What does mould in a property actually look like?

Mould is a common issue in many properties, and identifying it early is crucial for maintaining a healthy living environment. Visually, mould can manifest in various forms and colours, often depending on the type and location of growth.

Appearance and Colours

Mould often appears as discoloured spots or patches on surfaces. Common colours include black, green, brown, and white. For instance, Stachybotrys chartarum, commonly known as toxic black mould, presents as dark greenish-black patches with a wet, shiny, or slimy appearance. In contrast, other moulds may have a dry, more velvety texture.

Common Locations

Mould thrives in damp, humid environments. It is frequently found in areas such as bathrooms, kitchens, basements, and around windows where condensation accumulates. Additionally, mould can grow on various materials, including walls, ceilings, wood, and fabric. Recognising these hotspots can aid in early detection and prevention.

Identifying Mould vs. Condensation Marks

It's essential to distinguish between mould and simple condensation marks. Condensation typically appears as water droplets or a film of moisture on surfaces like windows or cold walls. In contrast, mould manifests as spots that can be fuzzy or slimy, often in shades of black, grey, brown, or green.

Tools for Detection

For homeowners seeking to identify mould, several products are available:

1. Mould Test Kits: These kits allow users to collect samples from suspected areas and send them to laboratories for analysis. For example, the Evviva Sciences Mold Test Kit provides ten simple detection tests suitable for various surfaces.

2. Moisture Meters: Devices like the Brennenstuhl Moisture Detector help detect moisture levels in materials, indicating potential mould-prone areas.

"Mould can appear 'fuzzy' and look like a stain, smudge or discolouration."

In closing, being vigilant about the appearance and common locations of mould can help in its early detection and remediation. Utilising available detection tools can further assist homeowners in maintaining a mould-free environment.
