One of the biggest misconceptions about exterior walls is that every crack has the same cause.
In reality, cracks can develop for many different reasons and understanding the cause is the first step towards choosing the right solution.
Here are some of the most common types you may notice:
🪨 Hairline cracks
Fine, surface-level cracks that often appear as part of normal ageing or minor movement. While they may seem harmless, they're still worth monitoring, as they can allow moisture to pe*****te over time.
🏠 Settlement cracks
As buildings naturally settle, small cracks can develop. These often appear in predictable locations and should be assessed to determine whether they're simply cosmetic or require repair.
🌡️ Movement cracks
Walls expand and contract as temperatures change. Over time, this movement can place stress on the exterior surface, causing cracks to develop around joints, corners, or openings.
💧 Moisture-related cracks
Water can weaken exterior surfaces over time, leading to deterioration and cracking if the underlying issue isn't addressed.
The important thing to remember is this: a crack isn't a diagnosis. It's a symptom.
That's why simply painting over a crack isn't always the answer. Before any repair or coating is applied, it's important to understand what caused the crack in the first place.
