Electrical Wiring Cost by Type of Installation
The cost to redo electrical in a house depends largely on the linear feet of wire to pull and how labor-intensive the job is. Fishing electrical wires and cables through walls and connecting components to panels, switches, and outlets are all critical tasks that require precision.
However, wiring during new construction is more manageable due to open walls – expediting the workflow and reducing expenses.
You should do the rewiring if your home’s electrical wiring is outdated and cannot be used safely. Rewiring an existing house requires more effort and time since the old wires should be removed entirely (or bypassed) before running any new electrical wiring.
Cost of Rewiring a House Per Square Foot
The electrical rewiring cost, on average, is about $6 to $12 per square foot, including removing older wiring systems and installing new wires. In some cases where access is not difficult, the walls may stay intact, and only small holes need to be cut for entry and exit points.
However, if the electrical rewire of a house cost requires partial wall destruction, repair costs, labor costs, and existing expenses are likely.
Rewiring a 2,000 square feet house can cost anywhere from $12,000 to $24,000, depending on the accessibility of its wiring.
Similarly, with smaller homes such as 1,000 square feet, rewiring may be more expensive due to drywall removal and wood drilling needed for the electrical contractors to access wires. Drywall repairs only add to the rewiring expense.
Less accessible places, like attics and crawl spaces, increase the average cost of 1,250 square feet of home rewiring up to an estimated range of between $7500-15,000.
Average Cost of Rewiring a Home by Number of Bedrooms
Electrical rewiring prices differ significantly depending on the size of your living space. Generally, home size by bedroom typically are:
|Number of Rooms||Size||Estimated Cost|

|Two Bedroom||1,000 to 1,300 SF||$3,900 to $9,100|
|Three Bedroom||1,500 to 2,000 SF||$4,500 to $14,000|
|Four Bedroom||2,000 to 2,500 SF||$6,000 to $17,500|
- One-bedroom dwellings are in the range of 800 to 1,000 square feet
- Two bedrooms are around 1,000 to 1,200 square feet
- Three bedrooms usually hover between 1,500 and 2,000 square feet
- Four-bedroom residences tend toward an average of 2,000 up to 2,500 square feet
Bear in mind that these measurements may alter from location to location.
Cost to Rewire a Kitchen
Electrical rewiring is critical to any kitchen renovation, providing your home with up-to-date safety requirements and efficient outlets. This crucial step should not be overlooked for older homes, especially those needing bathroom renovations.
The cost to update electrical for appliances depends on various factors, including the wire size and length to run the wire. Large gauge wire for a 50-amp stove circuit will cost more than a 120-volt circuit for smaller appliances like dishwashers and refrigerators, requiring fewer amps. However, local labor costs also play a key role.
The average price for kitchen rewiring can be anywhere from $620 to an eye-popping $4,000 or more – with the typical cost falling between $1,500 and $2,855.
Cost varies depending on the additional circuits, materials, and codes needed (such as AFCI circuit protection and GFCI outlets by National Electrical Code).
According to current NEC guidelines, kitchen circuits require both AFCI and GFCI protection, so many qualified electricians opt for installing CAFCI breakers that provide both. All countertop outlets need GFCI protection, and appliances like dishwashers and refrigerators now require dedicated circuits.
Cost to Rewire a Bathroom
Rewiring a bathroom can be costly, ranging from an affordable $240 to an expensive $3,710. The size of the room and necessary labor are determining factors that influence the price.
Bathrooms usually range in area from 40 sq. ft. to 310 sq.ft., while materials needed for installation and electrical system complexity also play their part in pricing estimates. Nonetheless, remodeling your bathroom without opening walls could save you money, making this ideal scenario more economical overall!
While electric radiant floor heating and heated towel racks might seem like extra luxuries, installing them in your bathroom can increase the project’s total cost. Additionally, according to NEC standards, every outlet in a bathroom has ground-fault circuit interrupters (GFCI) for maximum protection and safety.
Bathrooms often require more outlets and light fixtures than other rooms, which may require additional wiring circuits and bring up the overall expense ranging from $1,000 to over $3,000, depending on multiple factors. Though rewiring an entire bathroom is quite an extensive investment for your home’s security and usability, it will be worth it in the end!
Cost to Rewire a Laundry Room
Wiring a laundry room can range from $325 to approximately $1200, depending on the size (55-100 sq.ft.) and what you plan to include in your project.
For example, if it’s an electric dryer that needs a dedicated 240-volt circuit unless you have a gas dryer. Lights, receptacles, and clothes washers now require GFCI and AFCI protection.
Cost to Rewire a Bedroom
Rewiring a bedroom can cost anywhere from $790 to an astonishing $3,705. American bedrooms usually measure 130 sq ft., and master suites around 310 square feet; therefore, larger rooms are more expensive. Make sure not to confuse the area of any bathrooms with that of your room when calculating prices!
NEC guidelines can guide placement and spacing for older homeowners seeking to add extra outlets. However, suppose the local electrician needs to open walls to replace old wiring as part of a retrofit job. In that case, this will incur higher costs than starting with a room already opened up during an extensive remodel.
Cost to Rewire a Living Room
Sprucing up a living room can cost anywhere from $990 to $3,600 depending on the dimensions, typically between 165 and 300 sq. ft. Although bedrooms and living rooms may have similar electrical wiring requirements, GFCI outlets are only necessary near water sources, like a mini-bar.
Overall expenses will likely increase based on your creativity for illuminating artwork or crafting an inviting atmosphere!
Homeowners often opt for more eye-catching elements, like chandeliers, if their ceiling is vaulted to give their living room a luxurious feel. Of course, the rewiring costs can quickly increase when an electrician needs to fish wiring for new outlets and wall sconces and install fans. NEC now requires AFCI protection on all living room circuits.
Cost to Rewire a Garage
The price of rewiring a garage can differ drastically depending on the size and complexity of the space, with prices ranging from $1,440 to an impressive $9,600.
Generally speaking, this cost is applicable for garages between 240 sq. ft. and 800 sq. ft. Suppose you only need basic wiring or additional outlets for power tools. In that case, your costs are likely lower than those requiring more intricate finish work or updated lighting features in the project plan.
According to the National Electric Code (NEC), you should replace all wires and switches with GFCI outlets if you get a rewiring job. Wire installation for fixtures or appliances in the garage is included in most services. Yet, other electrical upgrades, such as electric car chargers, may come at an additional charge due to their more complex wiring requirements.
Cost to Rewire a Basement
The cost of renovating a basement can vary from thrifty to lavish, depending on the size (generally 500 sq. ft. to 1,500 sq. ft.) and the required modern wiring upgrades. When upgrading wiring in your basement, consider factors such as dimensions and design of the area, the intricacy of the electrical system setup needed, materials used for repairs/replacement, and labor expenses too!
According to the National Electric Code (NEC), GFCI outlets are in all basements, yet there is no minimum height requirement. The price of rewiring a basement might vary due to additional lighting fixtures or large appliances. However, you may pay less overall if it’s already been rough-wired and finished during new construction.
Outfitting a basement with the necessary outlets and light fixtures may necessitate additional circuits to accommodate its power requirements, resulting in higher expenses. Budgeting between $1,500 – $4,000 (or more) for rewiring your basement is recommended as an average cost—this figure can fluctuate depending on various elements.
Cost to Rewire a Small House
Although rewiring a modest home may be more affordable than larger residences due to fewer wiring and shorter completion time, the cost still varies depending on factors such as the electrical system’s complexity and local labor costs. It would be wise to request quotes from multiple electricians to obtain a precise price tag.
A one-bedroom cottage can be wired at a reasonable cost of around $4,800. A two-bedroom bungalow can be rewired for about $6,000. A three-bedroom ranch can be rewired for $8,000. A four-bedroom split-level house can be rewired for $12,000.
Cost to Rewire a 3-Bedroom House
When setting a budget for rewiring your 3-bedroom house, several elements must be considered. You should consider elements such as your residence’s size and design, its electrical system’s intricacy, regional labor costs, and material expenses.
Generally, larger homes demand more wiring, so they cost more than smaller ones. To get an exact quote for this project, we strongly advise getting multiple quotations from reliable electricians before making any conclusions.
Cost to Rewire a 2-Story House
Rewiring a two-story larger home is undeniably more complex and intricate than rewiring a single-story residence. This means additional wiring and expert electricians are needed to access those hard-to-reach locations.
With this in mind, the price of two-story rewiring may be higher compared to one-story homes. These costs vary depending on the house size and layout, the complexity of its electrical system, local material prices, and labor costs.
Cost to Rewire a Ranch-Style House
Rewiring a ranch-style house may be more expensive than smaller homes due to its size, the number of outlets, light fixtures, etc.

Rewiring a mobile home can be quite costly – the price tag for this project varies between $5,540 and $11,090. The size of your dwelling is key since US mobile homes are typically between 925 and 1,440 square feet.
There’s an additional factor to remember; similar to traditional houses that require new outlets, switches, and circuit panels, so do mobile homes! Much like conventional stick dwellings – the more complicated it gets for wires to reach their destination–the more expensive it becomes!
If your mobile home has accessible electrical wires, rewiring it can be much more cost-effective than in larger models where they may be harder to reach. Electricians follow National Electrical Code standards when hooking up a new wiring system for the mobile house, guaranteeing safety and workmanship throughout the project.
Labor Cost for Electrical Work
It is essential to account for the labor when planning a home wiring project, such as replacing an electrical panel or rewiring the entire house. The certified electrician will be responsible for pinpointing where lights, outlets, and switches should go and assessing if an upgrade of your circuit panel is necessary.
They can also guide you in selecting light fixtures that work best with your space if desired. Wiring can be installed all at once during new construction projects so that there are no electrical issues covering every outlet, switch, and lamp within the home.
Holes may be cut into walls during a rewiring project to access and eliminate the old wires. You can access these through attics, crawl spaces, or other simple points of entry; however, you may need to create wall openings.
If such an action is needed, additional fees for restoring the appearance of said walls will also apply. Securing an electrical permit and enlisting a professional electrician is essential when installing or replacing a circuit panel to guarantee that safety protocols are met.
Electricians typically bill between $40-$120 hourly to rewire a home. The overall cost of such projects depends on either all-inclusive rates covering each area individually or combining labor and material costs across different regions.
The labor cost to rewire a house can constitute a considerable share of the total cost, ranging from 30% to 50%. Before commencing your project, certain electricians may ask for payment to estimate its cost. If you proceed with their services, this amount might be credited toward the final bill.
Electrical Inspection Cost
Whether buying an older house or renovating one, it is always beneficial to have a professional electrical inspection done. Most cities require this before issuing permits for renovations, and such an examination will provide extra protection against any problems caused by old wiring.
In most areas, a local building inspector will inspect all aspects of your electrical wiring system, including the circuit numbers and types, GFCI/AFCI protection devices, cable anchoring methods, and more, so that you can rest assured that your home’s electricity is secure and current.
When assessing your home’s wiring and current capacity, the only qualified party is a licensed electrical contractor or C10 contractor. Depending on geographical location, size of the house, and how accessible it is for inspection, this assessment can cost between $250 to $550.
For rewiring work, you’ll likely need a permit from your local building department to ensure everything has been done safely.
Materials and Types of Electrical Wiring
Homeowners should thoroughly understand the various types of electrical wiring available. Utilizing the correct type and amount in every situation can help you avoid future problems, plus save you money in the long haul! From conduit to armored cable wiring, we’ll provide insight into different varieties of electrical wiring and their widespread uses for residential applications.
Copper wiring is a go-to choice for residential electrical systems due to its durability, dependability, and affordability. It consists of multiple strands of copper wire intertwined to form an electrically conductive wire.
Copper wiring is ideal for transmitting electricity efficiently over long distances, especially in large homes with multiple rooms. However, it’s important to remember that copper corrodes more quickly than other metals and should be inspected regularly and replaced as necessary.
Homeowners often choose aluminum wiring for their electrical systems due to its lower cost than copper. Solid strand aluminum wiring is no longer because of safety hazards. Solid-strand aluminum expands as it heats, which can cause loose connections as it cools.
Multi-strand aluminum wiring is still in use today because it’s proven safe. Multi-strand aluminum wire is only used for current wiring appliances like electric stoves and main electrical feeder cables.
Multi-strand aluminum is about twice the size of multi-strand copper. However, multi-strand aluminum is more flexible, lighter, easier to work with, and more cost-effective than copper.
Also known as BX cable, armored cable consists of an armored outer layer that protects the insulated wires from physical damage. The outer layer comes in metal (usually steel) or plastic-coated aluminum, providing reliable protection against abrasion and other external elements.
Armored cables are often used for commercial installations where flexibility is needed, such as in ceilings, crawl spaces, and areas with high temperatures or moisture levels. It is more expensive than Romex wiring but offers better protection from physical damage and harsh environmental conditions.
Non-Metallic Wiring / Romex Wire
Homeowners often opt for non-metallic sheathed cables (NM) due to their affordability and ease of installation. The NM wiring consists of two insulated wires – usually black and white – with a bare copper ground encased in an outer insulation jacket for durability.
Romex wire is the most commonly used type of electrical wiring in residential homes, and building codes often require it to ensure safety. Romex can easily power lighting fixtures, ceiling fans, receptacles, switches, and other household appliances safely throughout any home.
Fiber Optic Cables
Fiber optic cables are becoming increasingly popular in modern homes due to their superior speed and security capabilities compared to traditional electrical wiring systems. Fiber optic cables use light signals instead of electricity to transmit data from point A to point B, resulting in much faster transmission speeds than traditional copper or aluminum wires can provide.
Fiber optic cables are essential for executing long-distance, high-functioning data networking operations. Furthermore, these technologies are commonly leveraged to offer telecommunication services such as internet access, TV, and telephone services.
Unshielded Twisted Pair Cable:
UTP cable, Unshielded Twisted Pair cable, is a type of cable composed of multiple pairs of twisted copper wires covered in plastic insulation jackets designed to reduce crosstalk interference between each pair while still providing ample signal transmission strength over long distances without loss or degradation.
UTP cable is often used for networking purposes, such as connecting computers to routers or modems or running network cables through walls within office buildings or homes.
Stranded vs Solid Wire Cost
Two types of wiring are available in residential homes: stranded and solid. Solid copper wiring is the best choice for smaller gauge wire sizes. Stranded wiring is used in larger circuits where more power is necessary. The smaller strands of copper or aluminum make it flexible and easier to bend and install.
All solid wiring now is copper wiring. Solid aluminum wiring heats and expands, allowing loose connections as the wiring cools down. Stranded aluminum is generally preferred over copper in larger circuits because the wiring is lightweight and cheaper than stranded copper wiring.
Signs a House Needs Rewiring?
Electrical wiring is important in keeping your home safe and up to code. According to Clover Electric, homes with old wiring can drastically increase your chances of residential fires. But how can you tell if the wiring in your home needs to be replaced or updated?
Here are some signs indicating it’s time for some rewiring.

It could also indicate that the electrical system is overloaded and needs more capacity. In either case, it’s best to have a professional come out and look at it immediately.
Frequent Circuit Breaker Trips
Do you find yourself constantly having to reset circuit breakers? If so, this indicates that your electrical system may not be able to handle the amount of current being drawn from it. The electrical surges are overloading circuits and can cause serious damage if they aren’t addressed immediately, so make sure you call an electrician immediately if you’re experiencing these wiring issues.
Outlets are Hot to the Touch
If you ever feel that an outlet in your home is warm or hot to the touch, don’t ignore it! This could indicate frayed insulation or a loose connection inside the outlet, which can cause electrical fires. Have an electrician inspect any outlets that seem too hot and replace them if necessary.
Lights Flicker or Dim Unexpectedly
Have you ever noticed that lights in your house flicker or dim unexpectedly? If so, this could indicate overloaded circuits or faulty wiring. The wiring behind walls and ceilings can wear out over time due to frequent fluctuations in voltage and current drawn from appliances. An electrician can inspect these circuits and repair any damaged wires as needed.
Old Ungrounded Wiring is Present
Updating the electrical in an old house will cost more if trenching through plaster walls. Some opt to run wiring in conduit outside the plaster wall to avoid the additional expense of repairing plaster walls and ceilings.
If you have exposed ceiling joists in your attic or basement, look around for outdated wiring, such as knob-and-tube (K&T), aluminum, or cloth-covered wiring.
These types of wiring were widely used in homes built before World War II but are no longer up to code requirements and pose a risk of house fires if they aren’t replaced with modern copper wiring. Have an electrician inspect all exposed wiring in your home and replace outdated materials with newer ones.
Cost of Rewiring an Old House
Updating the electrical wiring in old homes that cannot handle modern devices and appliances is essential for your family’s safety. Aluminum or cloth-wrapped wires can be a fire hazard if left unchanged; therefore, replacing them with new materials is critical for ensuring your home remains secure.
Plaster walls in old homes only complicate rewiring. Some homeowners abandon outdated wiring and run new wiring in conduit outside the plaster walls rather than trenching through plaster which is difficult to repair.
The price of renovating knob-and-tube wiring is usually comparable to the expense of converting aluminum wiring to copper. It depends on how challenging the project is, the availability and cost of modern materials and the number of components that need altering. Rewiring a house’s electrical systems can range from $6 to $12 for every square foot.
Investing in an electrician’s assessment and proposal—which usually costs between $100 and $200, regardless of whether or not you plan to employ them for the project—can prove beneficial. Suppose you do decide to bring in the same professional.
You will deduct expenses incurred from replacing switches and lights, upgrading an electric service panel, or removing archaic materials from your payment total. Please note that most light fixtures require new wiring; this is included in their overall cost but not factored into their price tags!
When selecting their light fixtures for the rewiring project, homeowners should be sure to do so before beginning to secure an accurate estimate of time and costs. This estimation also includes additional fees for installing new fixtures and all other associated tasks. Once these decisions are made, the electrician can finish up everything during the final phase of the rewiring installation!
Cost to Rewire a House with Knob and Tube Wiring
Replacing knob and tube wiring is crucial for homeowners because it fails construction codes and isn’t safe. The expense of this project depends on factors like the size, structure, and electricity complexity of your house, plus local materials & labor costs.

Cost to Rewire a House with Aluminum Wiring
If your home is wired with aluminum, know that it should be replaced quickly to meet current safety codes and regulations. Aluminum wiring replacement can cost more than usual due to the additional materials required and higher labor costs for removing old wires and installing new ones.
The cost of replacing electrical wiring can be avoided with copper-to-aluminum connectors.
Some retrofit options include copper-to-aluminum connectors that can pigtail the branch wiring and connect the copper ends to the breakers and each outlet, switch, and fixture. While this option isn’t as good as rewiring, it is safer than aluminum alone.
Cost to Rewire a House From Aluminum to Copper
Structures built or rewired before 1960 often feature aluminum wiring, which was favored for its affordability and lightness. However, when exposed to heat, it can expand and melt nearby areas; additionally, corrosion will weaken this material more quickly than copper wires, which are heavier but stronger.
Therefore, utilizing aluminum wiring is hazardous because upgrading your amps to handle today’s higher power outputs drastically increases the risk of fire hazards.
According to CPSC research, homes with aluminum wiring are 55 times more vulnerable to house fires than those wired with copper. In other words: precision matters!
Outfitting aluminum wiring with copper costs approximately $6 to $12 per square foot, including the materials and labor of fitting new circuitry, outlets, switches, or other cabling. Additionally, any disposal fees for obsolete equipment must be accounted for.
Cost to Rewire a House with Old Electrical Panel
Replacing an aging electrical service panel is essential for safety and keeping up with modern living. The cost of such a replacement can vary depending on your home’s size and structure, the complexity of the electricity system, as well as local material & labor costs.
National Electrical Code Guidelines
National Fire Protection Association (NFPA) sets National Electrical Code (NEC) guidelines.
To ensure the security of your home, it is essential to comply with NEC standards when rewiring. The NEC is updated every three years and follows best practices in electrical engineering and recent technology advancements.
Specific regulations detailed by the NEC may include requirements for wiring type, circuit protection, electrical panel circuits, maximum load capacity per circuit, and more – so be sure to familiarize yourself before starting any project!
The NEC not only mandates standards for electrical devices such as receptacles and outlets but also recommends the utilization of GFCIs and AFCIs to ensure against fire or shock risks. However, while the NEC sets guidelines, local municipalities set which standards they adopt and enforce.
Although NEC codes are not exhaustive, it is wise to seek the counsel of a seasoned electrician who can ensure your electrical system conforms with these standards and any other laws. To protect and observe the NEC regulations, you should apply for an electrical permit before rewiring and arrange an inspection afterward.
Following the NEC codes are paramount to preventing electrical fires and safeguarding against other hazards. Professional electricians who understand these rules should be sought to offer a secure, compliant home’s electrical system.
Such practical applications of the code include installing GFCI outlets near water sources (ex: bathrooms and kitchens), placing switches near each room entrance, and installing additional wall outlets. On top of this, light fixtures should always be spaced & put on according to the guidelines for maximum safety measures!
Cost to Wire Appliances
An electrician can do more than wiring- from installing modern appliances and alarm systems to installing new outlets.
