National Baseline & Scope Drivers
Replacing obsolete or hazardous wiring throughout a home — knob-and-tube, aluminum branch, or ungrounded systems. National planning range for this job sits between $8,000 and $30,000.
Key Price Drivers for Whole-House Rewiring
- Existing wiring type: Knob-and-tube requires full access and is the most labor-intensive. Aluminum branch wiring may be remediated with COPALUM connectors at receptacles rather than full replacement. Ungrounded 2-wire systems often need new cables pulled to every outlet.
- Access — finished versus gutted: Rewiring through finished walls with minimal drywall damage costs more per foot than rewiring during a renovation when walls are open. Fish-wiring and strategic access holes add labor.
- Panel and service condition: A rewire almost always includes a new panel. If the service entrance is undersized or the meter base is obsolete, a service upgrade runs concurrently.
- Code upgrades triggered: A rewire brings every circuit to current code: AFCI protection in bedrooms and living areas, GFCI in kitchens and baths, tamper-resistant receptacles, and smoke/CO detector interconnection.
- Home size and circuit count: A 1,200 square foot post-war home may need 16 to 20 circuits. A 3,000 square foot modern home may need 40 or more. Each circuit is a home run to the panel.
