How can i fix this floorboard? When you stand on it it feels like it will give way. As you can see from the attched photo, someone has cut a floorboard about the width of a bike spanner shy of the joist. The floorboard goes under the wall and is only attached beyond that, so i think too big a job for me to replace it with a longer board. I cant lift the board much to get under it, is there a way of securing it somehow. Any help would be much appreciated.
