About this service
An insulator is a material, such as rubber or plastic, that prevents electricity from flowing where it shouldn't. It is wrapped around wires to keep power contained and protect people from accidental contact. If you notice exposed metal on your cords or wiring, the insulating layer has been compromised. This is a serious fire and shock hazard that requires immediate attention to prevent short circuits or injuries.

When would I need an electrical box extender?
An electrical box extender is used when installing new wall coverings, such as thicker drywall, over an existing electrical box. It brings the box's opening forward to align with the new surface. This ensures that switches and outlets can be mounted securely and flush with the wall. It's a practical solution for a clean finish in Berkeley homes.
