I had Efficiency Matters return to frame in the back door with 2 x 6’s. The wall there was so crooked that the first installation had the door sticking out 2 inches at the top inside and almost 2″ at the bottom outside. Not sure how I was supposed to seal or side or drywall that! I thought the solution was to straighten the wall with 2 x 6’s and re-install the door.
The new installation though did not solve the problem of lining up the new door to the plane where the siding will go. That is because the wall is crooked. Setting the door so that the bottom hit the plane of the siding meant that the top had to be out of line. Notice the old polyiso sticks out over the brick edge of the door.
This left me with the problem of figuring out how to line up the new polyiso behind the door so that the siding can be installed in one plane. I noticed that on the right side of the door, they had installed the polyiso INSIDE the 2×4 in the corner. They had spray foamed it into place. So I realized that I had to inset the new polyiso inside the 2 x 6 door frame and under the upper wall frame to line it up. In order to do that I had to tear out the two supporting 2 x 4’s above the door. Luckily all they support is the drywall framing and we can do without them.
I had to remove the awning frame to take off the upper siding and I split the boards to get them out from underneath the 2 x 6 trim on the top. Underneath is some polyiso where the old wall plane was so I’ll have to abut the siding under the trim and up to the old polyiso. But it is at least mostly in one plane now.
