Depends on your definition of "no-name." The windows are Accuweld,
which, while not in the Pella/Anderson/Marvin league, is a large
company that's been around a while.
The fix should be covered under warranty, except for the all the little
escape clauses like "you must send in this card within 30 days of
installation to validate the warranty." Uh, never got a card nor heard
Fortunately our installer is a good firm and I am hoping they stand by
the product they rep.
