Hi all, need some help with lintel above a window. Please see the photos. There is a 1m crack. I have removed some flaky bits and it seems that the crack is deeper than I thought. I can wedge a £1 coin as you can see on the photo. At first I thought I would just seal it but since the crack is big, I was wondering what people think? Can this lintel be saved or does it need to be replaced? There are no cracks above in the wall just this crack in the lintel itself. If it can be saved, what do I need to do? Can I inject something into it to seal/fill the crack before finishing the rendering? Any ideas/opinions are welcome.

Hi lydiaf
The crack is probably as a result of replacement windows being fitted and unlikely to be anything to do with the lintel. Fill the gap with a fine concrete mortar mix - if you can find one of the giant mortar guns they are ideal for this job.
