I ran into a problem recently on the back of my house where I have a bay window. The brick below the window was leaking water through mortar gaps and into the walls that caused some mold to form on the sheetrock. The slab was poured for the shape of the bay window. The window is about 25 years old and is a cheap single pane that I would like to just get rid of. My question is, Is there any way I can get rid of that part of the slab where the bay window sits and just run me a straight wall and install a regular window?
