How much does it cost to rewire a house per square foot?

House rewiring cost per square foot isn’t a reliable figure; electricians price the project after an on-site inspection of your existing wiring and the work required. The biggest swing in cost comes from the wiring you have now and how easy it is to access it without major demolition. We inspect older homes, identify issues like knob-and-tube or aluminum wiring, and provide a written report with recommendations and any needed upgrades such as panel work, added circuits, or whole-home surge protection. Our team regularly handles older-home rewiring in the Summit area, so we tailor scope to the home instead of a blanket per‑foot rate. Pros rarely bid “by the foot” because circuits, access, and upgrades drive labor more than square footage.

Expect your quote to reflect:

• Existing wiring type and condition
• Access (open framing vs finished walls/ceilings)
• Required upgrades (panel capacity, new circuits, EV, surge protection)
• Project scope (partial areas vs full‑home)
