Replace parts of a wood window

Not completely with you here Kris. (?) You need to replace the whole window casement ? Or is it just the sashes that hold the glass ?

How old are the windows ? Do they have lift out fillets and hinges for cleaning purposes ?

Just the sashes, it fills the whole window space.

They are screwed infrom the inside.

Ah Ha !!! So the whole window is a dead pane of glass and doesn't open ?

If it is, then just take the glass out and fit a matching astricle in the position you want your opening pane to be. You might even get away with having the exsiting glass cut down to size and re-use it.

But you don't need to take the whole thing out, just the glass. You then cut the frame where the glass sits in and fix a new piece of timber across where you want the opening pane to be. Get the big piece of existing glass cut down to size and re-use it.

I'd check the price of a new window first. If you're close to a stock size, it would probably be less hassle to go right back to the brickwork and replace the lot.
