Drywall is a common material residential contractors use to build the walls, ceilings, and partitions in most modern homes. Although relatively durable, it can sometimes develop cracks, which can be unsightly and pose a safety risk. Here are the top reasons the drywall in your home is cracking and what you can do about it.


Moisture is one of the most common reasons for drywall cracks. It can cause the drywall to expand and contract, leading to cracks. Moisture can occur in drywall in different ways, such as leaks from the roof or overflowing pipes. Addressing the source of the moisture before repairing the drywall—and before you start to see warning signs for mold—is crucial for preventing the problem from reoccurring.

Structural Issues

Structural problems in the home, such as an inadequate foundation or shifting walls, are other prominent reasons for drywall cracks. Depending on the foundation or geographical location, some houses may be more vulnerable to structural problems. Call a professional if you suspect that structural problems are causing your drywall issues.


The age of the drywall can sometimes be a factor for cracking. Old drywall is more prone to cracking, especially if it has been through multiple expansions and contractions over the years. Sometimes, the only solution is replacing the drywall with new material.

Improper Installation

Poor installation can often lead to problems with drywall. The drywall is more likely to crack and shift if the screws or nails used to attach the drywall to the studs are too far apart. Similarly, they may not sit flush with each other if the panels are not cut correctly.

Temperature and Humidity 

Extreme temperature and humidity changes can cause the drywall to expand and contract and may eventually lead to cracks. Temperature fluctuations can be the result of poor ventilation in the home or changes in the weather outside. Maintaining a consistent temperature and humidity level in your home will help reduce the chances of drywall problems.

The drywall in your home is cracking for many reasons, from moisture and temperature changes to improper installation and structural problems. It’s best to call a professional contractor to assess the situation if you notice cracks or other signs of wear in your drywall. Knowing why drywall affects the value of your property and taking the necessary steps to prevent and address any issues will help keep your home in top condition for years to come. Remember these reasons, and you can ensure your drywall will remain strong and durable.
