Mold Inspection Edmonton

Mold can practically grow anywhere and everywhere, whether inside your house or on the outside. This organism typically thrives in damp and dark environments where temperatures range from 60°- 80° Fahrenheit. Some types of molds are considered to be dangerous. To understand which molds are dangerous and which are harmless, you must first know about the different types of molds in your house.


Alternaria is the most common type of allergenic household mold. It’s a velvet-textured mold with dark green or brown hair. It is often found in carpets, textiles, house dust, plant soil and potentially damp areas like window frames and showerheads. This large spore mold can get deposited in your nose, mouth, and upper respiratory tract to cause respiratory issues.


Aspergillus has more than 185 species and is present in different colors. It has long flask-shaped spores that can form thick layers or long chains of mold growth on surfaces. This type of mold is found in house dust, building materials, fall leaves, and other decomposing matter like compost piles. Aspergillus can lead to asthma attacks, lung infections, and respiratory inflammation. Certain Aspergillus species are capable of producing aflatoxins, a deadly carcinogen.


Cladosporium is the most commonly identified outdoor mold, but it can quickly enter the house through the HVAC system and other airflow passages. The indoor species of Cladosporium grows on textiles, upholsteries, wood and other porous, damp areas. It is an olive-green or brown-colored mold with a suede-like texture. Cladosporium typically causes allergic reactions to the eyes, nose, throat, and skin, skin rash and lesions, asthma, lung infections, and sinusitis.


Chaetomium has a cotton-like texture and usually changes colors from white to grey to brown and eventually to black over time. This mold is found in the wet or leaking roof, basement, sink, ducts, and pipes, and is recognizable by its musty odor. Chaetomium isn’t as dangerous as other household molds but can cause minor skin and nail infections.


Mucor is an allergenic mold that is white or grayish and overgrows in thick patches. It often grows near the HVAC systems and ducts due to moisture from condensation. Mucor can also grow on old, damp carpets and upholsteries. Mucor causes various issues in the respiratory system such as asthma, difficulty in breathing and flu-like symptoms including fever and malaise.


Stachybotrys, also known as toxic black mold thrives in warm, damp and humid conditions. It grows on cellulose material such as woods, cardboard, paper, hay or wicker. This mold produces airborne toxins (mycotoxins) that can cause serious breathing difficulties, memory and hearing loss, sinusitis, dizziness, flu-like symptoms and bleeding in the lungs.


Ulocladium is another black-colored mold that grows in moist places or places with stagnant water. It is typically found in homes and buildings that have experienced extreme water damage. Ulocladium may develop in conjunction with other mold types such as Stachybotrys, Fusarium, and Chaetomium.
