Cost to Rewire a House: What Homeowners Pay

Rewiring a house costs $4,000 to $20,000 for most homes, or roughly $4 to $10 per square foot for standard projects, according to rewiring cost per square foot data published by SoFi (January 30, 2026). Older homes with closed walls, knob-and-tube wiring, or undersized panels can push that number higher. The wide spread you see in quotes, sometimes $6,500, sometimes $24,000 for the same size house, comes down to three variables that move independently: how easy it is to access the walls, what wiring type is being replaced, and whether the electrical panel needs an upgrade.

AI engines and contractor platforms disagree sharply on this topic because they’re often quoting different scopes. Partial rewiring job estimates from Thumbtack (April 9, 2026) show an average of $672 to $2,116, that reflects single-room or circuit-level jobs from their platform data, not a full-house rewire. A full rewire on a 2,000 square foot home is a different project entirely.

This guide covers what a full rewire costs by home size, what drives quotes up or down, signs your home needs rewiring, whether you can skip the drywall demo, and how to decide between rewiring before selling and selling as-is.

What Does It Cost to Rewire a House?

Rewiring costs vary based on home size, wall accessibility, wiring type, and whether a panel upgrade is needed. The ranges below reflect full-house rewires by a licensed electrician, including labor, materials, and permit fees, but excluding major panel upgrades unless noted.

Cost by Home Size

Home Size	Low Estimate	High Estimate	Per Sq Ft Range
1,000 sq ft	$4,000	$10,000	$4, $10
1,500 sq ft	$6,000	$15,000	$4, $10
2,000 sq ft	$8,000	$20,000	$4, $10
2,500 sq ft	$10,000	$25,000	$4, $10
3,000+ sq ft	$12,000	$30,000+	$4, $10+

Based on per-sq-ft ranges reported by SoFi (January 30, 2026) and Elliot Services. Older homes with closed walls or code-upgrade requirements may exceed the high estimates shown. Verify current rates with local licensed electricians before budgeting.

The $4 per square foot end applies when an electrician can route wires through an open attic, unfinished basement, or accessible crawl space with minimal wall cutting. The $10-plus end applies when walls are finished, the home has plaster construction, or the wiring type requires a full replacement rather than a targeted update.

Labor accounts for a significant share of the total, often more than half, because electricians must snake wire through wall cavities, ceilings, and floor systems. The physical conditions of your home determine how many hours that takes.

Partial Rewire vs. Full Rewire Cost

A partial rewire targets specific circuits, rooms, or problem areas, for example, replacing aluminum branch circuits in a kitchen or updating a bathroom to meet ground-fault protection requirements. A full rewire replaces all wiring throughout the home.

Partial rewires cost significantly less. A single room or circuit group might run $1,000 to $3,500 depending on scope. This is the category Thumbtack’s $672 to $2,116 average covers: jobs where one area, one panel section, or one circuit type is addressed rather than the whole house.

A full rewire is necessary when the wiring type itself is the hazard, knob-and-tube, cloth-wrapped, or widespread aluminum branch circuits, or when a home inspection flags problems throughout the home rather than in isolated spots.

Cost to Rewire a 2,000 Square Foot House

Rewiring a 2,000 square foot house costs approximately $8,000 to $20,000 for a standard project with reasonable wall access.

The lower end of that range applies when an electrician can work through an accessible attic, basement, or crawl space, the home has a 100-amp or 200-amp panel in good condition, and the existing wiring is plastic-sheathed copper that can be partially retained or easily replaced. The upper end applies when walls are finished throughout, the home is 40 or more years old, and a panel upgrade is included.

Homes with knob-and-tube wiring (pre-1940s construction) or aluminum branch wiring (common in 1960s and 1970s homes) typically land at or above the high end of the range because those systems require full replacement rather than targeted updates, and may trigger additional code-compliance requirements under your local jurisdiction’s adoption of National Electrical Code requirements.

A panel upgrade alone adds an estimated $1,000 to $3,000 to the project. If your home has a 60-amp panel, an upgrade to 200-amp service is almost always required before a full rewire can pass inspection.

What Drives the Cost of Rewiring a House?

The same 2,000 square foot house can get quotes ranging from $8,000 to well over $20,000. Three variables explain most of that spread.

Labor and Wall Access

Labor is the largest cost driver in most rewiring projects. Electricians charge for the time it takes to route wire from point to point, and that time varies enormously based on what’s in the way.

Open walls (unfinished basements, accessible attics, exposed framing in garages) are the fastest and cheapest to work in. Finished drywall walls require cutting small access holes near outlets, switches, and junction boxes, then routing wire through wall cavities using fish tape and flexible drill bits.

Homes with plaster and lath wall construction are the most labor-intensive. Plaster is dense, brittle, and difficult to patch cleanly. Electricians either cut more carefully (slower) or open more of the wall (more patching later). Either way, the labor hours go up.

Budgeting for older homes with simultaneous plumbing and electrical issues is common, see what it costs to replumb a house for the parallel repair cost picture.

Wiring Type: Knob-and-Tube, Aluminum, and Cloth-Wrapped

What wiring type your home has determines whether a partial update is possible or a full replacement is required.

Knob-and-tube wiring (common in homes built before 1940) uses separate hot and neutral conductors strung through ceramic knobs and tubes. It has no ground wire, and the insulation becomes brittle over decades. Most jurisdictions require full replacement when any permitted work begins.

Aluminum branch wiring (common in 1960s and 1970s construction) expands and contracts more than copper, which loosens connections at outlets and switches over time. Full replacement with copper is the safest option, though some electricians use approved aluminum-to-copper connectors (COPALUM or AlumiConn) to reduce scope and cost. If your home has aluminum wiring, get a written scope of work that specifies whether the quote covers full replacement or connection remediation.

Cloth-wrapped wiring (common in homes from the 1940s through 1960s) may still have functional copper conductors inside, but the cloth insulation degrades and can crack. Whether a full replacement is required depends on condition and local code.

Homes with knob-and-tube or aluminum wiring require full replacement in most cases, that scope difference alone can double or triple the cost compared to a home that just needs modernization of a few circuits.

Electrical Panel Upgrade

The panel is the gateway for every circuit in your home. If it’s undersized or outdated, a rewire isn’t complete without addressing it.

• 60-amp panels are obsolete and cannot safely support a modern household. Upgrade to 100-amp or 200-amp service is required before a full rewire.
• 100-amp panels are sufficient for many smaller homes but may need replacement if you’re adding circuits for EV charging, a home office, or major appliances.
• 200-amp panels are the current standard for most single-family homes.

A panel upgrade typically adds $1,000 to $3,000 to the project, depending on whether the service entrance (the line from the street to your panel) also needs upgrading.

Permits and Inspection Fees

Electrical rewiring requires a permit in virtually every U.S. jurisdiction. The permit triggers an inspection after rough-in wiring is complete, before walls are closed. A second inspection confirms the finished work.

Permit fees vary by municipality. They typically fall in the range of a few hundred dollars for a full-house project, though the specific amount depends on your city or county’s fee schedule.

Working without a permit creates liability at resale. Buyers’ inspectors and title companies flag unpermitted electrical work, and some lenders won’t finance a home with known unpermitted improvements.

National Electrical Code requirements (NFPA 70) set the minimum safety standards that local inspectors apply. Your jurisdiction adopts a specific edition, check with your local building department to know which one is in effect.

Regional Labor Rates

Electrician hourly rates vary by region. Metropolitan areas with high demand and cost of living tend to run $80 to $130 or more per hour. Rural markets may be lower. Material costs, particularly copper wire prices, fluctuate as well. The per-square-foot ranges above reflect national averages; your local quotes may land above or below depending on where you live.

Signs Your House Needs Rewiring

Most homeowners don’t discover a wiring problem until something goes wrong. The signs below tell you not just that a problem exists, but roughly what it will cost to fix.

Urgent Signs (Act Immediately)

These indicate active fire risk. Call a licensed electrician before doing anything else.

• Burning smell near outlets or switches, wire insulation is overheating. This is a pre-fire condition.
• Warm or discolored outlet covers, heat is building up inside the box.
• Scorch marks or char around outlets, arcing has already occurred.
• Buzzing, sizzling, or sparking, a loose or failing connection is the likely cause.
• Small shocks when plugging in appliances, the circuit is not properly grounded.

Any of these signs means the wiring in that area, and likely adjacent areas, needs immediate evaluation. The cost implication: urgent signs often indicate conditions that require full replacement rather than targeted repairs.

Functional Signs (Schedule Soon)

• Frequent circuit breaker trips, the system can’t handle the load your home puts on it. This often points to a panel that’s too small or circuits that are overloaded.
• Flickering or dimming lights, especially when appliances cycle on. This suggests voltage fluctuations from loose connections or overloaded wiring.
• Two-prong outlets throughout the home, ungrounded outlets indicate pre-1970s wiring. The entire system likely predates modern grounding standards.

Functional signs don’t require emergency response, but they do indicate a wiring system that’s operating outside safe parameters. A partial rewire targeting problem circuits may resolve the issue, or a full assessment may reveal more widespread problems.

Age-Based Triggers

If your home was built before the mid-1970s and has never had a wiring update, the wiring type itself may be the problem, regardless of whether symptoms have appeared yet.

• Pre-1940s homes often have knob-and-tube wiring, which has no ground wire and aging insulation.
• 1960s and 1970s homes may have aluminum branch wiring, which carries a documented connection-failure risk.
• Any home with a 60-amp or fuse-based panel is almost certainly running on a system that cannot safely support modern loads.

Age-based wiring conditions typically require full replacement. The cost implication: these projects land at the high end of the range, often $10,000 to $20,000 or more for a 2,000 square foot home.

Can You Rewire a House Without Removing Drywall?

Yes, a house can often be rewired without removing drywall. The technique, known as “fishing,” routes new cable through wall cavities using access points above and below rather than opening the wall face.

How Wire Fishing Works

An electrician identifies a routing path from the electrical panel to each outlet, switch, or fixture location. Rather than cutting open the wall between those points, they work from above (attic) or below (basement or crawl space) to drill through wall plates and feed cable down through the cavity.

Crawl space access and common issues affect this directly, a clean, accessible crawl space gives electricians a clear run under the floor system; a wet, obstructed, or shallow crawl space limits routing options and adds time.

Small access holes are cut near outlets, switches, and junction boxes, typically palm-sized or smaller, to connect the fished wire to devices. These are patched after the inspection passes.

Tools Electricians Use

• Fish tape, a stiff coiled steel strip that can be pushed through a wall cavity and used to pull wire back through.
• Flexible drill bits (also called bell hangers or long-reach bits), let electricians drill through wall plates from the access point rather than cutting into the face of the wall.
• Magnetic wire pullers, a magnet-and-stud system that allows cable to be guided through cavities when direct access is limited.

For more detail on the technique, fishing electrical wire through walls from Family Handyman covers the process step by step.

When Drywall Removal Is Unavoidable

Some homes can’t be fished without opening walls. The main conditions:

• Plaster and lath walls, too dense and fragile for reliable fishing without breaking large sections.
• No attic or basement access, slab-on-grade homes with fully finished interiors have no routing path above or below.
• Complex horizontal runs, wiring that needs to travel horizontally across a wall (rather than vertically through a cavity) usually can’t be fished without opening the wall.
• Firestop blocking, older homes sometimes have horizontal blocking inside wall cavities that stops the fish tape mid-run.

When drywall removal is needed, a good electrician minimizes the opening and patches afterward. Ask whether patching is included in the quote, or whether you need to arrange a separate drywall contractor.

What to Ask Before You Get a Quote

• How will you access the wiring (attic, basement, crawl space, or wall cuts)?
• What size openings should I expect near outlets and switches?
• Is wall patching included, or is that a separate cost?
• What’s included in the permit fee line, does the quote cover inspection scheduling?
• Does the quote include panel work, or is that a separate estimate?

Is It Worth Rewiring an Old House?

Rewiring an old house is worth it when the existing system is unsafe, uninsurable, or unable to support modern electrical loads. It is rarely a pure value-add at resale, but the case for rewiring isn’t primarily about ROI.

Safety and Insurance Implications

Homes with knob-and-tube or aluminum branch wiring carry a documented electrical fire risk. NFPA data on home electrical fires consistently identifies wiring faults as a leading ignition source.

The insurance dimension is practical: many insurers surcharge policies or decline to renew coverage for homes with known knob-and-tube or aluminum branch wiring. Some homebuyers discover that their preferred insurer won’t bind a policy until an electrical inspection confirms the system meets minimum standards.

Impact on Home Sale

A home inspector will flag knob-and-tube, aluminum branch wiring, two-prong outlets, and undersized panels. A financed buyer’s lender may require electrical upgrades as a loan condition before closing, meaning the repair happens on the buyer’s timeline, not yours, with the cost often negotiated out of your proceeds.

A home inspector report that lists electrical hazards gives a buyer negotiating leverage. Even if they don’t walk, they’re likely to ask for a price reduction or a repair credit.

When to Rewire Before Selling vs. Selling As-Is

Rewiring before listing makes sense when: – The home has widespread problems that will appear on any inspection report – You have time (the project takes weeks, including permit scheduling) – The local buyer pool is heavily financed rather than cash-heavy – The estimated cost of rewiring is less than the likely price reduction a buyer would demand

Selling as-is makes sense when: – The rewiring cost doesn’t pencil out against the expected price improvement – Your timeline is short – You can reach cash buyers who price the condition into the offer rather than making it a contingency

How to Budget and Pay for Rewiring

Rewiring is a safety repair, not a cosmetic upgrade, but that doesn’t make it any easier to fund. Here are the main options homeowners use.

Home Equity Loans or HELOCs

If you’ve built up equity, a home equity loan or home equity line of credit (HELOC) typically offers lower interest rates than unsecured options. You can borrow enough to cover labor, materials, permit fees, and patching in a single draw. The risk: your home secures the loan, so missed payments carry real consequences.

Home Improvement Loans

Unsecured home improvement loans don’t require equity but carry higher interest rates. They work well when you need to avoid tapping your mortgage or when a HELOC isn’t available due to insufficient equity.

Cash or Savings

For partial rewires or isolated panel upgrades, paying cash avoids interest entirely. Leave a contingency buffer, electrical projects frequently turn up additional issues once the electrician is inside the walls.

Credit Cards (As a Last Resort)

A card with a 0% promotional period can bridge a gap on a smaller project if you have a firm payoff plan. Carrying a high balance long-term on a $10,000-plus project gets expensive quickly.

Grants, Rebates, and Energy Programs

Some state and local programs offer incentives for electrical upgrades, particularly those tied to energy efficiency improvements. The state energy efficiency incentive programs database at DSIREUSA.org (a program of N.C. Clean Energy Technology Center) is the most comprehensive public directory of state-level incentive programs in the U.S. Check your city or county building department as well, some municipalities offer low-interest home repair loans specifically for safety upgrades.

Sellers preparing an older home often face multiple repair decisions at once. Understanding termite inspection costs alongside electrical costs helps build a realistic pre-sale repair budget.

How to Get an Accurate Rewiring Quote

Getting an accurate quote means giving the electrician enough information to price your actual project, not a generic one.

1. Identify your home’s wiring type. Look in the electrical panel and attic. Cloth-wrapped wiring has a fabric outer layer; aluminum wiring is silver-colored rather than copper-colored; plastic-sheathed copper (Romex) is the modern standard.
2. Note your panel amperage. It’s stamped on the main breaker. A 60-amp, 100-amp, and 200-amp panel each carry different upgrade costs.
3. Assess wall accessibility. Do you have an unfinished basement, an accessible attic, or a crawl space that runs the length of the house? Sketch out what’s open and what’s finished.
4. Count circuits and two-prong outlets. This gives the electrician a baseline for scope before the site visit.
5. Pull your local permit cost from your city or county building department website. Some jurisdictions post fee schedules online; having this number confirms whether a quote’s permit line is reasonable.
6. Get at least three written quotes from licensed electricians. Each quote should specify whether it includes permit fees, panel upgrade (if needed), and wall patching.
