Hi all,
I've recently moved into a 1935 3 bed semi with a single storey rear extension built in 1982.
Ive been investigating the suspended timber floor in the rear living room with a view to insulate. A third of this room extends into the modern extension. I fully expected the flooring to be osb in the extension as a continuation of the existing floorboards.
Upon removing a section of osb I find timber joists just floating on wedges, not tied into anything. Furthermore the wedges range from wood, tile and slate. The joists are level in themselves but not each other, and certainly not with the existing floor.
Is this normal practice?
I'm now leaning towards installing a timber ledger against the wall (dpc between it and said wall) with m16 through bolt anchors, and then tieing in the joists to that? That way I could get the ledger true to the existing suspended floor joists and get a level floor throughout.
I also intend to replace osb for like for like floorboards so this would benefit.
Sorry for the awful quality pics. The pic with the level shows the original external wall inbetween old and new joist.
Any thoughts?
Thanks, James
