Ashburton homes often combine older brick veneers, renovated wet areas and shaded gardens—conditions that can trap moisture in bathrooms, laundries and subfloors where mould can spread unnoticed.

Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect bathrooms, ensuites and laundries for visible mould, musty odours and moisture staining around showers, baths, vanities and splash zones. These are the most common mould sources in Ashburton renovations, where waterproofing, grout failure or poor exhaust fan performance can allow damp to linger.
We check for elevated moisture in plaster, skirting areas and ceilings near wet rooms and roof penetrations. This helps identify whether mould is likely being driven by active leaks, intermittent water ingress, or chronic condensation—so you’re not treating symptoms while the cause remains.
Many Ashburton houses have subfloor spaces that can hold humid air if vents are blocked or the ground is damp. We look for fungal growth on timbers, damp soil, poor ventilation paths and plumbing drips that can contribute to mould odours and deterioration of bearers, joists and flooring.
We pay attention to wardrobes on external walls, south-facing rooms and corners behind furniture where airflow is restricted. We look for mould spotting, bubbling paint and damp-feel surfaces that often point to condensation rather than a plumbing leak—common in well-sealed homes with limited ventilation.
We inspect around windows and sills for staining, swollen trim, peeling paint and mould growth that can follow failed seals or poor drainage. In Ashburton’s mix of older and updated windows, small seal defects can quietly feed mould on adjacent plaster and inside window reveals.
Your report documents affected areas, likely moisture sources and clear next steps such as ventilation improvements, targeted repairs, or further investigation by a qualified mould remediation provider if required. This supports confident decision-making for buyers, sellers and owners planning works.

Yes. Many Ashburton properties have suspended timber floors with subfloor voids that rely on good cross-ventilation. If vents are blocked by landscaping, paving or stored items, humid air can build up and encourage fungal growth on timbers and the underside of flooring. We check accessible subfloor areas for dampness, ventilation shortfalls and signs of mould so you can address the cause, not just the smell.
We look at the mould pattern, nearby plumbing and roof elements, and whether moisture readings are localised or spread across cooler surfaces. Condensation mould is often found on external walls, in corners and behind furniture where airflow is poor, while leaks tend to create more concentrated staining and dampness near a water source. The report explains the most likely driver and practical next steps.
A mould presence inspection is usually the first step because it identifies where mould is likely present and why it’s occurring. If you need species identification, air sampling, or confirmation for health or tenancy documentation, specialist mould testing may be appropriate. We’ll note when further testing could be helpful, but most owners get strong value from locating moisture sources and fixing the conditions that allow mould to grow.
Common hidden locations include behind bathroom vanities, around shower recess edges, inside built-in wardrobes on external walls, and in laundries where washing machines or trough plumbing has slow leaks. In some Ashburton homes, mould also shows up around older window frames and inside subfloors where ventilation is limited. We target these zones during the inspection and photograph any evidence found.
Yes. We document affected areas, likely moisture contributors and the practical sequence of actions to reduce recurrence. That may include repairing a leak, improving bathroom exhaust performance, clearing subfloor vents, addressing drainage against walls, or engaging a qualified remediation provider for safe removal where growth is extensive. The goal is clear decision-making, whether you’re buying, selling or maintaining your Ashburton property.
