Electrical Maintenance Costs & Schedule
Homeowners can handle detector tests and visual checks; panel and wiring work should stay with licensed electricians.
Direct answer
Test smoke and CO detectors monthly, exercise GFCIs periodically, and call a pro for warm outlets, burning smells, or frequent breaker trips. Annual DIY upkeep is inexpensive; panel work is a separate project budget.
