House Rewiring Cost Calculator: what to expect
Rewiring cost scales with home size, accessibility, and whether you're also upgrading the panel. Older homes with knob-and-tube or aluminum wiring cost more because of the care and code work involved.
Across the United States, a house rewiring cost averages $17,893 once mid-range materials, licensed labor, and standard permits are included. The figures below are a national baseline; pick your state or city to apply local labor rates, material delivery costs, and permit fees.

What a house rewiring cost includes
- New wiring runs and boxes
- Outlets, switches, and fixtures
- Panel upgrade or new circuits as needed
- Wall access and patching
- Permit and inspection
What drives the cost the most
- Home size and number of circuits/outlets.
- Access — fishing wire through finished walls is labor-intensive.
- Panel capacity; a service upgrade is often bundled in.
- Removing knob-and-tube or aluminum wiring adds care and cost.
Budget, standard, and high-end scopes
The $8,973–$34,221 range maps to three common levels of finish:
| Scope | Roughly | What it covers |
|---|---|---|
| Partial | $8,973 | Specific circuits, rooms, or a panel upgrade. |
| Standard rewire | $17,893 | Most of the home, coordinated with a remodel. |
| Full + service upgrade | $34,221 | Complete rewire plus new panel and service entrance. |
How to save on a house rewiring cost
- Rewire during a remodel when walls are already open — access is most of the labor.
- Bundle the panel upgrade with rewiring to share permit and mobilization.
- Map your real load needs (EV, HVAC) before sizing the new service.
How this estimate is calculated
We start from a base cost-per-sqft for house rewiring cost and adjust it for finish quality, labor complexity, waste, and equipment, then apply national baseline indices. The figures update with the cost data and reflect mid-range, licensed-contractor pricing, not a binding quote.
