Visible mould is a sign that moisture has been present long enough for growth to develop. It may appear as black, green, grey or white patches around windows, ceilings, bathrooms, wardrobes or walls. A musty smell can also indicate a hidden issue.

The right response is to take the growth seriously without spreading it through unnecessary cleaning or disturbance.

Start by looking for the moisture source

Mould needs moisture to grow. Check for recent leaks, condensation, poor ventilation, roof damage, plumbing issues or wet materials after flooding. The location of the mould can provide useful clues: window mould may relate to condensation, while ceiling mould may point to a roof or plumbing leak.

Finding and fixing the moisture source is essential. Without it, mould can return after cleaning.

Limit disturbance of affected areas

Avoid dry brushing, sanding or scraping obvious mould. These actions can spread spores and debris. Keep children, pets and other occupants away from heavily affected areas where practical.

For larger areas, recurring growth or mould linked to water damage, arrange a professional inspection before attempting a DIY solution.

When professional PPE is needed

Professionals use appropriate protective equipment when inspecting or remediating mould-affected areas. Depending on the conditions, this may include disposable coveralls, gloves and respiratory protection. PPE helps reduce exposure while the extent of the issue and the moisture source are assessed.

The work method should also include containment and careful cleaning where needed, especially when affected materials are being removed.

Consider the people using the property

Damp and mouldy environments can aggravate respiratory symptoms and may be of particular concern for people with asthma or allergies, young children, older people and people with weakened immune systems. If the area is extensive or the property has a persistent dampness problem, prompt assessment is a sensible step.

A professional can help determine whether materials can be cleaned, dried, repaired or need replacement.

Visible mould is not something to ignore or simply paint over. Address the moisture, avoid spreading the growth and seek professional advice when the issue is extensive, recurring or linked to water damage. Hazmat Detection & Removal provides mould inspection and remediation support across NSW.
