Awesome!!! He can fix it all!




Review of Mike Diamond Plumbing, Inc.

Ricardo, the amazing Jack of all trades, came and took care of all these plumbing problems, our old house has been having, for years. We kept getting leaks and clogs. He figured out why! He diagnosed the house like a doctor does a patient, and then performed 3 major surgeries in 1 day! He fixed the water line out front, replaced the broken emergency shut off valve, and installed a pressure regulator, to bring down the water pressure, that’s been causing our leaks…it was way, way too high! He had to cut off all the old parts off and weld the new parts on. It’s now brand new & easy to use! He then did an overhaul in the kitchen, on all kinds of crazy connections under the kitchen sink, that were leaking, and had been mickey moused together. Now, it looks like a new car under there, all chrome and streamlined. The electrical outlet under the sink had also stopped working last week, before the leak, so we hadn’t been able to use the garbage disposal. I told him I needed to call an electrician next, but he said “I’m also an electrician so I’ll take care of that.” He did & I felt like I’d won the lottery! Lol. (He works on furnaces and all that heating stuff too!) He figured out that the dishwasher was hooked up wrong as well, likely the cause of many clogs, so he fixed that too. Next, he replaced the back water line, so more cutting and welding & voila, now we can use the backyard water hose again! Everything is perfect! He did an awesome job! He has a strong work ethic. He wanted to figure it out for us, so that it doesn’t keep happening. He was very professional, super friendly, respectful, and down to earth! We are having him come back again to look at the bedroom shower and a few other things that have been out of use for a while because of leaking. It’s great that my family has finally found someone that we can trust!


Great fast service would recommend again for future use

Alan was her a couple of weeks ago, and I thought we had the problem solved. Turns out we did not, but Alan cheerfully returned and fixed the problem without charge. Very impressed. He is truly an asset to your company.


Outstanding Service!




Review of Mike Diamond Plumbing, Inc.

The main plumbing task included investigation and corrective action for what turned out to be a sewage leak related to a second-floor toilet inside the house. The corrective action included removing and replacing both a clogged toilet-sewage line, and a shower-water drain line that was affected by sewage backup. An unrelated secondary plumbing task was to remove and replace a water heater that was still functioning well, but was way past its recommended life span. The lead plumber, Ricardo (aka Ace), was very professional, meticulous in his approach, always arrived on-time, and took immense pride in his work. His crew (sometimes Joey, and sometimes Joel) also reflected Ace's values. The overall plumbing effort was a complete success, culminating with a satisfactory inspection for the new water heater installation by the Redondo Beach Building and Safety department. In addition to expertly performing the two separate plumbing efforts, Ace coordinated very well with Mike Diamond field service personnel (Victor), and personnel from other contractors who were subsequently involved in the leak investigation and corrective action effort (which included Leak Detection, Asbestos and Lead Analysis, Demo, and Repair activities). Ace and his crew also answered all of my many questions along the way, and cleaned up the affected work-areas after every one of their visits. Based on the above information, the overall service provided by Ace and his crew was outstanding! I refrained from discussing the pricing aspect of the efforts, because I have no comparative pricing data for the tasks that were performed.


I want to say thank you for your hard work during the holidays trying to accommodate us ion every way
