Last minute survey worries

We may have to get an additional specialist survey to examine the braces which hold the cavity wall together. Apparently cavity wall houses of this age were often braced with a metal which corrodes (Duh!). The danger is that in time the outer wall falls away from the internal one. If they are indeed not adequate the situation can be fixed but may have implications for the price of the house - and consequently may delay the operative date set for tomorrow.
