Rising Damp is usually identified by seeing tide marks along the base of the wall just above the skirting board. Paint, and in bad cases plaster will be bubbling and falling off the wall. Early signs and confirmation of rising damp can be identified by a professional by using the correct measuring tools, such as a moisture meter with prongs to penetrate the plaster.
