About this service

An extender is a simple component used when an electrical box is set too deep behind a wall surface, usually after new tile, drywall, or paneling is installed. It brings the box flush with the wall so your outlet or switch can be mounted securely and safely. This is necessary to meet fire codes and ensure your cover plates fit correctly. The cost of materials and labor typically varies. Exact pricing confirmed free on the call.
