Can residential electrical services truly prevent unexpected hazards at home?

A friend recently noticed sparks and frequent breaker trips in her home. She called Houston One Stop Home Solutions for residential electrical services, and their team quickly identified faulty wiring and outdated outlets. Seeing the repairs made me wonder how often do homeowners overlook potential electrical issues until they become serious problems? Have you ever relied on professional residential electrical services to maintain safety and efficiency in your home? Do you think regular checkups are enough, or should electrical systems be updated more proactively?
