There are thousands of known species of moulds which include most common types such as Acremonium, Aspergillus, Cladosporium, Penicillium, Alternaria, and Stachybotrys (also known as “Black Mould”).

Although moulds grow on dead organic matter everywhere in nature, their presence is visible to the unaided eye only where mould colonies grow.  Moulds can grow on almost any substance when moisture is present. Mould is normally found indoors at levels that do not affect most healthy individuals. Mould spores may remain airborneindefinitely or may cling to clothing or furniture and may be able to survive extreme temperatures.

Mould growth in an indoor environment is typically related to water or moisture presence. Mould growth may also be caused by incomplete drying of flooring materials such as concrete flooding, leaky roof, building maintenance problems, or indoor plumbing problems.  Mould can be found in damp, dark, or steam filled areas such bathroom or kitchen, areas with poor ventilation, recently flooded areas, and outdoors in humid environments.

Exposure to Mould

Mould exposures have a variety of health effects depending on the person, some people are more sensitive to mould than others.  Exposure to mould can cause a number of health issues such as; throat irritation, nasal stuffiness, eye irritation, cough and wheezing, as well as skin irritation in some cases.

Some species of moulds produce mycotoxins that can pose serious health risks to humans and animals.  Studies claim that exposure to high levels of mycotoxins can lead to neurological problems and in some cases death.

Mould Inspection & Testing

We offer thorough mould inspections that involve visual examinations of the most likely areas to grow mould.  We also perform air sampling to assess the level of mould spores inside and outside your home.  If the air samples reveal that the indoor levels are significantly higher than the outside, it may mean that mould is growing inside your home.

These samples are taken by using a pump that forces air through a collection device which catches mould spores.

Taking air samples during a mould inspection is important for several reasons.  Mould spores are not visible to the naked eye, and types of mould present can often be determined through laboratory analysis of the air samples.  After remediation, new air samples are taken to help ensure that all mould has been successfully removed.
