Step 1: Prepare the Doorway

Before you can install the door, you need to prepare the doorway. This includes removing any existing door or trim, and making sure that the opening is square and level. If the opening is not square, you may need to shim the jambs to make it level.

Once the doorway is prepared, you can begin installing the jambs. Start by placing the jambs in the opening and leveling them. Once they are level, nail or screw them into place.

Next, you need to install the door. Lift the door into the opening and align it with the jambs. Once the door is aligned, nail or screw it into place.
