 How can we make you smile? Today, S&M Electric sheds some light on when your home or business should have an inspection by a qualified electrician. If your lights flicker like a bad horror movie when you flip the switch or plug something in, it's time to call S&M Electric. If your plugs and switches are taking a vacation, but you're still home, it's time to call S&M Electric. There goes that GFCI again.
