Princes Hill’s older terraces and period homes often hide moisture in subfloors, chimney breasts and poorly ventilated wet areas—conditions that can drive mould even when a home looks freshly renovated.

Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect bathrooms, laundries and kitchens for visible mould, moisture staining, failed seals and inadequate exhaust. In Princes Hill renovations, fans are sometimes undersized or not ducted effectively, which keeps humidity in the room and drives mould on ceilings, cornices and grout lines.
We check for condensation patterns and damp-prone cold spots, including bedrooms with wardrobes on external walls. Older glazing and shaded elevations can create recurring condensation that looks like a “cleaning issue” but is actually a ventilation and thermal imbalance problem.
For homes with suspended timber floors, we look for blocked vents, poor airflow pathways, damp soil, and signs of fungal activity beneath the floor. These conditions can contribute to musty odours and mould inside the home, and can affect floor framing if left unchecked.
We check accessible roof void areas for water entry, damp insulation, mould-like growth on timbers, and bathroom exhaust termination issues. In older homes, minor roof leaks or exhausts venting into the roof space can quietly sustain mould for years.
We assess the outside conditions that commonly feed indoor mould—overflowing gutters, downpipe discharge points, ponding near walls, and garden beds built up against brickwork. Even small, recurring wetting can keep internal wall bases damp.
We document where mould is present (or where conditions strongly suggest hidden growth) and link it to the most plausible moisture source—leaks, condensation, rising damp symptoms, or poor ventilation. This helps you prioritise fixes rather than treating surfaces repeatedly.

Many Princes Hill homes have original construction details that don’t manage modern moisture loads well, such as limited subfloor ventilation and older wall systems that dry slowly. Renovations can add sealed-up rooms, ensuite bathrooms or new laundries without matching ventilation. If exhaust fans are weak, not ducted correctly, or windows stay closed due to traffic noise, humidity builds and mould returns.
Yes, we look at location, patterns and supporting moisture signs. Condensation-related mould commonly appears on ceilings, window reveals, and cold external corners, often worsening in cooler months. Leak-related mould is more localised and linked to plumbing, showers, roofing or gutters, with staining, bubbling paint or persistent damp patches. We document clues that point to the most likely driver and the next checks needed.
We focus on areas where mould can thrive out of sight: behind and under sinks, around showers and baths, inside built-in wardrobes on external walls, and along skirtings where dampness can wick up. Where access is available, we also check subfloor and roof void spaces for moisture conditions and mould-like growth. If access is restricted, we note limitations and risk indicators.
They can be. Rear additions may have less natural light and reduced cross-ventilation, particularly where side access is tight or courtyards are enclosed. Converted laundries and added bathrooms sometimes rely on a single exhaust fan and sealed windows, which isn’t enough to purge steam and drying moisture. We pay close attention to extraction, sealing, drainage and any signs of chronic dampness around these newer zones.
Yes. Our report outlines the likely moisture sources and the practical next steps, such as improving mechanical ventilation, repairing leaks, correcting external drainage, or engaging qualified mould remediation where contamination is significant. We also flag conditions that can keep feeding mould—like blocked subfloor vents or exhausts venting into roof spaces—so fixes address the cause, not just the visible growth.
