Mold is a familiar condition in many homes. Wetter areas of the country have moldier homes, and even homes in dry areas have certain mold remediation rooms and spaces that are more prone to developing mold.1
Where there is moisture in a home, there is undoubtedly mold. The most familiar example of mold is the type that develops in the grout between ceramic tiles. A simple form of homeowner-driven mold remediation happens each time you spray that mold down with a bleach-based cleaner and wipe it off. More critical mold, either from a safety or aesthetic standpoint, happens elsewhere.
All places where water is found can develop mold. An excessive amount of humidity in a house can condense and cause mold. Ironically, newer homes can often experience more mold growth than older homes because they are more tightly insulated
