There is no denying that for homeowners Internal Wall Cracks can be a source of stress for homeowners, causing worries about potential structural issues and costly repairs. However, not all cracks are created equal, and understanding their causes can help you address them effectively. From rushed renovations to foundational shifts, let’s explore some common reasons behind wall cracks and how to fix them.

Help! Why Do I Have a Crack in the Wall?

You rushed through renovation

One of the most common reasons for cracks in the wall is rushing through renovation work. Unfortunately, delays or disruptions are prone to happen. So, you need to account for them too. If you’ve ever hurried to complete a project, you might have skipped essential steps. For instance, painting over plaster that hasn’t fully dried can lead to cracks in the paint. While these cracks aren’t in the structure itself, they can still be unsightly and frustrating.

When plaster isn’t allowed to dry completely, it can shrink and crack under the paint. To avoid this, ensure you follow the proper drying times for materials like plaster and paint. Patience in the renovation process can prevent these superficial cracks and save you from the hassle of repainting.

You have insulation issues

Cracks in walls can also result from insulation issues, particularly water infiltration or severe leaks. When water seeps between walls and later dries out, it can leave cracks in its wake. 

To identify water infiltration issues, look for signs such as discoloration, damp spots, or mould growth on your walls. Check your home’s exterior for cracks or gaps where water might enter, and inspect your roof and gutters to ensure they’re directing water away from your house properly. Fixing leaks promptly can prevent further damage and keep your walls crack-free.

The foundations are moving

Foundation movement is another serious cause of wall cracks. If your home’s foundations are shifting or sinking, it can lead to cracks in both interior and exterior walls. Identifying foundation issues early is crucial to preventing extensive damage.

Signs of foundation movement include floors that are no longer level, doors, and windows that don’t close properly, and noticeable gaps around window frames. You can use a level to check your floors and see if they have a consistent slope. If you suspect foundation issues, it’s best to consult a professional who can provide a thorough assessment and recommend appropriate repairs.

The inner structure is damaged

Damage to your home’s inner structure, such as weakened beams or inadequate support, can also lead to cracks in walls. For example, beams in ceilings may not be sturdy enough to support the weight of the house, or a roof might not be strong enough for new installations like solar panels.

If you’re adding significant weight to your home, such as installing heavy solar panels, it’s essential to ensure your roof and underlying structure can handle the load. Consulting a structural engineer can help you determine if your home’s framework needs reinforcement to prevent cracks and other damage.

Cracks in walls can be worrying, but understanding their causes can help you address them effectively. Whether they’re the result of rushed renovations, insulation issues, foundation movement, or structural damage, identifying the root cause is the first step in making necessary repairs. By taking a careful and informed approach, you can maintain the integrity of your home and avoid the stress that comes with unexpected wall cracks.
