First Class Plumbing

First Class Plumbing

Ala Moana

Last night the pipe under my kitchen faucet burst and water started gushing out at a phenomenal…read morerate. I couldn't even figure out how to stop the water from coming out and within minutes water was pouring down the stairs and leaking into the floors below the kitchen. After calling everyone I could think of, including the board of water supply, with no one providing any help, I typed in "plumbers" into Yelp and started cold calling down the list. First Class Plumbing was the third company listed but the first one that seemed to care. I was warned that I was calling after hours so I'd have an emergency fee if I wanted service now... I joked "fine - this is an emergency" and was told I'd get a call back as soon as they could get ahold of one of their plumbers. I went back to trying to heave buckets of water into a nearby sink and received a call back 15 minutes later. The plumber was so calm, and after hearing that I was still dealing with gushing water, explained to me how to stop the water flow. He asked me to send him pictures of the burst pipe and the faucet and got off the phone to price everything out including replacing the pipes and faucet. After doing all that work he told me what the cost would be and then said it was no worries if given the price I didn't want to continue on - or at least wait until it wasn't an emergency (an extra $150 charge). I said I definitely wanted the service and he came right out and fixed the burst pipe. I would already have been raving about this place for their competent service if it had been a normal scheduled appointment. But the fact that this company and the plumber were there for me when no one else was, and went above and beyond walk me through how to stop the problems and extremely quickly look into part costs for me before I ever even agreed to the service has made me a loyal customer forever!

I reached out to several plumbing companies for quotes, and First Class Plumbing was priced right…read morefrom the start. I spoke with Ana and explained my plumbing issue, then emailed her a photo of the problem area. She quickly identified that it involved replacing my PRV, isolation valve, and irrigation valve. They provided a clear quote over the phone, scheduled the appointment within a few days, and completed the job seamlessly. Whitley arrived on time, was professional, courteous, and a pleasure to talk to. It was fun chatting football with him -- he comes from an impressive football family! His dad, Vili, was the University of Hawai'i football team's official Warrior mascot during the Colt Brennan era. Highly recommend this company for their fair pricing, excellent communication, and top-notch workmanship.

535 Plumbing - Busted kitchen sewer line pipe broken

535 Plumbing

Iwilei, Kalihi

My husband and I are retirees living in a condo in Honolulu. When our toilet was unable to flush,…read morewe didn't know who to call since our favorite longtime plumbing company was no longer in business. Then we remembered seeing 535 Plumbing trucks often parked downstairs and at other buildings nearby, and gave them a call. They asked my husband for some photos, gave him an estimate, and sent someone over that afternoon. The plumber was running late but kept us informed about when he would be arriving. Once he got here, he was very courteous, professional, and did what he had to do. He answered our questions clearly in layman's terms for us to understand. A second plumber stopped by briefly to help him. We paid what was originally quoted to us. We were very satisfied with the quality of work done and now have a new favorite go-to plumbing company to call on!

I've used them in the past many times at multiple properties, referred them to my family and…read morethey've also used them. Never had a problem until this time. I had them come out and do a camera inspection. The report says everything is all good. Nothing abnormal. Had a second plumber come out. Basically says that I need to completely redo my pipes because the plumbing is extremely old and falling apart with pictures and video After contacting 535 plumbing they asked what could they do to make it right. I told them that I'd like 50% back. They came back and said after careful inspection we cannot give you back 50% so I'm not really sure what they were going to do for me. Their process is extremely broken because at the bottom of the receipt and work order. It says that the line manager has the final say but I never got a call or email from the line manager saying that the initial report was 100% wrong. All I got was an estimate for replumbing the entire drains but nothing that said that the report was erroneous after having three other plumbers come out, which they all agreed the pipes needed to be replaced. I didn't get a video or pictures of the pipe. Only a small paragraph that said nothing abnormal noticed. I'm not a plumber that's why I'm paying plumbing companies to come out and do the work and I trust that they're going to do their best so I cannot be the one to verify their work. But but in the end I really need my plumbing to work and not feel like I'm getting taken advantage of. Eventually the owner caught wind of this and called me up. Credited me back $100 but I wish I had seen the reviews that this company has gotten in the past few months. I don't know if something changed there but I'm glad it's not just me that's dealing with this

Kawamotos Plumbing and Repair - Quick turnaround and good quality workmanship.

Kawamoto's Plumbing and Repair is the kind of local business you wish every contractor would be…read more From the very first message, they were professional, friendly, and quick to respond. I received a clear, upfront quote without any hassle. The work itself was excellent--fast, clean, and done right the first time. Chad treated the property with respect, making sure everything was tidy before he left. He even came out on short notice over the weekend without price gouging, which says a lot about his integrity. It's easy to see why Kawamoto's has such a strong reputation. Since 2013, Chad has built a loyal following by combining reliable service with genuine care for each customer. That personal touch really sets him apart. Reliable, trustworthy, and fairly priced--Kawamoto's has earned my full trust. If you need plumbing repairs or maintenance, don't waste time shopping around. Call them first--you'll be glad you did!

We have used Chad services extensively for both our personal home and a commercial property we…read moremanage, and in every instance, he has proven to be super reliable, absolutely professional, and incredibly fair with his pricing. He handles a comprehensive range of issues with equal skill. His work included everything from replacing old, damaged pipes to successfully clearing the most stubborn clogged drains. The best part? When we needed a new water heater, he didn't just replace the old unit--he recommended a hybrid water heater that has already started saving us a significant amount of money on our utility bills. This is a true professional committed to ethical, long-term solutions. Honestly, he is so good that we almost don't want to recommend him to anyone else, just so he doesn't get fully booked up and won't have time for us! But his professionalism deserves to be recognized. Look no further for a trustworthy and highly skilled plumber.
