Average Cost to Rewire an Entire House: A Comprehensive Guide

Rewiring an entire house is a significant home improvement project that ensures electrical safety and meets modern power demands. Understanding the average cost to rewire an entire house is crucial for budgeting and planning. This guide explores the factors influencing the cost, breakdowns by room or project size, and tips to save money.The average cost to rewire an entire house typically ranges between $3,500 and $20,000, depending on various factors. Below, we delve into the details to help you estimate your specific needs.

1. House Size and Layout: Larger homes require more materials and labor, increasing the overall cost. For example, a 1,500-square-foot home may cost $4,000–$8,000, while a 3,000-square-foot home could range from $8,000–$15,000.
2. Type of Wiring: Older homes with knob-and-tube wiring are more expensive to rewire ($5,000–$20,000) due to the complexity of removal and replacement. Modern NM (non-metallic) wiring is cheaper ($3,500–$10,000).
3. Labor Costs: Electricians charge $50–$100 per hour, and rewiring a house can take 50–100 hours, depending on the project’s scope.
4. Permits and Inspections: Local building codes may require permits ($100–$500) and inspections ($200–$800), adding to the total cost.
5. Additional Upgrades: Upgrading the electrical panel ($1,200–$2,500) or adding GFCI outlets ($150–$250 per outlet) will increase expenses.

Here’s a breakdown of average rewiring costs by room:

• Kitchen: $1,200–$3,000 (due to high-power appliances and GFCI requirements).
• Bathroom: $800–$2,000 (GFCI outlets and ventilation fans).
• Living Room/Bedroom: $500–$1,500 per room (standard outlets and lighting).
• Basement/Attic: $1,000–$3,000 (additional wiring for finished spaces).

To save money on rewiring, consider these tips:

• Combine Projects: If renovating, rewire during demolition to reduce labor costs.
• Get Multiple Quotes: Compare prices from licensed electricians to find the best deal.
• Use Standard Materials: Avoid premium wiring unless necessary for high-power needs.
• DIY Partial Work: Homeowners can handle minor tasks like removing old wiring (if permitted by local codes).

Rewiring an entire house is a long-term investment in safety and functionality. By understanding the average costs and planning accordingly, you can ensure a smooth and cost-effective project.
