How Long does a Whole House Rewire Take?

A full rewire for a typical single-family home generally takes between three and five working days. The project is usually completed in the following stages:

1. Rough-in Phase (1–2 days): Electricians open wall cavities and pull new cables throughout the home.
2. Rough-in Inspection (1 day): An inspection is typically conducted the day after the rough-in is complete, depending on the inspector’s availability.
3. Trim-out Phase (1–2 days): Local electricians install the new devices and fixtures.
4. Final Inspection: A concluding inspection is performed to verify the work meets safety codes.

Several factors can extend this timeline. If your home requires a 200 amp panel upgrade to handle modern electrical loads, this typically adds another one to two days to the project. Other variables that influence the duration include the total square footage of the house, the ease of accessibility (such as having an unfinished attic or basement), and the age of the existing system, particularly if outdated knob-and-tube wiring must be removed.
