"Hired HomePro Electric to install a transfer switch for a portable generator. Erik did a great job. Showed up on time. Did an excellent job and explained how to switch our electric panel from the grid to the generator really clearly. I will definitely hire him again for any future electrical work that I need."

"I would highly recommend Santella for residential electrical work. I requested quotes from multiple companies for a wide range of work, including bringing existing wiring to code, repairing issues, installing new outlets, junction boxes and external lighting and video. They were excellent with communication and follow-up, transparent in pricing and risks/assumptions, were available more quickly than others, and offered competitive pricing. On the job they were fast and efficient, professional, didn’t try to up sell, did high quality work, and cleaned up. I will be using them again for all future work."
