Mould & Moisture Assessment
The assessment is all about identifying the sources of moisture, humidity or condensation, measuring and recording the key elements that make up the environment, surface testing for ATP and then coming to a hypothesis on what could be happening before doing laboratory sampling.
The night before the assessment, we ask the occupants to keep all doors and windows closed up, from about 8pm onwards. This keeps mould growing indoors, to be ‘kept indoors’ as they typically release their mould spores in the evening and early morning. Therefore, there tends to be a concentration of mould spores and hyphae fragments in the air by doing this. Some mould spores won’t aerosolise so it comes down to the experience of the building biologist to determine potential areas of interest. Severely water damaged buildings will have extremely high levels of mould spores and hyphae fragments. A good indicator of this is the damp musty smells in a room, or if you start sneezing, coughing or have runny nose after walking into a room.
