ᐅ Cracks in the Lintel or Brickwork Above the Window – How to Address?

Hello everyone,

We recently purchased a single-family house and will soon be replacing some old windows.

We have noticed cracks above the window lintel on the west side of the house. The building was constructed in 1989. It seems that the lintel above one of the windows has settled.

What could be the cause of this? What would be the best course of action? Should we leave it as is for now? Is there anything we can do ourselves? Would simply sealing the joints be sufficient?

The pictures are useless like this (close-up detail instead of overall context); the interior side is completely missing.

Excuse me? Which interior side?
Are you asking for a complete view of the house facade?

On the one hand, it is necessary to determine the alignment of the offset within the brick facade, including the surrounding area, in order to identify a possible cause. On the other hand, of course, the interior view of the masonry is also important, to see how the issue might appear from the inside.
(By the way, in my case the photos do not display at all. This is usually due to an incorrect way of attaching files in this forum.)

I can see the images both on mobile and desktop, but without any context, they don’t really convey anything. Quick click.
