If mold is a problem in the home, it must be removed for health reasons. Buildings that have become damp or wet because of heavy rains, roof leaks, floods, or plumbing issues must be cleaned and dried within 24 to 48 hours. Let rooms and buildings air out. Use fans to blow drier area through and clean all surfaces to prevent mold formation.
If mold does form, all surfaces must be cleaned or replaced. Absorbent materials such as ceiling tiles, furniture, carpet, or drapes must be replaced. Washing will not remove mold and the mold will return. Non-porous surfaces can be cleaned with water and bleach combinations or with detergent. Bleach and water can be a 50/50 ratio; less bleach to water ratios are sometimes used.
Mold prevents a health risk to anyone so if mold becomes a problem in your home, don't hesitate. Deal with the problem immediately before the situation grows even more serious.
