The property I am looking at buying (over 200 years old), has been damp proofed 7 yrs ago with a 30 year warranty. My surveyor found damp in the living room, whilst we are in the process of getting this looked into, how can this be damp if it was treated?. Would it be just poor wokmanship on the treatment?

Dampness:
Numerous damp meter readings were taken throughout the accommodation with part mixed results – overall no significant rising or penetrating damp, except to the very base of lounge front wall where our damp meter indicated high readings suggestive of rising damp – we questioned the vendors who stated that a damp proof course has been installed with guarantee – we recommend formal confirmation of this via your solicitors and that the contractors be asked to return to check damp readings – we would like to add that elements of rising damp will not adversely affect the building structure. We also found signs of condensation factors (relating to the balance of heating and fresh air ventilation and also natural air circulation) – any black mould found should be treated with fungicidal product.

I would not rely on any surveyor who puts a normal meter on the base of a masonry wall and cries "damp".
And just to highlight his own incompetence, he then states that the condensation found is related to heating and ventilation, and not to the [supposed] rising damp - which would be evaporating into the room.
Why could it not be condensation forming on the naturally cold area of running down the wall?
There may or may not be excessive damp for reasons which may include rising damp or poor workmanship of the DPC installers. Would an injected DPC be a proper solution in any case?
But IMO, your surveyor has not satisfactorily ruled out all the other possibilities, and is just passing the buck. Why should a surveyor, paid to survey, ask for someone else to return to "check damp meter readings"? What a joke
The DPC warranty may not be transferable, and what happens if the installer returns "to check" the DPC and says it is all OK?
