Replacing doors inside your home requires removing the door from the opening. Most doors have simple butt hinges, while some use spring hinges. Spring hinges force the door to close after opening much like a door closer. When removing a door that has spring hinges, you must release the tension on the spring inside the hinge. Once you release the spring tension, the door removes much like any other door in your home.
Close the door. Insert an Allen wrench into the adjuster at the top of the spring hinge. The adjuster is where the two leafs of the hinge come together. Hold the Allen wrench steady in one hand.
Pull the adjustment pin from the side of the hinge barrel with a pair of needle-nose pliers. Slowly rotate the Allen wrench counterclockwise until you can insert the adjustment pin back into the hole in the hinge barrel.
Continue removing the adjustment pin and allowing the Allen wrench to move counterclockwise until there is no more tension on the spring hinge. The Allen wrench will not rotate on its own when the tension is fully released. Repeat the process for all the spring hinges on the door.
Open the door completely so you can access the screws securing the hinges to the door jamb. Remove the screws with a Phillips-head screwdriver. Begin at the centre hinge and follow with the bottom and top hinge.
Pull the door away from the opening and remove the screws securing the hinge to the door with the Phillips-head screwdriver.
