What Are the Most Common Causes of Cracks in Drywall

Drywall is a type of wall material that is commonly used in construction. It is made from panels of gypsum plaster that are sandwiched between two layers of heavy paper. Drywall is a very popular choice for walls because it is relatively inexpensive and easy to install.

However, drywall is not without its issues. One common problem that homeowners face is cracks in their drywall. Cracks can occur for a variety of reasons, but some are more common than others.

Thermal Expansion and Contraction

As the weather gets colder, you may notice cracks in your drywall. These cracks are usually caused by two things: thermal expansion and contraction.

Thermal expansion is when materials expand when heated and contract when cooled. This can cause cracks in drywall because as the temperature outside changes, the drywall expands and contracts. The expansion and contraction are more pronounced in areas with a big temperature difference, such as near windows or doors.

To help prevent thermal expansion from causing cracks in your drywall, make sure to seal any gaps around doors and windows. You can also add insulation to reduce the amount of temperature change in your home.

Contraction is the opposite of expansion and happens when materials cool down. This can also cause cracks in drywall, as the drywall contracts and pulls away from the framing.

To help prevent contraction from causing cracks, make sure your drywall is properly secured to the framing. You can also add insulation to help keep the temperature inside your home consistent.

House Settling

There are many reasons why cracks might start to appear in your drywall. But one of the most common reasons is simply because your house is settling. Over time, as your house settles into the ground, it can cause cracks in the drywall.

This is especially true if your house is built on a foundation that is not level. As the foundation settles, it can cause the walls to start to lean, which can then lead to cracks.

There are other causes of cracks in drywall, but if you notice them appearing, it's a good idea to have a professional inspect your home to see if settlement is the cause.

Water Damage

Several types of cracks can occur in drywall, but the most common is caused by water damage. Water damage can occur from a number of sources, including leaks, floods, and condensation.

Leaks are perhaps the most common cause of water damage to drywall. Leaks can occur in both the home and commercial buildings. They can be caused by many things, including faulty plumbing, damaged roofs, and even window leaks.

Floods are another common source of water damage to drywall. Floodwaters can enter a home or building through a number of ways, including doors, windows, and even cracks in the foundation. Once the water enters the building, it can quickly saturate the drywall, causing it to swell and eventually crack.

Condensation is another cause of water damage to drywall. Condensation can occur when there is high humidity in the air. This can happen when there is a lot of cooking or showering going on in the home or even when the weather is very humid. When the air becomes saturated with water, it can cause the drywall to absorb moisture, eventually leading to cracking.

Final Thoughts

Drywall cracks are a common occurrence in many homes. While they may not be severe, they can be unsightly and cause problems if left unrepaired. No matter the cause of the cracks, it's essential to address the issue as soon as possible.
