Keeping Your Home in Good Shape
Plaster cracking on walls is something many homeowners notice over time. While some cracks are minor and nothing to worry about, others can point to deeper issues such as structural movement or structural damage. Understanding the types of cracks, their causes, and how to fix them is essential to keeping your home in good shape.
At DAMAX Design Solutions, we help homeowners assess and repair cracks in plaster walls, ensuring both safety and long-term durability. Whether you’re dealing with a small crack or more serious structural issues, here’s what you need to know.
Why Does Plaster Crack?
Plaster can crack for several reasons. Some cracks are caused by natural settling of the property, changes in temperature or humidity, or poor initial plaster application. In other cases, cracks are signs of structural integrity concerns, such as foundation issues or structural movement within the property.
Cracks can appear in walls or ceilings, especially around door frames and windows where pressure tends to build up. If you notice diagonal cracks, long horizontal lines, or wide gaps forming, it’s important to investigate further to rule out structural damage.
Types of Cracks in Plaster Walls
Not all wall cracks are equal. Here are some of the most common types of cracks found in plaster walls:
• Hairline cracks: Thin and surface-level, usually due to drying shrinkage or temperature changes.
• Vertical cracks: Often found near door frames or windows and may indicate structural stress.
• Diagonal cracks: Typically more concerning, especially if they extend from corners, as they may relate to foundation movement.
• Cracks in plaster near the ceiling: These may suggest roof load issues or loose plaster pulling away.
• Loose plaster and flaking: May occur with older homes or where moisture is present.
If you’re unsure which type you’re dealing with, it’s best to consult a professional like Damax Design Solutions to evaluate whether it’s cosmetic or structural.
When to Worry About Cracks
Some wall cracks are nothing more than superficial marks from drying plaster or seasonal changes. Others can signal bigger problems. Here are signs that you should take seriously:
• Cracks wider than 5mm
• Cracks that keep growing
• Multiple diagonal cracks spreading from the same area
• Cracks accompanied by doors sticking or sloping floors
• Gaps appearing near door frames
These could be indicators of structural damage or deeper structural issues that may require the help of a structural engineer.
How to Repair Cracks in Plaster Walls
Fixing cracks in plaster depends on the size, cause, and severity. For basic cosmetic fixes, you can handle them with a few DIY tools. Here’s how to repair simple hairline cracks:
1. Score the Crack
Use a Stanley knife to carefully open the crack slightly. This helps the filler bond more effectively.
2. Clean the Area
Remove any dust or loose plaster around the crack to ensure a clean surface.
3. Apply Compound Over the Crack
Use a filler or plaster repair compound and smooth it over the crack using a putty knife.
4. Sand the Area
Once the compound is dry, sand the area to blend it in with the wall.
5. Repaint
Finish by repainting the repaired area for a seamless finish.
For cracks larger than 5mm, especially cracks in your walls that keep coming back, you may need reinforcement or even structural repair. If you notice repeated cracking, it’s best not to ignore it.
The Importance of Consulting a Professional
While minor cracks can often be fixed yourself, deeper or repeated cracks might be tied to structural movement or foundation shifts. In these cases, a structural engineer should inspect the issue to ensure it isn’t part of a larger problem.
At DAMAX Design Solutions, we don’t just repair cracks—we identify the root cause, whether that’s poor construction, ground movement, or wear and tear. Our experts can provide a clear diagnosis and long-term solutions.
Preventing Future Cracks
To minimise future wall crack issues:
• Ensure proper ventilation to prevent moisture buildup
• Monitor areas near door frames and ceilings
• Avoid heavy loads on weak sections of plaster walls
• Conduct regular visual checks for changes
When working on renovation projects, our team also helps reduce risks by applying high-quality materials and reinforcing vulnerable areas from the start.
