I cannot say enough good things about our experience with GEM Electric!
We had an electrical issue and had initially contacted another contractor. After assessing the situation, they told us the work was going to be much more complicated than they originally thought and that it would take several days to complete. Before moving forward, I decided to get a second opinion and I am SO glad I contacted GEM Electric.
From the moment I reached out, their response was immediate. They were quick to respond by phone and just as quick to come out and assess the problem in person. They were professional, knowledgeable, and straightforward about what actually needed to be done. I was provided with a detailed estimate almost immediately.
Excellent service from start to finish from Gem Electric. They’re professional, punctual, knowledgeable, and took the time to explain everything clearly. The work was done efficiently and neatly, I’m very happy with the results and would definitely recommend them!

We had a great experience with Gem Electric. Their team was professional, efficient, and completed the work with excellent attention to detail. A special thank you to Luis, who was incredibly helpful throughout the entire process. He took the time to answer our questions, kept us informed, and made everything smooth and stress-free. We highly recommend Gem Electric for anyone looking for reliable and high-quality electrical services.

Luis is professional, straightforward, and easy to work with. Very few electricians hold the certifications required to do electrical work in my building, so you know Luis and his team are definitely very qualified. He quoted me a great price and got his guys out to DTLA quickly to install an outlet.
The exact outlet frame I have throughout my home was out of stock and had to be ordered. Instead of waiting for delivery to begin the work, his electricians installed a temporary cover and came back to swap it for the correct part once it arrived. The finished work looks great.
Thanks a lot, guys 👍🏻
Very professional from start to finish. Great communication and helpful even after the work was completed. I had some questions about electrical I was doing myself and Luis answered all my questions and gave me advice. Would highly recommend!
Great team that consistently delivers on both small and large projects. Their work is reliable, efficient, and always meets expectations. Luis is amazing to work with, responsive, professional, and goes above and beyond to get things done right. I’ve never been disappointed with their service or results.
Had Gem Electric handle a full lighting refresh across my unit: bulbs replaced and fixtures addressed throughout. Luis came by personally to take care of everything, which already sets the tone for how seriously they take their work. He was punctual, worked cleanly, and went through the unit systematically to make sure every fixture was properly sorted before leaving. …

He was punctual, worked cleanly, and went through the unit systematically to make sure every fixture was properly sorted before leaving. No callbacks needed, no loose ends. That kind of owner-level attention is rare and genuinely appreciated.
Highly recommend for any residential electrical work.

Working with Gem Electric was the best decision we made during our renovation. What sets them apart isn’t just their sophisticated technical knowledge, it is also their perspective. They approached the project holistically, looking beyond immediate fixes to how a space will actually live and evolve. During our renovation, they surfaced layout refinements, electrical safety protections, and lighting solutions that we hadn't even thought about - all of which were thoughtful, forward-looking improvements that really elevated the entire outcome.
And the execution matched the vision: Their work is precise, clean, and disciplined. All communication was direct, professional, and timely.
Thank you to Gem Electric for your incredible services and I can't wait to work together again.
We used Gem Electric to update our electric panel. Luis corrected issues from prior fixes and worked late to minimize our disruptions. He demonstrated excellent job knowledge and work ethics. We will trust him with future electrical work and pricing.
Luis is a very good electrician; his customer service and workmanship are exceptional.
Luis and the good folks at Gem Electric installed a new panel at my residence. They were on-time, highly communicative, reasonably priced, fast, and did an excellent job. You can’t go wrong hiring these guys for your electrical needs!

Highly recommend Gem Electric. They are very friendly, professional, and respond quickly. They do the job right and do not cut corners. I needed a pendant light installed above my sink, under cabinet lighting added, and my dining room light moved about five feet. They also fixed a broken outlet used for my washer and dryer, which was a lifesaver. Everything was done flawlessly and quickly, and they made sure all the electrical work was working perfectly before leaving. Great quality work, reliable, and easy to work with. I would absolutely use them again.
Awesome workmanship, excellent communication and would definitely recommend! Job is done fast and clean!

Hired Luis to install an EVSE charger and run new wire to my garage so that I could charge my EV. Luis and his crew worked quickly to rewire and mount the EVSE. The drywall cuts were so clean that my repair job to the wall was minimal. I was so impressed I hired them back to run three buried conduit lines and related mounts for a solar/battery installation a few months later. Luis provided clear estimates of the project and advice on how to save money with installation. He provided several competitive options. The work itself was completed quickly and as described. He went above and beyond communicating with me, including sending a sketch of how the conduit would run on the wall. Really appreciate his patience explaining code requirements and translating my solar contractor's requirements. We passed inspection with ease and I'll be contacting him for my future electrical needs. Choose Gem Electric, you won't be disappointed!

Luis showed up on time, worked efficiently, and left everything clean and tidy. It’s such a relief to find a professional you can truly trust in your home. I will absolutely be calling him again for future projects. Thank you, Luis, for the outstanding service!
Luis is extremely knowledgeable and very professional! He walked us through a variety of options and delivered on what we chose. He was flexible around our schedule restrictions and we couldn't be happier with how it turned out. Very dependable and we will definitely use GEM again in the future.
