How to Level a Door Jamb
Leveling a door jamb is necessary for the door to function properly. An out-of-level door jamb forces a door to "stick" when closed, stops the door from closing all the way or latching, and can leave unsightly gaps between the jamb and door slab. Follow the correct procedure to level the door jamb and properly maintain your door. Does this Spark an idea?
