"We needed our entire 1960s home rewired. JJC Electric replaced all the old cloth wiring with modern Romex, installed a new panel, and added GFCI outlets in every wet location. The inspectors were impressed with the quality of work."
"Jamie and his coworker were very skilled, efficient, and friendly. His company installed 5 lights, including a chandelier, and fixed a loose socket on a ceiling fan. Highly recommend."
