In 1989, John Nakagaki decided to step away from the corporate banking scene, looking for a fresh start. Welcoming this new journey, he initiated a practical apprenticeship, beginning with a drain cleaning machine. Diligently working for different plumbing companies, John rose from apprentice to journeyman, ultimately achieving the role of lead plumber. Over this ten-year journey, he refined his skills, mastering all facets of plumbing, including water lines, drain lines, gas lines, and more.
In 2003, with ten years of crucial experience and expertise, John started his own venture, Nak for Plumbing... After over 13 years of meeting the plumbing needs of the valley, we proudly say Nak for Plumbing is here for you.

Recommended Customer Reviews

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!

One of the best plumbers I have ever had....on time, polite...dressed in a mask! And they did a great job. Reasonable, too. I would say that they are the ones to call for everyone in Pleasant Hill.

Professional, courteous, and text when they are on the way. Very Reasonable price. Will be calling them for all projects.

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.

Very professional and courteous. I smelled gas underneath my cooktop and called Nak For Plumbing to help me fix it. I though it was coming from the gas valve but their testing found it to be the tube. They installed a new one and verified there was no leak before leaving. Would call them again!

Delayed review. Over last year, had two positive experiences. Basic toilet clog. Fast response. Reasonable price. Polite and professional all around. Also, had water main re-routed and other work involving water heater. John is a quality owner and has great staff. Always polite and professional for a fair price. John has talked me out of unnecessary work, when an unscrupulous contractor would have taken advantage. Highly recommend for all plumbing needs.

Our washing machine flooded our garage and I immediately looked up plumbing reviews on yelp. Nak for Plumbing had awesome reviews so I gave them a call. They were polite, prompt, efficient and competent. They fixed the issue in minutes! We are very happy with Nak for Plumbing and we will definitely use them again for any plumbing needs we may have. We highly recommend them!

Contacted Nak For Plumbing through Yelp to change my corroded water shutoff valve to the house. Responded back quickly and answered my question of ""Any rough estimate of how long the job will take?"" with ""worst case would be 1.5 hours to install"". That's all the assurance I needed that this wasn't going to be a really expensive fix. Scheduled the job at my convenience, Jeremy and Anthony showed up on time, went right to work and finished in less than an hour. Very happy with the high quality of work, ease of scheduling, and response of customer service.

Still a great company! Had some work done to the house and pointed out some future plumbing problems that may arise down the road, no high pressure and miss leading advice, just professional suggestions to think about. Thanks John, for doing a great job and being there for us !

I called John at Nak For Plumbing because he was recommended by a friend, whom he plumbed her whole house, and she was happy. There was a gas leak at my house. PG&E came and determined it was not their equipment and said I had the leak on my property. PG&E promptly turned off my gas and padlocked the meter. I called John, and he came right out, gave me an estimate, told me he would need a permit, and he would schedule me right away because I didn't have gas, which I needed for hot water, to use my stove and to heat my home. He worked with me when I had to change the schedule, then came out when he said he would. He re-piped my gas lines above ground, using superior material, and removed the old pipe. He scheduled the inspector to come and everything was signed off. John worked hard, and everything was professionally done. I am very happy with using his service. PG&E, on the other hand, is terrible. They were quick to turn off my gas, but are taking their sweet time to turn it back on and relight the pilots. Thumbs up for John. Great job at a fair and reasonable price.
