How to Spot Cracks in Walls and Fix Them Like a Pro

One of the most common issues that homeowners encounter is seeing cracks in their walls. While these lines are often not serious, they could affect the overall aesthetic of your home. Fixing these imperfections can also help address underlying issues. Therefore, it’s important to know what to do when you see cracks in your home with these simple yet proven tips from the experts.

Determining the Cause of Cracks in Walls

Before fixing the crack, identify the cause first, and then what type of crack it is. After identifying it, prepare the tools and materials to start repairing the cracks. Remember that there are different methods to repair hairline cracks in plaster walls and drywall. Assessing the situation is essential in determining what technique to use and how to properly address any structural issues.

For instance, it may require patching, sealing, or re-plastering to fix cracks and ensure smooth and successful wall repair. To identify the cause, there are different factors that could trigger wall cracks. A common cause is the foundation itself due to structural problems. Check for any signs of compromised foundation, such as misaligned doors and uneven floors.
​
Another potential issue that can cause cracks is water damage. It could be due to poor drainage, high humidity, or leaking pipes. Make sure to inspect your kitchen and bathroom with plumbing fixtures, where water damage could be leading to damaged walls. Other areas in the house that may also show signs of water damage include basements and garages.

Identifying the Type of Wall Crack

If you see wall cracks around your home, it’s important to assess the type of cracks so you’ll know how to approach them. The most common types of cracks in walls are vertical cracks, diagonal cracks, and hairline cracks. Each type has unique characteristics, so different methods should be used to fix underlying issues.
​

• Vertical cracks – These lines are running straight up and down and can be a sign of foundation problems. If it’s just a small crack and doesn’t widen over time, you can simply use a patching compound to fix it. Now, check if it’s wider than 1/8 inch because it might be serious and need a structural engineer to assess the situation.
      
• Diagonal cracks – These cracks occur at an angle and may signal an underlying structural issue or differential settling. If there’s lengthening or widening of these cracks over time, consult an expert to prevent further damage.
      
• Hairline cracks – These are very thin and barely visible cracks that appear because of slight movement or normal settling. Hairline cracks are nothing serious and can be fixed by light patching or painting.
