Hi all. Looking for a bit of advice please. My wife and I had a ~4m RSJ installed under this wall approx 12 months ago. All spec’d by SE, signed off by BC etc. I have never noticed before but over the weekend I noticed what appears to be a small diagonal crack approximately 5ft above where it was installed (see photo). My wife and her old fella who’ve lived through a couple of construction projects are adamant it’s a settling crack and nothing to worry about. But if they’re chilled out then I’m on the other end of the spectrum. You guy’s live an breath this stuff, anything to be worried about? Thanks.
