Sometimes your electrical outlets and GFCI’s just wear out. Some of you may be wanting to upgrade from 2 prong outlets to 3 prong outlets. Some houses are just not wired with a ground wire. You may still be able to ground your outlets if the metal boxes in your walls are grounded.
If so, our electricians will be able to ground some outlets 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.
