Interior Doors Sticking or Failing to Latch

Interior doors that suddenly stick, rub against the jamb, or fail to latch are often mistaken for a humidity problem. When the pattern spreads across multiple doors on one side of the home, however, the true cause is foundation movement beneath that section.

The floor is tilting and racking the door frames out of square. New Jersey homeowners frequently observe this during the dry fall season, which rules out seasonal swelling. A foundation assessment typically reveals settlement that requires underpinning on the affected side.
