Rewiring a house is one of those projects that often starts with a simple question: “What is the cost of rewiring a house?” Whether you’re renovating an older home, upgrading for safety, or preparing for new appliances, understanding the financial and technical aspects of rewiring is essential. It’s not just about replacing wires — it’s about protecting your home, meeting code requirements, and planning for long-term functionality.
This guide is for homeowners, property managers, and anyone considering an electrical overhaul. With insights from Timothy Santos Electric, a trusted name in residential electrical services in Tewksbury, Massachusetts, we’ll walk through the key factors that influence cost, what to expect during the process, and how to make informed decisions.
Why Rewiring Matters
Older homes often come with outdated electrical systems. Knob-and-tube wiring, aluminum conductors, or overloaded circuits can pose serious risks. Flickering lights, warm outlets, and frequent breaker trips are signs that your wiring may need attention. Rewiring ensures your home meets current safety standards and supports modern electrical loads.
Entities like circuit breaker, fuse box, copper wire, and National Electrical Code (NEC) are central to this topic. These standards define how electrical systems should be installed and maintained across the United States.
What Is the Cost of Rewiring a House?
The cost of rewiring a house varies widely depending on several factors. On average, homeowners can expect to pay between $4,000 and $15,000 for a full rewiring project. Smaller homes may fall on the lower end, while larger properties or those with complex layouts may require more labor and materials.
Let’s break down the key elements that influence pricing.
Home Size and Layout
One of the biggest factors is square footage. A compact home under 1,000 square feet may cost around $4,000 to $6,000 to rewire. Medium-sized homes between 1,000 and 2,000 square feet typically range from $6,000 to $10,000. Larger homes can exceed $15,000, especially if multiple stories or additions are involved.
Homes with finished walls, tight crawl spaces, or limited attic access may require more time and effort, increasing labor costs.
Age and Condition of Existing Wiring
If your home still uses knob-and-tube or aluminum wiring, replacement is often necessary. These systems are not compatible with modern appliances and may fail inspection. Removing old wiring and installing new circuits adds time and complexity to the job.

Materials and Components
Rewiring involves more than just wire. Electricians install new outlets, switches, junction boxes, and sometimes upgrade the electrical panel. Copper wire is the standard choice due to its conductivity and durability. The cost of materials depends on the number of circuits, outlets, and fixtures required.
Drywall repair may also be needed if walls are opened to access wiring. This adds to the overall budget, especially in homes with plaster or decorative finishes.
Labor and Electrician Rates
Licensed electricians typically charge between $65 and $120 per hour, depending on location and experience. A full rewiring project may take several days to complete, especially if the home is occupied during the work.
Timothy Santos Electric offers transparent pricing and works with homeowners to develop realistic timelines.
Permits and Inspections
Electrical work must comply with local building codes. This means obtaining permits and scheduling inspections. Permit fees vary by municipality but usually range from $100 to $500. Inspections ensure the work meets NEC standards and is safe for occupancy.
Skipping this step can lead to fines or complications when selling your home. Always work with a licensed contractor who understands local requirements.
Additional Costs to Consider
- Electrical Panel Upgrade: If your current panel cannot support new circuits, an upgrade may be necessary. This can add $1,000 to $3,000 to the project.
- Smart Home Integration: Adding smart switches, outlets, or lighting systems increases material costs.
- Temporary Power Solutions: If you need to stay in the home during rewiring, temporary setups may be required to maintain essential services.
