Behind the Wall: The Hidden Causes of Drywall Cracks 

It started with a sound that you randomly heard. Much like the chirp from your smoke detector that needs new batteries, you hear it but ignore it. The difference between your drywall and your smoke detector is eventually the chirping will stop. When you’re faced with a foundation issue, the sounds of the settlement will continue until something gives. Drywall cracks are your first indication that something isn’t right with your home’s situation. The good news is that drywall cracks can give you clues to what's happening so you can resolve it before it gets worse. In this article, we will discuss drywall cracks and what problems are most likely associated with them. 

Understanding the Causes of Drywall Cracks 

Drywall cracks are a common issue faced by homeowners and can be a cause for concern. They can appear in various forms and locations, each hinting at different underlying issues. Addressing these cracks promptly is essential to maintaining the structural integrity and aesthetic appeal of your home. In this blog, we will discuss the 3 main reasons for drywall cracks and offer insights into preventing and repairing them effectively. 

Foundation Settlement and Shifting 

One of the most significant causes of drywall cracks is the settling and shifting of a home's foundation. Over time, the soil beneath a house can compact, causing the foundation to settle unevenly. This movement can lead to stress on the walls, resulting in cracks. Foundation Settlement can happen due to different reasons. One reason is Soil Composition. Expansive clay soils, common in many regions, can expand and contract with moisture changes, exacerbating foundation movement. Tree Roots are another cause of Foundation issues. Large trees near a home can absorb significant amounts of water, leading to soil shrinkage and subsequent foundation settling. 

Temperature and Humidity Fluctuations 

Changes in temperature and humidity levels can cause the materials in your home to expand and contract. Drywall, wood framing, and other materials all respond to these environmental changes, which can lead to cracking. Seasonal Changes can be problematic due to freeze-thaw cycles as well as extreme heat. Homes in areas with significant seasonal temperature variations are more prone to drywall cracks. 

Moisture Levels due to rainfall, humidity, or even a plumbing issue can affect the soil and lead to soil heave which will affect drywall. High humidity can cause the drywall to swell, while low humidity can cause it to shrink, leading to potential cracking. 

Poor Construction Practices 

The quality of the initial construction plays a crucial role in the longevity and durability of your drywall. Poor construction practices can lead to cracks appearing sooner and more frequently. Improper Installation can contribute to drywall failure over time. Incorrectly installed drywall or insufficiently secured joints can lead to premature cracking. 

Subpar Materials used by contractors who want to save money and cut corners will quickly affect the stability of the drywall in a home. Using low-quality materials can compromise the integrity of the drywall, making it more susceptible to damage. 

Natural Aging of Materials 

All materials have a lifespan, and as they age, they can deteriorate and become more prone to damage. Drywall is no exception. 

Over time, even well-installed and maintained drywall can develop cracks due to natural aging. Also known as wear and tear. The repeated stress from everyday activities can weaken drywall, leading to cracks.
