How does mould affect your health?

Moulds can cause eye, nose and throat irritation, coughing and phlegm build-up, wheezing and allergic reactions.

What causes moulds?

  • Water leakage from a roof or plumbing leak, or flooding.
  • Steam or moisture in the air from baths/showers, cooking and wet laundry.
  • Condensation on windows due to cold outdoor temperatures and high indoor humidity.

 Clean up small areas of mould yourself

  •  Use a cloth and liquid detergent
  •  Wear a mask, rubber gloves and safety glasses
  •  Fix the source of dampness so the mould won’t grow back again

Simple tips to keep your house free of moulds

  • Keep your air exchanger turned on for several hours a day – this will bring in fresh air from outside and get rid of stale air.
  • Turn on the bathroom fan for every shower or bath and keep it running for 30 minutes after.
  • Use your kitchen fan when you cook, and clean the fan regularly.
  • Buy a dehumidifier and keep it running in your basement all summer. Don’t forget to empty the water holder every couple of days.
  • Fix all water leaks quickly (within a couple of days).
  • Dry puddles and wet material within 24 to 48 hours using cloths and a fan.
  • Gyproc, carpets, wood or other materials that have been damp for a few days need to be thrown out and replaced. It only takes 48 to 72 hours for mould to start growing.
