The answer to 'how much does electrical wiring cost' is that the cost can vary widely depending on several factors. In general, the cost of electrical wiring for a home can range from a few hundred dollars for a small project to several thousand dollars for a full home rewiring. The main factors that affect the cost include the size of the home, the complexity of the wiring needed, the materials used, and the labor required.
For example, a simple project like adding an outlet or upgrading a light fixture may cost a few hundred dollars, while a full rewiring of an older home could cost $5,000 or more. The cost also depends on whether you hire a licensed electrician or attempt a DIY project, as professional labor is a significant part of the overall expense.
