Stepped Crack

[peter9191]

Hi all,

Anyone have a view on this crack?

Not very wide, is it just the pointing detereorating? Seem to have on on each corner of the house at the rear. House built in 1980's.

Forgot to add, no internal cracks in the upstair rooms

A pic from further back, showing the context, would help bigly.
It seems to be at roof level (?) and the corbel (stepped bricks) seems to have rotated a little and pulled away slightly.
How long has it been there?

Yes its a roof level, hopefully the other pics will give a better idea.

No idea how long its been there, been in about a year, wasnt mentioned on level 2 survey.

If its at both corners on the rear elevation (and not on the front?) could it be thermal expansion if the wall is south facing?
The corbels also look to be badly-detailed as they project in large steps, which would have made the brickwork slightly unstable to begin with. If there are any similar houses either side, try to see if the adjoining properties have similar cracks, which might indicate a design fault.
Hopefully some of the brickies on here will come along to offer suggestions?

Yes both corners on rear, the right looks more like mortar deteriation and doesnt come down as far. The rear elevation is south facing. The front is completely fine.
