Rewiring a house can cost thousands of dollars, depending on the home’s size, the condition of the existing wiring, and how much work is needed. If your home has outdated wiring, frequent electrical problems, or an old electrical panel, you may need to budget for more than just new wires.
The good news is that understanding the costs upfront can help you plan your project and avoid unexpected expenses. HomeGuide estimates that whole-house rewiring typically costs $10,000 to $30,000, although the price can vary significantly depending on the work involved.
In this guide, I’ll break down whole-house rewiring costs by home size, explain what affects the price, and cover additional expenses such as electrical panel upgrades, permits, and wall repairs. I’ll also explain how to tell whether your home needs partial rewiring or a complete replacement, so you can make an informed decision before hiring an electrician.
How Much Does Whole-House Rewiring Cost in 2026?
Whole-house rewiring typically costs $10,000 to $30,000 in the United States, although the final price can fall outside this range depending on the home’s size, wiring condition, and labor requirements.
A smaller home with accessible wiring usually costs less to rewire. Older homes may cost more if electricians need to open finished walls, replace damaged wiring, or upgrade the electrical panel.
What Does Whole-House Rewiring Cost in Mabank, Texas?
For homeowners in Mabank, Texas, the cost of rewiring depends mainly on the property’s condition, local electrician rates, and the amount of work required. Your household budget also matters, especially if you’re balancing electrical upgrades with other home expenses. However, the local cost of living doesn’t directly determine what an electrician will charge.
If you’re planning a rewire in Mabank, request quotes from local electricians. Ask them to inspect the existing wiring and explain whether you need a complete rewire or only targeted repairs. This will give you a more realistic estimate for your home.
Before hiring an electrician, check whether the quote includes:
- Labor and wiring materials
- Outlets, switches, and electrical boxes
- Electrical panel upgrades, if needed
- Permit and inspection fees
- Drywall repairs and repainting
Not every quote covers all these items. Ask for a written, itemized estimate so you can compare contractors fairly and avoid unexpected expenses.
Whole-House Rewiring Cost by Home Size
The cost to rewire a house typically increases with its size, with estimated prices ranging from $5,000 to $17,000 for a 1,000-square-foot home and $15,000 to $51,000 for a 3,000-square-foot home. These estimates use a broad range of $5 to $17 per square foot, but actual costs depend on the home’s wiring, accessibility, and local labor rates.
| Home Size | Estimated Rewiring Cost |
| 1,000 square feet | 5,000–17,000 |
| 1,500 square feet | 7,500–25,500 |
| 2,000 square feet | 10,000–34,000 |
| 2,500 square feet | 12,500–42,500 |
| 3,000 square feet | 15,000–51,000 |
These figures are starting points for budgeting, not fixed prices. For example, rewiring a 2,000-square-foot home may cost more if the electrician needs to open finished walls, replace an outdated electrical panel, or bring parts of the system up to current code requirements.
How can you get an accurate estimate? Ask a licensed electrician to inspect your home’s existing wiring and provide an itemized quote. Make sure the estimate explains whether labor, materials, panel upgrades, permits, and wall repairs are included. This will help you compare quotes and understand the likely total cost before work begins.
What Factors Affect the Cost of Rewiring a House?
The cost of rewiring a house depends on its size, the condition of the existing wiring, access to walls and ceilings, electrician labor rates, and any additional electrical work. Understanding these factors helps you estimate your budget and compare contractor quotes.
1. Home Size and Number of Circuits
Larger homes usually cost more to rewire because they need more cable, electrical boxes, outlets, and labor. The number of circuits also matters. Kitchens, laundry rooms, bathrooms, and HVAC equipment may need dedicated circuits to meet electrical requirements.
If your electrical system struggles to handle the load, learn the signs of an overloaded electrical panel and when to arrange an inspection.
A smaller home can still have a higher rewiring cost per square foot if it has a complicated layout or requires extensive electrical upgrades.
2. Age and Condition of Existing Wiring
Old or damaged wiring can increase rewiring costs because electricians may need to replace deteriorated cables, correct unsafe connections, or update parts of the electrical system.
Older properties may also have outdated installations, so review these common electrical code violations in older homes to understand potential safety concerns.
However, an older home doesn’t always need a complete rewire. An electrician should inspect the existing system to determine whether targeted repairs or full replacement makes sense.
If you notice burning smells, discolored outlets, or frequently tripping breakers, arrange a professional inspection promptly.
3. Accessibility of Walls, Attics, and Crawl Spaces
Wiring that’s easy to access generally costs less to replace than wiring hidden behind finished walls and ceilings. Electricians may need to cut access openings to route new cables through certain parts of the house.
Attics, basements, and crawl spaces can make installation easier when they provide suitable access. Plaster walls, finished ceilings, and tight spaces may require more labor.
Ask whether the quote includes drywall repairs, plasterwork, and repainting. These expenses may be billed separately.
4. Electrician Labor Rates and Project Complexity
Electrician labor rates vary by location, experience, licensing requirements, and the complexity of the job. A straightforward rewire generally requires less time than a project involving difficult access, multiple electrical upgrades, or extensive troubleshooting.
Ask for an itemized quote that separates labor, materials, and additional work. This makes it easier to understand the price and compare estimates from different contractors.
5. Wiring Materials and Electrical Components
The cost of wiring materials depends on the home’s electrical needs, the installation method, and applicable electrical codes. A typical project may require new cables, outlets, switches, electrical boxes, connectors, and circuit breakers.
Your electrician should choose materials that suit the installation and meet local requirements. Cutting costs by using unsuitable materials can create safety risks and lead to expensive repairs later.
6. Electrical Panel Upgrades
An electrical panel upgrade can increase the total cost of rewiring, but a new panel isn’t automatically necessary for every rewire.
An electrician may recommend an upgrade if the existing panel is damaged, lacks suitable capacity for the planned circuits, or needs replacement to address safety or code requirements.
For a breakdown of the potential expense, see our guide to electrical panel upgrade cost.
Before approving the work, check whether the estimate includes the panel, breakers, grounding and bonding work, and any necessary service upgrades.
7. Permits and Inspections
Permit and inspection costs depend on local regulations and the scope of the rewiring project. Many jurisdictions require permits for substantial electrical work, followed by an inspection to verify compliance with applicable codes.
Before work begins, ask your electrician:
- Is a permit required for this project?
- Who will apply for it?
- Are permit and inspection fees included in the quote?
- Will the contractor arrange the required inspections?
Your local building department can confirm the requirements for your property. For example, the Montana Department of Labor and Industry’s electrical permit guidance explains how permit requirements apply in that state. Other states and municipalities may follow different rules.
Tip: Get at least two or three itemized quotes when practical. Compare the work included in each estimate rather than choosing a contractor based only on the lowest price.
Additional Costs to Consider When Rewiring a House
When budgeting for whole-house rewiring, remember that the cost of installing new wires may not cover every part of the project. Electrical panel upgrades, wall repairs, permits, and other improvements can increase your final bill.
Here are the main additional expenses to discuss with your electrician.
| Additional Expense | What to Expect |
| Electrical panel replacement | You may need a new panel if the existing one is damaged or unsuitable for your electrical needs. |
| New outlets and switches | Adding or relocating outlets and switches increases material and labor costs. |
| Drywall and plaster repairs | Electricians may need to open walls to access hidden wiring. Those openings may require patching. |
| Repainting | You may need to repaint walls and ceilings after repairs. |
| Grounding and bonding upgrades | The electrician may need to correct grounding or bonding issues to meet applicable safety requirements. |
| Permits and inspections | Local authorities may charge fees for permits and required inspections. |
| Smoke alarms and other safety improvements | Additional safety work may be necessary or recommended, depending on the home and local requirements. |
How can you avoid unexpected costs? Ask your electrician to itemize the estimate and identify which expenses are essential, which are optional, and which aren’t included in the quoted price. Also, confirm who will handle wall repairs and painting after the electrical work is complete.
Not every home needs these upgrades. A professional inspection will help you understand which expenses apply to your property and plan your budget more accurately.
Partial Rewiring vs. Whole-House Rewiring: Which Costs Less?
Partial rewiring usually costs less upfront than whole-house rewiring because an electrician replaces only the wiring in specific areas. However, the cheaper option isn’t always the best choice. The right solution depends on the condition of your existing wiring and whether the rest of the electrical system is safe.
Partial Rewiring
Partial rewiring costs less when the problem is limited to a specific circuit, room, or section of wiring. For example, an electrician may need to replace damaged wiring in a kitchen or repair a circuit that’s no longer safe.
This approach can reduce labor costs and limit disruption to your home. It makes sense when the remaining wiring is in good condition and can safely continue to serve your electrical needs.
However, if problems affect several circuits or large sections of the house, repeated repairs may become more expensive over time.
Whole-House Rewiring
Whole-house rewiring costs more upfront because the electrician replaces wiring throughout the property. It may be necessary when the existing wiring has widespread damage, the insulation has deteriorated, or the electrical system needs extensive updates.
A complete rewire can also make sense during a major renovation, when electricians have easier access to walls and ceilings.
The final cost depends on the home’s size, wiring accessibility, labor rates, and whether the electrical panel needs an upgrade. The HomeGuide house rewiring cost guide provides additional information about typical project costs.
Which Option Is Right for Your Home?
Choose partial rewiring when an electrician confirms that the problem is localized and the remaining system is safe. Consider whole-house rewiring when the inspection reveals widespread wiring problems or extensive replacement needs.
Before making a decision, ask your electrician to inspect the entire electrical system and explain why they recommend one option over the other. Request an itemized estimate for the necessary work so you can compare the upfront cost with the potential expense of future repairs.
The goal isn’t simply to choose the cheapest option. It’s to make your home’s electrical system safe and reliable without paying for unnecessary work.
Signs Your Home May Need Rewiring
Common signs that your home may need rewiring include frequently tripping breakers, flickering lights, damaged outlets, burning smells, and deteriorated wiring. These problems don’t always mean you need to replace the entire electrical system, but they do warrant attention from a qualified electrician.
Frequently Tripping Circuit Breakers
Circuit breakers that trip repeatedly may indicate an overloaded circuit, a short circuit, or another electrical fault. An electrician can identify the cause and determine whether you need a circuit repair, an electrical upgrade, or new wiring.
For more troubleshooting information, read our guide on why a circuit breaker keeps tripping and when to call an electrician.
Don’t keep resetting a breaker without addressing the underlying problem.
Flickering or Dimming Lights
Flickering or dimming lights can result from loose connections, overloaded circuits, or problems with the electrical supply. If the problem happens frequently, affects multiple rooms, or occurs when large appliances turn on, arrange an electrical inspection.
The issue may involve a specific circuit rather than the entire house, so have an electrician identify the cause before deciding on repairs.
Discolored or Warm Outlets
Discolored outlets, melted plastic, buzzing sounds, or unusually warm switch plates can indicate overheating and a potential fire hazard.
Stop using the affected outlet and arrange an urgent electrical inspection. Don’t remove the outlet cover or attempt repairs yourself. If you see smoke or signs of an active electrical fire, leave the property and contact emergency services.
Burning Smells or Crackling Sounds
A burning smell, crackling, or buzzing near an outlet, switch, or electrical panel may indicate a dangerous electrical fault. These warning signs can point to overheating or damaged connections.
A burning smell from an electrical outlet can indicate a serious electrical fault, so stop using the affected outlet and seek professional help.
Stop using the affected circuit if you can do so safely, and seek urgent help from a qualified electrician. If there’s smoke or fire, evacuate and call emergency services.
Outdated or Deteriorated Wiring
Old wiring may need replacement if its insulation has deteriorated, the cables are damaged, or the installation presents a safety concern. Some older homes also have knob-and-tube wiring, which may require a closer inspection.
However, the age of your home alone doesn’t mean you need a complete rewire. A qualified electrician can assess the wiring and recommend repairs, partial replacement, or whole-house rewiring based on its condition and applicable safety requirements.
For more information about electrical safety in the home, consult the Electrical Safety Foundation International (ESFI).
How Long Does It Take to Rewire a House?
Rewiring a house typically takes several days to a few weeks, depending on the home’s size, wiring accessibility, and the amount of electrical work required. A small home with accessible wiring may take less time, while a larger home with finished walls or extensive electrical problems may take longer.
What Happens During a Whole-House Rewiring Project?
A whole-house rewire usually involves six main steps:
- Inspection and planning: The electrician inspects the existing wiring, identifies safety issues, and plans the replacement work.
- Preparing the electrical system: The electrician safely disconnects the circuits that need to be replaced.
- Installing new wiring: New cables, electrical boxes, and circuit connections are installed throughout the house.
- Completing electrical upgrades: The electrician upgrades the panel, grounding, or other components if needed.
- Testing and inspection: The electrician tests the new wiring and arranges any required inspections.
- Repairing walls and ceilings: Openings made during installation are patched and finished. Painting may also be necessary.
Can You Stay in Your Home During Rewiring?
You may be able to stay in your home during rewiring, but it depends on the project’s scope and how long the electricity will be unavailable. Some projects allow work in stages, while others may require temporary power shutdowns or make parts of the house difficult to use.
Before work begins, ask your electrician how long the project is expected to take, which areas will be affected, and when the power will be switched off. Also, confirm whether wall repairs and painting are included in the schedule or handled separately.
Tip: Plan for possible delays, especially if the electrician finds damaged wiring or other problems after opening the walls.
Does Rewiring a House Require a Permit?
Yes, whole-house rewiring often requires an electrical permit and inspection, but the rules depend on your location and the scope of the work. Check your local building requirements before starting the project.
Before hiring an electrician, ask:
- Is a permit required? Confirm whether your project needs one.
- Who will handle the permit? Find out whether the electrician will apply for it.
- Are inspections required? Ask when the electrical work needs to be inspected.
- Are permit fees included? Check whether the quote covers permit and inspection costs.
- Will I receive documentation? Request copies of the permit and inspection records when the work is complete.
Why Are Permits and Inspections Important?
Permits and inspections help ensure that electrical work meets local safety requirements. They can also identify problems before you start using the new wiring.
If you’re rewiring a home in Mabank, Texas, contact the local building department to confirm which permits and inspections you need. Don’t assume that every project follows the same rules.
Tip: Ask your electrician to explain the permit process and include any related fees in the written estimate. This helps you avoid unexpected costs and delays.
How to Save Money on Whole-House Rewiring
You can save money on whole-house rewiring by comparing detailed quotes, planning electrical work ahead of time, and coordinating the project with other renovations. However, don’t cut corners on wiring materials, safety requirements, or qualified labor just to lower the price.
Get Multiple Itemized Quotes
Request two or three quotes from licensed electricians when possible. Each quote should explain the labor, materials, wiring replacement, panel upgrades, permits, and wall repairs included in the price.
Compare the work each electrician proposes, not just the total cost. A cheaper quote may leave out important expenses that you’ll have to pay for later.
Combine Rewiring With Home Renovations
If you’re already remodeling your home, consider scheduling rewiring during the renovation. Electricians may have easier access to wiring when walls and ceilings are already open, which can reduce additional labor and repair costs.
Coordinate the schedule with your renovation contractor to avoid paying for the same work twice.
Make Wiring Easier to Access
Accessible attics, basements, and crawl spaces may help electricians install new wiring with less disruption. This can reduce the need to open finished walls and ceilings.
Ask your electrician whether your home’s layout offers these opportunities. Never sacrifice proper wire protection or installation standards to save money.
Plan Outlet and Switch Locations Before Work Begins
Decide where you want outlets, switches, lighting controls, and dedicated appliance circuits before installation starts. Making these decisions early can help prevent costly changes later.
Tell your electrician about your current and future electrical needs, including major appliances and home office equipment. This helps ensure the new wiring supports how you use your home.
Address Electrical Problems Early
Fixing electrical problems promptly can help prevent further damage and reduce safety risks. If an electrician identifies damaged wiring or unsafe connections, ask which repairs need immediate attention.
You may not need to rewire the entire house. A professional inspection can help determine whether targeted repairs or a complete rewire makes more sense for your home.
Final tip: The best way to control rewiring costs is to plan carefully, compare quotes, and understand exactly what’s included. Keep safety as your priority, and ask your electrician to explain any recommended upgrades before approving additional work.
How to Choose an Electrician for Whole-House Rewiring
Choose an electrician who has the required license and insurance, experience with whole-house rewiring, and a clear written estimate. The lowest quote isn’t always the best value, especially if it leaves out important work or uses unsuitable materials.
Before hiring an electrician, check the following:
1. Check Their License and Insurance
Make sure the electrician meets your local licensing requirements and carries appropriate insurance. This helps protect you if an accident or property damage occurs during the project.
2. Ask About Whole-House Rewiring Experience
Choose an electrician who has handled similar projects, particularly if your home has old wiring or difficult-to-access walls and ceilings. Ask how they plan to replace the wiring and handle any problems they find.
3. Request a Detailed Written Estimate
Ask for an itemized quote that covers labor, wiring materials, outlets, switches, and any electrical panel upgrades. It should also identify additional costs, such as permits, inspections, and wall repairs.
A detailed estimate makes it easier to compare contractors and understand what you’re paying for.
4. Confirm Permit and Inspection Responsibilities
Ask whether your project requires a permit and who will arrange the necessary inspections. Your electrician should explain the process and clarify whether the related fees are included in the estimate.
5. Ask About Wall Repairs and Cleanup
Rewiring may require openings in walls or ceilings to access existing cables. Confirm whether the electrician will repair those openings, handle cleanup, or leave the finishing work to another contractor.
6. Review Warranties and Payment Terms
Ask whether the electrician provides a workmanship warranty and whether the materials carry separate warranties. Also, agree on the payment schedule and how the contractor will handle unexpected work.
Before making your decision, compare at least two or three quotes when practical. Choose the electrician who explains the work clearly, addresses your concerns, and provides a written scope of work with no major uncertainties.
