How do I know if my concrete steps are sinking or just built incorrectly?

Sinking steps typically show a gap between the top riser and the door threshold, separation between the stoop slab and the foundation wall, or a visible tilt. Steps built incorrectly show consistent slope with no gap at the foundation. A Scaldino technician will probe beneath the stoop to confirm whether void formation is present, which is the definitive indicator of settlement.
