The cost to install a whole new wiring system in a house is highly variable, typically ranging from $8,000 to $30,000 or more. The final price depends on the home's size, accessibility of walls, the complexity of the electrical panel upgrade, local labor rates, and the quality of materials chosen. A full rewire is a major project that involves running new cables throughout the structure, updating the service panel to meet modern electrical demands, and ensuring full compliance with the National Electrical Code (NEC). For a detailed breakdown of the process and factors affecting price, we recommend reading our internal article, Electrical System Rewiring. Always obtain multiple quotes from licensed and insured electricians.
The cost to rewire an entire home varies significantly based on size, location, and scope. For an average 1,500 to 2,000 square foot house, homeowners can expect a range of $4,000 to $12,000, with a national average often cited around $8,000. Key factors include the home's age and accessibility of walls, the type of wiring and number of circuits required, and local labor rates. Upgrading to a modern 200-amp service panel adds $1,500 to $3,000. Permits and inspections are also necessary costs. Given the complexity and critical safety nature of electrical work, obtaining multiple detailed quotes from licensed and insured electricians is essential for an accurate project estimate.
The duration of a full electrical rewire for a typical three-bedroom house generally takes between 5 to 10 days for a professional team. This timeframe can vary significantly based on the property's size, age, and complexity. Older homes with solid walls or intricate layouts require more labor-intensive work like chasing walls for new cables, which extends the timeline. A thorough process includes removing old wiring, installing new circuits, backboxes, and consumer units, followed by plastering, testing, and certification. Proper planning and allowing electricians unimpeded access are crucial to avoid delays. Rushing the job compromises safety, so a methodical approach adhering to wiring regulations is essential.
Yes, a house can often be rewired without removing all the drywall, using techniques known as "fishing" or "retrofitting." Electricians use specialized tools like flexible drill bits, fish tapes, and fiberglass rods to pull new wiring through existing wall cavities, often from access points in the attic, basement, or through strategically cut small holes. These holes can be made at the top and bottom of walls and are later patched and repainted. This method is standard for updating electrical systems in finished homes, minimizing demolition and repair costs. However, it is more complex and time-consuming than wiring during construction, and some situations, like fireblocked walls or complex layouts, may require more extensive access.
