HomeCommon Causes of Exterior Wall Cracks, Their Types, and How to Fix Them
Feb 27, 2024
If you notice a crack on your wall, you may wonder if it is just an eyesore or a sign of something serious. Exterior wall cracks can indicate deeper issues like moisture intrusion, poor construction, or even foundation settling. Left unchecked, these cracks can compromise your home’s structure and value. Understanding the root causes and addressing
them promptly is essential for every homeowner.
Let us break down the common reasons for wall cracks, their types, and the best ways to fix wall cracks effectively.
What are the Causes of Wall Cracks?
- Settling Foundation: A settling or shifting foundation is one of the leading causes of wall cracks. As your home adjusts to soil movement, minor to major cracks may appear on the exterior walls.
- Weather Extremes: Temperature fluctuations can cause building materials to expand and contract, which leads to cracks. Over time, exposure to rain, wind, and sun weakens the wall surface, especially if waterproofing wall exteriors is not properly done.
- Poor Construction Practices: Substandard materials or improper curing of concrete can result in premature cracking. Even hairline cracks can worsen without the right intervention.
- Moisture Intrusion: Water seepage from faulty drainage systems or lack of proper waterproofing contributes significantly to exterior wall cracks. Moisture can erode walls, which makes it essential to fix wall cracks as soon as they are noticed.
Different Types of Wall Cracks
Wall cracks can indicate various underlying issues, and understanding their types helps determine the urgency of repair.
- Horizontal Cracks: These are often caused by pressure on the foundation, such as soil expansion or water damage. They are a serious concern and require immediate attention to prevent structural failure.
- Vertical Cracks: Typically less alarming, these can result from minor settling of the structure. However, if ignored, they may widen over time, leading to potential water seepage.
- Diagonal Cracks: Commonly caused by uneven foundation settling or structural shifts, these signal stress on the building and warrant professional evaluation.
- Hairline Cracks: While seemingly harmless, these fine cracks can expand with time, especially in areas exposed to moisture, which makes regular maintenance essential.
How to Fix Wall Cracks?
- Inspect the Damage
For wall crack repair, Begin by assessing the depth and spread of the cracks. Surface cracks can often be repaired with simple fillers, but structural cracks may need expert intervention. - Waterproofing the Exterior Walls

For small cracks, a flexible crack filler paste such as an epoxy-based solution or crack filler powder works wonders. For larger ones, structural repairs may involve injecting grout or reinforcing the wall. - Professional Help
