Recommended Customer Reviews

CHAD is the man. I have used this company and have had the pleasure of dealing with Chad each time. What a great guy and a superb plumber. TOday, because of my own stupidity, Chad had to come twice....the second time to clean out the main drain. It was already close to the end of his work day, but he came and worked two hours to clear the line. HE didn't scold me, but said toilet paper was the only thing that should be flushed down, not wipes, not paper towels, no sanitary napkins, etc, Always ask for Chad...a great guy.

Another smooth annual backflow testing! Cost is half of what I paid at Waialae Plumbing from previous year. Thanks again and see you next year!

I called TNH plumbing and Russell showed on exact on time. He's the coolest guy ever, easy to talk to and very knowledgeable, and honest. I highly recommend TNH plumbing because of Russell's excellent service and representation.

Found this awesome business thanks to Yelp. Chad came out to fix a leak in our bath tub. Couldn't be happier with the work he did. Very fast worker and took the time to explain everything. Will definitely be using them again in the future.

I have used this company twice in the last two years, the second time got to deal with Xena over the phone she is very nice and helpful and follows up with you, she is very proffesional and yet seems like an old friend. I have been very fortunate to have plumber Russell Oyama both times, he is a decent and super nice person. Russell is a very skilled, honest, plumber. He does not dilly dally he finishes faster than other plumbers. And he is very honest with his suggestions. I feel that Russell is a great asset to TNH, I will recommend Russell and TNH to everyone that needs plumbing service. As a home owner for many years and landlord I have had my fair share of plumbers, and I can tell you not all are honest and they will get you on the time and try to sell you things you dont need. I also purchased my badger five disposal from TNH, because theirs was cheaper than lowes and home depot I called, and T N H had a better price. As long as Russell is there I will continue to use TNH plumbing and refer them to people who need good decent plumbers. Thank you Russell for the beautiful job done on my new sink I know it wasnt easy to replace the almost twenty year old sink, and to use the same counter, but you did a fantastic super beautiful job. Thank you, for money well spent. Oh also two years ago he replaced my toilet and I think he did it in less than an hour and that toilet was almost eighteen years old.

Five Star Service from Chad at TNH Plumbing! We called them for a toilet repair job & they sent Chad who was very knowledgeable, efficient, and easy to talk to. After he fixed the toilet, we asked him if he had additional time to take a look at a shower valve that was malfunctioning; as we had the replacement part; but not the expertise to fix it. He replaced the shower valve with no problem and it only took an extra 20 to 30 minutes or so to do it. We were very appreciative of his service. We would definitely recommend him and TNH for future plumbing repair jobs.

Business doesn't return calls, left 3 messages to have them call me back. Unacceptable.. glad it wasn't an emergency! They used to be good , now they don't return calls and there business hours apparently fluctuate....

As an Elite Yelp reviewer, i always trust my yelp referrals. TNH was the best and we since have referred them to our neighbors and friends. Chad worked on our home plumbing when we remodeled our guest bath. He is highly experienced and explains clearly what he is doing. Prices are reasonable. TNH runs an efficient office. Christy manages the office and is very efficient and friendly. Chad checked our water pressure and found it was way too high and quickly readjusted the pressure as we could of have had blown pipes. With Chad he not only performs great plumbing service he also educates us on our plumbing and water heater. Look no further, call TNH!

I didn't need a plumber until now. Noticed a leak on the bottom of my toilet and finally called. Since we use them where I work, I figured why not. From the time I called to get a price on how much to the time they came out, I was impressed. They assigned Chad to come out and do the work. He was very friendly the whole time. I also had an issue with my cleanout plug and he recommended I get a plug for it instead (which can be found at Home Depot, Lowe's, etc). He warned me that it would be a really big job. When he took out my toilet, there was a leak indeed. He put in a new flange and new seal and recaulked the bottom of my toilet. I will keep them in mind for future jobs. Thank you.

After returning home from a trip, we discovered our washing machine shut off valve had been leaking for quite a while. The water started to spray out so we decided to look around for a plumber. After calling TNH Plumbing, they responded promptly and sent a plumber out to evaluate the problem. Chad was able to purchase the needed materials and complete the job today even though he was booked solid. We really appreciated his professionalism, knowledge, and kindness in fitting us into his busy schedule. For all our future plumbing needs, you can be sure that we will call TNH Plumbing. For fast, dependable, and affordable service, they can't be beat! Mahalo for your outstanding service!
