Are Wall Cracks a Foundation Problem?

Discovering a crack in the walls of your home can be unsettling. It’s easy to jump to the conclusion that any crack is a dire sign of foundational damage. However, not all wall cracks spell trouble for your home’s structure. 

This resource page will help you determine whether or not wall cracks you may be seeing are the telltale sign of a foundation problem or something less serious. If you’re in doubt, schedule a free consultation Foundation Support Specialists today. 

Understanding Wall Cracks

Wall cracks are often indicators of foundation movement, but it’s crucial to understand that not all movement leads to structural damage. A foundation might shift slightly, causing cracks without compromising the integrity of your home’s structure. So, if you’re worried about a crack in your wall, there’s a chance it might not be as serious as you think.

What Causes Wall Cracks?

Several factors can lead to wall cracks, including:

  • Expansive soil
  • Vibration from nearby activities
  • Drainage issues
  • Seismic activity
  • Severe weather events

While some cracks result from these conditions and don’t indicate serious problems, others, especially those stemming from structural damage, are more concerning. The good news is, with professional assessment, even these serious issues can be resolved.

Types of Wall Cracks

Wall cracks can manifest in various forms, both inside and outside your home. They include:

  • Drywall cracks
  • Vertical and horizontal wall cracks
  • Stair-step cracks in brickwork
  • Bowed walls with cracks
  • Cracks in stucco
  • Separation cracks between walls and ceilings or floors

Recognizing the type of crack can provide clues about its seriousness and whether it points to foundational issues.

Identifying Serious Wall Cracks

While movement in the foundation can cause benign wall cracks, some cracks are unmistakable signs of structural damage. Here are the red flags to watch for:

  • Cracks spanning walls, ceilings, or floors
  • Horizontal cracks running the length of a wall, particularly with bowing
  • Stairstep cracks in masonry
  • Displaced or cracked moldings
  • Cracks running from door or window corners towards the ceiling
  • Significant gaps between walls and ceilings or floors

Though small, hairline cracks are often not a cause for concern, larger cracks — whether in width or length — typically signal structural damage needing professional repair.
