Shortly speaking, no.
The C & G only carried out a "valuation" which specifically does NOT look at structure or anything of any serious matter. All the valuation survey does is say to the lender whether or not the property is suitable for a mortgage. It is up to you to instruct a surveyor to carry out a more detailed and/or in depth survey for you, not the lender.
Sorry, but this is not C & G's fault.
SHARK!
