Roof leaks and plumbing problems can lead to an outbreak of black mould growth in many houses. In adults, this can cause fatigue as well as eye, skin, lung and nervous system symptoms.

Health threat

Exposure to this mould has been associated with sometimes-fatal cases of bleeding lungs in infants.

Chronic water damage, such as a leaking roof or water pipe, encourages the growth of this fungus. (It's not the black stuff that grows on ceramic tile or grouting in your showers, but it may grow on walls or ceilings). Its favourite materials are wood, cardboard, paper, cotton cloth, lint, non-ceramic ceiling tiles and carpeting. Inhaling the spores may expose you to the toxins.

If your home has been water damaged, clean affected areas with bleach. Throw away waterlogged carpeting, books, photos, magazines or newspapers. To prevent any accumulation of moisture, follow these simple moves: When the temperature is cooler outside than it is inside, ventilate by opening windows. (Moisture migrates to colder surfaces). When it's hot and humid out-side, moisture will come indoors. So close the windows, especially if the air conditioner is on. Get into the habit- of turning on exhaust fans in bathrooms, basements and kitchens, and fix all water leaks promptly.
