What is Mould
Small spores. Big problems. Understanding mould in your home.
Mould is a type of fungus that grows in damp or humid environments. In homes and buildings, it develops when excess moisture meets organic materials such as wood, drywall, or insulation.
Once established, mould can spread quickly through spores, often hidden behind walls, under your structure or under flooring.
Even small amounts of moisture; from condensation, leaks, or poor ventilation; can allow mould to take hold. Over time, this can lead to structural damage, unpleasant odours, and potential health concerns for occupants.
Understanding where mould forms, how to recognize it early, and what conditions allow it to thrive is the key to prevention.
