We have used Diamond Plumbing for a few jobs now: sewage backflow, broken sink, new hot water heater, and maintenance too. Hugo and team are always prompt, super respectful and never cut corners. The prices are fair and if they need to come back to fix something you can be sure they will. I recommend then to everyone! read more

We broke a pipe connected to our backyard faucet trying to take off an old hose. Called Detailed plumbing and Hugo Cruz came out right away. He fixed our pipe without having to go through our wall as he had originally thought he would have to. He was affordable and efficient, and he did such a great job I had him ( and Alfonso) come replace our faucet and water shut off valves in the front yard. Thank you Detailed Plumbing! read more

I talked to Hugo first about our low water pressure in the different parts of the house, he explain to me a few different scenarios and immediately assign Miguel to come over. Miguel was here within the hour , spend more than a half an hour, adjusted the water pressure and crawled under the house to check the piping . He was able to adjust the pressure evenly and explain everything about how to maintain it . These guys are great honest and professional and you can feel that right away. Highly recommend them . read more

Diamond Plumbing and Rooter - Plumbing Near Me - Concord, California

Can't thank Hugo enough for all his help when my parents had a recent crack in their sewage pipes. Hugo was very responsive and helpful. He came out after we had the mess cleaned up and diagnosed exactly what was wrong. He explained what work needed to be done and was honest about his pricing. He was fair and understood we had options. We decided to go with Diamond Plumbing and a lot of it had to do with the service provided by Hugo. He spent a lot of time explaining everything to us which we appreciated. Hugo also showed us pictures and on the day of the job, he sent more pictures to show his work and keep us apprised of the status of the work so we knew when we could start using the plumbing again. We are very thankful for the work performed and the service provided. The job was not cheap, it cost a lot but the cost was reflective of the extensive work that needed to be performed. Either way, please consider Diamond Plumbing for your needs, you will not be disappointed. read more

Called in the morning and Miguel came to our home before noon. After we explained the issues we were facing, he explained what he could and could not do. He could check for leaks in the crawl space for a set fee but he did not recommend troubleshooting the kitchen faucet as it may end be cheaper to purchase a new one and have it installed. After checking out the crawl space he clearly explained what he saw and what we could select for follow up steps. Good job. read more

Hugo was quick to reply and to show up to an emergency job for my commercial biz. We had a water leak in the ceiling and he worked with urgency to fix the issue. He has a special tool that he used to fix the copper pipe in little over 30 minutes. He provided the best recommendation to replace a 3 foot copper pipe that was 30 years old to prevent any future leaks due to mineral build up that was causing peep holes in other parts of the pipe. With his special tool, we did not need to keep the water off for too long which would have inhibited our neighbor commercial business to not operate. If you are a commercial biz or need a fix at your own home, call Hugo to get the job done right. read more

Super professional. Licensed. Gave a reasonable response window within 24 hours and was prompt and on time. Masks, boots, respect for our space and home. Knowledgeable about all our issues. Straight up with reasonable costs and what needed repairs. Advised us on what parts we could buy on our own to save cost and make sure we get something we like. I totally recommend Hugo. read more

Hugo arrived on time for our free estimate and was very polite--wore shoe covers and mask. Quickly diagnosed problem and showed us how to troubleshoot in the future (saved us from a more costly service). Also gave us quotes for some additional plumbing asks we've been meaning to get to. Highly recommend! read more

The plumber/company was an extreme pleasure to work with. fast , fair and efficient.

I used their service a couple times now. Alfonso is great, very patiently working on the tasks and willing to answer any questions. Will be the first one I consider for any future issues. read more

I contacted Hugo once again for a major clog issue because my home warranty plumber couldn't and didn't fix the issue with 3 tries. Hugo came out and within 15 minutes my clog was gone! He's a expert plumber and very easy and nice to deal with. I am going to have him replace my main next month. Thank you Hugo for a job well done!! read more

Heartfelt thanks to Hugo at Diamond Plumbing and Rooter! 5-Star PLUS Service and Professionalism - as a bonus you get the pleasure of working with an experienced, informative, kind, and sincere person! Every review was spot-on! Seeing my son's hands covered in black oily specks, after he washed his hands in his sink this morning, was disturbing beyond belief...My tub had been out of commission due to this same reason. During a pandemic who can you call for plumbing help? Hugo at Diamond Plumbing and Rooter! I had tried a few places close to my home in San Ramon but understandably, I didn't receive a call back. I am sure they might be short staffed or had very valid reasons for otherwise being detained. I did however receive a call back from Hugo at Diamond Plumbing and Rooter. He sounded like he might be in the middle of dealing with a current job and called back about 20 minutes later, just as he said he would. He was at my house about 30 minutes after our call. Every single 5-star review is 100% accurate. I own a local small business... Maintaining this type of personal and professional reputation really takes hard work, care, dedication, patience, and a huge amount of integrity. My water now runs clear! (Quite important to be able to wash our hands at this moment in time - stay safe everyone) One less thing for this mom to worry about. Thank you again! read more

Diamond rooter 5stars! Will find the problem, super nice guys ! Definitely will recommend for any future work! Hablan español también -Juan Residence inn Marriott hotel read more

Diamond plumbing has been out to my house more than once in the past couple years and they're always the best and fantastic of all of the plumbers I contact. Nice and fair treatment, reasonable pricing, always understand the problem, talk about the fixes with the homeowner and are competent, confident and knowledgeable about the work they do. Both times they've visited my home, once for a water shut off replacement and the other time for a cracked sewer pipe in my crawl space, they've come out same day, arrived in the arrival window they gave, and did a great repair. Communication, workmanship, responsiveness, and business practice are all great! read more

See all

Mr. Hugo Alvarado was punctual, honest, and knowledgeable. He told me how much to unplug the drain at the beginning. He charged me the exact amount after finishing. He sent photos of findings from the drain that might have cause the blockage. The photos were very helpful to me. Great job well done! I would recommend Diamond Plumbing and Rooter.

Hugo is amazing. I had my sink backed up on Sunday and I called him the next day and he was able to make it out this morning and mot only that he unclogged it and got everything done that same day. He is awesome and I truly recommend him. His rates are super reasonable. He is also honest and a hard worker. I normally don't post the reviews but he is the person to call for plumbing issues. read more

Needed a plumber & they came out within hours. Angel was nice, right on time, & took care of the problem. Affordable & great. quality.

It's not everyday you see good people who has integrity. I called Hugo for coming out to my place today for an emergency water heating check. He tried to save me money first by asking me to send pics of the problem and work with me on the phone to do a quick diagnostic. After he realized that this is not something I can do myself, he opened up his schedule so they can drop by right away. Hugo went to the house with Noe and did a great analysis of the problem. Unlike other techs, he told me the detailed problem and how I can analyze the issue if it happen again in the future. Again, Hugo with Noe will be my go-to tech for Plumbing going forward. They never try to "upsell" me but made sure that everything is good and safe. read more

We had a new fridge dropped off by another company and the install technician advised that our water valve for the fridge was striped so they were unable to install our new fridge. So we found Diamond Plumbing on yelp. They answered our call right away and came over within a few hours and replaced the valve so we could install our new fridge before the holiday weekend. Very professional and helpful. Would hire again in the future! read more

Miguel showed up within an hour of calling. Replaced a defective hose and faucet set. Everything was done professionally and was functional the same day it broke. Really appreciate the prompt response. read more

They called me back within minutes, showed up at my place within30 minutes of my call and my kitchen plug fixed in another 30. Very professional and follows health protocols. High recommendation. read more

Look no further, Diamond Plumbing is your best option, hands down. I had them come out for a second time (unrelated to the first time) for an unusual issue and they were nothing but professional and unwavering in their goal to fix the problem, all on the same day and at a reasonable price. I won't consider calling anyone else for my plumbing needs going forward. If you give them a call, you will not be disapointed. read more

Water heater went out Thursday night. Friday morning I called and Diamond was able to come out and inspect. Said I could replace parts for $XXX on an old heater or replace for about double and have a brand new one. He replaced the water heater that same day and was hundreds of dollars cheaper than the other quotes I got. Fast and efficient. Would definitely use again! read more

This is the 5th time using Diamond Plumbing, while planting a rise bush I hit and punctured the service line to my home, I called Hugo and in less than 30 minutes he was here to repair the damage I caused , it took the water district about half an hour ti arrive to attempt to shut off a stuck main valve , they ended up breaking it and had to have a crew come in to replace the meter and valve , Hugo's crew stayed on site till the main valve was replaced and water shut off then did the needed repairs , the work was done well and as usual with complete professionalism, the original estimated price didn't change even though they stayed on site for almost 3 hours waiting for the water district to complete their work, I highly recommend Diamond Plumbing read more

Diamond Plubing has helped with several plumbing issues we've had over the past few years. Every time, Hugo has been friendly and helpful, explaining what was occurring to cause my issues, and if possible how to avoid similar issues in the future. When I've had emergency issues like a broken water heater or a backed up sewer lateral, they have been very responsive and gone the extra mile to ensure that the job was done right. Because of that, I'll keep coming back for anything else that occurs. read more

Hugo was extremely helpful, especially during these times of social distancing. I called because my pilot light on the water heater continues to go out after lighting. I had replaced the thermocouple which didn't resolve the issue. Then I bought a gas control valve to see if that would fix the problem. After realizing it would be easier to pay someone than replace it myself, I called some local plumbers. The first person I called quoted a lower price than Hugo but didn't seem as knowledgeable. When I reached out to Diamond Plumbing & spoke with Hugo, I could immediately tell he'd be able to help. Hugo spent 10+ minutes on the phone asking questions to diagnose the issue. He even told me the process to replace the gas control valve in the event I wanted to save $. We discussed the precautions he would take entering my house because of COVID, & Hugo took all the necessary steps to protect himself & my family. Hugo also quoted me a price if we needed to replace the water heater. His price was only $100 higher than what my good friend (general construction) quoted for the job. I'll for sure use Hugo moving forward, & would recommend him to anyone who asks. read more

1/16/21 This is an update of a 5-star review I posted for Diamond Plumbing on 3/25/19. At the time I said I thought they were great and that I had found my plumber for all my needs. Unfortunately, since then, I've had two other contacts with Diamond, and now I realize I was completely wrong. The first thing that happened to make me realize how wrong I was, was in October, when I broke a hose bib on the side of my house, and needed the pipe repaired and the hose bib replaced. I called Hugo, and he sent Miguel out the next morning. After Miguel looked at the hose bib, he spoke with Hugo on the phone, and said they'd give me a break and only charge $695. I had no idea if this was high, but I wanted it fixed, and I felt Hugo would give me a fair price, so I said okay. From the moment he arrived until he left, Miguel was at my house for 1 hour and 50 minutes. He used two feet of copper pipe and installed a new hose bib. Afterwards, $695 seemed high for so little labor and materials, but I trusted Hugo, and let it go at that. Then, 10 days ago, my water heater started to leak (this had happened for for a short time in February, but stopped very quickly), so I decided it was time to replace it. My first call was to Hugo. His quote was $3450. The backstory here, is that when my water heater had first leaked back in February, I had asked him for a quote, and Hugo quoted me $2450. But apparently, Hugo had forgotten this, and so now that I was a repeat customer, the price went up $1000 in ten months. Because the price had risen so much, to see if Diamond was in the ballpark, I got NINE other quotes for the water heater, the low was $2295 (which I accepted); Hugo's $3450 was the second highest quote of the nine. Hugo later contacted me and offered to replace the water heater for $2800. Since I hadn't immediately agreed to his initial $3450 quote, he quickly dropped the price $650. But initially, he apparently thought I'd go for the $3450, probably for the same reason he charged me $695 for my hose bib repair. These quotes made me very suspicious of Hugo's pricing, so using photos of my original hose bib damage, I got quotes from other plumbers for exactly what Diamond had done back in October. The result - I got multiple quotes from $325 to $450. Wow - Diamond Plumbing had CHARGED ME $245 MORE than other plumber would have. And this after I wrote them a great review and said I would have given Diamond six stars, if I could. So, in these two contacts, I spent AT LEAST AN EXTRA $245 for my hose bib repair, and would have spent AT LEAST $505 ADDITIONAL for my water heater, had I taken Diamond's second, lowered bid. Well, now I feel like an idiot. I trusted Diamond and Hugo, and I said great things about them, even referring other business to them. Obviously, I was wrong; apparently loyal customers don't get good treatment, they get high prices. I sure did. 1 star, and if I could, I'd give them 0 stars. Think twice about what I've written, before you become a customer of Diamond Plumbing. read more

Thank you for responding so quickly to my call. Hugo answered the call and sent a technician who fixed my problem right away on a Saturday. This is in contrast to another well known and highly rated company who I called first, but told me they would only come at a rate of $322/hour. And when I asked if they could schedule me an appointment for Monday, they told me I would have to call back on Monday. Not only Hugo they not charge me an exorbitant amount, Miguel the technician came within the hour, was friendly and got the job done! This will be my go to plumber from now on!! read more

If I could give more than 5 stars I would!!! Alfonso got the job done. After two weeks of a clogged sink, he came over and got the job done!!!! The manager answered within two seconds of the phone ringing, booked me for the next morning!! Awesome customer service, highly recommend this team! read more

Hugo, Thank you so much for your quick, after-hours response to help my elderly mother with the plumbing problem in her home. I was miles away when the problem happened, so it was a huge relief when I telephoned your company and was able to speak with YOU - rather than an answering machine! Furthermore, you more than exceeded my expectations when you made time *that* evening to go fix the problem. You, your company, and employees are all awesome, professional and dedicated! Your phone number is now stored in my contact list (speed dial, lol) and you'll always be the plumber professional that I call. Highly recommend! read more

Excellent Service! Noe and Hugo were professional & courteous. They explained the problem and the solution options clearly to my family- we definitely recommend this business! read more

I have called Hugo for several of jobs on different properties that I work on and he gets back to me right away.

He explains everything thoroughly which I can really appreciate and the best part about it is gaining the knowledge myself!!

Never thought I could love a plumbing company but here we are. We had a clogged drain the night before Thanksgiving and every Plummer was booked but miraculously Hugo was able to come by within a couple hours and he fixed a complicated issue like a pro! Just moved to the neighborhood and am so happy we found Diamond Plumbing. We will definitely be calling him again with any plumbing issues. Highly recommend this company! read more

I realize I never left a review for Hugo! So after the plumber (hurst ) our home warranty sent out to our house for a pipe clog royally screwed us over! I called Hugo (found here on yelp! ) and he was able to come out the same day and fix the issue correctly. All we needed was our drains snaked but he was so nice about it and super professional ! Thank you!!! read more

Great SERVICE easy to deal with fast response thank you for your help again . Nik read more

I meant to add this review weeks ago when they came to fix a broken faucet but forgot and I suddenly remembered! I called them about an outdoor faucet that broke and water was spewing out all over. The only way to shut it off was to turn off the main water. This happened around 5 pm and they came immediately. The guy who came out worked tirelessly to fix it, as he came across multiple problems that only exasperated the issue (our house has many unusual issues like this, unfortunately). They gave us a good deal and did truly honest, hard work. He was so kind and also walked us through the whole process so we could understand the issue better. I've hired them before and will do so again. Every single time they have been amazing. Thank you guys!!! read more

The office building I manage had a clog in the sewer line and our parking lot was a mess . . . literally! Hugo was available and came over immediately. He determined the problem, which involved cutting into the asphalt to replace a junction in the pipe. He called a company he knows that works with the asphalt and went above and beyond to see that the pipe was repaired. I'll be using Hugo for my plumbing problems in the future! read more
