Here is a great example of what mold looks like when it is growing in your home. Mold can appear anywhere. The growth occurs where there is moisture that does not dry. It is a good idea to have monthly check around your home where there could be possible water leakage issues, such as around the air conditioner, around the sinks, around the bathroom faucets, around the washing machine and around the toilet. These are not the only places you should check, but keep an open mind and make sure you are paying attention to signs of mold and mildew in your home.
