If the latch misses the strike plate, the door won't remain shut.The Cause: Shifting frames, paint buildup inside the strike plate, or a misaligned deadbolt hole.The Solution: Check where the lock strikes the strike plate. Often, merely moving the strike plate up or down by a fraction of an inch solves the problem. A file can also be used to slightly broaden the strike plate opening if the lock is catching on the edge.4. Foggy or Condensation-Filled Glass PanesDue to the fact that French doors are mainly made of glass, seal failure is a common long-term concern.The Cause: The hermetic seal on double-pane insulated glass has actually stopped working, permitting moisture to seep between the panes.The Solution: Unfortunately, defogging packages are typically just a short-term fix.
