Mold And Mildew On Exterior Of Home

When water sits on a shaded surface, especially one that is covered in small particles of dirt and environmental debris, fungi spores have the opportunity to grow. This spore growth produces visible mold and mildew.

If you have mold or mildew growing on your home’s siding, you will notice most of the stains on the north-facing side of the house or where landscaping has grown too close to the siding. These shaded areas and the north side of your house receive very little direct sunlight, which means that moisture does not have a chance to evaporate, the water just hangs around on your siding, creating the perfect habitat for mold and mildew spores.

Mold and mildew are both fungi. Mildew is usually gray, white, or yellow, although it can darken over time to brown. Mildew can be irritating to people, causing sore throat, coughing, and headaches; however, it is not usually as dangerous to respiratory health as mold is. Mold comes in many colors, from dark green to black. It can cause structural damage if left to grow unchecked. Mold is known to cause health issues, respiratory issues, and allergic reactions. Mold is easy to identify when you see it, but it can grow unseen for a while, that is why it is important to have your house treated/washed once a year.
