Eliminate Mold From Drywall

Step1

Determine if you have mold. Typically, you can smell when mold is present in a home. A mildew smell probably means there is mold located somewhere inside.

Step2

Find the mold. Mold is typically located in areas were there is water damage. This is frequently in the basement, attic, near windows and doors, in rooms with lots of plumbing (like the bathroom) and behind appliances that use water. These appliances include refrigerators, dishwashers and water heaters.

Step3

Put on protective gear, including protective gloves, goggles and a breath mask/respirator. When you remove mold, you become extra vulnerable to its health risks.

Step4

Determine the extent of the mold. This is done visually. You have to get into the wall or ceiling and see how far the mold extends in the area.

Step5

Cut out any drywall affected by mold using a utility knife. Moldy drywall cannot be cleaned. Instead, it must be completely removed and disposed of.

Step6

Sand the surface of any wood studs attached to moldy drywall to completely remove visible mold. Scrubbing wood may not be enough to guarantee mold removal.

Step7

Clean surrounding surfaces using a disinfecting solution of bleach and water. Allow bleach to penetrate the area for at least 15 minutes to achieve complete disinfection.

Step8

Rinse the affected area thoroughly with clean water to remove the bleach.

Step9

Allow the moldy area to dry completely before installing new drywall. Use fans and/or dehumidifiers to speed up the drying process.

Tips & Warnings

Assume the presence of mold in any drywall that is wet for more than 24 hours.
Use plastic sheeting to isolate areas where mold is being removed if the home remains occupied during removal. Removing mold can release more spores into the air, which can be harmful if inhaled.
Hire a trained professional to clean up extensive mold damage. Mold should be taken seriously.
