What am I seeing on my exterior siding?

A stain on your home siding will constantly prevail, particularly without routine upkeep on your home. Part of the difficulty of discoloration is attempting to determine who the culprit is since there are a variety of different kinds. In this article, our goal is to inform you of the type of pollutants most commonly discovered on the side of your residence and what has a tendency to create them.

Common Stains on Exterior Siding


Dirt is the most basic discoloration you will see on your house. There are a lot of ways that dirt connects itself to your exterior siding, a few of which are brought on by the elements. For example, if there is a heavy storm with a great deal of wind, loosened dirt and mud can be blown onto the exterior of your house. The other way you can allow dirt to end up on your exterior siding is while you are landscaping or something similar around your home.


If you are seeing green stuff on your residence siding, primarily located on the northside of the house, it suggests that algae has attached itself to your exterior siding. Algae is among one of the most common contaminants that homeowners will see on their house. The origins of algae on outside residence siding are not always clear, yet one of the most common sources comes from bodies of water. As an instance, Lake Erie houses experience great deals of algal growing that is escalated by drainage into the lake. This air contamination allows the algae to feed and grow, then becomes airborne and begins to attach itself to and feed off the dirt on your exterior siding. While algae will not trigger any type of architectural damages, it can install itself right into the house siding if it is not properly pressure washed.

Mold and Mildew

Mold and mildew on the siding are caused by the buildup of moisture on the exterior siding. The opportunity of mold and mildew expanding on house siding increases when the moisture originates from a location of your home that obtains little to no sunlight. Like algae, mold and mildew feed off the dirt that is currently on the exterior siding. Both mold and mildew are fungi, nevertheless, they have different needs. Mold is mainly green and black in color while mildew tends to range from white to yellow. Mold and mildew need to be removed quickly as a result of the health risks it offers.
