or our property management company to follow up with Curtis. He is the type of guy who thinks he knows it all, complains about everything and gets nothing done. read more

I gave 5 stars because Curtis Watanabe not only is very professional, he has resonable rates. I have a tankless water heater that wasn't working. Curtis came over immediately to inspect our water heater and found that we needed things replaced. He called Nortiz and got our parts that were still under warranty and got our water heater working asap. We've been looking for a plumber to use and from now on that will be Curtis. I highly recommend him. read more

I'm so grateful for Curtis Watanabe Plumbing. I've been calling all the heater/plumbers this year and everyone is fully booked and not taking new clients. I'm so grateful because when we called Curtis, he was friendly and helpful. He and his team came on super short notice when our heater broke. The assessed the problem, and immediately gave a quick solution. I felt that his prices were very honest as well. When he was here, he and his team were very thoughtful about my requests as well. I would highly recommend Curtis Watanabe Plumbing for any of your needs. They are awesome! read more

Curtis Watanabe plumbing did a great job on several projects for me. One tough job was redirecting a plugged sewage line. His men were very competent and professional. The fees were very reasonable. I highly recommend them. read more

If it were possible to give more than 5 stars I would. We had an issue with our water heater the Monday before Thanksgiving. We had to turn our water off and replace a part. We gave Curtis a call on Monday evening and he fit us into his schedule the next day so that we would have water before the holiday weekend! Amazing service at a great price! Will absolutely be calling him if we ever have any plumbing issues in the future! read more

Curtis is the best! He was recommended to me by the manufacturer of my tankless hot water heater and turned out to be one of the best individuals I have worked with in 15 years of home ownership. He is prompt, knowledgeable and a great communicator. He is also super reasonable in price which is so very rare in my experience. read more

I previously rated this company 5 stars for service and response. Now trying to get a service response from them is next to impossible. I have spoken to Curtis twice. He would schedule me in and then nothing. I e-mailed, still no response. This is a sure way to kill a company. I contacted Noritz to get another factory trained service tech and let them know the problem with Curtis. I hope he gets his act together. read more

We have used Curtis Watanabe Plumbing many times over the years. He re-piped our house, put a new drain in our kitchen for our remodel last year, and installed the range hood. We had problems with the main drain backing up a couple of times recently. We called Curtis, and he came over within an hour both times! I don't expect him to do that every time, as he has a thriving business. But we definitely appreciated his promptness and courtesy. Not being able to use the sink or toilets is definitely a major inconvenience. We were so glad Curtis came over so quickly. Further, he has an able team of assistants who work hard and diligently, such as Eduardo and Curtis' own son, Jordan. Jordan is a very pleasant, cordial young man who is acquiring his father's vast plumbing knowledge! Curtis is trustworthy, honest and charges fair prices. We ask many questions, and he answers them fully. We trust Curtis for advice, tips and just general information. We have other future plumbing issues, as our house is old. We will be asking Curtis to take care of them. We are grateful to him and his team for their wonderful services. Thank you, Curtis, Jordan and the plumbing team. read more

Curtis Watanabe Plumbing by far exceeded my expectations ! I called on Friday evening because our tankless water heater broke. He called me back within 15 minutes. He was at my house the next morning and stayed all day replacing my water heater. Not only did he replace it, he installed it to code. He gave my husband and I different options to save money. He was very informative with our manufacturers warranty policy. I would highly recommend Curtis Watanabe Plumbing for all Plumbing issues if you're interested in an honest and efficient plumber. read more

We had a Noritz water heater installed as part of new constructionon on our patio in 2007. There was a water heater enclosure on the outside wall of the house. Ever since the installation, we have had problems with it. Numerous error codes, having to reboot several times during the week. It would take about 10 minutes to get hot water to the shower and then about halfway through, the hot water would end and we would get cold again. There was always a chemical smell in the patio area. We've had it drained each year and finally had a taller vent stack installed last month. The problems persisted. I was about ready to yank it out and throw it (if I could). I called Noritz last week and we went through the error codes. They recommended a specific servicing and gave me several contacts for the servicing. After reading the Yelp reviews, we decided to contact Curtis Watanabe Plumbing. Vincent came out late in the day and after contacting Noritz, spent over 2 hours cleaning and adjusting the system. I let him know what our various problems with the unit were and he addressed each one. I feel as if he was a miracle worker. There is absolutely no smell. The hot water is almost immediate and lasts for the duration of the shower. I am thrilled!!!!! read more
