Electrical Rewiring Cost 2026: Signs, Safety, and Fixes
Electrical rewiring is the repair nobody wants and every old building eventually needs. Wiring does not last forever, and the stuff behind the walls of a mid-century house or an aging commercial space was never designed for the load a modern building puts on it. The stakes here are not cosmetic. Faulty wiring is a leading cause of structure fires, so the warning signs are worth taking seriously the first time, not the third. The good news is that a rewire is planned work with a known cost, as long as you catch it before it forces the issue.
Short answer: A full electrical rewire runs $3 to $9 per square foot in 2026, with older or hard-to-access buildings higher, and a panel upgrade adds $1,500 to $4,000. The Handy Geeks handles rewiring and panel work through licensed electricians across its four markets. Flickering lights, warm outlets, and breakers that trip repeatedly are the signs not to ignore.
Rewiring sits at the serious end of the trade, well inside licensed electrical work, and never a do-it-yourself job.
How Much Does Electrical Rewiring Cost in 2026?
A whole-building rewire runs $3 to $9 per square foot for labor and materials, per Angi and HomeGuide data, and it climbs toward $30 in old buildings where walls have to be opened and access is bad. Rewiring is usually quoted after a walkthrough for that reason. A panel is priced separately: a replacement runs $850 to $2,500, and an upgrade to 200 amps, which most modern buildings need, runs $1,500 to $4,000 including the panel, breakers, labor, and permit.
| Job | The Handy Geeks 2026 Range | What Moves It |
|---|---|---|
| Whole-building rewire | $3 to $9 per sq ft | Age, access, and wall finishes |
| Partial rewire or single circuit | Quoted per circuit | Run length and access |
| Panel replacement | $850 to $2,500 | Panel size and location |
| Upgrade to 200 amps | $1,500 to $4,000 | Panel, breakers, permit, and labor |
| Add a GFCI or dedicated outlet | $130 to $300 | Location and code retrofit |
Read one row and you have a planning number, though the real quote comes after a walkthrough. A rewire is a budget item, so it belongs in your planned property budget rather than an emergency.
What Are the Signs a Building Needs Rewiring?
Your building will usually tell you before it fails. Lights that flicker or dim when an appliance kicks on, outlets or switch plates that feel warm or look discolored, a faint burning smell near an outlet, breakers that trip on the same circuit again and again, two-prong ungrounded outlets throughout, and any buzzing from the panel all point the same direction. A single one might be a loose connection. Several together mean the system is overloaded or degraded, and that is a call to make now.
Aluminum, Knob-and-Tube: What Has to Go?
Two kinds of old wiring are worth naming, because insurers and inspectors flag both. Knob-and-tube, common before the 1950s, has no ground and its insulation crumbles with age, so it is a real fire and shock risk in a building drawing modern loads. Aluminum branch wiring from the 1960s and 70s expands and loosens at connections, which is where it overheats. Neither always needs a full tear-out, but both need a licensed electrician to assess, and both are exactly the situations where a rewire or a remediation earns its cost.
Do You Need a Panel Upgrade Too?
Often, yes, and it is a separate decision from the wiring. An old 60 or 100-amp panel cannot safely feed a modern building full of HVAC, EV charging, and equipment, so a rewire is a natural moment to move to 200 amps. A panel that is a known fire hazard, some older brands are, should be replaced on its own regardless. Getting the wiring and the panel done together saves opening things up twice, and it is the kind of job where knowing what to leave to a pro is not really a question.

Frequently Asked Questions
How Much Does Electrical Rewiring Cost in 2026?
A full rewire runs $3 to $9 per square foot, higher in old or hard-to-access buildings. A panel replacement is $850 to $2,500, and an upgrade to 200 amps runs $1,500 to $4,000 with permit and labor.
What Are the Warning Signs of Bad Wiring?
Flickering lights, warm or discolored outlets, a burning smell, breakers that trip repeatedly, two-prong ungrounded outlets, and buzzing from the panel. Several of these together mean the system needs attention now.
Is Knob-and-Tube or Aluminum Wiring Dangerous?
Both are flagged by insurers and inspectors. Knob-and-tube has no ground and crumbling insulation, and aluminum loosens and overheats at connections. Both need a licensed electrician to assess and often remediate.
Do I Need a Panel Upgrade With a Rewire?
Often. An old 60 or 100-amp panel cannot safely feed a modern building, so a rewire is a natural time to move to 200 amps. A known fire-hazard panel should be replaced regardless.
Can I Do Electrical Rewiring Myself?
No. Rewiring carries serious shock and fire risk and requires a permit and a licensed electrician. It is firmly on the professional side of the line, no exceptions.
How Long Does Rewiring Take?
It depends on size and access, from a few days for a partial job to a week or more for a full building. Open walls speed it up; finished walls that must be opened and patched slow it down.
Towns We Serve
We handle electrical rewiring across four markets. In Southern California that covers Los Angeles, Long Beach, Pasadena, Calabasas, and the San Fernando Valley towns of Woodland Hills, Canoga Park, West Hills, and Topanga, plus Orange County and San Diego. In Northern California we work San Francisco, Oakland, Berkeley, and Sacramento, and we also cover the Phoenix and Scottsdale metro and the Las Vegas valley, where older housing stock runs oldest.
Last Word On It
Electrical rewiring is planned safety work that too many buildings put off until the breaker panel forces it. Watch for the warm outlets and the repeat trips, get an old system assessed by a licensed electrician, and do the wiring and the panel together when it makes sense. Handle it on your schedule and it stays a budget line instead of an emergency.
Anyway. Tell us the building when you are ready. Call or text +1 818-835-0556, or reach us here and we will walk it.
