The cost to rewire a house in the Triangle runs between $8,000 and $20,000 for most homes, or roughly $4 to $9 per square foot, with the typical full rewire landing around $12,000 to $15,000. The price depends on the size of your home, how old the wiring is, how easy the walls and crawl space are to access, and whether your electrical panel needs an upgrade at the same time.
Below, we break down every part of that number so you know what shapes the price before anyone opens a wall.
As a licensed electrical contractor serving Raleigh and the wider Triangle, we rewire homes that have outgrown their old wiring or are no longer safe, and we believe the price should be clear from the start. Here is what drives the cost, the signs your home may need it, and what a rewire actually involves.

- The cost to rewire a house in the Triangle usually runs $8,000 to $20,000, often near $12,000 to $15,000.
- Most rewires cost around $4 to $9 per square foot, driven by home size and access.
- A panel upgrade, often done with a rewire, adds roughly $1,500 to $3,000.

- A full rewire is permitted, inspected work that protects your home and your insurance.
How Much Does It Cost to Rewire a House in 2026?
Rewiring a house costs most Triangle homeowners $8,000 to $20,000, and the size of your home is the single biggest factor. A small home with open access sits at the low end, while a larger two-story home with finished walls and limited crawl space access sits at the top of the range.
Here is a rough guide by home size:
| Home size | Typical full rewire cost | Notes |
|---|---|---|
| Up to 1,000 sq ft | $4,000 to $9,000 | Smaller homes, fewer circuits |
| 1,000 to 2,000 sq ft | $8,000 to $16,000 | Most common Triangle homes |
| 2,000 to 3,000 sq ft | $14,000 to $22,000 | More circuits and longer runs |
| Over 3,000 sq ft | $20,000 and up | Large or multi-story homes |
These ranges assume a full rewire of the home. A partial rewire, where we replace only the unsafe or overloaded circuits, costs less and can be the right move when the rest of the wiring is sound.

What Affects the Cost of Rewiring a House?
Five factors decide where your rewire lands in that range, and most come down to your home rather than the wire itself. Knowing them helps you plan and avoid surprises.
Home Size and Number of Circuits
More square footage means more outlets, switches, lights, and circuits to run, which adds wire, materials, and labor. A larger home simply takes more time and more of everything, so it costs more than a small one.
Wall and Crawl Space Access
Open walls, an accessible attic, and a roomy crawl space make a rewire faster and cheaper. Finished walls, a slab foundation, or tight access mean more careful work to run new wire and patch afterward, which raises the price.
Age and Type of Existing Wiring
Homes with knob and tube or aluminum wiring need a full replacement for safety, which is a larger job than updating newer copper wiring. The older and more outdated the system, the more there is to remove and replace.
Panel and Service Upgrades
Many older homes pair a rewire with a panel upgrade, since the old panel often cannot support modern loads. A panel replacement adds to the total but gives your home the capacity it needs for today and the future.
Finishes and Repairs
Running new wire sometimes means opening small sections of drywall, which are patched after. The level of finish work and how much wall needs opening both affect the final number.
What Are the Signs Your House Needs Rewiring?
Your house likely needs rewiring if you have frequent breaker trips, two-prong outlets, flickering lights, or wiring that is more than about 40 years old. These are signals that the system is overloaded, outdated, or no longer safe for how you use power today.
Watch for these warning signs:
- Frequent tripped breakers or blown fuses: the system cannot handle your load.
- Two-prong, ungrounded outlets: a sign of older, unsafe wiring.
- Flickering or dimming lights when appliances turn on.
- Warm outlets or switch plates, or a burning smell: stop using them and call us right away.
- Knob and tube or aluminum wiring: common in older homes and a known safety concern.
If you notice any of these, an assessment is the safe next step. We check your wiring, panel, and grounding, then tell you whether you need a full rewire, a partial one, or a smaller repair. You can learn more about our indoor electrical work and how we approach older homes.
Can You Rewire a House Without Removing Drywall?
Yes, in many homes, we can rewire with only small, targeted openings in the drywall rather than tearing out walls. We use the attic, crawl space, and existing wall cavities to fish new wire, which keeps the patching to a minimum and the cost down.
How much wall we need to open depends on the layout, the foundation, and where the wiring runs. A home with an accessible attic and crawl space often needs only a few small cuts near outlets and switches. A slab home or one with blocked wall cavities may need more openings. During the assessment, we explain exactly what your home will need so there are no surprises.
Does Rewiring a House Include a Panel Upgrade?
A rewire does not always include a panel upgrade, but the two are often done together because an old panel may not safely support new wiring and modern loads. If your panel is undersized, outdated, or already full, upgrading it during the rewire saves you from paying twice for access and labor.
Pairing the work makes sense when:
- Your panel is a 100-amp service, and you want capacity for central air, an EV charger, or a generator.
- The panel is an older model with known safety issues.
- The breaker box is full, with no room for new circuits.
We assess the panel as part of every rewire quote, so you see whether an upgrade is needed and what it adds. If you only need the panel addressed, we can handle that on its own through our electrical panel and safety upgrades.
How Long Does It Take to Rewire a House?
A full house rewire usually takes three to ten days, depending on the size of the home and how easy the wiring is to access. A small home with open access is on the shorter end, while a large or finished home takes longer because each run is more involved.
A typical project runs like this:
- Assessment and quote: we inspect the wiring and panel and confirm the scope.
- Permit: we pull the local electrical permit before work begins.
- Rewire: we run new circuits, replace outlets and switches, and update the panel if needed.
- Inspection: the county inspector signs off, and we complete any patching.
You can usually stay in your home during a rewire, since we work area by area and keep power on where we can. We plan the sequence with you so daily disruption stays low.
Is Rewiring a House Worth the Cost?
For homes with old or unsafe wiring, rewiring is worth the cost because it removes a real fire risk and gives your home the capacity modern life needs. Whether you need a full rewire or a smaller update depends on the age and condition of your system, which is exactly what an assessment determines.
A rewire is usually worth it when:
- Your home has knob and tube or aluminum wiring that insurers and buyers flag.
- You face frequent breaker trips, or you want to add major circuits like an EV charger or generator.
- You are renovating, which is the ideal time to update wiring while the walls are open.
Beyond safety, updated wiring supports your home value, since buyers and insurers both look closely at the electrical system. A documented, permitted rewire is the kind of upgrade that pays you back in safety and resale.
Frequently Asked Questions
How often does a house need to be rewired?
Most homes need a rewire every 40 to 50 years, though the exact timing depends on the wiring type and how the home has been used. Homes with knob and tube or aluminum wiring often need it sooner, while newer copper systems can last longer with minor updates.
Is it cheaper to rewire a house during a renovation?
Yes, rewiring during a renovation is usually cheaper because the walls are already open, which removes the access and patching costs. If you are planning a remodel, it is the ideal time to update the wiring at the same time.
Can I rewire just part of my house?
Yes, a partial rewire replaces only the unsafe or overloaded circuits and costs less than a full rewire. We recommend it when the rest of your wiring is sound, and only certain areas need attention, which we confirm during the assessment.
Do I need a permit to rewire my house?
Yes, rewiring requires an electrical permit and an inspection because it is significant work that affects your home’s safety. When we handle your rewire, we pull the permit and schedule the inspection so the work is safe, legal, and documented for your insurance and resale.
Will my insurance require rewiring?
Some insurers will not cover, or will charge more for, homes with knob and tube or aluminum wiring, and a rewire can resolve that. If your insurer has flagged your wiring, an updated, permitted system often lowers your risk profile and your concerns.
