When you hear the expression hot joints, your first though might not be electrical issues, but it can be a serious problem. Hot joints happen when there is a faulty electrical connection. It could be that something isn’t connected well or that there is a malfunction in an appliance, but what will happen is that the joint heats up to the point where it can pose a serious fire hazard. You might be able to smell this when it happens if there is some materials nearby that are affected by this heat, but other than that it can be very difficult to detect.
This is where thermal imaging comes in handy. It helps greatly in identifying electrical issues like hot joints since it will stand out on a scan.
Thermal imaging scans as part of a home inspection can save you a lot of money and headaches by finding issues that aren’t clearly visible to the naked eye.
