Sometimes your electrical switches just wear out. Some of you may be wanting to upgrade to paddle, slide, dial, touch, dimmer, or Smart type switches. Some houses are just not wired with a neutral or ground wire. You may still be able to ground your switches if the metal boxes in your walls are grounded.
If so, our electricians will be able to ground some switches directly to the box. Metal boxes are grounded from the EMT that is run back to a grounded electrical panel. We can rewire your houses with a ground wire, but this is typically an expensive endeavor.
