Recommended Customer Reviews

I needed a couple of external power extensions for a hot tub and for a power outlet by our gate.
Very easy to work with. Got the jobs done quickly and perfectly. Thanks!

Randy did a great job handing the whole process from the beginning. He was able to find the most efficient solution to our project and accommodated to our work schedules. We're very happy with the results.

We purchased a home here in Castro Valley in 2014 and picked Randy because of his great reviews on Yelp!
He is FABULOUS! He changed out our original electrical that was put in, in 1950!
He gave us electrical access in the back yard to accommodate us for our new hot tub and BBQ area!
He was respectful, knowledgeable, always prompt and his prices are reasonable.
Everything is working great and we will always call him first when an electrician is needed!
Call Randy! You will be glad that you did!
Thank you Randy!

Summary: Randy and his team were punctual, thorough, detail-oriented and got the job done at a very reasonable price.
Randy was one of the first electricians I contacted last year to install recessed lighting in our living room. Thank you Yelp for helping me find someone local! I was impressed with all of the excellent reviews. The first time I called Randy I had NO idea what would be involved in this project. Randy explained what would work best for him: I buy the lights, and he can come install everything in one day. But I had no idea what to buy. Randy also helped walk me through this info. I got a few more estimates and finally decided to go with Mopia Electric based on their excellent reviews and very fair price.
After setting a time and date with Randy, we finally got our lights installed! Randy and his assistant were punctual and thorough in scoping out the project before they got started. Randy was clear about what he would and wouldn't do: install lights and dimmer switch - yes; patch up wall - yes; repaint patched wall - no. Before I left, I saw them laying down drop cloths over our furniture and floors, which was super thoughtful! I had another team in the house installing floors and seeing Randy's attention to detail made me feel sad that the flooring installers had left sawdust on every solid surface in the home without any warning. :( Randy called my husband mid-project when they realized that support beams were blocking the original light locations we had discussed. Appreciated that he called to get confirmation and explained the situation before going ahead with it. Came home to bright, evenly spaced lights controlled by a dimmer switch. Wonderful experience working with Randy and would definitely call them again for other electric projects in the future!

Randy is great! We lost power to all of our bathroom outlets and Randy came over, troubleshooted the problem, made multiple trips when required, explained everything that he was doing, and answered text messages quickly and outside of normal hours.
Can't say enough good things about his work!

If you are looking for very skilled, highly competent, completely reliable and fair market pricing for quality work, then look no farther as Randy and Mopia Electric are all that and more. We had some electrical work done on our house by Mopia: Installing new lighting up our front walk that included adding an additional fixture in a tricky spot that Randy quickly and easily troubleshooted, then accomplished. He also installed a new outdoor flood light as well as upgraded and repaired some internal outlets too. We are going to need some additional electrical work done soon, so you can bet Mopia Electric will be our FIRST call for a quote. Thank YOU Randy and Mopia Electric!

5 stars. On time, communicates well, got the job done. I can't add much to the many favorable reviews already here so I will just say don't hesitate to call or text Randy for you electrician needs.

Randy is just one big wad of awesome. Works quickly, cleans everything up so it's better than when he arrived, doesn't scoff at how hubby screwed up the wiring on a DIY binge. Expert electrician, reasonably priced, quick response. He stuck his hand up in the ceiling and a rat ran across his hand, and yet he came back after we got rid of the rat and finished the job. Highly recommend.

Randy and his team were on time and meant business! The scope of my job kept changing (because we kept changing what we wanted), but Randy took it all in his stride and worked to give us the best deal he could.
Randy really knows his stuff (the pg&e fellow complimented his work), and I'm sure we'll work with him on the next stage of our home renovation. Thanks Randy!

Mopia Electric installed our Electric Vehicle fast charger. We are Super impressed with their service. Friendly, on time and trustworthy! Highly recommended!
