Had our main panel go out after a recent storm, had bids up to 10k, Zach got me taken care of for a fraction of that, and took care of the entire process.
ZG Electrical upgraded our electrical panel to 200 amps, and Zack and his assistant did an excellent job. They took care of everything, including permits, making the whole process smooth and stress-free.
Zack and his team did an amazing job installing power for our new sauna, tesla charger, and an outdoor outlet. They ran about 100 feet of underground trench and made sure everything was done neatly and safely.
I had a very pleasant experience with ZG Electrical, from start to finish. I needed a main panel upgrade along with multiple other things. What mostly stood out was his outstanding professional demeanor. Cant recommend them enough!
Very satisfied with how Zach communicated and executed some electrical issues. I hired Zach to do an electrical inspection on a home i was purchasing and he was able to diagnose and repair loose wire, updated outlets, and wired in a tesla charger.
Zack had installed a 240V outlet for my EV charger. Smooth process from start to finish. I will be starting my whole home lighting upgrade soon and will definitely be working with ZG Electrical on that, big thumbs up.
Zack with ZG Electrical did an awesome job getting multiple 220v electrical lines ran for us to get our sauna and jacuzzi set up. The pricing was reasonable and the work was done very quickly!
Zak is doing the electrical for our master bath and master closet remodel. He has tremendous work ethic and is extremely professional. His work passed county inspection with flying colors. If I can give him 10 stars, I will.
Zach has been amazing to work with! From the very beginning, he has been on time and punctual. His communication is excellent. He has been very clean and made sure never to leave a mess behind. I would 100% recommend ZG Electrical.
