Foundation Issues: What's Normal vs. What's a Red Flag

When buying or selling a home, noticing cracks or uneven surfaces can raise concerns about the foundation. However, not all imperfections are cause for alarm. Some are normal due to a home's natural settling over time, while others indicate serious structural problems.

Common Imperfections (Usually Normal)

These minor flaws are typical in many homes and don't necessarily indicate major foundation problems:

Hairline Cracks

Small cracks less than 1/8” wide in drywall or concrete are common as homes naturally settle. These often appear near:

• Doors and windows
• Along foundation slabs
• Corners of rooms

Surface-Level Concrete Cracks

Thin cracks in driveways, sidewalks, or garage floors are typically normal due to:

• Weather changes
• Natural concrete shrinkage
• Temperature fluctuations

Subtle Foundation Settling Signs

In homes with raised foundations, minor signs of settling include:

• Slight floor unevenness
• Small gaps between baseboards and floors
• Occasional door or window sticking

Red Flags (Serious Foundation Problems)

These warning signs suggest significant structural issues that require professional evaluation:

Structural Crack Indicators

• Cracks wider than 1/4 inch
• Expanding or growing cracks
• Stair-step patterns in brick or drywall
• Vertical or horizontal foundation wall cracks

Significant Structural Movement

• Noticeably uneven or sloping floors
• Doors or windows that won't close properly
• Large, uneven gaps around window and door frames
• Visible separation between walls, ceilings, or floors

Water-Related Concerns

• Water intrusion through foundation cracks
• Moisture damage near foundation areas
• Unexplained dampness in basement or crawl spaces
