"Jamie and Lilly did an amazing job installing our pendant light, relocating our carbon monoxide device into the hall and some patch work. Bonus: it was all done in the same visit. Highly recommend JJC Electric."
"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."
"Had security cameras hardwired around our property. JJC Electric ran all the cables through the attic and walls so nothing is visible outside. Four cameras, one NVR, everything works perfectly on the app. Very satisfied."
