The causes of mold growth in buildings are diverse and often a subject of disputes. The updated and revised new edition illustrates the concrete relationship between symptoms (damage) and the causes of mold infestation. The book provides detailed assessment criteria, presents typical manifestations, medical risks, and relevant measurement and testing procedures. Comprehensive explanations of the technical, legal, and medical contexts enable the selection of appropriate investigation methods and remediation procedures, clarification of liability issues (tenant/landlord), and ultimately the assessment or prevention of health consequences. Numerous illustrations and tables, as well as legal reasoning in cases of mold infestation, discussions on mold-like damage patterns, and an overview of various aspects complete the work.
