Problems: Fire; electrocution.
Trouble signs: Flickering or dim lights (especially when portable appliances are used); circuit breakers that frequently trip; outlets that are hot to the touch.
What you can do: Ensure lightbulbs aren't loose and, if you're handy, replace two-pronged or hot outlets. Flip each circuit breaker at least once a year to prevent corrosion. If problems continue, call in a licensed electrician.
What it may cost: $2 per three-pronged outlet. $300 to $500 for an electrical inspection and basic repairs. Replacing a medium-sized home's faulty wiring typically costs $4,000 or more.
What you can save: Your life and home.
