Ten Things You Should Know About Mould

Potential health effects and symptoms associated with mould exposures include allergic reactions, asthma, and other respiratory complaints.
There is no practical way to eliminate all moulds and mould spores in the indoor environment; the way to control indoor mould growth is to control moisture.
If mould is a problem, then it must be cleaned-up and sources of moisture eliminated.
Fix the source of the water problem or leak to prevent mould growth.
Maintain indoor humidity (to 30 - 60%) to decrease mould growth by:
- Venting bathrooms, dryers, and other moisture-generating sources to the outside.
- Using air conditioners and dehumidifiers.
- Increasing ventilation.
- Using exhaust fans whenever cooking, dishwashing, and cleaning.
Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mould growth.
Clean mould off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are mouldy, may need to be replaced.
Prevent condensation – Reduce the potential for condensation on cold surfaces (such as windows, piping, exterior walls, roof, or floors) by adding insulation.
In areas where there is a perpetual moisture problem, do not install carpeting (such as on concrete floors with leaks or frequent condensation).
Mould can be found almost anywhere and can grow on virtually any substance providing moisture is present. There are moulds that can grow on wood, paper, carpet, and foods.
