- You Can Feel, See, and Hear the Air. The first thing you need to look for when you’re trying to spot a drafty window is the air that you can feel. Try turning off the TV, radio, and other sources of noise, then walk around your house to see if there are any rattling sounds that you can hear. Another great way to see if there’s any air that’s coming through the window is by looking at the drapes and curtains. If you can see movements that aren’t caused by the fan or AC, it may be a cause for concern.
- You Find it Difficult to Open and Close the Windows. If you find an opening and closing a window to be incredibly difficult, it may be a sign that the window is warped or bloated. This typically happens to wooden window frames, as wood is highly susceptible to heat and water. These things often alter their shape and size over a long period of time. When windows warp, it may break the air seal, allowing a draft to come through.
- Your Windows Get Fogged Up During the Summer and Winter. Condensation isn’t always caused by faulty windows, as there are hundreds of reasons how moisture condensation on glass surfaces can occur. It’s normal to see your windows fog up when you cook, do laundry, or take a hot shower. However, when none of these things is happening and you see your windows fogging up, it may be a sign that your window isn’t in the best condition. When warm air comes into contact with cold temperature, condensation will start to occur. During the summer or winter, the difference in temperature between the interior and exterior of your home is much more drastic, so if you see a window fogging up during these months, it’s time you have it fixed.
