I recently attended a property in Hampstead London, to survey a dry rot problem, a terrible thing to find in your home, this being caused by the ingress of water from a new terrace roof, we were glad to give the first survey free, but we made a small charge for a much more in-depth destructive survey, in order to form a plan and estimate for the works. take a look at the images,

the client turned out to be lucky as the dry rot had not reached below the floor, although it had caused substantial damage to the window,.floor and skirtings, they were also lucky to be covered by the insurance policy they had in place, as this is sometimes a problem.
