[QUOTE 5322322, member: 9609"]what's going on in the corner with the damp ? where is the damp coming from, is it rising or coming from something leaking, that needs to be sorted first,
Doesn't look like dryrot but that joist close to the wall - any growth on that?
the other joists just need a bit of damp proof membrane to sit on, and the one with a bit of rot will probably be easily fixed with a wooden plate bolted onto each side of the good timber, and a bit of damp proof membrane between it and the wall.
but that corner needs to be sorted out, whats happening on the other side of it ?[/QUOTE]
Main issue is simply the wood on the small wall supports was set in motar, so no damp proofing.
I'll fit dpc to the new floor support,it should be ok with that.
9 inch brick work and a concrete sub base, so no rising damp protection.
Exterior walls are good so just the internal damp protection required.
I'm going to use treated timber and caber floor for the new floor.
Way to expensive to go traditional.
Should be about £250 to repair it, then decor and new carpet ect.
