10 Steps on How to Fix a Bowed Interior Wall

Step 1: Diagnosing the Cause of a Bowed Wall

Before you begin any repairs, it’s essential to determine what caused your interior wall to bow in the first place. This could be due to several factors, such as foundation settling, moisture damage, or inadequate support for heavy loads above. Identifying the root cause will help you address the issue adequately and prevent future recurrence.

Step 2: Remove Drywall

If your wall has bowed significantly, you may need to remove sections of drywall to access the underlying structure. Use a level and measuring tape to mark the area that needs to be removed, then carefully cut along the lines with a utility knife. Wear protective gear and have a drop cloth or tarp to catch any debris.

Step 3: Install Jack Posts

Need to Install Jack Posts

If your bowed wall is due to foundation settling or an uneven load above, you may need to install jack posts for support. These adjustable steel posts can help lift and stabilize the wall back into place. Follow the manufacturer’s instructions for proper placement and installation.

Step 4: Brace the Wall

For heavily bowed walls, you may also need to add support by bracing the wall with plywood or a similar sturdy material. This will help distribute the weight and prevent further bowing. Use a level to ensure the brace is straight, and secure it with nails.

Step 5: Check for Plumbing or Electrical Issues

If your wall is bowed due to moisture or other issues, it’s essential to check for any underlying plumbing or electrical problems that may have contributed. Consult a professional to address these issues before continuing with the repairs.

Step 6: Fix Moisture Issues

If moisture is the cause of your bowed wall, be sure to fix any leaks or sources of excess moisture before proceeding with repairs. This will prevent future damage and ensure the stability of your wall.

Step 7: Straighten the Wall

Slowly and carefully push or pull the wall back into place using a level. This may require some trial and error to get it perfectly straight. If using jack posts, adjust them accordingly as you straighten the wall.

Step 8: Secure the Wall

Once the wall is straightened, secure it in place with screws or nails. Be sure to use enough fasteners for proper support.

Step 9: Replace Drywall

If you had to remove sections of drywall, now is the time to replace them. Cut new pieces to fit and secure them in place with drywall screws or nails.

Step 10: Finish and Paint

Finally, finish your repair by filling gaps or holes with a spackling compound and sanding it smooth. Then, paint the wall to match the rest of your interior. Congratulations – you have now successfully fixed a bowed interior wall!

Fixing a bowed interior wall may seem daunting, but it can be easily accomplished with the right tools and knowledge. Remember to diagnose the cause of the bowing properly, use appropriate support and bracing if needed, and address any underlying issues before repairing the wall itself. With these steps and a little patience, your fence will return to its straight and sturdy state in no time. 

5 Things to Avoid When Fixing a Bowed Interior Wall

While the steps outlined above will guide you through the process of fixing a bowed interior wall, there are also some common mistakes to avoid:

1. Ignoring the Underlying Cause

As mentioned earlier, it’s crucial to identify and address the root cause of your bowed wall. Simply fixing the visible damage without addressing the underlying issue will likely lead to recurring problems.

2. Rushing or Skipping Steps

Repairing a bowed interior wall takes time and attention to detail. Rushing through or skipping steps can result in an unstable or poorly repaired wall. Take the time to properly diagnose, support, and secure your border for the best results.

3. Using Inadequate Bracing

Bracing Materials for Heavily Bowed Walls

It’s essential to use strong and sturdy bracing materials for heavily bowed walls. Cutting corners or using flimsy materials can lead to further damage or an ineffective repair.

4. Neglecting Safety Measures

When removing drywall or working with heavy materials and tools, it’s essential to follow safety precautions such as wearing protective gear and having a helper. Neglecting these measures can result in injuries or accidents.

5. Improper Finishing Techniques

While filling holes and painting may seem simple, using the proper techniques and materials for a seamless finish is essential. Taking shortcuts or using low-quality products can result in an unappealing appearance that may need redone.  Patience, attention to detail, and addressing all necessary steps and precautions will ensure a successful repair of your bowed interior wall. 

5 Additional Tips for Maintaining Straight Interior Walls

Now that your bowed interior wall is fixed, preventing the issue from happening again is essential. Here are some helpful tips for maintaining straight and sturdy walls in your home:

2. Address Moisture Issues Promptly

Any signs of water damage or excess moisture should be addressed immediately to prevent further damage to your walls. This includes fixing leaks, properly ventilating humid areas, and waterproofing basements or crawl spaces.

3. Avoid Heavy Loads Above Walls

Avoid placing heavy furniture or equipment on walls that may not be able to support the weight. This can cause bowing and other structural issues over time.
