North Carolina Home Inspector Practice Exam

When are cracks in walls usually a concern for home inspectors?

1. When they are less than 1 inch wide

2. Only when they show signs of displacement

3. When they are horizontal

4. When they occur in corners

The correct answer is: Only when they show signs of displacement

Cracks that show signs of displacement are considered a significant concern for home inspectors because they often indicate structural issues that could compromise the integrity of the building. Displacement refers to movement where one side of the crack is higher or lower than the other, suggesting that there may be a problem with the foundation or a load-bearing element. Inspectors are trained to assess the severity and implications of these cracks, as they can lead to further damage and costly repairs if not addressed. While other types of cracks can also signal issues, those characterized by displacement often warrant further investigation to determine the underlying cause. This could involve looking at the foundation, the soil conditions, or the overall structural support of the home. Therefore, when assessing cracks in walls, home inspectors prioritize those with displacement due to the potential risk they represent to the overall stability of the property.
