I have a pair of french doors with 2 fixed side panels, the cill plus small
areas of uprights where jointed into cill are rotten.
I'm considering cutting out and replacing the cill and splicing in new timber
in situ rather than remove the whole frame - it seems less work to do it that
way.
Is this the way to do it ?
Anyone had experience of this ?
Any suggestions would be gratefully received

John
