Recommended Customer Reviews

Unexpectedly lost power to part of our upstairs area with lights dimming and outlets not working. Contacted Mark and he came out the next business day. Within a couple of hours, he identified and fixed the issue. Reasonable price, great communication, and excellent service. Definitely recommend and will refer him to my real estate clients.

Mark helped us redesign the recessed lighting in the family room and kitchen as well as hanging lights in the kitchen and installing new sophisticated switches. He did an amazing job and was wonderful to work with. He was on time, neat, precise and efficient. I have used several electricians before and Mark was by far the BEST!!!

Mark made many great suggestions for our room addition that we hadn't even considered!!! Plus he upgraded our entire home...no more blown out circuits! Mark is reliable and dependable, plus he's a really nice guy! We highly recommend him!

Excellent work, friendly person. We were extremely pleased and would recommend Mark to our friends. Thanks again.

So happy to have a contractor do the job when they said they would, finish on time and within budget. Excellent experience. We added some additional lighting, ceiling fans and 2 new outlets. He was on time, very clean making sure to cover our furniture and floors and was very quiet. We are so happy with the results and the additional lighting is great. Highly recommend.

Nothing speaks more about a good service experience than repeat business. In late 2017 Mark added a 100 Amp subpanel to my detached garage and wired in 110V and 220V outlets on all the walls. He also wired in three lighting fixtures on the exterior. We couldn't have been more pleased with his work.
Yesterday Mark completed another job for us. Over the last year we did a complete backyard redesign that involved installation of a spa running 220V from a new subpanel, wiring and outlets for an outdoor kitchen, low voltage lighting for the kitchen, and installation of switched and unswitched 110V outlets around the entire yard perimeter. It was a long project and he was willing to work with us through the summer and winter coordinating his work with our schedules and the schedules of other contractors. Easy to work with, professional, absolutely trustworthy and his workmanship is amazing. We couldn't be more pleased.
Thank you, Mark, for another job well done.

Since referred to Mark's Electrical Services by a friend, we will never use any other electrical services professional. Mark is extremely thorough and conscientious, whether the job is complex or a simple bulb adjustment. He completed beautiful landscape lighting for us, and made much needed lighting adjustments to our interior. The added ""plus"" is that he never leaves a speck of debris or dust at the end of a job. Thank you, Mark, for your gracious and professional services!

Mark is awesome. We've used him for various electrical projects including outlet/switch rewiring, recessed lighting installation, electrical panel replacement, and at least 5 other projects for our house. He's incredibly efficient at making complex electrical changes, does everything to the highest standards, and is great at helping provide options to keep costs down. He's also great at understanding and setting up ""smart"" electrical devices and Wi-Fi-enabled lighting. Best of all, Mark is always on schedule, is super nice, and is easy to work with. I would (and have!) recommended Mark to anyone looking for a great electrician at a reasonable price.

Mark of Mark's Electrical Services is by far one of the best electrical contractors I have had the pleasure of working with. I am selling a home in Livermore, CA and needed a GFI outlet installed ASAP and was required to have a State, as well as City, licensed contractor do the work. I was extremely lucky to find Mark online. He went above and beyond for me, first by returning my desperate call, after business hours. Then he not only scheduled me for that same week, he even had an opening in his schedule and came 2 days early! He provided me with the most impressive Customer Service I have experienced in a long time. I had also just replaced all of our outlet and switch covers and he went out of his way to ensure the new GFI outlet matched. I will be sure to use Mark's Electrical Services in the future and refer him to everyone that I know. He is competitively priced and you are sure to have as wonderful of an experience as I did. Highly recommended!

Mark has done an amazing job! He helped us put in 8 can lights and three ceiling fans. New wires needed to be ran and new with the new lights and fans came the new switches. He worked hard to keep the house clean while installing, measured, and then measured again before making the permanent hole for the fixture, he was extremely friendly and very professional. Thank you so much for your work and I'd be happy to call you again for our next big project!
