Outdated electrical wiring causes tens of thousands of home fires in the U.S. every year, and aging wiring also drags down home value and can void insurance. Unlike most home projects, electrical shortcuts can be fatal — so understanding real costs matters more than chasing the cheapest bid.

How much does electrical wiring cost in 2026? Most electrical wiring projects run $150 to $15,000 depending on scope. A single new circuit costs $150–$500; a 100A-to-200A panel upgrade runs $1,000–$3,000; a whole-home rewire ranges from $3,500 for a small home to $15,000+ for a larger one. Licensed electrician labor runs $75–$150 an hour.

Electrical Wiring Cost by Project
Scope sets the price. Typical 2026 ranges, parts and labor:
These are national ranges. Labor in high-cost metros like New York, Los Angeles, and Chicago runs 30–50% above average, while rural areas fall at the lower end. A smaller, targeted fix like an outlet repair sits well below these numbers — a useful comparison when weighing a single fix against a full rewire.
What Drives Electrical Wiring Costs
The gap between a $500 job and a $15,000 one comes down to five factors.
- Home size and layout. Rewiring is priced at $2 to $6 per square foot. A single-story ranch with an accessible attic costs far less than a multi-story home with finished walls — the same 2,000-square-foot home can run roughly $6,000 with open framing or $12,000 with finished walls that need cutting and patching.
- Existing wiring type. Modern homes use copper NM cable (Romex). Aluminum wiring (1960s–1970s) and knob-and-tube (pre-1940s) both require complete removal and replacement, and many insurers refuse coverage until they are gone.
- Panel capacity. Adding circuits to a full panel means upgrading it first. A 100-amp panel cannot support central air, electric ranges, EV chargers, and home offices at once; upgrading to 200-amp service adds $1,000 to $3,000 — our electrical panel upgrade cost guide covers it in detail. A Federal Pacific or Zinsco panel (both flagged as fire hazards by the Consumer Product Safety Commission) needs urgent replacement.
- Permits and inspections. Significant electrical work requires a permit in most jurisdictions — typically $50 to $350, passed through to you. Unpermitted work can void your insurance and becomes a deal-breaker when you sell.
- Number of circuits. Each added circuit costs $150 to $500. A modern home needs 15 to 20; homes wired with 6 to 8 cannot power today’s appliances without overloading.

Common Electrical Projects and What They Cost
Not every job means rewiring the whole home. Common residential projects:
- Adding a dedicated circuit ($150–$500). New appliances, home offices, and bathroom heaters often need their own 15- or 20-amp circuit — 2 to 4 hours if panel capacity is available. If the panel is full, add the upgrade cost.
- Panel upgrade ($1,000–$3,000). Upgrading from 100A to 200A service is the most common upgrade for older homes — a full-day job replacing the main breaker panel and meter base, with a power shutoff and final inspection.
- Whole-home rewiring ($3,500–$15,000+). The biggest electrical investment a homeowner makes. With knob-and-tube or aluminum wiring, most insurers require rewiring before issuing a policy, and no lender will finance an active knob-and-tube home.
- EV charger installation ($400–$1,200). A Level 2 home charger (240V, 32–50 amp) is increasingly standard; cost depends on panel capacity and the run to the garage. Tax credits may offset part of it — confirm current programs with a tax professional, since incentives change.
- Smart home electrical prep ($500–$3,000). Dedicated circuits for smart panels and pre-wired switch locations are a growing category as homes modernize.
Warning Signs Your Home Needs Rewiring
Electrical problems develop gradually. Catching them early prevents both fire risk and expensive emergency repairs.
- Flickering or dimming lights when appliances start. The circuit is sharing load with a high-draw appliance; in older homes the panel is often near capacity. A dedicated circuit ($150–$500) usually resolves it.
- Frequent breaker trips. Repeated trips mean the circuit is overloaded or the breaker is failing — and a failing breaker that does not trip is a fire waiting to happen.
- Burning smell or discolored outlets. Stop using that circuit immediately. Discoloration indicates arcing or overheating — a serious fire hazard that warrants same-day service.
- Two-prong outlets throughout the home. They mean the wiring lacks a ground conductor, standard before 1960. Surge protectors do not function and shock risk is much higher; a rewire or GFCI retrofit is needed.
- Original wiring in a home built before 1970. After 55+ years the insulation has degraded, connections have loosened, and the system was built for a fraction of modern loads. An electrical inspection ($100–$250) should be a priority.
How to Get an Accurate Electrical Quote
Quotes for the same project can differ by $500 to $2,000 or more. The process:
- Get at least 3 written quotes. Each should itemize labor, materials, permits, and timeline. A single lump number with no breakdown is a reason to ask for itemization or move on.
- Verify licensing before discussing price. Check your state’s contractor licensing board first. An unlicensed pro who charges 30% less creates liability that far exceeds the savings.
- Confirm permit responsibility. The electrician should pull all permits and schedule inspections; “skip the permit to save money” is a red flag.
- Ask about warranty. Most reputable electricians warranty their work for 1 to 2 years; materials carry 10- to 25-year manufacturer warranties. Get both in writing.
- Check insurance. Require proof of general liability and workers’ compensation coverage — if an uninsured electrician is hurt on your property, you may be financially liable.
How to Spot an Electrical Quote Trap
Electrical bids vary 30–50% between contractors for the same project. A few patterns separate a fair price from a costly mistake:
- The suspiciously low bid. A quote 40% below the others usually means the electrician is unlicensed, skipping permits, or planning mid-project change orders. It is rarely the best value.
- “Skip the permit to save money.” Unpermitted work can void your insurance, fail inspection, and hide fire hazards. Wiring requires permits in every US jurisdiction.
- No wall-repair line. On a rewire in a finished home, electricians cut access holes to run cable. Budget an extra 10–20% for drywall patching and paint — a quote that ignores it is not the full price.
- Lead-fee markup. Angi, Thumbtack, and HomeAdvisor charge electricians per lead, and that cost is baked into your quote. On a marketplace with $0 lead fees, verified electricians bid directly and payment is held in escrow until you approve the work.
Frequently Asked Questions
How much does it cost to rewire a house?
A whole-home rewire runs $3,500 to $8,000 for a home under 1,500 square feet and $8,000 to $15,000 or more for a home over 2,500 square feet. The price depends on accessibility, existing wiring condition, and whether the panel also needs upgrading.
Can I do electrical wiring myself?
In most states, homeowners can legally do minor electrical work on their own home with a permit, such as replacing outlets, switches, and light fixtures. Any work involving the service panel or new circuits must be done by a licensed electrician. DIY electrical mistakes are a leading cause of house fires.
How long does whole-home rewiring take?
A home under 1,500 square feet takes 3 to 5 days; a home over 2,500 square feet takes 5 to 10 days. Multi-story layouts or hazardous legacy wiring take longer, and power is intermittently disconnected during the work.
How do I know if my house needs rewiring?
Key indicators include frequent breaker trips, flickering lights when appliances start, two-prong outlets throughout the home, original wiring in a home built before 1970, and burning smells or discolored outlet covers. Any of these warrants a professional electrical inspection, which typically costs $100 to $250.
Is electrical work covered by homeowners insurance?
Homeowners insurance typically covers sudden, accidental electrical damage such as a lightning strike or power surge. It does not cover gradual deterioration, unpermitted wiring, or upgrades needed because the system is outdated. Using a licensed electrician who pulls permits protects your coverage standing.
How do I compare electrician quotes fairly?
Request itemized quotes that break out labor, materials, permits, and timeline separately, and compare the scope of work rather than the bottom-line number. Get at least three written quotes, verify each license through your state board, and confirm general liability and workers’ compensation coverage before scheduling.
