Understanding Different Types of Cracks

Before diving into the repair process, it's crucial to identify the type of cracks you're dealing with. Different cracks need different approaches, which will save you time and money.

Hairline Cracks

Hairline cracks are thin and shallow. They typically appear in plaster or drywall due to minor settling or slight humidity changes. Although they don't usually indicate structural issues, they can be unsightly.

Vertical Cracks

Vertical cracks are common in walls and foundations and often result from normal settling. These cracks are generally not severe unless they extend through multiple bricks or blocks.

Horizontal Cracks

Horizontal cracks can be more concerning as they may indicate pressure from soil or water against the foundation. These require more immediate and thorough attention.

Diagonal Cracks

Diagonal cracks could signal foundational shifts or issues related to settling and should be assessed carefully. Depending on the crack size and direction, they might need professional evaluation.
