Mold on vinyl frame inside
First of all I live in WA state and it's very damp here. These windows were replaced in 1998 and they're from a company called Alpine which is no longer in business. My ques. is why would the interior frame on the vinyl get moldy? Is it because they were not sealed properly? They were installed when it was snowing could that be why? Excuse me if I seem naive, but that's my guess. Anyone care to elaborate on this? Also, it's not happening on all the windows but still a few too many.
