Solutions to Typical Drywall Issues: A Troubleshooting Guide

Drywall is a widely used building material known for its versatility, but it can be prone to various issues during and after installation. From cracks and nail pops to uneven seams and texture problems, these typical drywall issues can detract from the appearance of your walls and ceilings. In this article, we will explore common drywall problems and provide practical solutions to help you troubleshoot and resolve them effectively.

Solutions to Typical Drywall Issues:

1. Problem: Nail Pops

  • Cause: Nail pops occur when drywall nails or screws become loose and push through the surface, creating small bulges or craters.
  • Solution: To fix nail pops, follow these steps:
    • Gently tap the nail or screw back into place, so it sits below the surface.
    • Apply joint compound over the area and feather the edges.
    • Sand the surface smooth and repaint or retexture as needed.

2. Problem: Cracks in Drywall Seams

  • Cause: Cracks in drywall seams can result from settling, temperature fluctuations, or improper installation.
  • Solution: Repair cracked drywall seams as follows:
    • Use a utility knife to remove loose or damaged tape and joint compound.
    • Apply a fresh layer of joint compound and embed a new piece of drywall tape.
    • Feather the edges, sand, and repaint or retexture.

3. Problem: Uneven or Bumpy Texture

  • Cause: Uneven or bumpy texture often occurs due to inconsistencies in applying joint compound or texture material.
  • Solution: Achieve a smoother texture with these steps:
    • Sand the uneven texture lightly, focusing on the high spots.
    • Apply a thin layer of joint compound to level the surface, feathering the edges.
    • Sand the surface until it is smooth, and then repaint or retexture.

4. Problem: Visible Drywall Seams

  • Cause: Visible seams can result from improper taping and finishing techniques.
  • Solution: Hide visible seams as follows:
    • Scrape away any loose or damaged joint compound.
    • Apply a thin layer of joint compound over the seam, feathering the edges.
    • Sand and repaint or retexture for a seamless finish.

5. Problem: Water Damage Stains

  • Cause: Water damage stains are caused by leaks or excessive moisture, leading to discoloration and deterioration of the drywall.
  • Solution: Repair water damage stains as follows:
    • Ensure the source of moisture is fixed before addressing the drywall.
    • Cut out and replace the damaged drywall section.
    • Apply a stain-blocking primer to prevent the stain from bleeding through, then repaint.

6. Problem: Sagging Drywall Ceilings

  • Cause: Sagging drywall ceilings can result from inadequate fastening or the use of low-quality drywall.
  • Solution: Correct sagging ceilings with these steps:
    • Locate the ceiling joists and reinforce them as needed.
    • Lift and secure the sagging drywall to the joists with screws.
    • Apply joint compound and finish the surface as usual.

7. Problem: Bubbling or Loose Wallpaper

  • Cause: Bubbling or loose wallpaper can occur due to improper adhesive application or drywall surface issues.
  • Solution: Address bubbling wallpaper with these steps:
    • Carefully peel back the loose sections of wallpaper.
    • Apply wallpaper adhesive to the drywall surface and press the wallpaper back in place.
    • Smooth out any bubbles or wrinkles, and ensure a secure bond.

8. Problem: Mold or Mildew Growth

  • Cause: Mold or mildew growth on drywall is typically due to excessive moisture in the environment.
  • Solution: Eliminate mold or mildew on drywall as follows:
    • Identify and fix the source of moisture.
    • Clean the affected area with a mixture of water and mild detergent.
    • Allow the area to dry thoroughly, and consider using a mold-resistant primer and paint.


Common drywall issues can arise during and after installation, but with the right solutions, they can be effectively resolved. Whether you’re dealing with nail pops, cracks, uneven textures, or other problems, addressing them promptly and following the recommended repair steps will help you maintain the appearance and structural integrity of your walls and ceilings.
