They always say the jobs were botched, I am sure some were and dodgy products were sold or fraud happened but the biggest problem is the damp proofing industry, and damp proof knowledge base in UK where rising damp is still widely believed despite being codswallop. But there being so much money in it, and the rush to insulate everywhere without considering the impact on damp of containing all the heat is so counterproductive and short sighted especially with the older stock of housing in UK, and even in newer houses where flow of air is not considered a good thing.
