In this episode of we explore one of the most common but often misunderstood issues in London housing, the effect of shrink–swell clay soils on Victorian terraces.

Through the example of a typical two-storey mid-terrace, we explain how much such a house really weighs, whether clay can “lift” a building, and where the real danger lies. We discuss seasonal shrinkage, tree roots, shallow foundations, and why one house may crack while its neighbour remains unaffected.

With clear analogies and references to scientific guidance, this episode demystifies the phenomenon of clay movement and makes sense of what surveyors see on the ground, movements measured in millimetres but with consequences felt in everyday living.

Welcome to today's podcast, where we delve deeply into a widely misunderstood but crucial topic in residential property surveying: accurately detecting and interpreting dampness in buildings. We'll explore why moisture readings alone can be misleading, what other essential factors must be considered, and how a comprehensive understanding of moisture dynamics can help us avoid costly errors and confusion.

Explore how roof coverings in Britain evolved from thatch and clay to slate, felt, and modern composites. This episode examines the materials, systems, and design choices that shaped roofing practice, including conservation challenges, structural risks, and common survey observations. Ideal for trainee surveyors or anyone keen to understand why roofs fail, how they perform, and what they reveal about the buildings they protect.
