Having an attic in your home can be a great asset, providing extra storage space and insulation. However, if not properly maintained, your attic can become a breeding ground for mold. This can lead to serious health problems and costly repairs. The experts of attic mold removal in Toronto discuss five things that can turn your attic into a mold hotbed. Read on to learn more.

Poor Ventilation:

Air needs to be able to circulate through the attic in order to keep it dry and help moisture evaporate. This means that the attic should have an intake and exhaust vent, as well as having unobstructed soffit vents.

If these vents become blocked or do not have enough capacity for the size of the attic, then humidity can build up, leading to mold growth. The vents should also be checked regularly for blockages from debris or pests. To ensure proper ventilation, a professional may need to be consulted.

Humidity levels in the attic can have a major impact on the chances of mold growth. In order to keep mold at bay, you should aim to keep the relative humidity below 55%. High levels of humidity are a breeding ground for mold and mildew, which can be a major health hazard if left unchecked. The best way to reduce the humidity in your attic is to install a dehumidifier and maintain it regularly.


Leaks can be a major cause of mold growth in the attic, as they allow moisture to enter the area and create dampness. Even small leaks can be a source of moisture, since these can accumulate over time.

To prevent mold growth, it is important to inspect your attic for any potential sources of leaks, such as damaged or missing shingles, cracks in the roof, and even improperly sealed windows or doors. To further reduce the chances of mold growth, repair any leaks that you find as soon as possible.


Clutter provides a perfect hiding spot for the mold to grow and spread, as well as providing the perfect source of food for the mold to feed off of. Clutter in your attic can range from old boxes, furniture, clothes, books, magazines and anything else you might have stored away.

The moisture and darkness provided by the clutter provides the perfect breeding ground for the mold to thrive and spread. To prevent the growth of mold in your attic, it’s best to keep it clear of clutter and thoroughly clean any existing clutter regularly.

Poor Insulation:

When insulation becomes wet or damp, it can easily become a breeding ground for mold and mildew. Additionally, inadequate insulation can create cold spots in your attic that can cause condensation on walls and ceilings, leading to further mold growth. To help avoid this issue, check your attic insulation and look for any areas that need to be replaced. If the insulation is old, consider replacing it with newer, more effective insulation material.

Are you concerned about the risk of mold growth in your attic? Whether you’re a homeowner, a renter, or a landlord, it’s important to be aware of the conditions in your home that can increase the chances of mold growth in your attic.
