Thinking about rewiring your old house? It’s a big job, and yes, it’s a bit pricey—but it’s also one of the smartest investments you can make in your home. Old wiring can be a safety hazard, especially in homes built before modern electrical codes were established. If you’re wondering about the cost to rewire an old house, you’re in the right place.
We’re breaking down everything you need to know—from average costs to what affects the price and how you can save money without cutting corners.
Why Would You Need to Rewire an Old House?
Older homes—especially those built before the 1970s—often have outdated wiring that may no longer be safe or efficient. Common signs it might be time to rewire include:
- Flickering or dimming lights
- Frequent blown fuses or tripped breakers
- Outlets that don’t work
- Two-prong outlets (no ground wire)
- A burning smell near outlets or switches
- Aluminum wiring, which is considered a fire hazard
According to the National Fire Protection Association (NFPA), electrical problems are the second leading cause of home fires in the U.S. Rewiring isn’t just about keeping the lights on—it’s about safety.
So, What’s the Cost to Rewire an Old House?
On average, the cost to rewire an old house ranges from $4,000 to $15,000 or more. That’s a wide range, so let’s break down what affects the final price:
- Square footage of the home
- Number of rooms and outlets
- Whether walls need to be opened and repaired
- Type of wiring and materials used
- Local labor rates
- Whether the home is occupied during the job
Here’s a rough estimate by square footage:
- 1,000 sq ft: $4,000 to $6,000
- 2,000 sq ft: $8,000 to $12,000
- 3,000+ sq ft: $12,000 to $20,000+
These numbers include labor, permits, materials, and cleanup.
Factors That Affect Rewiring Costs
1. Home Layout and Accessibility
Homes with open basements or attics make the job easier and cheaper. If the walls are plaster (common in older homes), the electrician may need to cut and patch more drywall, increasing labor time and repair costs.
2. Electrical Panel Upgrade
If your panel can’t handle modern electrical loads, you’ll need a new one. A panel upgrade alone can cost $1,500 to $3,000.
3. Permit and Inspection Fees
You’ll need permits, and the work must pass inspection. Permit fees vary by city but usually range from $100 to $500.
4. Occupied vs. Vacant
It’s much faster (and cheaper) to rewire an empty house. If you’re living in the home, the electrician will need to work in sections and clean up each day, which adds to the cost.
5. Regional Labor Costs
Electricians in large cities usually charge more than those in rural areas. Expect to pay $75 to $150 per hour, depending on your location.
Can You Rewire Just Part of the House?
Absolutely. If your budget is tight or certain areas are more critical, you can focus on specific parts of the home. For example:
- Rewiring just the kitchen: $1,500 to $3,000
- Updating bedrooms or living rooms: $800 to $2,500 each
- Replacing only the outlets and switches: $500 to $1,000
This approach works well if your wiring is mostly okay but needs updating in high-use areas.
Does Homeowners Insurance Cover Rewiring?
Usually, insurance doesn’t cover preventive rewiring, but it may help if the work is related to damage from a covered event (like a fire or flood). That said, having updated wiring can reduce your insurance premiums, and some companies may even require an inspection before issuing a policy on an older home.
Tips to Save Money on Rewiring
- Get multiple quotes from licensed electricians. Don’t just go with the first bid.
- Ask about partial rewiring if the whole house isn’t in bad shape.
- Schedule the job during the off-season, like late fall or early winter, when electricians may charge less.
- Stay organized—label outlets and lights so the electrician knows what goes where.
- Tackle other upgrades at the same time (like new lighting) to save on labor.
Final Thoughts
The cost to rewire an old house might feel intimidating at first, but it’s an investment that boosts your home’s safety, value, and functionality. Plus, with proper planning and the right electrician, the process doesn’t have to be overwhelming.
Whether you plan to stay in your home long term or are thinking about selling soon, updated wiring gives peace of mind—and can literally be a lifesaver.
