Replacing a door on your home, or repairing the door jamb, usually requires removing the door hinge. Most doors in homes use a butt hinge. A butt hinge is two separate flat leafs that connect together in the centre with a hinge pin. Unlike many hinges, the butt hinge requires removal of the hinge pin to properly remove the home door hinge. Failure to remove the hinge in this manner can cause damage to the connecting points of the hinge. Remove the door hinge properly to ensure that the door will operate smoothly when you install it back in the jamb.
Open the door at a 45-degree angle. Ask a friend to grasp the door handle on both sides of the door to hold the door level while you are removing the hinge pins.
Insert the flat-head screwdriver between the head of the pin and the hinge, on the lower hinge. If necessary tap the handle of the screwdriver with a hammer to position the blade under the pin. Pry the pin up as mush as possible with the screwdriver. Place the claw of the hammer under the head of the pin, and pull the pin straight out of the hinge.
Remove the pin out of the upper door hinge exactly as the lower hinge. If necessary, ask your helper to move the door up or down to alleviate binding the pin. Remove the centre hinge pin last, if your door has three hinges.
Pull the door away from the jamb. Remove the screws securing the hinge leafs to the edge of the door and the door jamb with a Phillips-head screwdriver.
