- Natural House Settling
The natural process of homes settling is due to the soil under the foundation of the structure shifting. The slight movement process may result in the light stress of the drywall surfaces, causing small cracks along the window, door, or ceiling joints. These cracks tend to be thin and, in most cases, cosmetic.
- Temperature and Humidity Changes
Humidity and temperature changes cause the materials of the drywall to expand and contract. In the long run, this repetitive action makes the joints and seams weak and leaves cracks visible. This kind of drywall damage usually happens in homes located in areas where there are seasonal climatic changes.
- Poor Drywall Installation
Other significant reasons for drywall cracks are improper installation. The joints can get weak if the drywall sheets were not taped, screwed, or finished properly during the construction. With normal movement of the building, the poorly secured seams may start splitting or cracking.
- Structural Movement or Foundation Problems
The cracks could be an outcome of a structural movement in the building, or larger and expanding. Issues with the foundation, moving soil, or unequal settlement may put a strain on the walls. These cracks can be either wider or diagonal, or even cover several parts of the wall.
- Water Damage and Moisture
Moisture is usually a leading cause of the deterioration of drywall. Plumbing, roofs, and high humidity do not provide any advantages to the material of drywalls, which can be weakened and swell up. The material will dry up and consequently, may not dry evenly, with cracks and broken surfaces being left behind, which need repair.

- Inspect and Prepare the Area
Any crack should be carefully inspected in order to find the cause and the size of the crack before initiating repairs. Clear any loose paint or debris that surrounds the area that is damaged and make the surface clean. It is important to make sure that the repair materials stick to the wall with the assistance of proper preparation.
- Widen the Crack Slightly
With a utility knife, carefully enlarge the crack in order to make a small groove. This process enables the joint compound to fill the gap in a better manner. It also eliminates weak edges of dry to walls that may lead to failure of the repair in the future.
- Tape Tile with Drywall Tape
So as to strengthen the crack, put the drywall mesh tape or paper tape over the crack. This tape helps to reinforce the repaired part and avoid the recurrence of the crack. Make sure that the tape is against the wall in a flat position with no bubbles and folds.
- Spread Joint Compound Evenly
Apply joint compound in a thin layer using a putty knife on the taped crack. Rub the compound out in order to blend it into the wall surface it is on. Let the compound dry out, then move to the next step.
- Sand, Prime, and Repaint
When the compound is dry, sand lightly the part that is repaired until it is smooth and even with the wall. Use a primer to close the repair and paint the wall again to have the appearance and finish it had before.
