How much does it cost to rewire a whole house professionally?

A whole‑house rewiring is priced only after an on‑site assessment because cost depends on home size, access to wiring, code upgrades, and material choices. The biggest cost driver is usually how many circuits need replacement and whether walls or ceilings must be opened, followed by any panel or service upgrades and safety devices. Many homes don’t require a full gut; targeted circuit rewiring or device updates can address hazards, and our technicians explain options before work begins. We provide upfront, written estimates with no surprise fees, and we regularly handle rewiring projects in the Westerville area.

Typical factors that change the price:

• Square footage and number of rooms/circuits
• Access conditions (open basements/attics vs finished plaster or tight spaces)
• Panel or service capacity changes (100–400 amp) plus meter/mast work
• Added scope like new outlets, grounded wiring, AFCI/GFCI protection, or surge protection

Ask a licensed electrician to inspect and deliver a written scope and price before you commit to full rewiring. <br/> Updated: 2026-03-28 <br/> Need help in Westerville, OH?
