Our home is 5 1/2 years old and we have a Vetter Picture window above our front door. We recently found out that the window pane seal is broken and not only is moisture coming in between the glass but the wood around the window is soft and rotting. What can I do? Does Vetter have a warranty that will cover their window if the seal is broken, what is their warranty? And if not, can this be fixed without replace the entire window? Any suggestions on the directions here that I should take? We are second owners of the home.
