Thermal inspection uses still and infrared video cameras to measure the temperature of surfaces. These instruments detect light in the thermal spectrum.
The temperature differences in the building's skin are captured as images on the video or film, which change from white in warm sections to black in colder ones.
The auditor can assess if insulation is necessary based on the obtained photographs.
In order to guarantee that insulation has been put correctly, they also function as a quality control tool.
In this article, we are going to mention the most important items in the thermal inspection checklist and also the importance of thermal imaging house inspection.
Benefits of Thermal Imaging in Home Inspection
The advantages of utilizing thermal imaging during a house inspection are broken down as follows:
1. Unnoticed Moisture Problems
Thermal imaging is particularly good at finding hidden moisture issues, such as leaks in roofs, behind windows, or behind walls.
Early identification of moisture entry minimizes mold formation, which may be expensive to fix and provide health problems.
2. Potential Flaws in the Structure
Uneven heat patterns can occasionally point to structural problems, such as insulation gaps or fractures, enabling more research and possible repairs to be made before the problems get worse.
3. Electrical Faults
By finding regions with unusual heat signatures, thermal imaging can occasionally discover possible electrical issues, such as overloaded circuits or weak connections. By doing this, you can protect the inhabitants' safety and help avoid electrical fires.

A key to increasing energy efficiency is locating leaks in the building envelope. Problems such as air leaks around windows, doors, and attic access points can be found via thermal imaging. Other problems include:
- Wall, ceiling, and attic insulation that is either missing or insufficient.
- Systems that distribute heat and coolness unevenly and are inefficient.
- Resolving these problems can result in more pleasant living quarters and lower utility costs.
Possible imperfections in structure:
Uneven heat patterns can occasionally point to structural problems, however they are not always conclusive. Examples include:
- Foundation or wall cracks
- Flaws in the construction materials
- Uneven foundation settlement
Thermal Inspection Checklist
Key places where thermal imaging might show possible issues should be included in a thorough thermal inspection checklist for a house assessment.
Below is a summary of the key elements:
- External Walls: Examine the areas surrounding windows, doors, siding penetrations, and foundation walls for any air leaks.
- Roof: Keep an eye out for indications of moisture seepage near vents, skylights, and roof flashing.
- In the attic, locate any locations that have insufficient insulation, air leaks around access hatches, and possible moisture issues close to soffits.
- If appropriate, look for signs of moisture penetration around foundation walls, foundation cracks, and possible cold air leaks in the basement or crawlspace.
- Walls: Pay particular attention to areas around laundry rooms, kitchens, and bathrooms for any possible moisture problems.
- Ceilings: Look for any air leaks at attic access hatches, recessed lighting fixtures, and ceiling penetrations for electrical or plumbing lines.
- Floors: Although it has limits, thermal imaging can occasionally be used to find possible moisture issues in subfloors (particularly in basements or crawlspaces) and detect radiant heating systems, if they are present.
- Accessible Plumbing Lines: Check exposed radiant heating systems and hot water pipes for leaks or obstructions (however the effectiveness of these measures varies depending on the material and water temperature).
- Electrical Panels (With Caution): A trained inspector may occasionally utilize thermal imaging to detect possible overheating of electrical panels or overloaded circuits (restricted due to panel enclosure), although caution is advised owing to safety considerations.
Key Considerations for IR Thermography Inspection
When doing infrared thermography (IRT) examinations for a variety of applications, bear the following points in mind:
