Thanks very much! Anything equivalent to lime putty? Just so I can plough on today. Seen this at Screwfix but not sure if it is breathable

Looking at the same bit of work.
Acquiring the right materials in DIY quantity, in good time, seems difficult.
At least compared to what Screwfix etc will sell you.
Would be good to know who the DIY supplier of choice is.
cut it out and fill it with wood filler
Yes - or splice in a replacement piece.
If you just want the job done have at it with hardener but don’t tell airhead or Bobbo ;)

Anything equivalent to lime putty
That stuff looks like it's closer to sand mastic - its linseed oil and some sort of mineral, but could have all sorts of other stuff added that could make it less appropriate.

That looks like glazing putty to me. The lime putty isn't recommended for glazing it's called putty because it remains flexible once dry.

This would traditionally be done with burnt sand and linseed oil mastic. I wouldn't use silicone because you risk trapping moisture behind the silicone which will lead to rot issues. Lime putty would be good in this situation as it's breathable so any trapped moisture will be able to escape.
That soft spot could be the tip of the iceberg. It needs chopping out and treating / filling with timbabuild or repaircare.
