Identifying and Preventing Mold
Mould can enter the home in many ways, doors, windows, clothing, pets, etc but mostly i'ts the consequence of moisture entering through unseen leaks. Some mould growing may not be a problem. For instance, you might see mold around windows which is easily cleaned away. This indicates that there is too much moisture in the home.
Mould can be different colors and may look like a household stain. One way to test the spot to determine if it is mould is to put a drop of bleach on the stained spot. If the spot loses its color and disappears, it could be mould. Sometimes when moulds are present there is a musty or earthy smell.
Moulds can damage and discolor household materials leaving them ruined. Cardboard boxes and paper can deteriorate if they have mould on them and clothing can become permanently stained. Also mold can lead to wood rot or the growth of fungi. But the most serious consequence of mould is the danger it presents to health.
