Understanding the Cost to Rewire a House: A Comprehensive Guide

cost to rewire a house

A house’s electrical system is an integral part of modern living. Over time, however, electrical wiring can deteriorate, becoming outdated and unsafe. In such cases, rewiring becomes necessary to ensure the safety and efficiency of the electrical system. However, rewiring a house is a significant undertaking that requires careful planning and budgeting. This comprehensive guide will explore the various factors contributing to the cost of rewiring a house.

Size of the House

The size of the house is a crucial factor in determining the rewiring cost. Larger houses generally require more materials and labor, resulting in higher prices. Additionally, multi-story homes or houses with complex layouts may require additional wiring to ensure proper coverage, increasing the overall cost.

Accessibility of Wiring

The accessibility of the existing wiring also affects the cost. If the wiring is easily accessible through an attic or crawl space, the cost of house rewiring tends to be lower. However, if the wiring is concealed within walls or buried underground, it will require more effort to access and replace, thus increasing the cost.

Electrical Panel Upgrade

In many cases, rewiring a house may require upgrading the electrical panel to accommodate the increased electrical load. Older homes often need updated panels that can handle the power demands of modern appliances and electronics. The cost of panel upgrades should be factored into the overall rewiring budget.

Wiring Materials

The choice of wiring materials can significantly impact the cost. Copper wiring is the most commonly used material due to its durability and reliability. Although more expensive than aluminum, copper wiring is a better long-term investment. Consider your budget and specific requirements with your electrician to determine the most suitable wiring material for your house.

Number and Type of Outlets and Switches

The number and type of outlets and switches in your house can affect the rewiring cost. Adding or replacing outlets and switches requires additional wiring work. If you upgrade to modern outlets with USB ports or intelligent controls, the cost will be higher than standard options. Take into account your electrical needs and preferences when budgeting for these upgrades.

Labor Costs

Labor costs can vary depending on the electrician’s experience, location, and the complexity of the rewiring project. It’s essential to hire a licensed and reputable electrician who will ensure the job is done safely and up to code. Obtain multiple quotes from different electricians to compare prices and services before deciding.

Permits and Inspections

Rewiring a house often requires obtaining permits and passing inspections to comply with local building codes. The cost of tickets and inspection fees should be considered in your budget. Working with a professional electrician familiar with the local regulations can help streamline this process.

Additional Considerations

Several additional factors may contribute to the overall cost of rewiring a house. These include replacing outdated fixtures, repairing any damage to walls or ceilings caused by rewiring work, and installing surge protection devices or ground fault circuit interrupters (GFCIs) for added safety.

Regarding cost, rewiring a house can range anywhere from a few thousand dollars to tens of thousands, depending on the abovementioned factors. Getting multiple quotes from qualified electricians is crucial to get an accurate estimate based on your specific requirements.

While the cost of rewiring a house may seem daunting, it is a worthwhile investment in the safety and functionality of your home. Rewiring ensures the proper functioning of your electrical system, reduces the risk of electrical fires, and improves energy efficiency.


Understanding the cost to rewire a house involves considering various factors such as the size of the house, accessibility of wiring, electrical panel upgrades, wiring materials, outlets and switches, labor costs, permits and inspections, and any additional considerations.
