Damp & Mould Survey
Excess moisture within the fabric of a building leads to insulation inefficiencies, heat loss, and an increased chance of damp and mould.
Ensuring a building has adequate and effective moisture protection is vital in managing heat loss, however due to the nature of water ingress it can sometimes be a complex and challenging task. At iRed we use the latest thermal imaging technology to accurately detect fluctuations in thermal insulation caused by water ingress, enabling our team to precisely measure the point of inadequacy or failure. This non-destructive analysis of the whole building envelope allows us to quantify heat loss and therefore indicate areas of risk.
Providing expert analysis is especially important within a damp and mould survey as small variations in data measurement can exponentially magnify the margin of error. This is because buildings are in a constant state of flux influenced by changeable environmental conditions both internally and externally. As a consequence of this, a singular measurement may not always be representative of the overall situation. However, combining different analysis methodologies can produce very useful results. This is why our reports will incorporate the use of a Thermal Index (TI) to demonstrate areas of the building fabric that are likely to be affected by condensation and mould.
Frequently Asked Questions
Thermography (otherwise known as “Thermal Imaging”) is a specialist technique which uses infrared-sensitive cameras to inspect buildings, electrical equipment, rotating machinery and devices to detect faults or problematic areas, as part of routine maintenance or fault-finding. This non-invasive method allows the identification – both in terms of location and severity – of problems associated with heat loss.
Rather than using a CMOS or CCD detector which records different levels of a range of visible light colours, a thermal imaging camera uses a microbolometer array to accurately measure levels of infrared radiation across a scene. This temperature data is then processed to produce a thermal image (known as “thermogram”), which can then be very precisely quantified or measured.
It is recommended that certain conditions are met to ensure any outcomes within our reports are fully accurate and actionable. To ‘see’ heat loss (or gain) at least a 10°C temperature difference between the inside and outside must be achieved for a minimum of 24 hours prior to the survey if occupied, or 72 hours for a ‘dead’ building. If the building has no operational heating system, temporary direct heaters (such as space heaters) may be required. It’s because of this that surveys can often take place very early in the morning or late in the evening.

Upon completetion of a thermographic survey, clients will recieve a precise and detailed report featuring comments and advice from experienced and highly qualified thermographers. We only allow level 2 or above thermographers to produce our reports, ensuring your report is as comprehensive as possible. We’re then available to help, explain and troubleshoot your new thermal data with you as much as you need.
Absolutely! All of our thermographers are level 1/2/3 certified. We are also a CHAS accredited contractor, registered Constructionline supplier, UKTA approved to conduct BREEAM thermographic surveys, BINDT approved training centre and ISO 9001:2008 registered.

No, it’s totally harmless! Everything gives off infrared radiation, and thermal imaging cameras merely detect this existing radiation (rather than emit anything).
