Welcome to Talking Conservation, where we talk about all things related to our built heritage. Whether you own an historic building, are responsible for a heritage site, or are a professional consultant, contractor, or simply interested - this is the place to find out more.
We discuss various matters and conduct interviews with a wide range of people involved with our heritage in some way. This includes architects, surveyors, archaeologists, conservation officers, contractors, conservators, historians ... the list goes on.
We are interested in and talk about any aspect of heritage; not only listed buildings, but all older and traditionally constructed buildings and anything that could be considered a heritage site.

Not sure which lime to use for a chimney, solid floor, or coping stone? In this episode of Talking Conservation, we explain how to choose and apply the right lime mix for floor construction and high-exposure areas in older homes.
In this episode, Rich and Stephen continue their deep dive into lime mortars, exploring how to apply them in real-world contexts where performance under pressure really matters.
We cover the use of limecrete floors and lime ash floors, debunking common myths about moisture performance and clarifying where lime-based solid floors offer real benefits (and where they don’t).
We also examine high-exposure areas such as chimneys, ridge tiles, parapets, and copings — where material choice is critical. Should you use NHL 3.5? NHL 5? Is cement ever appropriate? We walk through the options and trade-offs.
Whether you're repairing flaunchings or considering a breathable solid floor alternative, this episode gives you practical advice grounded in conservation principles.
