Presently disagreeing with a letting agent responsible for a property I recently moved out of over a large wall crack. This crack was there (albeit smaller) when we took residence, and it has become worse over the tenancy period.
So far as we know we've done nothing to exacerbate the issue, but the agent and their contractor is adamant this is our fault: "... the crack is not settlement related. Basically the area of wall is made up of two sheets of plaster board and at the join the plaster board has been broken through ..."
I'd be grateful of any experienced opinions you might have - I appreciate it's not so easy to tell from a picture, but any guidance or background you might have would be useful both for myself in this situation and I suspect to others who experience similar.
