How to fix drywall cracks? - Are drywall cracks being severe?

Trust me! No one wants to take a risk when it comes to drywall cracks! Drywall cracks can seem to have less risk potential, but if handled carelessly, it was the primary reason for your home’s structural damages. But, if you see a crack in the wall, it doesn’t necessarily mean there’s an issue with the home’s foundation. It can likely be patched and repaired. But drywall cracks are the first sign that your home is not maintained well because other than damage, it also affects your home’s interior look and makes it less attractive, and no one wants that too! 

"I'm noticing a lot of tiny cracks in my drywalls; do I have a structural problem?"

It’s improbable that those small hairline cracks that you see on the drywall in your home, over the doors and windows are actual structural problems. It’s usually just a slight thermal expansion that can be repaired very easily by just using a little lightweight spackling.

But the type of crack you need to be concerned with is 3/16 of an inch or more. If one side of the crack is not equalized with the other side of the damage, that can indicate some active structural movement. 

Another telltale sign is if the doors in your home don’t fit the fixes quite as well as they used to. Again, you need to call an expert to examine the severity and fix them for you in this situation.

How do you find the severity of your drywall cracks?

Critical – cracks up to 25mm wide could be a symptom of structural damage and should be examined and fixed by a professional. 

Hypercritical – any crack above 25mm in width indicates severe structural damage and will need significant repair work, which could include foundation and rebuilding.

  6. Cut a piece of scrap like a 2 to 4 inches bigger than the hole to serve dispatch support and carefully secure to the wall with drywall screws.
