I am working on a house that is 70+ years old, It has barnboard covered over by aluminum siding. I have done many things including replacement window but this is new for me. We are renovating the kitchen and removing a vertical length window (standard size back then) and replacing it with a wider, shorter window placed above the kitchen sink. I would like to get a detailed list of things to do (in order) or a good video on how to do it.
Here is what I think has to be done, someone correct me if I'm wrong.
1) Remove aluminum to the top of the window
2)Obtain 48" wide 36" tall new construction window with nailing flange
3)Prepare framework for rough opening 49" X 37"
4)Install seal around perimeter of window
5)Caulk around the window flange and set in place on top of shims
6)Level the window and fasten to the barnboard
7)Foam insulation around the inside to rough opening
8)Install seal around perimeter of flange putting the top piece on last
9)Reinstall aluminum siding cutting to fit right into window frame.
10)Caulk around the window frame to siding
If anyone can help, post pics, video, whatever, it would be greatly appreciated.
Thank you in advance (from Ontario)
