Rewiring a house costs, on average, between $6 and $10 per square foot. Rewiring involves the removal of all wires and their replacement with new ones. It's a common project for older homes, particularly those built before 1960. Pulling out old wires from walls, crawl spaces, ceilings or attics may require making small openings. If access is particularly problematic, larger areas of drywall may require removal and replacement, increasing the cost.

House Rewiring Prices by Wire Material

There are more than twenty electrical cable varieties, but not every home uses all of them. There are nine types common to most homes, and these vary in price from $0.10 to $2.00 per linear foot. Note that this is the cost of the cable only and doesn't account for labor or additional supplies and components.

Type of CableAverage Cost Range per Linear Foot (Materials Only)
Multi-conductor$0.20 – $0.35
Shielded twisted pair$0.20 – $0.35
Coaxial cable$0.25 – $0.35

Underground feeder$0.50 – $0.70
Twin-lead$0.60 – $0.80
Non-metallic sheathed$0.60 – $0.80

House Rewiring Installation Cost

Hiring an electrician costs between $40 and $125 per hour, so you can see that labor is where most of your budget goes for a rewiring project. Also note that rewiring is a big, time-consuming job, and rewiring a whole house can take up to a week. A single room, depending on the size, takes up to two days.

House Rewiring Cost by Square Foot

Most electricians charge for rewiring by the square foot, including all materials (cables, drywall repair, connectors and so on) and labor. For rewiring, expect to pay between $6 and $10 per square foot, all-in. Here are some typical room and property sizes and the average cost range for rewiring:

Square FootageAverage Cost All-In
800 sq. ft.$4,800 – $8,000
1,000 sq. ft.$6,000 – $10,000
1,300 sq. ft.$7,800 – $13,000
1,600 sq. ft.$9,600 – $16,000
2,000 sq. ft.$12,000 – $20,000
2,500 sq. ft.$15,000 – $25,000

Cost to Rewire a House by Room

When rewiring is advisable but not immediately essential, some homeowners choose to wait until they are remodeling, then rewire the room(s) being remodeled. If the remodel involves opening walls, the costs of rewiring fall close to that of wiring a new property, between $3 and $5 per square foot.

If your budget doesn't stretch to rewiring the whole house at once, you can also choose to do the most essential rooms one at a time, as your budget allows. Prices for rewiring single rooms vary a lot based on ease and accessibility and room size.

Cost to Rewire a Kitchen

Nationally, the average cost to rewire a kitchen measuring 151 square feet falls between $450 and $1,500. The price includes removing old wires, installing new ones, and updating or replacing wiring for fixtures and appliances.

For an exact quote, contact a local electrician. The cost of copper wire has increased, and kitchen appliances (stoves, cooktops, and ovens) normally need larger copper wire compared to other rooms.

“Rewiring a house can be expensive, but the cost is well worth the benefit, safety, and peace of mind of such an upgrade,” says Salvatore Cutrona, Expert Review Board member and licensed electrician.

Cost to Rewire a Garage

An average-sized garage costs $1,150 to $2,360 to rewire. The cost includes replacing wires, outlets, and switches. If your garage interior is unfinished, you'll pay toward the lower end of this range, as it's easier and less time-consuming to replace wires in unfinished spaces.

Cost to Rewire a Room

An average-sized room is around 481 square feet. Based on this, the cost to rewire an average room falls between $1,445 and $4,810, all-in. If you're already remodeling your living space, for example, and the walls are already at least partly open to accommodate the renovation, your costs are likely to be at the lower end of this range, even if you have additional outlets and switches added.

Factors That Influence the Cost to Rewire a House

Aside from the standard costs of removing old wiring and installing new and how big and easy to access the space is, many other factors influence the total project cost of rewiring a house.

Bundling Additional Work

If you have other electrical work that needs completing, such as adding new outlets, running electricity to a shed or exterior workshop, setting up an alarm system, or wiring up appliances, it's worth asking the electrician to add those to the quote, too. Because most electricians have a minimum callout charge, you can often save money by bundling work.

Upgrading the Electrical Panel

If the electrician finds that the existing electrical panel doesn't have a high enough amperage to meet your current demands for electricity, you'll need to upgrade it. The cost to upgrade an electrical panel to a higher amperage is around $2,500.

Additional Cleanup

While many electrical contractors clean up after they've finished the job, some don't, particularly if they've made a lot of mess because of removing drywall. Some don't include this as part of their service and require you to hire a local cleaning crew. Hiring a cleaning crew costs up to $500, depending on the extent of the work they need to complete.

Extra Remedial Work

If the pro finds safety hazards or other issues that fall out of the scope of their current contract during the course of their work, you'll need to revise the existing contract or sign a new one and pay for the extra remedial work.

DIY vs. Hiring a Rewiring Pro

Rewiring a house really isn't a DIY job. It's a big task that requires specific skills, tools, and experience. Electrical wiring safety is a serious matter. And, if you get it wrong, it can be deadly. You really need a qualified, suitably licensed electrician to rewire a house or even a single room. Aside from the safety and difficulty aspects, you'll also need to apply for permits, submit detailed electrical diagrams, and pass an electrical inspection once the work is completed. For all of these reasons, the only real option is to hire an electrician.

FAQs About Rewiring a House

How do I know if I need to rewire my house?

There are many subtle and not-so-subtle signs that you might need to rewire your house. These include:

  • Lots of blown fuses and tripped circuit breakers

  • Lights that flicker and dim

  • Hot or discolored outlet plates, switches, plugs or cords

  • You're having to change lightbulbs a lot

  • Buzzing or sizzling sounds from outlets and light fixtures

  • An inexplicable burning smell

  • Arcs or even sparks from an outlet when you plug something in

  • Loose outlets

  • Getting an electric shock when you plug something into an outlet or touch a cord that's plugged in.

How long does wiring in a house last?

In ideal conditions, wiring in a house lasts 50 to 70 years, but many factors can shorten this timeframe, such as moisture damage and unsustainable demand.

Does a 1960s house need rewiring?

Yes, a 1960s house most likely needs rewiring if it hasn't already been done. That's because it probably still has knob-and-tube wiring, which often has flammable fiber casings that pose a significant fire risk. If this is the case, you'll also have to upgrade the circuit panel, outlets and light switches, and fixtures too.
