Often window leaks are not apparent, however their presence can cause serious issues in your home if left unattended. Leaky windows can lead to mold development in walls or around windows, and they can reduce the air quality in your home by allowing allergens to seep in from the outdoors. In addition window leaks can significantly reduce the energy efficiency of your home, causing your heating and cooling systems to work extra hard, using unnecessary energy to keep the temperature of your home comfortable. To help reduce, prevent or eliminate these serious home problems, it is necessary that you keep an eye out for common signs that your windows are leaking and are in need of repair. Here are some of the most common warning signs that the windows in your home are leaking.
Moisture around the window itself is a sure sign of a window leak. When there is a crack or opening in your window, often condensation will form in the panes, causing them to look foggy, or moisture will seep into your home, becoming apparent over time. This may even impact the wall area around the perimeter of the window, which could lead to mold. It could also deteriorate your walls and cause paint to sag or wear down with wetness. You will also see that moisture begins to build up when it rains since rainwater is seeping in through these cracks and leaks, which could even damage the floors of your home.
Another way to tell if your windows are leaking is if they shake. Manually, try to shake and rattle the window back and forth gently. A well-installed window should be set into the wall securely so that it doesn’t budge. The window itself should be flush to the wall on all four sides. If, when you rattle the window, it begins to shake or it feels loose, your window is likely leaking. You may even need to have a professional come in to re-install the window fixture properly to avoid future problems or to prevent the issue from worsening over time and with use.
If you see chipped or cracked caulking, you may also have a leak. Over time, caulking will begin to wear. When it does, it begins to peel away, leaving cracks or other gaps exposed. It is wise to regularly re-caulk your windows to prevent this from happening. If you do see that caulk is peeling, you should remove it completely and clean the area thoroughly. Then, you can re-caulk the area, sealing off any leaks or cracks around the edges of your window.
All of these signs will help you to identify a window leak issue and prevent any serious home issues from arising as a result. Leaks are common, but that doesn’t mean they aren’t harmful. Leaks can contaminate the air in your home, make it difficult to achieve an optimal home humidity level or temperature, and they can also lead to mold. Finding and correcting the source of a leak by observing these warning signs can help you to identify the problem and repair it properly.
