How Long does a Whole House Rewiring Project Typically Take?

By /

The timeline for a whole house rewiring project varies depending on the square footage of the home and the complexity of the electrical system. According to industry benchmarks provided by High Voltage Electrical, typical durations are as follows:

  • 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 generally unfolds in four distinct phases:

  1. Phase 1: Initial Inspection (1 Day): Licensed electricians assess the existing system and map out new circuit paths.
  2. Phase 2: Rough-In Wiring (2–3 Days): This is the most intensive phase, involving pulling new cables through walls, attics, and crawl spaces.
  3. Phase 3: Panel Upgrade (1 Day): If necessary, a new electrical panel is installed to handle increased power capacity.
  4. Phase 4: Final Trim-Out and Inspection (1–2 Days): Technicians install new outlets, switches, and fixtures, followed by a final rigorous inspection to ensure code compliance.

Factors such as accessibility (e.g., plaster walls or difficult crawl spaces) and the number of required circuits can also influence the total time needed.
