Founded in 2015 by Shane Mizusawa, our company is known for meticulous handiwork as well as our exceptional customer service. We are not a giant chain looking to make money off of you. We are your neighbors, ready to help you anyway we can.
At 535 Plumbing, we like to think of ourselves as your neighbors and friends, not your contractor. We genuinely want to work with you to solve any issue you may have, treating you like family instead of work. We know that plumbing of any kind can be overwhelming. That's why we offer plumbing services of all kinds.
There are a lot of reasons you may want to remodel or renovate your kitchen or bathroom. Whether it is an unsightly remnant of your home's previous owner, or you want to spruce up a property for potential renters, there will almost definitely be a time when you will have to seriously start thinking about a makeover.
Getting new appliances and fixtures for your home can be exciting. However, they can be a challenge to install, especially if you've never done it before. Plumbing-related appliances and fixtures require installation to be done properly, not just for functionality's sake but also for safety. Improper plumbing installation can cause issues such as water leakage and damage, appliance breakdown, and more.
Buying a new home, while exciting, is not without stress. One thing that all homeowners should do before purchasing a new home is hiring inspectors to thoroughly search the property for any warning signs and red flags. These could lead to major issues for you down the road.

Mom's plumbing was old and deteriorating. 535 Plumbing came in and did a super job installing a new water heater and repiping her home. She is extremely happy with the increased water pressure, super hot water, and clean and clear water.

535 Plumbing inspected the property, provided options to fix the problems, and provided a reasonable estimate. After comparing them with other plumbing companies, we selected 535 Plumbing and we're extremely satisfied with their service. They completed the work as promised, in a timely manner, and stuck to the estimate provided even though there

Called 535 for a leaky toilet and a dripping shower faucet. Scheduled at 9am. Puni, the service technician came in at 9am. ON TIME! Awesome!

Not only did Puni do a great job fixing the problems but he is just a nice and pleasant guy. Top notch customer service, punctual, hardworking technicIan and fair pricing. I really cannot ask for more.

I will definitely do business with them next time I have plumbing issues. Shane M. You should be proud to have such a great group of people working for you.

Please read full review.

Overwhelming, that's how I can best describe my experience with 2 other plumbing companies we've spoken to. We own an old home with a lot of issues, one of them being the plumbing. The first company we spoke to understood what we wanted done, but didn't really take in to consideration what we could afford. Another company sent a representative that wanted to pile on a bunch of stuff on top of what we were already asking. That rep literally walked around our house saying "we can do that" to every little thing he saw. I was beginning to think he

It took me awhile to do this review of the water line installation for my newly purchased refrigerator. Called them after seeing their TV commercial one evening

They didn't do a site inspection but ask me to send pictures instead for the scope of the work needed. Original plan was to run the line from the sink water line to the opposite wall, through the cabinets and behind the range. Owner said going behind the range was usual but I had my doubts because it is a drop in range and not a slide in. Fortunately when the two plumbers came the next day, We came up with an alternative that worked

The measure of a business is how they react when something goes wrong. And if it does with 535 Plumbing do NOT expect courtesy, professionalism, or least of all, satisfaction. So if you use them, pray everything goes right or they will fall back on quoting their policies and tell you why they can't fix the issue. I experienced this firsthand. Be smart and choose another plumber, one who behaves professionally.

I had an emergency plumbing situation in a condominium building where my plumbing was leaking into the unit below. 535 Plumbing responded with over the top service. The reception staff determined the urgency of the situation and responded exceedingly to my needs. Thank you Laura and Pam for your expedience and service follow-up.
Special thanks to plumber Steve and Chrystyan for their sincere and professional service toward me. Dry wall staff Joel and Butchie did excellent finish work on the affected walls. I am sure there were others that also contributed to this seamless operation on my properties

535 Plumbing assisted us to unclog a disaster at our family home in Kailua. They used a camera system to investigate the issue from the toilet line all the way to the street. Dalen was very thorough and explained the issue from start to finish. We were able to resolve a major issue early one which saved us thousands. Thank god for 535 Plumbing!

This is the third time we had 535 Plumbing complete work for us. This review is long overdue.

It is easy to get an estimate. Submit pictures on line and they will send you an estimate. Once you agree with the estimate, they will email or call you to schedule the appointment.

Pricing is fair.

They were able to come out the next day after I made my inquiry this time. In the past, they were able to come out on the same day. Depends on what kind of work needs to be completed.

They will call you when they are near to let you know they are on their way. They do excellent work. Clean up all rubbish

Had to change out a rusted toilet ring and take out an existing sink and replace with a new fixture. They were responsive to request (they ask for pics so they can provide a quote via electronic communication). I was able to schedule an appointment the following day and the work was completed. Highly recommend.

I'm a renter and had been waiting for my agent's usual plumber to call me back for weeks regarding a clogged tub drain. I was tired of waiting so I called 535 and they came the next day. They sent 2 techs who unclogged it quickly. No fuss. I paid them cash and now enjoying a free-flowing drain.

535 did an amazing job installing a double vanity including faucets, drains, piping, valves and drainage lines. Butch and Joel were professional, knowledgeable and completed the work in timely manner and to budget! If you want the job done properly look no further. Big Mahaloz for a stellar first experience. I highly recommend!

If you value your time, call 535 Plumbing. They answer the phone, schedule you and meet their time commitment. Professional and down to earth. I've needed their services for two occasions and couldn't be more satisfied.

Thank you 535 Plumbing! Keep up the good work!

We had to find a plumber urgently because our waste water sump pump alarm was screaming at us.
My wife searched on Yelp and found that 535 Plumbing had good reviews. She called and within 2 hours we had two very polite and professional plumbers at our door, Dalen & Ali.
What happened over the next 4 hrs was not particularly pleasant. Dalen was hanging upside down for much of that time with his head well down the manhole. He had to vacuum out, then dismantle everything so he could lift out the pump. When he cleaned and freed the impeller he then had to reassemble everything again hanging

My day started off badly with my mom breaking the hose bib off the pipe. It had been rusted through and was gushing water all over the front yard. After turning off the main water valve, I turned to yelp to find a plumber that could come out to fix it today.

I ended up calling 535 Plumbing based on their great reviews and having contacted them earlier for another job, but didn't end up using them the first time.

This time I went ahead and had them come out. I spoke to Laura and she was very helpful. She scheduled a time for someone to come out at noon to 2 pm. They ended up getting

Excellent service. Both over the phone and on day of repair. Needed minor replacements and repair on two of our toilets...on Easter Sunday no less!!! They were quick, friendly, and professional from appointment scheduling to installation and answering of my many questions. $572.19 with a military discount. They also offer senior citizen discount. That was for 2 toilet flush assembly replacements and a new angle valve. A little pricey, but I didn't have to do it, so it's worth the price to me.

You have to say " Don't Dispatch Keone " when you make appointment.
He was so rude.
not a professional.
He had done such a sloppy job that I had to look for anther plumber.
Billing is more than twice as high as others.

Mixed review as I feel the experience could have been better...As a recent first time homeowner, it was my first time having to deal with my bathroom sink leaking. The tail pipe was leaking every time I used the sink until finally I noticed a puddle forming in the cabinet. It got worse over the Christmas weekend. I went onto Yelp and noticed that 535 Plumbing had excellent reviews, so I took a chance and called them on a Sunday and was surprised and grateful that they answered and could send a technician to fix it. The friendly dispatcher was very professional and kind, and quoted me $225. I was

I called these guys on a Saturday morning and they were at my place by 10am. Polite and professional, they were using masks and were good communicators, showed me exactly what needed to be done and got me a quote and fixed the problem on the spot. Everything was fixed by lunchtime and i was completely assured that it was done right. i'll call them again.
