How do vinyl windows go bad?
I’ve seen many references, here and elsewhere, to how vinyl windows don’t last very long, especially cheap ones. Well, I have cheap vinyl windows from the early 90’s and it’s not clear to me that there is any problem with them, other than weatherstripping and looking less than glamorous.
So, how does a vinyl window go bad? Does the plastic literally just crack and break apart?
Is it the seals? Don’t seals go bad regardless of the window frame material? And the glass can be replaced anyway.
I want to know what to look out for.
