Some of the most common signs of foundation issues include:
1. Cracks in walls, ceilings or floors
2. Doors and windows that stick or won't close properly
3. Uneven or sloping floors
4. Gaps between walls and ceilings
5. Bowing or leaning basement walls
6. Water intrusion or moisture issues in the basement
If you notice any of these issues, it's best to schedule a professional inspection before the problem worsens.
