One of the most common questions homeowners ask is: What is the cost to rewire a house from knob and tube? This article will break down the factors influencing the cost, the process involved, and tips to manage expenses.Knob and tube wiring was commonly used in homes built before the 1950s. While it was innovative for its time, this outdated system poses significant safety risks, including fire hazards and insufficient capacity for modern electrical demands. Rewiring your home is not just a matter of convenience but also a critical safety upgrade.Here are the key factors that influence the cost to rewire a house from knob and tube:
- Home Size and Layout: Larger homes with complex layouts require more materials and labor, increasing the overall cost.

- Permits and Inspections: Most jurisdictions require permits and inspections, which add to the total expense.
- Additional Upgrades: You may need to upgrade your electrical panel or add new outlets, further increasing costs.
On average, homeowners can expect to pay between $3,000 and $10,000 to rewire a house from knob and tube. However, larger or more complex projects can exceed $15,000. Below is a breakdown of typical costs:
