"I had some work done to replace an outdoor BBQ and a wire was cut accidentally in an awkward position underneath the BBQ. This cut out power to other areas. JJC Electric came out quickly and resolved the issue. Very knowledgeable and fair pricing."
"Replaced an old light fixture with a ceiling fan in our master bedroom. JJC Electric reinforced the junction box, ran a new switch leg for the fan control, and had it done in about two hours. Looks great and works perfectly."
