Hugo did it again! I had a bad clog in an office of the commercial building I manage and Hugo came out with the hour. He cleared the clog and showed my tenant how to clean out the filter so we won't need to call him as often. He's reliable and honest! read more

Our home is 60 years old with a small under house crawlspace , we had a several leaks in the drain system and a broken line under the tub and shower , Diamond arrived on time was courteous . informative and did an amazing job replacing and updating all drains and vents , job was more work than they bid but he didn't change the price at all , i highly recommend them read more

I called Hugo for help with a leaking upstairs tub that was causing problems with my living room ceiling below. Hugo came out a few hours after my call and spent a meaningful chunk of time diagnosing the problem. He determined that the issue was not plumbing but waterproofing (grout, etc.). He refused payment for his time helping me. He is honest and easy to work with. You should hire him if you need help with plumbing. I am a harsh grader and he receives an A+ from me! (By the way, I also called another "highly-rated" plumber when I called Hugo. The other company quoted me an over-the-phone estimate of $600+ and were unable to come out for a week!) read more

Hugo was great, he was polite, professional, easy to communicate with, and did an excellent job. His communication every step of the way was exceptional, I always knew when he was coming, approximate arrival time, and he finished within the time he said he would. Unlike other companies I have worked with, I did not have to waste hours and hours waiting on people to arrive etc, this was one of the most efficient uses fo my time. I would recommend them in a heart beat, they were half the cost of other companies i get quotes from, and they even did an exceptional job of cleaning up after the work was done. If you have any plumbing needs I would highly recommend them. We have a gas fireplace to install and will be hiring them again to do the work. read more

This is the second time we've called Diamond for unexpected issues and we now have them saved in our contacts. I texted after hours and Hugo got right back to me, asking for photos and then came out within the hour. They are prompt, adhere to COIVD guidelines, fast, integrity is their jam... Hugo explained the issue, his solution and was backing out of our driveway in less than 30 minutes. The price is fair and he gave us things to look for in other areas to prevent future issues. This team is THE team. read more

MY GOD! I called them at New Year's Eve , they responded within 10 mins, came over within an hour, got my flooded toilet issue resolved and fixed the back garden flooding too. It was raining horribly at the time when they were fixing it when there is pouring rain I really really appreciate their work and would like to HIGHLY HIGHLY recommend their service . Thank you Hugo and Angel for ur work! read more

I had called one company who came out next day, then let us know they charged $250 to snake a short drain. Basically a half hour job. No f'ing way. I called Diamond plumbing instead. Should have called here in the first place. Hugo came out to give an estimate, and handled the clogged drain at WAY less than the other company. Quick, reasonable prices, friendly, professional. What I look for in a business, and what this company provides. read more

Thanks Hugo for coming through again and helping my mom on such short notice! You are amazing and do a superb job everytime!

Been having problems with drainage since like November. Had several different companies come out but only helped with short term fixes, so wanted to try someone new. Hugo came by and was the first to put on a coverup and dive into the crawlspace. He discussed several options and took pictures with his phone. He confirmed leaks as we turned water on from different parts of the house. He was more than willing to help breakdown the project in doable sections and came out the following weekend. He and Alfonso rerouted waterlines for the kitchen/laundry and troubleshooted to avoid more labor. He was willing to teach and show how to fix an additional problem but I decided to jus hire him again and he came out to fix the original problem that left a big hole in my sunroom. In just 3 visits, he has fixed problems that have been sitting for years. Thank you, Hugo. You've been a lifesaver. read more

Can't emphasize how happy I am that I called Diamond Plumbing!!! The person who came to help was nice, incredibly respectful of our property and of the ongoing public health issues! They also not only got the job done, but they were also thorough in making sure our pipes were unclogged, and in explaining what had gone wrong. They went above and beyond, had very reasonable prices, and didn't try to upsell me or pressure me to add any unnecessary services! 10/10 will ABSOLUTELY be giving them a call next time something goes wrong. read more

I have a clog with my outdoor patio plumbing (which is about 20-30 years old I am guessing). I was referred to Hugo by another plumbing company. Hugo came on time and friendly. He did a scope first to assess the problem and then he tried to snake it to clear the clog. Unfortunately the clog didn't get fixed not because Hugo didn't try, it's because the clog is probably too bad and it's further down the line. I am giving him a 5 stars b/c he was VERY polite, professional and patient. It's hard to find people like this nowadays. I would recommend him to anyone. read more

I recently had the worst experience with Hugo and will definitely never use them again... he's very disrespectful and can't seem to understand facts with reality... I'm disappointed 100% ... over charges for A ) issues that aren't 100% done by his employees or him .... can't seem to respect others in their own home and blames his customers for his mistakes...don't use or bother with this company... God bless read more

Hugo responded to my Yelp quote in about 15 mins of submission (I also asked for quotes from 4 others in the area but Hugo was the only one to respond and he was the initial person I wanted to work with due to Yelp reviews). They were in Walnut Creek and told me they would come for a FREE estimate on my rooter service in about 30-1hr. They came in about 20 mins to the door and was very polite. He was conscience of the shoes on the shoe rack and started to take off his shoes before coming in the house. I showed him around and the issues I was having. He gave me a quote and I agreed. He was able to fix the issue in about 15 mins (I had been working on it myself for 2 1/2 hrs already). He gave me recommendations to help prevent this and tips on what I can do myself. Overall: Hugo and Alfonso were very polite, professional, knowledgeable, and solved the issue in a quick and non-destructible way. They definitely under promised and over delivered. Their price to fix my issue was very reasonable and would continue to go with the them. Thank you guys. You saved my weekend! read more

Called with a burst pipe under my house, they arrived within 10 min, went under the house, gave me a reasonable quote within a few minutes and had it fixed in about 90 min. Alfonso was a super nice guy, very professional & explained everything thoroughly. I couldn't recommend him enough. Great experience and I will def be calling again if/when I have any plumbing needs. read more

Hugo Cruz is the best!! He spent almost an hour trying to fix my plumbing problem and the issue is under the house...crawl space is inaccessible because of rain. Clean out is one way and I have no money so Hugo did everything could think of at a very reasonable fee. Nothing! read more

Great and fast service. I called Roto Rooter the day before and they couldn't find any techs to work. I called Diamond the very nice dispatcher said the plumber would be here within the hour. He was here so fast. He found the problem quickly and was able to clean the drain very easily. I highly recommend Diamond Plumbing and Rooter. read more

This is my second 5-star review for this business. Returned from travel to discover my garbage disposal was not working. Hugo made a space for me in his schedule. Came out on time. Got the job done. Charged a very fair price. I have referred this business to friends - solid expertise, trustworthiness, fair, and responsiveness. Hugo and Diamond are my go-to plumbers now. read more

Our shower valve broke, and we had to turn off all water to the house. I called at 7:15 am and spoke with Hugo; Alfonso was there in about 2 hours with the right part to fix the shower. He told us the price, and finished the work in about an hour. They were very communicative throughout, very happy with their service. read more

My go to guy!! I contacted Hugo, and let him know our toilet was in- he got right back to me, and prioritized my needs and my toilet was installed immediately!! He's such a great guy... highly recommend. read more

You don't meet many people like Hugo. This man is a lifesaver I cannot stress this enough. I've been using his services for routine maintenance for sometime, but with a major leak in front of the house, this was anything but routine for me. He showed up when he said he would. He explained everything. He told me what my options were. During his inspection under the house, he discovered another major plumbing issue and took video of the problem so I could see it. This was far worse than what I had originally called him for. I don't know when I would have ever found out about it, but this man has saved my life. He is professional, kind, detailed and he worked with my budget. He answered all of my (no doubt stupid) questions. I can not recommend this man enough. Thank you, Hugo!! read more

Awesome plumber. Only plumber I will ever use in the future. He was prompt and very honest. I had a stoppage about a year ago, but that plumber did not tell me root cause of the problem. So I had another stoppage two days ago. Hugo cleared it and came back today in the rain to fix the backflow pipe. He showed me that it had been installed incorrectly which is why I had the recurring problem. Knowing a thing or two about construction myself, I could see he knew what he was talking about and was honest. Then he showed me how he corrected the problem before covering up the pipe again. I can't say enough great things. read more

Probably the best plumbing experience I have ever had. Our sewer line backed up due to roots underground. Alfonso arrived within an hour of making the phone call. On a holiday. He was extremely professional and thoughtful. Cleared the pipes and gave me a detailed explanation of the work completed. Highly recommend!! read more

Hugo is honest and responsive. So lucky to find him. Even though I called him after hour as an emergency he told me that it could have waited so we don't have to be charged for an emergency service fee. He is on my contact list and I would definitely use them again for Our plumbing needs next time read more

Our sewer line was backed up, and I had a number of other issues that I had been wanting to address so I called Diamond. They had an opening for the next day. Hugo came out in his very nice van, put on his shoe covers and came in the house to check things out. We went through three issues that were things I found I could fix myself. The sewer line cleared itself out after I ran the tub and flushed the toilets. So after 30 minutes, he picked up his things, and wouldn't accept any payment since he "hadn't had to actually done anything." Me next plumbing issue or request for a plumbing referral is definitely going to Diamond. They've earned it. read more

had a horrible time dealing with an old valve under my sink while i was installing kitchen faucet. tried my best but i couldn't get it off. after a couple hours of trying i finally gave in and called Diamond Pumbing at 3:30 on a thursday. Hugo arrived at my house within an hour and got everything working in a jiffy. nice guy, very courteous about shoes inside/wearing mask. didn't pressure me/try to oversell me. he was also great giving about advice for future problems. if i have ANY plumbing needs in the future i won't hesitate to give Diamond Plumbing and Rooter a call. read more

Highly recommend this company. Both Hugo (owner) and Alfonso (technician) were very helpful. They were efficient and thorough. I found them on yelp originally. Hugo had someone out to service us immediately. Thank you guys! We'll be making sure to do business with you guys again. read more

The hot water died on me at the beginning of the week. So I contacted the company via yelp on Thursday night and Hugo responded promptly. He ordered the part And was able to come and fix the heater in the afternoon. Since the parts are still under warranty, he took the liberty to call the manufacturer and ordered the replacements. He will come and pick them up tomorrow. Not sure how much other company charges for such issue, but his service is surely worth the money. read more

Hugo is legit and a good person. He came a day early. Took care of all the issue. He is proffesional and honest. Dont look for elsewhere. He has a customer for life in us. read more

The reviews are correct! Diamond Plumbing has earned their 5 stars! Professionalism and great service on a tough job. Hugo sent Alfonso out to help me with a pinhole leak in the copper pipe in the crawl space under my house. Not an easy job to begin with. Hugo quoted a 2 hour window and Alfonso showed up about 20 minutes later. He diagnosed the problem, explained his Plan A, and Plan B, scenarios ahead of time, and just put on an extra shirt and took his tools under the house on the spot. I held a flashlight on the pipe from outside the nearest vent, hoping I was helping with light, and not trying to "play supervisor". In turn, Alfonso and I had a running conversation about copper piping, soldering vs crimping, working in crawl spaces, etc. That's what I like in a craftsman; professional and a personal touch. And the charge was exactly as quoted. The leak got fixed in 2 hours by Diamond Plumbing, after I had waited two days for another company to tell me I had to wait another day for a different guy! We could finally run the dishwasher, shower, and OMG, flush a toilet! Thank you Hugo, Alfonso and Diamond Plumbing. I now have a new plumber service posted on my refrigerator! The card reads: "We charge by the job, not by the hour!!" read more

Hugo and Alfonso You were amazing You responded to my 9pm call Called all over the place to see if parts were available to fix my aging water heater Helped me decide that it would be more cost effective to replace it with a new model And were available to do the work right away Plus you explained everything and even showed me how to sweat copper pipe Thank you so much I would recommend you to anyone who needs honest quality work, good prices, and great customer service Thank you Debra read more

Called Diamond Plumbing to see about installing a water shutoff to the sprinklers, since we seemed to only have one, that shuts off the house and everything. They came out, looked around, and found that we already had one, cleverly disguised on the opposite side of the house. No charge, and they were friendly and informative. I will surely call them next time we have any plumbing job. read more

We contacted Diamond Plumbing for our bathroom issues on Friday 7am and they were able to send a plumber to our house at 9am the same day. Hugo was a very knowledgeable and a kind plumber. He took care of everything professionally. He was wearing his mask before he entered our house and he kept his shoes covered during his stay. We truly appreciate their professional service. Thank you! read more

I want to thank Hugo for coming out to my place last week and gave me great recommendation on my sewer lateral to the city. He carries a wealth of knowledge and will even help walk you through to the best decision for your house. I am thankful to have met such a great person. Thanks again Hugo! read more

Great service! Hugo was super thorough and explained everything going on with my plumbing issue and how much it was going to cost very clearly. Super appreciate them taking our job 2 minutes before they closed and going above and beyond to make sure the job was done right. Will use again. read more

This review is long overdue. Hugo is super nice, extremely helpful, professional, punctual and he provides top quality work. He fixed our major clogged kitchen and bathroom. I would highly recommend him!!! read more

When my upstairs neighbor sprung a leak, on a Sunday of course, these guys came out within the hour to assess the issue and immediately replace the faucet. They even went out to Home Depot and FaceTimed with my neighbor to pick out new fixtures before installing. read more

We called Diamond Plumbing around 5 o'clock in the evening, hoping to get an appointment within the next couple of days. Hugo came out that night and gave us a quote! He was extremely knowledgeable, personable, professional and competitive. The next day Hugo and Miguel arrived and went straight to work fixing what needed to be fixed. They not only did an excellent job, but you never would've known that they were there as they cleaned up after themselves so well. There is a real pride of workmanship with Diamond Plumbing, something that is sorely lacking these days. I would not hesitate to recommend Diamond Plumbing and Hugo and Miguel very highly to any of my friends. read more

We just discovered a clogged sewer line. It is Saturday afternoon, we are still recovering from Thanksgiving festivities. Called 3 plumbers. Diamond (Hugo Cruz) called back within minutes. Hugo said he could help and would be here within the hour. He pulled up to our house about 25 minutes later in a well maintained and marked company step van. Hugo told me his rate, told me what he'd be doing and was done within 15 minutes. The rate wasn't the lowest but was completely reasonable given the prompt and effective service. Hugo will get the first call anytime we need plumbing assistance. read more

I phoned the company and received a call back very quickly. Mr. Hugo came to my house within an hour or less, on a Saturday no less, and immediately surveyed and diagnosed the issue. It got fixed within five minutes at a very reasonable price. Once here, I sprung a second plumbing issue I was having, which I hadn't disclosed when I first phoned the company, and Mr. Hugo good-naturedly and expertly took care of it as well. I was highly impressed and recommend this service without reservation. Thank you, Mr. Hugo, for allowing me to wash my dishes in the kitchen sink once again (not that I look forward to this chore!). read more

This is a delayed review, but I got to commend Hugo. I had an issue with my mom's refrigerator leaking, and though he didn't end up coming to fix it because it turned out to be something the warranty covered, Hugo spent time to talk me through the possible issues over the phone. No charge. No attempt to try and get me to pay for something I didn't need, but simply because he was trying to help me out. I know if I have a future plumbing issue, I'll be sure to use him because he showed me was honest and willing to go above and beyond that day. read more
