Hello! Just wondering if anyone knows how I should finish the 4 inch gaps at the bottom of my basement's wallboard (between the wallboard and the floor). There is no framing or furring strip down there at all (nothing to nail/screw to at this point). I know there must be a simple answer. Also, what are typical code requirements for basement egress? Am I prevented from selling the downstairs rooms (which are finished) as bedrooms if there is not enough egress? Can I count the windows? Well, sorry this is so long and thanks for any help!
