When you’re cuddled up at home, on the couch or in bed, the last thing you want to feel is a waft of cold or hot air coming in from a crack in a window or door. Air leaks in windows and doors can be annoying as well as cost you money from air conditioning or heat escaping during the summer and winter months. There are a few ways that you can figure out where these air leaks are so that you can get the appropriate repairs made. So, how do you spot an air leak? Here are three ways that you can check your windows and doors, and other areas of your home, to see if you have an air leak.


Do a Visual Inspection

Go through your whole house and look for any visible openings, cracks, and failed caulking materials. If you can physically see these problems, then they are most likely the cause of your drafts and what is contributing to the energy costs that are steadily rising. Other than the windows and doors, which are the best place to start, you should also check any corners, outdoor faucets, and chimneys or sliding doors. Other less likely causes of air leakage can be electrical outlets, gas entrances, cable phone lines, and vents and fans. When you do this, feel around, see if there are spots that are colder or warmer (depending on the time of year) to see if certain areas are more likely to be the culprit.

The Smoke Method

You will need a lighter and a candle or incense stick to conduct a smoke test to try to find air leaks. To do this test, close every window and door and make sure that no fans are running. Light the candle or incense stick and move it around window and door frames, keeping the flame or smoke as vertical as possible. Observe to see if the smoke or flame are blown inward into your home or sucked outward anywhere along the frame. If this occurs, then it means that you have an air leak in that spot on your door or window. If you do have some air leaking, try to clean the area to see if dirt or debris was blocking the window or door from sealing properly. Otherwise, it is time to call a professional to fix the issue.

Use an Air Leak Detector

An air leak detector also called an infrared thermometer measures the air temperature around your windows and doors. Using an air leak detector, you can find exactly where the temperature around your windows and doors is cooler, which allows you to pinpoint leaks. Once you know where the leaks are, you can communicate with a technician to get them fixed a lot easier.
