Cost to Rewire a House in 2026: Complete Price Guide

Rewiring a house typically costs $10,000 to $30,000 in 2026 for a substantial whole-house project, with a national planning range of approximately $1,300 to $30,000 when smaller or partial rewiring jobs are included. The final price depends on the home's square footage, age, existing wiring, number of circuits, electrical panel condition, and how easily electricians can access walls, ceilings, and floors. A small home with accessible wiring may cost substantially less than a large, occupied house that requires extensive demolition and restoration.

Rewiring replaces some or all of a home's existing electrical conductors with new wiring and associated components. The project may also include updated outlets, switches, grounding, circuit protection, and electrical panel work when needed. For homeowners planning a renovation or addressing unsafe electrical conditions, understanding the cost to rewire a house helps establish a realistic budget before work begins.

These figures are national planning estimates, not guaranteed contractor prices. A written inspection and project-specific estimate are necessary to determine the actual cost.

Cost to rewire a house cost at a glance

Cost factor	Estimated price
Overall project range	$1,300–$30,000
Typical whole-house rewiring	$10,000–$30,000
National planning average	About $20,000
Small home or limited rewiring	$1,300–$8,000
Partial rewiring	$1,500–$10,000
Extensive older-home rewiring	$15,000–$30,000+
House rewire cost per square foot	$5–$17
Electrical panel upgrade, if needed	$1,300–$4,000
Drywall repair after rewiring	$200–$1,500+
Permit and inspection allowance	$100–$500+

The overall range includes projects of different sizes and scopes. The typical whole-house range is more useful when budgeting to replace wiring throughout an average residential property. Large houses, historic properties, difficult access, and major electrical upgrades can push the total above $30,000.

The national planning average of about $20,000 is a budgeting reference rather than a prediction for every home. A limited repair or partial rewire may cost much less, while a complete electrical renovation can cost considerably more.

Whole-house rewiring cost by home size

Home size is one of the most important factors affecting the full house rewiring cost. Larger homes generally have more outlets, switches, lighting circuits, appliances, and wiring runs. However, square footage alone does not determine the final bill.

For planning purposes, a broad allowance of $5 to $17 per square foot can help estimate the cost of rewiring a house. The following estimates apply that range to different home sizes.

Home size	Low estimate	High estimate
800 sq. ft.	$4,000	$13,600
1,000 sq. ft.	$5,000	$17,000
1,200 sq. ft.	$6,000	$20,400
1,500 sq. ft.	$7,500	$25,500
2,000 sq. ft.	$10,000	$34,000
2,500 sq. ft.	$12,500	$42,500
3,000 sq. ft.	$15,000	$51,000

These figures are broad estimates based on the per-square-foot allowance, not fixed national prices. A 2,000-square-foot home may fall within the typical $10,000 to $30,000 range, but a complicated project could exceed it. Similarly, an accessible, partially finished home may cost less than a fully occupied property of the same size.

The upper calculations in the table exceed the standard $30,000 planning range because difficult or unusually extensive projects can fall outside typical budgets. For large homes, obtain a detailed estimate instead of assuming that the lowest per-square-foot figure will apply.

Why square footage is only a starting point

Two homes with identical floor areas can have very different electrical requirements. One may have an open basement, accessible attic, and modern panel, while the other has plaster walls, several finished floors, and old wiring hidden inside inaccessible cavities.

The number of circuits also matters. A house with electric cooking, a clothes dryer, central air conditioning, electric heating, a workshop, and an electric vehicle charger may need more electrical capacity and dedicated circuits than a home with fewer high-demand appliances.

A contractor should evaluate the existing installation, planned electrical loads, wiring routes, and condition of the service equipment before providing a firm price.

Cost by project type

Not every home needs every wire replaced. The appropriate scope depends on the condition of the existing installation, the reason for the work, and whether the project is part of a larger renovation.

Project type	Estimated cost
Small, localized wiring replacement	$1,300–$3,000
Rewiring one room	$500–$2,000
Rewiring several rooms	$2,000–$8,000
Partial house rewiring	$1,500–$10,000
Complete rewiring of a small home	$5,000–$15,000
Complete rewiring of a typical home	$10,000–$30,000
Extensive rewiring of an older or large home	$20,000–$40,000+

These categories overlap because contractors define project scope differently. A room with accessible wiring and a few circuits can be relatively straightforward, while a room requiring new circuits, extensive wall openings, and finished-surface restoration may cost more.

A partial rewire is appropriate when an electrician can safely isolate the affected areas and confirm that the remaining wiring is suitable for continued use. Replacing a few damaged sections without evaluating the wider system can leave underlying hazards unresolved.

A complete rewire generally involves replacing the wiring throughout the agreed scope of the property. Depending on the home, the electrician may also replace receptacles, switches, junction boxes, grounding conductors, and other components.

Cost by wiring material and existing system

The type of existing wiring can affect the labor, preparation, and scope of a rewiring project. In many cases, the objective is to replace outdated or unsafe wiring with modern copper conductors and appropriate protective devices.

Existing wiring or material	Estimated project cost
Standard copper wiring replacement	$10,000–$30,000
Knob-and-tube wiring replacement	$8,000–$30,000+
Aluminum branch-circuit wiring replacement	$5,000–$20,000+
Replacement of damaged or deteriorated wiring	$1,300–$10,000+
New wiring in an accessible renovation	$5,000–$15,000
Rewiring with extensive plaster or masonry work	$15,000–$35,000+

These are broad planning allowances, not separate national averages for each wiring material. The amount of wiring involved, the condition of the existing system, and the need for wall repairs can matter more than the conductor material itself.

Knob and tube replacement cost

Knob-and-tube wiring was used in many older homes and typically consists of individual conductors supported by ceramic knobs and passing through ceramic tubes. Some installations remain in service, but age, modifications, insulation contact, deteriorated components, and missing grounding can create safety concerns.

The knob and tube replacement cost can range from roughly $8,000 to $30,000 or more when a substantial portion of a house needs rewiring. Smaller, accessible sections may cost less, while a complete replacement in a large historic property can cost considerably more.

One important complication is that older homes may have hidden wiring behind plaster walls, original woodwork, or decorative ceilings. Removing the old conductors and routing new cable can require careful access and restoration.

An electrician should inspect the wiring and determine whether it can remain safely in service or needs replacement. Homeowners should not assume that adding modern insulation over or around old wiring is acceptable. The suitability of insulation contact depends on the wiring system, its condition, and applicable electrical requirements.

Aluminum wiring replacement cost

Some homes built during periods when copper was expensive used aluminum conductors for branch circuits. Aluminum wiring is not automatically defective, but certain older installations and their connections can present risks if components are incompatible, loose, damaged, or improperly installed.

The aluminum wiring replacement cost may range from approximately $5,000 to $20,000 or more for substantial projects. Replacing all affected branch-circuit wiring generally costs more than addressing a limited number of connections or circuits.

A qualified electrician can evaluate the wiring, identify compatible devices and connectors, and determine whether full replacement or an approved remediation method is appropriate. Any connection work must use components specifically listed for the application and installed according to their instructions.

Modern copper wiring

Copper is commonly used for modern residential branch circuits because it is widely supported by electrical equipment and installation practices. The correct wire gauge and insulation type depend on the circuit's intended use, amperage, installation conditions, and local code requirements.

The cost of copper wiring itself is only part of the overall project. Labor, access, boxes, protective devices, circuit routing, and restoration frequently make up a substantial share of the final price.

House rewire cost per square foot

A common planning rate for a whole-house project is $5 to $17 per square foot. This rate is useful for comparing preliminary estimates, but it should not replace a detailed contractor quote.

Home size	At $5 per sq. ft.	At $10 per sq. ft.	At $17 per sq. ft.
1,000 sq. ft.	$5,000	$10,000	$17,000
1,500 sq. ft.	$7,500	$15,000	$25,500
2,000 sq. ft.	$10,000	$20,000	$34,000
2,500 sq. ft.	$12,500	$25,000	$42,500
3,000 sq. ft.	$15,000	$30,000	$51,000

The low end is more likely when access is straightforward, the layout is uncomplicated, and the project requires limited restoration. The high end may apply when the house has multiple stories, inaccessible wiring, extensive finish work, or substantial changes to circuits and electrical equipment.

A per-square-foot quote also needs a clear definition of what is included. One electrician may include outlets, switches, and panel work, while another may price these separately.

Cost per linear foot

Linear-foot pricing is less useful for estimating a complete house rewire because electrical installations involve different wire sizes, circuit types, access conditions, and termination requirements.

For an initial budget, some homeowners may see rough allowances of approximately $3 to $10 per linear foot of straightforward wiring installation. This is an illustrative planning figure rather than a standardized national rate. It should not be confused with the cost of every foot of cable in a finished-home rewiring project.

Ask whether any quoted linear-foot rate includes labor, cable, boxes, connections, testing, and opening or repairing walls. A rate covering cable installation alone will not represent the complete project cost.

What moves the price

Several factors determine whether a rewire falls near the lower or upper end of the national range.

Age and condition of the house

Older homes may contain brittle insulation, ungrounded circuits, knob-and-tube wiring, aluminum branch circuits, or undocumented modifications. These conditions can make the work more time-consuming and may require additional safety measures.

A recently renovated house with accessible, serviceable wiring may need only targeted improvements. A home with decades of alterations may require extensive tracing and testing before the electrician can determine the safest replacement plan.

Access to wiring

Accessible basements, attics, crawl spaces, and unfinished walls can reduce labor. Electricians can often route cables through these spaces without opening every wall.

Finished plaster, tile, stone, and decorative wood surfaces increase the difficulty. Homes with concrete walls or masonry construction can be particularly challenging because conventional cable routing may require specialized methods or surface-mounted raceways.

Number of outlets and circuits

More outlets, switches, lighting points, and dedicated appliance circuits generally mean more materials and labor. The final price also depends on whether existing locations can be reused or the homeowner wants to add new electrical points.

Dedicated circuits may be necessary for appliances with substantial electrical loads. Adding a kitchen, workshop, home office, or outdoor entertainment area during a rewire can increase the project's scope.

Electrical panel and service capacity

A house may need a new or upgraded panel if the existing equipment is damaged, obsolete, lacks sufficient spaces, or cannot accommodate the planned circuits safely. A panel upgrade may also require changes to service conductors, grounding, bonding, or utility coordination.

A panel upgrade is not automatically required whenever a house is rewired. An electrician should assess the existing equipment and calculate the expected electrical load before recommending replacement.

For additional budgeting, see the site's electrical-panel-upgrade and subpanel-installation cost guides.

Number of floors and building layout

A single-story house with an accessible attic may be easier to rewire than a three-story home with finished ceilings and limited pathways between floors.

Long distances between the panel and electrical points, multiple additions, detached structures, and unusual architectural features can also increase the amount of work.

Wall and ceiling restoration

The electrical portion of a rewire may require openings to reach hidden cables. Drywall patching, plaster repair, painting, trim restoration, and tile replacement may be additional services.

Clarify whether the electrician will make only the openings needed for wiring or will restore the surfaces afterward. In many projects, a separate drywall contractor or painter handles the finish work.

Local code and permit requirements

Permits, inspections, grounding requirements, circuit protection, and other code provisions vary by jurisdiction and project scope. Local authorities may require specific upgrades when substantial electrical work is performed.

A contractor should identify permit requirements before work begins and explain which corrections are required to pass inspection. Unpermitted work can create problems during resale, insurance reviews, and future renovations.

Labor vs. materials

Labor is usually one of the largest components of a whole-house rewiring budget. Electricians must inspect the system, plan circuit routes, install cables, connect devices, label circuits, and test the completed installation.

Materials include wire, electrical boxes, receptacles, switches, connectors, staples, protective devices, and potentially a new panel or grounding components.

Cost component	Illustrative allowance for a $20,000 project
Electrical labor	$10,000–$14,000
Wiring and installation materials	$2,000–$4,000
Panel, breakers, and related equipment	$1,000–$3,000
Permits, testing, and inspections	$200–$800
Other project costs and contingencies	Remaining budget

This breakdown is illustrative rather than a standard national percentage. Categories can overlap, and panel work or restoration may be included in another line item. The final proportions depend on the property's condition and the contractor's pricing structure.

Labor costs reflect more than the time spent pulling cable. Older homes can require troubleshooting, careful routing around existing finishes, coordination with other trades, and repeated testing. A lower material quote does not necessarily mean a lower total project price.

When comparing estimates, review the complete scope and exclusions instead of comparing the hourly rate or wire price alone.

Hidden and extra costs

A whole-house rewire can uncover problems that were not visible during the initial inspection. Building a contingency into the budget helps prevent these discoveries from becoming financial surprises.

Additional work	Estimated cost
Electrical panel upgrade	$1,300–$4,000
New subpanel	$500–$2,000
Drywall repair and patching	$200–$1,500+
Interior painting after repairs	$300–$2,000+
Permit and inspection fees	$100–$500+
New outlets or switches beyond the base scope	$100–$300+ per point
Additional dedicated circuit	$150–$500+
Service entrance or major service changes	$1,000–$5,000+
Asbestos testing or specialist remediation	Varies by material and scope

These amounts are broad allowances and may not be additive. Some contractors include permits, device installation, or basic patching in their main quote. More extensive panel or service work can also fall outside the ranges shown.

Wall and ceiling repairs

A rewire often requires access openings, but the number and size of openings depend on the construction and cable routes. Drywall may be relatively straightforward to repair, while original plaster, decorative ceilings, and custom finishes can be much more expensive to restore.

Ask for an estimate covering both electrical work and finish restoration. If restoration is excluded, obtain a separate quote before the project begins.

Panel and service upgrades

An electrician may discover that the panel has inadequate capacity, unsafe components, or no suitable spaces for new circuits. The home may also require changes to the service equipment or grounding system.

These upgrades can add thousands of dollars, so the initial assessment should identify likely requirements. If a utility service change is needed, coordination and scheduling may affect the timeline.

Hazardous materials

Older homes may contain asbestos in certain insulation, coatings, flooring, or other building materials. Lead-based paint may also be present in older finishes. Neither should be disturbed casually during electrical work.

If suspect materials are identified, testing and specialist remediation may be necessary before walls or ceilings can be opened. Costs depend on the material, its condition, and the amount of affected area.

Additional electrical capacity

Homeowners often use rewiring as an opportunity to prepare for new appliances, electric heating, workshop equipment, or an EV charger. These additions may require dedicated circuits or a service-capacity assessment.

For related planning, review the site's 240v-outlet-installation, ev-charger-installation, and standby-generator-installation cost guides. Their costs are separate unless the electrical contractor specifically includes the associated work in the rewire quote.

Regional and climate notes

Electrical labor rates, permit fees, housing construction, and contractor availability vary across the United States. National estimates are useful for initial planning, but local quotes are more reliable for setting a project budget.

High-cost metropolitan areas

Major metropolitan areas with higher labor rates, expensive housing, and strong demand for licensed trades may fall toward the upper end of national estimates. Parking, building access, historic preservation rules, and coordination with building management can also affect the price.

In condos and multifamily buildings, contractors may need to coordinate electrical shutdowns, building access, and shared service equipment. Confirm whether the estimate includes these arrangements.

Older homes in the Northeast and Midwest

Many older homes in the Northeast and Midwest have plaster walls, multiple renovations, and aging electrical systems. Some properties may contain knob-and-tube wiring or other legacy installations.

The challenge is not simply replacing the conductors. Maintaining historic finishes, routing cables through dense construction, and complying with local requirements can increase labor and restoration costs.

Hot climates and high cooling loads

In hot regions, central air conditioning and other large cooling loads can influence electrical planning. Rewiring may expose inadequate circuits or a panel that needs evaluation for the home's current and planned loads.

Heat alone does not mean a house must be rewired. The decision should be based on the actual condition of the wiring, equipment ratings, circuit protection, and the electrical demands of the property.

Coastal and humid environments

Humidity, salt exposure, flooding, and moisture intrusion can affect electrical equipment and connections. Homes exposed to storms or water damage may require a more extensive assessment before damaged wiring can be returned to service.

Outdoor circuits and equipment must be suitable for their environment and installed with the required protective measures. Flood-damaged electrical systems should be assessed by qualified professionals before power is restored.

Rural and remote areas

Homeowners in rural locations may have fewer nearby electrical contractors or longer travel distances for service. Limited contractor availability can affect scheduling and total labor charges.

Where utility service changes or inspections require additional coordination, the project may also take longer. Obtain several qualified local estimates when possible, particularly for large or older properties.

Signs you need the work

Some electrical problems require immediate attention, while others justify a professional inspection and planned replacement. A single symptom does not always mean the entire house needs rewiring.

Frequent breaker trips

A breaker that trips repeatedly may indicate an overloaded circuit, a short circuit, a ground fault, or a defective component. Resetting it repeatedly without identifying the cause can leave a potentially dangerous problem unresolved.

An electrician can determine whether the problem requires a circuit change, additional capacity, equipment replacement, or more extensive rewiring.

Burning smells, sparks, or warm outlets

A burning odor, visible scorching, buzzing accompanied by heat, sparks, or an unusually warm outlet can indicate a dangerous electrical fault.

Stop using the affected circuit if it is safe to do so, and seek prompt professional assistance. If there is smoke or a fire, leave the area and contact emergency services. Do not remove outlet covers or handle damaged wiring yourself.

Flickering or dimming lights

Occasional changes in brightness can have several causes, including a loose connection, an overloaded circuit, or a problem with the electrical service. Flickering that repeatedly occurs when appliances operate should be investigated.

A whole-house rewire may be appropriate if an inspection finds widespread deterioration, but the symptom alone does not establish that replacement is necessary.

Two-prong outlets and missing grounding

Older two-prong outlets may indicate that a home has ungrounded branch circuits. Replacing the receptacles with three-prong outlets does not create an equipment grounding path where none exists.

An electrician can evaluate grounding and determine the appropriate compliant solution for the circuits. Depending on the home's wiring and requirements, this may involve rewiring some or all of the affected areas.

Visible damaged or brittle wiring

Cracked insulation, exposed conductors, damaged cables, rodent chewing, and deteriorated connections are reasons to arrange an inspection. The appropriate response depends on how widespread the damage is and whether other portions of the system remain safe.

Avoid touching exposed wires or attempting temporary repairs. If the installation presents an immediate hazard, keep people away and have a qualified professional assess it.

An older home with undocumented electrical work

A house that has undergone repeated renovations may contain splices, extensions, or circuits that were installed without consistent documentation. A professional inspection can identify whether the installation is safe and whether the wiring matches the home's current electrical demands.

Age alone does not automatically require a full rewire. The condition of the conductors, quality of previous work, grounding, circuit protection, and intended future use are more important considerations.

Buying or renovating a house

A home inspection may identify outdated wiring or recommend a specialist evaluation. Before purchasing an older property, ask for an electrical inspection when the report raises concerns about the wiring or panel.

If a major renovation is planned, rewiring before new drywall, cabinetry, and flooring are installed can reduce restoration expenses. The electrical plan should account for future appliances, lighting, outlets, and other expected loads.

How to save money on a house rewire

Reducing the cost of a rewire starts with defining the work clearly and avoiding unnecessary changes during construction.

Get multiple detailed estimates

Request at least three estimates from qualified electrical contractors when practical. Each estimate should cover the same general scope so that pricing differences can be evaluated fairly.

Compare the number of circuits, devices, panel work, permit fees, testing, and restoration. A quote that appears cheaper may exclude important work that another contractor has included.

Rewire during a renovation

If walls and ceilings are already open, electricians may have easier access to wiring routes. Coordinating the rewire with a kitchen remodel, bathroom renovation, or major interior renovation can reduce duplicated labor and finish-repair costs.

However, electrical work should be coordinated with the renovation schedule. Have the wiring inspected before walls are closed.

Keep the existing layout where practical

Moving every outlet, switch, and light can increase labor and material costs. Keeping suitable existing locations may reduce the number of new cable routes and wall openings.

It is still worth correcting unsafe placements or adding essential outlets where required. The goal is to avoid unnecessary changes, not to preserve a layout that does not meet the household's needs.

Make access easier

Before work starts, remove furniture and stored items from work areas when possible. Clear access to the attic, basement, crawl space, electrical panel, and affected rooms.

Ask the contractor whether any preparation tasks would reduce labor charges. Do not remove electrical components or open walls containing unknown wiring without professional guidance.

Separate electrical and restoration work carefully

Some electricians provide basic patching, while others focus exclusively on electrical installation. Obtain separate finish-work quotes if needed, and make sure responsibilities are clearly defined.

Using a qualified restoration contractor can be practical when the project involves substantial plaster, painting, tile, or custom trim. Coordinate the work so electrical inspections occur before finishes are restored.

Avoid unnecessary panel replacement

A panel upgrade can be a significant additional expense. Ask the electrician to explain why replacement is needed and whether the existing panel can safely support the proposed circuits.

Do not reject a necessary upgrade simply to reduce the quote. The objective is a safe, code-compliant installation, not the lowest upfront price.

Plan future electrical needs

If an EV charger, workshop, new HVAC system, or electric appliance is likely to be installed soon, discuss it during the initial design. Planning for future loads may avoid reopening walls or making another major electrical change later.

The contractor should calculate loads and explain whether the existing service has adequate capacity. Avoid installing oversized equipment without a clear technical reason.

Keep a contingency fund

Set aside approximately 10% to 20% of the estimated project budget when the home's wiring condition or accessibility is uncertain. This is a planning recommendation, not a guaranteed allowance for every project.

A contingency is particularly useful for older houses where concealed damage, outdated modifications, or finish problems may only become visible after work begins.

DIY or hire

Whole-house rewiring should generally be completed by a qualified electrician. Electrical work involves shock and fire risks, and mistakes hidden inside walls can remain unnoticed until a serious failure occurs.

Local rules differ on whether homeowners can perform certain electrical work on an owner-occupied property. Even where homeowner permits are permitted, the work must comply with applicable requirements and pass required inspections.

Why professional rewiring matters

A professional electrician can determine appropriate wire sizes, circuit ratings, grounding arrangements, and protective devices. The electrician can also assess electrical loads, coordinate panel work, test completed circuits, and arrange required inspections.

Incorrect connections, overloaded conductors, inadequate grounding, and improperly installed protective devices can create hazards that are not obvious during a visual inspection.

Tasks homeowners may handle

Depending on the project and contractor's requirements, homeowners may be able to:

• Move furniture and clear work areas.
• Remove stored items from accessible attic or basement work areas.
• Choose outlet, switch, and lighting locations before installation.
• Arrange separate painting or restoration work.
• Document existing appliances and planned electrical additions.

Any work involving electrical conductors, panel components, or energized equipment should be left to appropriately qualified people. Never assume a wire is safe to touch simply because a switch has been turned off.

What to expect from a professional

The electrician should inspect the existing system, explain the proposed scope, identify likely code requirements, and provide a written estimate. During the project, the contractor should coordinate shutdowns, keep work areas safe, and test the completed circuits.

Ask how the electrician will handle unexpected conditions, inspections, and changes to the agreed price. Confirm that the work will be performed under the required license and permit arrangements.

Repair or replace

The choice between repairing existing wiring and replacing it depends on the condition and extent of the problem. A limited defect does not necessarily require a complete house rewire, but a collection of unrelated faults can indicate a broader problem.

When repair may be sufficient

A targeted repair may be appropriate when damage is localized, the remaining wiring is in sound condition, and the electrician confirms that the system is safe. Examples include a damaged cable section, a defective connection, or an isolated circuit problem that can be corrected without leaving other hazards unresolved.

The repair should address the cause, not merely the visible symptom. Repeated breaker trips, for example, require diagnosis rather than simply replacing the breaker with another device.

When replacement makes more sense

Full or substantial rewiring may be appropriate when insulation is deteriorated throughout the house, the wiring has extensive damage, grounding is inadequate across many circuits, or unsafe alterations are widespread.

Replacement can also make sense during a major renovation when existing cables cannot support the planned layout or electrical requirements. An electrician should explain why repair is insufficient and identify the sections that need replacement.

Compare immediate and long-term costs

A targeted repair costs less initially, but repeated repairs can become expensive if the underlying wiring is deteriorated. Conversely, replacing a safe, serviceable system solely because it is old may not be necessary.

Ask the electrician to distinguish urgent safety corrections from recommended improvements and optional upgrades. This allows the work to be prioritized while maintaining a safe installation.

Check insurance and resale implications

Some insurers may ask about outdated wiring, known hazards, or previous electrical modifications. Policies and underwriting requirements vary, so homeowners should confirm the requirements directly with their insurer.

Document permitted work, inspection results, and invoices. These records can help answer questions from future buyers, inspectors, and insurance providers.

How to hire an electrician

Choosing a qualified contractor is essential because rewiring affects nearly every part of a home's electrical system.

Verify licensing and insurance

Check the contractor's electrical license through the relevant state or local licensing authority. Requirements vary by jurisdiction, and the person or business performing the work must meet the applicable rules.

Confirm general liability insurance and ask whether workers' compensation coverage applies to the crew. Request references for comparable residential rewiring projects, particularly older homes if that matches the property.

Request a written scope of work

A good estimate should identify the areas being rewired, the number and type of circuits, expected outlets and switches, panel work, permits, testing, and restoration responsibilities.

It should also state whether the quote covers removal of old wiring, disposal, code-required corrections, and unexpected damage. Clarify whether pricing is fixed or subject to change when concealed conditions are discovered.

Questions to ask before signing

• Does the estimate cover a complete rewire or only selected circuits?
• Which outlets, switches, junction boxes, and lighting points are included?
• Is the existing electrical panel suitable for the planned work?
• Are grounding, bonding, and required circuit-protection upgrades included?
• Who obtains permits and schedules inspections?
• Are drywall patching, plaster repair, and painting included?
• How will unexpected problems be documented and priced?
• What is the expected project schedule and power-shutdown plan?
• Who supervises the work and performs final testing?
• What workmanship warranty and documentation will be provided?

Review payment terms and change orders

The contract should establish the price, payment schedule, start date, estimated duration, and process for approving additional work. Avoid relying on verbal promises about what is included.

If concealed damage or additional code requirements are discovered, ask for a written explanation and revised price before authorizing non-emergency additions. Keep copies of permits, inspection results, invoices, and warranties.

Understand the project timeline

A straightforward rewire may take several days to a week or longer, while a complete rewire of a large or complicated house can take multiple weeks. Permit approvals, utility coordination, wall repairs, and inspection scheduling can extend the overall timeline.

Ask whether the home can remain occupied during the work and which utilities or circuits will be unavailable. Families may need to arrange temporary accommodation if the project involves extensive demolition, prolonged power interruptions, or safety restrictions.

Final budgeting advice

The cost to rewire a house in 2026 is best estimated using three pieces of information: the home's size, the condition and accessibility of the existing wiring, and the precise scope of work. A national planning range of $1,300 to $30,000 covers a broad mix of projects, while $10,000 to $30,000 is a more useful starting point for typical whole-house rewiring.

Before committing to a contractor, obtain a detailed inspection and compare written estimates with consistent scopes. Include potential panel work, permits, wall restoration, and a contingency for concealed problems. A well-planned rewire improves electrical safety, supports modern household needs, and reduces the likelihood of paying for repeated, piecemeal work.
