We had an exceptional experience working with James the owner, Gary and MarkGen Electric! We are experienced real estate professionals, and signed up with MarkGen when a prior, trusted electrical company came in wayyy too high on a bid for EV charger install, and a 4-bathroom complex renovation. James is extremely personable, knowledgeable, and fair. Communication is outstanding, and any challenges addressed quickly and respectfully. We look forward to working with them on much larger projects in the future!

James and John were simply amazing! I had at least 8 things that needed to be assessed. They not only assessed those problems and offered solutions, they also helped me to figure out what each breaker was serving, they offered information that helped me to prioritize what was most important. They were professional and well informed about so many issues while being friendly and interactive, offering choices they have made personally regarding electric and other home repairs. I would HIGHLY recommend using MarkGen Electric and have already hired them to complete one of my projects. I will continue to use their services with all future electical projects and repairs.

Great service. MarkGen was the contractor assigned to me through my home warranty company. On a Tuesday morning I submitted a request to have a broken bathroom exhaust fan replaced - not an urgent request. I was contacted by MarkGen within an hour and they scheduled an appt for 8am the next day. James and John showed up promptly at 8am, took care of business and cleaned up behind themselves. My experience with them was excellent. They are now my go-to electrical contractor and I will refer them to my real estate clients as well!

MarkGen Electric did an excellent job upgrading my electrical panel and installing an air compressor in my garage. The work was clean, well-organized, and clearly explained from start to finish. They handled the panel upgrade professionally and made sure everything was safe, code-compliant, and ready for future use. The compressor install was done right the first time, with attention to detail and proper setup. I highly recommend MarkGen Electric for anyone looking for reliable, high-quality electrical work.
