How to Fix Bulging Drywall

Drywall can absorb a lot of moisture, which can result in swelling and bulging. In today’s post, Handyman Connection® of Orange County discusses the causes of bulging drywall and how to fix it.

Overdriven Fasteners

Drywall requires precise installation techniques. Not securing the drywall board to the studs while fastening, or overdriving the fasteners into the boards can damage the drywall paper or the outer layer that holds the drywall material together. This will let the moisture from the drywall compound to infiltrate the drywall itself, which will result in a bulge. To fix this problem, you must remove the paper core by drilling into the damaged area. Patch the area with joint compound, then let it dry before sanding and repainting.

Plumbing Leaks

Water from leaky pipes can make its way into the drywall and cause bulges. These bulges may also be present in ceilings that have come into contact with leaking water. In addition to bulging, you may also notice water stains like the ones that appear when you have a leaking roof.

Bulging caused by leaky plumbing generally takes more repair work than that caused by overdriven fasteners because the plumbing leak will need to be addressed. The extent of moisture damage may be more widespread; therefore, an entire drywall panel or several panels will need to be replaced. If the damage is concentrated in a small area, you may be able to cut out part of the board and replace it with a piece of the same size.

Insufficient Fastening

Bulges that appear where two drywall boards meet are usually caused by the boards pulling away from the studs. This usually happens when not enough fasteners and/or when the wrong type of fasteners are used. Fasteners should be applied at least every 12 inches to properly secure each panel. Loose drywall boards can be refastened using additional screws, however, if the boards are bent or damaged, you need to replace them with new ones.
