  11. Squeaky Floors: Although not always related to foundation issues, squeaky floors can be concerning in conjunction with other signs.

Types of Foundation Cracks

Our Charlotte, NC realtors say that a homeowner or prospective buyer should be aware of several indicators pointing to a potential foundation problem or concern. Look for the following things around your house: Understanding the different types of foundation cracks is crucial for evaluating the severity of the issue:

  1. Structural Cracks: These are typically at least 1/4 inch wide and can make the foundation wall feel uneven. Structural cracks are severe and may require the expertise of an engineer to repair.
  2. Horizontal Foundation Cracks: Horizontal cracks are particularly concerning, as they result from the constant expansion and contraction of the soil, often due to clay content. These cracks can exert significant pressure on your basement walls and may lead to bowing.
  3. Wall Cracks Near Your Foundation: Wall cracks near the foundation can result from various factors, including poor construction, water damage, or settlement. Repair may involve sealants, epoxy injections, hydraulic cement, and improved drainage.
  4. Floor Cracks: Foundation floor cracks are typically caused by building settling, poor surface drainage, or leaks seeping through the floor. In such cases, a thorough examination of pumps, weeping tiles, and drainage systems is essential.

How to Address Foundation Cracks

When you notice foundation cracks, taking the right steps to address the issue is crucial:

  1. Monitor the Situation: Observe the broader picture and track whether the cracks are increasing in size or number over six months to a year.
  2. Identify Patterns: Pay attention to patterns. If multiple issues are concentrated in one location, such as the living room or the back of the house, it could indicate a more significant problem.
  3. Observe Movement and Patterns: Focus on movement and crack patterns. If you notice several doors opening or closing independently, it’s a cause for concern.
  4. Geotechnical Considerations: Be aware that geotechnical issues, like slope creep, can be challenging to address. Additionally, drainage problems, although highly damaging to your foundation, are often simpler and less expensive to fix.

The Takeaway

If you suspect foundation issues, it’s crucial to seek professional guidance. General contractors, house inspectors, foundation engineers, geotechnical engineers, and structural engineers are the experts to contact for a thorough assessment and potential solutions.

In conclusion, not all foundation cracks are cause for alarm, but vigilance and an understanding of warning signs are vital for the long-term stability of your home.
