Cost planning
Plan for the service scope, not the symptom alone
The symptom alone does not set the price. Use the national electrical repair ranges below to compare the likely service scope, then ask what testing, parts, permits, access, restoration, and follow-up are included in the written quote.
Minor or limited scope
$150-$425
A single outlet, switch, or simple fix; the quote should confirm access, testing, materials, and exclusions.
Typical project scope
$350-$1,100
Tracing a fault or fixing several devices on a circuit
Complex project scope
$1,000-$4,200
Work involving wiring runs or the panel; the quote should confirm access, testing, materials, and exclusions.
Major or combined scope
Project-specific quote
A broader electrical repair project that combines multiple scope decisions, requires added electrical capacity, or reveals related system work after evaluation.
A written quote should state the diagnostic work, repair scope, equipment, permit or inspection responsibility, restoration, and change-order process that apply to the property.
