Here is some information on the molds you may encounter within your residential or commercial property.


Typically this allergenic mold can be found in white and green colonies. At times it can be found in HVAC systems, but is most commonly found on wallpaper, carpet, and other fabrics, but produces an enzyme that is devastating to woods and paper. 


This is the most widespread mold and is classified as an allergenic mold. This mold is commonly found on porous materials or building materials and can thrive in many climates. This mold can affect the skin with rashes and irritation as well as cause allergy-like symptoms.


Aspergillus is an allergenic mold, but certain species are also pathogenic molds. There are over 100 species of this type of mold that come in all sorts of appearances and colors. This mold often causes allergic reactions with those who come in contact with it. Health effects range greatly depending on the individual’s immune system and respiratory system, and can be potentially very serious and lead to airway inflammation. The range of possible side effects or illnesses this mold can cause is referred to as aspergillosis. Some species are able to produce carcinogens known as aflatoxins, which are deadly. Due to their shape, this type of mold can form thick layers and potentially walls of mold.


Another allergenic mold, Alternaria has over 50 species. It is generally seen as dark gray spots, and is a common cause of allergy symptoms outdoors. When indoors, it generally needs a damp environment on woods, building materials, paper products, and textiles. This mold can spread rapidly and should be dealt with immediately to avoid any adverse side effects.


This is the infamous and toxic black mold. It often appears black or dark green with a slimy texture. Most commonly this mold is found on wood and paper goods. Moisture is mandatory for its growth so it is often found with water damage. Black mold creates mycotoxins, which have been proven to affect your immune system and can even cause cancer. Some side effects of black mold exposure include intense headaches, fever, allergy symptoms, stubborn cough, nose bleeds, and can trigger allergy symptoms.
