How Much Does Each Part of Whole house rewiring Cost?

The cost to rewire a house in St. Louis ranges from $3,300 to $18,880, with most homeowners paying around $8,020. Your actual cost depends on several factors specific to your home and the St. Louis market.

🔌
Home Square Footage

Larger homes need more wire, more circuits, and more labor hours — cost scales roughly proportionally with square footage.

Number Of Circuits

Modern code requires dedicated circuits for kitchens, bathrooms, laundry, and outdoor areas, so a full rewire typically installs 20–40+ circuits.

📏
Wall Access

Open walls (during a remodel) cut labor costs dramatically versus fishing wire through finished walls, which may require temporary drywall removal.

🔧
Age Of Home

Pre-1960s homes often have knob-and-tube or ungrounded wiring that requires complete replacement and may reveal other code issues.

🏗️
Code Upgrades Needed

Bringing a home up to current NEC code often requires AFCI/GFCI breakers, grounding, and additional circuits beyond just replacing old wire.

The Midwest has a strong pool of skilled tradespeople, and labor rates tend to be moderate compared to coastal cities. Union and non-union shops both compete, giving homeowners options on pricing.
