Rewiring a house from aluminum to copper typically costs $10,000-$30,000 for a full replacement, with smaller homes and accessible wiring at the low end and larger, finished homes at the high end. Price depends on square footage, circuit count, wall access, local labor rates, and whether the work includes drywall repair or electrical panel upgrades.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full copper rewire | $8,000 | $18,000 | $35,000+ | Typical whole-house project; finish repairs can raise the total |
| Per square foot | $6 | $12 | $20+ | Varies with access, circuit count, and regional labor |
| Aluminum-wire remediation | $1,500 | $3,000 | $6,000+ | Connector or device work; not a full rewire |
| Panel replacement, if needed | $1,500 | $3,000 | $5,000+ | Separate scope, affected by capacity and code requirements |
What a full copper rewire costs by house size
For a typical U.S. home, electricians often quote about $6-$20 per square foot, including wire and installation. A 1,000-square-foot home may run $8,000-$18,000; a 1,500-square-foot home, $12,000-$27,000; and a 2,000-square-foot home, $16,000-$35,000 or more. These are broad project ranges, not fixed national rates.
A basic estimate assumes standard copper branch-circuit wiring, ordinary access, and no major panel or finish upgrades. Two-story layouts, finished plaster walls, many devices, and limited attic or basement access can push a quote above the per-square-foot midpoint. Assumptions: U.S. licensed electrician, standard copper cable, normal access, and no extensive structural repairs.
How wire, electrician hours, and patching shape the quote
Labor commonly accounts for the largest share of a rewire. The table shows typical allowances; actual quotes depend on the home’s circuit layout and local wage rates.
| Quote component | Typical price | Pricing basis | What changes it |
|---|---|---|---|
| Copper wire and boxes | $1,500-$5,000 | Materials, often $0.50-$2 per sq ft | Wire gauge, circuit count, and copper market prices |
| Electrician labor | $5,000-$18,000 | $75-$150 per hour per electrician | Crew size, access, and time spent fishing cable |
| Devices and breakers | $500-$3,000 | Per outlet, switch, or circuit | GFCI/AFCI protection and device quantity |
| Permits and inspection | $200-$1,000 | Per project | Municipality and scope of work |
| Drywall repair and paint | $1,000-$6,000+ | Per room or affected area | Wall openings, plaster, and finish matching |
Why square footage, wall access, and circuit count matter
Square footage is only a starting point. A 1,200-square-foot home with 30-40 outlets and open basement access may cost less than a 1,000-square-foot house with plaster walls, no attic access, and 50 or more devices. Each added circuit, kitchen appliance, or dedicated HVAC connection increases wire, breaker, and labor needs.
Access and electrical scope can change the estimate more than a few hundred square feet. Homes with knob-and-tube wiring, brittle insulation, crowded panels, or concealed junctions may require troubleshooting and additional replacement. A 100-amp panel may also need a service upgrade if new loads or local code requirements call for it; that work can add roughly $1,500-$5,000.
Keep the copper rewire price down by controlling scope
Ask the electrician to identify which circuits are aluminum and whether the proposal replaces all branch wiring or only selected runs. A written scope should list outlets, switches, circuits, panel work, permits, and finish restoration. Comparing bids is useful only when each contractor is pricing the same work and code-compliant materials.
Preserving sound finishes and avoiding unnecessary panel or device upgrades can reduce the total. If walls are already open during a renovation, scheduling the electrical work then may cut access and patching expenses. Homeowners can clear work areas and move furniture, but should not handle live wiring or perform unpermitted electrical work.
How regional electrician rates shift the total
Labor-intensive rewiring generally costs more in high-wage metropolitan areas than in lower-cost rural markets. Large coastal cities may run 15%-35% above national midrange estimates, while some rural or lower-cost regions may come in 10%-20% below them. Local permit fees, contractor availability, and the age and construction style of the housing stock also affect bids.
Use regional differences as a comparison, not as a substitute for a local inspection. An older city row house may require more finish work than a newer suburban home even if both have the same floor area. Request an on-site quote that separates electrical work from drywall and paint charges.
How long electricians need to replace aluminum branch wiring
A straightforward rewire may take a crew of two or three electricians about 3-7 working days. A large, occupied home with difficult access can take one to three weeks, especially when work is phased room by room. At $75-$150 per electrician-hour, added labor time can increase the total quickly.
Ask whether the price includes temporary power, furniture protection, daily cleanup, and return visits for inspection. Rush scheduling or work outside normal hours may carry an added charge, while an occupied home may need extra setup and protection compared with a vacant property.
When permits, panel work, and drywall repairs add charges
Most full rewires require an electrical permit and inspection, but rules and fees vary by jurisdiction. An inspector may require current protections such as AFCI or GFCI devices in applicable locations. If the existing panel lacks space or capacity, a panel replacement or service upgrade is a separate expense and should be itemized rather than buried in a lump-sum quote.
Confirm who obtains the permit and what restoration is included before approving work. Electricians may cut small access openings to route cable, but patching, texture matching, and painting are often excluded. A separate drywall contractor may charge $1,000-$6,000 or more depending on the number of rooms and finish quality.
Full copper replacement versus aluminum-wire connector repair
Replacing all aluminum branch wiring is different from making approved connections at devices and junctions. Connector-based remediation may cost roughly $1,500-$6,000+, depending on the number of outlets and switches, access, and the repair method accepted by the authority having jurisdiction. It can be less disruptive, but it leaves the aluminum wiring in place.
Compare the written scope and method, not just the lower total. A full rewire replaces branch circuits with copper; remediation addresses connection points and may be appropriate for some homes after evaluation by a qualified electrician. Get a clear explanation of what wiring remains, what warranty applies, and whether the solution meets local requirements.
