The dangers of mould

The dangers of mould

Mould is a form of fungus that can develop on any could surface in humid environments. It can grow on your walls, windows, and so many more areas of your home. If left unattended, mould can spread quickly and get deeper into the surfaces it is latched on to.

Mould is commonly found in homes in two forms. That being said, there are multiple other forms of mould that have other characteristics that can affect you.

  • Black Mould – Also called Stachybotrys chartarum, black mould is commonly found in bathrooms and wet rooms but can also occur on cold exterior walls in habitable rooms such as the bedroom or living room.
  • Cladosporium – Commonly found in bathrooms, under sinks, and around taps, but it can grow on surfaces like carpets, furniture, walls, and floors.

Mould reproduces from tiny spores. The spores float through the air and deposit on the surfaces. Under adequate temperature, moisture, and nutrient conditions, the spores can form new mould colonies.

Once mould gets in to surfaces deeper, it can be extremely difficult to remove it. This is why it should be removed as soon as it is spotted. Here are the ways mould can be formed.

  • Condensation, or other wet surfaces, are not wiped and dried down.
  • There is an unfixed leak that is dripping on an area constantly.
  • Another mouldy object has been brought into the home and left there.
  • There is no effort to ventilate the home.
  • Windows and extractor fans are not used when taking a hot shower or bath.
  • Windows are not open, and cooker hoods are not used when cooking in the kitchen.
