Window Frame Falling to One Side

[HumanAstronomer3194]

I noticed today that the window frame (that spans two rooms) crooked and there is a big gap between frame letting day light in. It looks like it's falling into the internal cavity of the room. Would this be fixable without having to replace the windows/frame etc? I was thinking of exposing the internal window sill to see would it give me an idea of how the whole thing is held together.

Room A: Gap above window frame

Room A: Frame isn't level with the sill

Room B: Crack under the internal window sill

EDIT:
Found an older photo before it fell.

It looks repairable to me, it just hasn't been installed very well originally.

If it had been mechanically fitted ( eg screwed, ) to the walls then it shouldn't have dropped at all , open the window and see if there are any screws going into the walls. It may still be on ' straps " in which case it's mechanically fitted too.. see if the frame is physically loose

So I opened the window to see if there was any screw going right through but I cannot see any.

Can you physically push the window frame back up to close that gap?, if so you may get away with ' packing ' it underneath but that will depend on the construction of the house. If you can push it up , and pack it, then get some frame fixers ( concrete screws ) that use a t30 torx bit and screw that frame to the building. Any gaps left at the bottom could.be filled with fixing foam and then , depending on the size , either silicone or a trim then silicone.
If you cant move it up then more investigation will be needed

However when I looked more on the outside I seen something more concerning. It's not just the window the whole front part of the house has dropped down by 4cm.

I don't know if the black marks on the bricks here mean there has been water ingress which has compromised the beam running across here holding up the façade.

Obviously I cant see the whole property but pictures.2 and 3 show the line of silicone and where the cill now sits, and yes its about 4 inches ... but before you look at subsidence , that cill.is joined to the window, so it may , hopefully , still.just be a case of the window dropping . If its a subsidence issue you will.have more cracks visible around the property I suspect... double check and see if you can push that window back up

That last pic you posted does not look good. It looks as though you have a serious structural issue with the property.

This is the outside of the house. I'm thinking that has happened the outermost joist which is holding up the façade has failed. I don't see any other cracks inside the house.

Both top and bottom window sills have dropped by 4cm. I'm guessing if I can somehow remove the outer panel I might be able to get a view of the outer joist.

Seeing the overall set up, think the only option is have the window frame removed, which include the yellow section below the glass section,and hope it's just a failed timber and nothing more setious

The window is set so far back in the opening that any mechanical fixings would have gone into the cavity hence why they didn't bother

I was able to lift the window sill and I don't think there are any structural issues with the house. I can see the outer joist looks to be fine and covered in felt. But I'm struggling to find what the window is attached to.
Photo looking down from the window sill;

I can see one of the screw got pulled out but it looks like it was only drilled into wood and not into the brickwork.

What I'm thinking of doing is getting two or three acrow props to hold/push up the façade. Then with that I could get longer screws to drill into the blockwork. Unfortunately it's all one big unit so it's going to be very awkward to move.

I'm going to try and remove the bead on the yellow panel so see if I can a better view to see of how it's attached to the house.

Well you can already see in your second picture that the screw is going no where, there's your issue. Suggest longer screws, angled to attach the actual building, ideally fixing foam too but you're not going to get that in.
Good news about being able to lift it though and no visible damage to what's below the window. By the looks of it , a poorly fitted window!

I opened up a panel on the other side of the house to see if I could get an idea on how that is held up. I'm starting to think the whole window frame is held from the top instead of the bottom due to the lack of a window cill. Any suggestions on what I should do next?

I cannot see anything obvious how the frame is being held up.

I can see the odd screw but it doesn't seem like anything that would hold up the weight of the window

Just for clarification the photo I uploaded with the screw ripped out was from the top of the window. So is the weight being held from the top instead of the bottom?
