High energy bills indicate that your home has an air leak somewhere. Often, the culprit is the windows in your home, especially if you have older windows. The following five signs indicate that it may be time to schedule a new window installation so you can update the energy efficiency of your home.
The most obvious sign of a leaky window is drafts. If you feel a draft near the window when it is closed or if the curtains tend to move around on windy days, then there may be a draft. Some drafts are obvious, such as when visible air gaps form around warped window frames or failed sealants. Other drafts may not be immediately visible, which can be the case if the glass has become loose in the frame.
Condensation on the interior of the glass or between the panes means that moisture is somehow making its way through the window. This can be due to air leaks around the frame, failed weatherstripping, or loose glass. For double- and triple-pane insulated windows, condensation between the panes means that the insulation has failed completely. Weather stripping can be replaced, but most other issues will necessitate new windows.
3. Dust and Grime
Check your window sills after a windy day, especially those on the side of the home that received the brunt of the wind. If you notice a buildup of dust and grime on the seal, there could be air gaps around the window that allowed the wind to force the dust inside. The glass may also tend to get grimy on the inside around the edges of the windows as a result of an air leak.
4. Operation Issues
Your windows should open and close smoothly and easily. If the window tends to get stuck or needs to be forced, then there is likely some damage to the frame. A warped frame will no longer seal fully when closed, which will allow drafts and air leakage to occur. Wood frames are especially prone to warping, but any type of frame can experience it.
5. Sound Transfer
If outdoor noises seem louder than usual, then the cause could be air leaks allowing more sounds inside. As window seals fail, sound transfer becomes more severe. The glass may even seem to shake inside the frame if the damage is severe.
