Our comprehensive service includes everything you need to make an informed decision about your property.
We check bathrooms, ensuites, laundries and toilets for visible mould, damp junctions and the tell-tale staining that suggests ongoing humidity. We also assess whether exhaust fans appear appropriately ducted and vented, because poor extraction can feed mould on ceilings, grout lines and behind vanities.
We use moisture detection to identify elevated readings around showers, baths, laundry troughs, external wall corners and window reveals. This helps distinguish a one-off condensation issue from a persistent moisture source that can keep mould returning even after cleaning.
Where accessible, we assess subfloor conditions such as ventilation, damp soil, standing water, and mould on bearers/joists or the underside of flooring. Donvale’s sloping blocks can concentrate runoff under the house, so subfloor conditions can be a primary driver of indoor odours and mould.
We look for mould staining, damp insulation, water marks and signs of roof leaks or condensation in the roof space where accessible. Ceiling cavity moisture can migrate to cornices and plasterboard and may indicate flashing issues or inadequate ventilation.
We check for mould around window frames, sills and blinds, plus behind furniture and inside built-in robes on external walls. These areas commonly show mould first due to cold surfaces and restricted airflow, especially in shaded rooms.
Your report records where mould is present, likely moisture sources (leaks, rising damp indicators, condensation patterns, drainage overflow), and recommended actions. We outline which issues are maintenance-related versus those that may warrant further investigation by a plumber, roofer or waterproofing specialist.

Find answers to the most frequently asked questions about our inspection service.
In Donvale, mould commonly appears where moisture lingers: bathrooms with older ventilation, laundries, and built-in robes on external walls. Homes on sloping blocks can also have damp subfloors if drainage and downpipe discharge aren’t managed well. During an inspection, we look for visible growth plus moisture patterns that suggest condensation, leaks or poor airflow.
Often, yes. We compare where mould is present with moisture readings and building clues such as staining, swelling to skirting boards, shower junction deterioration, and roof-space water marks. Condensation-related mould is usually widespread on cold surfaces and corners, while leaks tend to create localised high moisture and damage. If it’s unclear, we’ll note what further checks are sensible.
A mould presence inspection is typically focused on identifying visible mould, moisture drivers and risk areas, rather than laboratory identification. In many cases, you don’t need a lab result to fix the problem because the key is stopping the moisture source. If sampling may help due to health concerns or disputed causes, we can advise on appropriate next steps.
More shade and less sun exposure can slow drying on external walls, around windows and in under-house areas, which increases the time surfaces stay damp after rain. If ventilation is limited, that dampness can translate into indoor humidity and mould growth in corners, wardrobes and behind furniture. We pay close attention to ventilation paths and moisture entry points typical of shaded sites.
First, confirm whether the mould is linked to an active moisture problem or a ventilation/maintenance issue. Use the report to ask the vendor about past leaks, bathroom waterproofing, roof repairs and drainage works, and consider getting quotes for rectification. If moisture readings suggest ongoing dampness, you may need specialist follow-up (plumber, roofer or waterproofing) before committing.
