Mould is a potential health hazard that can cause significant structural damage to your property if left untreated. For Perth homeowners, the wet winter months create ideal conditions for mould growth. Recognising the early warning signs and understanding the facts of mould can save you from costly mould remediation and protect your family’s health.
1. A Musty Odour
One of the earliest indicators of a mould problem is a distinctive musty smell. If you notice a persistent earthy, damp odour in certain areas of your home, particularly in humid areas like bathrooms and laundry rooms, or dark places like basements, this could signal hidden mould growth. This smell often precedes visible signs, so do not attempt to mask it with air fresheners but investigate promptly.
2. Visual Mould Indicators to Watch For
Discolouration on walls, ceilings, or floors is a clear warning sign of mould. Look for:
- Yellowish stains that gradually darken to green or black
- Bubbling or peeling paint
- Watermarks or rings on surfaces
- Warping of wooden materials
These visual cues often appear in areas with moisture issues, such as around windows where condensation forms.
“If left untreated, mould can escalate and permanently damage the structure of your home.”

- Unexplained allergic reactions
- Persistent coughing
