Frozen Mold
Mold grows best in warm humidified weather. But that does not mean that it can not grow in other types of climates. For example: at this place of business, they had mold growing in the freezer. Your home freezer and a business freezer are really no different than one another. One of the reasons why mold was able to grow here is because it is dark within a freezer and there is always some form of moisture; two key ingredients for mold growth.
As any good business would do, they called SERVPRO to remove the mold issue immediately; and the business was back up and running in no time!
