Rewiring a whole house typically costs about
$10,000 to $30,000, or roughly
$5 to $17 per square foot for older homes with finished walls. Partial rewires, like replacing the active knob-and-tube circuits first, cost less and are often the right place to start. Want help? See our
home rewiring service.
Typical Price Ranges
| Job | Typical LA range |
|---|
| Whole-house rewire (older home, finished walls) | $10,000 to $30,000 |
| Per square foot (older, closed walls) | $5 to $17 |
| Per square foot (open framing, remodels) | $2 to $4 |
| Partial rewire (priority circuits) | Quoted per job, less than a full rewire |
Ranges are typical published 2026 averages for the Los Angeles area, not a quote. Your price depends on your home. Ready Electric gives you a written price before any work starts, and the service call fee is waived when you approve the work.
Why Older LA Homes Cost More
Plaster walls, original trim, tight attics and crawl spaces, and wiring added by several owners over 80 to 100 years all add time. Homes with knob-and-tube often need the whole system brought up to code, including grounding and GFCI protection.

What Drives the Price
- Size of the home and number of circuits
- Attic and crawl space access
- Plaster vs. drywall
- Partial vs. whole-house
- A panel upgrade at the same time
- Permits and wall patching
Phasing the Work
Many homeowners replace the most-used circuits first, such as the kitchen, bathrooms and laundry, then finish the rest later. It spreads the cost and still removes the biggest risks. Financing is available for qualifying customers.
