Many types of mould exists and can create serious health problems for the occupants. Poor ventilation and wet/damp areas are the main issues for mould to exist.

Brent Heness Pre Purchase Inspections provide information in identifying mould in our Pre- Purchase Inspection Reports.

Mould may grow indoors in wet or moist areas lacking adequate ventilation, including walls/ wallpaper, ceilings, bathroom tiles, carpets, insulation material and wood. If moisture accumulates in a building mould growth will often occur and can affect the buildings performance.

How can I prevent ​mould from growing in my home?

Although mould can be found almost anywhere, it needs moisture and nutrients to grow. The key to preventing mould growth is reducing dampness in the home. This can be done by:

Maintaining proper v​entilation
  • Turn on exhaust fans, particularly when showering, cooking, doing laundry or using the drying clothes.

  • Open windows when weather permits, to improve cross ventilation.

  • Open blinds/curtains allowing sunlight to the interior

Reduce hu​midity levels
  • Limit the use of humidifiers.

  • Limit the number of indoor plants

  • Limit use of unflued gas heaters

Controlling m​oisture and dampness
  • Repair all water leaks and plumbing problems e.g. water heater /air conditioner overflow pipes, leaking downpipes/gutters, leaking roof or blocked gutters.

  • If water enters your home, completely clean and dry water-damaged carpets and building materials. Discard material that cannot be cleaned and dried completely

What are p​ossible health problems from contact with mould?

In order to reproduce, mould produces tiny particles called spores. Spores are carried in the air and may cause health problems if inhaled by people who are sensitive or allergic to them.

For people with asthma, inhaling mould spores may cause an asthma attack.

If you or your family members suffer health problems after coming into contact with mould, contact your doctor. In the case of a life threatening emergency, phone 000.
