Recommended Customer Reviews

We discovered a leak from our son's bathroom on Saturday morning coming through our ceiling on the first floor. Very upsetting to wake up to this on a weekend. We called Diamond House Plumbing, and a service technician named Jorge arrived quickly. He was very courteous and professional. He reviewed what he would be doing at our home (leak detection) as well as the cost. Jorge was very upfront and honest. We had a good experience with Diamond House Plumbing and highly recommend them to anyone.

I have a home warranty account, the problem is it's no good on an emergency basis. Diamond House Plumbing immediately answered the posting through Angi's immediately. Problem solved that very day of the emergency.

LIE, they say a free estimate they lie. They came for flooding dishwasher, said free estimate, said they would take a look. I was working around the house and let them do their thing. Later called me over said I had something stuck in pipe, and a tube just disconnected from the dishwasher so water was flooding out, so he just pushed it back in. I asked what needed to be done, if anything needed repair, they said no, he said he already fixed the issues and it would be 450 dollars!!!!!!!!!!!!!!!!! I said it was a free estimate and I did not agree to any work, or know any work was being done, I thought he was taking a look. They said I had no choice, that the smallest fee for their work was 450, but that the work would be warrantied for 1 yr. I was pissed and had to use my college class money I saved to pay for it. I was happy it worked again, but they lied, and told me I had no choice but to pay to an amount I was not told or asked about, or that they did work without telling me until after. I paid and refrained from leaving a terrible review as they fixed the very small issue. Then a month goes by and the same tube unattaches due to it not being secured, again, so I call them. They say they only inspected and did nothing, and the person who came out said the same thing. I said ""so I paid 450 for you guys to look at my dishwasher and do nothing? Then why was it 450?? I have a receipt and I was told their work had a year warranty, they said no sorry can not help you, unless we come out again and I said why so you can charge me 500 again to fix what you didn't really fix last time but charge me another 500, stay away. If you decide to give them a chance, keep an eye on them and tell them you will pay nothing without them asking for authorization for any repair even if it is just to push a tube down onto the nozzle to dishwasher. Be prepared to pay 450 which is what they told me was their minimum for their business !!! Lie NO FREE ESTIMATES, THEIR LOWEST COST IS 450 FOR NOTHING! I was not going to leave a review until they lied again and said tech said nothing was done or warrantied, even though I spent money I did not have to spend to pay for work I did not authorize because they said I had to pay it. Will be reporting to BBB. WORKER-

Diamond house plumbing is amazing and I will be going to them for all my future plumbing needs! They were kind, responsive, professional, informative, knowledgeable, empathetic to my situation, I could go on all day. They did an amazing job, and even after the project was completed, they are still so responsive and helpful to any questions or help that I need.

Sewer stoppage...
Diamond House fixed my problem very professionally...gave me choices for solutions. Worked out for both of us.

Hanz came out today, found problem without making big holes in the walls and found leak was coming from bathtub drains and be back first thing tomorrow morning to fix problem. Very happy with his service.

We had a wonderful experience with diamond house! They were very responsive, very professional, and very fair. I highly recommend Hanz Castillo.. he's the best!

I really wanted to give them a 5-star rating until they charged me nearly triple of what a repipe costs. 30k for a repipe I'm in awe... I'm stuck with a bill that's insane I'm just tired of companies taking advantage of a situation.

I had a leak coming from my upstairs bathroom into my powder room downstairs. I called several plumbers before deciding on Diamond House. Cesar came out and was quickly able to determine the problem (upstairs toilet leak) and give me 3 reasonable estimate options at no cost. Not only was he able to fix the leak, but he also repaired the ceiling drywall which had to be cut in order to do the repair!! I was also able to select my own toilet (which he picked up) to install which was very important to me. I was happy with the scheduling, service, communication and clean up.

Had new flooring put in and the toilets needed to be reset. Ulysses came out to provide a quote and was very professional and informative about what the job entails.
