Look for sloping floors (roll a marble), sticking doors or windows that don’t close properly, diagonal cracks at window corners or door frames, gaps where baseboards pull away from walls, and visible cracking in exposed foundation. Some movement is normal in older homes and completely manageable. Significant, uneven, or progressive shifting may require structural evaluation. I help buyers spot early signs during tours and coordinate with engineers when a closer look is warranted so the analysis reflects severity and realistic repair cost.
