Recommended Customer Reviews

Diamond Head Plumbing plumber has visited us over a week agao and inspected our house and hasn't still heard a word about the estimate. I do not appreciate it at all.

I couldn't be happier with these guys service. While in Hawaii, our timeshare While in one of my multiple visits to Hawaii, our apartment needed to be fixed. We were looking to get different quotes from different vendors but you know how hard is to find a good and reputable company. My hat is off to Cooper and his team. Will definitely do business again!

Called them on President's Day holiday and was surprised that they were open. John came out to my house within an hour to fix my shower faucet handle that was stripped. He was pleasant, courteous and professional. Thoroughly explained the problem then proceeded to get the job done. I feel that his fee was fair and the best part is that he didn't charge me extra due to the holiday. Diamond Head Plumbing will be my first choice to fix my plumbing problems from now on.

They did good work but Mariella is one of the rudest people I have ever had the displeasure of coming across. They screwed up the sending us billing by having the email wrong email information. claim they sent this to Bill 2 ,, HMM when it bounced back.. MAYBE A QUICK CALL WOULD HELP OR even mailed the bill???? NOTHING.. they finally called and she was SO RUDE rude and I had to actually go down there in person and pay the bill because she threatened to send it to a bill collector on my and my wife for not paying a bill that we never got the bill for. I'm sad to say that I will never use them again because I will never want to support a company that hires such a rude person and blames use for there mistake....

I have called Diamond Head Plumbing at least once a year--as I am renting in an older house. Every time I call, they come on time and are able to schedule me in within a few days time. I had to turn off the hot water to my house, as it was running and wouldn't stop. The plumber came in and bought a new part for it. I forgot to ask him to check the cold water faucet, but he was already planning to buy two sets and replace it for me. Unfortunately, there was only one in stock. He was also kind enough to help me look around for my cold water shut off--just in case a similar incident occurs with the cold water. The previous time I had a plumber come over, he unclogged my tub, which was the main problem. I didn't ask him to, but he also unclogged my bathroom sink, which was really helpful, as I didn't know how to disengage the sink stopper and pull it out. In both instances, the plumbers go above and beyond what was expected, and I really appreciate that. They could have easily left it and it could have profited from another house call. I've had only great experiences with Diamond Head Plumbing and will continue to use them.

I have an old house that had a bunch of plumbing problems. Peyton came out and was terrific! He assessed the problems, and quickly fixed the easy ones. Then he tackled a serious problem at my main water entrance. He called BWS and got them out at once to repair my meter. He had to dig under a fence footing in pouring rain to relocate my pipe. He had to deal with a neighbor -- who was clearly wrong -- but continued to harass him. He was friendly, knowledgeable, and tactful through it all. By the time he left he was drenched, muddy, and tired, but still had a big smile on his face!

My sink pipes literally fell apart last night. My property manager said she couldn't find a plumber until nearly 48 hours later; that was not acceptable to me. I took to Google and Diamond Head Plumbing popped up. I called and the receptionist, Mariella worked me into the schedule an hour later. She was so kind and rearranged their schedule to take me. Peyton was my plumber and he was prompt, knowledgeable and efficient. He explained everything to me and he absolutely gained my trust. I expected the job to take a long time, but he had everything completed (shopping for parts, fixing the problem, testing the pipes) in 2 hours. I was able to make my work appointment without any disruption. I highly recommend DHP to everyone!

DHP is the best. I thought I could replace a 60 year old valve myself, but I couldn't get the old crusty one free. Cooper and his team not just helped me with my DIY questions but then again when I failed and needed a pro's (Kevin's) help to do the job properly. I highly recommend this very professional local company.

It's daunting to hire a plumber without really knowing what your bottom line price is going to be. That being said, I was given a pretty good approximation over the phone of the time it would take and the hourly rate. The good: Other plumbers I called were booked and couldn't schedule me in for at least a week or two. One guy told me he needed 6 weeks notice! DHP was willing to come the next day if I needed! The plumbers that came (Kevin and Colton) were friendly and personable. When the resident manager failed to shut off the water at the planned time, they were also very patient and worked around it. The work was well done, professional and neat so I do thank them very much. Okay now for the bad: Whoa, quite a mark up on the parts! A valve at Home Depot that would cost $25 at best was billed $97. A connector was more than twice the price I would have paid at the hardware store too. But I suppose that's the price you pay for convenience. Thankfully, I didn't need too many parts so I'm not going to be too upset about this. If I had the parts available for them to install, I'm sure they would have used them and I wouldn't have gotten charged. Lesson learned. So if you have the time and a little bit of foresight into what might be required, maybe prepare ahead of time. Also, get a total $ estimate if possible instead of just an estimate of the time required, just so it's very clear. Of course, they can't be held to it if there are unforeseen issues I suppose but if everything goes as planned, you can at least know what to expect to pay. I would use DHP again and will recommend them to others. Though I would probably only recommend Kevin and Colton since they are the only ones I have had experience with. I called DHP to let them know that their guys did a good job. The mark up on the parts has nothing to do with them so 5 stars for the labor and 2 stars for the parts...I'll give an overall of 4 stars.

Forget these guys. Over rated and overpriced. At $110/hr it is not unexpected to assume they are trained properly to performed basic tasks. I wish someone would pay $110/hr to futz around in my kitchen. At $110/hr wages you are stating that you are a specialist in your field and that you are somehow deserving of this 10X minimum wage rates. It takes you 1 hour to do a 1 hour job. Simple enough yes? So how do you justify needing three times the amount of time? So at Diamond Head Plumbing a true specialist would need to be paid $330/hr to get a 1 hour job done in required time. This is tantamount to ""switch and bait"" practices.... Give one quote over the phone, get in the client's door and rack up them $110/hr's. At least Lawyers had to go Law school to pull off this kind of S#17. Seriously, unless your job is being paid for by insurance stay clear of these guys.
