We use state-of-the-art infrared (IR) cameras to find problems that aren’t always apparent to the naked eye. An IR camera translates the heat signatures of objects into colours on a gradient scale, with higher temperatures appearing as lighter colours, and lower temperatures and wet areas appearing as darker colours. By evaluating these images, we can detect sources of energy loss, locate areas of moisture intrusion, pinpoint dangerous hot spots in the electrical system, and uncover other problems, such as wood-destroying pest and rodent infestations, as well as flue leaks in the chimney, which can lead to carbon monoxide poisoning.
