The Culprits: Algae and Mold

The green stuff on your house is typically caused by two common culprits: algae and mold.

  1. Algae: Algae thrives in damp, shaded areas, often seen as green streaks or patches. While it may not be structurally damaging, it's unsightly and can tarnish your home's curb appeal.
  2. Mold: Mold, typically appearing as black or dark green spots, is more concerning. It can not only affect aesthetics but also pose health risks and lead to structural damage.


The Impact on Your Home:

The green invaders on your house can have several consequences:

  • Aesthetics: These stains are unsightly and can detract from your home's overall appearance.
  • Structural Damage: Over time, algae and mold can damage your home's exterior, potentially leading to expensive repairs.
