I absolutely agree with the reply by ScotlandX. We had an owner demand we get an engineer out to inspect one of their walls as they were scared that recent rains had weakened it. We refused. I inspected the wall and there was no identifiable damage/weakness. The owner threatened to sue if anything did happen.
I believe it comes down to a reasonableness test. The OC in the absence of evidence to the contrary is entitled to accept things are sound. Contrast this with a situation were the OC should have known eg., a repair to a balcony that left the balcony weakened and not up to current building standards.
Danih, unless there is an obvious defect it is not up to the OC to do stuff ‘just in case’.
A cynical warning against telling her to get her own investigation/report. My experience is that if you are paying it is not difficult to get a report to identify ‘potential’ defects.
