1. Remove the Old Door/Frame before replacing the Metal door Casing

  • Take off the surrounding trim carefully if you wish to reuse it.  Using a pry bar, gently lift the trim free of the nails and put it in a safe place.
  • Using a circular saw, cut through the nails holding the old door piece to the frame and slide the door out.
  • Saw off and remove the studs around the door’s opening. Then, remove the drywall strip or panelling on both sides so you can reach the door frame.

2. Measure the Metal Door Casing

Using a tape measure, measure the door and pencil in the width of it on the horizontal boards that join the top and bottom of the wall frame. Also, pencil in the height of the new door on the wall studs.

3. Cut & Measure

  • With a circular saw, cut a pair of 2×4 studs so it will fit between the horizontal wall frame boards and insert them. Nail the top and bottom boards in and make sure they are nailed in diagonally through each side.
  • Now cut another pair of 2×4 studs to the height of the exterior door and put them next to the just-installed studs. Nail them to the studs and the boards at the top and bottom wall frame.
  • Find the distance from the studs. They should be 3-3/4″ greater than the width of the doorway, and cut a single 2×4 stud to that width. Put it on top of the studs and nail it to both sets to create the header of the exterior door frame.
  • Again, measure the distance from the header to the top of the wall frame and cut one 2×4 stud to that height. You’ll want to put it vertically onto the header’s midpoint and then nail it through the header and secure it.
  • Nail diagonally through and into the top frame wallboard to create the cripple stud for the door frame.
  • Now that you have completed the new door frame, you can refinish the surrounding areas if necessary.
