  1. 1

    Measure to make sure you have enough space for your new double door frame. The space for the new doors should be one inch wider and 1.2 cm (1/2 inch) taller than the frame. Also make sure the new door jamb is the correct size. Door jambs come in a width of 11.3 cm or 16.3 cm (9/16 inches or 6 9/16 inches).

  2. 2

    Place your new door frame in the wall. Slide it into place bottom-first, and then tilt it up until it is in the correct upright position. Make sure the jambs are flush with the wall.

  3. 3

    Use your level to make sure the top of the door frame is level. When you get it in place, hammer it in securely using the 3.8 cm (1 1/2 inch) nails. Place the nails about every 15 cm (6 inches) or so apart as you go along the top of the door frame.

  4. 4

    Hold the level on one side of the frame. Hammer in wood shims between the wall and the frame until the side of the frame is level. Once you have aligned it, drive the 6.5 cm (2 1/2 inch) nails through the frame, shims and partially into the wall stud to secure. Do this at both hinge locations and in the centre of the frame. Repeat on the other side.

  5. 5

    Operate the doors and make sure they can shut, stay closed, are level and have a 3 mm (1/8 inch) gap between them and the door frame. If they don't, pull out the 6.5 cm (2 1/2 inch) nails in the frame and adjust. Once they have achieved all of these criteria, drive the nails all the way into the side of the frame.

  6. 6

    When the frame is in place, add shims at every 30 cm (12 inches) down each side of the frame. Cut the wall shims so they are even with the wall.
