Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect around showers, baths, vanities, splashbacks, under-sink cabinets and washing machine taps for mould staining, musty odours and moisture damage. These are common Boronia trouble spots where small leaks and poor exhaust ventilation keep humidity high and allow mould to colonise silicone lines, plasterboard edges and cabinetry.
Where there is access, we check subfloor zones for damp soil, poor cross-ventilation, fungal growth on bearers/joists and signs of long-term moisture. In homes with low clearance or blocked vents, mould can build unnoticed and migrate into living areas through gaps in floorboards and service penetrations.
We look for mould growth on rafters, sarking and insulation, and assess likely contributors such as bathroom exhausts venting into the roof void, inadequate roof ventilation, or ducting issues. Roof-space mould is often missed during walkthroughs but can indicate ongoing condensation problems that worsen in cooler months.
We check external walls, corners, behind furniture where accessible, window reveals and built-in robes for condensation patterns and mould spotting. This helps distinguish between lifestyle condensation issues and building-related moisture entry, which changes the remedy and the urgency for repairs.
We examine areas around windows, door frames, skirtings and ceiling junctions for bubbling paint, staining, swollen trim and other indicators of moisture movement. These clues can reveal water ingress points or persistent condensation zones that keep feeding mould even after superficial cleaning.
Your report documents mould-affected areas and moisture indicators with photos, clear descriptions and practical next steps. Where appropriate, we outline likely causes to investigate (leaks, ventilation shortfalls, drainage/ground levels, or roof-space exhaust issues) so you can brief a plumber, builder or remediation team accurately.

In Boronia we often see mould linked to damp subfloors on shaded blocks, older bathrooms without effective exhaust fans, and roof-space condensation where ducting isn’t vented outside. Built-up garden beds and poor drainage can keep lower walls damp, while cold external walls and limited airflow can create condensation in bedrooms and robes. An inspection helps clarify which driver is most likely.
We look at the pattern and location of staining, moisture damage and the building context. Localised mould around plumbing points, swollen cabinetry or staining below pipework can indicate a leak. Widespread mould on cold corners, window reveals and external walls can suggest condensation and ventilation issues. We document evidence and recommend the most sensible next investigations to confirm the source.
Where safe access is available, yes. Roof spaces are important because bathroom or laundry exhausts that terminate in the roof void can drive mould on timbers and insulation. Subfloors matter where ventilation is restricted or ground moisture is high. If access is limited, we note constraints and focus on internal indicators that may still point to hidden mould or moisture conditions.
Pay close attention to musty odours, mould in built-in robes on external walls, and dampness signs near skirtings, especially where gardens sit high against the wall. Older wet areas can hide moisture behind tiles or around the shower base, and blocked subfloor vents can keep the underside of the home damp. A mould presence inspection helps map the risk areas before settlement.
We focus on inspection and reporting rather than performing remediation. If mould is identified, we explain the likely moisture drivers and the urgency based on location and extent. You can then engage the right trade—plumber, builder, ventilation specialist or mould remediation provider—with clear information. This approach helps avoid paying for cleaning without addressing the underlying moisture cause.
