Our comprehensive service includes everything you need to make an informed decision about your property.
We closely inspect showers, vanities, baths, laundries and adjacent skirtings for signs of active moisture, failed sealants and water escape points that commonly lead to mould blooms and wall cavity dampness.
For Richmond terraces and cottages, we assess accessible subfloor areas for damp soil, poor ventilation, pooling water and mould growth on bearers/joists, because persistent underfloor moisture can drive musty odours and mould at floor level.
We assess the interface between original brickwork and newer additions, including flashings and roof-to-wall junctions, where movement and detailing issues can allow water ingress and create concealed mould conditions behind linings.
We check window frames, sills and surrounding plaster for condensation patterns, peeling paint and black spotting—common in bedrooms and living areas where airflow is limited or glazing is upgraded without matching ventilation.
We look for staining, mould spotting and humidity damage around ceilings, cornices and light fittings, and note roof leak indicators that can seed mould in insulation and ceiling voids.
Your report documents mould-affected areas with photos and links them to likely moisture drivers such as leaks, waterproofing breakdowns, rising damp symptoms or ventilation shortfalls, so rectification can be properly scoped.

Many Richmond homes are older and have been renovated to improve comfort, which can reduce natural draughts. If ventilation hasn’t been upgraded at the same time, humidity from showers, cooking and drying clothes can linger. Ground-level rooms and subfloors in older terraces can also stay damp after rain if drainage is poor or airflow is restricted. These conditions allow mould to establish and keep returning.
Yes. The goal isn’t just to note mould spots; it’s to identify what’s feeding them. We assess common moisture drivers such as bathroom waterproofing breakdown, plumbing leaks, roof or flashing issues, condensation patterns and subfloor dampness where access allows. The report explains the likely causes and what type of trade is typically needed to confirm and fix the source so you’re not only treating the symptoms.
Where it’s safe and accessible, we inspect inside bathroom and kitchen cabinets, under sinks, around dishwasher connections, and behind items that can be moved without risk of damage. These are common hidden mould zones because small leaks can go unnoticed. If access is restricted (for example, fixed panels or fully packed wardrobes), we’ll note limitations and recommend practical follow-up checks or invasive investigation if the risk appears high.
In Richmond apartments, mould often tracks back to balcony waterproofing, window/door seals, bathroom exhaust performance and condensation on colder external walls. Warehouse-style conversions can have high ceilings and hard surfaces that cool quickly, leading to condensation if heating is intermittent and ventilation is limited. We focus on wet areas, external wall junctions, window lines and any signs of water entry from balconies or façade elements.
First, address the moisture source—cleaning alone won’t stop mould returning. Depending on the findings, the next step may be a plumber for leak testing, a waterproofer for shower or balcony membranes, or a builder to correct ventilation and building defects. For significant contamination, engage a qualified mould remediation professional. Our report helps you prioritise actions and discuss scope and costs before settlement.
