Why Does Drywall Crack and How to Prevent

Why Does Drywall Crack

Drywall cracks can occur for several reasons, including foundation settlement, temperature fluctuations, humidity changes, and seismic activity.

New homes often experience settlement, especially if green lumber is used, resulting in small cracks in the drywall.

Water leaks can also cause cracks, along with yellowing, browning, and water saturation.

Leaving a vacant home for extended periods can lead to drywall cracks as well.

Climate changes, bad tape jobs during installation, and foundation issues are other factors that can cause drywall to crack.

It is crucial to address the root cause of the issue before fixing and repainting the drywall to prevent future cracking.

New Home Settlement And Drywall Cracks

Newly constructed homes often experience settlement, which is the process of the soil beneath the foundation compacting over time. This settling can cause small cracks in the drywall. One common reason for this settlement is the use of green lumber in the construction process. Green lumber, which is wood that has not been properly dried or seasoned, tends to shrink as it dries, resulting in minor movements and shifts within the structure of the home.

While these cracks may be concerning, they are typically cosmetic in nature and can be easily repaired. It is important to note that these cracks usually appear within the first year of the home being built. After this initial settling period, most cracks will stabilize, allowing for effective repairs to be made. It is recommended to wait until the first year of a new home has passed before addressing these cracks, as further settlement may occur during this time.

Water Leaks And Drywall Crack Damage

Water leaks within the walls of a home can cause significant damage to drywall, often resulting in cracks. When water penetrates the drywall, it can lead to yellowing, browning, and water saturation, weakening the integrity of the material. The source of the water leak should be identified and fixed before repairing the cracked drywall to prevent further damage.

Addressing water leaks promptly is crucial for preventing long-term damage. Water that continues to seep into the walls can lead to mold growth, further deterioration of the drywall, and potential structural issues. It is essential to investigate and repair any water leaks as soon as they are discovered to preserve the quality of the drywall and maintain the structural integrity of the home.

Vacant Homes And Drywall Cracks

Leaving a home vacant for extended periods of time can contribute to the formation of drywall cracks. When a house is unoccupied and unheated, the lack of temperature and humidity regulation can cause the drywall to shrink and contract. In areas with extreme climate changes, such as regions with cold winters and hot summers, this shrinkage and expansion can occur cyclically with the seasons, leading to stress on the wooden frame of the home and subsequent cracking of the drywall.

To prevent drywall cracks resulting from vacant homes, it is advisable to maintain a consistent temperature and humidity level within the property. This can be achieved through the use of programmable thermostats and humidifiers or dehumidifiers (depending on the specific climate conditions). By creating a stable environment, the risk of drywall cracks due to temperature and humidity fluctuations is significantly reduced.

• Maintain a consistent temperature and humidity level within the property.
• Use programmable thermostats to regulate temperature.
• Add humidifiers or dehumidifiers as needed to maintain appropriate humidity levels.

Note: Proper maintenance and climate control can help prevent drywall cracking in vacant homes.

Understanding The Causes Of Drywall Cracks

Drywall cracks are considered undesirable as they can detract from the aesthetics of a home. Several factors contribute to the development of these cracks, including:

• Climate changes: Variations in temperature and humidity can cause drywall to expand and contract. This cyclic movement places stress on the wooden frame of the home, transferring it to the drywall and potentially leading to cracks.

• Improper installation techniques: A poorly executed tape job during the installation process can result in cracks if the tape detaches from the drywall, taking some of the plastered mud with it.

• Foundation issues: Foundation settlement and heave also play a significant role in the formation of drywall cracks. Foundation settlement occurs when the soil beneath the foundation sinks or compresses, while foundation heave is when the soil pushes or lifts the foundation. These movements can create stress on the drywall, resulting in cracks.

To identify foundation issues, watch out for signs such as:

• Cracks thicker than a quarter-inch
• Cracks originating from door or window frames
• Stairstep cracks through the drywall
• Bulging and bowing of the drywall

It is crucial to address the root cause of the foundation issue before patching up and repainting the drywall to ensure long-term stability.

Preventing And Addressing Drywall Cracks

Preventing drywall cracks is vital to maintain the overall appearance and structural integrity of a home. Understanding the causes and taking proactive measures can help reduce the risk of cracks and prevent the need for extensive repairs.

To prevent drywall cracks, it is essential to address building movement, environmental factors, and installation errors. By considering the location of the crack (whether it is on the ceiling or walls), it becomes easier to identify the cause and find appropriate solutions. Regular maintenance and timely repairs, such as fixing water leaks and addressing foundation issues, can go a long way in preventing the development of drywall cracks.

Frequently Asked Questions

Is it normal for drywall to crack?

Drywall cracking can be considered somewhat common under certain circumstances. One of the main causes of drywall cracking is improper installation, which can lead to the material not being properly supported or secured. Additionally, changes in humidity and temperature can cause the drywall to expand and contract, resulting in cracks over time. While some cracking can be considered normal settling, it is important to differentiate between these cracks and those caused by structural damage, as the latter require immediate attention to prevent further issues.

How do you stop drywall from cracking?

To prevent drywall from cracking, it is essential to utilize suitable expansion joints. Vinyl expansion joints, such as the 093V Expansion Joint and the Hideaway Expansion Joint, are the most effective in this regard. Designed to resist denting and retain permanent flexibility, these joints significantly reduce wear-and-tear on the drywall, minimizing the need for frequent repairs and preventing cracks from forming.

Why does drywall crack on ceiling?

Drywall cracks on the ceiling can occur due to a variety of reasons, with normal wear and tear being one of the primary factors. As a building ages, foundation settling can cause natural shifting and movement, leading to cracks in the ceiling, walls, and floors. Another common cause of ceiling cracks is moisture damage. Excessive moisture can weaken the integrity of the drywall, causing it to expand and contract, resulting in cracks over time. Whether it’s due to gradual wear or moisture-related issues, understanding the underlying causes can help in effectively addressing and preventing these cracks from occurring.

Can humidity cause drywall to crack?

Yes, humidity can indeed cause drywall to crack. When there is high humidity in the home, moisture can accumulate in the studs behind the drywall, leading to the expansion and contraction of the wood. This constant shift in the framing can eventually cause the drywall to crack. Additionally, excessive moisture in the air can weaken the structural integrity of the drywall, making it more susceptible to damage.

Aside from humidity, foundation damage can also be a factor in drywall cracks. Wall cracks are often a result of foundation movement, which can put stress on the walls and result in fractures in the drywall. Therefore, it is important to address any foundation issues promptly to prevent further damage to the drywall.
