Is It Expensive to Rewire an Entire House?
Conclusion
Homeowners often hesitate when they hear the words “whole house rewiring.” The first thought that comes to mind is cost and that’s understandable. Rewiring a home is a significant project, but it’s also one of the most important investments you can make in safety, reliability, and long-term property value
In Florida, especially in older areas around Tampa and Polk County, many homes still operate with outdated wiring that struggles to handle today’s modern electrical demands. At Keentel Electrical Contractors, we specialize in rewiring projects that bring your electrical system up to code while keeping costs transparent and manageable.
If you’ve ever wondered,
“Is it expensive to rewire an entire house?”, this detailed guide explains everything you need to know from cost factors to savings tips and when a full rewire is truly necessary.
Why Home Rewiring Matters
Before talking about cost, it’s essential to understand why rewiring matters. A complete rewire is not just about upgrading wires it’s about protecting your home and family from potential electrical hazards.
Reasons homeowners choose to rewire:
- Safety: Prevent electrical fires caused by old, frayed, or aluminum wiring.
- Capacity: Modern homes use more power than systems built 30–40 years ago can handle.
- Code Compliance: New wiring ensures your home meets Florida’s latest safety and energy regulations.
- Property Value: A newly rewired home is more appealing to buyers and increases resale potential.
- Peace of Mind: You eliminate the risk of flickering lights, tripped breakers, and overheating outlets.
Average Cost to Rewire a House in Florida
The cost of rewiring an entire house depends on size, accessibility, material choice, and additional upgrades. On average, Florida homeowners can expect to pay between $8,000 and $20,000
for a complete rewiring project.
Here’s a closer look at
typical cost ranges by home size:
Home Size Estimated Cost (USD) Project Duration
Small home (1,000 sq. ft.) $6,000 – $9,000 4–6 days
Medium home (1,500–2,000 sq. ft.) $9,000 – $14,000 1–2 weeks
Large home (2,500+ sq. ft.) $14,000 – $20,000+ 2–3 weeks
These prices include materials, labor, permits, and safety inspections. If your panel or outlets also need replacement, that may add to the final cost.
Main Factors Affecting Rewiring Cost
1. House Size and Layout
Larger homes require more wiring, outlets, and labor hours. Multi-story homes or those with attics and crawl spaces take longer due to accessibility challenges.
2. Age of the Electrical System
Older homes with aluminum or knob-and-tube wiring require careful removal and replacement. The older the system, the more complex and costly the job becomes.
3. Wiring Type and Material Quality
Copper wiring is preferred for safety and conductivity, but it costs slightly more than aluminum. The investment pays off in durability and long-term performance.
4. Electrical Panel and Circuit Upgrades
If your electrical panel is outdated or undersized, it must be upgraded to support modern usage. This adds around $1,500–$3,000 depending on amperage.
5. Permits and Inspections
Florida law requires proper permits for major electrical work. At Keentel Electrical Contractors, we handle all permitting and inspection processes, ensuring your project meets Polk County and Tampa regulations.
6. Accessibility of Wiring
Wiring hidden behind finished walls or in tight attic spaces takes more time to replace. Homes under renovation are usually less expensive to rewire because walls are already open.
7. Special Features and Customization
Adding smart home technology, additional outlets, or high-capacity circuits for EV chargers increases both material and labor costs.
How Electricians Estimate Rewiring Costs
A professional estimate includes several stages:
- Initial Inspection: Electricians evaluate your current wiring, panels, and overall system condition.
- Load Calculation: Engineers calculate how much electrical load your home requires for safe operation.
- Material Planning: Based on findings, they select the best wiring type, breakers, and grounding systems.
- Labor & Permits: The estimate covers all installation, testing, and local permit fees.
Our Electrical Engineering Services team performs accurate assessments to ensure your estimate reflects real needs—not inflated costs.
Is It Worth the Cost?
Many homeowners initially hesitate because rewiring sounds expensive, but the long-term benefits outweigh the upfront expense.
Key advantages include:
- Improved safety: Eliminates fire and shock hazards.
- Increased home value: Buyers prefer homes with new, code-compliant electrical systems.
- Energy efficiency: Modern wiring reduces energy loss and improves circuit performance.
- Insurance savings: Some insurers offer lower premiums for newly rewired homes.
In short, rewiring is not just a cost it’s an investment that protects your home and can even save money over time.
Rewiring vs. Partial Electrical Upgrades
Not every home needs a full rewire. Sometimes a partial upgrade is enough, especially if only specific circuits or rooms are outdated.
Partial rewiring may be suitable when:
- Only one section of the home shows electrical issues.
- The existing wiring is modern and grounded.
- You’ve already upgraded your panel within the last 10 years.
However, if your wiring is more than 30–40 years old, or you experience frequent breaker trips,
a full house rewire is the safest and most future-proof choice.
Signs You Need to Rewire Your Home
Not sure whether it’s time for a full rewire? Watch for these common signs:
- Flickering lights or dimming when using multiple devices.
- Frequent breaker trips or blown fuses.
- Discolored or warm outlets and switches.
- Buzzing sounds behind walls or in outlets.
- Outdated two-prong outlets without grounding.
- Aluminum or cloth-covered wiring in older homes.
If you notice any of these warning signs, schedule a professional inspection immediately. Our About Us page explains how our licensed electricians maintain strict safety standards across all projects.
How to Save Money on Rewiring Projects
Rewiring doesn’t have to break the bank. Here are several cost-saving tips:
- Combine Projects: If you’re renovating or repainting, rewire while walls are already open.
- Plan Ahead: Adding future circuits during the rewire can prevent another upgrade later.
- Request a Detailed Quote: Ensure the quote includes materials, labor, permits, and inspection costs.
- Avoid DIY Work: Poorly executed DIY wiring can double repair costs later.
- Choose Local Electricians: Hiring local Tampa or Polk County professionals reduces travel and overhead fees.

Can You Live in Your House During a Rewire?
In most cases, yes but with some temporary inconvenience. Electricians rewire the house in stages, cutting power to only certain areas at a time
What to expect during the process:
- Temporary loss of power in rooms being rewired.
- Limited access to outlets or lighting during work hours.
- Coordination with your electrician to plan safe living arrangements.
For large homes or complex layouts, short stays elsewhere may be recommended for convenience.
Rewiring Old Homes: Special Considerations
Older Florida homes often have structural and electrical quirks that require extra care. Common challenges include plaster walls, non-grounded systems, and restricted attic access.
Our technicians use non-invasive methods to minimize wall damage and preserve your home’s appearance while safely upgrading the wiring. Learn more about our regional experience through Polk County Electrical Services.
