In 1910, Dimond Plumbing & Heating Co. began its journey as many families and businesses sought new beginnings in the East Bay post-1906 earthquake.
Our roots are in Oakland's ""Dimond District,"" where we were situated at the corner of MacArthur Blvd. and Coolidge Ave. for many years.
In the early 1900s, we completed extensive plumbing work for both the Alameda County Building and the University of California - Berkeley.
While working on commercial and industrial projects, we established a strong reputation for quality and trustworthiness within the Oakland community and the East Bay region.
A significant portion of our clientele today consists of the children and grandchildren of our first customers.
My plumbing career began at 17 when I was digging ditches.
As I progressed in the plumbing industry, I realized that no matter how much I learn, there is always more to discover.
With ongoing code updates, technological innovations, and the multitude of product options, it’s evident that complete knowledge is unattainable.
My primary offering to customers is a dedication to providing excellent service at a fair price.
That’s the same standard I encourage my son to uphold.

Recommended Customer Reviews

I've had Mike over twice, the first time to install a sink disposal unit and later for a badly clogged kitchen drain. He is very responsive and reasonably priced. The man knows his stuff and is generous with his explanations which I appreciate. Nobody likes having plumbing work done but it's nice to learn a little when you're paying for work.
Oh, and I even got a thank you note in the mail! That's class.

Mike is the owner and operator of a world-class plumbing company. The level of service and competence you get from Dimond Plumbing and Heating is 5/5 stars. Please reach out to Mike for anything plumbing related.

Mike came one day to give a quote. He was very honest and even laid out some options for us. We ended up going with Mike to fix our flange. We scheduled an appointment for one day, and Mike called back and said he could do the next day. Sweet! Mike did a great job. We appreciate his work and honesty. Definitely will use Diamond for any other issues that arise in the future.

Our experience with Mike at Dimond Plumbing was excellent. He was straight forward in his appraisal on fixing the reduced flow of hot water to our kitchen sink. His first recommendation was at a lower cost and was based on his experience on how this problem could be approached.
My experience has typically had contractors/repair personnel take the more aggressive/expensive approach. In this case Mike was fair in his recommendation and provided a fix that works.
I would highly recommend him for your plumbing needs.

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.

Outstanding workmanship & professionalism. Mike is extremely knowledgeable, efficient, very polite & nice. Cleaned up after work was done. Highly recommended! --Sandy

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

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.

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

Mike is a straight shooter! He treats you like he'd treat a friend - doesn't do work he doesn't need to do or that is out of his scope. He was good about communicating and was friendly in person when he was doing the work. He's good about explaining the ""why"" behind why he needs to do something which really helps you understand the needed work. I would definitely bring him out again if we need it!
