Understanding Mould: Types, Causes, and Common Areas of Growth in Homes

Understanding Mould: Types, Causes, and Common Areas of Growth in HomesMould is a type of fungus that grows in tiny, thread-like structures called hyphae. Mould spores are present in all indoor environments, but mould growth can be prevented. The key to mould prevention is moisture control. Mould has been found throughout history, and for many ancient cultures, mouldy bread was a common remedy for some ailments.

Types of Mould

Common types of indoor mould include Cladosporium, Penicillium, Alternaria, and Aspergillus. These can appear as black, green, or grey spots on the walls, ceilings, or other damp surfaces in the home. “Toxigenic” mould can cause serious health issues.

Causes of Mould Growth

Mould requires moisture, oxygen, a food source, and a surface to grow on. Cellulose (the end product of photosynthesis in plants and the most common organic compound on earth) is a common food source for indoors mould. High indoor humidity enables mould to grow rapidly.

Common Areas of Mould Growth

Mould most commonly grows in places that are prone to moisture, such as basements, kitchens, and bathrooms. It can also grow in places you might not expect, including air conditioners, ducts, plumbing leaks, and behind wallpaper.

Health Risks Associated with Mould Exposure

Health Risks Associated with Mould ExposureMould exposure can lead to a variety of health concerns, ranging from mild to severe. Prolonged exposure, especially to those with pre-existing health issues, can be particularly dangerous.

Respiratory Problems

Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes, and skin rash. Mould can also trigger asthma attacks in those who are asthmatic.

Allergies

Mould is one of the most common triggers for allergies. Symptoms include nasal stuffiness, eye irritation, wheezing, or skin irritation. Severe mould exposure can also lead to more serious conditions like hypersensitivity pneumonitis, which resembles bacterial pneumonia.

Other Health Conditions

Some people, particularly those with weakened immune systems, may be at higher risk of lung infections. Mould exposure might also contribute to the development of chronic conditions such as obstructive lung diseases or fungal infections of the skin or nails.

Signs of Mould in Your Home

Health Symptoms

If you experience any of the allergic or respiratory symptoms listed above and they worsen when you’re at home, mould may be to blame. It’s especially important to look for signs in areas with poor ventilation, where a previous water leak has occurred, or where flood damage has been repaired.
