Recommended Customer Reviews

Hawaii Plumbing Group did work in my building recently, replacing piping. Do not use this company if you are planning to do similar work. Your tenants and legal team will thank you. My building could not have chosen a worse contractor. In my own experience, they've stolen personal property, left a mess EVERY SINGLE DAY they've entered my unit, and they've failed to correct damages to my unit. If ever you work with HPG, do not expect any level of privacy to be honored. They look through your things and, unfortunately for me, steal my own property! Also, every day they enter my unit, I've had to clean up after them. I'm no clean freak - all it would take is a literal minute of vacuuming or wiping down the unit, but even that is apparently too much for these guys. They just do not care. Simple as that. When it came to corrective work, they'd do the easy things, and ignore any other items. Even when there was clear proof that they caused damage, they did nothing if they couldn't correct it in a few minutes. For us, it was much less of a headache to let things go just to get them out of our unit. AVOID THIS COMPANY AT ALL COSTS. Thank me later.

My sister had a quote to do re-piping from her house to the city sewer line. I called Kimo at Hawaii Plumbing Group and found out that the first quote was very exaggerated and bordering on a scam. Kimo sent his team out there and took care of her re-piping at half the price and done very professionally. I would highly recommend Kimo and Hawaii Plumbing Group to do your re-pipe or general plumbing projects.

Follow-up to my last review: Rick and his assistant did a phenomenal job repiping my entire 3/2 SFH. Project required all galvanized water piping and cast iron sewer piping to be removed and replaced with new materials. As an added bonus, the home's water and sewer systems were returned to full operation at the end of each work day thereby eliminating the need for my wife and I to find alternative housing during the project. If you are considering repiping your home, then I most strongly recommend you contact HPG for a consultation and quote. This is the 4th time I've used HPG and my wife and I couldn't be happier with HPG's customer service, affordability, communication, craftsmanship, etc.

This business and it's employee's deserve an infinity star rating for their honesty and character! This morning I dropped my wallet somewhere out side Joes Grill Express in the parking lot and one of the HPG Crew members found it and turned it into their office manager who call my BOH Office and had them contact me! I called Margret and she explained what happened. I met her at the office and she handed me my wallet fully intact! God bless this establishment! The Aloha spirit is well and alive here on Oahu! You can be sure whenever I have a plumbing need in the future, I will contact the Hawaii Plumbing Group! Thank you for your Honesty, Integrity and for saving me from a disaster!

When i got my estimate from shaun the ac guy he had excellent customer serviceand knows his shit and gave me an awesome estimate. I would definitely recommend him to everyone of my friends. Hands down excellent guy!

This review is for the HVAC side of HPG. Installed the Mitsubishi M-series split system about six weeks ago. Two compressors and five air handlers. It was a pleasure working directly with the owner Kimo upon referral from a friend who had recently installed a single split system. I was very pleased with the attentive response from HPG as it was he start of the busy time for AC installs. Many other Diamond contractors were difficult to get a hold, didn't respond, or seemed to be in it for the sales. HPG spent the time to discuss the system layout, cost, and to address concerns and make sure the customer was satisfied with the work. I believe HPG had about a year as a Diamond contractor, however their HVAC crews had decades of experience in the industry as installers. It was less than two weeks upon signing contract before starting work. Installers were very courteous and let me know when they were arriving and departing the work site. Installers discussed their plans before making penetrations in the walls. Installers took pride in their work and paid attention to he details for a neat and clean installation. Upon completion of work they quickly addressed an issue with one of the air handler's mounting plate that came off of its wall anchor. I'm glad to have the system installed and have been actively using the system during this hot and muggy summer. System performs well as designed and is very quiet as advertised. I look forward to continue working with HPG to provide maintenance services on my system. I have since referred a friend to Kimo who is currently having a system installed there.

My experience with HPG has been through Peter. He is the project manager for the repiping work at my rental property, a 45 year-old high rise apartment. Initially I contacted Peter to file a complaint. Peter was patient and non-confrontational even though HPG was not at fault. Over the course of the project, he is responsive and professional. We communicated through phone, text and email. The company sent excellent communication in advance and provided advice and resolution on an electrical issue unrelated to the project. They set the standard for customer service!

This company did work on the Apartment building my husband and I were living in, in Hawaii, and it was one of the most miserable experiences we have ever had. They made our life a living hell for three weeks. We had one usable bathroom at all times, which was okay, but every day we would have to come home from long days at work, to clean up their mess. I would have to vacuum and wipe up mud/dirt from our bathrooms, and put the shower curtain back up every single day. We also had to walk on dirty plastic wrap and nasty cardboard for a month, which they didn't even remove before a weekend. It was so unprofessional, we just couldn't believe it. But the worst part of it was, we left a review on Yelp because of the experience, then the owner had the audacity to bribe us to take it down! I took it down because my husband being in the military, he wasn't home every night, and I felt it was safer to just take it down so they would stop bothering us and making a joke out of our experience. They also broke our bathroom mirror, which took a week to replace, and I had to actually ask them where the mirror was after they were done working. Then they told me the broke it... no one told us three weeks before when it actually happened. Just a badly managed company... I'm so glad we don't live on island anymore, so we don't ever have to put up with this plumbing company again.

I have always relied on Yelp to get the feedback when I need to find out how good a restaurant really is or a place where I plan to conduct business. I am writing in to compliment the workers and the Management team at the Hawaii Plumbing Group HPG. My condominium apartment was approaching 45yrs old, and our Bldg Association forewarned us owners last year in 2015, that a complete internal plumbing retro-fit would be needed in the Spring of 2016. It was something I was not looking forward to because other friends had told me as to how invasive and inconvenient it would be. I am here to tell you that HPG, and their Team of competent and skilled workers displayed the kind of professionalism that I thought was long gone. Any questions or problems was handled properly by site HPG Manager ""Peter"" who made things right. Yes, the work required involved a lot of hard work, cutting into walls, drain pipe removal and their replacement, Finally , to replace and repaint, the removed sections of drywall, and the reinstalling all of the bathroom fixtures, ie vanities, and mirrors. I'm here to say, that all of that was done, with special care not to damage any of the home furnishings in the unit, and to leave each day, only after the work was performed satisfactorily, and the area cleaned up completely.The total work was done in less than 9days. My sincere appreciation and thanks to the Hawaii Plumbing Group, I am happy to refer you.

Because we have an association we don't really directly deal with the companies our association hires for our building repairs and our grounds but yesterday as I was leaving to go out I actually got to meet Calvin & Kalani from Hawaii Plumbing Group who was hired by our association to repair our leaking gutters that's causing mold to grow on the front of our building! Not only is it an eyesore and makes our building look pretty ghetto but according to Calvin & Kalani, (who I appreciated that they shared a wealth of info with me)...we could see even more major damage happening if left in disrepair. Thank you Calvin & Kalani for not only repairing the leak on my exterior wall, for also sharing info and answering my questions, AND ESPECIALLY for going way over and beyond and helping this Aunty out when I locked my keys in the house! I can't tell you how much I truly appreciated you guys helping us out and witout any damage to anything! Lol Hawaii Plumbing Group certainly has good people working for them! Sorry I was on my way to appointment or I would've bought you guys lunch! Maybe your boss can do the honors? Thanks again guys!
