How many damp-proof courses are needed?

Our Building Surveyor Sean Steer has just carried out a Full Building Survey in Horley on a Victorian property which has no less than 3 damp-proof courses – all in the wrong place!!

The original slate DPC was believed to have failed and two more injected chemical damp proof courses were put in; both unnecessary and both in the wrong place. It just needed the ground level lowering and ventilation improving. Good practical advice was needed then there would have been no need to spend money unnecessarily.
