Fellow home inspector Richard and myself are looking for signs of water leaks with our thermal camera.

The image you see in the mirror with the colored background is actually our heat reflecting off the glass! Pretty cool isn’t it!? What I hope to find when searching for water leaks is that the water will be a different temperature than the walls. When it is and it’s active, the water looks dark blue (if it’s cooler) and shows up as a contrast in colors much as the mirror is doing. In some cases the water may move the insulation so I can see a temperature difference without the water leak being active.

Again, the camera is only a sample tool in trying to find moisture, it also takes experience, building knowledge, visual, tactile senses, maybe a moisture meter and some common sense to complete the job

The more I use my infrared camera, the more problems I find and the bigger the benefit for everyone concerned. I have discovered it is not a perfect tool, but it is a great aid in detecting some problems. I currently use it mainly for moisture intrusion problems. Typically any home I suspect has a water problem, I will take my camera out of the car and use it. Between my infrared camera, moisture meter, and experience of inspecting thousands of homes, I get a little more comfortable with it and so should the buyers.

The digital picture on the left (top) looks normal as you view underneath the window banks. The infrared picture on the right (bottom) shows dark stains inside the wall as a result of moisture getting into the wall cavity and rearranging the insulation. Since the insulation has been moved, it created a difference in temperature, which is what we actually see.

The other day I arrived at an inspection to find the water meter had been removed. Though this is nothing new lately, it is impossible to perform a full inspection without water. The selling Realtor thought the water was on (whoops)

So, I revisited a few days later after the new meter is installed. I turned it on at the street and there was plenty of water running inside. After 5 or so minutes I started loosing water pressure inside. I looked outside toward the water meter and saw water gurgling up through the ground.

Another good reason to make sure all utilities are on prior to the inspection.
