    Thoughts on these cracks, same lintels used on the whole estate. (circa 1970's) but not seen these cracks above other windows on same estate. Just a messy patchup job of something more severe?

    Also at the rear some cracks near the corner of the house but don't penetrate below the DPC

    Next door their rear corner has similar cracks but not as apparent

    Put up some pictures of other houses on the estate with those "lintels".

    Maybe something to do with the lintels having no bearing at each end, and resting on the crappy uPVC windows that have replaced the timber originals that used to hold the wall up at those points...

    That cracking is not related to lintels. But I suspect that the OP is just a buyer after a free survey.

    Cracking IS related to lintels (and common on the same estate), thanks Stuart45, exactly what I thought. Nice to get a proper response from someone.

    Of course it's related to lintels. The boot lintels have rotated because they are no longer getting any support at the front.

    After seeing the boot lintel type that Stuart45 linked to I would agree some of the cracking (above the lintels) is probably due to them. However there is additional cracking that in my opinion is nothing to do with the lintels. Fortunately all the cracks seem to be very minor made worse in a lot of the pictures by a bad job of repointing that also uses mortar of a different colour which emphasises the issue. The worst is the middle picture on the low corner. That cracking is indicative of some foundation movement albeit very minor at the moment. I would be wondering if there any leaking drains or supply pipes causing that. As with any cracking knowing the history of the building is relevant to know if the cracks are live or not. Recent cracks would be a concern, old but stable ones probably not.

    The bricks look like they may be calcium silicate ones, which were known to have shrinkage problems in the past.

    LOL. Sorry I missed this gem!

    So how does rotation on the z axis cause movement on the x axis? Are we sharing the same universe, or are the rules of physics different on this estate?

    Isn't it.

    Does it just need to conform to what you supposedly already know, to be proper?

    Are you going to be putting an offer in now? Anything else we can help with?

    My 9 year old grandson knows the answer to that one woody, as he plays Minecraft whenever he gets hold of his mum's tablet.
    It's to do with the thrust from the Y axis on the X which transfers back to the Z rotating the Y back on the X and cracking the joints.
