Causes of Interior Wall Cracks

Some of the most common causes for cracks on an interior wall include;

Too Much Moisture

Too much moisture in the masonry of a property can lead to the structural materials to swell, rot and weaken. Water is one of the most common causes of structural issues within a building. This can make the walls crack, crumble and even begin to develop mould. If you think that your wall cracks may be caused by moisture in the masonry, then you should really consider calling a wall crack repair expert to evaluate the cause and extent of the situation.

Weather Changes

Drastic weather changes can cause small cracks to appear, this is due to the structural materials that make up your home to expand when it’s warmer and shrink when it’s colder. This expansion and shrinkage of the brickwork can commonly cause cracks, although this is generally nothing to worry about.


Settling occurs if the home has property sits on top of unstable soil. After time, this can cause your home to sink or settle into the ground. This can cause cracks in the walls (especially near the ceiling and above the doorframes) as it is generally one section of the building that will sink first. This is a serious issue that you should address sooner rather than later, structural repair, as well as wall crack repair, will be essential for this.

Heavy Objects

Sometimes something as simple as hanging something on the wall which is too heavy can cause cracks in the internal walls. These objects (such as picture frames) usually cover the cracks so many people don’t notice until the paintings get removed.

Poor Dry Wall Installation

If walls aren’t insulated properly cracks in the drywall will more than likely appear. The seams between the drywall sheets must be properly taped smoothed and sealed to ensure that this doesn’t happen.
