Take these steps to stop mould growing in your home before it starts.
We may encounter mould every day in things like spoiled food, wet windowsills or rotten wood. Mould can also grow in places we don’t notice, and can be particularly harmful when it grows where we don’t want it, such as inside homes.
Mould grows when it is provided with moisture, and daily activities, such as bathing or cooking, or water entering the house through cracks and leaks can contribute to an increase in moisture levels. When mould grows inside the home, it may affect the indoor air quality and pose a health hazard to individuals at risk. If you have a mould problem in your home, you will need a plan that includes dealing with existing situations and preventing future problems.
Whether you are an occupant, a housing manager, or a builder or renovator, CMHC’s Mould in Housing series may help you be better informed about mould-related issues as well as the ways to prevent and address them.
