Stud wall plate

[jen20]

Hi could anyone help please. After removing skirting boards and a cupboard we have come across damage to the internal stud wall plate. It looks like its had water damage for year from where the old shower was on the other side of the wall. Its dry but it has rotten in places. Does it need repairing or replacing?
One builder told me no, but I'd like a second opinion.

There is a crack at the top of the wall above the worst damage, not sure if this is related.
The last photo shows what it looks like where it hasn't been water damaged

Thank you

Sorry I've just seen the pinned post that says no queries, please point me in the right direction on where to post instead TIA

I've asked the mods to move it to building but you will probably get answers here

Thanks I have copied it on the joinery thread earlier as not 100% sure where it fits.

If its dry and no signs of rotting further should be ok, so could be removed if/whenever a larger scale re model is carried out. Just pack out the gap below if its as hollow as it looks

Thank you much appreciated. There is wood under but it looks like the wood on the side has come away but there is still wood touching the floor boards. Any recommendations on what I could pack it out with? Thanks again

Its difficult to judge the depth of the gap but plastic or even metal shims. I would probably ram in some repair mortar mixed with a little gravel if necessary.

OP,
There are bits of cobwebby strands - are they vegetation looking?
And occasional sparse patches of white slightly fluffy fungus showing?
Dry rot causes timber shrinkage - your plate is shrinking & curling.
But the classic cuboidal cracking of dry rot cannot be seen.
However, the underneath of the plate, and the far edge of the timber might be showing much more radical decay.
Do you still have the skirting board? Why not pic the far side of the partition?
Packing & wedging under the plate might cause even further movement of the stud wall.

The inside corner crack, & ceiling abutment cracking is possibly due to the shrinking and curling movement below. Whats happening with the RH wall?

OP, what are your future intentions for these walls, ceiling & floors - rooms?
Attempting a cheap repair would be hopeless given the above - the correct thing would be to open everything up, & then investigate what is exposed.
