Mould Presence Inspection in Bentleigh

In Bentleigh, we often see mould in bathrooms with older waterproofing, laundries with slow leaks, and around windows where condensation builds up. For homes with timber floors, accessible subfloors can also show mould on framing when ventilation is limited or ground moisture is high. Roof spaces may show mould staining after minor roof leaks or if bathroom exhaust air is venting into the ceiling cavity.

Yes. Renovations can introduce new moisture loads and change airflow patterns. Common problems include exhaust fans that don’t vent outside, wet-area waterproofing defects, and junctions where new extensions meet older walls. New paint or silicone can temporarily hide staining, but it won’t address the underlying moisture source. An inspection helps confirm whether the renovation work is performing as intended.

Staining can be from dirt, soot or old water marks, while mould is a biological growth that often appears as speckling or fuzzy patches and may produce a musty odour. The key is the conditions around it—persistent humidity, condensation or leaks. During the inspection we look at the pattern, location and surrounding moisture indicators to determine whether the marks are consistent with active or recurring mould.

They can, particularly if subfloor ventilation is poor, the under-house area stays damp, or wet areas haven’t been upgraded properly. Older homes may also have gaps that allow moisture-laden air to move into wall or floor cavities, then condense when temperatures drop. We focus on underfloor conditions, wet areas, and external-wall rooms where these properties commonly show early mould activity.

First, address the moisture source—leaks, ventilation, drainage or condensation drivers—otherwise mould is likely to return. For small surface areas, cleaning may be appropriate, but larger or recurring issues often require professional remediation and sometimes repairs to waterproofing, exhaust ducting or damaged linings. Our report outlines the affected areas and the most likely causes so you can brief the right trades and scope works correctly.
