This has developed over years in a house I used to rent out. I’m moving back in and getting it right. Noticed these crack is or just list mortar or something more sinister? It’s a traditional muds 2920s semidetached. There are now crack on the inside of the upstairs bedroom wall.

You need to send one or two pics from further back so that we can see the context.

I think it looks much worse than it is due to the loss of the pointing which hasn't been raked out deep enough.

Maybe the opposite to subsidence? Perhaps the expansion on the failed concrete sill has pushed the window and some of the masonry upwards?

It could be long-term movement of the arch pushing out on the abutment. The bit of wall on the left of the doorway is very narrow (one, or one-and-a-half bricks wide?) and would not normally be regarded as OK to support the sideways thrust of the arch.

Would it affect other houses too? Only they look ok. It was built in 1926.
What’s the remedy if this is the case
