We had hoped on replacing the windows (old wooden frames with poor
aluminium
double glazing) at some point - but if the structure of the house pretty
much depends on the windows being replaced, then it may be more urgent and
important to get it done sooner rather than later.

Any thoughts?

Thanks

Sounds like a replacement window is in order David,
I'm not sure a repair is possible, to get the window out would require the
removal of the glass in most cases.
Send for the window fitters !!!!!!!
I put hardwood bay windows in my last house, stained them, beautiful
!!!!!!!!
everybody complimented on them. This house has upvc plastic and not a patch
on wood.
