Best Tankless Water Heater Repair in Honolulu HI

Mahalo Chris for your professionalism and quick service to fix our leaking hot water stem valve shut off under the kitchen sink.  You go above and beyond to make sure that you do the job right and your work is real clean.  We will call Little Big Plumbing for our future needs!

The only reason I would give more than a one star rating is because they act professional and show up on time.
However, they advertise 24/7 service but did not answer on a Sunday when my water pipe broke.

I did a self repair but wanted a plumber to redo my work for insurance purposes. They quoted me 460$ to replace three feet of pipe and to raise a shower head ten inches.

The tech said it was so expensive because they do not replace cpvc and the copper is expensive. Well, an eight foot section is only 14.97 and all the materials to cut, couple, and sweat the shower pipe don't even come to 50 dollars. I asked the tech to call his boss to try and get a reasonable price,  he wouldn't do it in front of me, instead he walked outside and came back saying his boss actually said it should be 480$, which made me lose trust in the character of the business I was hoping to work with.

I was looking forward to feeling confident in Shakas work based on their great reviews and thought I would feel confident  my house wasn't going to flood, instead I feel like I was a profit target because I am a young homeowner in a mildly desperate situation.
I will never conduct a transaction with this business.

Jaren just left, what an excellent  plummer! Wish I could give him ten stars! After 5 minutes he solved the problem. Strengthening the down pipes, I don't  have a pool in my kitchen anymore. Jaren is a superstar. Highly recommended. Mahalo  piha.

Believe the 5-star ratings!  First Class Plumbing. The name is so appropriate. Whit was first class all the way.  Courteous, caring and extremely Professional. Treated me like his friend or ohana. Had water heater problems and he responded immediately. He even took an extra trip to the store to assure I got a product that was in the best possible condition.  That's taking pride in his work. I was unlucky with the plumbing problem, but was fortunate enough to find this company and especially, Whit.

535 worked extra time to move our hot water heater! Friendly and responsive and extremely patient with us when we changed our minds about the direction we wanted the job to take.
Highly recommend their team!

I highly recommend Full Service Plumbing.  Unlike many of the franchise companies, an actual licensed plumber, Owner Jeff Gilbert, came out and gave me a sound evaluation of my 54-year old cast iron drain pipe, and a fair price for replacing 35-feet of 4-inch pipe, one cleanout with a new 2-wye cleanout and a new connection/cleanout to the street lateral.  They did the work ahead of schedule and added some extra work that they did not charge for.  His young men were courteous and hard-working.  I will call them for any future plumbing work that I might need and recommend them to my family and friends.

had him assigned to us from a home applince insurance policy. changed out the cartridge for our bath tub and fixed a leaky sink. good response time

They're Pretty efficient, customer service is great, always return your calls. if you live in an apartment, best thing to do is organize a water shutdown first to avoid delays. Also, get an imprint of where the walls connect. It's a tricky thing to fix pipes in an apartment building. It's easier if you have a house cuz you can shut off the water whenever you want. But you have to work around the plumbers availability as well, which was what Happened with us. Expensive, but the guy worked pretty hard. He had to cut through the back wall that was connected to the trash chute of the building. It took About 5hrs to patch up a leaky shower faucet, to install new fixtures replacing the old rusty ones Such as the tub spout and faucet and copper wire pipes.

Excellent Service & Very accommodating to every question & need. Zeke was our Specialist
did a fabulous job!

We were having problems with our water valve. Called this company up and they came to repair right away. Kyle did a good job fixing it up! Awesome job guys!! I highly recommend them!

Jack was great about responding to my issue with my water valves connecting to my washer. He made a house call to check out the situation and give me a quote. The fix was going to require a water shut down in the stack of my building so we scheduled for a different date. Jack finished the job faster than expected and he was nice enough to fix another minor issue with my toilet running that a previous hired handyman had messed up and ghosted me on returning to fix the issue himself. Jack was extremely professional and got the job done for a really good price. I recommend him for anyone who needs a plumber and will definitely use him for future jobs if needed.

Called them on President's Day holiday and was surprised that they were open. John came out to my house within an hour to fix my shower faucet handle that was stripped. He was pleasant, courteous and professional. Thoroughly explained the problem then proceeded to get the job done. I feel that his fee was fair and the best part is that he didn't charge me extra due to the holiday. Diamond Head Plumbing will be my first choice to fix my plumbing problems from now on.

I called at about 9:00 in the morning because there was a leak under the kitchen sink.  The woman (she was rude, just like the other commenters said) took my name and number and said she would call me back.  I called back at 4:30, and the girl who answered the phone, said the woman I had talked to, had gone for the day.  She would leave a note.  Well, fast forward the next day.  I hadn't heard from them by 9:00 so I called my regular plumber (Kamaaina was the subcontractor on a home renovation).  They didn't know when they could send someone out, but within a couple of hours, a plumber showed up on my doorsteps, bushy eyed and eager to work.  It took about 3 hours to change a hose, but that was because he had to search the island to look for the right hose.  Can't fault him for that.  Better to make sure you get the right part instead of going back and forth.

I had a major issue with my sewer back up on 5/2/15. BENNETT came out to help with the clog. AWESOME service. I am not knowledgeable with maintenance around the house. I am truly grateful for his patience with my questions. Although he couldn't fix the clog on his own because the issue was so major that a simple snake couldn't do it, he went above and beyond to make a call for me to someone who can assist. Not only did he make the call for help, he kept trying to snake the sewer line and even  put a camera to diagnose it to try uncover the real issue.

SCOTT, and the Jetter had to get called in! Scott came with his machine and not only did he unclog the pipe, the main sewer line, but investigated to find the root of the problem. He and Bennett discovered a crack in the sewer line. Scott even took the time to show me the camera footage in the sewer pipe and explained my situation.
I really appreciate their patience, knowledge and the fact that they stayed late to help me even though they missed the Pacman and Mayweather fight! Thank you BENNETT and SCOTT from Allen's Plumbing for your help!
Scott even called Daniel (sales guy) that same visit to have Daniel follow up with me Monday to get quotes.

Yes, Daniel called me on Monday to tell me he will do the estimates for the fix today 5/5/15.

Awesome service by Bennett, Scott and Daniel. Thank you Allen's Plumbing!!!!!!

Got a decent quote from Jay.  Said he could be out between 7:30-8:00pm.  Great!  Asked for pics of my pipes, which I sent, then never heard from him again.  No, I can't make it tonight.  No Can I reschedule?  Just silence.  I even tried calling and he wouldn't answer the phone.  I could've spent that time finding a more reliable plumber.
