Neglecting water-damaged drywall can exacerbate the existing problems. Fortunately, the process of repairing water-damaged drywall is relatively straightforward. Here’s a step-by-step guide on how to restore water-damaged drywall and mitigate further damage:

Next, it’s time to cut the damaged portions of the drywall.

How to Cut Drywall 

  1. Mark a straight line along the wall — above the point where the water stopped wicking — using a chalk line.
  2. Cut along the chalk line one-half or three-quarters of the way through the thickness of the drywall. Use a utility knife.
  3. Loosen and remove the damaged portion carefully. To make that easier, knock a small hole in the damaged drywall using a hammer. Use the hole as a handle to gently pull back the drywall.
  4. Once you cut out and remove the drywall, take out all the insulation (fiberglass, mineral wool, cellulose, wood fiberboard, etc.). Even if it doesn’t seem wet, it likely is. If it’s foam plastic insulation, you can leave it in place and allow it to dry.

Once the damaged drywall is removed, start drying the area around and inside the wall. Use high-efficiency blowers and dehumidifiers and open the windows and doors. Use fans to increase airflow behind walls and leave them running for at least two days so the studs and flooring can completely dry. Avoid punching holes in walls. This practice doesn’t help the wall dry faster. Plus, it makes it harder to repair your drywall.

Use a chemical sanitizer to prevent mold and bacteria from forming between walls. Avoid bleach, as it doesn’t prevent mold from growing. To remove severe odors, use an ozone machine and leave it running for at least eight hours. Vacate the area while the ozone machine is running.

How to Replace Water-Damaged Drywall 

Now it’s time to hang new drywall. First, measure the size of the hole to help you know how much to cut out from a new sheet of drywall. Put four drywall clips around the hole and secure each one with a drywall screw.

Then, insert the drywall pieces and secure them to drywall clips. Don’t over-tighten the drywall screws. Use drywall tape and joint compound to blend it in with the existing drywall. Finally, sand the area several times for a smooth wall surface.

Painting the restored drywall is the final step. First, make sure that the joint compound is completely dry, as it would contain a lot of moisture. Then, paint the wall with a primer to help seal the area. After that, paint the entire wall to ensure the color is uniform throughout.
