Reason and Fixing for Bulging Drywall

You need to know the causes of bulging drywall seams. That’s because you can take proper steps only after knowing the exact cause. There can be tons of reasons for bulging drywall seams. We are here with some common causes; one of them might be the reason for your bulging drywall.

Water Leakage

It is a common problem due to the poor plumbing process behind the drywall. If plumbing isn’t done properly, this causes the water pipes to leak, which gathers water behind the drywall.

Because of the leakage, you will often see water stains in the wall and bulges of drywall seams falling down significantly.

Drywall Water leakage

What to Do?

  • Find out the exact point where water leaks from the pipe.
  • If the damage to the water pipe is minor, just repair it. You can follow this guideline. Otherwise, you need to change the whole pipe in case of major leakage.
  • Let the area be open for some days to dry properly.
  • You need to work with the whole drywall setup in this case. After being dry, replace the drywall with a new one.

Loose Screws

During wall construction, all the screws should be completely driven into the wall. If not done so, those screws might get loose or sometimes can get missing inside. Often, the screws might go too deeper into the wall than general. These affect the drywall making the seams bulging.

Loose Screws

If you notice that the drywall is going inside after pushing against the bulge, you can confirm that loose screws are the cause of this bulging.

What to Do?

  • Identify the place in drywall with faulty screws.
  • Remove the parts of the drywall compound around the faulty screw.
  • If the screw is still there having the decent condition, tighten it up with a screwdriver. Replace the screw in case of a damaged condition. In case of deeper-driven screws, pluck it up.
  • If a screw is missing, get a new one to drive into the drywall.
  • Fill the area of the screw head with necessary layers of compound.
  • For fixing the uneven surface of the compound, rub it with 150-grit sandpaper.
  • Finally, paint that particular space on the drywall for a complete finish.

Too Close Drywall Panels

Due to poor construction of drywalls, construction workers might place the drywall panels too close to each other. This often creates a mess. That’s because a minimum space is necessary between two panels for solid-made drywall.

For having too close panels, the drywall can’t become enough strong and hard. So, you might experience bulging drywall seams.

Too Close Drywall

What to Do?

  • Spot the area and remove those bulges with 150-grit sandpaper.
  • If needed, use new drywall tape by removing the previous one.
  • Fix the bulging area with layers of compound.
  • Use sandpapers for smoothing the newly done area.
  • Then, the final part is painting for making a new comeback for your drywalls.

Thin Drywall in Ceiling

Thin drywalls are a result of a highly irresponsible construction process. There is a standard width that should be maintained by workers while making drywalls. In this case, bulging isn’t a small issue because this can lead to dangerous accidents like collapsing the whole wall.


As you know, thin drywalls can make you have a sagging ceiling which is very unpleasant to look at.

If you replace the whole ceiling with drywalls, you can surely fix this perfectly. But it is time-consuming and requires hard work that also needs a large amount of money. Instead, you can follow some household-friendly steps to fix this.

What to Do?

  • It is better to clear the bulging area with sandpaper. That’s because the furring stripes might not stick properly over the uneven bulges on the ceiling.
  • Install furring stripes 1×3 inches covering the drywall. For avoiding further bulging, install the strips on each ceiling properly.
  • Put layers of drywall over the furring strips to cover up the whole area. But, do not overfill the area with insulation.
  • Over the drywall, apply a joint compound coating.
  • Smoothen the surface with 150-grit sandpaper.
  • Paint the whole area to match with the other ceilings.

Final Words

If you are not a person doing such kinds of repairing work, it would be better if you ask for a professional. In case of some complex problem, it is a must to find a contractor. Because if you try to fix this even after not having any experience regarding this, it may end up having a disaster. But often, you might need an instant solution for fixing common drywall issues. For such cases, you will find the above information and guidance regarding how to fix bulging drywall seams quite helpful.
