Your windows are an extremely important part of both your home's interior and exterior design. They are also subjected to a significant amount of wear because of excessive exposure to the elements, causing them to break down. Worn down windows can pose a number of problems to your home, such as moisture accumulation and insulation problems. There are a number of things that you can look out for to determine when it's time to have your home's windows replaced.
Perhaps the most notable warning sign that your window needs to be replaced is if there is any sign of physical damage or stress to the glass itself. This isn't always noticeably large cracks. Glass that has been chipped, dented, or shifted out of place are all warning signs as well because the structural integrity of the pane of glass has been reduced, increasing the chances that the entire window will shatter. Not only does this pose a safety hazard, but broken windows can allow the elements and pests into your home if not dealt with immediately.
In the same vein as the above point, damage to the window frame can allow moisture to enter your home. Moisture can result in mold growth, which can be a serious health hazard. However, cracks and broken frames are not the only form of damage to look out for: wood frames can warp, vinyl frames can become brittle and crack, and aluminum frames can be easily dented out of shape, all of which will open up gaps between the frame and the interior of your home.
Higher Energy Bills
As a result of damage to the glass or the frame, visible or not, heat exchange can occur between your home and the outside. Sometimes damage to your windows can't always be seen – if you notice that your energy bills are rising without changing your appliance usage, your windows may not be insulating your home well anymore, increasing the load on your air conditioner and heating systems.
Similar to the above point, if you notice that you're experiencing higher noise levels than normal within your home, your windows may be losing their insulative qualities. If sound can more easily penetrate your home, so can the exterior temperature and moisture, which can be expensive problems to have. You should contact a contractor (such as one from Expert Windows and Insulation) to inspect your windows and see what sort of condition they're in.
