So, When Is It Time to Replace Your Windows?
There's a few common signs that your windows may need replacing:
Drafts or noticeable cold spots near windows
Condensation or fog between panes
Difficulty opening or closing
Visible warping or damage to frames
Increased heating or cooling costs
If you recognize any of these issues, it might be time to explore a window replacement.
