Reviews

Highly recommend - punctual, professional, and solved the main issue at hand which was installing an electric shut off switch. Would definitely higher again 👍🏽

This is a bolt, a nut, and a piece of padding under a clamp. This is not $350 worth of work. High end button photocells cost $40 at Lowes and Home Depot. I can see charging a small trip fee, and the cost of a "new" button photocell, and a fee to actually install.

I contacted 517 GMJ because I'm hosting a dinner tomorrow night and my chandelier started blinking intermittently. Gilberto made it out here last minute at 7:30 pm to fix my electrical issue so me and my guest dont have to deal with blinking overhead lights tomorrow during dinner. He showed up on time and did great work resolving my issue. If I have any electrical issues in the future 517 GMJ Electric is my go to.

The team did an excellent job mounting 3 sets of hexagon lights and adding a dimmer switch!

Gilberto with 517 GMJ Electric was excellent. He responded to my initial request quickly and came the same day. He was professional and committed to the job that required him being here until 9pm. I appreciated his dedication and his attention to detail cleaning up after himself. He even explained what I had going on inside my panel. I’m a REALTOR and very particular on who’d I recommend. I can say without hesitation that he will be on my referral list.

Gilberto was quick to respond to my request, visiting the next day for a walk through, and fitting in my job the next day. He took the time to understand the issues I had experienced with my electric panel and explain what he was doing, and what I could expect with replacement of my panel. During his walk through, he fixed a loose connection that addressed issues with my cooker. His team of two showed up promptly the next day to replace my electric panel and Gilberto called at the end of the day to confirm that all was in order. It was great to work with him and his team.

Excellent workmanship from start to finish. Gilberto, and Mario, I am truly grateful we met. I feel safe in my home after removing the rust with the old breakers and everything damaged by water intrusion. Highly recommend 517 GMJ Electric Inc!!!!
