The Ultimate Guide to Fixing Cracks in Drywall

Drywall is one of the most common building materials used in modern construction. It is easy to install, affordable, and versatile. However, one of the most common problems that homeowners face is cracks in their drywall. Cracks in drywall can be caused by a variety of factors, including settling, humidity changes, and even normal wear and tear. Fixing Cracks in Drywall is crucial, better let the professional drywall installer handle that! 

Types of Drywall Cracks

Before we dive into how to fix drywall cracks, it is important to understand the different types of cracks that can occur. Here are the four most common types of drywall cracks:

1. Horizontal Cracks
   Horizontal cracks typically occur near the ceiling or near a door or window. They are usually caused by settling, which can cause the drywall to shift and crack horizontally.
2. Vertical Cracks
   Vertical cracks are often caused by temperature changes, humidity changes, or settling. They can appear in various areas of the wall and can be a sign of a more serious problem.
3. Hairline Cracks
   Hairline cracks are very thin and are usually caused by the natural expansion and contraction of the drywall. They are typically not a cause for concern and can be easily repaired.
4. Corner Cracks
   Corner cracks can be caused by a variety of factors, including poor installation, settling, or physical damage. They can be more difficult to repair than other types of cracks.

Causes of Drywall Cracks

Now that you understand the different types of drywall cracks, let’s take a closer look at the most common causes:

1. Settlement
   Settling is one of the most common causes of drywall cracks. As a house settles, the drywall can shift and crack, especially in areas where there is a lot of stress.
2. Humidity Changes
   Humidity changes can cause the drywall to expand and contract, which can lead to cracks over time. This is especially true in areas with high levels of humidity.
3. Temperature Changes
   Extreme temperature changes can also cause the drywall to expand and contract, which can lead to cracks. This is especially true in areas with a lot of temperature fluctuation.
4. Poor Installation
   Finally, poor installation can also cause drywall cracks. If the drywall is not installed properly, it may shift and crack over time.

Tools and Materials Needed

Before you start fixing your drywall cracks, you will need the following tools and materials:

• Joint compound
• Drywall tape
• Putty knife
• Sandpaper
• Paint

Steps to Fix Drywall Cracks

Now that you have your tools and materials, let’s get started fixing your drywall cracks. Here are the steps:

• Preparing the Area
  The first step is to prepare the area around the crack. This involves removing any loose drywall or debris around the crack and cleaning the area with a damp cloth. Then, apply a piece of drywall tape over the crack to reinforce it.
• Applying Joint Compound
  Next, apply a thin layer of joint compound over the tape, making sure to completely cover it. Smooth out any excess joint compound using a putty knife.
• Sanding and Smoothing the Joint Compound
  Once the joint compound has dried, use sandpaper to smooth out any rough spots or bumps. Be sure to wear a mask to avoid inhaling the dust.
• Adding Another Layer of Joint Compound
  Apply another thin layer of joint compound over the first layer, extending it out about six inches from the crack. Again, smooth out any excess joint compound using a putty knife.
• Sanding and Finishing the Wall
  Once the second layer of the joint compound has dried, sand the wall again to create a smooth finish. Then, you can apply paint to match the surrounding wall.

Tips for Preventing Drywall Cracks

Preventing drywall cracks is much easier than fixing them. Here are some tips to help avoid cracks in drywall in the future:

1. Proper Installation
   Make sure that your drywall is installed properly. Hire a professional drywall installer if necessary to ensure that your drywall is installed correctly and securely.
