An estimated 26% of Australian homes have visible mould in areas other than the bathroom and need mould remediation, according to a review of 9 studies published in the Medical Journal of Australia in 2018.

​

“Moulds can grow on almost any surface,” says Prof Douwes. “Homes affected by water damage or leaks, rising damp, condensation on walls due to poor insulation and ventilation, and high humidity, are very likely to be affected by indoor mould unless leaks or indoor dampness problems are remedied promptly.”

 

Symptoms of a possible mould allergy may include:

​

• Running or blocked nose

• Irritated eyes

• Dry skin

• Sneezing

• Wheezing or a cough

​

People with pre-existing respiratory problems can also be sensitive to mould. According to Asthma Australia, when a person with asthma inhales mould spores, they’re at increased risk of an asthma flare-up.

 

Those with other respiratory issues, and compromised immune systems, may also be negatively affected by mould.
