Diagonal wall cracks often indicate structural stress caused by foundation issues.

What Causes Diagonal Cracks?

Diagonal cracks are a common sign of foundation settlement or shifting. As one section of your foundation sinks or moves independently, the wall above it begins to tear in a diagonal pattern. Causes may include:
