Water damage can be a nightmare for any home or workplace. Bad enough that the unwanted water can not only damage your home’s interior walls, ceilings, and floors, but it can also wreak havoc on your furnishings and personal possessions. 

The aftermath of water damage can also be a long-term problem that affects your home’s safety and the health of you and your family.

In this article, we’ll discuss some of the many types of mold that can grow in your home as a result of water damage.

When wood, drywall, concrete, and other building materials get wet and stay wet for more than a few hours, they become a breeding ground for millions of different types of organisms.

The vast majority of these lifeforms are entirely harmless and so small that they’re never even seen. One type, though, can turn your home into a health hazard: mold.

What is Mold ?

Before we start to talk types of Mold, what is Mold? Mold is a common and often troublesome problem in homes that have experienced water damage. In Denver CO, where the climate can be humid and rainy seasons are prevalent, mold growth can be a significant issue.

Mold not only damages property but also poses health risks, making it essential to understand the types of mold that can thrive in water-damaged homes. 

This comprehensive guide will discuss four common types of mold found in such environments: Stachybotrys chartarum (Black Mold), Aspergillus, Cladosporium, and Aspergillus. Each type will be explored in detail, including their characteristics, health effects, and prevention methods.

This species is the most feared common mold, responsible for the vast majority of mold-related severe health problems and deaths. While it’s commonly referred to as “black mold,” Stachybotrys can be greenish, grey, or even orange in tint.

It’s a slimy mold that usually looks a bit like tar. In addition to allergies and other problems caused by breathing in the spores from black mold growth, the fungus also releases some toxic chemicals called mycotoxins that can cause severe respiratory and neurological conditions and other significant health problems.

Black mold usually hides inside your walls, so it is notoriously difficult to detect. If you suspect your walls might be infested, it is best to contact a professional because removing the mold requires respirators, personal protective equipment, and other specialized mold safety equipment.

Cladosporium | 4 Types of Mold

More commonly found on mineral surfaces like tile, concrete, and drywall or furniture and fabrics, Cladosporum starts as tiny black, yellow, or green dots that grow until they merge into a large patch of brownish-black and olive-green growth. Breathing in Cladosporium spores can cause severe allergies and asthma in people with a sensitivity to molds.

Cladosporium most often appears in bathrooms, sinks, and bathtubs. It can also be found on damp furniture and carpets, especially those that suffered water damage and weren’t dried well.

Aspergillus | 4 Types of Mold

While typically harmless to most people, the spores of Aspergillus molds can be dangerous when inhaled by people with lung disease or a weakened immune system. The spores can cause infections in the lungs and other organs that these individuals may not be able to fight. 

While Aspergillus is also black, it has white and yellow spots that make it easily distinguishable. This variety is not as toxic as most others, and a lot of people can breathe in spores without having any symptoms.

Alternaria | 4 Types of Mold

Alternaria grows thick and has an almost velvety surface that sometimes has long, hairlike projections. While more common in the outdoors, Alternaria can thrive inside a home’s basement, crawlspace, or attic and can cause severe respiratory distress for asthma and allergy sufferers.

How do I know which type of mold my home has?

If you can see the mold, you can usually identify it by its appearance, and there are dozens of sites online with photos of different molds that you can compare. Molds don’t always grow out in the open, however, and you may need to rely on some other cues to tell you that your home has developed a mold problem:

  • Smell: Most molds will put off a musty or even a foul odor like rotting vegetables.
  • Dust: When molds release spores, your home can be filled with persistent, musty-smelling dust that is hard to get rid of.
  • Health effects: If you and your family or people visiting your home begin to show allergy or asthma symptoms that clear up when they leave, that may indicate a mold problem.
