Hello,
renovating my first place.. so probably gonna have a few questions.
the first thing im unsure on is the floor/ceiling joists on the first floor.
its a 1960's cavity wall house, and the joists sit over the over the wall. however there is some pretty big gaps between the joist of the wall, and i can feel the draughts coming through them. is this for ventalation or has the mortar erroded over time? whats the best thing to patch them back up? also notice some black marks which are only present around the end of the joists.. doesnt come away with mould/mildrew cleaner..
