How Long does a Whole House Rewiring Project Typically Take?

By /

The duration of a whole house rewiring project primarily depends on the square footage of the home and the complexity of the electrical system. According to industry benchmarks provided by High Voltage Electrical, the typical timelines are:

  • 1,500 sq ft home: 3–5 days.
  • 2,000 sq ft home: 4–7 days.
  • 2,500 sq ft or more: 1–2 weeks.

The project typically unfolds in four distinct phases:

  1. Initial Inspection (1 Day): Licensed electricians assess the existing system and map out new circuit paths.
  2. Rough-In Wiring (2–3 Days): This is the most intensive phase where old wiring is removed and new cables are pulled through walls, attics, and crawl spaces.
  3. Panel Upgrade (1 Day): If needed, a new electrical panel is installed to handle increased capacity.
  4. Final Trim-Out and Inspection (1–2 Days): New outlets, switches, and fixtures are installed, followed by a rigorous final inspection to ensure the work meets local electrical codes.

While some smaller projects may qualify for same-day service, a complete rewiring is generally a multi-day undertaking to ensure that Safety is the #1 priority.
