Early detection is essential in preventing further damage. This guide will highlight key areas to inspect for cracks, including your basement and garage, and specific signs to look for, empowering you to safeguard your home effectively.

Common Areas to Inspect for Foundation Cracks

When it comes to foundation cracks, knowing where to look can save you a lot of trouble. Regular checks can help you catch problems early and avoid costly repairs down the track.

Walk around your home’s base.

  • Check corners and wall joints

Garage

Cracks may form where the  floor meets the walls.

  • Look for diagonal cracks in the floor
  • Check the walls near the garage door

Identifying Warning Signs of Foundation Damage

Once you’ve inspected common areas for cracks, it’s important to be aware of other potential indicators of foundation issues. Early detection can help prevent more serious structural damage.

Interior Warning Signs

Keep an eye on the following features inside your home:

  • Doors and windows: If they stick or don’t open smoothly, it could mean your foundation is shifting.
  • Gaps between walls and ceilings or floors: These separations often signal movement in the structure.

  • Moisture or mold in the basement or crawl space: Persistent dampness can weaken the foundation over time.

Exterior Warning Signs

Outside the home, look for:
