Mold removal from home in Burnet, TX
The before picture is an example of a room where moisture, over a period of time, allowed mildew/most to grow. It usually takes about 48-72 hours in the right environment for mildew/mold to grow which is why it's so important to get the drying process going as soon as possible to prevent these types of situations.
These homeowners were fortunate that their insurance company worked to cover this. This was a water loss that had gone unchecked until a neighbor noticed water coming out of the residence. Most insurance companies won't cover mold or mildew under their policies anymore.
