  1. Screw drivers

  3. An assistant for supporting the door


  1. Firstly, you need to remove door from its hinges carefully and if the door hinges have removable pins, remove the pin first before lifting the door out from its frame.

  3. Always check the bottom of the door when you have removed it from the hinges. This is to check whether it has been damaged or not because if it is, it definitely needs to be repaired. You can also paint the door\’s bottom edge to protect them from water.
