This is a property damage claim. for which an action may be brought within 5 years. It would be a matter for small cliams court and you would not necessarily need an attorney. The plaintiff has the burden of proof and you have correctly stated the problems with proving value, which is an element of the claim. If damage could be proven (which sounds problematic also), the plaintiff is not entitled to the purchase price; only the cost of repairs (which requires some evidence).
