When Should I Replace My Windows?

It can be difficult to determine when you should replace your windows. However, there are a few signs that you can look for that indicate that it may be time to replace your windows. One of the most obvious signs that you need to replace your windows is if the windows are cracked or broken. Another sign that you should replace your windows is if the windows are difficult to open or close. If you notice any drafts or if you notice that the windows are foggy, this can also be a sign that you need to replace your windows. Finally, if your windows are more than 20 years old, you should consider replacing them. Even if your windows are not cracked or broken, if they are old, they are likely not as energy-efficient as newer windows.
