NAK is great and professional. Easy scheduling and good service. Price is a little high but it's worth the peace of mind.

Contacted Nak after trying another plumbing company to fix my inlet water pipe crack to my house that was flooding. I had no water and they prioritized my call and fixed the problem. They were efficient, responsive and professional. Would recommend them for any plumbing needs. John, Zack and Arron were the crew to help diagnose the problem, get a solution to address the problem. And fix it timely. Couldn't be happier. Thanks gang! read more

I used Nak because of the number of high ratings, figuring that if you can get consistently high ratings as a plumber, you're probably doing more than one thing right. I was expecting prompt, effective service, but they really did deliver on more than just those fronts. They scheduled my appointment quickly, had plenty of very clear communication and confirmation, the technician (Zach) called and offered to arrive early rather than just doing it and potentially catching me off guard, and he exemplified the kind of service I would want to see if the company was mine. Very friendly, very patient, and very upfront and transparent about pricing. I would not only use them again, I don't even see a reason to ever use anyone else. read more

Today was the first time I've tried the service of "Nak for Plumbing" to fix some plumbing-related issues with my home, namely swapping out a new same-model garbage disposal that I bought separately to replace the old one that quite working & since they were here for that, finally using that as an opportunity to have them fix a broken sewer cleanout overflow pop-out that wasn't worth the truck roll until I needed a plumber for something else anyway. I submitted a request for a quote via a form on their website, and promptly received an email reply from Keiko (thank you Keiko!) with an estimate. I called around to get a read on other pricing and they were all in the same range, so based on Nak's review reputation, their closeness to my home, and the fact they are a small mom-and pop business and not some plumbing chain/franchise, and another employee who answered the phone, John (thank you John!), was super nice and helpful when I called, I went with them... and happy I did! Miguel from Nak showed up at the beginning of the hour window, was really nice to work with, was tidy and thorough, and took care of both tasks within about an hour. He was straightforward with me, stuck to the exact quoted pricing (because no other problems were found), allowed me to pay by credit card with no added fee, and also took the old garbage disposal and any related collateral with him, which I was really happy about. I absolutely intend to contact Nak for any future plumbing needs, and also will happily recommend them based on my own positive experience, but also because it's obvious they are good guys from both the overall reviews on Yelp as well as Google reviews. It feels good to support a small, worthy, local business! Thank you again Miguel and team Nak! read more

Had a bad cartridge in my shower. They came and replaced it the same day. Very polite and professional. A+ service. Thank you.

I think what impressed me most is how much time the owner John spent with me on the phone. I described my issue - a leak inside the first floor ceiling from an unknown source, probably a second floor fixture. There was a wet spot and a small hole from a different plumber who proved relatively unhelpful. John spent considerable time asking questions, suggesting possibilities, etc. He made it very clear that he hoped to avoid showing up and cutting holes in ceiling board, as water can travel. Note that the other plumber had no tools, said cameras rarely reveal leaks, and made poor suggestions... like caulking around a tub rim that hadn't been used as a shower or filled more than a few inches. John and I agreed in a plan to help identify the likely source. Twelve hours later, that proved mistaken, the "diagnosis" changed due to new information and a visit was scheduled. Their plumber and assistant arrived. My ceiling was checked in multiple areas very thoroughly with a moisture detector. The plumber spent considerable time trying to determine the pipe routes. I agreed to let them start cutting holes - they started by slightly enlarging the existing hole from the previous plumber. Inserted the camera, and located the leak in 2-3 minutes. They opened the ceiling and repaired the pinhole drip. The entire visit was under 90 minutes. The cost was much less than expected. No exaggeration- I looked at my phone - John spent almost another 90 minutes trying to help me on the phone at no charge - who else does that?! I'm convinced that, had I continued with the first plumber, I'd have holes in my ceiling board in several locations, and a much bigger bill. I'd used Nak previously - this reinforced my loyalty as a customer. read more

Installed our earthquake emergency shutoff valve within 30 minutes. They were fast and efficient and very friendly. Will look to them for any further plumbing needs. read more

Great place for plumbing service . Been using Nak for years. Always on time reliable and neat.

I've had Nak for Plumbing out for a few things and am always appreciative in knowing that when they're gone, the problem is good and solved! Recently had Sandeep out to repair a weak spot in my 4" cast iron waste stack. He looked at the pipe and discussed the options in repairing it. I chose to replace it with same (cast iron) since it much quieter than ABS. The repair looks great, the work area clean and you'd never know he was there. I then needed them to come out to do my gas earthquake valve. Once again, Sandeep did a great job. I asked to adjust how my meter was rotated (rotating it in a bit towards the house) and Sandeep handled it like a pro, no problem. Thank you! I will definitely be calling Nak for Plumbing again. They take care of the problem! read more

I needed to replace a thermocouple on a water heater. Nak for Plumbing responded quickly and scheduled repairs the next day. Second time I've used their services and was very pleased. Fair pricing and was not "Oversold" as another plumbing company tried to do. Nak for Plumbing is now my "Go To" for plumbing needs. read more

Nak for Plumbing is outstanding. They are easy to work, show up and complete work on time, and the quality is excellent. They are most excellent. read more

Needed a new water heater, called Nak. Keiko asked a few questions, quoted a price for the job, and set up an appointment over the phone. Brandon, Mikael and Chia replaced the water heater and did a meticulous, efficient, and professional job. They also noticed that the pressure regulator was no longer working, so they quoted a price to replace that. Chia did the work the next day and did another great job. It looked so good I took a picture. I have been using this company for 15 years and am still impressed by the quality of their work and the ease of working with them. Thanks again team Nak. read more

Highly recommend Nak for Plumbing! I had started a bathroom remodel but also had a list of other plumbing issues that needed attention. The jobs included conversion from two to one sink plumbing, replacing a pressure reducing valve, replacing a galvanized pipe, and replacing a tub spout that was rusted in place. Niles and his crew were very responsive, explained and answered all my questions. I have no doubt they will be the first ones I call for any future plumbing issues. read more

Nak for Plumbing is the best!! I've been using this company ever since we moved into our home almost two years ago. Whenever I have any questions or issues, John is so helpful. He either can advise me on what needs to be done or has a technician out to my home asap. Nak for Plumbing is ALWAYS fair and honest when it comes to just doing the work that needs to be done. A special thank you to Chia Chun who came out to clear a clogged sewer line and look over some questionable water valves. He was very knowledgeable and explained everything which I enjoy as I'm learning a lot about my home;) read more

Needed some help with a failed do-it-yourself job and Nak Plumbing was able to send someone over within an hour. They saw that the job was fairly straightforward and quoted me a price that was higher than I expected, but given the quick response I went ahead with it. The job was completed efficiently and it's been a couple of weeks and no leaks or other issues, so I am pleased with the results. I'm a believer in the idea that you can get something done with high quality, low price, and quickly ... but you can only have two of the three. With Nak Plumbing I think you get the quality and the speed, but they won't be the cheapest. read more

I highly recommend this service. They were on time and professional. Offered great advice to address some of our plumbing concerns.

Very happy I chose this company! I kept getting the run around with other companies, passed off from dispatcher to dispatcher, or they just wouldn't respond at all. Nak for plumbing was responsive, communicative, and efficient. The workers that came to set up my drain were very friendly, arrived on time and worked quickly. I would definitely use this company again and recommend them to anyone! read more

They were nice folks, but still couldn't fix the problem. I had a stopped up yard drain. NAK was very responsive. They sent somebody out the next day. Their guy worked on the problem for 2 hrs, but couldn't solve the issue. The only piece of equipment they had was a small battery powered snake. I would think that they would have a camera to check the line. Or, even a larger snake. Again, nice folks. But, they couldn't fix my problem. read more

Be good to him, he's the real deal with 40+ years of experience. read more

Rock stars! We had a simple toilet fill valve replaced and a couple of other remodeling questions. The woman that set the appoint was quite nice. We got text and email confirmations of when the appointment was and who was going to be sent to our home. Jeremy was great! Not only did he explain the process nicely his Customer Service is exceptional. Seriously, he could change into a tux and be a fantastic Maitre'D at a 5 star restaurant. The issue was fixed, for a fair price and and we will always go back to Nak for Plumbing for our Plumbing needs. read more

Thank you and Eugene read more

Replaced my kitchen faucet and water supply valves. They showed up on-time, worked efficiently, and left the job area neat and clean. Two workers made the job go faster. They happily explained the job and instructed me on how the new faucet worked. When completed, the price I was given on the phone was the price I paid. Very happy. read more

Anthony and Jeremy are FANTASTIC! Anthony took the lead and did an amazing job. He was early and courteous, provided proactive updates, problem solved, and cleaned up beautifully. Pricing is also very competitive. I definitely will hire Nak for Plumbing again and recommend them to others. Anthony is stellar at engaging customers on top of doing the work. read more

I will recommend Nak plumbing to all my friends. Mikale came out and was very professional. Had a stubborn problem with a shower valve that would not come out. Problem solved and everything up and running. This from a former HVAC technician who is now having health issues and used to fixing everything myself. I think I found my go to plumbing company. read more

I had a great experience! I received a quote and it didn't change after the job was completed. The installation was seamless. Jeremy was quick, efficient and friendly. I'm very happy with the service and will use them again. I will also recommend Nak to others. Thanks again, Kelly read more

When expressing a concern about charges for service Mr Nak's response was "I don't care".

Arrived on time and prepared. Mikael was friendly, efficient and tidy. He was completely COVID ready with mask, gloves and shoe coverings. I've been around for a while and no experience in home repairs was better! Thank you. read more

They were quick to respond and helpful with getting things done on time. I appreciated their professionalism throughout. Jeremy, the tech, also wore a mask and distanced through the appointment so thumbs up for COVID safety. I hope I don't need plumbing help again any time soon, but I'll definitely call Nak! read more

Contacted Nak on Tuesday morning due to a leak I was having in my kitchen. A plumber (Don) was sent out an hour later, got straight to work and detected the issue that a pipe was clogged from the unit above my condo. He was very thorough and explained everything he was doing. Within a couple of hours, the problem was fixed and I no longer have water gushing down behind my walls. Thank you, Donald, for coming to my rescue! read more

Nak came out and replaced my broken water heater during that same day. Their tech was not only on time and courteous, extremely professional and respectful of my time. Their pricing was fair, especially for same day service. I got my water heater replaced promptly, they even replaced my lines and valve switches. read more

My family has hired Nak for Plumbing twice to work on our business in a commercial unit. Their team is friendly and reliable; great work!

I highly recommend this company for quick, reliable and fair priced service. I had a major clog in my toilet causing my shower to back up with sewage. I reached out to Nak Plumbing through Yelp and heard back within minutes. They quickly provided both an estimate and same day availabilty. After reading through their 5 star reviews, I chose them over many other companies in the area. They called me within an hour to offer up an earlier appointment that I was happy to take. Two plumbers arrived promptly, my main point of contact was Mikael. They were both very professional, COVID safe and friendly. After showing Mikael the issues he openly communicated the pricing I should expect to snake my master toilet and remove the toilet as well. The job took 3.5 hours. The clog was quite bad and they had to bring in a much stronger snaking machine. After they fixed the clog, they took the time to vacuum the backup in my shower and cleaned up after themselves. Even though the job took much longer than expected and many attempts, they stayed true to their word with the cost estimate provided. Going into this experience I was very stressed about the potential cost especially after hours passed. They managed to make this experience a smooth one and they will have a long term customer and referrer from me. If you need a plumber, read the reviews carefully. Nak stayed true to theirs! read more

II hesitate to tell everyone how great our two experiences have been because it will make it harder to book them when we need them... but we also want them to be rewarded for being awesome. Friendly, fast, fair, responsive. Everything you look for. Both of our projects were far trickier than they should have been because of bad previous work by others. And both times, Nak sent people who solved the challenges creatively... and still quickly. Couldn't be happier. read more

I'm rounding from 4.5 stars. Nak is a serious business that wants you to be satisfied with the quality of their work. In our case they fixed a drain leak, but left without the stopper working. They made a priority of coming back to fix without any pushback. I like them (2nd time customer) and will call first next time I need plumbing work done. They do come in a little pricey, but come through on quality. read more

John came and was able to diagnose and fix the leak. We hired him because he explained everything and was very honest with us. He also checked our other pipes under the house and told us where an animal had been burrowing into our crawlspace. We will definitely be calling John again for any future plumbing needs! read more

This is a small family owned business John and his wife run it . I will use them for any future plumbing needs . He is licensed and insured He came out today to have a look at my corroded gas line and didn't recommend any unnecessary repairs read more

I was referred to Nak for Plumbing by a friend and couldn't be more pleased! From the super friendly people who answer the phones to the 10 star plumber that came out. Eugene was AMAZING, I had pulled out my kitchen faucet and plumbing to replace it all and got stuck on one slip nut on the pipe going in to the wall that had corroded and cracked and I couldn't get it off without fear of damaging the pipe going in to the wall. He had seen all the work I had done trying to do it all myself so he coached me through the whole process of getting it off and waited to make sure I got it back together leak free and didn't charge me anything for the advice. I can not imagine a more kind, knowledgeable or helpful person. I will for sure be using Nak for Plumbing for all future plumbing needs! read more

Professional, courteous, excellent work. Will call if or when I require plumbing services. Highly recommend them.
