I'm fitting a new allimim/UPVC back door which is the size of
existing internal door frame but I have to remove the metal upstand
strip in the existing wooden cill ..... not sure what the correct name
is for this
I can't see how this is fixed into cill or the depth etc. and could do
with some advice how to remove it to make way for new door frame.
Is it a hacksaw or chisel job ?
Any help would be most appreciated Cheers.
