Cracks around replacement windows (ed.)

[Pjwoodstreet]

Hi all,

I peeled back the wallpaper on my renovation project (1930’s semi) to find quite a few crack surrounding a window on the staircase. The window looks to have been installed 20 years ago. I also know that a stairlift was also installed on this wall.

Should I be concerned about these cracks?

Thanks

Pics would be handy. If the wallpaper was old and flat then probably nowt to stress about.

thanks. Now with photos attached

That window may be nearer 30 years old (external beads have been off the menu for some time now).
Quite possible there is a timber lintel on the inner side of the wall which has moved a bit now it's not supported by the original timber window.
Any sign of similar cracking on the outside?
That plaster looks fairly rough- it would be tempting to knock out a vertical strip above the window so you can see what's actually in there.

no signs of cracking on the outside. That would make some sense as the cracking seems to focused around the windows and it looks like the top edge of the window surrounding dipping towards the middle.

I’m going to knock out a strip and post a few more photos.

Thanks for the advice
Pete
