The previous homeowner installed built-in armoire cabinets and bookcases that I plan to remove. In order to facilitate the opening of the armoire cabinet door, they cut into the window sill and apron with a Sawzall.
See photo here:
The way I see it, there are three options for repairing this:
1.) Try to replace the entire sill and apron. I'm not a carpenter, so this might prove to be impossible.
2.) Use some kind of filler compound / putty to rebuild the sill and apron to an acceptable level.
3.) Use compound / putty to rebuild the sill and replace the apron, which should be easier to replace than the sill itself.
I would appreciate any advice or help you can give me in making this determination. Thank you!
