Types of Mold That Grow In Homes

Residential Mold Remediation
 

Mold is a fungus that grows in tiny filaments. Molds are a large and diverse family of living microbes which are generally invisible until they breed into colonies which have a discolored, fuzzy, or dusty appearance. Each colony can be considered a single organism.

Infestation and Risks

Mold feeds on organic matter and reproduces by giving off spores. These can be airborne and become a component of household dust. In the home, mold usually forms on surfaces where there’s high moisture. We’ve found that it can thrive anywhere, including non-visible areas such as inside cabinets, attics, basements, ductwork, carpets and wall spaces.

Mold can cause extensive property damage. A thriving mold colony also poses health risks, producing toxic compounds that can be inhaled or ingested. The toxins from some molds can cause respiratory problems, neurological damage, and even death. Many people can be highly allergic. Our mold remediation experts at Lime Green Restoration can help.

Types of Mold

While there are thousands of mold species around the world, we can identify a few common types that we feel homeowners should be particularly alert for.

Aspergillus

This is a widespread mold found inside homes. It can cause respiratory infections, including pneumonia, and allergic problems. It is often found inside AC systems so that it’s spread throughout the home and can infest exposed foods. Aspergillus can even grow inside mattresses or pillows in excessive humidity. Colonies are usually a blackish-yellow in color.

Cladosporium

It infests porous surfaces like wood or fabrics, but can also thrive on very smooth surfaces such as toilet or bath fixtures, fiberglass ventilation components, and painted drywall. This mold is usually a black or green color with pepper-like particles. While it’s considered a non-toxic species, prolonged exposure to it can still produce allergic reactions such as difficulty breathing, eye irritation, and a sore throat.

Stachybotrys Chartarum

Stachybotrys Chatarum, otherwise known just as black mold, colonies have a very dark, shiny appearance. It also gives off a distinct, musty odor. It is a known source of dangerous mycotoxins. This mold is usually found in places that are damp all of the time, such as walls or floors where they are dripping pipes or AC components.

Other common types of mold:

  • Aureobasidium: Usually found outdoors, it can also spread to the interior of homes. Pinkish black in color, it’s often found around window frames and caulking and grows on wood, wallpaper, and even painted surfaces. Though non-toxic, it produces allergic reactions in a large number of people.
  • Penicillium: Sometimes found alongside aspergillum, this mold is green or blue-colored, and while non-toxic, it is also a respiratory irritant that leads to infections and can spread very quickly.
  • Serpula Lacrymans: This is a yellow-colored mold that, while non-toxic to humans, grows and feeds on damp wood, causing dry rot and structural damage.
  • Ulocladium: This is a fast-growing mold that requires lots of water, so it frequently appears as a consequence of flood damage. It can be brown, green, or grayish black in appearance, but has a suede-like texture. It can cause respiratory conditions as well as skin and eye infections, plus irreversible damage to wood, drywall, and other porous materials.

Our technicians can identify the particular type of mold that’s infesting a home, determine the cause, and recommend the best course for restoration from the damage and safety risks that mold causes. Often, this depends on the surrounding conditions and the severity of the infestation. For homes that have experienced water damage or begin to emit musty odors, the safest course of action is to call one of our professionals in for an inspection of the home.
