Hello,
See couple of picture.
Pretty clueless about DIY and if that should be a concern or not hence posting it there to gather your thoughts and expertise.
As you can see on the picture, it seems that we have some kind of power by the side of the windows.
Background on the property: converted flat ground floor flat (with basement flat below)– Windows are double glazed aluminium so quite old but still doing the job.
What do you think? And is that a concern? It was there a while ago and I just whipped it out.
Many thanks in advance,
