Foundation cracks are a common concern for homeowners. When cracks appear in your home’s foundation, it’s easy to panic and assume the worst. However, not all foundation cracks signal a serious issue. Many cracks are harmless and may simply be a normal part of the settling process. Understanding the different types of foundation cracks and their causes can help homeowners determine when to worry and when to relax. With this in mind, we at Duratech Texas why foundation cracks aren’t always a sign of a serious problem.

Types of Foundation Cracks

There are two primary types of foundation cracks: hairline cracks and structural cracks. Hairline cracks are typically thin and narrow, often measuring less than 1/8 of an inch. These cracks are very common and are usually not a sign of a serious problem. In most cases, hairline cracks are the result of natural settling that occurs as a house adjusts to its environment. Over time, the soil beneath the foundation may shift or compact, causing minor movement. This is generally a normal process and doesn’t require immediate attention. On the other hand, structural cracks are larger, wider, and may be accompanied by other signs of foundation issues, such as sloping floors or doors and windows that don’t open and close properly. Structural cracks can be caused by various factors, including moisture changes, soil instability, or significant settling. These cracks may indicate a more serious problem that could require professional foundation repair.

Common Causes of Foundation Cracks

1) Natural Settlement. As a home settles into the ground, small cracks may develop in the foundation. This is completely normal, especially in new homes or homes built on soils that are prone to shifting. The weight of the house can cause slight settling over time, leading to minor cracks. These cracks rarely affect the integrity of the structure and can often be repaired with simple patching techniques.
2) Soil Moisture Fluctuations. Changes in moisture levels in the soil beneath your foundation can also contribute to the formation of cracks. Dry weather can cause the soil to shrink, while excessive moisture can lead to soil expansion. Both conditions can result in movement and minor cracking in the foundation. This type of cracking is usually not severe and can be addressed by managing moisture levels around the foundation, such as installing proper drainage systems.
3) Temperature Changes. Extreme temperature fluctuations can cause materials in the foundation, such as concrete, to expand and contract. This thermal movement may lead to small, surface-level cracks. As with soil moisture fluctuations, these cracks are typically not a cause for concern unless they become larger or more pronounced over time.
4) Minor Shifts in the Foundation. Foundations are designed to move slightly as part of the natural settling process. A small shift in the foundation may result in cracks, but this is not necessarily a sign of impending structural failure. Often, these shifts are minor and don’t compromise the overall stability of the home.

When to Worry About Foundation Cracks

While many foundation cracks are harmless, some cracks can be a sign of serious issues. If the cracks are large (wider than 1/4 inch), grow over time, or are accompanied by other signs of structural problems (such as uneven floors, gaps around doors and windows, or water in the basement), it’s time to call in a professional. A structural engineer or foundation repair expert can assess the severity of the damage and recommend the appropriate course of action.
