The first step in solving an indoor mold problem is stopping the source of moisture. Next is to remove the mold growth. Common remedies for small occurrences of mold include:

• Sunlight
  
• Ventilation
• Non-porous building materials
• Household cleansers

Significant mold growth may require professional mold remediation and removal of affected building materials. A conservative strategy is to discard any building materials saturated by the water intrusion or having visible mold growth.

There are many ways to prevent mold growth; see ventilation issues in houses.In extreme cases of mold growth in buildings, it may be easier to condemn the building rather than clean the mold to safe levels.

Certain contractors are capable of repairing mold damage - usually by removing the affected areas and eliminating the cause of the excess moisture.

There are also cleaning companies that specialize in fabric restoration - a process by which mold and mold spores are removed from clothing to eliminate odor and prevent further mold growth and damage to the garments.

Improper methods for cleaning mold include exposure to high heat, dry air, sunlight (particularly UV light), ozone, and application of fungicides. These methods may render the mold non-viable, however, the mold and its by-products can still elicit negative health effects. As noted in following sections, the only proper way to clean mold is to use detergent solutions that physically remove mold. Many commercially available detergents marketed for mold clean-up also include an anti-fungal agent. The most effective way at this point is formal Mold Remediation.
