How do I know if my foundation is settling and needs underpinning?

Clear signs of foundation settlement include diagonal cracks radiating from window and door corners, sticking interior doors, visible gaps between baseboards and floors, sloped finished floors detectable with a marble test, and separation of chimney or porch from the main structure.

A single crack is not conclusive. Patterns across multiple walls, progression over months, and measurable tilt are what confirm active settlement. A structural assessment quantifies it before recommending underpinning.
