Most homeowners know when it’s time to replace their windows. If you’re unsure, ask yourself these questions: Are your windows old or painted shut? Do you see foggy areas that will not wipe clean (seal failure)? Are the window frames starting to rot? Do your windows not function properly anymore? Do you have a hard time opening and closing your windows? Do your windows not lock properly? Are your windows single pane? Do you feel a draft near your windows? Are certain areas of your home colder than other areas? Are your windows more than twenty years old? If you answered yes to any of these questions, it’s most likely time to have your windows inspected.
