Mould is a home and business owner’s worst nightmare. Mould is a type of fungus that grows both inside and out but causes most of its damage when it spreads indoors. Mould spores can be inhaled by humans and the smaller the spores, the farther they can travel down people’s lungs. According to a CBC report, most healthy people aren’t affected by mould. However, infants, children, pregnant women and people with weak immune systems are particularly susceptible. Common problems include:

  • Coughing
  • Wheezing
  • Irritated lungs
  • Headaches
  • Fatigue

Mould Locations—The Usual Suspects

Despite owners’ best efforts, homes and businesses are often breeding grounds for mould. That’s because the interior of buildings provides plenty of fertile areas for mould to grow.


Water is mould’s most obvious enabler, especially in large amounts, such as a flood. Flooding can cause severe damage to a home or business in a short amount of time. As it saturates drywall, wood, and carpets, mould can develop quickly, often within 24-48 hours. This is particularly problematic for businesses, as they may experience downtime.

Leaky pipes are a common source of mould, albeit a less obvious one. If missed, pipe leaks can cause serious damage because they often occur behind walls, allowing mould to spread rapidly. To avoid this, you should have your pipes checked regularly by a certified professional.

Bathrooms and Kitchens

Humidity—or the amount of moisture in the air—can accelerate mould growth and cause significant damage. Bathrooms and kitchens act as rich grounds for mould growth due to the showering and cooking of occupants. Additionally, humid temperatures and lots of rain can raise the humidity levels inside your home, allowing mould to do its dirty work.

Insufficient ventilation in a home or business can work hand-in-hand with humidity to spread mould. Therefore, it is crucial to ensure proper ventilation by opening windows or even using fans whenever possible.

Roofs, Attics, and Basements

The actual structure of your home or business can also contribute to mould growth. Roofs are often the culprits. Leaks in your roof can result in water stains on the ceiling—a telltale sign of a problem. Attics are also suspect, as they are under the roof and can act as a refuge for mould spores to grow. It is a good idea to have your roof and attic inspected regularly for any damage or leaks.

From the top to the bottom of a structure, the basement is another prime suspect when it comes to mould growth. Basements are often dark, damp, and poorly ventilated, and as such, are perfect spots for mould to grow unchecked. Basements are also more prone to leaks and flooding, especially since they often house piping.
