Why is there mould in my home?

Homes in your cooler climate zones are sometimes prone to significant condensation problems. Frequent condensation can cause mould to grow on surfaces in your home.

Condensation is caused when water vapour generally moves outward because outside temperatures are generally lower than inside and the internal humidity rises. Contributing factors:
    1. as occupants spend more time indoors,
    2. taking longer and hotter showers, and
    3. using mechanical clothes dryers or drying racks in front of heaters.

If you can manage the internal humidity in your home, you may be able to successfully seal all the gaps and maintain a healthy home environment. If not, you may be creating condensation, mould and adverse health problems.

Inhaling mould fragments or spores can inflame the airways, causing nasal congestion, wheezing, chest tightness, coughing and throat irritation.

Prolonged exposure to high levels of indoor dampness can reduce lung function and cause chronic health problems such as asthma. Those who already suffer from asthma and allergies are more likely to have more severe symptoms when exposed.

According to the World Health Organization (WHO), a considerable proportion of the world’s 300 million cases of childhood asthma is attributable to exposure to indoor dampness and mould.
