House Rewiring Cost

How much does it cost for an Electrician to Rewire a House?

You can do a lot of residential renovations and repairs to your home, but rewiring it wouldn’t make it look any better. Nevertheless, updating the house’s electrical systems and wiring is essential. You can have serious, even fatal, consequences if you do not upgrade the wiring in your home when necessary.


Ensure that your home’s wiring is in proper working condition. Depending on the size of your home, rewiring can be expensive. But neglecting rewiring needs can be even more costly in the long run.


Charlie Sparks is a team of certified electricians who are experts at rewiring the house effectively and efficiently.


This blog will highlight the costs involved in rewiring a house depending on different factors and wire type.

Factors that Affect the Cost of Rewiring your House

To rewire your home, you need to determine how many rooms need rewiring, the type of wires you’ll be replacing, and how much wire you’d like to replace. To help you decide, here are some factors to consider.

Home Size

A rewiring project can cost from $2 to $4 per square foot, including labor and materials. As a rule of thumb, for a 2,000-square-foot house, the cost can range from $4,000 to $8,000

Scope of The Project

Depending on whether you are upgrading electrical panels, rewiring parts of your home, or the entire house, there is a wide range of costs. Also, the types of wiring and cables used will influence the project costs.


Cables made from nonmetallic materials, such as NM, cost about $0.40 to $0.80 per linear foot. Subterranean or moist spaces require underground feeder cable (UF), which is the same as NM cable but costs $0.50 to $0.75 per linear foot.

Labor & Permits

To rewire your home, you will need to hire a licensed electrician. On average, the time required for wiring a 100-square-foot room is one hour of work.


The cost to hire a licensed electrician varies according to every company and depends on their expertise.


Your current system and location will determine how and where you need permits and inspections. Doing these is often necessary to ensure your wiring is up to contemporary standards. It will ensure your family’s safety for decades to come. 


Depending on the complexity of your electrical system, permits typically cost between $10 and $500.


The cost of rewiring a home greatly depends on how much access an electrician has to the old wiring before replacing it.


Old homes with plaster walls can be difficult to wire. A second contractor will need to open the borders and close them again after the electrician finishes writing.

Type of System & Material

Modern appliances and technology require more electricity than 60 amps in older homes. Rewiring typically requires 200-amp systems that cost between $1,300 and $3,000. The national average cost of rewiring a whole house is about $1,402 (including upgrading the electrical system to 200 amps).

The Cost to Rewire a House by Wire Type

Depending on the wires and cables you’ll need, the cost of rewiring a house will also vary. Your electrician may recommend the following lines according to your specific needs.

UF Cable

Underground feeder cables (UF) run underground or through damp areas. As with NM cables, they have additional protective coverings on the outside. A linear foot of wiring with UF cables will cost you between $0.50 and $0.75.

NM Cable

Nonmetallic cables, or NM cables, are standard for homes. An NM cable consists of a hot conductor (the one that carries current), a neutral conductor, and a ground conductor. An outer plastic sheath protects the three wires. Rewiring NM cables costs between $0.40 and $0.80 per linear foot.


Usually, THHN and THWN wires are color-coded with plastic covers. THHN wire is often used in appliances because it is thermoplastic and highly heat-resistant. A THWN is similar to a THHN but is more water-resistant. Rewiring with THHN or THWN costs approximately $0.80 to $1.60 per linear foot.

Frequently Asked Questions

A house rewire may last for 20 years or more, sometimes as long as 40 years, but eventually, the insulation on the cables will break down, and you will need to rewire the house.
