Installing New Joists and OSB Sub Floor (AGAIN)

A few weeks ago we shared our experience of making a massive mistake. Today we’re going to fix it.

During our first attempt we replaced some rotten old joists with some fancy new timbers but in order to make them fit we made the classic mistake of cutting notches in either end and in the middle. This was so the new, larger dimension timber would fit around an existing stud wall below and wall plates on either side of the room. But this was a terrible idea because we had essentially weakened the joists and they would not be structurally sound enough to span the gap.

There are many ways that this problem could be solved but the easiest solution for us was to do it again with new wood. And that’s exactly what we’ll show you in this video.
