Mould

What is it? 

Mould is a naturally occurring microscopic fungus. Indoors, it can especially develop in humid, poorly ventilated areas such as kitchens, bathrooms and places where water has leaked, as well as after a flood.

Mould can be identified by the stains it causes (often white, green or black), a musty smell or signs of water infiltration or high humidity (e.g., swelling, water stains), which can indicate its presence inside walls or above ceilings.

Health effects

On small surfaces and when cleaned quickly, mould generally does not cause problems. However, if it spreads, it can release particles in the air which can cause health problems.

Mould does not affect everyone. Some possible symptoms include a runny nose, cough, asthma, respiratory infections and irritations of the eyes, nose, throat and skin.

The persons most at risk are those with allergies, respiratory disorders (for example, asthma) or a weakened immune system, as well as elderly persons, babies and pregnant women.

How to prevent mould

  • Keep the home well ventilated as much as possible.
  • Turn on the fan during and after a shower and use the kitchen hood’s fan when cooking.
  • Quickly locate and repair water spills or leaks.
  • Leave a space of a few centimetres between outside walls and furniture to allow air circulation.
  • Install beds on a platform or frame to ensure air circulation under mattresses.
  • Wipe up any water accumulated around the bath and sinks after use; do the same with water around windows and other areas.
  • As soon as any traces of mould appear (for example, black stains), clean with soapy water and dry completely.

*** In case of spreading mould or traces of water infiltration, inform the organization or the person in charge of building maintenance without delay.

*** In case of health problems, call Info-Santé at 811 or consult at your CLSC.
