In winter, when humidity drops and the dry west wind blows, the wood contracts. The door closes well but there is a visible gap between the door and frame, allowing air and noise to pass through. This is the natural cycle of wood and can only be avoided with two things: either replace it with a MDF or multi-layered door that doesn't move, or learn to live with it and adjust the hinges periodically. Traditional knob hinges, those seen on old construction doors, are not adjustable. If the door rubs, you have to shave wood with a plane or replace the hinges with modern adjustable models. Shaving wood is the usual solution when the problem is seasonal. We remove 1-2 mm from the rubbing area, seal the cut, and the door closes again. We identify the real cause (humidity, settlement, worn hardware) before acting.
