How to Repair Wall Cracks: Maintenance Tips & Proactive Solutions

Wall cracks are one of the most common issues faced by homeowners, builders, and property managers alike. Whether it’s a new house or an older construction, visible cracks on walls can be unsettling. Not only do they affect the aesthetics of your space, but they may also indicate deeper structural problems. Understanding the reasons for cracks in walls, learning how to fix them, and knowing how to avoid them in the future is key to effective building maintenance.

In this blog, we’ll explore the different types of wall cracks, their causes, how to repair them, and proactive measures to prevent them.

Common Causes of Wall Cracks

Before diving into repair techniques, it’s essential to understand the causes of wall cracks. Identifying the root cause ensures long-lasting repairs. 

1. Structural Movement

One of the most serious causes of wall cracks is structural movement. Foundations may shift due to soil erosion, water damage, or natural settling of the building over time. These building cracks are often wider and more dangerous, requiring immediate attention.

2. Moisture and Weather Impact

Water infiltration, excessive humidity, and seasonal temperature changes can expand or contract building materials, leading to cracks. This is especially common in monsoon-prone regions like India. Cracks caused by moisture often appear near windows, ceilings, or external walls.

3. Poor Construction Practices

Using substandard materials, inadequate curing time, or improper joint placement during construction can result in early cracks on walls in new houses. Improper alignment and lack of reinforcement are also contributors. 

Types of Wall Crack and its Meanings

Familiarizing oneself with the characteristics and appearances of wall cracks constitutes a quite vital first step in the process of distinguishing a small defect from a major structural problem. Not all the cracks are harmful, some of them cannot be seen while others may be the cause of a potentially terrifying disaster.

These are the types of wall cracks, which are considered the most common, and their explanation:

Hairline Cracks

Firstly, what are hairline cracks? These are the cracks which are very thin and usually do not exceed 1 millimeter in width. The hairline cracks are the most frequent, especially in the gypsum board, and they occur when the house is newly built and is still settling.

• They are most probably caused by: the shrinkage, a non-essential partial settlement, or just a little temperature change, especially in the case of concrete floor slabs.

• Are they hard to deal with by anyone? Usually only the surface of the wall is affected, so they are more likely to be a cosmetic problem.

• The quickest solution could be: to use putty or crack filler for a fast and easy repair job.

Vertical Cracks

Vertical cracks are the ones that expand the entire wall from the top to the bottom and are found on both the drywall and concrete surfaces.

• They are produced due to: the constant drying or and a very low-key continuous deepness settlement of the bearing structure.

• In most instances: The cracks are of medium intensity, and they need to be monitored regularly to prevent them from turning into a risk.

• Their problem generally gets solved by: using flexible sealants which can go along with the structure for a little movement.

Horizontal Cracks

Horizontal cracks are more common in basement or retaining walls and are more likely to indicate extreme damage caused by prolonged and excessive pressure from outside soil and water.

• The roots of the problem: Soil's lateral pressure, water that infiltrates, movement in the structure's system

• The distress level: Structural stability is at risk as it is of high concern and immediate need for fixing

• The prime action is to: inject epoxy glue to close the crack and support the wall by a vertical tieback

Solution: We would strongly suggest you request a prompt visit by a structural engineer since it may be necessary to carry out reinforcement.

Diagonal Cracks

Diagonal cracks, which usually occur on an incline, most often are the result of the improper installation of windows, doors, or the corner walls of the building.

• Cause: The main reasons for the appearance of such cracks are the uneven soil under the foundation or the uncontrolled rise in temperature.

• Concern Level: The size and the extent of the cracks will define as moderate to high the level of danger.

• Solution: May require some professional help to repair and accordingly, a possible correction of the foundation.
