Gaps in corners of wooden windows

[arbit]

Hi guys,

I've been wondering about this for a while now so might as well ask on here:
We've got (many) wooden windows which we had recently painted both internally and externally.

I've started replacing the seals in a few rooms as we've got a lot of problems with draft and noticed how large the gaps of these windows within the frames are, particularly in the top right/left corners. Rather than me poorly fitting meters and meters of draft excluders to stuff these gaps, could there be some trick to adjusting the windows within the frames or to change sth to get rid of these pesky gaps?

Here are a few pictures of what I am dealing with:

Any help is appreciated

So you have timber windows with friction stays and espagnolette locking

The windows also have hinge protection clips.

I’m not entirely sure but the windows look like they are high performance flush style and they have an aquamac 21 weather seal around the sash for the outside rebate and a seal fitted into the frame to seal on the inside

It’s a bit hard to advice from the pics, but it looks like the window sashes have shrunk (and the frame has pulled apart a bit due to being screwed in too much into the wall, opening up the transom to jamb joint. If so the problem you have is that you can’t adjust on the hinges because the espagnolette lock won’t meet its mushrooms.

It also looks like the sashes have twisted a bit.

Personally I would think, if it’s possible, to replace the frame rubber - which is set in to a groove. Reddiseals and Quest sell draught seals to suit (you might need advice on here to know which one.)

Maybe you could replace the outside seal

Are these Bereco windows?
