How much does whole house electrical rewiring cost on average?

Whole-house rewiring cost is quoted by Castle Electric Inc. only after an on-site inspection with a clear, upfront scope, timeline, and price. Costs vary most with the size of the home and how much outdated wiring must be safely removed and replaced. We’ll provide you with a detailed, straightforward scope of work, timeline, and upfront pricing; we never hit you with hidden fees or pages of industry jargon. We routinely price full rewires in and around Plainville, and our licensed team completes final testing and documentation helpful for insurance or resale. In older homes, the routing that lets us fish new cable with minimal wall openings often saves more than any single material choice. Financing is available for larger projects.

Key factors that influence your quote:

• Square footage and number of circuits to rewire
• Access to walls, attic, and basement for cable runs
• Panel upgrade needs and added dedicated circuits (EV, kitchen, office)
• Patching and restoration scope after install
