How to Clean Mold From Your Walls and Flooring

After a flood or an incident where water damage has occurred inside your home, you may experience mold growth on several types of surfaces inside the home. Mold and its airborne spores can cause health problems in you and your family, so it is important to clean up and remove the mold as soon as possible and as efficiently as possible. Here are some tips to help you remove and clean up mold from your home's interior walls and flooring.


When drywall has become wet, it can become saturated and hold in the moisture to allow mold growth to occur. If the home flooding has allowed water to get inside your walls, you should cut out the damaged sections of drywall with a utility knife, as mold growth can occur behind the wall and you may not be aware of it. This can result in mold spores remaining inside your home.

Remove the moisture damaged drywall and any wet roll-batting insulation. Check the wall studs to make sure there is no mold growth upon them. Wipe off any mold growth from the wood studs using a rag and a mixture of bleach and water. Allow the studs to air dry. Replace the drywall with new sections and install new insulation inside the wall to restore the wall to its former condition. 

If the mold growth is only forming on the exterior of your walls due to high moisture levels in the air, you can wipe the walls clean with a bleach and water mixture and a cleaning rag. Discard the rag after you are finished cleaning up the mold to prevent any mold spores from remaining inside your home.


When your floors have become moldy due to high moisture levels or standing water upon their surface, you will need to remove the mold or replace the flooring. It is recommended to replace any carpeting and padding that has become moldy, as it is difficult to fully remove all the mold from this type of flooring. However, you can attempt to remedy the mold with a bleach and water mixture with your carpet cleaner.

To complete this, combine one cup of bleach in your carpet cleaning basin. Spray to apply the solution onto the moldy carpet and allow it to sit for 15 to 20 minutes. Use the carpet cleaner to suck up all the bleach and water solution along with the mold. Make sure you dry the carpeting as soon as possible. Open windows in your home, direct fans onto the carpeting, and even turn on your home's heating system to dry the carpeting as soon as possible to prevent mold regrowth.
