What is a thermal imaging survey?
Thermal images work best when the house is heated and the outdoor temperature is low, ideally at least 10°C lower than indoors, so surveys are booked for cold mornings or evenings. We image the top-floor ceilings, the room-in-roof if you have one and the loft, and explain what each cold patch is likely to be. More about a thermal imaging survey.
