About this service
An extender is a plastic or metal sleeve used to bring an electrical box flush with the wall surface after adding materials like tile or paneling. You need one when the box is too deep behind the wall, which creates a fire hazard because the devices cannot be secured properly. It is a simple but vital fix for safety and code compliance. Costs are typically low, depending on the number of boxes. Exact pricing confirmed free on the call.
