Door Installation

I will be installing an exterior door unit in place of a window. The house is wood frame construction with brick veneer. The RO width is correct for the new door and the window is tall enough that I will only have to remove two courses of brick for proper height. My question is how can I best seal the jamb and threshold to ensure no water infiltration. Can any type of flashing be installed in a retro-fit to make sure that any water which does leak within the wall find itís way outside?

Removing two courses of brick may put you in trouble. The top of the window will probably have a steel lintel plate stretched across it to hold the brick. If you remove it, your brick from the window up will fall in. The header for the window is set right, so what is your plan for the door header? Cutting the opening, installing the door is minor compared to what you will have to do to ensure the stability of the veneer. If you get to that point, Flash over the door frame and up under the top course of brick with metal flashing, lay a bead or three of silicone under the threshold so when you set it in place they will squish together. Have you taken into consideration the brick mold and the extra cutout along the top and edges you will have to make?
