I am recently having issues with an internal door closing. The door is internal to my lounge and garage and appears to be pinching on the “strip” that runs around the door frame, specifically on the hinge side. (Sorry, I am unsure of correct terminology). This prevents it from closing. It only has started doing this since installing a wood heater, and when it is exceptionally cold outside. My theory is that the heat is causing something to expand therefore the pinching is occurring?
I am after tips on how to stop the door from pinching.
