What Are Foundation Cracks?
Foundation cracks are visible breaks or separations in the concrete or masonry that make up a home’s foundation. They can occur due to settling, pressure changes, moisture infiltration, or improper construction.
Types of Foundation Cracks
The type of foundation crack can help determine the potential cause and severity. Here are common crack types:
| Crack Type | Characteristics |
|---|---|
| Vertical Cracks | Thin, straight cracks—often due to settling |
| Horizontal Cracks | Often caused by pressure on foundation walls |
| Diagonal Cracks | Likely due to uneven settling or soil pressure |
| Stair-Step Cracks | Found in block walls—indicate severe structural issues |
Recognizing the type of crack is the first step in assessing foundation health.

How to Identify Foundation Cracks
To accurately identify foundation cracks:
- Inspect Indoors and Outdoors: Check basement walls, foundation slabs, exterior walls, and floors.
- Measure Crack Width and Length: Use a ruler to document changes over time; cracks wider than ¼ inch require attention.
- Note Crack Direction: Vertical cracks are less severe than horizontal or stair-step patterns.
- Monitor Damage Signs: Look for uneven floors, sticking doors/windows, and water infiltration.
Assessing the Severity of Foundation Cracks
Severity depends on the crack type, size, and surrounding symptoms. Small vertical hairline cracks are typically harmless, but wide, growing, or moisture-filled cracks may indicate significant structural damage.
Foundation Damage Signs to Watch For:
- Uneven Floors: May signal underlying shifting or settling.
- Bulging Walls: A severe sign of pressure buildup.
- Watermarks or Mold: Cracks allowing water infiltration.
- Doors/Windows Misalignment: Impacts usability and structure stability.
