What’s growing on my home?

Many nasty organisms grow around your home.

Lets get to know a few and why.

Organisms growing on your home have a few things in common.  They’re there because:  

  • Moisture.  High moisture environments from humidity, low air-movement and poorly draining areas are major influences.
  • Shaded.  Organisms typically don’t do well in direct sunlight.  Sunlight also dries them out.
  • Hungry.  Nutrients come from indirect sunlight, fertilizer, pollen/tree sugars and other various sources. 

You will generally find these add up for the growth to appear largely on the northern exposures of your home.

Algae

Seen as a green, film-like substance, algae can bloom across your home relatively quickly.  Algae serves as a host (food source) for larger, more problematic organisms.  

Bacteria

Bacteria is the culprit for making roofs appear streaky.  Typically, associated to roofs, it can also be found on stone and concrete.  It feeds on the minerals in rocky matter.

Lichens

Lichens are a group of unique organisms that can survive in the most extreme conditions.  They are commonly confused with algae and moss.  Lichens develop small roots to feed and secure their selves to the surface.  The article image above shows multiple species of lichen on wood.  

Mildew and Mold

One of the same, this fungus grows in shaded areas with high moisture.  Concrete and brick are great incubators for mold where it receives nutrients from your lawn. 

Moss

Moss grows in shaded areas kept moist or soils that poorly drain.  Moss roots into materials and is a concern for surface damage when found on building materials. 

Artillery Fungus

Artillery fungus is a harmless fungus that thrives in your mulch.  It spreads by shooting tar like balls onto adjacent surfaces (up to 20 feet!).  At only 1/10th of an inch, the tar balls are not too visible.

Pollen

This powdery substance blows onto our exteriors.  Pollen becomes sticky where it begins to collect dirt and other airborne particulates.  Many organisms feed off of the nutrients in pollen.

Tree Sugars

Tree sugars are sticky substances commonly related to maple syrup.  Dirt gets stuck to the sugar residue causing the surface to become covered.

We come across many different contaminants, organisms and stains as we clean on customers homes.  Lead Dog knows how to tackle all issues you face around your property.
