My name is Ryan Parker with Parker Home Renovations in New Braunfels, Texas and I'm going to teach you how to install or replace a door hinge. If you have a squeaky door hinge or one that is rusted shut and you simply need to replace it you can go down to the hardware store and find one that is the same type of hinge. They have different types, the rounded edge hinge and they have the square hinge. Make sure you look at the one that you had and try to get one that is comparable to that one. Now as far as designs and colors you have many to choose from. You can go from anything from a white hinge to a black hinge to chrome, whatever your preference is. After you pick out your hinges at your local hardware store, bring them back home with you and then what you'll have to do is you'll have to open up your door, try to get somebody to help you to hold up the outside of the door as it is open and then you can pop the screws off of the door frame side on all the hinges, take the door completely off the door frame and then what you are going to want to do is where the hinge connects to the door do the same thing. Take all the screws off the hinge on the door side and remove that hinge altogether. Then you get your new hinge and you mount them back on the door the same way you took the other ones off, set them in the mortise section, screw the screws back into the holes and then you'll have to hold your door back up and screw it back to the door frame and then you can shut the door and you've replaced your hinges.
