Wiring & Breaker Boxes
Safe, Modern Wiring and Panels
Your home's wiring and electrical panel are the backbone of everything that runs on power, and when they're outdated or overloaded, they're a genuine fire and safety risk. Rewiring or upgrading a panel brings your electrical system up to modern demands and code.
This is serious, licensed work. A good electrician assesses your system's capacity and condition, then upgrades the panel or rewires safely and to code, handling permits and inspection. Older homes especially often need more capacity than their original wiring provides.

Did You Know?
Outdated wiring and overloaded electrical panels are a leading cause of house fires, which is why upgrading an aging system is a safety priority, not just a convenience.
Wiring & Breaker Boxes Cost. How Much Do Projects Cost?
Most projects run between $1,500 and $30,000. The average price is typically around $2,500. The $1,500 to $30,000 range covers the two jobs this service is usually hired for: a panel upgrade, which averages around $2,500, and a whole-home rewire, which averages around $15,000 and swings on whether the electrician can work through the attic and joists or has to open walls. Smaller wiring work sits below the range - a dedicated circuit is $250 to $900 and a single outlet, switch, or fixture $100 to $300 or more - and knob-and-tube replacement can reach $40,000, above it. Two large lines are usually quoted separately and are the ones that surprise people: drywall and plaster repair after a rewire, which adds 20 to 30 percent to the labor, and the municipal permit and inspection fee, which goes to the city rather than to your electrician.
Typical duration: 1 day to 2 weeks
| Cost Factor | Typical Range | Notes |
|---|---|---|
| Small wiring work | $250-$900 per dedicated circuit | A single outlet, switch, or fixture is a flat $100-$300+ per opening, and electricians bill $50-$130 per hour, so this work never approaches the floor of the range above |
| Panel (breaker box) upgrade | $1,300-$4,500 installed | A 200-amp panel is $250-$350 in parts, so nearly all of the price is labor, load calculation, grounding and bonding, permit, and utility coordination; a job that also moves the meter, service entrance, or panel lands at $2,500-$4,500+ |
| Partial rewire, one room | $600-$2,500 | A kitchen with its dedicated appliance circuits runs $1,500-$4,000; rewiring room by room costs more per square foot than doing the whole house at once because setup, access, and permits repeat |
| Partial rewire, one to two floors | $3,000-$10,000 | If you are planning three partials in sequence, price a whole-home rewire against them first |
| Whole-home rewire | $10,000-$30,000 installed, or $5-$17 per sq ft | $10,000-$20,000 where the electrician can work through the attic, basement, and joists, and $20,000-$30,000+ where walls have to be opened; $12,000-$18,000 is typical for a mid-size house and high-cost metros reach $25,000-$50,000+ |
| Drywall and plaster repair after rewiring | $300-$1,500+ per patch | Almost always excluded from the rewire quote and adds 20-30% to the labor; replacing full walls or ceilings runs $2-$6 per sq ft |
| Knob-and-tube or aluminum wiring | $8,000-$40,000 | Aluminum remediation runs $8,000-$20,000 and knob-and-tube replacement $12,000-$40,000, because the old wiring has to come out rather than be abandoned in the walls |
| Permit and municipal inspection | $75-$1,500 per permit | Paid to the jurisdiction rather than to the electrician, and triggered by both a panel upgrade and a rewire - San Diego posts $176.57 for a panel replace or upgrade up to 200 amp |

Signs You Need Wiring & Breaker Boxes
- Frequently tripping breakers
- Flickering or dimming lights
- An old fuse box or undersized panel
- Aging or hazardous wiring (knob-and-tube, aluminum)
- Adding major appliances or an addition
Is It Right For You?
Who It's For
- Homeowners with outdated or overloaded electrical systems
- Anyone upgrading capacity for modern demands
Who It's Not For
- Single fixture or outlet work handled directly
- Newer homes with adequate, sound wiring
What to Watch Out For
It involves opening walls and significant work
Hidden wiring issues can expand the scope
Alternatives to Consider
| Alternative | Better When | Worse When |
|---|---|---|
| Panel upgrade only | Cheaper than a full rewire | Doesn't address aging wiring itself |
| Adding a subpanel | Adds capacity for a specific area | Not a fix for hazardous whole-home wiring |
Is It Worth It?
Rewiring or a panel upgrade is worth it, and often essential, for safety and modern capacity, especially in older homes with aging or overloaded systems.
Questions to Ask Your Pro
- Does my panel have enough capacity for my needs?
- Is my wiring safe, or does it need replacing?
- Will you handle permits and inspection?
Frequently Asked Questions
A panel upgrade runs $1,300 to $4,500 installed and averages about $2,500. Partial rewiring runs $600 to $2,500 for a single room and $3,000 to $10,000 for one or two floors, and a whole-home rewire runs $10,000 to $30,000, averaging about $15,000. Drywall repair is usually excluded from the quote and adds 20 to 30 percent to the labor.
Consider an upgrade if you have an old fuse box, frequently tripping breakers, or are adding major appliances or an addition that needs more capacity.
Warning signs include flickering lights, tripping breakers, burning smells, and outdated systems like knob-and-tube or aluminum wiring. Replacing knob-and-tube runs $12,000 to $40,000 and remediating aluminum branch circuits $8,000 to $20,000.
Wiring and panel work is a serious fire and shock hazard, so it requires a licensed electrician working to code with proper permits and inspection. The permit and municipal inspection fee runs $75 to $1,500 and is paid to the jurisdiction, not to the electrician.
A panel upgrade may take a day, while a whole-home rewire can take one to two weeks depending on the home's size.
