Mould can be surprisingly hard to recognise. It comes in many colours and textures, and it looks different depending on the surface it’s growing on. Because it’s often mistaken for dirt, stains, or discolouration, it can spread for a long time before anyone realises what it is. Here’s how to spot mould on the surfaces where it commonly appears.
Where Does Mould Grow?
Mould grows wherever there is moisture, warmth, and a food source. That means damp basements, bathrooms, kitchens, attics, and anywhere that has experienced leaks or water damage are all prime locations. It also hides in less obvious places, like behind walls and under carpets.
What Mould Looks Like on Different Surfaces
On Wood
On wood, mould often appears as black, green, or white fuzzy patches, sometimes with a powdery texture. It can also cause discolouration and a musty smell.
On Drywall
Mould on drywall usually shows as dark spots or fuzzy growth, and because drywall is porous, the mould often penetrates deep, meaning the surface stain is just part of the problem.
On Carpet
Carpet mould may appear as discoloured patches and is often accompanied by a persistent musty odour. It frequently grows underneath, out of sight, after moisture soaks in.
On Walls
On painted walls, mould can look like black, green, or brown spots that may spread outward, sometimes with bubbling or peeling paint nearby.
On Ceilings
Ceiling mould often signals a roof or plumbing leak above, appearing as dark rings or fuzzy patches, commonly in corners and around fixtures.
On Bread and Food
On food like bread, mould is easy to spot as fuzzy green, white, or black growth, a familiar reminder of how quickly mould can develop in the right conditions.
On Concrete
On concrete, mould can appear as black, green, or white staining, often in damp basements and garages where moisture collects.
On Clothes and Fabric
Mould on fabric shows as fuzzy spots and a musty smell, typically on items left damp or stored in humid conditions.
