I'm in the process of buying a house and I've noticed some cracked brickwork directly above an RSJ where the kitchen was extended about 3 years ago. I'm still waiting on the survey (level 3), but I'm concerned that the surveyor will bottle it and not give a firm opinion. I'm attaching a photo of the crack as seen through the extension skylight and also a plan (not the most relevant plan, but all I have to hand as the local planning website is down for the weekend) with the location of the cracks circled in blue.

Anyone got an informed view on how concerned I should be?

It’s possible the crack maybe the result of poor RSJ installation - ie acrows over tightened or steel not packed up properly allowing subsequent settling…..and now it’s all stable and just needs local repair.

or not….

Im sure survey will pick it up

The surveyor will recommend a structural engineer looks at it.

I think Notch is right though - badly packed above the beam, slight movement at the bearings, or slight deflection of the beam following installation.

Your surveyor won't be able to comment on things outside of his expertise. So if he is not qualified in structures, he will just recommend a further report by a structural engineer.

You should be concerned until told not to be by a suitable person.

Following up for anyone interested. The surveyor said it wasn't a sign of a great job done, but it also was not a structural concern in his opinion. Expanding on that he said about 90% of the extensions to Victorian properties that he's seen have presented similar settling cracks. His advice was to repoint/fill and then keep an eye on it.

Cracking above the level of the beam is not usually serious; cracking below the level of the beam is when you need to be concerned.
