Our exterior door appears to have dropped so that the gap at the top is wider on the left (lock side) than the right (hinge side). This means that it's very difficult to lock the door. To lock the door you have to lift the door very firmly whilst lifting the door handle. Just wondering how to rectify this. There are allen keys on top of the butt hinges and small ones on the front of the hinges. Which way should I turn the Allen keys to raise the door hinges and door?
Any help would be much appreciated!
