Partial vs Whole-Home Rewire: What's the Difference?

Not every aging home needs a full rewire. A partial rewire targets the highest-risk circuits while a whole-home rewire replaces everything. Choosing the right scope saves money and risk.

🔧

Partial Rewire

Replaces specific problem circuits - usually the kitchen, bathroom, and any knob-and-tube or aluminum runs. Lower cost, less disruption.

🏠

Whole-Home Rewire

Replaces all branch wiring, outlets, and switches throughout. Best for homes with pervasive old or unsafe wiring.

📊

How We Decide

We map every circuit, identify wiring type per room, and recommend the minimum scope that meets code and safety.

Cost & Scope

Choosing the Right Scope

Localized issues

Frequent problems in one area? A partial rewire likely solves it.

Systemic old wiring

Knob-and-tube or aluminum throughout? A whole-home rewire is the safe path.

Renovation timing

If you're already opening walls for a remodel, bundle a full rewire to save on labor.

Questions

Partial vs Full Rewire FAQ

How much does a partial rewire cost? ▾

Typically $3,000-$8,000 depending on the number of circuits and accessibility, versus $10,000-$25,000 for a full home.

Can a partial rewire pass inspection? ▾

Yes, as long as the replaced circuits meet current code and any unsafe wiring is addressed. The inspector checks what we touch.

Will a partial rewire leave old wiring elsewhere? ▾

Yes - only targeted circuits are replaced. We document remaining older wiring so you know the home's full profile.

Is a full rewire worth it for resale? ▾

Often. Updated wiring is a strong selling point and can resolve insurance issues that old wiring creates.

Do you bundle rewiring with a panel upgrade? ▾

Frequently. Combining them in one project reduces labor and inspection cycles - ask us for a combined quote.
