Reached out to Michael for a quote on help installing a problematic valve on our bidet. He was transparent with the cost and was able to stop by the same day. He drove over and fixed it right away. Great guy, top notch service. Highly recommend. read more

Have been dealing with slow running pipes in upstairs shower and tub ever since the 90s. Consider myself somewhat handy, so devised my own methods to deal with it and the old piping over the years, putting off that the piping probably needs to be changed out. Well last week, my "maintenance" remedies no longer worked, and my shower in one room and tub in the other room, would not drain at all. So, after messing with it for years, I decided to call in the pros. I wanted to keep my money in the local economy, so called Dimond Plumbing and Heating. Got a call back from Michael, who explained he was booked for now, but with the info I left him on the phone, he began to chat with me and ask questions about my situation. He ended up giving me his years of experience on my issue, as well tips from being familiar with the houses in the area. After about a 20 minute phone call, he left me with what his best recommendation was to fix my problem! I was blown away! He could not take the job, but basically did, as he told me what he thought needed to be done! What extraordinary customer service! Now here is the kicker: 2 days later, he called me back and left a voicemail asking if I had done what we discussed, and if it worked! Wow! You just don't see that type of service anymore. Since his recommendation DID work, I am sorry that the only "payment" he gets from helping me is this rating, but believe me.......if I have any future plumbing or heating issues that I can't tackle, you know who I will be calling! Thanks Michael! You are a class act! read more

Michael stands by his work! He came out a few times for a kitchen sink leak and to install an earthquake gas shutoff valve. His prices are reasonable, and he came back for free to double-check our sink. He's great! read more

Mike saved me from having to buy a new toilet! Another company had said the physical object in the toilet was irretrievable, and that we'd need to replace it. I called Mike, and before he would even give me a quote on toilet replacement, he said he'd try and come over and get the object out. He came the same day and got it out in, and this is not an exaggeration, 20 seconds. Also, we talked about Schrodinger's cat and he told me a good plumber. Mike is a grade A plumber who also tells jokes and quotes philosophy. There's literally nothing more I could ask for. read more

I originally called Bustos. They came right out and gave me a quote for a new water heater. When I called a few days later to get the job done I found out they were on vacation for several weeks. I called Dimond and sure am glad I did. Michael came right out and told me there was a loose fitting, which he tightened. I couldn't be more pleased with his service. I know who I'll call when I need a new water heater. read more

Top line: WOW! Our guest toilet sprung a leak in the water supply pipe at about 9:30pm on Sunday, which meant we had to turn off the main water supply to our home. Needless to say, we needed someone fast! We left a message for Dimond and were called back early the next morning by Mike, who was ready to come out and address the problem. That prompt response alone was pretty amazing, but here is where Dimond really shined... My husband provides expert testimony and had to be in court on Monday, and I am conducting field work 60 miles away from our house each day - so neither of us could be home to meet Mike. We made arrangements to leave the keys under the door, and also let Mike know that we had a very large, but friendly dog who would be greeting him when he arrived. Mike was totally cool with all of that, arrived after both of us had left, and had everything fixed (including a small fix to our master bathroom toilet that we requested at the last minute) by the time we arrived home from work. He called my husband and gave a detailed account of everything he'd done, and we were able to pay him by credit card over the phone. (A very fair price too.) Although we never actually met him in person, every interaction we had with him exemplified customer service!!! I would use Dimond again in a heart beat - thank you for your great work!! read more

Mike talked to me on the phone twice, giving me advice for no charge. He was very helpful and friendly

Michael is the best. He gets the job done right quick. I would recommend him to anyone who needs plumbing works. A very happy customer.

Dimond Plumbing and Heating came our rescue when a serious drain issue erupted just hours before our Golden Anniversary party. A potential disaster was averted when their skill and determination was brought to bear on a complex problem that had both build-up and structural elements. They came with a "whatever it takes to do the job " attitude, had a surprisingly affordable fee, and were very nice guys. Steve Wade Alameda read more

Mike is wonderful to work with. He truly cares about his customer and making sure they get the service they desire. Just a great person! read more

So glad I have someone I can call for future plumbing service! I had a slight, slow water heater leak and Mike came by to assess the problem, he made a small change and fixed the leak at no charge. Because of the age of the water heater I wanted to change it out to avoid a future catastrophe. Mike installed a new water heater, excellent product with excellent warranty at a totally reasonable price. He also installed a new kitchen faucet and fixed that leak as well. If you want great service, excellent American made product (water heater) and a fair price call Dimond Plumbing! read more

Just had Mike come in and troubleshoot the wall furnace in our house. Very professional and did the job as quoted also gave some advice on the malfunctioning floor furnace in our 1940s house. Will use again in the future. read more

Had a backed up kitchen sink ongoing problem. Kept trying the chemicals to try to dissolve the clog. Even snaked as much as I could from the flush out. Got a bunch out, but still no dice. Mike came out promptly at the appointment time, muscled the clog out (it was really far back and tough) for cheaper than other called companies, and gave me a discount as a first-timer. He was friendly, chatted it up and answered my questions, and even gave me a friend's card for an electrician quote. Good guy, good company so far. Gonna check them out again for a more serious job. read more

Dimond has done several jobs for us and we've always been very happy with the results. They installed new toilets, the put in a new bathroom vanity with sink and back splash, and recently they replaced our ancient wall heater with a new one. Response time is prompt and the work is top quality. We won't use anyone else for our plumbing and heating needs. read more

I found DImond Plumbing through Yelp. My preference is to use personal referrals, and Yelp is as close as it gets to that. I just moved to San Leandro, and had Michael install a whole-house water filtration and softener system and a dishwasher. Michael provided a fixed quote for both, and despite unforeseen challenges on both fronts, honored that quote. I had lots of opportunity to speak with Michael about ethics, reviews, and fixed-price versus time and materials approaches. The great thing about that is that I can also say that I'm impressed by Michael's total honesty, as well as his belief in the system of authentic customer reviews and customer satisfaction. They don't come any better than this. read more

Mike is wonderful! He's honest, has fair prices, and is a great guy!!! We called several plumbers when our water heater broke and Mike gave us the fairest price, explained why he was using the brand that he used, and why the heater he chose was the right one for us. My husband and I both liked him and felt that he was the best choice by far. We will never use anyone else! read more

MIke and co. are pros, and they're just wonderful guys. They take the time to explain what the problem is - and there's always a problem in our 80 year old house - and then they FIX IT, right away, with no excuses or delays. Oh, and it stays fixed. read more

I got a few quotes because I had a minor gas leak. So I called Mike and I told him where the leak was so he sent out Sean. Sean came through and was nice enough to go under the house and evaluate things. So Sean confirmed that the gas leak was where I said it was. Unfortunately the crawl space was too small for him to fix, so he recommended someone else that he knew and trusted. They(Dimond) have great service and they didn't even charge us for assessing our problem. They run a very honest company and are good at what they do. Thanks guys! read more

These guys are just terrific. They came out to my house several times last year because we were having a stubborn sewer problem. Prompt, efficient, hardworking and pleasant every time. They even cut us a deal since the problem was recurring (not their fault). Six months later, one of the pipes they replaced under our sink started leaking. They came out the next day after we called and replaced it for free. Great service, great attitude, great guys! read more

Called Dimond Plumbing at 10:00 am when another plumber cancelled unexpectedly...had two issues in two separate units of a fourplex and both were fixed before 12:00....awesome service...will definitely use again. read more

What a great experience! Mike returned my request for a quote within a few hours. Unlike other vendors who needed to send someone out for an estimate (for a fee), Mike gave me a price range for replacing my leaky sink pipes with new, metal ones over email. This gave me confidence that the range would be something manageable and I wasn't getting over-quoted. Mike came by on time, was nice to our dog and baby daughter got the job done for the lower end of his estimate and even re-worked the dishwasher hook up at no additional cost. Great experience and I'll be calling Dimond in the future. Thanks Mike! read more

I had an exceptional experience with Dimond Plumbing. The positive interaction began on the telephone. Mr. Patrick listened carefully to the work I needed performed. He thanked me for my call and said he wanted to earn my trust. Many contractors behave as if they are doing me a favor when I contact them. His attitude was refreshing. I was impressed by his professionalism. I also wanted to commend Dimond's lumber for his work ethic, knowledge, and humor. He was punctual. He took time to explain the problems and solutions encountered on this job. One task I needed performed was a gas line test. This grew into a major problem as a former contractor had cut halfway through the diameter of the gas line. It was a very dangerous situation. Dimond was very accommodating in scheduling our one day project as it grew to three. I appreciated this very much. Dimond has indeed earned my trust. I recommend Dimond Plumbing to everybody I know. read more

Honest, trustworthy, honorable, friendly. I highly recommend this plumbing company to all my neighbors. Mike came out on a Friday late afternoon before a long weekend when my daughter put a LOT of toilet paper down the toilet. He quickly fixed the problem, charged a reasonable price and was on his way. I was so grateful that he was able to come out so we weren't stuck with a plugged up toilet for a whole weekend. On top of excellent service, he sent a thank you note! I should have sent him one! Out next experience with him and his crew was equally as easy and satisfying. read more

Mike's crew put a water heater in our house a while back and did an awesome job! They even let my kids help drill holes for the drain tube. Recently I had a problem re-lighting the pilot. I called Mike and got a voice mail saying he was away on personal business and wouldn't be returning calls. I left a message anyway and within 15 minutes he called me back and walked me through the re-light procedure. I am so impressed that he took time out of his personal vacation time to reach out and help me. Thanks Mike for keeping us from cold showers. Awesome service! read more

I didn't even use Mike's services and I can still say he is the best! I left a message about a gas fireplace we are having continued problems with. He called me back within an hour, and said he might not be able to work on the problem.. but he was able to give me some more information about what might be happening with it, and spent some time giving me a referral to someone who can probably fix it. It's been a continuing problem, and it was great that someone finally took the time to try to help and explain what was going on. He knew he wasn't going to make any money helping me over the phone - he was just being a genuine person with an expertise to share. When your reputation preceeds you, it's important to maintain it. When I need HVAC repair I'm calling Mike. read more

These guys never pick up the phone. It goes to the same cell voicemail. Takes them forever to get back to you if they get back at all. You end up playing phone tag....called last Thursday and they scheduled an appointment for today between 9-11A.M.(Wednesday). Never came or called. I called early afternoon and left a message and no one ever called back. I don't know how you stay in business with this kind of customer service. Called another company, they answered right away, came after 5P.M. as I requested, and installed our new faucet in an hour. read more

We have now had two experiences with Dimond Plumbing and in both cases we have been very pleased with the results. Dimond replaced two fixtures in our remodeled bathroom and saved us considerable grief, expense, time and money. They pointed out the the fixture we purchased for the shower was a different brand than the one originally installed and that the fittings did not match. They could have just gone in and tore apart our walls and charged us for all the labor to do so BUT, instead they explained that if we had them obtain the same brand as we had (new, of course) they would go get the parts, charge us a minimum markup and install the new parts, as agreed. Wow! I was very impressed and amazed. They actually restored my faith in (some types of) trades people and got a customer for life all in the same job! The other project Dimond just did for us, is something we wanted to do ever since we bought our home and that is the installation of an Earthquake Gas Shut-off Valve. With all the seismic activity we have had recently in our area, the installation was greatly appreciated and apparently it may give us a break on our home owners insurance! Very easy to recommend Dimond Plumbing. Thanks guys! read more

I didn't had a chance to use Diamond Plumbing because due to an emergency, I had to go with another Plumbing company that was able to come out sooner. However, I am giving Diamond Plumbing and Heating Company 5 stars just for interaction and customer service. Mike was extremely friendly and personable returning my call with a very nice voicemail even though I said I had to go with another company due to timing. He was extremely gracious, friendly and personable. I am sure if I were able to use Diamond Plumping if customer service was of any indications these guys would have been awesome! read more

I did not actually use Dimond Plumbing but I felt the need to leave a review based on Mike's great customer service. I called and left a voicemail and got a call back within only a few hours of my somewhat emergency situation. (Other companies are taking days to call back during this winter and holiday season). Mike explained to me he wasn't the right person for the service we were looking for and why ....and he was very kind, and genuine. I asked him if he could call my mom and explain (since it was her home with the issue) and he did that even though he knew he couldn't do the work so there was no sale in it for him. She also commented what a really NICE person he was. He also helped us understand the situation. I can see why his ratings are 5 star. read more

No longer in business. I called for a week, no answer, no returned call. voice mail full.

We had a slight gas leak in the attic so I called around to get different estimates. These guys came by the house and quoted me significantly less than what the other plumbers did. I also didn't get the "shady" vibe from Dimond that the other plumbers had. Kit came by and did a great job fixing the problem. I am so glad to have found Dimond Plumbing and I highly recommend them! read more

Mike is awesome. i called on Monday with a clogged kitchen sink. He couldn't make it Monday but said he could the next day, Tuesday, between 12 and 2. He showed up at 12 and it took only 10 minutes for him to clear my drain. He also pointed out a potential problem if I was not careful in the future with the drain. I tried and tried to clear it myself, but obviously did not know what i was doing. Mike discounted his fee, which I appreciated. I strongly recommend using him and plan to call him if I need any plumbing help. read more

What kind I say.....this company is awesome!!! I would give them 10 starts if I could. Used them in the past for a minor plumbing problem. Then had them back months later to replace my water heater before it died since it was old. Just had them back (was so happy to know they were still in business) to take care of my kitchen and bathroom facets. They are honest, reliable and have excellent customer service and work ethics. You won't be disappointed. Thank you Michael & Shaun! read more

Had a problem with wall furnace. Called Michael , he fixed the problem without delay. He is friendly,efficient and his prices are reasonable. Definitely would use again. Dimond heating and plumbing will be my go to plumber from now on! read more

My husband and I were very pleased with Dimond Plumbing's recommendations, and expect we'll be using them in the future. We had been considering what would have turned out to be an expensive upgrade, and Mike suggested a more cost effective long-term approach. Prompt, personable, and the kind of advice you know is given as if to a friend, rather than to make a buck. read more

Long overdue, but Mike at Dimond plumbing rocks. The water pressure in my house was too high and the water heater busted :( My house was under warranty, so my insurance paid for the water heater replacement. I was told I needed to install a water regulator to prevent this from happening again...of course, not covered by the insurance. The plumber the insurance sent offered to install one for $400. Seemed steep, so I checked yelp and got a few quotes. Mike at Dimond quoted me over the phone, it was the best price and he sent someone out the same day. I was able to pay over the phone with a credit card. Everything went great. Got home from work that night and everything was all taken care off. Easy peesy :) ***Now, almost a year later, the water pressure seems to have dropped. I called Mike to ask how to increase the pressure. He offered to swing by and do it for me! This guy is awesome. He's officially my plumber. Don't hesitate calling this guy. Good prices, super reliable, great service, and good reviews, what more could you ask for?? read more

Kit from Dimond just left. I had new granite coutertop installed last week and needed the new sink, faucet, garbage disposal, water filter and dishwasher hooked up. Did all within 90 minutes! FABULOUS, friendly and clean! Price was right too! Thanks to owner Michael Patrick for sending out such a qualified guy so quickly! Highly recommend for any plumbing needs. read more

We recently had Michael from Dimond Plumbing complete some work and were very pleased with the entire experience. They responded immediately to our emergency phone call, did the work efficiently and professionally, and were friendly from beginning to end. We really felt well taken care of and know that the job was done right. We have been using Dimond plumbing for many years and they continue to be great - excellent work with reasonable prices and consistent high quality! read more

What more can I say about Michael and his crew Kit? I spent about 3 months planning on a backyard renovation which included adding a gas line to my fireplace so why not add 2 additional connections for a BBQ and fire pit. Kit came on scene and provided a honest quote for approximately 1 day of work. I accepted and the job was completed professionally and quickly. There was just 1 minor glitch but Michael made sure it was taken cared of within 24hrs. So far this has been the simplest part of the renovation. When I finally decide on adding the fireplace insert and fire pit I know who to call. Thanks Michael and Kit for the clean and professional job you did. I wish more contractors would be as concerned as Michael about pleasing their customers. read more

Excellent service! Reliable and honest. Have used them for both heating and plumbing repairs. Won't go anywhere else.
