Old Windows – You haven’t replaced your windows in decades and have single pane windows. Window manufacturing technology has advanced greatly in recent times. Even if your windows are in pristine shape, the old technology could be costing you money. Many old windows were not developed to be energy efficient. Single pane windows are not as energy efficient as double or triple pane windows. If you want the compounding effect of lower energy bills, replace non energy efficient windows with newer energy efficient ones.
The Weather Outside is Inside – If you can easily feel the weather change or hear the whistle of wind inside your home through the windows, you do not have a tight seal. This is a definite sign that you need to replace your windows.
Noise – Just like the whistle of the wind, other noises from the outside can indicate that it is time to replace windows. New window technology helps to reduce noise pollution from outside of the home.
Wear and Tear – Do a visual as well as functional inspection of your window. If your windows look out of shape and have become difficult to operate, it is time to get them replaced. Difficult operation can indicate serious damage such as frame damage. If a window is damaged, you can be certain that you are not getting the maximum energy efficiency out of that window.
