Course Background The aim of this 1 DAY COURSE is to understand why and how condensation, damp and rot occur in buildings and to discuss appropriate remedies. This comprehensively structured course draws on case studies in housing and other building types and is designed to appeal to new entrants to property maintenance and facility management and as a comprehensive refresher for existing practitioners. The content is also relevant to those involved in managing energy efficiency improvements.

Dampness in all it’s forms continues to be a source of common building defects. The course adopts a forensic approach to diagnosing and investigating the causes of these defects and provides solutions for remedial work and preventative strategies.
