I'm buying a mid-floor flat in a 60's purpose-built block with concrete floors. Some of the celings are cracked and sagging a little but the mortgage lender's survey makes no mention of them. I'm convinced there is no subsidence to speak of and I started the purchase making an allowance for replastering the ceilings if required. I will get a good builder or two to advise on what need to be done when the purchase is complete. In the menatime, has anyone any experience of this kind of problem and what was the cause and the solution?
Thanks. K
