How much does house rewiring cost per square foot?

House rewiring is rarely sold as a simple price per square foot; electricians price it by scope and confirm final cost after an on-site assessment. The biggest cost drivers are how accessible your existing wiring is and what code upgrades are required to make the home safe. Our licensed in-house team often finds that labor, not materials, sets the budget on older homes. We regularly complete full-home rewires in the Shrewsbury area. In plaster-and-lath houses, for example, time is set by how cleanly we can fish new cable without opening walls.

What most affects your final price:

• Open walls vs finished walls and attic/crawl access
• Required code upgrades (AFCI/GFCI, tamper-resistant receptacles) and new circuits
• Panel or service upgrade needs and permit/inspection fees
• Extent of replacement (targeted circuits vs full home)

Schedule a walkthrough so we can define the circuits and provide a clear written proposal.
