Recommended Customer Reviews

This is a big company with many plumbers working for them. If you use them, request Doc. He is physically very strong, very knowledgeable and professional, and best of all thorough and responsible. He was very accommodating and seeing how he works, alleviated my fear that I will have future problems.

We called regarding 2 plumbing problems. They said they would CALL before coming over. They did NOT. When the plumber arrived, I told him to come back when we could stay for awhile (we only had 20 minutes) as I didn't want to pay for two trips. He said he could get them both done in 20 min. He couldn't. I told him we would not be paying for a second trip, but he came back and charged us for a second hour ($104) even though the TOTAL for the two trips was way less than one hour. And I had told him in advance we wouldn't pay for it. I sent in my check, subtracting the $104 from the bill. Never heard anything. Now, over one year later, I get a bill for the remainder!!! Ii would never use them again.

This company is professional and honest. Dante is awesome! They fixed our AC so fast. We always call this company for repairs.

Great job finding a slow leak from a unit above mine. He was also very patient w/ the idiots that live upstairs who did not think they could afford the $300 repair!. They really did not have a choice after it had been leaking for a month & they had been very evasive. He did a great job of covering the job w/a trap door. I will need more ceiling repair work to fix all of the peeling paint etc. He was on time, early even & worked very efficiently & did an excellent clean up job , even vacuuming the hallway where some of the ceiling dry wall was tracked. Our condo bldg uses them all the time. Thanks!

We had several items that needed fixing at our home that required multiple service dates. Our first plumber that came out to the house was stellar his name was Doc. The third plumber at our home seemed to have altered the work order for a service that was not completed.
When I called the billing office no one seemed to care that we were over charged. They asked me to write an email and no one even bothered to call back.
I have been calling them since (4'xs) they over billed us in July of 2018. I have spoken to the same customer billing person Theresa N. and each time I call she asks me to send in my invoice number via email. She also acts as though she never spoke with me when as she requested I sent several emails. I last contacted her in September and sent yet another email attaching the incorrect invoice that they billed me for.
Forget it. I'll suck up the additional charge for work that was not done and let everyone I know what a less than standard company this is due to their customer service and billing office.

Called and left a message at 5pm for a shower that was not working. Phone call was returned first thing the next morning and plumber had the problem fixed by noon that day! Super professional reception, thorough and efficient plumber. Much appreciated Alakai! Saved me a lot in time.

With recommendation from my building manager, I had service done in my master bath. The quality of work was okay, but...
Not so good: BILLING! I had to wait ONE MONTH for the bill! Before the work started, I had to give them my credit card info and was told that was how I would pay. So why it took so long to figure out a simple shower part replacement is beyond me. Even when I called the billing department, I got the "end of the week" time frame for a copy of my bill (that "week" stretched to a month!) Other companies who repaired my kitchen and bathroom plumbing all presented me with the bill on site and I was able to pay them before they left.
Also, I read the invoice and was suspect of a charge that was totally inflated and might even be false. I called the billing department and, of course, nobody answered. So I was taken to voicemail. I left a message, asking them to call me regarding certain discrepancies. Sadly, I won't be surprised if I don't get a callback soon. Oh well...no callback, no payment which, by the way, was almost $800 to replace a part in a shower!!!
I also just read the recent Yelp reviews and I wish I had known about these before I hired Alaka'i. Agreed: Alaka'i is overpriced...WAY-Y-Y-Y overpriced for the customer service you receive.
Never again will I hire this company. Other plumbing companies whose prices are lower and the customer service is way better than Alaka'i have my business from now on. Lesson learned. An EXPENSIVE lesson!!

Called them about replacing a low boy water heater, they said sure we will come down and that they had opening this week. I told them no rush, not an emergency and that I wanted to get a quote. They said Oh a quote, well that will take a couple of days... well its been a week now and no quote. Guess they only want to do emergency work so they can charge me arm and leg.....cause no one wants to shower in the cold...

Had some plumbing that required a licensed plumber in my condo. Called this company and the estimate was very affordable, so decided to go with them.
Technician named Darren came up to do the work and he was freakin awesome. He did everything we wanted plus some small work in the time they estimated it in. This guy was a hard worker and he really came prepared. The quality of his work was great and I found no flaws.
Pros:
Affordable, easy to schedule, on time, comes prepared, works efficiently, and great communication.
Cons:
None
Definitely will do business with them in the future and I'll recommend everyone to use them.

Horrible experience with this company. Make sure to have someone there watching the start and end times of the workers as they pad the hours BIG TIME. One job that literally took 20 minutes showed up on an invoice as being billed for 1.5 hours. Keep a close eye on the arrival/departures or you'll soon see an invoice with a lot of workers having billable hours of 8 hours a day, which you won't see on the iPad they give you to sign. Make sure you know what you're signing on the iPad too as nothing is filled out. They technician can verbally tell you anything they want while obtaining your signature, but what you receive in the mail doesn't match what was actually done at the time of service.
The caliber of plumbers we had were varying in degree of expertise and if the issues we were facing weren't so dire, you'd almost have to chuckle & think many of the scenes between them came out of a comedy movie because no one was on the same page, as they bickered back and forth how the job should be done. Metal pieces of pipe were left behind where it was accessible on the floor where an infant was crawling, toilets were taken off and left exposed overnight without being covered, holes were dug unnecessarily, and many other disturbances.
The real nightmare began when we purchased a brand new hot water heater, that's obviously leaking by the water marks down the front and the RUST ALL ALONG THE BOTTOM RIM OF THE TANK (which our solar tech pointed out - thank you, thank you, thank you). Attempts to try to get it replaced have REPEATEDLY gone on deaf ears. So even if you purchase brand NEW equipment, which comes with a manufacturer's warranty, they do not want to be bothered; they only want your money from the initial sale. Avoid this company at all costs. You'll only get superior service if you're a multi-million dollar condo building or hotel that gives them hundreds of thousands of dollars a year.
