Home Inspections have been, traditionally, visual inspections. This has been taken to mean visual to the human eye and readily seen. But, just as home construction has become more technical, so has the practice of professional Home Inspection. Electrical Circuit Analyzers, gas and CO meters and UV flashlights are now commonly used for home inspections. The newest such tool is the Thermal or IR imaging camera.
Home Inspection Carolina inspectors now perform infrared home inspections. All objects have a surface temperature caused by emissivity. As the temperature changes all the material including drywall, wood, and sheathing material all change temperatures at different rates. Our Charlotte home inspectors use infrared cameras to see these settle variation in temperature. When there is moisture intrusion or missing insulation it shows as cold spots. When wiring or breakers are overheating they show up as hot spots. When our inspector scans they look for anomalies in patterns. Within these anomalies there are usually problems. If you want one of the most thorough inspections with the use of infrared scans call Home Inspection Carolina Today!
Infrared Thermal Imaging
Infrared imaging provides important information relating to otherwise inaccessible areas of a residential building. Infrared detects extremely small but crucial differences in temperature from one area of a house to another. These temperature variations show up on the camera’s view screen as “cold” or “hot” spots, which reveal hidden problems that often cannot be detected in the course of a traditional visual inspection. These problems may include:
- Faulty wiring, breakers and fuses
- Hidden moisture intrusion
- The moisture sources of mold
- Pipe and duct work leaks
- Roof and ceiling leaks
- Foundation cracks
- Heat/energy loss
- Structural concerns
- Missing insulation
- Ventilation problems
- Moisture associated with termite nests
- Rats, mice and other pests
Why Perform Infrared Home Inspections?
Combined with traditional home inspection techniques, the infrared inspection method reveals substantially more of the house than can be perceived by the naked eye and conventional inspection tools. Many things can’t be seen with only a flashlight.
Examples of infrared inspection applications: § Water intrusion: scanning interior surfaces of a building with an infrared camera can reveal excess moisture due to plumbing leaks, roof leaks, leaks around windows, etc. Wet areas of building materials cool when energy is transferred during the water evaporation process; therefore, a wet (“cooler”) area will stand out from the surrounding dry (“warmer”) surface.
Insulation deficiencies: appreciable temperature differences, due to variations in thermal energy (heat) transfer, allow for detection of deficient or missing insulation when scanning ceiling and wall surfaces.
Roofing leaks: scanning roof coverings can reveal water intrusion and accumulated moisture below the surface. Due to its thermal properties (high thermal capacity), water typically gives up heat at a much slower rate than the surrounding roof materials. The areas of accumulated moisture can therefore be detected when scanning the roof surface. This type of roof inspection is best done in the evening or early nighttime after thermal energy imparted during the daytime is transferred or released.
Electrical systems: deficiencies within the electrical system can be made visually apparent by use of an infrared camera. For example, a deficient connection between electrical components can result in resistance which will manifest in an apparent temperature elevation when compared with similar types of connections under similar load conditions.
Structural issues: differences in thermal capacity, conductivity, and other intrinsic qualities of building structural components can allow for their detection when scanning walls, floors, and ceilings with an infrared camera. Under the right conditions, missing structural components, and portions of structural components which are damaged (to the extent that their intrinsic qualities are significantly changed), can be detected.
*Although infrared thermal imaging is a far better diagnostic tool than the naked eye, it does not guarantee 100% accuracy, unless removal or destruction of components can be achieved to validate findings. When possible, other tools are used to verify thermal images, but even with these considerations we do not claim to have x-ray vision. Conditions may change and cause the apparent temperatures revealed on thermal images to be different at any given time.
