How do I evaluate a home's structural integrity?

Short Answer

A thorough home inspection by a licensed professional is the best way to evaluate a home's structural integrity. Look for visible signs of foundation issues, including cracks in the walls or foundation, sloping floors, doors that stick, and gaps around windows. Check for signs of water damage, termite damage, and previous repairs. In South Jersey, pay attention to the basement or crawlspace for moisture and foundation movement.

Evaluating a home's structural integrity requires a trained eye, but you can look for warning signs during a tour. Check the foundation for cracks, especially horizontal or stair-step cracks in concrete block walls. Look at the walls and ceilings for cracks, especially around door and window frames. Open and close doors and windows. If they stick or do not close properly, it may indicate foundation movement. Check the floors for sloping or sagging. A marble placed on the floor should not roll. Look for gaps between the walls and the ceiling or floor. In the basement or crawlspace, look for signs of water intrusion, musty odors, mold, or efflorescence (white mineral deposits on the walls). Check for signs of previous repairs, like patched cracks or reinforced areas. A professional home inspector will evaluate the foundation, framing, roof structure, and load-bearing walls. If the inspector has concerns, they may recommend a structural engineer for a more detailed evaluation. Do not skip this step, especially for older homes in South Jersey.
