Croydon South homes often deal with cooler mornings, shaded blocks, and older wet areas where moisture lingers—ideal conditions for mould growth behind walls, in ceilings, and around bathrooms and laundries.

Our comprehensive service includes everything you need to make an informed decision about your property.
We inspect shower recess corners, grout and silicone junctions, vanity kickboards, toilet bases, and laundry cabinetry for mould growth, swelling, and moisture staining. These zones often hide slow leaks and recurring dampness that reappears after cleaning.
We assess ceilings for peeling paint, spotting, and mould halos around bathroom and kitchen exhaust points. In Croydon South homes with older fans or poorly ducted systems, moist air can dump into the roof space and show up as ceiling mould over time.
We check external corners, behind furniture, wardrobe backs, and window reveals for mould indicators linked to condensation. This is common in cooler rooms or where airflow is reduced by heavy curtains, packed storage, or older window seals.
We inspect beneath kitchen, bathroom, and laundry sinks and around dishwashers for hidden dampness and mould odour. Small plumbing drips can soak cabinetry and flooring long before there’s obvious surface mould.
Where safe access is available, we look for roof leaks, damp insulation, and mould on timbers or plaster backs that can drive mould inside living areas. Even minor roof plumbing issues can cause repeated mould patches on ceilings.
Your report separates likely moisture sources (leaks, ventilation, condensation) from visible mould locations, with annotated photos and prioritised recommendations. This helps you brief a plumber, roofer, or mould remediator with clear, site-specific information.

Yes. In Croydon South, mould often shows up where older waterproofing, deteriorated silicone, or repeated regrouting has masked a slow moisture issue. Renovated laundries and bathrooms can also create new junctions between old plaster, new tiles, and cabinetry where moisture gets trapped. An inspection helps pinpoint whether it’s a leak, poor exhaust performance, or condensation so the fix targets the cause.
Leak-related mould is usually localised near plumbing, showers, roofs, or external wall entry points and may be paired with staining, swelling, or persistent damp materials. Condensation mould tends to appear on colder surfaces like external corners, window reveals, and behind furniture, often in winter or in poorly ventilated rooms. We look at patterns, locations, and contributing building factors to determine the most likely driver.
A mould presence inspection primarily focuses on identifying visible mould and the building conditions that support it, supported by moisture-related observations and photo documentation. Air or surface sampling can be useful in some situations, but it’s not always necessary and can be misleading if the moisture source isn’t addressed. If sampling would add value for your Croydon South property, we’ll explain why and what it can and can’t confirm.
Pay close attention to bathrooms and laundries (especially around shower bases and vanities), built-in robes on external walls, ceiling corners in south-facing rooms, and any converted garage or extension where insulation and ventilation may differ from the main house. Also check for musty odours in bedrooms after the home has been closed up. An inspection documents these risk zones and highlights likely moisture contributors.
It can, if the moisture issue remains. Cleaning may remove surface growth, but mould returns when humidity, condensation, or damp building materials persist. Recurrence is common in areas with weak exhaust ventilation, ongoing shower leaks, or cold external corners that attract condensation. Our inspection focuses on identifying why the area stays damp, so remediation and repairs have a better chance of being permanent.
