Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect bathrooms, ensuites, laundries and kitchens for visible mould, swollen skirting, peeling coatings and damp odours. These rooms are common sources of persistent humidity, and small ventilation issues can spread mould into adjacent bedrooms and hallways.
Where accessible, we enter the roof space to look for mould on trusses, sarking, insulation and around penetrations (vents, flues, downlights). Roof condensation and small leaks can seed mould that later shows up as ceiling discolouration or a musty smell throughout the home.
For homes with subfloors or suspended floors, we check for damp soil, poor air movement, plumbing leaks and fungal growth on bearers/joists. In split-level Lysterfield homes, under-house zones can stay cool and humid, making them a frequent source of odours and mould spores.
We examine window reveals, sill edges, external corners, wardrobes and built-in cabinetry for condensation patterns and hidden mould indicators. These areas often trap cool air and moisture, particularly on shaded elevations and rooms that are kept closed up.
We check likely water entry pathways such as gutters, downpipes, overflow points, flashing details, cladding junctions and ground levels against the slab/brickwork. Poor drainage and splashback can keep walls wet and create mould internally, even when there’s no obvious indoor leak.
Your report documents suspect mould locations, supporting photos, and the likely moisture source driving each area (leak, condensation, rising damp influences or ventilation shortfalls). We also outline next steps so you can prioritise repairs, cleaning and humidity control in the right order.

Lysterfield has many leafy, shaded properties where walls and roofs dry more slowly after rain and overnight dew. Cooler winter temperatures can also create condensation on windows and ceiling surfaces, especially if bathrooms and laundries don’t exhaust well. Split-level and older brick homes may have subfloor zones that hold moisture, which can feed musty odours and mould growth indoors.
Leak-related mould is usually concentrated near a water source, such as a shower recess, pipe, roof penetration or failed flashing, and you may see localised staining or swollen materials. Condensation mould tends to appear in corners, on ceilings, behind furniture and inside wardrobes where air movement is poor. Our inspection looks for patterns and building clues that point to the most likely cause.
A mould presence inspection focuses on identifying suspect growth, moisture indicators and the building conditions causing it. If lab testing is required (for example, to confirm species or support a medical or tenancy dispute), we can discuss sampling options and the best locations to sample. In many property decisions, finding the moisture source and extent is the most valuable first step.
Yes. Larger lots often include sheds, studios or converted outbuildings that may have limited insulation, poor sealing and inconsistent heating. When these spaces are kept closed, humidity builds up and mould can form on wall linings, stored items and timbers. We can include these areas (where accessible) to help you understand whether moisture control, ventilation upgrades or building repairs are needed.
First, address the moisture driver—repair leaks, improve drainage, and ensure exhaust fans vent outside rather than into the roof space. Then plan remediation based on the extent: small surface areas may be cleaned with appropriate precautions, while larger or recurring growth may need professional remediation. Your report will outline practical priorities so you don’t waste money treating symptoms without fixing the cause.
