What to Know About Rattling Windows

One common concern people have about their windows is when they start hearing them rattle. This can be a sign that something is not working as well as it should be, and it is something that you want to consider with care.

Rattling windows are usually caused by loose panes of glass. Over time, the putty or caulking that holds the glass in place can dry out, crack, and come loose. As a result, the glass may begin to move around, causing the window to rattle. In some cases, the entire window pane may even fall out. While rattling windows may be annoying, they can also be dangerous.

Here are some things that providers of replacement windows in Mountain View, CA want you to remember when dealing with a rattling window.

Something else that may cause rattling windows is loose sashes. If you live somewhere, that receives extreme temperatures, this can cause the sash to warp. A warped sash will not be able to grip the window pane as powerfully as it needs to, which can be a concern. A window pane that is moving about can get cracks or can even fall off completely and break. If the sash is loose, you must reach out to an expert for help. Sometimes, the hardware of the sash can be replaced, but other times, the whole thing needs to be redone.

Another cause of rattling windows is wood rot. If your windows are made of wood, this can be a common issue, especially if the windows are old. Wood rot can happen if there has been a lot of moisture or if the windows have not been maintained as well as needed. The rot causes spaces to form in the wood, making it warp. It can also allow drafts to make it into the house. If you see signs of wood rot or if you suspect this is the issue, you want to reach out to experts for help.
