Do you think your window seal has failed, but aren’t sure? The most surefire way to know that your window has experienced seal failure is if you see condensation in between the panes of glass. If you have double or triple pane windows, window seals are generally very reliable, but pressure washing, scraping, or sanding your windows, or even just time itself, can cause window seals to fail.
When this happens, what should you do and how should you fix it?
