Whole-House Rewiring Cost: What Electricians Should Charge
Electricians should charge $8,000–$20,000 for a whole-house rewire of a typical 1,500–2,500 sq ft home. Smaller homes with accessible wiring paths run $6,000–$10,000, while larger or multi-story homes with plaster walls and limited access can reach $15,000–$30,000. Labor typically represents 60–70% of the total cost.
Whole-house rewiring is one of the most labor-intensive and profitable jobs in residential electrical work. Older homes with knob-and-tube, aluminum, or cloth-insulated wiring are prime candidates, and demand is strong as homeowners modernize for safety and insurance requirements. Pricing accurately requires a thorough assessment of the home's size, construction type, and the accessibility of wiring paths.
When Is a Whole-House Rewire Necessary?
A whole-house rewire is needed when the existing wiring poses a safety hazard or cannot support modern electrical loads. Common triggers include knob-and-tube wiring (pre-1950s homes), aluminum branch circuit wiring (1965–1973 era), cloth-insulated wiring with deteriorating insulation, undersized circuits that trip frequently, and insurance company requirements. During your initial walkthrough, check the panel type, inspect visible wiring in the attic and basement, test outlets for grounding, and note the number of existing circuits. A typical 1960s home might have 8–12 circuits — a modern rewire should provide 20–30 circuits minimum. Document everything with photos for your estimate.
Material Cost Breakdown
Wire is your biggest material expense. A typical 2,000 sq ft home requires 1,500–2,500 feet of Romex NM-B cable across various gauges: 14/2 for 15A lighting circuits ($0.35–$0.55/ft), 12/2 for 20A outlet circuits ($0.50–$0.75/ft), 10/3 for dryer and appliance circuits ($1.50–$2.50/ft), and 6/3 for ranges and subpanels ($3.50–$5.00/ft). You will also need a new panel — a Square D Homeline or Eaton BR 200A panel runs $250–$500 wholesale with breakers adding $200–$400. Budget $500–$1,000 for devices: receptacles (Leviton or Hubbell at $1–$3 each), switches, cover plates, junction boxes, wire staples, and connectors. Total materials typically run $2,500–$5,000 depending on the home size and circuit count.
Labor Hours and Crew Sizing
A whole-house rewire of a 2,000 sq ft single-story home with an accessible attic and basement takes 40–60 labor hours. Two-story homes without accessible wall cavities can take 60–100 hours. Most electricians run a two-person crew: a journeyman handling panel work, circuit design, and critical connections, with an apprentice pulling wire, mounting boxes, and installing devices. A two-person crew can typically complete a standard rewire in 3–5 working days. Your labor rate should cover overhead, insurance, and profit — $85–$150 per hour for a journeyman and $40–$75 for an apprentice, depending on your market. In high-cost markets like the Northeast or West Coast, labor alone on a rewire can reach $10,000–$15,000.
Wiring Access Methods and Their Cost Impact
The single biggest variable in rewiring cost is wall access. Open-wall rewires (where drywall is already removed for renovation) cut labor time by 30–40% because you can see framing and drill freely. Homes with accessible attics and basements or crawl spaces allow you to fish wires vertically through wall cavities from above or below — this is the standard approach. Plaster-and-lath walls in pre-war homes are the most challenging: the lath blocks fishing, and cutting access holes for every run is time-intensive. Budget an extra $2,000–$5,000 for plaster wall homes. For slab-on-grade homes with no basement, you may need to surface-mount conduit in some areas or route through the attic and down — add 15–25% to your labor estimate. Always discuss drywall repair with the homeowner upfront — clarify whether patching is included in your scope or handled by a drywall contractor.
Permits, Code Requirements, and Inspections
Whole-house rewiring requires a permit in every jurisdiction and typically involves multiple inspections: a rough-in inspection before walls are closed up, and a final inspection after devices are installed and the panel is energized. Permit fees range from $150–$600 depending on jurisdiction. Current NEC requirements you must meet include: AFCI protection on all habitable room circuits, GFCI protection in kitchens, bathrooms, garages, basements, and outdoors, tamper-resistant receptacles throughout, and proper grounding and bonding. Many jurisdictions also require smoke and CO detector circuits. Build these code requirements into your material list and labor estimate from the start — they add $500–$1,500 in materials and 4–8 hours of labor compared to a basic rewire.
Pricing Strategy and Presenting the Estimate
Target 45–55% gross margin on whole-house rewires. Break your estimate into clear sections: panel upgrade (if needed), rough-in wiring by zone (kitchen, bedrooms, living areas, bathrooms), device installation, permit and inspection fees, and any drywall patching if included. Offering a good-better-best approach works well: the base option covers code-minimum rewiring, the mid-tier adds dedicated home office circuits, USB outlets in key locations, and outdoor receptacles, while the premium tier includes smart switch pre-wiring, whole-house surge protection, and structured wiring for networking. The upsells can add $2,000–$5,000 to the job with proportionally less labor. Collect 40–50% deposit before starting and milestone payments at rough-in completion and final inspection.
Frequently Asked Questions
A standard 2,000 sq ft home with accessible attic and basement takes 3–5 working days with a two-person crew. Larger homes, multi-story homes without access, or plaster-wall homes can take 5–10 days. Factor in an additional 1–3 days for inspection scheduling and any utility coordination needed.
