Common Types of Mold Growth Caused by Water Damage



Mold are organisms that thrive in damp areas – or anywhere with excess moisture. They are an important part of the ecosystem, breaking down organic matter and helping to enrich the soil plants grow in. However, mold’s ability to destroy organic matter also makes it a problem, especially if found inside your home.


A recent estimate suggests that there are at least 100,000 species of mold present around us and in our homes. While not all species of mold are toxic or dangerous, some species release mycotoxins which are harmful to the body. If you or someone you know has mold sensitivity, you may encounter symptoms such as:

· respiratory congestion

· coughing

· sneezing

· eye irritation

· skin rashes

· headaches


Prolonged exposure to mycotoxins may also lead to more severe health conditions, including cancer, pulmonary fibrosis and neurotoxicity.

If you’re dealing with water damage, below are some of the mold species commonly found inside buildings:

1. Aspergillus

This type of mold appears in long chains of flask-shaped spores. Colonies are often found growing on walls, PVC/wallpaper covering, gypsum boards, carpet and mattresses, HVAC insulation, filters and fans – and even on upholstered furniture, shoes and leather.

2. Chaetomium

Chaetomium is often mistaken for black mold, mainly because they share some similar characteristics and like to grow in the same types of conditions. This type of mold is typically found in wet and dark environments like baseboards, drywall and under carpets or areas where there is water damage. It has a fluffy cotton-like texture and comes with an unmistakably strong, musty odour.

3. Penicillium

Penicillium molds are known for their distinct odor and rapid growth. They usually appear in shades of green, blue-green or grey-green, but some are white, yellowish or pinkish. They have a velvety to a powdery texture. Penicillium colonies may be found growing in water-damaged materials such as plywood, wallpaper, behind flaking paint, under carpets and mattresses or in fiberglass insulation. They are also found in unprotected food products such as cheese, fruit, cereals and spices.

4. Alternaria

Alternaria is the most common type of allergenic mold. It has a velvety texture and appears as dark green or brown hairs. They are typically found in showers, bathtubs and under sinks. They may also grow on horizontal surfaces such as window frames, carpets and textiles.
