Alakai Mechanical is the best commercial / multi-family plumbing contractor I have ever worked with. They have been my go to plumber for years, at Kahala Towers, Regency Park, and now the Commodore in Hawaii Kai. All properties had old / original plumbing. These guys are union, highly skilled, and always available. Condo piping is complex and these are the best in the industry in that regard, based on my experience with almost every plumbing company on the island. I am writing this review because I see a few negative ones on here which don't accurately represent this company. If you are a commercial property manager or owner, I highly recommend using this company.

TERRIBLE! PLEASE DO NOT HIRE THIS COMPANY! (This review is for Alaka’i Plumbing and mechanics) do not allow them to service your apartment/home as a 3rd party vendor or direct for anyyyy kind of service. Extremely disrespectful staff, Mike who is a foreman was awful to me and was so disrespectful he caused escalation instead of resolving the issue, so did Dale or Dan a customer service worker they have(can't recall the guys name). On one of their work orders the technician was super rude and disrespectful and made me highly uncomfortable, they operate as a third party vendor with my property management and they just don't communicate anything and slap you with an invoice that is supposed to be for property management to cover per my lease. Very scammy please be careful and try to do things on your own or go to another company!

We use Hi Tech for all our rentals in the local area. They do a great job and get us scheduled right away. I highly recommend them!!

On October 15 we needed help with our garbage disposal. The property had been a short term rental, and I assumed that the disposal had been abused into submission. I sure was glad to be wrong. Christian removed the right sized allen wrench from his toolkit, turned the motor from the bottom of the disposal, and unlocked the motor. Somehow in my infinite wisdom I have lived scores of years without knowing I could do this. Alakai could have easily charged me to replace that disposal because I did not know what I did not know. Instead I was educated so that I could repair something simple like this on my own next time. That means that Alakai Heating & Air Conditioning has earned my future business for all of their services.

Alakai costs a bit more but it is worth it. Experienced and will save you money on labor time.

I needed a backflow test done by October 22nd, and 2 plumbing companies that I worked with before, quoted me price increases which were double and triple from last year's fee. I decided to try Alakai Mechanical, and Darryl came by promptly and did this service at a very affordable price. Thank you Alakai Mechanical!

The most incompetent construction company on Oahu. Avoid at all costs. They charge insane prices for terrible work.

I have used Alakai for a few plumbing issues over the years and have always been satisfied. Last weekend, my garbage disposer crapped out. I called about 8:00 AM on Monday morning and was able to get an appointment for Tuesday AM between 8 and noon. Technician called at 6:30 AM and came right over with disposer. Installation completed before 8:30 AM with no problems.

They're my go to for plumbing issues.

Scope of work was to check kitchen sink for a leak and clogged bathroom sink and shower. The technician stated this on the invoice: "Prior to arrival on property made contact with the owner at which time had a hard time contacting tenant but arrived on property and was told if I could wait a little bit for owner to contact tenant. I wish I was finally able to get access to the unit." Long story short, I was charged for 3 hours instead of less than 2 hours of work. The technician claims the extra time came from calling the tenant to gain access and going from the unit to his van took 1 hour and 20 minutes. This was not the case, it only took him at max 10 mins to gain access to the unit to perform his work. Before hiring a plumber make sure you work with a company who can come see what the issue is and give you an estimate. If they cannot do this then I would avoid using that company. I've tried making contact with a manger on this issue but no response. Bottom line, I was over charged.

The guy came to fix my shower was friendly, but not professional at all. Why he needed to borrow WD40 & screw driver from me? And it was almost done in about one hour, then he decided to go to a store to get some parts. They charged me all those hours (3hours total). Women in the office are not very nice. They have poor customer services over the phone. Worst of all, my shower problem is not fixed after all. I would not recommend this company to anybody.

Not sure

Eddie I.
Be careful with this plumbing company and remember the hours of service. They tend to over charge. I know I'll never go back to them and will never recommend to anyone!

Alakai Mechanical was instructed to come to my condo through my management property company. They were only supposed to fix a leaking shower head. They had come a month prior to fix the shower head but only used tape to close the water shooting out and that didn’t work. So the second time they come to fix the shower head the plumber also sneaks in a charge for snaking my drain saying we have a clog at the condo. This is not true and the plumber “Doc” blatantly lied. We did not have a clog when we called the management property about the problem and we always use a strainer in our bath tubs. Alakai Mechanical is trying to charge me $235 for something that did not need to be fixed. Beware of this company. They have a lot of negative reviews and now I understand why.

I used them originally in 2012 and I thought they were ok. However, recently, I called them to schedule plumbing service two days from that time. After I got the appointment, I had to pay my condo management $50 to schedule water shutdown in order to do the repair. However, I got a voicemail with unclear message and asked me to call them back. After calling them without anyone knows what's going on, the next day I finally got through with them and told they cannot honor the appointment because no technicians are available. I asked them why they made the appointment the first place, but no one, including the boss, can get me a clear answer. I am totally fed up with this place and will never use them again. This is totally an unpleasant experience. I also urge everyone not to use their service.

I would be "very careful" using this company. We have hired this company in the past and they were okay, it's been a while and recently October 23, 2018 we hired them and the bottom line we were charged for what we felt wasn't reasonable. The working told us that he was going down to his truck to get a part and never showed up till 30-40 minutes later. We later found out that he left our property to get the part and yes we were charge their travel time to get the part. I wrote to their CEO and never got a reply back as we asked, a reply would be appreciated. It would have been nice for them to let us consumers that we would be charge in this case. As of this date November 12, 2018 still no reply. A complaint will also be sent to the Better Business Bureau.
