Common Types of Mold
While there are thousands of different mold species, mold remediation professionals rarely think of mold outside of these four major categories.
Homeowners call us most frequently about black mold removal, which isn’t surprising. Black mold is very unappealing to look at, and even a quick Google search will reveal that it can be toxic. Black mold includes aspergillus, stachybotrys and cladosporium. This is the mold that is most likely to trigger health issues. It often causes symptoms that mimic those of allergies or asthma. You may experience red eyes, sore throat, and even rashes. It’s important to act quickly when you spot black mold.
Green mold tends to appear first as dark spots and then later morphs into a distinctly green fuzz if not quickly addressed. Like all mold, green mold grows in moist environments. Classifications of green mold may include cladosporium, aspergillus, penicillium, or Alternaria, the most common allergenic mold in the world. The symptoms of green mold exposure are no different than the symptoms of exposure to any other mold.
Orange mold is more commonly located outside and can appear more slimy than fuzzy. Orange mold grows very quickly and aggressively in wood, meaning that it is likely to be found on floorboards, ceiling beams and even your foundation. Walls that are exposed to highly acidic water, also known as hard water, are prone to developing orange mold.
White mold looks very similar to a phenomenon called efflorescence. Efflorescence is a crystalline growth that occurs when water moves through a material and raises unbound salts to the surface. The growth is harmless and appears white and fluffy. While it looks very similar to white mold, it has a different chemical makeup. Efflorescence will typically dissolve right away when water is applied. It is also odorless, which is another big point of distinction from white mold. Additionally, there are some differences in the environments where you may expect to find efflorescence or while mold. Because it originates from relocated salts, efflorescence only occurs on concrete, brick or masonry. White mold grows easily in spaces like crawlspace framing and attic sheathing.
At Bright Restoration, or policy is to treat all mold aggressively until it has been completely removed. Even mold types that are considered non-toxic can produce adverse effects, so we remove all signs of mold regardless of the color.
