Best Tankless Water Heater Installation in Honolulu HI

There's a reason that Little Big Plumbing (LBP) has so many positive Yelp reviews.
From beginning to end, my experience with LBP was a very positive one.
Brendalyn was very diligent in contacting me to schedule a visit. I was told Mike would arrive between 2and 4pm, and at 1:45pm, I got a call from Mike saying he was on his way.
When Mike arrived, his demeanor and professionalism were exceptional. He was very knowledgeable about the particular issue I had called about and even referred me to local parts places to save money in the future.

Our shower leak was repaired, and the whole process (even the payment) were pain-free! I would highly recommend LBP to anyone who has plumbing needs.

Punctual: Yes
Quality Work: Yes
Professionalism: Yes
Fair pricing: Yes

Thanks LBP - I hope I don't have to call you anytime soon :)!
But if I do, I know we'll be in good hands.

I talked to Neil at Shaka Plumbing to come fix my faucet that had a major leak.   Scheduling service was a breeze and when he showed up he instantly  knew what the problem was and had the parts on hand to change out the defective pieces.  His pricing was also very reasonable.  Neil was in and out and he seems to be an honest plumber that I would trust for future jobs.

Will highly recommend to anyone who has trouble or any problems with the plumbing in the bathroom or kitchen. They all will be solved with the good job!
The owner with his son were so amazing.! With my deeply appreciation.

We have had some crazy plumbing emergencies in the past few months...exploding water heater, low pressure in the kitchen faucet, leaky toilets. Whitley returned our calls and also answered messages right away and was so great and knowledgeable with everything. He stayed till the end and made sure the job was done right EVERY TIME he had to come by. He even was able to adjust our water pressure gauge (or something like that) that was coming into the house from the city. He's my go-to plumber from now on and should be yours too!!!!

This is our first experience using this company for our business and I am glad we did. After reading some reviews, I decided to use them since we already tried Roto Rooter and while they did the job, were very expensive. These guys were very reasonable priced and did a great job. I will definitely contact them again if we need service. They have good customer service and Shane will text you in a timely manner. The reviews from the others are  accurate.

We wanted to get an exterior pipe shortened, a quick 15-20 minute job.  The guys were prompt, efficient and left the job site perfectly clean.  On the way out, the lead plumber noticed that another exterior hose fitting was basically welded shut from corrosion since we live just off Kaneohe Bay.  He offered to fix that as well on the spot with an upgraded spigot.  I was pleased with the value for money and their prompt service.  Definitely recommend Full Service Plumbing.  Their company title doesn't lie!

Chris continues to offer above and beyond service and will squeeze an appointment in when he can. I texted Chris about a Costco refrigerator installation that went wrong. He called back immediately and stopped by at the end of his day to help us out! He has done bathroom and kitchen work for us and he's the best!

Hawaii drain Pros came back and fixed the valve they broke free of charge. They did a good job it no longer leaks. Thank you!!!

Had a sink/faucet install and it couldn't have gone better. Looks great. Friendly service. Clean efficient work!

I needed a valve replace, but the new valve was 1/4 too wide.  Called EPS and spoke with a friendly dispatcher.  A professional, friendly technician was sent out and I explained the problem.  I was quoted $540 for a job he estimated to take 1.5 hours to 2 hours.  I figured that comes out to roughly $300/hour, which is high, but for my convenience, I was willing to pay.  (I supplied the new valve, so no new parts were needed.)  Technician took 20 minutes beginning to end to replace the valve.  

$540 for a 20 minute job?!?!?!?!  

I don't really write reviews, but thought this price gouging deserved my time.  Pricing like this doesn't seem right and unethical.  As much as I value customer service (the technician and dispatcher were professional and pleasant) the pricing is too significant to overcome and therefore one star rating.

They responded to me immediately, were at my house within 45 minutes, and took care of the problem right away. From the time I contacted them to the time they finished was at most 2 1/2 hours. The workers are also very easy to work with and talk to, which I love. I'll definitely be calling them again should another issue come up.

I was not happy with dimond head plumbing's customer service at all. We discussed repairing the hole with either drywall or a flush mounted access hatch panel (which would be less expensive). I was somewhat concerned about the appearance of the access hatch, but after they sent me a photo of the product and I looked it up online, it seemed like it would look tidy with finished edges and not draw the eye as it was flush mounted. Then they came, did not have the product they had shown me in the correct size (though I had given them the dimensions of the hole ahead of time) so they went ahead and installed a different product that is essentially just a piece of plastic that is not flush with the ceiling with raw drywall edges underneath. I expressed my concerns about its appearance and they blew it off, said they had just shown me an example product and they had installed something equivalent. I told them it may be functionally equivalent (both are access hatches) but aesthetically it certainly isn't. They offered no resolution to this issue--except that they offered to charge me again to come install the product they had initially proposed (no thanks). To top it all off, they quoted $250-400 and charged $550 + tax.  I would recommend using a different company.

This is among the WORST PLUMBING company is KAMAAINA PLUMBING AND HOME RENOVATIONS. Other than that they make very good alibis to justify their high fees as if they did it themselves really good thought it's just simple task.
Called their office for emergency clogged up toilet and the office personnel is so rude and saying they could not attend as soon as possible since plumbers are already all out and promised to call me back in 5 minutes... never called back!!!
I called other good reputation plumbing company among the best and ask help and came right in time as requested.
DO NOT USE KAMAAINA PLUMBING for any plumbing works.
I don't think recommend this company.

Darren and his team were PHENOMENAL!  We hired Allen's Plumbing to reroute our home's old sewer lines (1950s). They were on time, extremely professional, and got the job done as promised! I would recommend them for your most challenging plumbing issues!  Knowledgeable, friendly, reliable, what more can I say?!  THANK YOU!

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.
