There is a gap between the concrete window sill and the wooden box. Shall I just fill this in with filler or try and gun it in with silicone?
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.

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

Also staring at some sash windows - would lime putty be appropriate for limestone sill/sash gap and around a front door frame?

Or, in my case, digging out, treating with hardener, filling with burnt sand mastic and intending to go back to it and fix the wood at a later date.

I am sorting out a sash window at my girlfriend's and could do with some advice please. First time doing this.

The wood doesn't look rotten at all, other than one small soft mushy bit. (Last pic). Shall I just prime and paint over that, or try cut it out and fill it with wood filler? Would probably be a challenge to glue in a new piece
Cheers!
