What’s Going On With Wall Cracks?

Types of Wall Cracks

• Horizontal Cracks: These can be serious and might mean there’s a problem with the foundation.
• Vertical Cracks: These are common and usually happen because the house is settling. They’re often not a big deal.
• Diagonal Cracks: These can happen if the house settles unevenly or if there are structural shifts.

Why Do Wall Cracks Happen?

• Settling Foundations: Houses naturally settle over time, which can cause cracks.
• Moisture Issues: Leaks or high humidity can make walls weaker.

• Poor Construction: Using cheap materials or bad building methods can cause cracks.

Serious Trouble Signs
