Basements are prone to excessive moisture and water damage.

A flood caused by periods of heavy rain or a busted pipe can wreck havoc on your basement floors. Even after you have successfully cleaned the basement floors, you must take the necessary precautions to prevent future mold growth. Basements -- especially those dealing with water damage -- provide an ideal breeding environment for fungus such as mold and mildew. Once the mold begins to grow in your basement, it can quickly take over and spread to other areas of your home.

Step 1

Remove any water sitting on the basement floors. Use a sump pump attached to a water hose running outside -- and away from your home -- to pump out the excess water. When using a sump pump, make sure it is submerged in the water and sitting on a flat surface. Pump out 3 feet or less of water a day. Pumping out more than 3 feet a day may cause the basement walls to crack and collapse.

Step 2

Use a shovel to remove mud off the basement floors. Dump the mud inside a bucket and discard outside your home. Rinse the basement floors with a water hose and direct the water toward the drain.

Step 3

Fill a bucket with 1 gallon warm water. Add 1/4 cup liquid dish soap and mix with a long-handled spoon. Dip a brush broom in the mixture and scrub the floors clean. Rinse the mixture off the basement floors with a water hose.

Step 4

Fill a clean bucket with 1 gallon warm water and add 1 cup oxygen bleach. Oxygen bleach is a safe alternative then chlorine bleach. Mix the contents together with the long-handled spoon until the oxygen bleach has dissolved.

Step 5

Dip a brush broom in the mixture and scrub the floors once again. Let the mixture sit on the basement floors for 10 to 15 minutes. The oxygen bleach mixture will kill any mold or its spores present on the basement floors. Rinse the floors clean with a water hose. Direct the water toward the basement drain.

Step 6

Place fans in the basement and let them run for several hours. The fans will help dry out the basement while providing better air circulation. Furthermore, run a dehumidifier in the basement to remove moisture from the air and reduce the risk of mold growth.
