Advice, possible wall movement after double glazing replaced

chris_h16

Hi
Just a bit of advice.  Just had full house double glazing replaced, old was wooden frames, new UPVC. Picture attached, do you think this is just cosmetic from getting the old window out etc or does it look like movement/sagging of the wall above the lintel?  Its worse across the window length and tapers off at edge of window.  I ask as its not just a crack between coven and wall but the material under the coven has uniformly dropped out/down by approx 3 or 4mm.  There is also cracks and movement above the wood batten the curtain rail is attached to. I was thinking of checking when this snow stops of looking at the wall outside as if there has been movement/sagging it would show outdoors?

There's not enough context here. How old is the house? Do you know what the construction is? Is the cracking at lots of windows, or just this one? How big is the window?

So, the answer is: maybe? If it's an old enough house that didn't have sufficient lintels/ they are damaged, then the windows could have been carrying some load, in which case this is something you need an engineer to look at. It's rarely a problem, but that's not the same as never.

Hi
The house is brick and built 1986.  Its only this window.
I believe the lintels are a metal few mm think from what I can see on the outside.
