What affects the cost
Rewiring cost depends on size, access, and scope:
- Home square footage and number of circuits
- Whether walls are open (during a remodel) or finished
- Panel and service upgrade (100A to 200A)
- Old knob-and-tube or aluminum wiring removal
Why access matters most
Running new wire is far cheaper when walls are open during a remodel. In a finished home, electricians must fish wire through walls and patch afterward, which adds significant labor.
