Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect bathrooms, ensuites, laundries and kitchens for visible growth, staining and musty odours, with close attention to grout lines, silicone edges, vanity kickers and behind/to the sides of fixtures where moisture lingers.
We check likely condensation points such as window reveals, sliding door tracks and corners of external walls, and assess the practicality of existing ventilation (exhaust fan placement, ducting, and airflow) because poor air exchange is a common driver of recurring mould.
Where access allows, we examine wardrobes, linen cupboards and areas behind large furniture positions for signs of trapped humidity and mould spotting—common in bedrooms and robes that back onto cooler external walls.
For Box Hill homes with raised floors, we inspect subfloor ventilation, damp ground conditions, and signs of fungal growth on bearers/joists. Restricted airflow and damp soil can feed mould and mildew that migrates into living areas.
We look for staining and mould growth around penetrations, ceiling corners and roof space timbers where minor roof, flashing or gutter issues can create intermittent dampness—often missed until ceilings discolour.
Your report documents where mould is present or suspected, the most likely moisture source (leak, condensation or ventilation), and prioritised actions such as repairs to stop water entry, ventilation improvements, and when specialist mould remediation is warranted.

Find answers to the most frequently asked questions about our inspection service.
We commonly find mould in bathrooms with short or poorly ducted exhaust fans, laundries where dryers vent internally, and bedrooms where wardrobes sit on cooler external walls. In older Box Hill houses, subfloor dampness and limited ventilation can contribute to mildew smells indoors. We also see mould at window frames and corners where winter condensation repeatedly wets paint and plaster.
In many cases, yes. Leak-related mould often presents as localised staining and dampness around plumbing, shower recesses, balconies, roof penetrations, or gutters, and may worsen after rain or use. Condensation mould is usually more widespread on cold surfaces like windows, external wall corners, and behind furniture, and is linked to poor airflow and high indoor humidity. We document the likely driver and what to investigate next.
A mould presence inspection focuses on identifying visible growth, moisture indicators and mould-risk conditions, then explaining likely causes and next steps. If sampling is needed (for example, where the type of contamination must be confirmed or there are health concerns), we can discuss suitable options and whether an environmental hygienist or laboratory testing is appropriate. The aim is to avoid unnecessary testing and focus on fixing the moisture source.
Renovations can cover evidence without removing the cause. Fresh paint may conceal staining, and new cabinetry can block airflow behind vanities or in laundries. Sealed windows and added insulation can also increase condensation if ventilation isn’t improved. In some homes, extensions change drainage or subfloor ventilation and create new damp zones. We look for signs that moisture is still active, not just cosmetic improvements.
Start by stopping the moisture source. That may mean repairing leaks, improving bathroom/laundry exhaust, venting dryers externally, or increasing underfloor airflow. Cleaning without addressing moisture usually leads to regrowth. We’ll outline practical actions based on where mould is present and how it’s forming, and advise when professional remediation is sensible—particularly if mould is widespread, persistent, or appears to be inside building materials.
